Modification of spasticity by transcutaneous spinal cord stimulation in individuals with incomplete spinal cord injury

Context/objective

To examine the effects of transcutaneous spinal cord stimulation (tSCS) on lower-limb spasticity.

Design

Interventional pilot study to produce preliminary data.

Setting

Department of Physical Medicine and Rehabilitation, Wilhelminenspital, Vienna, Austria.

Participants

Three subjects with chronic motor-incomplete spinal cord injury (SCI) who could walk ≥10 m.

Interventions

Two interconnected stimulating skin electrodes (Ø 5 cm) were placed paraspinally at the T11/T12 vertebral levels, and two rectangular electrodes (8 × 13 cm) on the abdomen for the reference. Biphasic 2 ms-width pulses were delivered at 50 Hz for 30 minutes at intensities producing paraesthesias but no motor responses in the lower limbs.

Outcome measures

The Wartenberg pendulum test and neurological recordings of surface-electromyography (EMG) were used to assess effects on exaggerated reflex excitability. Non-functional co-activation during volitional movement was evaluated. The timed 10-m walk test provided measures of clinical function.

Results

The index of spasticity derived from the pendulum test changed from 0.8 ± 0.4 pre- to 0.9 ± 0.3 post-stimulation, with an improvement in the subject with the lowest pre-stimulation index. Exaggerated reflex responsiveness was decreased after tSCS across all subjects, with the most profound effect on passive lower-limb movement (pre- to post-tSCS EMG ratio: 0.2 ± 0.1), as was non-functional co-activation during voluntary movement. Gait speed values increased in two subjects by 39%.

Conclusion

These preliminary results suggest that tSCS, similar to epidurally delivered stimulation, may be used for spasticity control, without negatively impacting residual motor control in incomplete SCI. Further study in a larger population is warranted.     

Predictors of readmission to acute care during inpatient rehabilitation for non-traumatic spinal cord injury

Objectives: To investigate the frequency of and reasons for readmissions to acute care (RTAC) during inpatient rehabilitation (IPR) after non-traumatic spinal cord injury (NT-SCI). To develop a predictive model for RTAC using identified risk factors.

Design: Retrospective case-control.

Setting: Academic IPR hospital.

Participants: Individuals with NT-SCI admitted to an academic SCI rehabilitation unit from January 2014-December 2015.

Interventions: Not applicable.

Main Outcome Measures: Readmissions to acute care services from IPR.

Results: Thirty-seven participants (20%) experienced a RTAC for a total of 39 episodes. Thirty-five experienced 1 RTAC, while two had 2. The most common medical reasons for RTAC were infection (27%), neurological (27%), and noninfectious respiratory (16%). Multivariable logistic regression was used to develop a model to predict RTAC. Paraplegia was associated with 3.2 times increase in the odds of RTAC (P?=?0.03). For every unit increase in FIM-Motor, there was a 5% reduction in the odds of RTAC (P?=?0.03) Body mass index less than 30 decreased odds of RTAC by 61% (P?=?0.004).

Conclusion: RTACs were associated with body mass index greater than 30, decreased FIM-Motor subscore on admission, and paraplegia. Physiatrists caring for the non-traumatic SCI patient need be more circumspect of individuals with these parameters to potentially prevent the problems necessitating acute care transfer.     

Neurological and functional recovery after thoracic spinal cord injury

Objective

To describe neurological and functional outcomes after traumatic paraplegia.

Design

Retrospective analysis of longitudinal database.

Setting

Spinal Cord Injury Model Systems.

Participants

Six hundred sixty-one subjects enrolled in the Spinal Cord Injury Model Systems database, injured between 2000 and 2011, with initial neurological level of injury from T2–12. Two hundred sixty-five subjects had second neurological exams and 400 subjects had Functional Independence Measure (FIM) scores ≥6 months after injury.

Outcome Measures

American Spinal Injury Association Impairment Scale (AIS) grade, sensory level (SL), lower extremity motor scores (LEMS), and FIM.

Results

At baseline, 73% of subjects were AIS A, and among them, 15.5% converted to motor incomplete. The mean SL increase for subjects with an AIS A grade was 0.33 ± 0.21; 86% remained within two levels of baseline. Subjects with low thoracic paraplegia (T10–12) demonstrated greater LEMS gain than high paraplegia (T2–9), and also had higher 1-year FIM scores, which had not been noted in earlier reports. Better FIM scores were also correlated with better AIS grades, younger age and increase in AIS grade. Ability to walk at 1 year was associated with low thoracic injury, higher initial LEMS, incomplete injury and increase in AIS grade.

Conclusion

Little neurological recovery is seen in persons with complete thoracic SCI, especially with levels above T10. Persons who are older at the time of injury have poorer functional recovery than younger persons. Conversion to a better AIS grade is associated with improvement in self-care and mobility at 1 year.     

The SCIRehab project: treatment time spent in SCI rehabilitation. Psychology treatment time during inpatient spinal cord injury rehabilitation

Background

Rehabilitation psychologists are integral members of spinal cord injury (SCI) rehabilitation teams.

Objective

To describe specific information regarding types and intensity of treatments delivered by rehabilitation psychologists to patients with various levels of SCI.

Methods

Utilizing a taxonomy of psychological interventions as a framework, rehabilitation psychologists documented time spent on specific psychology interventions for each interaction they had with 600 patients with traumatic SCI at 6 inpatient SCI rehabilitation centers. Associations of patient and injury characteristics with time spent on various psychological interventions were examined using ordinary least squares stepwise regression models.

Results

Psychologists focus the majority of the time they spend with patients with SCI on psychotherapeutic interventions of processing emotions, emotional adjustment, and family coping, while educational efforts focus mostly on coping and adjusting to the new injury. There was wide variation in the amount of time spent on psychotherapeutic and psychoeducational interventions; patient, injury, and clinician characteristics explained little of the variation in time spent.

Conclusions

Variations observed in psychological treatment delivery mirror real-world human complexity and clinical experience; they are not explained well by patient and injury characteristics and set the stage for future analyses to associate treatments with outcomes.     

Peer-led,transformative learning approaches increase classroom engagement in care self-management classes during inpatient rehabilitation of individuals with spinal cord injury

Objective: Evaluate effects of revised education classes on classroom engagement during inpatient rehabilitation for individuals with spinal cord injury/disease (SCI/D).

Design: Multiple-baseline, quasi-experimental design with video recorded engagement observations during conventional and revised education classes; visual and statistical analysis of difference in positive engagement responses observed in classes using each approach.

Participants/Setting: 81 patients (72% male, 73% white, mean age 36 SD 15.6) admitted for SCI/D inpatient rehabilitation in a non-profit rehabilitation hospital, who attended one or more of 33 care self-management education classes that were video recorded. All study activities were approved by the host facility institutional review board.

Intervention: Conventional nurse-led self-management classes were replaced with revised peer-led classes incorporating approaches to promote transformative learning. Revised classes were introduced across three subject areas in a step-wise fashion over 15 weeks.

Outcome Measure: Positive engagement responses (asking questions, participating in discussion, gesturing, raising hand, or otherwise noting approval) were documented from video recordings of 14 conventional and 19 revised education classes.

Results: Significantly higher average (per patient per class) positive engagement responses were observed in the revised compared to conventional classes (p=0.008).

Conclusion: Redesigning SCI inpatient rehabilitation care self-management classes to promote transformative learning increased patient engagement. Additional research is needed to examine longer term outcomes and replicability in other settings.     

The SCIRehab project: treatment time spent in SCI rehabilitation. Physical therapy treatment time during inpatient spinal cord injury rehabilitation

Background/objective

To describe the nature and distribution of activities during physical therapy (PT) delivered in inpatient spinal cord injury (SCI) rehabilitation and discuss predictors (patient and injury characteristics) of the amount of time spent in PT for specific treatment activities.

Methods

Six hundred patients from six inpatient SCI centers were enrolled in the SCIRehab study. Physical therapists documented details, including time spent, of treatment provided during 37 306 PT sessions that occurred during inpatient SCI rehabilitation. Ordinary least squares regression models associated patient and injury characteristics with time spent in specific PT activities.

Results

SCIRehab patients received a mean total of 55.3 hours of PT over the course of their rehabilitation stay. Significant differences among four neurologic groups were seen in the amount of time spent on most activities, including the most common PT activities of strengthening exercises, stretching, transfer training, wheelchair mobility training, and gait training. Most PT work (77%) was provided in individual therapy sessions; the remaining 23% was done in group settings. Patient and injury characteristics explained only some of the variations seen in time spent on wheelchair mobility, transfer and bed mobility training, and range of motion/stretching.

Conclusion

Analysis yielded both expected and unexpected trends in SCI rehabilitation. Significant variation was seen in time spent on PT activities within and among injury groups. Providing therapeutic strengthening treatments consumed the greatest proportion of PT time. About one-quarter of all PT services were provided in group settings. Details about services provided, including time spent, will serve as a starting point in detailing the optimal treatment delivery for maximal outcomes.     

The SCIRehab project: treatment time spent in SCI rehabilitation. Occupational therapy treatment time during inpatient spinal cord injury rehabilitation

Background

Occupational therapy (OT) is a critical component of the rehabilitation process after spinal cord injury (SCI), the constitution of which has not been studied or documented in full detail previously.

Objective

To describe the type and distribution of SCI rehabilitation OT activities, including the amount of time spent on evaluation and treatment, and to discuss predictors (patient and injury characteristics) of the amount of time dedicated to OT treatment activities.

Methods

Six inpatient rehabilitation centers enrolled 600 patients with traumatic SCI in the first year of the SCIRehab. Occupational therapists documented 32 512 therapy sessions including time spent and specifics of each therapeutic activity. Analysis of variance and contingency tables/chi-square tests were used to test differences across neurologic injury groups for continuous and categorical variables.

Results

SCIRehab patients received a mean total of 52 hours of OT over the course of their rehabilitation stay. Statistically significant differences among four neurologic injury groups were seen in time spent on each OT activity. The activities that consumed the most OT time (individual and group sessions combined) were strengthening/endurance exercises, activities of daily living (ADLs), range of motion (ROM)/stretching, education, and a grouping of ‘therapeutic activities’ that included tenodesis training, fine motor activities, manual therapy, vestibular training, edema management, breathing exercise, cognitive retraining, visual/perceptual training desensitization, and don/doff adaptive equipment. Seventy-seven percent of OT work occurred in individual treatment sessions, with the most frequent OT activity involving ADLs. The variation in time (mean minutes per week) spent on OT ROM/stretching, ADLs, transfer training, assessment, and therapeutic activities can be explained in part by patient and injury characteristics, such as admission Functional Independence Measure (FIM) score, neurologic injury group, and the medical severity of illness score.

Conclusion

OT treatment patterns for patients with traumatic SCI show much variation in activity selection and time spent on activities, within and among neurologic level of injury groups. Some of the variation can be explained by patient and injury characteristics. Almost all patients with SCI participated in strengthening/endurance and ROM/stretching exercises during OT treatment and these two activities are where the most time was spent when therapy provided in individual and group settings was combined. ADL work consumed the most time in individual therapy sessions.     

The comparison of recovery patterns between ischemic spinal cord injury and traumatic spinal cord injury from acute to chronic phase

Objective: To investigate the neurological and functional recovery patterns of ischemic spinal cord injury (ISCI) compared with traumatic spinal cord injury (TSCI) in the acute to chronic phase.Design: Retrospective cohort study.Settings: Department of Neurology, Neurosurgery, Rehabilitation Medicine at a tertiary hospital.Participants: Fifty-four patients with ISCI and 86 patients with TSCI.Interventions: Not applicable.Outcome measures: MRI findings, American Spinal Injury Association Impairment Scale (AIS), modified Rankin Scale (mRS), Korean Spinal Cord Independence Measure (KSCIM), ambulatory status, and bladder status were reviewed. The functional outcomes were measured at admission, discharge, and >6 months after discharge.Results: AIS classification did not significantly change after 6 months in both ISCI and TSCI groups. Between admission and discharge, the proportion of patients needing a wheelchair or assistive device to ambulate decreased more in the ISCI group compared with the TSCI group [odds ratio (OR) 0.40, P = 0.04]. In addition, the proportion of catheterized voiding in the ISCI group was significantly higher than in the TSCI group at all time points (OR 5.12, P < 0.001). Lastly, both groups showed that functional improvement was the greatest between admission and discharge. In addition, the proportion of catheterized voiding decreased (Diff = −0.12, P = 0.019) and mRS score decreased (Diff=−0.48, P < 0.001) significantly in the ISCI group at >6 months post discharge.Conclusion: The ISCI group showed better recovery of mobility during inpatient rehabilitation period and worse recovery of bladder function as demonstrated by higher number of patients requiring bladder catheterization at all time points when compared with the TSCI group.     

Factors associated with upper extremity contractures after cervical spinal cord injury: A pilot study

Objective: To examine the prevalence of joint contractures in the upper limb and association with voluntary strength, innervation status, functional status, and demographics in a convenience sample of individuals with cervical spinal cord injury to inform future prospective studies.

Design: Cross-sectional convenience sampled pilot study.

Setting: Department of Veterans Affairs Research Laboratory.

Participants: Thirty-eight participants with cervical level spinal cord injury.

Interventions: Not applicable.

Main Outcome Measures: Contractures were measured with goniometric passive range of motion. Every joint in the upper extremity was evaluated bilaterally. Muscle strength was measured with manual muscle testing. Innervation status was determined clinically with surface electrical stimulation. Functional independence was measured with the Spinal Cord Independence Measure III (SCIM-III).

Results: Every participant tested had multiple joints with contractures and, on average, participants were unable to achieve the normative values of passive movement in 52% of the joints tested. Contractures were most common in the shoulder and hand. There was a weak negative relationship between percentage of contractures and time post-injury and a moderate positive relationship between percentage of contractures and age. There was a strong negative correlation between SCIM-III score and percentage of contractures.

Conclusions: Joint contractures were noted in over half of the joints tested. These joint contractures were associated with decreased functional ability as measured by the SCIM-III. This highlights the need the need for detailed evaluation of the arm and hand early after injury as well as continued monitoring of joint characteristics throughout the life course of the individual with tetraplegia.     

Prediction of functional recovery six months following traumatic spinal cord injury during acute care hospitalization

Objectives: To determine factors associated with functional status six months following a traumatic cervical and thoracic spinal cord injury (SCI), with a particular interest in factors related to the acute care hospitalization stay.

Design: This is a prospective cohort study. Sixteen potential predictive variables were studied. Univariate regression analyses were first performed to determine the strength of association of each variable independently with the total Spinal Cord Independence Measure (SCIM) score. Significant ones were then included in a General linear model in order to determine the most relevant predictive factors among them. Analyses were carried out separately for tetraplegia and paraplegia.

Setting: A single specialized Level I trauma center.

Participants: One hundred fifty-nine patients hospitalized for an acute traumatic SCI between January 2010 and February 2015.

Interventions: Not applicable.

Main outcome measure: The SCIM (version 3) functional score.

Results: Motor-complete SCI (AIS-A,B) was the main predictive factor associated with decreased total SCIM score in tetraplegia and paraplegia. Longer acute care length of stay and the occurrence of acute medical complications (either pneumonia, urinary tract infections or pressure ulcers) were predictors of decreased functional outcome following tetraplegia, while increased body mass index and higher trauma severity were predictive of decreased functional outcome following paraplegia.

Conclusions: This study supports previous work while adding information regarding the importance of optimizing acute care hospitalization as it may influence chronic functional status following traumatic SCI.     

Predictors of functional outcomes in adults with traumatic spinal cord injury following inpatient rehabilitation: A systematic review

Context: Despite functional improvements during rehabilitation, variable functional outcomes were reported when patients with Spinal Cord Injury (SCI) return to society. Higher functioning individuals at discharge can experience a decrease in independent mobility (i.e. Motor Functional Independence Measure (mFIM) Score) by one-year follow-up. However, functional gains after discharge have also been reported and associated with recovery.

Objective: To identify, categorize and rank predictors of mFIM score for patients with SCI following inpatient rehabilitation, both at the time of discharge and at one-year follow-up.

Methods: Data sources included CINAHL, PubMed, ERIC, Google Scholar, and Medline for literature published from February 2000 to February 2015. Quality and risk of bias of included studies was assessed using the Risk of Bias Assessment Instrument for Prognostic Factor Studies (QUIPS). Significant predictors of mFIM score were categorized using the domains of the International Classification of Function and Disability model ICF and ranked based on how frequently they were significant predictors of mFIM score.

Results: Twenty-seven predictors of mFIM score spanning the ICF domains were identified among seven studies. At discharge, variables in the Body Structure and Function domain were the most consistent predictors of mFIM score. At one-year follow-up, variables in the Activity and Participation domain were the most consistent predictors of mFIM score. Contextual factors were the least frequent predictors at both discharge and one-year follow-up.

Conclusion: This systematic-review assists clinicians setting realistic goals that maximize functional independence at the time of discharge and after reintegrating to society.     

早期康复干预对脊髓损伤后康复时间的影响

目的:观察脊髓损伤后康复治疗的起始时间对不同节段脊髓损伤(SCI)病例达到康复目标所需的时间、残损分级变化和并发症发生率的影响。方法:采用多家医疗机构协作进行前瞻性病例观察方法,事先预定康复方案,同时开始纳入SCI病例。病例入组后,参照国际标准为其制定康复目标和方案。在开始康复训练后进行跟踪观察,包括记录康复时间(受伤至达到康复目标所需时间),评估康复前后的ASIA残损分级及并发症的发生率。2009年1月~2012年12月4年里先后共入组观察521例患者,男419例,女102例,年龄38.5±12.1岁(18~74岁),随访20±8个月(10~38个月)。按受伤至入组的时间长短,将病例分为围手术期组、术后组和延迟组。各组按SCI节段不同再细分为高位颈髓损伤、低位颈髓损伤、胸髓损伤、腰骶段损伤四群。最终将观察结果进行组内组间对比分析。结果:在围手术期组的高位颈髓损伤、低位颈髓损伤、胸髓损伤和腰骶损伤病例中,运动完全损伤者(A、B级)所需康复时间中位数分别为238d、160d、97d和62d,运动不完全损伤者(C、D级)所需康复时间分别为153d、128d、72d和46d。术后组各群SCI的康复时间比围手术期组相同群SCI增加16~30d(P0.05)。在延迟组,各群SCI的康复时间较前两组均明显增加(P0.05),特别是低位颈髓损伤、胸髓损伤和腰骶损伤A、B级病例较围手术期组成倍增加(P0.05)。同一组患者中,相同ASIA残损分级,损伤平面越低,康复时间越短(P0.05);同一损伤平面,损伤越重,康复时间越长(P0.05)。在达到康复目标时,A~D级病例中有一个级别改善的比率分别为A级3.8%、B级13.6%、C级34.0%和D级7.7%,有两个级改善的比率为A级2.35%、B级2.1%、C级0.09%和D级0%。围手术期康复组压疮、下肢深静脉血栓、下尿路感染和肺部感染的发生率分别为6.2%、5.5%、15.4%和11.1%,均明显低于另外两组(P0.05)。结论:早期康复干预能降低SCI并发症的发生率,从而缩短康复时间,但对残损分级变化无明确影响。SCI康复所需时间大约为3~9个月,损伤平面越高、程度越重,所需康复时间越长。运动完全损伤者康复前后ASIA残损分级无明显变化。     

Peer mentoring reduces unplanned readmissions and improves self-efficacy following inpatient rehabilitation for individuals with spinal cord injury

ObjectiveEvaluate effectiveness of peer interventions on self-efficacy, unplanned hospital readmissions, and quality of life for patients with spinal cord injury (SCI) undergoing inpatient rehabilitation.DesignInterrupted time-series analysis (ITSA) examined effects of peer interventions on unplanned readmissions. Intervention variables added to ITSA regression examined relationships with exposure to peer interventions. Heterogeneity of treatment effects (HTE) analysis examined differences in intervention effectiveness for patients with quadriplegia and paraplegia.SettingRehabilitation hospital specializing in SCI and brain injury.ParticipantsSCI inpatients (n = 1117) admitted for rehabilitation whose discharge location was home (77% male, 71% Caucasian, mean age 38.2 (SD 16.8)). A subsample of 799 patients participated in secondary analyses examining relationship between peer interventions, readmissions, changes in patient-reported outcomes, and HTE.InterventionsOne-to-one mentoring and participation in peer-led self-management classes.Main outcome measuresUnplanned readmissions, general self-efficacy (GSE), and depressive symptoms 30, 90, and 180 days post discharge; satisfaction with life at 180 days.ResultsAfter implementing the peer interventions, we observed a significant decrease in both level and slope of number of patients readmitted, and level only of unplanned hospital days 30-days post-discharge. Reduction in the number of patients and unplanned hospital days was associated with number of peer visits but not peer-led education classes attended. Higher self-efficacy (GSE) was associated with greater exposure to peer mentoring, and a significant relationship between improvement in GSE and reduced hospital readmissions was observed.ConclusionsOne-to-one peer mentoring improves self-efficacy and reduces unplanned hospital readmissions following inpatient rehabilitation for persons with SCI.     

Urodynamic patterns after traumatic spinal cord injury

Objectives

To study the correlation between neurological level of spinal injury and bladder functions as detected by urodynamic study.

Study design

Analytical study.

Setting and participants

Seventy individuals with traumatic spinal cord injury (SCI) admitted to the Department of Physical Medicine and Rehabilitation, S.M.S. Medical College and Hospital, Jaipur. Detailed clinical, neurological evaluation as per American Spinal Injury Association Classification and radiological assessment were done along with clinical examination of bladder and urodynamic study.

Results

Out of 65 patients with suprasacral injuries, 53 (81.5%) demonstrated hyperreflexia with or without detrusor sphincter dyssynergia, 6 (9.2%) detrusor areflexia, and 6 (9.2%) had normal bladders, 41 (59.4%) low compliance (<20 ml/cmH₂O), and 47 (72.30%) had high detrusor leak pint pressures (>40 cmH₂O). Of the five patients with sacral injuries, one (20%) showed detrusor hyperreflexia, four (80%) detrusor areflexia, and one (20%) had low bladder compliance; all five (100%) had high detrusor leak point pressures.

Conclusions

The correlation between somatic neurologic findings, spinal imaging studies, and urodynamic findings in patients with SCI is not exact. Therefore, bladder management should not completely rely only on clinical bladder evaluation or neurological examination alone, but should always include urodynamic studies.     

Inpatient rehabilitation outcomes in patients with malignant spinal cord compression compared to other non-traumatic spinal cord injury: A population based study

Abstract

Objective

To compare and describe demographic characteristics, clinical, and survival outcomes in patients admitted for inpatient rehabilitation following malignant spinal cord compression (MSCC) or other causes of non-traumatic spinal cord injury (NT-SCI).

Design

A retrospective cohort design was employed, using data retrieved from administrative databases.

Setting

Rehabilitation facilities or designated rehabilitation beds in Ontario, Canada, from April 2007 to March 2011.

Participants

Patients with incident diagnoses of MSCC (N = 143) or NT-SCI (N = 1,274) admitted for inpatient rehabilitation.

Outcome measures

Demographic, impairment, functional outcome (as defined by the Functional Independence Measure (FIM)), discharge, healthcare utilization, survival, and tumor characteristics.

Results

There was a significant improvement in the FIM from admission to discharge (mean change 20.1 ± 14.3, <0.001) in the MSCC cohort. NT-SCI patients demonstrated a higher FIM efficiency (1.2 ± 1.7 vs. 0.8 ± 0.8, <0.001) and higher total (24.0 ± 14.4 vs. 20.1 ± 14.3, <0.001) FIM gains relative to MSCC cases. However, there were no differences between the MSCC and NT-SCI cohorts in length of stay (34.6 ± 30.3 vs. 37.5 ± 35.2, P = 0.8) or discharge FIM (100.7 ± 19.6 vs. 103.3 ± 18.1, P = 0.1). Three-month, 1-year, and 3-year survival rates in the MSCC and NT-SCI cohorts were 76.2% vs. 97.6%, 46.2% vs. 93.7%, and 27.3% vs. 86.7%, respectively. The majority (65.0%) of patients with MSCC was discharged home and met their rehabilitation goals (75.5%) at comparable rates to patients with NT-SCI (69.7 and 81.3%).

Conclusion

Despite compromised survival, patients with MSCC make clinically significant functional gains and exhibit favorable discharge outcomes following inpatient rehabilitation. Current administrative data suggests the design and scope of inpatient rehabilitation services should reflect the unique survival-related prognostic factors in patients with MSCC.     

Inpatient rehabilitation outcomes in neoplastic spinal cord compression vs. traumatic spinal cord injury

Objective: To compare neurological and functional outcomes, and complications of patients with neoplastic vs traumatic spinal cord injury (SCI) after in-patient rehabilitation.Design: This study is a retrospective analysis.Setting: In-patient rehabilitation unit of a tertiary research hospital.Participants: A total of 252 patients with a SCI were included; 43 with neoplastic SCI (mean age: 60.9 ± 15.7 years, 60.5% were males) and 209 with traumatic SCI (mean age: 43.1 ± 16.8 years, 71.3% were males).Outcome measures: Comparisons were made of demographic characteristics, etiology, American Spinal Injury Association (ASIA) impairment scale, functional independence measurement (FIM) and Functional Ambulation Categories (FAC) scores, length of stay (LOS), bladder independence, medical comorbidities and complications in both groups.Results: Patients with neoplastic SCI were significantly older than those with traumatic SCI (P < 0.01). No difference was present between the groups in terms of sex and lesion level (P > 0.05). Incomplete SCI was significantly higher in the neoplastic group when compared with the traumatic group (P < 0.01). The LOS was significantly shorter in the neoplastic group than traumatic group (34.8 ± 41.03 vs. 60.02 ± 53.1, P < 0.01). There were no differences in the admission FIM scores (69.3 ± 24.7 vs. 58.7 ± 18.9, P > 0.05), discharge FIM scores (82.1 ± 25.1 vs. 74.02 ± 23.3, P > 0.05) and FIM efficiencies (0.43 ± 0.72 vs. 0.36 ± 0.51, P > 0.05) for the neoplastic and traumatic groups, respectively. However, neoplastic SCI patients demonstrated lower FIM gains compared to traumatic patients (12.9 ± 11.9 vs. 15.4 ± 15.2, P < 0.05). During rehabilitation, urinary tract infection (48.4% vs. 69.4%) and decubitus ulcer (11.6% vs. 35.9%) were significantly more common in the traumatic group than the neoplastic group (P < 0.05).Conclusion: Neoplastic SCI patients who commonly present at rehabilitation units exhibit different characteristics from traumatic SCI patients but the rehabilitation results are similar. Similar functional development can be achieved in a shorter period of time with inpatient rehabilitation in the neoplastic SCI group.     

Team size in spinal cord injury inpatient rehabilitation and patient participation in therapy sessions: The SCIRehab Project

Context/objective

Rehabilitation teams generally are described as consisting of a single representative of 6–8 disciplines, but research suggests that the number of individuals involved may be much larger. This study aimed to determine the size of teams in spinal cord injury (SCI) rehabilitation, and the effect of team size on patients'' active participation in their treatment sessions.

Design

Prospective observational study.

Setting

Six SCI rehabilitation centers.

Participants

A total of 1376 patients with traumatic SCI admitted for first rehabilitation.

Interventions

Not applicable.

Outcome measures

Number of treatment sessions, by discipline and overall clinician rating of active participation of the patient; Treatment Concentration Index (TCI) calculated as Σp_k² (where p refers to the proportion of treatment sessions delivered by team member k).

Results

The average patient was treated by 39.3 different clinicians. The numbers were especially high for physical therapy (mean: 8.8), occupational therapy (7.2), and nursing (16.1). TCI was 0.08 overall; it varied by discipline. TCI was negatively correlated with length of stay, except for psychology. Participation ratings were minimally affected by the number of sessions the patient and the therapist had worked together.

Conclusions

In SCI rehabilitation, teams are at least as large as suggested by previous research. However, this may not mean lack of familiarity of patient and therapist with one another, or alternatively, the possibly weak therapeutic alliance does not affect the patients'' active participation in their sessions. Further research is needed to determine whether there are negative effects on rehabilitation outcomes.     

Inpatient rehabilitation outcomes in patients with malignant spinal cord compression compared to other non-traumatic spinal cord injury: A population based study

ObjectiveTo compare and describe demographic characteristics, clinical, and survival outcomes in patients admitted for inpatient rehabilitation following malignant spinal cord compression (MSCC) or other causes of non-traumatic spinal cord injury (NT-SCI).DesignA retrospective cohort design was employed, using data retrieved from administrative databases.SettingRehabilitation facilities or designated rehabilitation beds in Ontario, Canada, from April 2007 to March 2011.ParticipantsPatients with incident diagnoses of MSCC (N = 143) or NT-SCI (N = 1,274) admitted for inpatient rehabilitation.ResultsThere was a significant improvement in the FIM from admission to discharge (mean change 20.1 ± 14.3, <0.001) in the MSCC cohort. NT-SCI patients demonstrated a higher FIM efficiency (1.2 ± 1.7 vs. 0.8 ± 0.8, <0.001) and higher total (24.0 ± 14.4 vs. 20.1 ± 14.3, <0.001) FIM gains relative to MSCC cases. However, there were no differences between the MSCC and NT-SCI cohorts in length of stay (34.6 ± 30.3 vs. 37.5 ± 35.2, P = 0.8) or discharge FIM (100.7 ± 19.6 vs. 103.3 ± 18.1, P = 0.1). Three-month, 1-year, and 3-year survival rates in the MSCC and NT-SCI cohorts were 76.2% vs. 97.6%, 46.2% vs. 93.7%, and 27.3% vs. 86.7%, respectively. The majority (65.0%) of patients with MSCC was discharged home and met their rehabilitation goals (75.5%) at comparable rates to patients with NT-SCI (69.7 and 81.3%).ConclusionDespite compromised survival, patients with MSCC make clinically significant functional gains and exhibit favorable discharge outcomes following inpatient rehabilitation. Current administrative data suggests the design and scope of inpatient rehabilitation services should reflect the unique survival-related prognostic factors in patients with MSCC.     

Scoping review of peer reviewed publications addressing rehabilitation for people sustaining traumatic spinal cord injury

Study Design: Scoping review

Objective: To study the design, clinical setting and outcome measures used in spinal cord injury rehabilitation publications.

Methods: A literature search on PubMed and Medline was conducted focusing on articles published between 1990–2016 and using “traumatic SCI”, “functional outcomes”, “rehabilitation”, “work” and “return to work” as outcomes. Studies were categorized based on design (intervention, including RCTs vs. non-intervention studies), settings (inpatient vs. outpatient vs. transition), and outcome measures used (impairment vs. function vs. participation/integration vs. quality of life vs. symptoms). Work-related studies were categorized independently.

Results: Five hundred forty-four articles met the inclusion criteria. Of these, 234 were interventional studies, including 23 RCTs. Studies were evenly divided among inpatient, outpatient and transition settings. Of the 234 interventional studies, 143 used functional evaluations. Sixty-one different functional instruments were used, with a predominant use of the Functional Independence Measure (61 times) and an additional use of SCI-specific measures, i.e. Spinal Cord Independence Measure and Craig Handicap Assessment and Reporting Technique (13 times each). Fifty-one studies measured mobility, while only three measured hand functions. The work-related sub-analysis revealed 32 intervention studies (no RCTs), of which 15 used functional evaluations and only three focused on tetraplegia.

Conclusion: Our study revealed a paucity of intervention trials and RCTs, indicating a dearth of knowledge that would be needed to establish evidence-based practice guidelines. This is particularly true for tetraplegia. While standard measures of function were frequently used, providing valuable data, there is no consensus about what exact outcome measure to use. Using newer measurement techniques, for instance based on the application of item response theory, should be considered to enhance uniformity.
