Examining implicit bias of physicians who care for individuals with spinal cord injury: A pilot study and future directions

Context

Despite evidence that healthcare providers have implicit biases that can impact clinical interactions and decisions, implicit bias among physicians caring for individuals with spinal cord injury (SCI) has not been examined.

Objective

Conduct a pilot study to examine implicit racial bias of SCI physicians and its association with functioning and wellbeing for individuals with SCI.

Design

Combined data from cross-sectional surveys of individuals with SCI and their SCI physicians.

Setting

Four national SCI Model Systems sites.

Participants

Individuals with SCI (N = 162) and their SCI physicians (N = 14).

Outcome measures

SCI physicians completed online surveys measuring implicit racial (pro-white/anti-black) bias. Individuals with SCI completed questionnaires assessing mobility, physical independence, occupational functioning, social integration, self-reported health, depression, and life satisfaction. We used multilevel regression analyses to examine the associations of physician bias and outcomes of individuals with SCI.

Results

Physicians had a mean bias score of 0.62 (SD = 0.35), indicating a strong pro-white/anti-black bias. Greater physician bias was associated with disability among individuals with SCI in the domain of social integration (odds ratio = 4.80, 95% confidence interval (CI) = 1.44, 16.04), as well as higher depression (B = 3.24, 95% CI = 1.06, 5.41) and lower life satisfaction (B = −4.54, 95% CI= −8.79, −0.28).

Conclusion

This pilot study indicates that SCI providers are susceptible to implicit racial bias and provides preliminary evidence that greater implicit racial bias of physicians is associated with poorer psychosocial health outcomes for individuals with SCI. It demonstrates the feasibility of studying implicit bias among SCI providers and provides guidance for future research on physician bias and patient outcomes.     

Assessment of passive knee stiffness and viscosity in individuals with spinal cord injury using pendulum test

Objective

Stiffness and viscosity represent passive resistances to joint motion related with the structural properties of the joint tissue and of the musculotendinous complex. Both parameters can be affected in patients with spinal cord injury (SCI). The purpose of this study was to measure passive knee stiffness and viscosity in patients with SCI with paraplegia and healthy subjects using Wartenberg pendulum test.

Design

Non-experimental, cross-sectional, case–control design.

Setting

An outpatient physical therapy clinic, University of social welfare and Rehabilitation Science, Iran.

Patients

A sample of convenience sample of 30 subjects participated in the study. Subjects were categorized into two groups: individuals with paraplegic SCI (n = 15, age: 34.60 ± 9.18 years) and 15 able-bodied individuals as control group (n = 15, age: 30.66 ± 11.13 years).

Interventions

Not applicable.

Main measures

Passive pendulum test of Wartenberg was used to measure passive viscous-elastic parameters of the knee (stiffness, viscosity) in all subjects.

Results

Statistical analysis (independent t-test) revealed significant difference in the joint stiffness between healthy subjects and those with paraplegic SCI (P = 0.01). However, no significant difference was found in the viscosity between two groups (P = 0.17). Except for first peak flexion angle, all other displacement kinematic parameters exhibited no statistically significant difference between normal subjects and subjects with SCI.

Conclusions

Patients with SCI have significantly greater joint stiffness compared to able-bodied subjects.     

Dietary intake and adherence to the 2010 Dietary Guidelines for Americans among individuals with chronic spinal cord injury: A pilot study

Objective

To investigate dietary intake and adherence to the 2010 Dietary Guidelines for Americans in individuals with chronic spinal cord injury (SCI) and able-bodied individuals.

Design

A pilot study of dietary intake among a sample of individuals with SCI >1 year ago from a single site compared with able-bodied individuals.

Participants/methods

One hundred black or white adults aged 38–55 years old with SCI >1 year and 100 age-, sex-, and race-matched adults enrolled in the Coronary Artery Risk Development in Young Adults (CARDIA) study. Dietary intake was assessed by the CARDIA dietary history. Linear regression analysis was used to compare dietary intake between the subjects with SCI and those enrolled in the CARDIA study. Further, adherence to the 2010 Dietary Guidelines for dairy, fruits, and vegetables, and whole-grain foods was assessed.

Results

Compared with CARDIA participants, participants with SCI consumed fewer daily servings of dairy (2.10 vs. 5.0, P < 0.001), fruit (2.01 vs. 3.64, P = 0.002), and whole grain foods (1.20 vs. 2.44 P = 0.007). For each food group, fewer participants with SCI met the recommended servings compared with the CARDIA participants. Specifically, the participants with SCI and in CARDIA who met the guidelines were, respectively: dairy, 22% vs. 54% (P < 0.001), fruits and vegetables 39% vs. 70% (P = 0.001), and whole-grain foods 8% vs. 69.6% (P = 0.001).

Conclusions

Compared with able-bodied individuals, SCI participants consumed fewer daily servings of fruit, dairy, and whole grain foods than proposed by the 2010 Dietary Guideline recommendations. Nutrition education for this population may be warranted.     

Physical exercise improves arterial stiffness after spinal cord injury

Objective/background

Aortic pulse wave velocity (PWV), the gold-standard assessment of central arterial stiffness, has prognostic value for cardiovascular disease risk in able-bodied individuals. The aim of this study was to compare aortic PWV in athletes and non-athletes with spinal cord injury (SCI).

Design

Cross-sectional comparison.

Methods

Aortic PWV was assessed in 20 individuals with motor-complete, chronic SCI (C2–T5; 18 ± 8 years post-injury) using applanation tonometry at the carotid and femoral arterial sites. Ten elite hand-cyclists were matched for sex to 10 non-athletes; age and time since injury were comparable between the groups. Heart rate and discrete brachial blood pressure measurements were collected throughout testing.

Outcome measures

Aortic PWV, blood pressure, heart rate.

Results

Aortic PWV was significantly lower in athletes vs. non-athletes (6.9 ± 1.0 vs. 8.7 ± 2.5 m/second, P = 0.044). There were no significant between-group differences in resting supine mean arterial blood pressure (91 ± 19 vs. 81 ± 10 mmHg) and heart rate (60 ± 10 vs. 58 ± 6 b.p.m.).

Conclusion

Athletes with SCI exhibited improved central arterial stiffness compared to non-athletes, which is in agreement with the previous able-bodied literature. This finding implies that chronic exercise training may improve arterial health and potentially lower cardiovascular disease risk in the SCI population.     

Association between alendronate,serum alkaline phosphatase level,and heterotopic ossification in individuals with spinal cord injury

Context/objective

Only sparse evidence exists regarding the effectiveness of oral alendronate (ALN) in the prevention of heterotopic ossification (HO) in patients with spinal cord injury (SCI). The objective of this study is to investigate the protective effect of oral ALN intake on the appearance of HO in patients with SCI.

Study design

Retrospective database review.

Setting

A Spinal Cord Unit at a Rehabilitation Hospital.

Participants

Two hundred and ninety-nine patients with SCI during acute inpatient rehabilitation.

Interventions

Administration of oral ALN.

Outcome measures

The incidence of HO during rehabilitation was compared between patients with SCI receiving oral ALN (n = 125) and patients with SCI not receiving oral ALN (n = 174). The association between HO and/or ALN intake with HO risk factors and biochemical markers of bone metabolism were also explored.

Results

HO developed in 19 male patients (6.35%), however there was no significant difference in the incidence of HO in patients receiving oral ALN or not. The mean odds ratio of not developing versus developing HO given ALN exposure was 0.8. Significant correlation was found between abnormal serum alkaline phosphatase (ALP) levels and HO appearance (P < 0.001) as well as normal serum ALP and ALN intake (P < 0.05).

Conclusion

Even though there was no direct prevention of HO in patients with SCI by oral ALN intake, abnormal serum ALP was found more frequently in patients with HO development and without oral ALN intake. This evidence could suggest that ALN may play a role in preventing HO, especially in patients with acute SCI with increasing levels of serum ALP.     

Trunk strength and function using the multidirectional reach distance in individuals with non-traumatic spinal cord injury

Context

Trunk control is essential to engage in activities of daily living. Measuring trunk strength and function in persons with spinal cord injury (SCI) is difficult. Trunk function has not been studied in non-traumatic SCI (NTSCI).

Objectives

To characterize changes in trunk strength and seated functional reach in individuals with NTSCI during inpatient rehabilitation. To determine if trunk strength and seated reach differ between walkers and wheelchair users. To explore relationships between trunk and hip strength and seated functional reach.

Design

Observational study.

Setting

Two SCI rehabilitation facilities.

Participants

32 subacute inpatients (mean age 48.0 ± 15.4 years).

Outcome measures

Isometric strength of trunk and hip and function (Multidirectional Reach Test: MDRT) were assessed at admission and within 2 weeks of discharge. Analysis of variance was conducted for admission measures (MDRT, hip and trunk strength) between walkers and wheelchair users. Changes in MDRT, hip and trunk strength were evaluated using parametric and non-parametric statistics. The level of association between changes in values of MRDT and strength was also examined.

Results

Significant differences between walkers and wheelchair users were found for strength measures (P < 0.05) but not for MDRT. Left- and right-sided reaches increased in wheelchair users only (P < 0.05). Associations between changes in hip strength, trunk strength, and reach distance were found (R = 0.67–0.73).

Conclusion

In clinical settings, it is feasible and relevant to assess trunk, hip strength, and MRDT. Future studies require strategies to increase the number of participants assessed, in order to inform clinicians about relevant rehabilitation interventions.     

Do risk perceptions explain sex differences in community integration and participation after spinal cord injury?

Objective

To describe how men and women with spinal cord injury (SCI) rate the risks posed by a set of everyday activities measured using the Risk Inventory for persons with Spinal Cord Injury (RISCI), and to examine whether sex differences are related to community integration and participation.

Design

Cohort study.

Setting

Metropolitan Detroit.

Participants

One hundred and forty community-dwelling white and African-American men and women with SCI.

Outcome measures

RISCI scores, community integration, and level of and satisfaction with community participation.

Results

Study participants were just over age 40 years, and had been living with SCI for 10.8 years. One-third were women and 40% were African-American. Results showed women with SCI had higher RISCI scores (perceived more dangers) on every item on the RISCI Scale (P < 0.001). The items perceived to hold greatest risk were revealing personal information to others, going on a blind date, and going for a roll (“walk”) alone after dark. Women with higher RISCI scores reported lower community integration (P < 0.05) and lower levels of and lower satisfaction with community participation (P < 0.01). For men, however, RISCI scores were mainly unrelated (except for community integration) to participation measures.

Conclusion

More research is needed to determine whether the levels of risk perceived by women are warranted and whether a sense of vulnerability for women with SCI is unnecessarily limiting their chances at “a good life” after injury.     

Effect of whole-body vibration on lower-limb EMG activity in subjects with and without spinal cord injury

Objective

Traumatic spinal cord injury (SCI) results in substantial reductions in lower extremity muscle mass and bone mineral density below the level of the lesion. Whole-body vibration (WBV) has been proposed as a means of counteracting or treating musculoskeletal degradation after chronic motor complete SCI. To ascertain how WBV might be used to augment muscle and bone mass, we investigated whether WBV could evoke lower extremity electromyography (EMG) activity in able-bodied individuals and individuals with SCI, and which vibration parameters produced the largest magnitude of effect.

Methods

Ten male subjects participated in the study, six able-bodied and four with chronic SCI. Two different manufacturers'' vibration platforms (WAVE^® and Juvent™) were evaluated. The effects of vibration amplitude (0.2, 0.6 or 1.2 mm), vibration frequency (25, 35, or 45 Hz), and subject posture (knee angle of 140°, 160°, or 180°) on lower extremity EMG activation were determined (not all combinations of parameters were possible on both platforms). A novel signal processing technique was proposed to estimate the power of the EMG waveform while minimizing interference and artifacts from the plate vibration.

Results

WBV can elicit EMG activity among subjects with chronic SCI, if appropriate vibration parameters are employed. The amplitude of vibration had the greatest influence on EMG activation, while the frequency of vibration had lesser but statistically significant impact on the measured lower extremity EMG activity.

Conclusion

These findings suggest that WBV with appropriate parameters may constitute a promising intervention to treat musculoskeletal degradation after chronic SCI.     

Reliability of the sit-up test in individuals with spinal cord injury

Objective

To determine the day-to-day reliability of blood pressure responses during a sit-up test in individuals with a traumatic spinal cord injury (SCI).

Design

Within-subject, repeated measures design.

Setting

Community outpatient assessments at a research laboratory at the University of British Columbia.

Participants

Five men and three women with traumatic SCI (age: 31 ± 6 years; C4-T11; American Spinal Injury Association Impairment Scale A-B; 1–17 years post-injury).

Outcome measure

Maximum change in systolic (ΔSBP) and diastolic (ΔDBP) blood pressure upon passively moving from a supine to seated position.

Results

The average values for ΔSBP were –11 ± 13 mmHg (range –38 to 3 mmHg) for visit 1, and −12 ± 8 mmHg (range −26 to −1 mmHg) for visit 2. The average values for ΔDBP were −9 ± 8 mmHg (range -21 to 0 mmHg) for visit 1, and –13 ± 8 mmHg (range –29 to –3 mmHg) for visit 2. The ΔSBP demonstrated substantial reliability with an intraclass correlation coefficient of 0.79 (P = 0.006; 95% CI 0.250–0.953), while the ΔDBP demonstrated almost perfect reliability with an intraclass correlation coefficient of 0.92 (P < 0.001; 95% CI 0.645–0.983). The smallest detectable differences in ΔSBP and ΔDBP were 7 mmHg and 6 mmHg, respectively.

Conclusion

Blood pressure responses to the sit-up test are reliable in individuals with SCI, which supports its implementation as a practical bedside assessment for orthostatic hypotension in this at risk population.     

Dermatological problems following spinal cord injury in Korean patients

Objective

To identify dermatological conditions following spinal cord injury (SCI) and analyze these conditions in relation to various characteristics of SCI.

Design

Retrospective chart review.

Setting

National Health Insurance Corporation Ilsan Hospital of Korea, Rehabilitation Center, Spinal Cord Unit.

Participants

Patients treated for SCI who were referred to dermatology for dermatological problems, 2000–2012.

Results

Of the 1408 SCI patients treated at the spinal cord unit, 253 patients with SCI were identified to have been referred to dermatology for skin problems and a total of 335 dermatological conditions were diagnosed. The most common dermatological finding was infectious (n = 123, 36.7%) followed by eczematous lesions (n = 109, 32.5%). Among the infectious lesions, fungal infection (n = 76, 61.8%) was the most common, followed by bacterial (n = 27, 21.9%) lesions. Seborrheic dermatitis (n = 59, 64.1%) was the most frequent eczematous lesion. Ingrown toenail occurred more frequently in tetraplegics whereas vascular skin lesions occurred more commonly in patients with paraplegia (P < 0.05). Xerotic dermatitis showed a higher occurrence within 12 months of injury rather than thereafter (P < 0.05). Of these, 72.4% of the infectious and 94.7% of the fungal skin lesions manifested below the neurological level of injury (NLI; P < 0.001) and 61.5% of the eczematous lesions and 94.9% of seborrheic dermatitis cases occurred above the NLI (P < 0.001). There was no significant difference in dermatological diagnoses between patients with neurologically complete and incomplete SCI.

Conclusion

The most common dermatological condition in patients with SCI among those referred to dermatology was fungal infection, followed by seborrheic dermatitis. Although dermatological problems after SCI are not critical in SCI outcome, they negatively affect the quality of life. Patients and caregivers should be educated about appropriate skin care and routine dermatological examinations.     

Circulating angiogenic biomolecules at rest and in response to upper-limb exercise in individuals with spinal cord injury

Objective

Individuals with spinal cord injury (SCI) show structural and functional vascular maladaptations and muscle loss in their lower limbs. Angiogenic biomolecules play important roles in physiological and pathological angiogenesis, and are implicated in the maintenance of muscle mass. This study examined the responses of angiogenic molecules during upper-limb aerobic exercise in patients with SCI and in able-bodied (AB) individuals.

Methods

Eight SCI patients with thoracic lesions (T₆–T₁₂, ASIA A) and eight AB individuals performed an arm-cranking exercise for 30 minutes at 60% of their VO_2max. Plasma concentrations of vascular endothelial growth factor (VEGF-A₁₆₅), VEGF receptor 1 (sVEGFr-1), VEGF receptor 2 (sVEGFr-2), metalloproteinase 2 (MMP-2), and endostatin were measured at rest, after exercise, and at 1.5 and 3.0 hours during recovery.

Results

The two-way analysis of variance showed non-significant main effects of “group” and significant main effects of “time/exercise” for all angiogenic biomolecules examined (P < 0.01–0.001). The arm-cranking exercise significantly increased plasma concentrations of VEGF, sVEGFr-1, sVEGFr-2, MMP-2, and endostatin in both groups (P < 0.001–0.01). The magnitude of the increase was similar in both patients with SCI and AB individuals, as shown by the non-significant group × time interaction for all angiogenic parameters.

Conclusions

Upper-limb exercise (arm-cranking for 30 minutes at 60% of VO_2max) is a sufficient stimulus to trigger a coordinated circulating angiogenic response in patients with SCI. The response of angiogenic molecules to upper-limb aerobic exercise in SCI appears relatively similar to that observed in AB individuals.     

Functional assessments for predicting a risk of multiple falls in independent ambulatory patients with spinal cord injury

Background/objectives

Many ambulatory patients with spinal cord injury (SCI) encountered multiple falls and serious consequences after falls, but there was no quantitative practical measure for early identification of individuals at a risk of multiple falls. This study compared the utility of the Berg Balance Scale, Timed “Up & Go” Test, 10-Meter Walk Test, Functional Reach Test (FRT), Step Test, and Five Times Sit-to-Stand Test to predict risk of multiple falls (fall ≥2 times) in these individuals.

Methods

Eighty-three independent ambulatory subjects with SCI were assessed for their functional abilities using the six tests. Then, their fall data were monitored prospectively every 2 weeks for 6 months in total. The first 25 subjects were also involved in the reliability tests.

Results

The FRT showed the best predictive ability for the risk of multiple falls (cut-off score ≥20 cm, sensitivity = 73%, specificity = 55%, area under the receiver characteristic curve = 0.64, and adjusted odd ratio = 3.18, P < 0.05), excellent inter-tester reliability, and good feasibility.

Conclusions

The FRT may be used as a screening tool to predict risk of multiple falls in independent ambulatory individuals with SCI. However, with a moderate level of specificity, a further comprehensive test may be needed to clearly indicate individuals at a risk of falls. In addition, the findings suggest that a higher level of ability increases the risk of multiple falls. Thus, programs for functional integration in an actual environment may be needed to reduce the risk of falls for these individuals.     

Evaluation of bone mineral loss in patients with chronic traumatic spinal cord injury in Iran

Objectives

We described the associations between demographic and injury-related factors on bone mineral density (BMD) of the spine and the hip among adult patients with chronic spinal cord injury (SCI).

Design

BMD in spinal and femoral bone sites were assessed. Multivariate analysis was performed to evaluate the relationship between anthropometric and injury-related factors with BMD. Serum level and amount of dietary intake of calcium, phosphor, and 25-hydroxy vitamin D were measured.

Setting

A referral tertiary rehabilitation center in Iran.

Participants

Patients with SCI who had no previous history of endocrine disorders and were not on specific medications entered the investigation. Those with non-traumatic SCI, pregnant, or with substance dependency were excluded as well.

Interventions

No interventions were applied.

Main study outcome measures

Dual X-ray absorptiometry was performed to estimate BMD. Body mass index was positively associated with higher femoral (P < 0.01, r = 0.56) and hip (P < 0.0001, r = 0.82) BMD only in female participants. The high prevalence of vitamin D deficiency (60%) was noticeable.

Results

Older male patients revealed lower BMD only in spinal vertebrae (P < 0.02, r = −0.21). A significant higher BMD loss in lumbar vertebras in male patients with complete spinal cord lesion (P < 0.009) was detected. Spinal reduction of BMD was more severe when the level of injury was above T6 (P < 0.02).

Conclusion

Along with the clarification of age, gender, post injury duration, and the other factors'' effect on the BMD in the SCI patients, here we have also shown the noticeable prevalence of the 25-hydoxy vitamin D deficiency in these patients which needs attention.     

Factors related to caregiving for individuals with spinal cord injury compared to caregiving for individuals with other neurologic conditions

Context/objective

To compare outcomes among caregivers of adults with spinal cord injuries (SCIs) to caregivers of adults with other neurological conditions, and determine if caregiving for SCI is associated with poor health status and chronic conditions.

Design

Secondary data analysis of 2009/2010 Behavioral Risk Factor Surveillance System survey.

Participants

Informal caregivers of adults with neurological conditions.

Outcome measures

Sociodemographics, caregiving factors (e.g. role, emotional support, life satisfaction), lifestyle behaviors, chronic conditions, and health status.

Results

Demographics and lifestyle behaviors did not differ in caregivers of adults with SCI vs. caregivers of adults with other neurological conditions (except younger age of SCI caregivers). Greater proportions of caregivers of adults with SCI had coronary heart disease (CHD) (12% vs. 6%, P = 0.06) and were obese (43% vs. 28%, P = 0.03). Frequent physical distress was reported by 20% of caregivers of persons with SCI (vs. 12% of other caregivers, P = 0.09), but mental health did not differ between caregiver groups. A greater proportion of caregivers of adults with SCI experienced insufficient sleep (47% vs. 30%, P = 0.008) and more days without enough sleep (13 vs. 9 days, P = 0.008). Odds of being younger, caregiver of a spouse, having CHD, and being obese were associated with being a caregiver of an adult with SCI.

Conclusion

Caregivers of adults with SCI report similar mental health status, but more poor sleep, and have increased odds of CHD and obesity. Interventions to address physical distress, improve sleep, and address CHD and obesity are needed in this cohort.     

Associations with chest illness and mortality in chronic spinal cord injury

Objective

Identify factors associated with chest illness and describe the relationship between chest illness and mortality in chronic spinal cord injury (SCI).

Design

Cross-sectional survey assessing chest illness and a prospective assessment of mortality.

Methods

Between 1994 and 2005, 430 persons with chronic SCI (mean ± SD), 52.0 ± 14.9 years old, and ≥4 years post SCI (20.5 ± 12.5 years) underwent spirometry, completed a health questionnaire, and reported any chest illness resulting in time off work, indoors, or in bed in the preceding 3 years. Deaths through 2007 were identified.

Outcome measures

Logistic regression assessing relationships with chest illness at baseline and Cox regression assessing the relationship between chest illness and mortality.

Results

Chest illness was reported by 139 persons (32.3%). Personal characteristics associated with chest illness were current smoking (odds ratio =2.15; 95% confidence interval =1.25–3.70 per each pack per day increase), chronic obstructive pulmonary disease (COPD) (3.52; 1.79–6.92), and heart disease (2.18; 1.14–4.16). Adjusting for age, subjects reporting previous chest illness had a non-significantly increased hazard ratio (HR) for mortality (1.30; 0.88–1.91). In a multivariable model, independent predictors of mortality were greater age, SCI level and completeness of injury, diabetes, a lower %-predicted forced expiratory volume in 1 second, heart disease, and smoking history. Adjusting for these covariates, the effect of a previous chest illness on mortality was attenuated (HR = 1.15; 0.77–1.73).

Conclusion

In chronic SCI, chest illness in the preceding 3 years was not an independent risk factor for mortality and was not associated with level and completeness of SCI, but was associated with current smoking, physician-diagnosed COPD, and heart disease history.     

Testing the feasibility of training peers with a spinal cord injury to learn and implement brief action planning to promote physical activity to people with spinal cord injury

Objective

The present study tested the feasibility of training peers with spinal cord injury (SCI) to learn brief action planning (BAP), an application of motivational interviewing principles, to promote physical activity to mentees with SCI.

Method

Thirteen peers with SCI attended a half-day BAP workshop. Using a one-arm, pre-, post-test design, feasibility to learn BAP was assessed in terms of peers'' (1) BAP and motivational interviewing spirit competence; (2) training satisfaction; and (3) motivations to use BAP as assessed by measures of the theory of planned behavior constructs. Measures were taken at baseline, immediately post-training, and 1 month follow up.

Results

Following the training, participants'' BAP and motivational interviewing competence significantly increased (P''s < 0.05, d''s > 2.27). Training satisfaction was very positive with all means falling above the scale midpoint. Participants'' perceived behavioral control to use BAP increased from baseline to post (P < 0.05, d = 0.91) but was not maintained at follow up (P > 0.05).

Conclusion

Training peers with a SCI to learn to use BAP is feasible.

Practical implications

BAP is a tool that can be feasibly learned by peers to promote physical activity to their mentees.     

Satisfaction with upper extremity surgery in individuals with tetraplegia

Objective

To supplement the scant information available regarding the satisfaction of patients with tetraplegia following upper extremity reconstructive surgery for such individuals with spinal cord injury (SCI).

Study design

Retrospective study with questionnaire follow-up.

Setting

The Danish Spinal Cord Injury Centers.

Material and methods

In the initial review period, 119 upper extremity surgeries were performed on patients with tetraplegia (n = 49). Seven died and the remaining 42 were invited to complete a follow-up questionnaire with a five-level scale ranging from strongly agree to strongly disagree regarding satisfaction. Forty patients completed the questionnaire.

Results

Median time from first surgery was 13 years (2–36). Sixty-five percent of the sample had a C5–C6 SCI, with 64% experiencing complete injury. Initially, 76% of the sample expressed general satisfaction with life, but only 28% of the sample reported that hand appearance improved after surgery. Interestingly, those having surgery from 1991 to 2008 reported significantly greater satisfaction (P < 0.001) and were significantly more satisfied with activities of daily living (ADL) (P < 0.001) than those having surgery between the years 1973 and 1990. In particular, gain of independence was obtained with pinch/specific hand surgery compared to triceps activation. Accordingly, the pinch/specific hand surgery group was significantly more satisfied than the triceps group on the ADL (P = 0.027), and the independence questions (P < 0.001).

Conclusion

Overall satisfaction with upper extremity surgery is high. It can have a positive impact on life in general, ability to perform ADL, as well as supplying an increased level of independence.     

Influence of different rehabilitation therapy models on patient outcomes: Hand function therapy in individuals with incomplete SCI

Objectives

The primary objective was to compare the benefits of single (COT1) versus double (COT2) dose of conventional occupational therapy (COT) in improving voluntary hand function in individuals with incomplete, sub-acute C3–C7 spinal cord injury (SCI). The secondary objective was to compare these two interventions versus functional electrical stimulation therapy plus COT (FES + COT).

Design

Retrospective analysis.

Setting

Inpatient spinal cord rehabilitation center, Toronto.

Participants

Individuals with traumatic incomplete sub-acute SCI.

Interventions

Data from Phases I and II (ClinicalTrials.gov ID {"type":"clinical-trial","attrs":{"text":"NCT00221117","term_id":"NCT00221117"}}NCT00221117) randomized control trials were pooled together for the purpose of this study. Participants in the COT1 group received 45 hours of therapy, the COT2 group received 80 hours of therapy, and the FES + COT group received 40 hours of COT therapy +40 hours of FES therapy.

Outcome measures

We analyzed the functional independence measure (FIM) and the spinal cord independence measure (SCIM) self-care sub-scores.

Results

The mean change scores on the FIM self-care sub-score for the COT1, COT2, and FES + COT groups were 12.8, 10, and 20.1 points, respectively. Similarly, the mean change scores on the SCIM self-care sub-score for the COT1, COT2, and FES + COT groups were, 2.6, 3.16, and 10.2 points, respectively.

Conclusion

Increased rehabilitation intensity alone may not always be beneficial. The type of intervention plays a significant role in determining functional changes. In this instance, receiving one (COT1) or two (COT2) doses of COT resulted in similar outcomes, however, FES + COT therapy yielded much better outcomes compared to COT1 and COT2 interventions.
