Acupuncture for upper-extremity rehabilitation in chronic stroke: a randomized sham-controlled study

OBJECTIVE: To compare the effects of traditional Chinese acupuncture with sham acupuncture on upper-extremity (UE) function and quality of life (QOL) in patients with chronic hemiparesis from stroke. DESIGN: A prospective, sham-controlled, randomized controlled trial (RCT). SETTING: Patients recruited through a hospital stroke rehabilitation program. PARTICIPANTS: Thirty-three subjects who incurred a stroke 0.8 to 24 years previously and had moderate to severe UE functional impairment. INTERVENTIONS: Active acupuncture tailored to traditional Chinese medicine diagnoses, including electroacupuncture, or sham acupuncture. Up to 20 treatment sessions (mean, 16.9) over a mean of 10.5 weeks. MAIN OUTCOME MEASURES: UE motor function, spasticity, grip strength, range of motion (ROM), activities of daily living, QOL, and mood. All outcomes were measured at baseline and after treatment. RESULTS: Intention-to-treat (ITT) analyses found no statistically significant differences in outcomes between active and sham acupuncture groups. Analyses of protocol-compliant subjects revealed significant improvement in wrist spasticity (P<.01) and both wrist (P<.01) and shoulder (P<.01) ROM in the active acupuncture group, and improvement trends in UE motor function (P=.09) and digit ROM (P=.06). CONCLUSIONS: Based on ITT analyses, we conclude that acupuncture does not improve UE function or QOL in patients with chronic stroke symptoms. However, gains in UE function observed in protocol-compliant subjects suggest traditional Chinese acupuncture may help patients with chronic stroke symptoms. These results must be interpreted cautiously because of small sample sizes and multiple, unadjusted, post hoc comparisons. A larger, more definitive RCT using a similar design is feasible and warranted.     

Effects of ankle-foot orthoses on ankle and foot kinematics in patient with ankle osteoarthritis

OBJECTIVE: To determine if different foot orthoses have a similar effect on foot kinematics in subjects with ankle osteoarthritis (OA) when walking on various ground conditions. DESIGN: Within-subject comparisons study. SETTING: Biomechanics research laboratory. PARTICIPANTS: Thirteen subjects with unilateral ankle OA. INTERVENTIONS: Custom-made ankle-foot orthosis (AFO), rigid hindfoot orthosis (HFO-R), and articulated hindfoot orthosis (HFO-A) were used by subjects when walking on level, ascending and descending ramp, and side-slope conditions. MAIN OUTCOME MEASURES: The range of motion of the hindfoot (calcaneus relative to tibia) and forefoot (metatarsal relative to calcaneus) was measured using an 8-camera motion analysis system. RESULTS: The AFO and HFO-R provided the best sagittal plane hindfoot motion restriction over all ground conditions (P<.001). The HFO-R allowed the greatest sagittal plane forefoot motion when walking over level (P=.01) and side-slope (P<.02) conditions, the greatest frontal plane forefoot motion walking down the ramp (P=.003), and the greatest transverse plane forefoot motion when walking over level (P=.011) and ramp-ascending conditions (P=.005). The HFO-A restricted motion of the unaffected joint and did not effectively restrict hindfoot motion. CONCLUSIONS: The HFO-R not only provides selective restriction to the ankle-hindfoot motion, but also allows sufficient forefoot motion compared with the AFO. We consider the HFO-R to be the best option of all tested orthoses for treating patients with ankle OA pain arising from ankle motion.     

Exploring poststroke mood changes in community-dwelling stroke survivors: a qualitative study

White JH, Magin P, Attia J, Pollack MR, Sturm J, Levi CR. Exploring poststroke mood changes in community-dwelling stroke survivors: a qualitative study.

Objective

To explore the long-term experience of mood changes in community-dwelling stroke survivors at 1, 3, and 5 years after stroke.

Design

A qualitative study using a modified grounded theory approach. The primary data collection method was semi-structured interviewing.

Setting

Community-dwelling stroke survivors in metropolitan Newcastle, NSW, Australia.

Participants

Twelve community-dwelling stroke survivors (6 men, 6 women; age range 43−92y; 4 participants from each cohort) discharged from a tertiary referral hospital.

Interventions

Not applicable.

Main Outcome Measures

Qualitative outcomes were participants' perceptions using in-depth, semi-structured interviews with participants from 3 community-based cohorts of stroke survivors at 1, 3, and 5 years poststroke.

Results

Four main categories of mood change were described by participants including feelings of frustration, reduced self-efficacy, dependency, and loss. Factors that modulated these mood changes included the presence or absence of insight, hope for the future, faith, and support. A modified grounded theory approach was used for data analysis using a process of constant comparison.

Conclusions

Mood changes continued well beyond discharge and in some cases commenced after discharge in this sample of stroke survivors. Use of qualitative methodology extends our understanding of the extent and nature of low mood after stroke. There is a need for enhanced services to monitor and address low mood.     

Feedback-controlled and programmed stretching of the ankle plantarflexors and dorsiflexors in stroke: effects of a 4-week intervention program

OBJECTIVE: To investigate the effect of repeated feedback-controlled and programmed "intelligent" stretching of the ankle plantar- and dorsiflexors to treat subjects with ankle spasticity and/or contracture in stroke. DESIGN: Noncontrolled trial. SETTING: Institutional research center. PARTICIPANTS: Subjects with spasticity and/or contracture after stroke. INTERVENTIONS: Stretching of the plantar- and dorsiflexors of the ankle 3 times a week for 45 minutes during a 4-week period by using a feedback-controlled and programmed stretching device. MAIN OUTCOME MEASURES: Passive and active range of motion (ROM), muscle strength, joint stiffness, joint viscous damping, reflex excitability, comfortable walking speed, and subjective experiences of the subjects. RESULTS: Significant improvements were found in the passive ROM, maximum voluntary contraction, ankle stiffness, and comfortable walking speed. The visual analog scales indicated very positive subjective evaluation in terms of the comfort of stretching and the effect on their involved ankle. CONCLUSIONS: Repeated feedback-controlled or intelligent stretching had a positive influence on the joint properties of the ankle with spasticity and/or contracture after stroke. The stretching device may be an effective and safe alternative to manual passive motion treatment by a therapist and has potential to be used to repeatedly and regularly stretch the ankle of subjects with spasticity and/or contracture without daily involvement of clinicians or physical therapists.     

The effect of heat on tissue extensibility: a comparison of deep and superficial heating

OBJECTIVE: To compare the effects of deep heating (shortwave diathermy [SWD]) and superficial heating (hydrocollator packs) on tissue extensibility. DESIGN: A double-blind, repeated-measures study. Possible effects of sex and intervention order were controlled. SETTING: A clinical laboratory. PARTICIPANTS: Twenty-four subjects with no neurologic or musculoskeletal pathologies affecting their lower limbs. INTERVENTIONS: Three intervention conditions: deep heating (SWD), superficial heating (hot packs), and no heating were applied in preallocated order to each subject at least 36 hours apart. MAIN OUTCOME MEASURES: Ankle dorsiflexion in weight bearing was measured by using an inclinometer to ascertain changes in the extensibility of the calf muscles and associated soft tissues. RESULTS: Deep heating increased the range of ankle dorsiflexion by 1.8 degrees +/-1.9 degrees . The change in ankle dorsiflexion after superficial and no heating was 0.7 degrees +/-1.5 degrees and -0.1 degrees +/-1.0 degrees , respectively. CONCLUSIONS: Deep heating, in the absence of stretching, increases tissue extensibility more than superficial heating or no heating. Superficial heating is more effective than no heating, but the difference was not statistically significant.     

Effect of heat in increasing the range of knee motion after the development of a joint contracture: an experiment with an animal model

OBJECTIVE: To compare the effects of 2 different heat modalities, infrared and ultrasonic therapy, on a knee flexion contracture. DESIGN: In vivo, experimental, controlled study involving a rat knee joint contracture model that was immobilized using a ligature in flexion for 40 days. SETTING: Collegiate research laboratory. ANIMALS: Ninety-three adult male Wistar rats. INTERVENTIONS: After remobilization, rats were assigned to 3 treatment groups: stretching only (S), stretching with infrared therapy (S+IR), and stretching with ultrasonic therapy (S+US). Six treatment sessions were given in 2 weeks. MAIN OUTCOME MEASURES: The angle of maximum knee extension, wet-weight of triceps surae muscles, phase lag, and dynamic stiffness as mechanical responses were measured, and histologic study was conducted. RESULTS: Compared with the S group, both the S+IR and S+US groups exhibited a significant increase in range of motion (ROM) (P=.021, P=.008, respectively) and a tendency to decrease the phase lag, but there was no significant difference between the 2 heat-combined groups. There were no differences in the weights of the triceps surae muscles and in dynamic stiffness among the groups. CONCLUSIONS: Six treatment sessions of stretching with infrared or ultrasound were more effective than stretching without heat at increasing the ROM and decreasing the phase lag of a moderately severe joint contracture. The clinical implementation of heat is advocated to regain a normal ROM and mechanical property when experiencing a joint contracture.     

Validity of the Fingertip-To-Floor Test and Straight Leg Raising Test in Patients With Acute and Subacute Low Back Pain: A Comparison by Sex and Radicular Pain

Ekedahl KH, Jönsson B, Frobell RB. Validity of the fingertip-to-floor test and straight leg raising test in patients with acute and subacute low back pain: a comparison by sex and radicular pain.

Objective

To use self-reported disability (Roland-Morris Disability Questionnaire [RMDQ]) to assess the criterion validity of straight leg raising (SLR) test and flexion range of motion (ROM) (fingertip-to-floor test) before and after stratification by sex and presence/absence of radicular pain.

Design

Cross-sectional study.

Setting

Outpatient physical therapy clinic.

Participants

Subjects with acute/subacute low back pain with (n=40) and without (n=35) radicular pain.

Interventions

Not applicable.

Main Outcome Measures

We examined the relationship between RMDQ (reference variable) and SLR test and fingertip-to-floor test. The sample was stratified by presence/absence of radicular pain (categorized by the dichotomous slump test).

Results

In the entire sample, fair correlations were found between both physical impairment tests (ie, SLR test and flexion ROM) and self-reported disability (.27<r>.44). After stratification by sex, the correlation between RMDQ and flexion ROM and between RMDQ and nonside-specific SLR test increased in women but decreased in men. In those with radicular pain, good correlations were found between RMDQ and flexion ROM (r=.68 for men and r=.70 for women), and moderate correlation was found between the RMDQ and SLR tests of the affected side in women (r=.60), but only fair correlation was found between the RMDQ and SLR tests of the affected side in men (r=.28).

Conclusions

After stratification by sex and presence/absence of radicular pain, the present study supports a good validity of the fingertip-to-floor test for both men and women with radicular pain. The SLR test, however, was of less value as an indicator of self-reported disability after stratification, especially for men.     

Improvement in walking speed in poststroke spastic hemiplegia after intrathecal baclofen therapy: a preliminary study

OBJECTIVE: To explore whether intrathecal baclofen (ITB) therapy improves ambulation in stroke survivors. DESIGN: Case series. SETTING: Tertiary care center. PARTICIPANTS: Ten adults with poststroke hemiparesis who were ambulatory at the time of pump implantation. INTERVENTIONS: Implantation of ITB pump after inadequate control of spasticity with other interventions. Time from stroke onset to implantation averaged 28.6 months (range, 9-55mo). MAIN OUTCOME MEASURES: Customary walking speed was measured from the time required to walk 50ft (15m) at a self-selected pace. Evaluators rated spastic hypertonia and functional mobility. RESULTS: Statistically significant improvements occurred in walking speed, functional mobility ratings, and spasticity (P<.05) at a follow-up interval that averaged 8.9 months. Mean walking speed over 50ft improved from 36.6 to 52cm/s. Mean Modified Ashworth Scale scores in the muscles of the affected lower limb improved from 2.0 to 0.4. Normal muscle strength (5/5) was preserved in the unaffected limbs. CONCLUSIONS: This preliminary study suggests that ITB therapy, in combination with physical therapy, may improve walking speed and functional mobility in ambulatory individuals with poststroke spastic hemiplegia.     

Prediction of social activity 1 year poststroke

OBJECTIVE: To develop an easy-to-use prediction rule for social activity 1 year poststroke that can identify patients at risk for social inactivity. DESIGN: Inception cohort. SETTING: Rehabilitation center. PARTICIPANTS: Patients with a first-ever supratentorial stroke were selected in 4 Dutch rehabilitation centers. Data of 250 patients were available for analysis. Potential prognostic factors measured at admission were sex, age, marital status, prestroke employment status, educational level, type of stroke, hemisphere, motor impairment, trunk control, communication, and activities of daily living (ADL) dependency. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURE: Social activity measured by the Frenchay Activities Index (FAI) at 1 year poststroke. RESULTS: Multivariate backward linear regression analysis identified sex, age, marital status, motor impairment, communication, and ADL dependency as important predictors of the FAI score 1 year poststroke. An easy-to-use score chart was constructed that could identify patients at risk for social inactivity. The score chart proved to be well able to discriminate poor social functioning from moderate to good social functioning (area under the curve = .85). CONCLUSIONS: Identifying patients at risk enables health care professionals to focus on the social activity of this patient subgroup at an early stage in the care process.     

Isometric osteopathic manipulation influences on cervical ranges of motion and correlation with osteopathic palpatory diagnosis: A randomized trial

IntroductionIsometric manipulation is a current practice in osteopathy and treatment benefits have been reported in the literature. Such benefits could be assessed using experimental non-invasive cervical mobility measurements. The main objective was to quantitatively measure the effects of isometric manipulation on principal and compensatory cervical motions.Methods101 healthy volunteers were included in this study. 51 healthy volunteers selected randomly underwent the experimental protocol before and after isometric treatment and were compared to 50 healthy volunteers who underwent a placebo treatment. Osteopathic diagnosis was performed on each healthy volunteer before and after the treatment. The experimental protocol included measurements by a motion capture system focusing on principal range of motion and compensatory motions.ResultsIn both the isometric and the placebo sample, respectively including 51 (age: 29.2 ± 8.1, BMI: 22.2 ± 3.5) and 50 healthy volunteers (age: 27.4 ± 6.8, BMI: 22.9 ± 2.8), a pre-treatment diagnosis revealed a light cervical dysfunction in all subjects, mainly in levels C3 and C4. Altered ranges of motion thresholds (C3/C4 alterations) were identified: 113.2° for flexion, 130.0° for rotation and 90.2° for lateral flexion.After manipulations, the volunteers who underwent the isometric treatment presented a slight increase in amplitude for lateral flexion (p < 0.04), which was not found in the volunteers who underwent the placebo treatment. Compensatory motions showed differences pre and post isometric treatment without reaching significant values.ConclusionPrincipal ranges of motion were found significantly higher after osteopathic treatment when compared to the placebo treatment. Osteopathic palpatory diagnosis showed significant correlation with range of motions before treatment.     

Tongue-based biofeedback for balance in stroke: results of an 8-week pilot study

Badke MB, Sherman J, Boyne P, Page S, Dunning K. Tongue-based biofeedback for balance in stroke: results of an 8-week pilot study.

Objective

To assess balance recovery and quality of life after tongue-placed electrotactile biofeedback training in patients with stroke.

Design

Prospective multicenter research design.

Setting

Outpatient rehabilitation clinics.

Participants

Patients (N=29) with chronic stroke.

Interventions

Patients were administered 1 week of therapy plus 7 weeks of home exercise using a novel tongue based biofeedback balance device.

Main Outcome Measures

The Berg Balance Scale (BBS), Timed Up and Go (TUG), Activities-Specific Balance Confidence (ABC) Scale, Dynamic Gait Index (DGI), and Stroke Impact Scale (SIS) were performed before and after the intervention on all subjects.

Results

There were statistically and clinically significant improvements from baseline to posttest in results for the BBS, DGI, TUG, ABC Scale, and some SIS domains (Mobility, Activities of Daily Living/Instrumental Activities of Daily Living, Social, Physical, Recovery domains). Average BBS score increased from 35.9 to 41.6 (P<.001), and DGI score, from 11.1 to 13.7 (P<.001). Time to complete the TUG decreased from 24.7 to 20.7 seconds (P=.002). Including the BBS, DGI, TUG, and ABC Scale, 27 subjects improved beyond the minimal detectable change with 95% certainty (MDC-95) or minimal clinically important difference (MCID) in at least 1 outcome and 3 subjects improved beyond the MDC-95 or MCID in all outcomes.

Conclusions

Electrotactile biofeedback seems to be a promising integrative method to balance training. A future randomized controlled study is needed.     

Muscle strength and flexibility characteristics of people displaying excessive medial knee displacement

Bell DR, Padua DA, Clark MA. Muscle strength and flexibility characteristics of people displaying excessive medial knee displacement.

Objective

To determine differences in strength and range of motion (ROM) between participants who exhibit medial knee displacement (MKD) during a squat that is corrected by a heel lift and those who do not.

Design

Case control.

Setting

Sports medicine research laboratory.

Participants

Thirty-seven healthy subjects (control, 19; MKD, 18) with no lower-extremity injury in the past 6 months volunteered to participate.

Interventions

Not applicable.

Main Outcome Measures

Peak force was measured in newtons using a hand-held dynamometer and passive ROM was measured in degrees with a goniometer. Separate multivariate analyses of variance were used to determine differences in strength and ROM between groups. Post hoc testing was used to elucidate differences between groups.

Results

The MKD group had the following: greater hip external rotation strength (P=.03), increased hip extension strength (P=.01), less plantarflexion strength (P=.007), and increased hip external rotation ROM (P=.008).

Conclusions

The MKD group exhibited tight and weak ankle musculature. Interventions focusing on improving strength and ROM of the ankle may improve kinematics during a squat.     

Interobserver reproducibility of the visual estimation of range of motion of the shoulder

OBJECTIVES: To assess interobserver reproducibility (agreement and reliability) of visually estimated shoulder range of motion (ROM) and to study the influence of clinical characteristics on the reproducibility. DESIGN: Test-retest analyses. SETTING: Various health care settings in the Netherlands. PARTICIPANTS: Consecutive patients with shoulder complaints (N = 201) referred by 20 general practitioners, 2 orthopedic physicians, and 20 rheumatologists. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Independent visual estimation by 2 physiotherapists of the ROM. Agreement was calculated as the mean difference in visual estimation between examiners +/-1.96 x standard deviations of this mean difference. The intraclass correlation coefficient (ICC) was calculated as a measure of reliability, based on a 2-way random effects analysis of variance. RESULTS: The lowest level of agreement was for visual estimation of active and passive elevation (limits of agreement, -43.4 to 39.8 and -46.7 to 41.5, respectively, for the difference between the affected and contralateral sides), for which the level of agreement was most clearly associated with pain severity and disability. The ability to differentiate between subjects was acceptable for all movements for the difference between the affected and contralateral sides (ICCs, > .70) except for horizontal adduction (ICC = .49). CONCLUSIONS: Interobserver agreement was low for the assessment of active and passive elevation, especially for patients with a high pain severity and disability. Except for horizontal adduction, visual estimation seems suitable for distinguishing differences between affected and contralateral ROM between subjects.     

Effect of passive stretch on reproducibility of hip range of motion measurements

OBJECTIVE: To examine the intra- and intertester and intra- and interday reliability of hip passive range of motion (PROM) measurements and the effect of passive stretch on the reproducibility of PROM measurements. DESIGN: Reliability study. SETTING: Rehabilitation clinic at university hospital. PARTICIPANTS: Twenty volunteers (12 women, 8 men; age range, 18-45 y). INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Two physical therapists made 2 PROM measurements on the first day and repeated them once after 2 days. The PROM in hip flexion, extension, and inner rotation and knee flexion were determined. The measurements of the hip flexion and inner rotation involved either 1 or 8 short-term passive stretches. The reproducibility was expressed as the intraclass correlation coefficient (ICC) and the coefficient of variation (CV) (in percent). RESULTS: The passive stretch increased significantly ( P <.05 to P <.001) the PROM of the hip joint. The reproducibility of the PROM measurement did not increase after repetitive passive stretch. The intra- and interday intra- and intertester ICC and CV of the PROM of the hip flexion and hip inner rotation ranged from .655 to .988 and 2.1% to 12.6%, respectively. The intra- and intertester intra- and interday ICC of the PROM of the hip extension ranged from .740 to .961, and the CV ranged from -85.5% to 242.6%. The intra- and intertester intra- and interday ICC of the PROM of the knee flexion ranged from .497 to .913, and the CV ranged from 2.5% to 9.9%. CONCLUSIONS: Repetitive stretching increased significantly the PROM in hip flexion and inner rotation, but the reproducibility of the PROM measurement did not improve. The hip flexion and the hip inner rotation PROM measurements had moderate to very high intra- and interday intra- and intertester reliabilities. The reliability of the PROM in hip extension and knee flexion was poor.     

Range of motion in the upper and lower cervical spine in people with chronic neck pain

Reduced cervical range of motion (ROM) is a common finding in people with neck pain. With few exceptions, only the angle between head and thorax has been measured. Our aim was to use an extended model to compare active cervical flexion and extension, separate for upper and lower cervical levels, between people with chronic non-traumatic neck pain and controls. We also investigated associations between ROM measures, symptoms and self-rated functioning.In this cross-sectional study, 102 subjects with neck pain and 33 healthy controls participated. An electromagnetic tracker system was used to measure the kinematics to construct a three-segment model including the thorax, cervical spine and head. Neutral flexion/extension were defined at subjects’ self-selected seated posture.We found that in the neck pain group, extension in the upper cervical levels and predominately flexion for the lower levels were reduced. The ratio between ROM for the upper and lower levels was altered in the neck pain group so that the lower levels contributed to a lesser extent to the total sagittal ROM compared to controls. These findings could not be explained by a greater forward head posture but must have other origins. For the neck pain group, ROM measures were weakly associated to pain and self-rated functioning. Altogether, this implies that using a three-segment model for assessment of ROM can be a valuable improvement for characterisation of patients and treatment evaluation.     

Effects of intensive arm training with an electromechanical orthosis in chronic stroke patients: a preliminary study

de Araújo RC, Junior FL, Rocha DN, Sono TS, Pinotti M. Effects of intensive arm training with an electromechanical orthosis in chronic stroke patients: a preliminary study.

Objectives

To evaluate the use of an electromechanical device, comprising an exoskeleton, a static orthosis, and a glove, for functional rehabilitation of the elbow and hand in patients with hemiparesis, and to compare it with physical therapy rehabilitation.

Design

Pretest-posttest design.

Setting

Rehabilitation laboratory.

Participants

Volunteer sample of persons (N=12) with persistent hemiparesis from a single, unilateral stroke within the past 3 to 36 months.

Interventions

The volunteers were randomly divided into 2 groups. One group was treated with a conventional program of physiotherapy, and another group participated in a training program in which an electromechanical orthosis was used. All volunteers received 24 sessions, held 3 times a week for 8 weeks.

Main Outcome Measures

Modified Ashworth Scale (MAS), Fugl-Meyer Assessment (FMA), and electromyogram (EMG) amplitude.

Results

No statistical difference was found in the initial and final values of the MAS. Both groups showed a significant increase for the total scores of the FMA. However, only the group treated with the orthosis showed an increase in FMA scores related to the wrist and hand joint. The EMG analysis showed increased EMG amplitudes for all muscles in the group treated with the orthosis, whereas the group treated with physiotherapy showed gains in electromyographic activity only in the extensor digitorum communis. Intergroup comparison showed that the initial FMA scores of the wrist/hand were higher in the group treated with physiotherapy. However, after training, the scores in the group that used the orthosis were equivalent to those of the physiotherapy group.

Conclusions

The results suggest that this device can be an auxiliary tool to help the conventional rehabilitation program of motor function of the affected upper extremity.     

Shoulder pain, range of motion, and functional motor skills after acute tetraplegia

OBJECTIVES: To investigate (1) the prevalence and course of shoulder pain in acute tetraplegia and (2) its relationship with range of motion (ROM) and function and any associated risk factors. DESIGN: A longitudinal prospective study. SETTING: Spinal injury unit in an Australian hospital. PARTICIPANTS: Inpatients with acute tetraplegia. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Demographics, pain intensity, shoulder ROM, and functional motor skills. RESULTS: The prevalence of pain during rehabilitation was 85%. Risk factors associated with pain during rehabilitation included age less than 30 years or more than 50 years (F=8.892, P=.064), admission motor level at C2-5 (F=5.833, P=.016), admission sensory level at C2-5 (F=7.543, P=.006), lower left upper limb (P=.005; 95% confidence interval [CI], -14.74 to -2.86) and total American Spinal Injury Association motor scores (P=.009; 95% CI, -29.53 to -4.67), and a shorter duration of bedrest (F=5.794, P=.055). Subjects with pain lost ROM in left abduction (P=.038; 95% CI, -25.9 to -0.9) and right abduction (P=.05; 95% CI, -30 to 9.3). No relationship existed between shoulder pain and functional motor skills on discharge. CONCLUSION: Shoulder pain is common in acute tetraplegia and is associated with loss of shoulder ROM. Risk factors identified include age, injury level, and duration of bedrest. Areas for further study are identified.     

Inter- and intrarater reliability of a back range of motion instrument

OBJECTIVE: To examine the interrater and intrarater reliability of a back range of motion (BROM) instrument when measuring lumbar spine active planar motions and pelvic inclination. DESIGN: Single-group repeated measures for inter- and intrarater reliability. SETTING: Academic institution. PARTICIPANTS: Ninety-one participants (61 women, 30 men; mean age, 28 y) without a current complaint of low back pain volunteered. INTERVENTION: Two examiners measured pelvic inclination and all lumbar motions by using the BROM device. Subjects alternated between examiners for 4 complete trials; examiners remained blinded to the measurements. MAIN OUTCOME MEASURES: Intraclass correlation coefficients (ICCs) were used to determine intrarater and interrater reliability. Regression analysis was performed to determine the role palpation played in sagittal plane measurement error. RESULTS: Intrarater reliability for side bending was good (ICC range, .85-.83), lumbar forward flexion and pelvic inclination was good to fair (ICC range, .84-.79), and extension and rotation was fair to poor (ICC range, .76-.58). Interrater reliability was fair to poor for all lumbar motions and for pelvic inclination (ICC range, .79-.55). Less than 2% of the variation in sagittal plane measurements was explained by consistency of palpation for device placement. CONCLUSIONS: The BROM provides a reliable means of measuring lumbar forward flexion, side bending, and pelvic inclination when performed by the same examiner in asymptomatic subjects.
