Effects of splinting on wrist contracture after stroke: a randomized controlled trial.

BACKGROUND AND PURPOSE: Splints are commonly applied to the wrist and hand to prevent and treat contracture after stroke. However, there have been few randomized trials of this intervention. We sought to determine whether wearing a hand splint, which positions the wrist in either a neutral or an extended position, reduces wrist contracture in adults with hemiplegia after stroke. METHODS: Sixty-three adults who had experienced a stroke within the preceding 8 weeks participated. They were randomized to either a control group (routine therapy) or 1 of 2 intervention groups (routine therapy plus splint in either a neutral or an extended wrist position). Splints were worn overnight for, on average, between 9 and 12 hours, for 4 weeks. The primary outcome, measured by a blinded assessor, was extensibility of the wrist and long finger flexor muscles (angle of wrist extension at a standardized torque). RESULTS: Neither splint appreciably increased extensibility of the wrist and long finger flexor muscles. After 4 weeks, the effect of neutral wrist splinting was to increase wrist extensibility by a mean of 1.4 degrees (95% CI, -5.4 degrees to 8.2 degrees), and splinting the wrist in extension reduced wrist extensibility by a mean of 1.3 degrees (95% CI, -4.9 degrees to 2.4 degrees) compared with the control condition. CONCLUSIONS: Splinting the wrist in either the neutral or extended wrist position for 4 weeks did not reduce wrist contracture after stroke. These findings suggest that the practice of routine wrist splinting soon after stroke should be discontinued.

Fitting back in: adolescents returning to school after severe acquired brain injury.

PURPOSE: To explore the experiences of Australian adolescents with severe acquired brain injury (ABI) and their families as the adolescent returned to school. In particular, to understand the influence of services and support on the school return. METHOD: In-depth interviews conducted over a two-year period with families who had an adolescent with a recent severe ABI (mean age 15 years, 11 months) analysed using a grounded theory approach. RESULTS: Two critical phases for adolescents returning to school post ABI were identified: organizing the school return and being back at school. Experience in these phases was influenced by length of school absence, extent of noticeable and hidden problems and school response to the students' return post injury. The central concept characterizing experience was the challenge of fitting back in. Some adolescents fitted back in adequately and continued school participation. Those that did not fit in tried again by revisiting the organizing phase, re-evaluated their school experience and either continued or left school. CONCLUSIONS: Adolescents with ABI faced the challenge of fitting back in when they returned to school. This was either facilitated or hindered by the extent and quality of organization, communication and support from parents, schoolteachers and the rehabilitation team.

Low-dose/high-concentration localized botulinum toxin A improves upper limb movement and function in children with hemiplegic cerebral palsy.

The objective was to determine the effects of low-dose, high-concentration, dual localized botulinum toxin A (BTX-A) injections on upper limb movement quality and function. Study design was an evaluator-blinded, randomized, controlled trial. Forty-two children (31 males, 11 females; range 2-8y, mean 4y [SD 1.6]) with hemiplegic cerebral palsy (Gross Motor Function Classification System level I) participated. All received occupational therapy. The treatment group (n=21) received one injection series (mean muscles injected 6 [SD 1.05]; total dose 82-220 units, mean 139 [SD 37.48]; dilution 100 units/0.5ml). Primary outcome of Quality of Upper Extremity Skills Test (QUEST) at 6 months was not significant (p=0.318). Secondary outcomes were average treatment effects at 1, 3, and 6 months, which favoured the treatment group: QUEST (p<0.001); Canadian Occupational Performance Measure (performance, p=0.002; satisfaction p=0.007); parent Goal Attainment Scaling (GAS; p=0.001), therapist GAS (p<0.001); Pediatric Evaluation of Disability Inventory (PEDI) functional skills (p=0.030); Ashworth (p<0.001). PEDI caregiver assistance was not significant (p=0.140). Therapy alone is effective, but at 1 and 3 months movement quality is better where BTX-A is also used. Moreover, function is better at 1, 3, and 6 months, suggesting BTX-A enhances therapy outcomes beyond the pharmacological effect. One- and 3-month Ashworth and QUEST scores suggest precise needle placement accuracy.

Effect of rater training on reliability of Melbourne Assessment of Unilateral Upper Limb Function scores.

The aim of this study was to explore the effect of rater training on interrater reliability, internal consistency, standard error of measurement, and rater familiarity for the Melbourne Assessment of Unilateral Upper Limb Function. Twenty-four participants (raters) were randomly assigned to either 'trained' (n=12) or 'untrained' (n=12) interventions; they then scored the same nine video recordings of children completing the instrument. The age range of the children was 5 years 5 months to 12 years; there were six males, three females, all with spastic cerebral palsy (five with quadriparesis and four with hemiparesis); Gross Motor Function Classification System levels were I (n=3), II (n=3), III (n=1), and IV (n=2). All participants were novice occupational therapists and had no previous experience of using the instrument. A significant difference in perceived test familiarity was found after scoring but not before: trained raters scored higher. A significant difference in total scores for all cases was found and in eight of 16 individual item total raw scores. Again, trained raters scored higher. Interrater reliability was high in both groups, except item 6 (untrained). Internal consistency was high in both groups, except items 6 and 9 (untrained). We conclude that training for novice users increases familiarity and results in raters' perceiving higher levels of performance in some items. The Melbourne Assessment has high reliability even for novice users.

Splinting the hand in the functional position after brain impairment: a randomized, controlled trial.

OBJECTIVE: To evaluate the effects of 4 weeks of hand splinting on the length of finger and wrist flexor muscles, hand function, and pain in people with acquired brain impairment. DESIGN: Randomized, assessor-blinded trial. SETTING: Rehabilitation center in Australia. PARTICIPANTS: Twenty-eight adults with acquired brain impairment, all within 6 months of the first injury. There was 1 withdrawal. INTERVENTIONS: Subjects in both experimental (n=17) and control (n=11) groups participated in routine therapy-motor training for upper-limb use and upper-limb stretches-5 days a week. The experimental group also wore an immobilizing hand splint in the functional position (10 degrees -30 degrees wrist extension) for a maximum of 12 hours each night for the duration of the 4-week intervention period. MAIN OUTCOME MEASURES: The length of the wrist and extrinsic finger flexor muscles was evaluated by measuring the torque-controlled range of wrist extension with the fingers extended. Functional hand use was evaluated with the Motor Assessment Scale. Pain was evaluated with a visual analog scale. RESULTS: The effects of splinting were statistically nonsignificant and clinically unimportant. At follow-up, estimates of treatment effects slightly favored the control group: range of motion at the wrist favored controls by 2 degrees (95% confidence interval [CI], -7.2 degrees to 3.2 degrees ), function favored controls by 0.2 points (95% CI, -2.7 to 2.3), and pain favored the experimental group by 1cm (95% CI, -4.6 to 2.2). CONCLUSIONS: An overnight splint-wearing regimen with the affected hand in the functional position does not produce clinically beneficial effects in adults with acquired brain impairment.

Factors affecting patient recruitment in an acute rehabilitation randomized controlled trial.

OBJECTIVE: To evaluate factors associated with randomized controlled trial patient recruitment by therapists. METHOD: Survey of 18 (of a possible 26) therapists who had agreed to recruit patients for a randomized controlled trial (78% response rate). RESULTS: Sixteen respondents had enrolled at least one patient. The site at which the therapist worked neither influenced the likelihood that a therapist would contact the researcher nor influenced the recruitment rate. Seventeen respondents reported that they contacted the researcher to discuss one or more of their patients for potential inclusion in the trial. Factors reported by therapists as reasons why they did not recommend the trial to eligible patients were not specific to study inclusion or exclusion criteria, rather were linked to personal judgments about patient suitability for the study. Regression analysis indicated that being enrolled or having completed master's level postgraduate studies, and choosing not to refer patients because of concern for their poor medical prognosis were the only factors that significantly influenced recruitment rate (p < 0.001). CONCLUSION: Recruitment practices vary amongst therapists. Selection of therapists with postgraduate qualifications as recruiters may be an effective way to enhance recruitment rate.
