Abstract

Lannin NA, Horsley SA, Herbert R, McCluskey A, Cusick A. Splinting the hand in the functional position after brain impairment: a randomized, controlled trial. Arch Phys Med Rehabil 2003;84:297-302. 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[mdash ]motor training for upper-limb use and upper-limb stretches[mdash ]5 days a week. The experimental group also wore an immobilizing hand splint in the functional position (10[deg ][ndash ]30[deg ] 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[deg ] (95% confidence interval [CI], [minus ]7.2[deg ] to 3.2[deg ]), function favored controls by 0.2 points (95% CI, [minus ]2.7 to 2.3), and pain favored the experimental group by 1cm (95% CI, [minus ]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.

    Pooled analysis was not possible because of the heterogeneity of methods used across studies. Five of the studies measured joint angle at a standardized torque [7–9,42,43]. At the shoulder, the study of Turton and Britton [7] did not report changes in ROM at 1 kg of stretching (8 weeks; volume 2.5 hr/week; −1° [95% confidence interval (CI) −15° to 13°] in favour of stretching).
