Task-Specific Training With Trunk Restraint on Arm Recovery in Stroke


Phase N/A Results

Trial Description

To determine whether task-specific training with trunk-restraint (TR) produces greater improvements in arm impairment and function than training without TR in patients with chronic hemiparesis.


Trial Design

Randomized, controlled, double-blind trial.

Patient Involvement

Participants were stratified with Fugl-Meyer (FM) Arm scores to less (FM>/=50) or more severe (FM <50)strata and randomly assigned by a research assistant to experimental (TR) or control (nonrestraint, C) groups resulting in 7 and 8 patients in less (mild) and more severe (moderate) strata respectively per group. Participants received a 1-hour therapist-supervised home program with object-related reach-to-grasp training 3 times per week for 5 weeks. Both groups practiced the same tasks except that in TR, trunk movements (sagittal displacement, rotation) were prevented by body and shoulder belts attached to the chairback. Scapular elevation/protraction was not restricted. Group C wore unfastened belts without limiting trunk movements. Evaluations were repeated before, immediately after, and 1 month postintervention by blind evaluators.


Type Measure Time Frame Safety Issue
Primary Two primary clinical outcomes characterizing training program effectiveness for improving arm impairment and motor function were FM (Fugl-Meyer Arm Section)and Upper Extremity performance Test (TEMPA). Two primary outcome measures of training program efficacy were trunk displacement and elbow extension ranges.
Secondary Isometric force and manual dexterity (Box and Blocks Test [BBT]), range of shoulder flexion, peak arm tangential velocity, smoothness and hand trajectory straightness.
