Bilateral Training Versus Unilateral Training in Stroke

This study has been completed.

Last updated: August 1, 2014
Last verified: August 2014
This randomized, single-blind study compares the effectiveness of bilateral training to unilateral training for individuals with moderate hemiparesis. We hypothesize that bilateral training will be superior to unilateral in the proximal extremity but not the distal one.

Condition Intervention Phase
Behavioral: bilateral upper extremity training
Behavioral: Unilateral upper extremity training
Phase 2

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Single Blind (Outcomes Assessor)
Primary Purpose: Treatment
Official Title: Bilateral Training for Upper Extremity Hemiparesis in Stroke

Further study details as provided by University of Illinois at Chicago:

Primary Outcome Measures:
  • Motor Assessment Scale [ Time Frame: pre and post (week one and week 8) ]
  • Motor Status Scale [ Time Frame: pre and post, Week 0 and Week eight ]

Secondary Outcome Measures:
  • Reaching Performance Scale [ Time Frame: pre and post training (Week 0 and week 8) ]

Enrollment: 24
Study Start Date: May 2005
Primary Completion Date: August 2007 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: 1
bilateral training
Behavioral: bilateral upper extremity training
Bilateral symmetrical upper extremity training for proximal control for three hours per week for eight weeks.
Active Comparator: 2
Unilateral training
Behavioral: Unilateral upper extremity training
Unilateral upper extremity training for proximal extremity for three hours a week for eight weeks.

Detailed Description:

Upper extremity hemiparesis is the most common post-stroke disability. Longitudinal studies have indicated that 30 to 66 percent of stroke survivors do not have full arm function six months post-stroke. Bilateral arm training has been investigated as a potential rehabilitation intervention for individuals not eligible for constraint induced movement therapy.

This training study included 24 hours of treatment over eight weeks. The protocol consisted of reaching activities with rhythmic auditory cueing emphasizing the proximal arm. Subjects assigned to the bilateral group performed bilateral symmetrical activities while subjects in the unilateral group performed the same activity with the affected arm only. The Motor Assessment Scale-Upper Limb Item and the Motor Status Scale are used as primary outcome measures. The Reaching Performance Scale and strength measures are secondary outcome measures. Assessments are administered pre-/ and post-training by a blind rater.
