Effect of using an 8-figure shoulder brace on arm swing angle and gait parameters in chronic stroke patients: a pilot randomized controlled study

ABSTRACT

Background

The 8-figure shoulder brace during treadmill training (8-FSBTT) intervention can stabilize the shoulder joint, improve the upright of the thoracic spine, induces a change in the angle of the arm during walking, and consequently improve walking ability in stroke patients.

Objectives

Our objective is to compare the effects of a 4-week program of 8-FSBTT with those of only treadmill training (OT) on arm swing angle, and gait parameters (gait speed, cadence, and both side stride lengths) in chronic stroke patients.

Methods

Participants were randomized to either the 8-FSBTT (n = 11) or OT (n = 11) group. Patients in both groups underwent standard physiotherapy for 30 min per session. In addition, 8-FSBTT and OT interventions were performed 10 min, 5 times per week for 4 weeks. Arm swing angle, gait speed, cadence, and both side stride lengths were measured after 4 weeks of training.

Results

After 4 weeks of training, the 8-FSBTT group showed significant improvement in all outcome measures compared with baseline (p < 0.05). Furthermore, Arm swing angle, gait speed, cadence, and both side stride lengths showed greater improvement in the 8-FSBTT group compared to the OT group (p < 0.05).

Conclusions

This study demonstrated that 8-FSBTT training, combined with standard physiotherapy, improved Arm swing angle, gait speed, cadence, and both side stride lengths in the chronic stroke patients.
