Combined Bracing, Electrical Stimulation, and Functional Practice for Chronic, Upper-Extremity Spasticity

Abstract

Conventional methods for managing upper-extremity (UE) spasticity are invasive, usually require readministration after a certain time period, and do not necessarily increase UE function. This study examined efficacy of combining two singularly efficacious modalities-UE bracing and electrical stimulation-with functional training to reduce UE spasticity and improve function. Two chronic stroke patients exhibiting UE spasticity were administered the Modified Ashworth Scale (MAS), the upper-extremity section of the Fugl-Meyer Impairment Scale (FM), the Box and Block Test (B&B), and the Arm Motor Ability Test (AMAT). They were then individually fitted for a brace and subsequently participated in treatment sessions occurring 2 days/wk for 5 wk, consisting of (1) 30-min clinical sessions, during which the UE was braced in a functional position while cyclic electrical stimulation was applied to the antagonist extensors of the tricep and forearm, and (2) 15-min, clinically based training sessions, occurring directly after the clinical session. After intervention, participants exhibited 1-point reductions in MAS scores for the affected fingers, FM score increases, and increased ability to perform AMAT activities,. Three months later, both participants retained these changes. Data point to a noninvasive, promising method of managing spasticity and rendering functional changes.
