The aim of this study was to assess the feasibility of applying a
novel neuromuscular electrical stimulation system, targeting shoulder flexion,
elbow extension, wrist extension, and individual finger extensions, to improve
motor control and function of the hemiparetic upper limbs in chronic stroke
patients. DESIGN: Fifteen participants with chronic (>1 yr after cerebrovascular
accident) upper limb hemiparesis were enrolled. The subjects underwent upper limb
training for 60 mins per day, 6 days per week, for 2 wks, using both a
shoulder-and-elbow stimulation device and a wrist-and-finger stimulation device
developed by the study investigators. Outcomes were assessed using the upper
extremity component of the Fugl-Meyer assessment, the action research arm test,
and the modified Ashworth scale before and after intervention. RESULTS: All
patients completed the training successfully using the neuromuscular electrical
stimulation system without any safety incidents or other complications reported.
Nonparametric statistical analyses indicated significant improvements in the
upper extremity component of the Fugl-Meyer assessment and action research arm
test scores, both at P < 0.01. There were also significant reductions in modified
Ashworth scale scores for the elbow and the wrist flexor, both at P < 0.01.
CONCLUSIONS: The multimuscle stimulation approach and method presented in this
study seem feasible, and the improvements of upper limb motor control and
functional test in chronic stroke patients justify further controlled
investigation.
