Objective:
Evaluate the effectiveness of electrical stimulation and biofeedback on the recovery of tenodesis grasp in tetraplegic individuals during the initial phase of acute rehabilitation.
Design:
A 2 x 2 block design was used with subjects randomized to treatment groups. Forty-five subjects completed the study.
Setting:
Inpatient occupational therapy department.
Subjects:
Inpatients with tetraplegia, first admission for rehabilitation after an acute spinal cord injury.
Interventions:
The four treatment groups were: conventional treatment, electrical stimulation, biofeedback, and combined electrical stimulation and biofeedback. The treatment period was between 5 and 6 weeks.
Main Outcome Measures:
Manual muscle testing and scoring of activities of daily living performance by a blinded evaluator.
Results:
All four treatment groups showed improvements. No treatment group was superior to the others.
Conclusions:
Biofeedback and electrical stimulation alone or in combination offer no advantages over conventional rehabilitation treatment of wrist extensors in tetraplegic patients after spinal cord injury.
