Electrical Stimulation in Denervated Muscles of the Upper Limbs - Effect on Muscle Morphological Properties - a Pilot Study
In Brief
A clinical study evaluating Stimulation of denervated muscles for Tetraplegia. Completed, enrolled 20 participants across 1 site.
Detailed Summary
In the last decade the stimulation of denervated muscles got more attention. Not at least because of the promising results of the RISE project (Use of electrical stimulation to restore standing in paraplegics with long-term denervated degenerated muscles). In this European project it was shown that electrical stimulation of denervated muscles in spinal cord injuries (SCI) increased muscle mass and improved the trophic situation of the lower extremities. Furthermore, structural altered muscle into fat- and connective tissue could be restored into contractile muscle tissue by stimulation. However, only a few studies investigated the effect of direct muscle stimulation in case of peripheral nerve damage in the upper extremities. None investigated the stimulation effect in denervated or partially denervated muscles in the upper extremities in tetraplegic patients.
Study Details
Timeline
Interventions
The study investigates the effect of electrical stimulation on denervated muscles in the forearm and hand regarding muscle structure and thickness. The study will be performed on tetraplegics who have either paralysed the wrist extensor, the short thumb spreader or the muscle between the thumb and index finger.The study lasts 12 weeks and consists of an ultrasound examination at the beginning and end of the study and an intermediate stimulation phase.The stimulation takes place either during an inpatient stay or at home for 12 weeks, 5 times a week 33 minutes.
