Effects of NMES on Muscle Function of Patients With FSHD: a Double-blind Randomized Controled Clinical Trial

Not Applicable

Terminated

• Conditions: Primary Disease Facioscapulohumeral Dystrophy (FSHD)
• Interventions: Device: Current intensity upper of motor threshold by Kneehab XP technology; Other: Current flow between sensory and motor threshold

• Registration Number: NCT02861911
• Lead Sponsor: University Hospital, Montpellier

Brief Summary

Facioscapulohumeral muscular dystrophy (FSHD) is an autosomal dominant disease characterized by progressive weakness and atrophy of specific skeletal muscles. One of the major problems of patients affected by FSHD is the limitation in performing daily activities induced by the progressive muscle weakness. This sedentary lifestyle can cause a "debilitative cycle," and neuromuscular deconditioning can even aggravate the muscular deficiencies. Recent studies have indicated the safety and the effectiveness of moderate aerobic training programs in patients with FSHD. However, these training programs have limited applicability in patients with more severe muscular weakness. Artificial strength training by means of neuromuscular electrical stimulation (NMES) appears to be a promising rehabilitation strategy for FSHD patients suffering from neuromuscular disorders. Therefore we propose to investigate the feasibility, safety, and effectiveness of NMES strength training to counteract quadriceps muscle weakness in patients affected by FSHD.

Detailed Description

NMES will be delivered to both quadriceps by means of a Kneehab® XP device, which is an innovative and clinically-proven garment-based product designed specifically to treat quadriceps muscle atrophy. The main NMES current parameters are: 50-Hz frequency, 100-400 µs pulse duration, 5:10-second on:off time. Each session will last approximately 20 minutes and will be repeated 5 days/week for a total duration of the treatment program of 3 months.

Arm && Interventions

Group	Intervention	Description
Active NMES group	Current intensity upper of motor threshold by Kneehab XP technology	Tthe current intensity must always meet and exceed the motor threshold (patients feel the current and quadriceps muscle will contract a visible and quantifiable if possible).
Control group	Current flow between sensory and motor threshold	The current intensity is generally defined between the sensory and motor threshold (patients feel the power but no visible muscle contraction will be obtained).

Primary Outcome Measures

Name	Time	Method
Maximal voluntary contraction (MVC) strength of the quadriceps	At 3 months

Secondary Outcome Measures

Name	Time	Method
Effect of NEMS on the quality of life (SF36 questionnaire)	At 3 months
Effect of NMES on the quadriceps endurance evaluated in a dynamic test against a charge equal to 30% of maximal isometric force.	At 3 months
Evaluation of the body composition by bioelectric impedance analysis (BIA) after NMES effect	At 3 months
Effect of NMES on the bone mineral density by dual energy X-ray absorptiometry (DEXA)	At 3 months
Effect of NMES on the oxidative stress markers in blood and urine by blood and urine tests	At 3 months
