Contralateral Effects of Russian Current on Adolescent Athlete

Effect of Russian Current on Contralateral Muscle Strength in Adolescents Athlete :A Randomized Controlled Trial

The strength loss associated with immobilization causes long term decreases in performance and loss of hours of participation for athletes during rehabilitation period to regain a competitive form. Therefore, reducing such effects throughout the immobilization period is highly preferable. Cross-educational strength transfer to the inactive muscle by means of unilateral strength training may provide an opportunity to avoid strength loss and atrophy.

Study Overview

• Status: Completed
• Conditions: Treatment Side Effects
• Intervention / Treatment: Other: Russian current; Device: elbow support

Detailed Description

After injury and/or surgery, neuromuscular electrical stimulation is widely used to train muscles and enhance muscle strength. and some studies have found it to be superior to voluntary exercise after immobilization . One of the preferred common NMES techniques for muscle strengthening is the Russian current (RC) It stimulates almost all muscle motor units to contract synchronously, resulting in a greater muscle hypertrophy. While some studies exist to confirm the efficacy of this current in the Russian language, there is very little evidence to support its use in English literature. The aim of our study is to investigate the effectiveness of cross education of Russian current on the strength of the contralateral inactive biceps and triceps muscles of the affected elbow in pediatrics athletes to decrease some of the negative effects of immobilization on muscle tissue and enhance recovery.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: Russian current and elbow support group; participants in the experimental group will apply elbow support and will receive Russian current on biceps and triceps muscles of the unaffected elbow three therapy sessions per week for 4 weeks.	Other: Russian current; One of the preferred common neuromuscular electrical stimulation techniques for muscle strengthening is the Russian current (RC) It stimulates almost all muscle motor units to contract synchronously, resulting in a greater muscle hypertrophy.; Device: elbow support; tennis elbow brace is recommended to decrease pain and improve function by restricting the movement of the forearm or relieving loads on the origin of the muscles of the extensor
Active Comparator: elbow support group; Participants in this group will apply elbow support only.	Device: elbow support; tennis elbow brace is recommended to decrease pain and improve function by restricting the movement of the forearm or relieving loads on the origin of the muscles of the extensor
