Brief Summary

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.

Outcome Measures

Primary Outcomes (1)

  • muscle strength

    The concentric isokinetic elbow flexors and extensors peak torque in Newton-meters, for the dominant side (affected side) will be recorded.

    4 weeks

Study Arms (2)

Russian current and elbow support group

EXPERIMENTAL

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 currentDevice: elbow support

elbow support group

ACTIVE COMPARATOR

Participants in this group will apply elbow support only.

Device: elbow support

Interventions

Russian currentOTHER

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.

elbow supportDEVICE

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
