Cryotherapy and Laser Therapy on Muscle Damage

Phase 4

Completed

• Conditions: Myalgia [C05.651.542]
• Interventions: Other: Cryotherapy; Device: Laser therapy

• Registration Number: NCT02327988
• Lead Sponsor: Universidade Federal do Rio Grande do Norte

Brief Summary

This study propose investigate the effect of cryotherapy and laser therapy in response to strenuous exercise-induced muscle damage on the biceps brachii muscle (muscle of the arms). All the individuals underwent to an strenuous exercise protocol (2 series of 10 contractions of non-dominant elbow flexors) and three assessments (pre, post and 48hr after the exercise), composed of pain sensation, measure of the strength and muscle activation.

Arm && Interventions

Group	Intervention	Description
Cryotherapy	Cryotherapy	To the cryotherapy group a 1kg ice pack was strapped over the entire brachial biceps muscle and adjacent muscles of the arm under study using a bandage, and the application lasted 25 minute laser
Laser therapy	Laser therapy	The laser therapy group received laser application to the muscle belly of the non-dominant upper limb brachial biceps at four different points.

Primary Outcome Measures

Name	Time	Method
Pain sensation	Within the first 3 days	Through the VAS (visual analogue scale).

Secondary Outcome Measures

Name	Time	Method
Strength	Within the first 3 days	The strength will be measure through isokinetic dynamometry and the variables analyzed will be peak torque normalized for body weight and power.
Muscle activation	Within the first 3 days	Measured by surface electromyography.
