Cryotherapy and Laser Therapy on Muscle Damage (CLMD)

December 25, 2014 updated by: Jamilson Simões Brasileiro, Universidade Federal do Rio Grande do Norte

Cryotherapy and Laser Therapy do Not Interfere in the Response to Eccentric Exercise-induced Muscle Damage: a Randomized Clinical Trial.

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.

  • Primary Purpose: Treatment
  • Allocation: Randomized
  • Interventional Model: Parallel Assignment
  • Masking: None (Open Label)

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: 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
Other: Cryotherapy
Experimental: 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.
Device: Laser therapy
No Intervention: Control
The control group did not undergo any intervention and remained at rest for 25 minutes.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame

Time Frame: Within the first 3 days
Through the VAS (visual analogue scale).
Within the first 3 days

Secondary Outcome Measures

Outcome Measure
Measure Description
