Brief Summary

Cryotherapy is a resource applied thermal rehabilitation in order to reduce skin temperature and muscle as well as nerve conduction velocity, and promotes vasoconstriction of arteries and veins resulting in decreased blood flow.

Conditions

Healthy Individuals

Outcome Measures

Primary Outcomes (1)

• Evaluate the strength and muscle synergism after cryotherapy immersion

  The objective of this study is to Evaluate the strength and muscle synergism between wrist flexors and extensors after forearm immersion cryotherapy. Testing grip strength will be carried out 3 times in a row, with 4 seconds of maximum voluntary isometric contraction, with a 1 minute interval between them; before, immediately after, 25 minutes and 50 minutes after immersion. Strength evaluation is conducted using a load cell. Concurrent with this test, the signal will be collected electromyographic extensor and flexor wrist, upper and middle trapezius fibers and anterior serratus.
