The Role Of Cold Therapy

Among them, touch and cold receptors are the most obvious; muscle contraction ability decreases after being cold, which is related to the decrease of muscle spindle excitability, slower nerve conduction speed, and increase of tissue viscosity Related; due to increased tissue viscosity, weakened muscle strength, joint stiffness, reduced range of motion; reduced local tissue metabolism; changes in cell permeability, local exudation and thus reduced.

The above-mentioned local reactions are all reversible, and the strength of the reaction depends on the speed and amplitude of the temperature drop, the duration and the scope of the cold. The systemic reaction caused by local cold therapy is related to the strength of the local reaction.

When the area is small, the time is short, and the cooling rate is not large, the systemic reaction is small or cannot cause the systemic reaction; on the contrary, it causes chills, reduced sweating, and slower heart rate. Phenomenon such as deep breathing.
