O Efeito da crioterapia e compressão interminente no músculo lesado de ratos: uma análise morfométrica

Abstract

Introduction: Although cryotherapy associated with compression has been recommended as an immediate treatment for muscle injuries, the effect of intermittent sessions of these procedures in the area of secondary muscle injuries has not been clearly established. Objective: To evaluate the effect of intermittently applying cryotherapy and compression (three 30-minute sessions at 90-minute intervals) on an injured area of the right tibialis anterior (RTA) muscle in rats. Method: An injury was induced in the RTA muscle by means of cryoinjury. Twenty-four Wistar rats (340 ± 20g) were divided into four experimental groups: a) Injury + Cryotherapy (I+C), which received intermittent cryotherapy and compression; b) Injury + Placebo (I+P), which received placebo treatment; c) Injury (I), which did not undergo any treatment protocols; and d) Cryotherapy, which remained intact and underwent cryotherapy and compression treatment. The animals were sacrificed 24 hours after the injury, and the muscles were sectioned in a cryostat. The histological sections were stained with toluidine blue for subsequent measurement of the area of the muscle injury (morphometry). The statistical analysis consisted of the ANOVA and Tukey tests (p≤ 0.05). Results: The morphometric analysis 24 hours after the injury indicated that there had been a significant reduction in the area of the muscle injury in the I+C group (35.87 ± 4.9%), in comparison with the I+P group (46.4 ± 3.9%; p= 0.001) and the I group (46.5 ± 4.1%; p= 0.002). Conclusion: Three sessions of cryotherapy and compression were efficient in preventing an increase in the injured area, while compression alone did not achieve such effectiveness.

Crioterapia e cinesioterapia no membro superior espástico no acidente vascular cerebral

“…Segundo Soares (19), o uso da crioterapia nos músculos espásticos reduz a hipertonicidade e facilita o manuseio do paciente, tornando possível a realização da cinesioterapia e possibilitando o treino funcional e a prevenção do desenvolvimento de deformidades articulares. Dessa forma, consideramos útil a aplicação da terapia eleita neste estudo, mesmo reconhecendo a limitação dos efeitos observados sobre a redução do padrão postural fl exor da articulação do punho isoladamente.…”

“…De acordo com a literatura, alguns métodos fi sioterapêuticos podem ser aplicados sobre o membro espástico com intuito de reduzir o tônus muscular; um deles é o uso do frio (crioterapia) (11,12,19). A crioterapia é uma termoterapia negativa (13) que foi formulada por neurologistas entre 1945 e 1954, por meio do método Kabat, com objetivo de facilitar a ação neuromuscular (20).…”

Effect of cryotherapy on the ankle temperature in athletes: ice pack and cold water immersion

“…It also causes muscle dysfunctions such as myofibril disturbance, rupture of mitochondria and sarcoplasmic reticulum, interruption of sarcolemma continuity, cellular self-digestion and cell death (2). Additionally, the response to the primary injury can lead to secondary injury, which occurs from both enzymatic and hypoxic mechanisms in the cells on the periphery of the primary injury (3).…”

Acute effects of gastrocnemius muscle stretching after contusion in rats

“…It can be described as mild, moderate and severe, and it presents signs and symptoms such as pain, edema, limited movement range, muscle strength, function and gait, proportionally to the severity of the injury 2 . After an acute muscle lesion, rest has been recommended, as well as cryotherapy/compression/ elevation and early mobilization 2,3 . Frequently, anti-inflammatory medicines are prescribed [4][5][6] , as well as actogevin shots, manipulations and exercises.…”
