All 3 modalities were effective in reducing skin temperature and changing sensory conduction at a physiological level that is sufficient to induce a hypoalgesic effect. The results suggest that cold water immersion, as applied in this study, is the most indicated modality for inducing therapeutic effects associated with the reduction of motor nerve conduction.

Joint inflammation stimulated the expression of muscle factors related to atrophy, growth, differentiation, and mass regulation followed by muscle atrophy.

© Revista Brasileira de FisioterapiaEffect of walking and resting after three cryotherapy modalities on the recovery of sensory and motor nerve conduction velocity in healthy subjects Efeito da marcha e do repouso após aplicação de três protocolos de crioterapia na recuperação da velocidade de condução sensorial e motora em sujeitos saudáveis Esperanza Herrera 1 , Maria Cristina Sandoval 1 , Diana M. Camargo 1 , Tania F. Salvini 2 AbstractBackground: Different cryotherapy modalities have distinct effects on sensory and motor nerve conduction parameters. However, it is unclear how these parameters change during the post-cooling period and how the exercise carried out in this period would influence the recovery of nerve conduction velocity (NCV). Objectives: To compare the effects of three cryotherapy modalities on post-cooling NCV and to analyze the effect of walking on the recovery of sensory and motor NCV. Methods: Thirty six healthy young subjects were randomly allocated into three groups: ice massage (n=12), ice pack (n=12) and cold water immersion (n=12). The modalities were applied to the right leg. The subjects of each modality group were again randomized to perform a post-cooling activity: a) 30min rest, b) walking 15 min followed by 15 min rest. The NCV of sural (sensory) and posterior tibial (motor) nerves was evaluated. Initial (pre-cooling) and final (30 min post-cooling) NCV were compared using a paired t-test. The effects of the modalities and the post-cooling activities on NCV were evaluated by an analysis of covariance. The significance level was α=0.05. Results: There was a significant difference between immersion and ice massage on final sensory NCV (p=0.009). Ice pack and ice massage showed similar effects (p>0.05). Walking accelerated the recovery of sensory and motor NCV, regardless of the modality previously applied (p<0.0001). Conclusions: Cold water immersion was the most effective modality for maintaining reduced sensory nerve conduction after cooling. Walking after cooling, with any of the three modalities, enhances the recovery of sensory and motor NCV.Keywords: cryotherapy; cold therapy; nerve conduction; cooling agents; sural nerve; tibial nerve. ResumoContextualização: Diferentes protocolos de crioterapia têm ação distinta nos parâmetros de condução neural sensorial e motora. No entanto, não se sabe como é o comportamento desses parâmetros no período pós-resfriamento e como o exercício físico realizado nesse período atuaria na recuperação da velocidade de condução nervosa (VCN). Objetivos: Comparar o efeito de três protocolos de crioterapia na VCN pós-resfriamento e analisar o efeito da marcha pós-resfriamento na recuperação da VCN sensorial e motora.Métodos: Trinta e seis sujeitos jovens e saudáveis foram alocados aleatoriamente em três grupos: criomassagem (n=12), pacote de gelo (n=12); imersão em água gelada (n=12). As modalidades foram aplicadas na perna direita. Os sujeitos de cada grupo foram novamente aleatorizados para realizar uma atividade pós-resfriamento: a) 30 min de rep...
