Effects of Local Cryo-therapy and Active Exercise on Rheumatoid Arthritis / 日本温泉気候物理医学会雑誌

ABSTRACT

In order to compare the result of local cryo-therapy on rheumatoid arthritis against the conventional local heat application a comparative clinical study was performed.<br>Twenty rheumatoid patients with bilateral knee joint involvement were selected cryo-therapy was given for five minutes with cryogenic air generator (Nihonsanso-L-10) at-100°C on below in eleven patients, whereas local heat was applied with hot packs for 15 minutes at 70-80°C in nine patients.<br>All the patient underwent a daily active exercise schedule after the local treatment, these treatment were given for three months continuously and the result were evaluated. For the evaluation, twelve items were selected including, range of motion, muscle strength, walking capacity, roentgengram and etc.<br>The patients were evaluated before the treatment, 1.5 months after the treatment and at the end of the treatment.<br>The result: both groups showed some improvement in general, but there was no significant difference between them, muscle stiffness and joint pain seemed to be slightly between after the cryo-therapy compared to the local heat application, however post-treatment x-ray showed some progression of joint destruction in the former. The result suggest that local cryo-therapy has a certain place in rheumatoid treatment although not significantly better than the conventional local heat application, if it is applied under due care.
