Effect of the Press Tack Needle on Recovery from Muscle Fatigue by Randomized Controlled Trial

sham controlled study

Abstract

[Purpose]The purpose of this paper is to examine whether or not the Press Tack Needle (PTN) treatment enhances the recovery process from muscle fatigue which assists in the therapeutic exercise rehabilitation process. By using the PTN, this paper investigates the recovery effect of the fatigued muscle. Randomized controlled trials were used to compare outcomes.
[Method]Twenty-nine healthy male adults were chosen as subjects. However, crossover study was used to compare the PTN group and the sham group. After two sets of arm curl exercises with isotonic contraction at 10%weight of maximum voluntary contraction, the decrease percentage of exercise repetition was calculated. A PTN or sham was inserted at the posterior cervical region using the double masking method. After the intervention of the PTN or sham needle, the subjects were asked which intervention was inserted into them. A Kappa statistics value was used to evaluate the validity of the sham group and a Visual Analog Scale (VAS) was used to determine the upper arm fatigue.
[Result]The Kappa statistic value was 0.17. The decrease percentage of the exercise repetition of the PTN group was 35.4±20.1%, and of the sham group was 45.1±11.1%. The PTN group indicated a significantly smaller percentage than the sham group (p<0.01). Both groups showed no difference in Upper arm fatigue.
[Conclusion]The PTN seems to help in recovery from muscle fatigue. It is thought that by inserting the PTN, somato-automomic reflex was induced to promote the increase of blood flow in to the muscle. Faster recovery of physical function of the patient can be possible as well as the improvement of QOL. In conclusion, this investigation showed that the PTN treatment method can be useful in assisting in therapeutic exercise rehabilitation.
