The Effects of Ultrasound with Cool Aquasonic Gel Treatment on Delayed Onset Muscle Soreness of Biceps Brachii Muscle after Eccentric Exercise

Abstract

          This study aimed to compare between the effects of ultrasound with cool gel and ultrasound with normal gel treatment on the delayed onset muscle soreness of biceps brachii muscle after eccentric exercise. The subject consists of thirty-two volunteers, age 18 to 22 years. The subjects were divided four groups (eight subjects per group) composed of the ultrasound with cool gel (USC) group, the ultrasound (USG) group, normal aquasonic gel group (G-sham) and cool aquasonic gel group (C-sham). The subjects perform the eccentric exercise for inducing muscle soreness before treatment. Every groups was evaluated the soreness by visual analog scale, range of motion were measured by goniometer and arm circumference were measured by tape measurement before eccentric exercise and after eccentric exercise at  24, 48 and 72 hours. he results of this study found that the pain scale of ultrasound with cool gel group was statistically decreased at 48 and 72 hours (p<0.05). Moreover, the range of motion of the ultrasound with cool gel group was statistically increased at 48 and 72 hours (p<0.05) when compared with ultrasound with normal gel group. In addition, the muscle swelling of the ultrasound with cool gel group was statistically decreased at 72 hours but did not different when compared with the ultrasound with normal gel group

          This study concluded that the treatment by using ultrasound with cool gel can reduced the symptoms of delayed onset muscle soreness (DOMS), decreasing pain and improved range of motion better than conventional ultrasound treatment.
