Effect of 's subcutaneous needling on thickness and elasticity of affected muscles in shoulder neck pain based on ultrasonic elastography / 中国针灸

ABSTRACT

OBJECTIVE@#To observe the effect of 's subcutaneous needling on thickness and elasticity of affected muscles in subjects with shoulder neck pain by ultrasonic elastography.@*METHODS@#A total of 30 subjects with upper trapezius pain and local tenderness, or stiffness and funicular nodules were observed randomly, right shoulders were as observation group and left shoulders were as control group. Simple resistance training was adopted in the control group. At the same time of the resistance training, sweeping technique of 's subcutaneous needling was adopted at the local tenderness or the stiffness and funicular nodules of upper trapezius in the observation group. The treatment was given once in both groups. Before and immediately after treatment, thickness and elasticity of bilateral upper trapezius and supraspinatus were observed by ultrasonic elastography, and the variations of visual analogue scale (VAS) score were observed in the two groups.@*RESULTS@#Compared before treatment, the elasticity of upper trapezius and supraspinatus were decreased after treatment in both groups (<0.05), and those in the observation group were lower than the control group (<0.05). Compared before treatment, the VAS scores after treatment were decreased in both groups (<0.05), and that in the observation group was lower than the control group (<0.05).@*CONCLUSION@#'s subcutaneous needling can increase the elasticity and release the muscular tension of affected muscles, and relieve pain in subjects with shoulder neck pain.
