Objective To explore the application value of shear wave elastography（SWE）and surface electromyography（s EMG）in the evaluation of therapeutic effect of neck shoulder myofascial pain syndrome（MPS）treated by acupuncturecombined with massage.MethodsNinety patients with neck and shoulder MPS admitted to our hospital were received 4 courses（7 d was 1 course）of acupuncture combined with massage therapy.According to the clinical efficacy of 1 month after treatment

the clinically cured and markedly effective patients were included in group A（54 cases）

effective and ineffective patients wereincluded in group B（36 cases）.Before and after treatment

SWE was used to detect the Young’s modulus

fascia thickness andtissue elasticity score of the two groups

and s EMG was used to detect the average amplitude value and the average frequencyslope value.The above parameters of the two groups were compared.The ROC curve was drawn to analyze the evaluation value ofeach index for the curative effect of patients with neck and shoulder MPS.ResultsBefore treatment

there were no significantdifference of Young’s modulus

fascia thickness

tissue elasticity score

average amplitude value and average frequency slopevalue between the two groups.After treatment

Young’s modulus

fascia thickness and tissue elasticity score of the two groupswere lower than those before treatment（all P<0.05）

while the average amplitude and frequency slope values were higher thanthose before treatment（both P<0.05）. ROC curve showed that the area under the curve of tissue elasticity score

Young’smodulus value

fascia thickness and their combination

average amplitude value

average frequency slope and their combinationwere 0.750

0.812

0.752 and 0.833

respectively.The area under the curve of combined application was0.957

which was higher than alone application（all P<0.01）.ConclusionSWE can objectively reflect the tissue elasticity ofmyofascial trigger points in patients with MPS

while s EMG can reflect muscle activity and fatigue.The combination of the twocan better evaluate the efficacy of MPS

which has important clinical application value.
