Values are presented mean ± standard deviation (%). The rate of change in each movement for the resting state. MT, middle trapezius; RH, rhomboid major; HAB, shoulder horizontal abduction; Ext, shoulder extension; ExRot, shoulder external rotation; ExY, extension with Y. aThere is a significant difference from HAB%. bThere is a significant difference from Ext%. *p < 0.05, **p < 0.01.
