Objective To observe the influence of manipulation of regulating Jingjin-（soft tissue）and adjusting cervical joints on the fatigue severity of cervical muscles in cervical spondylosis patients.Methods Sixty patients with cervical spondylosis were randomized into treatment group and control group with 30 in each.The treatment group was treated with manipulation of regulating Jingjin and adjusting cervical joints

once every other day

three times a week

for 2 weeks.The control group was treated with traction

once everyday

five times a week

for 2 weeks.Before and after treatment

both groups were tested with TeleMyo 2400T Surface EMG to measure the fatigue severity of cervical muscles

including integrated EMG（IEMG）

and mean power frequency（MPF）and middle frequency（MF）.Results After treatment

the IEMG

MPF

and MF of the right side cervical muscles of both groups and the left side cervical muscles of the treatment group were significantly improved（P< 0.05）.The IEMG

MPF

and MF of the right side cervical muscles and the IEMG of the left side cervical muscles of the treatment group were more significantly improved than those of the control group（P<0.05）.Conclusion Manipulation of regulating Jingjin and adjusting cervical joints can increase the recruitment amount of motor neurons and discharge frequency of motor unit of cervical muscles in cervical spondylosis

thus relieving the fatigue severity of cervical muscles.
