Observation on the intervention effect of massage loosening method combined with PNF stretching method on the imbalance of neck and shoulder muscles of college students

Objective To explore the intervention effect of massage relaxation method combined with PNF stretching method on the imbalance of neck and shoulder muscles of college students, and provide a reference for effectively improving the health of neck and shoulder muscles among college students. Methods Totally 84 college students with neck and shoulder muscle imbalance from March 2017 to March 2018 due to prolonged bowing were selected as subjects. They were randomly divided into two groups (n=42): the control group was given regular strength training, and the observation group was provided with more strength training by Massage relaxation method and PNF stretching method was used for therapeutic intervention. Then the degrees of neck and shoulder muscle pain, joint mobility, round shoulder angle, and head extension angle were compared before and after intervention of two groups. Results Compared with the results before intervention, the VAS score of the observation group was significantly lower after the intervention, and there was no significant change in the control group, and the VAS score of the observation group was (3.23±1.29), which was significantly lower than that of the control group (4.26±1.42) (P<0.05). The head extension angle and the round shoulder angle of the observation group respectively were (28.24±4.14) ° and (35.68±6.29) °, and the control group respectively were (32.21±6.27) ° and (41.86±5.38) °. The difference was statistically significant (P<0.05). The neck joint flexion, extension, left-handedness, right-handedness, left flexion, right flexion, left-handed and right-handed motion of the observation group respectively were (67.24±7.15) °, (68.82±4.66) °, (73.21±4.83) °, (73.56±5.13) °, (38.18±5.14) °and (38.85±2.33) °, all significantly higher than the control group (P<0.05). The muscle tension (left), muscle tension (right), muscle stiffness (left), muscle stiffness (right), muscle elasticity (left), and muscle elasticity (right) of the observation group respectively were (10.21±0.63) Hz, (10.13±0.72) Hz, (174.64±18.15) N/m, (164.34±16.73) N/m, 0.74±0.25 and 0.71±0.33, both significantly lower than the control group (P<0.05). Conclusion Massage loosening combined with PNF stretching method combined with conventional strength training can effectively alleviate the pain caused by the imbalance of neck and shoulder muscles of college students, improve head extension and round shoulder angle, correct neck and shoulder posture, and restore neck and shoulders.
