EFFECTS OF CERVICAL MUSCLES STRENGTHENING WITH AND WITHOUT SHOULDER EXERCISES IN POST-MASTECTOMY PATIENTS WITH NECK PAIN

Background of the Study: To compare the effects of cervical muscles strengthening with and without shoulder exercises on post- mastectomy patients with neck pain. Methodology: It was a randomized clinical trial, conducted in physical therapy department of a clinical setting through Dynamometer. Sample size of 24 patients were taken. Non-probability convenience sampling technique was used. A written consent form was taken from patients meeting inclusion criteria and were randomly allocated. In one group, patients were treated with cervical Muscles strengthening with shoulder exercises. In other group, patients were treated with cervical Muscles strengthening alone. Treatment was given once a day for three weeks. Muscle strength was examined using dynamometer, Baseline data was taken before treatment on first day after inclusion in study and again on the last day after treatment. SPSS 25 was used to analyze the data. Results: Wilcoxon signed rank test was used to compare individuals within the group which showed significant results in both groups, p-value 0.000 (i.e. <0.001) for neck strength. Between groups comparison was done using Mann-Whitney U Test and it showed no significant changes for cervical extensors (p- value;0.143) , cervical side bending (right) (p-value; 0.315) and cervical side bending (left) (p-value; 0.853) strength differences, but however cervical flexors strength showed statistically significant results as p-value was 0.003. Conclusion: It was concluded that Cervical strengthening along with shoulder Rehabilitation can help improve the strength of cervical flexors. However, both the groups have equally resulted in improved cervical extensor, Side bending right and left strength.
