Effects of static stretching as compared to autogenic inhibition and reciprocal inhibition muscle energy techniques in the management of mechanical neck pain: a randomized controlled trial.

OBJECTIVE

To compare the effects of static stretching with autogenic inhibition and reciprocal inhibition muscle energy techniques on pain, disability and range of motion in patients with mechanical neck pain.

METHODS

A parallel design randomised controlled trial was conducted at Fauji Foundation Hospital and Railway-General Hospital, Rawalpindi, Pakistan, from April to November, 2017, and comprised of patients aged 18-70 years with neck pain of moderate intensity scoring 4-8 on numeric pain rating scale with limited or painful range of motion. The patients were randomly allocated via lottery method into static stretching group, autogenic inhibition muscle energy technique group and reciprocal inhibition muscle energy technique group. All the subjects received five consecutive treatments sessions. Outcome measurements included numeric pain rating scale score, neck disability index score and goniometry for cervical range of motion. Data was collected at baseline and after first and fifth sessions, and was analysed using SPSS 21.

RESULTS

Of the 78 subjects, there were 26(33.3%) in each of the three groups. Of them 7 were lost to follow-up and the study was completed by 71(91%) subjects. The overall mean age was 41.55±11.89 years (p>0.05). There was no significant difference between the groups at baseline (p>0.05). However, at first and second follow-up, there was a significant difference (p<0.05) between the groups in terms of immediate and short-term relief, except for immediate effects related to range of motion (p=0.056).

CONCLUSIONS

Significant difference existed among static stretching, autogenic inhibition and reciprocal inhibition groups in terms of pain, disability and range of motion in patients with mechanical neck pain.
