Effect of laughter therapy on chronic head and neck pain.

OBJECTIVE

This study investigated the effects of laughter on chronic head and neck pain.

METHODS

Subjects with chronic head and neck pain of ≥ six months duration occurring at least four days per week participated in this pilot cohort study. Differences in self-reported pain were assessed at baseline, Day 7, Day 14, Day 21 and Day 28 using the Short Form McGill Pain Questionnaire (SF-MPQ), Present Pain Intensity (PPI), and Visual Analog Scale (VAS). Self-reported daily compliance with using the LaughMD™ app for laughter therapy was assessed. A generalized estimating equations approach was used to compare pain scores across study timepoints.

RESULTS

Thirty-five subjects completed the protocol. Pain scores showed a statistically significant reduction over time. Most [71.4% (n=25)] were compliant with app use.

CONCLUSION

Using laughter therapy via an app may be an effective adjunct for managing chronic head and neck pain which are frequent symptoms of orofacial pain.
