Effects of duration of hydrocollator pack application on pain and back extensor muscle extensibility in individuals with chronic nonspecific low back pain

Abstract

Objectives: This study aimed to investigate the different durations of superficial heating on pain and back extensor muscle extensibility in individuals with chronic low back pain Materials and methods: Thirty individuals with chronic nonspecific low back pain were randomized into one of 3 intervention groups: no heating, 15-min heating, or 30-min heating in lying position. Pain and back extensor muscle extensibility were measured before and immediately after the intervention session. Results: After 15-minute and 30-minute heating, pain significantly decreased but back extensor muscle extensibility was indifferent among 3 groups. Conclusion: Superficial heating has an immediate effect in pain reduction. While, back extensor muscle extensibility is not different, it is therefore suggested to consider other additional interventions.
