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.engMahidol UniversityHot packDurationBack painOriginal ArticleFaculty of Associated Medical Sciences Khon Kaen University
