ObjectiveThe current study aimed to determine the effectiveness of post-isometric relaxation and LASER treatment in minimizing pain and increasing neck range of motion and function in people with upper Trapezius trigger point pain.MethodsA total of 45 participants with upper Trapezius trigger point pain were studied. All the participants were randomly assigned into three equal groups (post-isometric relaxation, LASER, and Control) to receive the respective treatments for 1 week. The pressure threshold meter was used to assess the pain-pressure sensitivity of myofascial trigger point pain. Pain intensity and cervical range of motion were measured using the visual analogue scale and cervical goniometry, respectively. The neck disability index was used to assess neck function.ResultsThe results of within group analysis indicate significant changes in all the outcomes in three groups (All groups, P = 0.001) except an insignificant improvement of pain pressure threshold in the control group (P = 0.069). Additionally, there were significant differences noted among three groups on pain-pressure threshold and visual analogue scale scores at posttest day 1, day 5, and day 12 (all P = 0.001). However, there was non-significant improvements of neck disability index and side flexion on both sides noted at all timelines except (all P > 0.05), a significant improvement at posttest day 5 (P = 0.015) among three groups.ConclusionsBoth PIR and LASER treatment have been effective in reducing pain-pressure threshold and pain intensity in the management of muscle trigger point pain. Long-term studies are warranted to further validate the effectiveness of these modalities in the management of upper Trapezius trigger point pain.
