Address:    Dr.    Peeyoosha    Gurudut,    PT.,    Department    of    Orthopedic    Physiotherapy,    KLEU    Institute    of    Physiotherapy,    JNMC    Campus, Nehrunagar, Belagavi, Karnataka, India 590010 E-Mail:   peeoo123@yahoo.com ABSTRACT Background:   Positive   effect   of   Low   Level   LASER   Therapy   (LLLT)   and   Ultrasound   therapy   (UST)   have   been   studied   before   for   Trigger   Point. however combination of both LLLT and UST therapy have not been studied. Objective:   To   compare   the   effect   of   LLLT,   UST   Alone   each   and   combined   therapy   of   both   along   with   trigger   point   release   on   Trigger   points through pressure pain threshold (PPT), Grades of tenderness. Methods:      45   participants   with   at   least   one   Myofascial   Trigger   Point   were   recruited   and   systematically   assigned   to   one   of   three   groups: UST   (6   sessions),   LLLT   (3   sessions),   both   UST   (6sessions)   and   LLLT   (3sessions)   along   with   trigger   point   release   for   all   the   groups.   Outcome measures were assessed after one week treatment: pressure pain threshold (PPT) and Grades of Tenderness of trigger point. Results :   Pre   and   Post   treatment   values   showed   statistically   significant   results   for   all   the   groups.   When   comparisons   were   made   within   the groups, combined UST and LLLT showed significant results over US and LLLT alone. Conclusion :   The   study   demonstrated   that   combination   of   UST   and   LLLT   is   found   to   be   effective.   Thus   administration   of   both   modality   as combined therapy for trigger point can be used for clinical purpose.
