Purpose: to investigate the effect of high intensity laser therapy on pain intensity in patients with acute cervical myofascial trigger points in the upper trapezius muscle. Methods: 50 patients (32 female and 18 male) suffering from myofascial trigger points in the upper trapezius muscle participated in this study. They were all recruited from the out-clinic of the faculty of physical therapy Badr university. Their ages ranged from 20 to 40 years old with body mass index less than 25 kg/m². They were randomly allocated into two equal groups; group A (n=25) received traditional treatment only (transcutaneous electrical nerve stimulation, ultrasound, passive stretch and isometric exercise), group B (n=25) received high intensity laser therapy with traditional treatment. duration of treatment was 2 sessions/week for 4 weeks. Measurement of the visual analogue scale was recorded before and after the intervention. Results: Results showed that there was significant difference between the two groups in the outcome measures in the post treatment assessment, with the intervention administered by group (B) being more significant than the control group (A) at (p >0.001). Conclusion: high intensity laser therapy was found to be significantly effective as a physical therapy modality for patients with cervical myofascial trigger points.
Aim of the study: In athletes, groin pain-related adductor strain is a common problem in sports medicine, like groin injuries, so the study investigated the effect of Photobiomodulation (905 nm) and Trigger Band Technique (TBT) on handball athletes' groin adductor strain. Methods: Forty handball athletes with adductor groin strain were divided into an experimental group (A) that received Diode laser 905nm, TBT, and medical treatment, while control group (B) received sham laser with TBT and medical treatment for four weeks. Outcome measures investigated Copenhangen hip and groin outcome score, pressure algometry, creatine kinase, and lactate dehydrogenase levels. Results: Both groups showed a significant improvement in the post-treatment outcome measures, where experimental group showed more significant improvement than the control group with p-value >0.05. Conclusion: results imply that treatment of handball athlete's groin adductor strain by TBT and low-level laser is more effective than TBT alone.
Aim of the study: As high intensity laser therapy (HILT) is capable of reaching and stimulating deeper and larger tissues than traditional physiotherapy modalities, so we studied its influence on cervical myofascial pain. Subject and methods: 50 patients with chronic upper trapezius muscle myofascial trigger points (MTrPs) within age range of 20 to 40 years old were assigned into group A that received traditional treatment only (transcutaneous electrical nerve stimulation (TENS), ultrasound massage (US), stretch and exercise), while group B received HILT with traditional treatment. Outcome measures included pain severity via visual analogue scale (VAS), pressure pain threshold (PPT) by pressure algometer, neck functional activities by neck disability index (NDI) and cervical range of motion by CROM apparatus. Results: both groups showed significant improvement in the posttreatment outcome measures, but the HILT group (group B) showed a more significant improvement than the control group (group A) with p-value >0.001. Conclusion: HILT is a supportive physical therapy modality that may provide preferable results for a cervical MTrP patient.
