High Intensity Laser VS High Power Pain Threshold Ultrasound in Treatment of Plantar Fasciitis

The purpose of the study is to 1. Investigate the Effect of High-intensity laser therapy versus High power pain threshold ultrasound on pain level in patients with plantar fasciitis. 2. Investigate the Effect of High intensity laser therapy versus High power pain threshold ultrasound on ROM in patients with plantar fasciitis.

Plantar fasciitis (PF) is one of the most prevalent musculoskeletal disorders of the foot, affecting individuals across different age groups and activity levels. It is clinically characterized by localized pain at the medial aspect of the heel, typically exacerbated during weight-bearing activities, with marked intensity upon the first steps in the morning or following periods of prolonged rest or non-weight bearing. Persistent symptoms may significantly impair functional mobility and quality of life. Among contemporary conservative management strategies, laser therapy has emerged as a promising non-invasive modality for PF treatment. Recently, High-Intensity Laser Therapy (HILT) has been introduced as an advanced therapeutic option. Due to its high peak power and deeper tissue penetration capability, HILT can effectively stimulate large and deep fascial structures, potentially enhancing tissue repair, modulating inflammation, and reducing pain perception. High-Power Pain Threshold Ultrasound (HPPTUS) represents a modified therapeutic ultrasound technique that delivers energy at intensities approaching the patient's pain threshold. This approach aims to maximize deep tissue stimulation while maintaining patient tolerance. HPPTUS has demonstrated superior clinical outcomes compared to conventional ultrasound techniques, particularly in the management of myofascial pain syndrome, with significant reductions in pain intensity and improvements in range of motion (ROM) achieved within fewer treatment sessions. The study aims to Investigate the Effect of High intensity laser therapy versus High power pain threshold ultrasound in the treatment of plantar fasciitis.
