Introduction: Plantar Fasciitis (PF) is the most frequent musculoskeletal condition that primarily affects the foot, causing tenderness and disturbed foot function. Need of the study: The planned clinical trial will proceed with the aim of ensuring that the intervention is accessible to the general public, irrespective of the outcomes. This study will help in exploring the effect of HILT, KT and plantar-fascia stretching and to add this method as adjunct to conventional physiotherapy approach in plantar fasciitis sufferers. Aim: To evaluate the effect of combination of {High-Intensity Light Amplification by Stimulated Emission of Radiation (LASER) Therapy HILT)} with Kinesio-taping (KT), and plantar-fascia stretching in improving pain pressure threshold and foot function in individuals suffering from PF. Materials and Methods: A single-blinded randomised clinical trial design will be employed to enroll both male and female participants aged >18 years, with plantar heel pain lasting more than 4 weeks and will be randomly divided into two groups. The experimental group will receive HILT along with KT using the low-dye taping technique, while the comparator group will receive HILT along with plantar-fascia stretching. A power analysis will be conducted to determine the appropriate sample size based on the findings of a pilot study. Outcome measures will include pressure algometry to assess pressure pain threshold and the foot function index to evaluate disability. The study outcomes could either indicate a meaningful difference between the groups or not. This will confirm the practical relevance of the intervention for individuals suffering from plantar fasciitis.
