EXPLORING EFFECTIVENESS OF LOW LEVEL LASER THERAPY IN THE TREATMENT OF PATIENTS WITH BELLS PALSY

The aim of the proposed research is to explore effectiveness of Low Level LASER Therapy in the country and to compare its effectiveness with routine physiotherapy. The societal benefit of submitted research is to formulate a guideline for physical therapy clinicians of the country to treat patients with Bell's Palsy through modern tool of Low Level LASER Therapy if found effective for improvement in quality of lives

Annually, incidence of Bell's Palsy ranges between 1 to 4 per 10,000 individuals globally. From Pakistan figures highlight that the incidence rate of Bell's palsy in Pakistan may be above the international average, with many patients reporting a decline in their quality-of-life post diagnosis.

Low-Level Laser Therapy (LLLT), a modality known as photobiomodulation, has woven its way through various medical settings over the past decades. It has found applications in promoting wound healing, alleviating musculoskeletal pain, and now is being explored in the realm of neurological recovery. This non-invasive therapeutic technique employs non-thermal lasers or LEDs, aiming to stimulate and enhance the functions of our cellular machinery.

Globally Studies have proved effectiveness of Low Level LASER therapy in Bell's Palsy, with reduction of recovery time, improvement of Quality of Life and Personal wellbeing of patients of Bell's Palsy. We performed a survey exploring treatment preferences of Physical Therapy Clinicians to treat patients with Bell's Palsy; result showed routine contemporary practices of physiotherapy with Low Level LASER Therapy were low as 8% professionals.

The target population in this study will be assessed with standard outcome measures including FDI, HBS, FNLT / NCS and SBFGS. Two outcome measures FDI and HBS has been translated in Urdu and Reliability Studies have also been completed with permission from the Authors. A Case Control study has also been completed considering the risk factors for patients with Bell's Palsy. A Systematic Review completed by the researcher also found the Gap to explore the effectiveness of Low Level LASER Therapy for patients with Bell's Palsy.

The aim of the proposed research is to explore effectiveness of Low Level LASER Therapy in the country and to compare its effectiveness with routine physiotherapy. The societal benefit of submitted research is to formulate a guideline for physical therapy clinicians of the country to treat patients with Bell's Palsy through modern tool of Low Level LASER Therapy if found effective for improvement in quality of lives.
