Effect of Low Energy Extracorporeal Shockwave on Patients With Bell's Palsy
Condition(s) studied
Investigational drug(s) / intervention(s)
Low energy extracorporeal shockwave therapy: Participants allocated to the experimental group will receive low-energy extracorporeal shockwave therapy (LE-ESWT) using a shockwave device set at a frequency of 10 Hz, energy intensity of 2.5, and a total dose of 2500 shockwaves per session. The treatment will be delivered to two sites along the facial nerve pathway, including the stylomastoid foramen (500 shockwaves) and a point located 1 cm anterior to the ear (2000 shockwaves). Each session will be administered for approximately 15 minutes throughout the intervention period.
Selective physical therapy program: Participants will receive a standardized physical therapy program including neuromuscular reeducation and massage therapy. Facial exercises will be performed in front of a mirror to improve symmetry and facial muscle control, with therapist assistance provided as needed. Massage therapy will be applied to the neck, scalp, and facial regions. Each treatment session will last approximately 30 minutes.
Study summary
This study aims to investigate the effect of low energy extracorporeal shock wave therapy on patients with Bell's palsy.
Eligibility
Primary outcome measure(s)
- CMAP Amplitude Asymmetry Percentage — 6 weeks
Facial nerve function will be assessed using nerve conduction studies (NCS). Compound muscle action potential (CMAP) amplitudes will be recorded bilaterally by stimulating the facial nerve anterior to the mastoid process and recording responses from the nasalis muscle. The percentage of CMAP amplitude asymmetry between the affected and unaffected sides will be calculated as \[(CMAP amplitude affected side - CMAP amplitude unaffected side)/CMAP amplitude unaffected side\] × 100. Lower asymmetry values will indicate improved facial nerve conduction and recovery. Assessments will be performed at baseline and after completion of the treatment program.
