Background: Carpal Tunnel Syndrome (CTS) is the most common entrapment neuropathy caused by compression of the median nerve within the carpal tunnel. This condition is frequently associated with repetitive and prolonged hand activities, resulting in pain, paresthesia, limited range of motion (ROM), decreased muscle strength, and impaired hand function. Physiotherapy interventions, including ultrasound therapy, stretching, and Upper Limb Tension Test (ULTT) exercise, are commonly applied to reduce symptoms and improve functional performance. Objective: To determine the effectiveness of a combination of ultrasound therapy, stretching exercise, and Upper Limb Tension Test (ULTT) exercise in reducing pain and paresthesia and improving joint range of motion, muscle strength, and hand functional ability in a patient with right-sided Carpal Tunnel Syndrome (CTS). Methods: This study employed a case report design involving a patient with right Carpal Tunnel Syndrome who received four physiotherapy sessions. The interventions consisted of ultrasound therapy, stretching, and ULTT exercise. Clinical outcomes were evaluated using the Visual Analog Scale (VAS), paresthesia assessment, range of motion measurement, Manual Muscle Testing (MMT), and the Boston Carpal Tunnel Syndrome (BCTS) Index. Results: Following four treatment sessions, the patient demonstrated reduced pain and paresthesia, improved range of motion, increased muscle strength, and better functional ability, as reflected by an improvement in the BCTS Index score. Conclusion: The combination of ultrasound therapy, stretching, and ULTT exercise provided favorable clinical outcomes in a patient with right Carpal Tunnel Syndrome. These interventions were associated with reduced pain and paresthesia, enhanced joint mobility, increased muscle strength, and improved functional hand performance after four treatment sessions.
