Physiotherapy Management of Left Iliopsoas Muscle Strain in A State-Level Sprinter: A Case Report

Background: The iliopsoas muscle is the primary hip flexor and plays a crucial role in sprinting. Athletes are more prone to muscle strain when they expose the hip flexor group to excessive loading, poor movement mechanics, or sudden high-intensity activities such as Olympic lifting, rapid acceleration, and deceleration activity. Iliopsoas muscle strain commonly presents with groin pain, reduced range of motion, and impaired athletic performance. The goals of the patient and the physical therapist are the same: to create a pain-free environment for the patient and allow him to return to their previous activity level pain-free. Methods: A single case study was conducted on a 20-year-old male state-level sprinter diagnosed with left iliopsoas strain (Grade I). Baseline assessment included pain (NPRS), range of motion, palpation findings, and functional limitations. Physiotherapy interventions included RICE protocol, ultrasound therapy, trigger point release therapy, progressive strengthening, and sport-specific rehabilitation over 1–2 weeks. Data Analysis: Descriptive analysis was used to compare pre- and post-intervention outcomes, including pain intensity, movement, functional ability, and performance. Results: Pain reduced from NPRS 6/10 to 1/10, hip range of motion improved, and the athlete regained functional abilities, including running acceleration and ADLs, without discomfort. Conclusion: Physiotherapy plays a pivotal role in the management of hip flexor strains by reducing pain, restoring mobility, improving neuromuscular control, and progressively reintroducing functional and sport-specific activities. Early intervention and progressive rehabilitation are essential for optimal recovery in athletes.
