  • 4E: Impaired Joint Mobility, Motor Function, Muscle Performance, and Range of Motion Associated with Localized Inflammation1


A 65-year-old physically active and otherwise healthy female (5’7 in, 160 lb) slipped on ice while exiting the passenger side of a car. She described the scenario such that as she attempted to leave the vehicle and stood on her right leg, her foot slipped out beneath her. Although she grabbed onto the door for support and did not fall, she reported feeling a “pulling” sensation and immediate pain over her right inner thigh. She reported to the clinic for assessment—4 days postinjury. She states her inner thigh became “bruised” (black-and-blue) over the past 2 days and the pain has caused difficulty sleeping and performing activities of daily living. As she entered the clinic, she had a slight limp, with shortened stance time noted during right limb ambulation. Her chief complaint is pain. She presented with palpable pain and muscular defect over the mid-muscle belly of her adductor magnus. Active range of motion for hip flexion and extension is within normal limits (WNL), but she reports pain with hip adduction, abduction, and internal/external rotation. Passive ROM elicits pain during hip abduction and external rotation. She has 5/5 strength with hip flexion, extension, external rotation, and abduction; and 4/5 with hip adduction and internal rotation.



  • Partial or complete tearing of the adductor muscles

    • Pectineus

    • Adductor brevis

    • Adductor longus

    • Adductor magnus

    • Gracilis

  • May report feeling a pop/pulling sensation in the muscle

  • Condition may result in abnormal stress to the pubic bone, pubic tubercle, or pubic symphysis

  • Pubalgia–osteitis pubis: A collective term referring to disorders that cause chronic pubic pain

  • Symptoms from increased mechanical stress in pubic region due to abnormalities or stress from osseous, ligamentous, or muscular structures

Essentials of Diagnosis

  • Diagnosed primarily through signs and symptoms, exclusion of other pathologies typical to the region

  • Defect of muscle fibers likely on palpation

  • Grade 1: ...
