The Utilization of a Shoe Insert on Individuals With Unilateral Greater Trochanteric Pain Syndrome on Single Leg Stance, Biomechanics, and Pain Intensity

We hypothesize that the addition of a unilateral neutral shoe insert combined with standard physical therapy (PT+SI) will have greater improvements in pain and function at 12 weeks and 6 months compared to physical therapy with sham inserts (PT+Sham) and physical therapy (PT) alone. In addition, we hypothesize that the addition of a neutral shoe insert in the involved limb will immediately improve biomechanics and pain with the single-leg stance test.

Inclusion Criteria: * Subjects with a history of unilateral hip pain lasting more than three months. * Subjects with a VAS pain score of at least 3/10 localized to the lateral hip. * Subjects with pain with palpation to lateral hip. * Subjects with pain with either resisted hip abduction in relative adduction testing position and/or single leg stance test Exclusion Criteria: * Subjects wearing custom foot orthoses at the time of recruitment. * Subjects who endorse current low back pain ≥ 3 on the NRS or lumbar radiculopathy * Subjects with a medical history of spinal or lower limb surgery in the past 6 months. * Subjects with a medical history of total joint replacement of hip, knee, or ankle on the symptomatic side * Subjects who have had a corticosteroid injection at the hip within the last 12 months; * Subjects demonstrating clinical signs and symptoms of intra-articular hip joint pathology with ≥ 3/10 groin pain including imaging confirmed significant labral tearing requiring surgery or osteoarthritis \> 2 (mild) on Kellgren-Lawrence score on radiographs. * Subjects previously diagnosed with systemic inflammatory conditions; active cancer/malignant tumors; or neurological conditions that would affect gait * Subjects who have had physical therapy within the past 3 months for hip pain * If subjects are unable to commit to 12 weeks of therapy with one supervised session weekly * Subjects who have the intention to perform treatments outside of this study including, but not limited to, dry needling or acupuncture, extracorporeal shockwave, therapeutic ultrasound, a TENEX procedure, medication injection therapies, platelet-rich plasma injections, stem cell injections, and surgery.
