“…16 It is also possible that the lower stiffness observed in the AGP group was simply due to reduced neuromuscular capacity, particularly at the ankle and knee. Training volume and intensity is often limited in subjects with AGP, to manage the pain, 35 and neuromuscular detraining can occur in as little as 4 weeks. 36 Finally, it is possible that the lower stiffness in the AGP group may reflect a neuromuscular risk factor for AGP with increased joint laxity and strain on localized tissues.…”

Athletic groin pain (AGP) is a common injury prevalent in field sports. One biomechanical measure that may be of importance for injury risk is stiffness. To date however, stiffness has not been examined in AGP. The primary aim was to determine whether AGP affects vertical and joint stiffness and if so, whether successful rehabilitation is associated with a change in stiffness. Sixty-five male patients with AGP and fifty male controls were recruited to this study. Assessment included a biomechanical examination of stiffness during a lateral hurdle hop test. Subjects with AGP were tested pre- and post-rehabilitation, while controls were tested once. AGP subjects were cleared for return to play in a median time of 9.14 weeks (5.14-29.0). Stiffness was significantly different at pre-rehabilitation in comparison with controls for four of the ten stiffness values examined: ankle plantar flexor, knee extensor, hip abductor, and vertical stiffness (P < .05, D = 0.36-0.79). Despite clearance for return to play, of these four variables, only hip abductor stiffness changed significantly from pre- to post-rehabilitation (P = .05, D = 0.35) to become non-significantly different to the uninjured group (P = .18, D = 0.26). These findings suggest that hip abductor stiffness may represent a target for AGP rehabilitation. Conversely, given the clearance for return to play, the lower sagittal plane and vertical stiffness in the AGP group in comparison with the uninjured controls likely represents either a compensatory mechanism to reduce the risk of further injury or a consequence of neuromuscular detraining.

“…The iliopsoas musculotendinous unit is located directly anterior to the hip joint and is composed of the iliacus, psoas major, and psoas minor . The most common cause of groin injury arises from the adductor, followed by the iliopsoas . The iliopsoas has been recently implicated in 25% of acute groin injuries .…”

“…In artistic sports, a repetitive and extreme range of hip flexion is frequently performed, and pain associated with a snapping iliopsoas tendon was found in 58% of dancers . Left untreated, iliopsoas injuries such as iliopsoas tendinopathy can become chronic and greatly impair sport performance . Management of iliopsoas tendinopathy consists of rest, activity modification, nonsteroidal anti‐inflammatory drugs, physical therapy, and corticosteroid injections .…”

Objectives Treatment for iliopsoas tendinopathy includes ultrasound (US)‐guided iliopsoas peritendinous corticosteroid injection. Evidence is lacking regarding US‐guided iliopsoas injection efficacy in patients with iliopsoas tendinopathy and intra‐articular (IA) hip abnormalities. The purpose of this study was to examine the efficacy of US‐guided iliopsoas corticosteroid injection for iliopsoas tendinopathy in patients with and without IA hip abnormalities. Methods This work was a prospective study evaluating patients aged 12 to 50 years with iliopsoas tendinopathy. Participants completed a Hip Disability and Osteoarthritis Outcome Score (HOOS) questionnaire before and 6 weeks after injection. The main outcome measure was the change in HOOS subcategory scores. Independent variables included time and hip status. Normal hips were compared to abnormal hips with IA abnormalities. A 2‐way repeated measures analysis of covariance with effect size (η2) was used to determine injection effects on HOOS scores before and 6 weeks after injection. Results A total of 178 patients (154 female and 24 male) were analyzed. Time effects were found for both normal and abnormal hips in all HOOS subcategories: symptoms (P = .041; η2 = 0.050), pain (P = .001; η2 = 0.184), activities of daily living (P = .011; η2 = 0.076), function in sports and recreation (P = .001; η2 = 0.151), and quality of life (QOL; P = .001; η2 = 0.193). Significant differences between normal versus abnormal hips were found in the sports and recreation (P = .032; η2 = 0.056) and QOL scores (P = .001; η2 = 0.135). Conclusions In patients with iliopsoas tendinopathy, US‐guided iliopsoas corticosteroid injection improved outcomes regardless of coexisting IA hip abnormalities. Patients without IA hip abnormalities showed greater improvement in sports and recreation and QOL scores compared to patients with IA hip abnormalities. Ultrasound‐guided iliopsoas injection for iliopsoas tendinopathy may advance short‐term care and help continue with nonsurgical treatment regimens.
