Rehabilitation of Soft Tissue Injuries of the Hip and Pelvis.

Clin Sports Med 2021 Apr 10;40(2):409-428. Epub 2021 Feb 10.

Atlanta Braves, Truist Park, 755 Battery Avenue, Southeast, Atlanta, GA 30339, USA.

The athlete's hip is complex when it comes to the surrounding musculature-approximately 21 different muscles can cross the hip and pelvis region, all synchronously working to maintain pelvic stability and functional hip activities. Commonly injured muscle groups for high-level athletes include flexors, adductors, abductors, and/or proximal hamstring musculotendinous complex. These muscle groups work in harmony; however, each has an independent function and propensity for injury. Read More

Hip and Groin Injury Prevention in Elite Athletes and Team Sport - Current Challenges and Opportunities.

Int J Sports Phys Ther 2021 Feb 1;16(1):270-281. Epub 2021 Feb 1.

Oklahoma City Thunder Basketball Club.

Hip and groin injury (HAGI) has been reported as a source of significant time loss in elite sport. Field and court-based sports such as basketball, football, hockey, soccer, among others, require explosive multiplanar movement in single stance and high-speed change of direction. Often situations arise where sub-optimal pre-season training has occurred or congested in-season competition minimizes physiologic recovery periods between bouts of physical activity, both of which could magnify concomitant existing risk factors and increase injury risk.

Hip Displacement in Cerebral Palsy: The Role of Surveillance.

Indian J Orthop 2021 Feb 11;55(1):5-19. Epub 2020 Jun 11.

Paediatric Orthopaedics, Balabhai Nanavati Super Speciality Hospital, Mumbai, India.

Introduction: Hip displacement is common in cerebral palsy (CP) and is related to the severity of neurological and functional impairment. It is a silent, but progressive disease, and can result in significant morbidity and decreased quality of life, if left untreated. The pathophysiology of hip displacement in CP is a combination of hip flexor-adductor muscle spasticity, abductor muscle weakness, and delayed weight-bearing, resulting in proximal femoral deformities and progressive acetabular dysplasia.

Active foot placement control ensures stable gait: Effect of constraints on foot placement and ankle moments.

PLoS One 2020 17;15(12):e0242215. Epub 2020 Dec 17.

Department of Human Movement Sciences, Faculty of Behavioural and Movement Sciences, Vrije Universiteit Amsterdam, Amsterdam Movement Sciences, Amsterdam, The Netherlands.

Step-by-step foot placement control, relative to the center of mass (CoM) kinematic state, is generally considered a dominant mechanism for maintenance of gait stability. By adequate (mediolateral) positioning of the center of pressure with respect to the CoM, the ground reaction force generates a moment that prevents falling. In healthy individuals, foot placement is complemented mainly by ankle moment control ensuring stability. Read More
