Stair Descent in Females With and Without PFPS
This article compliments previous studies investigating hip control and strength in more distal pain syndromes. It develops kinetic chain theory helping clinicians understand the relationship between pain site and pain source. A recurrent theme in the literature shows that hip dysfunction is a consistant patterns in the PFP population. It is contrary to othher stidues who found differences in hip movement pattern in this population.
Hip Strength and Hip and Knee Kinematics During Stair Descent in Females With and Without Patellofemoral Pain Syndrome
Bolgla, Lori et al, 2008
Determine if females with patellofemoral pain syndrome (PFPS) have hip weak and increased hip internal rotation, hip adduction, and knee valgus during stair descent.
18 females with PFPS and 18 matched controls. Strength measures for the hip external rotators and abductors. Hip and knee kinematics were collected as subjects completed a standardized stair-stepping task. Independent t tests were used to determine between-group differences.
Subjects with PFPS generated less hip external rotator and less hip abductor force. No between-group differences for movement.
