The knee is the most affected joint in children with cerebral palsy. Flexion contracture of the knee is the cause of the crouch gait pattern, instability in stance phase of gait, and difficulties during standing and sitting, and other daily living activities. Hip flexion contracture in crouch gait is mostly compensation of the knee flexion contracture and ankle equines. The psoas muscle is the ...

[Purpose] The purpose of the present study was to investigate the limb position at which the maximum toe-grip strength could be exerted as well as measurement reproducibility. [Subjects] Twenty healthy young women were selected. [Methods] We measured toe-grip strength under three conditions: 90° hip and knee flexion while sitting, 90° hip flexion and knee extension while sitting, and a standing...

CONTEXT Lateral trunk-flexion strength is an important determinant of overall trunk stability and function, but the reliability in measuring this outcome clinically in athletic individuals is not known. OBJECTIVE To determine the interrater and intrarater reliability of lateral trunk-flexion strength measurement in athletic individuals using handheld dynamometry. DESIGN Reliability study. ...

Background Stiff landings with less knee flexion and high vertical ground-reaction forces have been shown to be associated with an increased risk of anterior cruciate ligament (ACL) injury. The literature on the association between other sagittal plane measures and the risk of ACL injuries with a prospective study design is lacking. Purpose To investigate the relationship between selected sag...

BACKGROUND Stiffness after a TKA can cause patient dissatisfaction and diminished function, therefore it is important to characterize predictors of ROM after TKA. Studies of AP translation in conscious individuals disagree whether AP translation affects maximum knee flexion angle after implantation of a highly congruent sphere and trough geometry PCL-substituting prosthesis in a TKA. QUESTION...

BACKGROUND AND PURPOSE Physical therapists routinely assess spinal active range of motion (AROM) in patients with low back pain (LBP). The purpose of this study was to use 2 approaches to examine the relationship between impairment of lumbar spine flexion AROM and disability. One approach relied on the use of normative data to determine when an impairment in flexion AROM was present. The other ...
