[Purpose] The study investigated the effects of lower extremity injuries on aerobic exercise capacity, anaerobic power, and knee isokinetic muscular function in high school soccer players. [Subjects and Methods] The study assessed U High School soccer players (n=40) in S area, South Korea, divided into 2 groups: a lower extremity injury group (n=16) comprising those with knee and ankle injuries...

OBJECTIVE To explore physical and psychological measures believed to determine patients' perceived self-efficacy in the rehabilitation of patients with anterior cruciate ligament injury. DESIGN An explorative descriptive study. PATIENTS A total of 116 patients with an anterior cruciate ligament deficient or reconstructed knee. METHOD At one visit; 12 months post-injury/reconstruction, pat...

BACKGROUND The important purpose of a powered gait orthosis is to provide active joint movement for patients with spinal cord injury. OBJECTIVES The aim of this study was to clarify the effect of a powered gait orthosis on the kinematics and temporal-spatial parameters in paraplegics with spinal cord injury. STUDY DESIGN Quasi-experimental. METHODS Four spinal cord injury individuals expe...

background :rupture of the anterior cruciate ligment (acl) is a common knee injury. the purpose of this study was to determine the balance control in football players with and without acl reconstruction in posture of injury.   methods : sway of the center of gravity of 15 patients with acl reconstruction was compared with 15 healthy, age and sex-matched subjects as the control group. all tests ...

Anterior cruciate ligament (ACL) injury is a common sports injury, particularly in females. Gender differences in knee kinematics have been observed for specific movements, but there is limited information on how these findings relate to other joints and other movements. Here we present an integrated analysis of hip, knee and ankle kinematics across three movements linked to non-contact ACL inj...

QUESTION Is four weeks of home-based balance training more effective than four weeks of home-based strength training at decreasing pain in patients with knee osteoarthritis? DESIGN Randomised trial with concealed allocation and assessor blinding. PARTICIPANTS 48 community volunteers with knee osteoarthritis. INTERVENTION Two groups undertook home-based exercise programs: one group perform...

The prediction and prevention of knee joint injury is an important aspect of preventive health science. This paper proposes a new coupled–loading–rate hypothesis, which states that the main cause of knee injury is a Euclidean jolt, or SE(3)−jolt, an impulsive loading that strikes knee in several coupled degrees-of-freedom simultaneously. Informally, it is a rate-of-change of acceleration in 6-d...

Background: Anterior cruciate ligament (ACL) reconstruction is frequently performed to restore knee stability and function following ACL injury. Female sex is known to predispose to ACL injury; however, it remains unclear whether female sex predisposes to poor outcomes following ACL reconstruction. We hypothesized that male and female patients exhibit no differences in (1) graft failure risk, (...

The purpose of this study was to describe the incidence, severity, mechanism, and intrinsic risk factors for knee injuries in Japanese collegiate rugby union players. Initially, 119 rugby union players from one university club were registered in this prospective cohort study. The occurrence of knee injuries was recorded by a team doctor and athletic trainers during the 2009-2012 playing seasons...

BACKGROUND Severe traumatic knee injury, including injury to the anterior cruciate ligament (ACL), leads to impaired sensorimotor function. Although improvements are achieved by training, impairment often persists. Because good sensorimotor function is associated with better patient-reported function and a potential lower risk of future joint problems, more effective treatment is warranted. Tem...
