The purpose of this study was to develop regression equations predicting torque output throughout the range of motion for the human elbow, shoulder, knee, and hip. Twenty-two healthy males participated. Torque values throughout the sagittal plane range of motion (i.e., flexion and extension) of the right elbow, shoulder, knee and hip were recorded (isokinetic dynamometer, 1 rad/sec) and express...

Background: Knee range of motion is an essential outcome measure following total knee arthroplasty and it is important to measure this outcome with a simple and accurate tool. Measurement from digital photographs could provide a superior clinical alternative to the common goniometer as devices for capturing digital photographs are becoming more accessible, measurement accuracy is assisted with ...

BACKGROUND The treatment of knee osteoarthritis with hyaluronic acid or corticosteroid injection has been widely used. The purpose of this study was to compare the efficacy of hyaluronic acid (hylan G-F 20) with triamcinolone acetonide as a single intra-articular injection for knee osteoarthritis. METHODS This study was a prospective, randomized, double-blind clinical trial. Participants with...

Because of demographic changes, ever greater demands are made of knee replacement systems by patients and surgeons. To meet these demands, knee joint systems with increased flexion are currently being marketed. The main hypothesis of the present study was to evaluate the functional outcome of a high flexion TKA in amid-term follow up. 75 consecutive patients (29 men and 46 women) who had primar...

Background: Jumping and landing are common activities in soccer, i.e., associated with Anterior Cruciate Ligament (ACL) injuries in the players, especially when experiencing fatigue. The current study aimed to compare the kinematics of the lower limb joints in jump-landing maneuver among soccer players with and without a history of anterior cruciate ligament reconstruction. Methods: Among acti...

The squat is a well‒known exercise to strengthen the muscles of the lower limb. Conditioning specialists universally agree the squat is among the top three prescribed exercises for sports training, rehabilitation and prehabilitation.1 Previously, there has been much debate about the safety of deep (full range) squats. Strength and conditioning coaches often define a deep squat by amount knee ra...

BACKGROUND The range of motion after a total knee arthroplasty is an important clinical outcome affecting the life of the patient. The aim of this study was to determine the most important factors influencing the postoperative knee flexion in Tehran, Iran. METHODS Between July 2007 and January 2009, on 95 cases of total knee joint replacement (89 patients), who were followed for 1 year postop...

Nonballistic, active range of motion exercises have been advocated as more effective than static stretching for increasing range of motion, yet no published data exist to support this claim. This study compared the effect of nonballistic, repetitive active knee extension movements performed in a neural slump sitting position with static stretching technique on hamstring flexibility. Forty healt...

OBJECTIVES External ankle support has been successfully used to prevent ankle sprains. However, some recent studies have indicated that reducing ankle range of motion can place larger loads on the knee. The aim of this study was to investigate the effect of external ankle support (braces and high-top shoes) on the ankle and knee joint loading during a netball specific landing task. DESIGN A r...
