OBJECTIVE Underlying the ability of the hamstrings to decrease tibial anterior shear is the time of firing in comparison with the quadriceps. This timing may be aided by neural programming during a planned or expected activity. It is theorized that individuals who have better programming ability will suffer fewer anterior cruciate ligament (ACL) injuries due to joint protection through muscular...

Background Patellofemoral pain syndrome (PFPS) is one of the most common causes anterior knee seen in adolescents and adults under age 60 yr. The same quadriceps exercise as forward lunge important treatment PFPS, selective strengthening vastus medialis oblique muscle (VMO) also required. Purpose purpose this study was to compare whether with hip adduction (ADD) neutral position (NEU) affected ...

The photochemical properties of homo- and heterometallic molybdate-based Lindqvist polyoxometalate clusters are investigated in a comparative study and it is shown that vanadium substitution can be used as a facile synthetic tool to optimize the visible light absorption and photocatalytic activity of the cluster. The mono-vanadium substituted unit, [VMo(5)O(19)](3-) shows light absorption up to...

Background. The purpose of this study was to compare outcomes of medial patellofemoral ligament (MPFL) repair or reconstruction. Methods. Fourteen knees that underwent MPFL repair and nine (F5, M4) knees that underwent reconstruction at our institution were evaluated for objective and subjective outcomes. The mean age at operation was 20.1 years for repair and 19.8 years for reconstruction. All...

Patellofemoral joint instability is a complex clinical problem. It may be a consequence of pre-existing anatomical abnormality or trauma. The objectives of this study were to use experimental mechanics to measure patellar stability and to quantify the effects of pathological abnormalities on patellar stability in vitro. Eight fresh-frozen cadaver knees were studied. The patellar stability was m...

AIMS In 40 patients, we attempted to investigate the efficacy of electromyography-biofeedback (EMG-B) on quadriceps muscle strength after arthroscopic meniscectomy. METHODS The patients were randomly divided into two groups each consisting of 20 subjects. For the control group, a classical exercise program was given (five sessions of EMG-B application for 2 weeks postoperatively). Range of mo...

Objectives. To examine and investigate the efficacy of shea nut oil extract (SheaFlex75) in relation to knee osteoarthritis (OA). Methods. Thirty-three patients (age 63.6 ± 5.8 years) with knee OA were recruited. Real-time ultrasound imaging and surface electromyography were used to objectively assess the morphological changes and the activity of vastus medialis oblique (VMO) muscles during a 1...
