Comparative Study
Muscle activation of vastus medialis obliquus and vastus lateralis during a dynamic leg press exercise with and without isometric hip adduction.
To investigate the effects of submaximal and vigorous isometric hip adduction on the vastus medialis obliquus (VMO) and vastus lateralis (VL) activity during the leg press exercise from 90° of knee flexion until full extension. ⋯ Targeted training using the leg press exercise to the last 45° of knee extension/flexion with vigorous hip adduction may be useful in promoting a greater VMO/VL ratio.

Kinesio Taping (KT) is a therapeutic method used by physical therapists and athletic trainers in combination with other treatment techniques for various musculoskeletal and neuromuscular problems. However, no research has evaluated the effect of KT in patients with low back pain (LBP). The purpose of this case was to describe the application of posterior pelvic tilt taping (PPTT) with Kinesio tape as a treatment for chronic LBP and to reduce the anterior pelvic tilt angle. ⋯ The case study demonstrated that PPTT intervention favourably affected the pelvic inclination and sacral horizontal angle, leading to beneficial effects on sacroiliac joint dysfunction (SIJD) and medial buttock pain. Additional research on the clinical effects of this taping procedure requires greater numbers of athletes with SIJD or LBP who have inappropriate anterior pelvic tilt angles and hyperlordosis.

Comparative Study
EMG of the hip adductor muscles in six clinical examination tests.
To assess activation of muscles of hip adduction using EMG and force analysis during standard clinical tests, and compare athletes with and without a prior history of groin pain. ⋯ Hip adduction strength assessment is best measured at hips 0 (which produced most force) or 45° flexion (which generally gave the highest EMG output). Muscle EMG varied significantly with clinical test position. Athletes with previous groin injury had a significant fall in some EMG outputs.

To determine whether therapeutic exercise can improve the timing of muscle onset following musculoskeletal pathology, and examine what exercise prescription parameters are being used to achieve these effects. ⋯ Therapeutic exercise training is likely to improve muscle onset timing. Additionally, isolated muscle training appears to be the best exercise mode to use to achieve these effects.

Ankle injuries are common in sporting activities with damage to the inferior tibiofibular ligaments being notable for their resultant disability and prolonged recovery. ⋯ An appreciation for the mechanism of injury and a careful examination can distinguish these injuries from other forms of ankle instability. Proper recognition and immediate attention to the unique complexities of this joint can minimize morbidity and prevent a delayed return to sports.
