The force steadiness capabilities of the hip abductors and ankle dorsiflexors can explain a significant amount of the variance in postural sway during four types of standing balance tests. Control over balance, as well as force steadiness, generally worsens with aging, although the latter can be improved with unique training interventions. The purpose of our study was to assess how tempo-controlled, light-load resistance training of the hip abductors and ankle dorsiflexors influences performance in clinical movement tests, postural sway, muscle strength, and force steadiness in older adults. Participants (n = 28, 70 ± 7 years, 8 men) completed nine training sessions for either the hip abductors or ankle dorsiflexors in the nondominant leg. Training involved lifting a load equal to 15% of the maximal force achieved during an isometric contraction. Linear mixed-effects models revealed no changes (p > 0.05) in Sit-To-Stand test, Timed Up-and-Go test, maximal voluntary contraction (MVC) torque, or postural sway from before to after either training intervention. Only the dorsiflexor group significantly improved nondominant leg dorsiflexion force steadiness, but this did not translate to any other tasks. However, absolute and relative measures of MVC torque and force steadiness of the hip abductors and ankle dorsiflexors in the dominant and nondominant legs could predict sway-area rate in each of the four standing balance conditions. The responsiveness of leg muscles to light-load steadiness training in older adults appears to depend on the type of exercises performed during the intervention.

Background: Low back pain (LBP) accompanied by sciatica is a widespread musculoskeletal issue with multifactorial etiology, impacting individuals across various demographics. Conservative treatments, notably physiotherapy, are key in managing LBP with sciatica, with neural mobilization techniques emerging as beneficial adjuncts.
Aim: This research aims to assess the effectiveness of utilizing the sciatic slider technique (SST) in both supine and slump positions, compared to conventional physiotherapy alone, in alleviating pain severity, improving lumbar flexibility, lumbar lordosis, lower limb muscle strength, and functional ability in patients with LBP associated with sciatica.

Objective: Total hip arthroplasty through the Hardinge approach damages the hip abductor muscles. MRI can be used to assess adverse postoperative events. In this prospective randomized controlled trial, we evaluated MRI findings and whether platelet-rich plasma affected postoperative healing of the gluteal muscles (gluteus medius and minimus).

: Legg-Calvé-Perthes disease (LCPD) presents challenges in treatment due to its varied course and unclear etiology. This study aimed to evaluate the efficacy of combining proximal femoral varus osteotomy (PFVO) with a modified trochanteric flip osteotomy to address biomechanical consequences and improve hip abductor muscle strength. : We present a modified approach combining PFVO with a trochanteric flip osteotomy.

Context: Tendon abnormalities on imaging are commonly observed in individuals with Achilles tendinopathy. Those abnormalities can also be present in asymptomatic individuals, which is an important risk factor for developing tendon symptoms. Ballet dancers are particularly vulnerable due to the high loads placed on their Achilles tendons.

Objective: Validated patient-reported outcome measures for patients with hip-abductor tendon pathology are lacking. Recent studies indicate that the Copenhagen Hip and Groin Outcome Score (HAGOS), in the original or the revised scoring format, and the Oxford Hip Score (OHS) may be relevant for use in patients with hip-abductor tendon pathology. The objective of this study was to assess the validity of the Danish version of the HAGOS, the revised HAGOS, and the OHS psychometrically in patients with hip-abductor tendon pathology.
