Pelvic floor muscle (PFM) force and coordination are related to urinary incontinence severity and to sexual satisfaction. Health professionals frequently combine classic PFM exercises with hip adduction/abduction contraction to treat these disorders, but the real benefits of this practice are still unknown. Based on a theoretical anatomy approach whereby the levator ani muscle is inserted into ...

BACKGROUND Patients with hip osteoarthritis (OA) typically suffer joint pain, and often experience muscular weakness. We hypothesized that substantial atrophy would manifest in multiple muscle groups along the affected limb, resulting in severe muscle dysfunction. PATIENTS AND METHODS We assessed 22 elderly patients with unilateral OA for maximal voluntary isometric strength of hip and knee m...

OBJECTIVE To investigate the reliability and agreement of measures of lower extremity muscle strength, power and functional performance in patients with hip osteoarthritis at different time intervals, and to compare these with the same measures in healthy peers. DESIGN Intra-rater test-retest separated by 1, 2, or 2.5 weeks in patients, and 1 week in healthy peers. SUBJECTS Patients with hi...

PURPOSE To evaluate the relationship between posterolateral reconstruction, abductor muscle strength, and femoral offset following total hip arthroplasty. METHODS Of 28 patients (56 limbs) we assessed, 12 underwent posterolateral reconstruction (reconstruction group) and 16 did not (non-reconstruction group). Isometric abductor muscle strength was measured with a handheld dynamometer. Each pa...

Futsal is one of the most harmful sports due to its great physical demands. The asymmetries have been proposed as important risk factors suffering an injury. However, no study has analysed relationship between neuromuscular assessment and implication on likelihood injuries comparing male female players. purpose was analyse fitness differences elite futsal players (both female) who suffered inju...

QUESTION What is the feasibility and effectiveness of a novel weight-bearing strengthening program compared with that of a traditional non-weight-bearing strengthening program for older inpatients undergoing rehabilitation? DESIGN Randomised, controlled trial with concealed allocation, assessor blinding, and intention-to-treat analysis. PARTICIPANTS Eighty-eight inpatients (11% loss to foll...

CONTEXT Very few authors have investigated the relationship between hip-abductor muscle strength and frontal-plane knee mechanics during running. OBJECTIVE To investigate this relationship using a 3-week hip-abductor muscle-strengthening program to identify changes in strength, pain, and biomechanics in runners with patellofemoral pain syndrome (PFPS). DESIGN Cohort study. SETTING Univers...

The purpose of the present study was to determine the extent to which lower extremity muscular strength is an independent predictor of proximal femur BMD in healthy older adults. It was hypothesized that the BMD of the proximal femur in older adults would not be related to the maximum voluntary isometric strength of the hip, knee, and ankle muscles after adjusting for the influence of body weig...

background: the aim of this study was to investigate muscle damage indicators and electromyography activities of quadriceps muscles at 25° of hip flexion in untrained healthy females after an eccentric exercise induced muscle fiber damage.   methods : a total of 14 healthy females participated in this pre-experimental study. the subjects performed maximal eccentric quadriceps contractions at 25...

This study examined the role of high forces versus metabolic cost in the adaptations following strength training. Ten young, healthy male and female subjects trained one leg using concentric (CL) and the other using eccentric (EL) contractions of the quadriceps muscle for 20 weeks. EL used weights which were 35% higher than those used for CL. Isometric strength, and the length:tension and force...
