BACKGROUND Selective atrophy of hamstring components may result from muscle strain or graft harvesting for anterior cruciate ligament reconstruction. Assessment and rehabilitation that specifically targets medial (MH) or lateral (LH) hamstring components may improve patient outcomes. The purpose of this study was to evaluate effects of volitional tibial rotation medially (MR) versus laterally (...

Purpose: This study investigated the influence of static stretching exercises on specific exercise performances. Methods: Thirty-eight volunteers participated in this study. The stretching group (STR) consisted of ...

background: posttraumatic and/or postsurgical knee stiff ness is one of the orthopedic complications which is difficult to be treated and can affect individual’s life negatively. the aim of this study is to investigate the results of quadricepsplasty in patients with knee stiff ness resulted from femoral fracture. materials and methods: this is a cross-sectional study on all patients with femor...

INTRODUCTION Peripheral muscle strength has been little explored in the literature in the context of cardiac rehabilitation. OBJECTIVE To evaluate the peripheral muscle strength of patients undergoing elective cardiac surgery. METHODS This was a longitudinal observational study. The peripheral muscle strength was measured using isometric dynamometry lower limb (knee extensors and flexors) a...

OBJECTIVE To analyse the influence of chronic pain on muscle strength. DESIGN Muscle strength of patients with unilateral nonspecific chronic pain, in an upper or lower limb, were measured according to a standardized protocol using a hand-held dynamometer. Before and after muscle strength measurement, a visual analogue scale for pain intensity was assessed. RESULTS Forty patients were measu...

BACKGROUND One of the rationales behind using strength training in the treatment of adolescents with Patellofemoral Pain (PFP) is that reduced strength of the lower extremity is a risk factor for PFP and a common deficit. This rationale is based on research conducted on adolescents >15 years of age but has never been investigated among young adolescents with PFP. OBJECTIVES To compare isometr...

The aims of the study were to investigate the differences in kinematics and kinetics between the dominant and nondominant leg during single-leg jumps without arm swing, and to determine the relationship between bilateral asymmetry in isokinetic knee strength and the single-leg jump. Isokinetic knee strength and single-leg jump kinematics and kinetics were measured in 11 male participants. The b...

OBJECTIVE To describe the profile of joint mobility and grip and pinch strength of MPS VI patients and to correlate this with urinary excretion of glycosaminoglycans (GAGs), ARSB activity, and the distance covered in a 6-minute walking test (6MWT). METHODS This was an observational study of 28 patients with MPS VI, who had not undergone specific treatment. All patients were assessed for ampli...

BACKGROUND The reproducibility of day-to-day testing of isokinetic concentric and eccentric muscular actions among adolescent basketball players aged 14 to 16 years and relationships of mean within-subject variation in two isokinetic testing sessions with chronological age, biological maturation (estimated age at peak height velocity), training experience, body size, lower-body morphology, and ...
