Maximal force production per unit of muscle mass (muscle quality, or MQ) has been used to describe the relative contribution of non-muscle-mass components to the changes in strength with age and strength training (ST). To compare the influence of age and gender on MQ response to ST and detraining, 11 young men (20-30 years), nine young women (20-30 years), 11 older men (65-75 years), and 11 old...

[Purpose] To investigate the relationship between isokinetic knee muscle strength and kinematic, kinetic and spatiotemporal gait parameters of patients with multiple sclerosis (MS). [Subjects and Methods] Twenty-nine MS patients (mean age 31.5±6.5) were investigated in this study. The isokinetic knee muscle strength and gait parameters of MS patients with moderate and severe disability, as dete...

STUDY DESIGN Randomized clinical trial. OBJECTIVES To determine if females with patellofemoral pain syndrome (PFPS) who perform hip strengthening prior to functional exercises demonstrate greater improvements than females who perform quadriceps strengthening prior to the same functional exercises. BACKGROUND Although PFPS has previously been attributed to quadriceps dysfunction, more recent...

Background The study was designed to evaluate and compare the effectiveness of 12-week open, closed and combined kinetic-chain exercises (OKCE, CKCE and CCE) on quadriceps muscle strength and thigh girth of patients with knee osteoarthritis (OA). Method The randomized clinical trial involved ninety-six consecutive patients with knee OA who were randomly assigned to one of OKCE, CKCE or CCE gr...

[Purpose] To assess the effect of hamstring and quadriceps strengthening exercises on pain intensity, gait velocity, maximum isometric strength, and activities of daily living of patients with knee osteoarthritis (OA). [Subjects and Methods] A total of 20 patients with knee OA, 50 to 65 years of age (57.65 ± 4.78 years), received hot packs, strengthening exercises for the quadriceps and the ham...

BACKGROUND the study of factors associated with age-related gait decline may assist in developing methods to preserve mobility in older people. OBJECTIVE to examine the associations between sensorimotor factors relevant to ageing and gait in the general older population. DESIGN cross-sectional population-based study. METHODS participants aged 60-86 years (n = 278) were randomly selected u...

BACKGROUND Adequate analgesia and early rehabilitation is necessary for arthroscopic anterior cruciate ligament reconstruction (A CLR) surgery. OBJECTIVE To compare analgesia and quadriceps strength after femoral nerve block (FNB) with intra-articular infiltration (IA) using 0.25% bupivacaine for ACLR with patella tendon graft. MATERIAL AND METHOD Forty patients were randomized to receive F...

OBJECTIVES To ascertain whether detailed isokinetic knee muscle testing reflects the results of other functional measurements in footballers and to look for any correlations between quadriceps tendon thickness and knee strength. METHODS Ultrasonographic evaluation of the quadriceps tendon (Hitachi EUB-405), isokinetic knee testing (Biodex System 3), and sprint measurements using telemetric ph...

BACKGROUND AND OBJECTIVES Femoral nerve block (FNB), a commonly used postoperative pain treatment after total knee arthroplasty (TKA), reduces quadriceps muscle strength essential for mobilization. In contrast, adductor canal block (ACB) is predominately a sensory nerve block. We hypothesized that ACB preserves quadriceps muscle strength as compared with FNB (primary end point) in patients afte...
