BACKGROUND AND OBJECTIVES Adductor canal block (ACB) has been suggested as an analgesic alternative to femoral nerve block (FNB) for procedures on the knee, but its effect on quadriceps motor function is unclear. We performed a randomized, blinded study to compare quadriceps strength following adductor canal versus FNB in volunteers. Our hypothesis was that quadriceps strength would be preserve...

BACKGROUND In adult patients with developmental hip dysplasia, a surgical procedure (triple innominate osteotomy) of the pelvic bone can be performed to rotate the acetabulum in the frontal plane, establishing better acetabular coverage. Although common clinical hip scores demonstrate significant improvements after surgery, they provide only overall information about function. The purpose of th...

Many female college students in South Corea suffer from postural problems and deformities in their lower extremities. In particular, many females exhibit knee valgus or varus. These problems can arise from a variety of causes, from the use of elevated heels, to years of carrying heavy backpacks, and muscle imbalance. There are many different types of exercises to address these problems, but iso...

Autism represents a disorder of neural development characterized by 3 features including deficit in social communication, inflexibility of speech and behavior, and stereotyped movements. The prevalence of this disorder has been reported about 1.5 per 100 individuals in Iran. Individuals with ASDs are susceptible to weakness in balance and stability and also postural deformities. Thus, the pur...

Rhythmic Gymnastics (RG) is a competitive sport that due to its aesthetic and technical requirements makes athletes seek to maximize their technical performance. Elements inherent to the sport are based on movements of hip extension, flexion and abduction, which explain the need for producing considerable levels of strength in different muscle lengths and speeds. The aim of the study was to eva...

PURPOSE To examine whether normalized quadriceps and hamstring strength would predict quadriceps and hamstring muscle activation amplitudes and whether these neuromuscular factors would predict knee kinematics and kinetics during a drop jump task. METHODS Thirty-nine females and 39 males were measured for isometric quadriceps and hamstring strength and were instrumented to obtain surface elec...

CONTEXT Rapid deceleration during sporting activities, such as landing from a jump, has been identified as a common mechanism of acute knee injury. Research into the role of potential sex differences in hip abductor function with lower extremity kinematics when landing from a jump is limited. OBJECTIVE To evaluate sex differences in hip abductor function in relation to lower extremity landing...

OBJECTIVE To evaluate test methods for hip and knee muscle weakness and gait disturbance. DESIGN Test-retest. SETTING Orthopedic university clinic. PARTICIPANTS Ten young (age, 36+/-6 y) and 13 elderly (age, 69+/-8 y) healthy volunteers and 11 patients (age, 69+/-8 y) with unilateral hip osteoarthritis (OA) were tested for muscular strength. Twenty-five volunteers (age, 42+/-14 y) underwe...

Aim of the Study: The aim of the study was to determine the relationship between the performance of six therapeutic exercises and muscle strength with standing ability in children with spastic diplegic cerebral palsy. Methodology: 50 subjects with spastic CP with ability to stand with one finger support or without support were randomly selected. The total standing duration without support or wi...
