We compared differences in isometric strength between older adults who have undergone elective unilateral total hip arthroplasty (THA) and completed rehabilitation with a population of community-dwelling older adults who have not had THA. The study was a cross-sectional design, and 22 unilateral THA subjects and 38 community-dwelling older adults participated. THA subjects received on average 1...

[Purpose] This study aimed to investigate the relatedness, reliability, and validity of isometric muscle strength measurements of hip abduction and abduction with an external hip rotation in a bent-hip position using a handheld dynamometer with a belt. [Subjects and Methods] Twenty healthy young adults, with a mean age of 21.5 ± 0.6 years were included. Isometric hip muscle strength in the subj...

Isometric evaluation of hip and knee muscle strength can be a useful objective assessment tool in the clinic and may be preferred over other forms of dynamic muscle testing, such as isokinetic assessment or variable-resistance weight-lifting. Assessment of isometric strength with use of a handheld dynamometer requires little skill and is easily administered, relatively inexpensive, valid, relia...

BACKGROUND The extent to which muscle length affects force production in paretic lower limb muscles after stroke in comparison to controls has not been established. OBJECTIVES To investigate knee flexor strength deficits dependent on hip joint position in adults with hemiparesis and compare with healthy controls. METHOD a cross-sectional study with ten subjects with chronic (63±40 months) h...

CONTEXT Lower extremity (LE) weakness might be associated with altered mechanics during weight bearing in subjects with patellofemoral pain syndrome (PFPS). OBJECTIVE To analyze LE strength, mechanics, and the association between these variables among women with and without PFPS during a simulated athletic task. DESIGN Case control. SETTING Motion-analysis laboratory. SUBJECTS 20 women ...

Background: The present study examined the relationship between muscle strength and range of motion in the lower extremity, and balance and risk of falling in the elderly. Methods: This cross-sectional study was conducted on healthy elderly (mean±SD age: 65.64±4.95 y) in Rasht City, Iran. The study participants were 65 healthy male elderly who met the stud inclusion criteria. They were selecte...

At a minimum of one year after operation, we studied 64 patients with 86 total hip arthroplasties (THA) by standard anteroposterior hip and pelvic radiographs and measurement of range of motion and of isometric abduction strength. The femoral offset correlated positively with the range of abduction (p = 0.046). Abduction strength correlated positively with both femoral offset (p = 0.0001) and t...

[Purpose] The aim of present study was to investigate the effects of isometric quadriceps exercise on muscle strength, pain, and function in knee osteoarthritis. [Subjects and Methods] Outpatients (N=42, 21 per group; age range 40-65 years; 13 men and 29 women) with osteoarthritis of the knee participated in the study. The experimental group performed isometric exercises including isometric qua...
