“…This finding is significant because of the role of quadriceps strength in daily function. Quadriceps weakness negatively effects mobility [14,15,28], which may help explain why other researchers have found difficulties with functional performance after THA. Despite the fact that significant functional differences were not seen in our data, possibly related to small sample size, several studies have confirmed the presence of functional deficits and difficulty walking after THA.…”

Background Patients undergoing total hip arthroplasty (THA) often are satisfied with the decrease in pain and improvement in function they achieve after surgery. Even so, strength and functional performance deficits persist after recovery, but these remain poorly characterized; knowledge about any ongoing strength or functional deficits may allow therapists to design rehabilitation programs to optimize recovery after THA. Questions/purposes The purposes of this study were to (1) evaluate postoperative muscle strength, function, and quality of life during the first year after THA; and (2) compare strength and function in patients 1 year after THA with a cohort of healthy peers. Methods Twenty-six patients undergoing THA were assessed 1, 3, 6, and 12 months postoperatively, and 19 adults with no hip pathology were tested as a control group. Isometric muscle strength (hip flexors, extensors, abductors, knee extensors, and flexors), functional performance (stair climbing, five times sit-to-stand, timed-up-and-go, 6-minute walk, and single-limb stance tests), and selfreported function (Hip Disability and Osteoarthritis Score, SF-36, and UCLA activity score) were compared. Results One month after THA, patients had 15% less hip flexor and extensor torque, 26% less abductor torque, 14% less knee extensor and flexor torque, and worse performance on the stair climbing, timed-up-and-go, single-limb stance, and 6-minute walk. Compared with healthy adults, patients 12 months after THA had 17% less knee extensor and 23% less knee flexor torque; however, the functional testing (including stair climbing, five times sit-to-stand, and the 6-minute walk) showed no significant differences with the patient numbers available between individuals undergoing THA and healthy control subjects. SF-36 Physical Component Scores, although significantly improved from preoperative levels, were significantly worse than healthy adults 1 year after THA (p \ 0.01).

“…Some activities of daily life, such as shopping and cleaning the house, involve the ability to climb and descend steps, incline, crouch, and kneel down (3,17,29). Limitations in performing these functions considerably restricts the elderly's life activity and social participation (3,17).…”

“…Many motor skills are neglected during the process of aging, restricting daily life activities (3,18). Considering that falls present a multifactorial range (9), the concern with the fear of falling in elderly people exponentially limits the performance of usual tasks that demand multiple interactions of the sensorimotor system (6).…”

“…The TUG evaluates functional mobility and is a test widely used for the elderly population. This measure has high reproducibility and validity in the population of interest, because it effectively evaluates the balance and mobility of elderly people (3,18,26). This assessment consists of recording the time to rise from a chair, walk three meters (or 10 steps), turn around, walk back to the chair, and sit down, everything in the usual speed (26).…”

“…The most affected muscle groups are the lower limbs, such as knee extensors; plantar flexors and ankle dorsiflexors; and hip flexors and extensors (1,3,14). They limit elderly people from performing simple tasks such as rising from a chair, walking, climbing stairs, and inclining (1,9,3). Muscle weakness and fear of falling have increased the number of falls in the elderly population (1).…”

Introduction: Falls are among the most common and serious problems facing elderly women. Falling is associated with increased mortality, morbidity, reduced functioning, loss of independence and hospitalization. Objective: The aim of this study was to investigate the association among fear of falling, muscle strength, and functional abilities in community-dwelling elderly women. Methods: Forty-nine elderly women (70.57 ± 5.59 years) participated in this study. Records of falls, self-efficacy associated with falls (FES- I

Decreased Muscle Strength Relates to Self-Reported Stooping, Crouching, or Kneeling Difficulty in Older Adults

Abstract: Decreased muscle strength, particularly when normalized for body size, predicts SCK difficulty. These data emphasize the importance of strength measurement at multiple levels in predicting self-reported functional impairment.
