Background: Knee osteoarthritis (OA) is a debilitating condition that leads to functional limitations. Self-reported questionnaires and performance-based tests are tools commonly used for measuring physical function. Objectives: (1) To evaluate the impact of end-stage knee OA on functional outcomes and examine the association between self-report...

Background: Knee osteoarthritis (OA) is a common and disabling disease among the elderly population. The optimal conservative treatment for knee OA is not well established. Objective: This study aimed to assess the effectiveness of pulsed electromagnetic field (PEMF) combined with progressive resistance exercise (PRE) in improving physical funct...

Objective Of the present study was to evaluate the impact of end-stage knee OA on patient’s perception of their functional abilities and quality of life (QoL) using the self-reported questionnaire; the Knee Injury and Osteoarthritis Outcome Score (KOOS), and to determine the contribution of knee pain on patient’s perceived outcomes. Methods Patien...

Purpose The Central Sensitization Inventory (CSI) is a tool that aid in identifying symptoms associated with nociplastic pain. The aim of this study is to adapt CSI to Arabic language, and to examine its psychometric properties. Methods Adaptation process followed recommended guidelines. Participants with self-reported chronic pain completed a web...

Objectives: To explore whether quadratic model will better estimate the relationship between aging and thigh tissue composition in a cohort that range in age from young to older adults. Methods: 51 healthy subjects participated in this investigation. All subjects underwent CT imaging for the thigh. Cross-sectional area of the fat and muscular tissu...

Aims: To report estimates of the reliability and agreement of a new method for measuring the femoral Neck-shaft angle in the Jordanian population. The neck-shaft angle is an important anatomical indicator in orthopedics of the hip. While there are different approaches to measuring the neck-shaft angle in the literature, there is no agreement on the...

The purposes of this study were first to examine the association between aging and both the magnitude and asymmetry in the femoral neck-shaft angle (NSA). The second purpose was to determine the effects of both the magnitude and NSA asymmetry on the performance of functional activities in healthy individuals. Fifty-one subjects participated in this...

Objective: Performance-based measures of function are used in both clinical and research settings. During functional testing procedures, participants’ performance change from one trial to another. Therefore, there is a need to know how much change in performance is considered a real change from one trial to another during the same testing visit. Me...

[Purpose] Literature has revealed age-related changes in body regional tissues in the form of reduced muscle size and increased adipose tissue. There is also a decline in the performance of physical function with aging. The aim of this study is to examine the partial and part correlations between physical performance and thigh tissue composition am...

[Purpose] To determine the relationships of the quadriceps rate of torque development and the time to peak torque with the physical function of the elderly. [Subjects and Methods] Twenty-one subjects participated in this study. Quadriceps strength was measured using isometric and isokinetic torque tests. Time to peak torque and rate of torque devel...

Aging is associated with structural changes in skeletal muscles. One such change is loss of muscle mass. Muscle fiber atrophy is another structural transformation. Muscle fiber atrophy is selective to type II muscle fibers. The reduced mass of aging muscles has functional consequences like reduced performance of daily activities. Although exercise...

Purpose: Previous researchers found that frontal plane laxity can alter the relationship between strength and physical function in subjects with knee OA. However, the devices used in these studies measured the amount of tibial abduction and adduction with respect to the femur and did not provide direct measurement of articular surface displacements...
