Muscle impairments associated with knee osteoarthritis (OA) are the primary underlying cause of functional limitations. Understanding extent muscle impairments, its relationship physical function and disease progression, evidence behind exercise therapy that targets is crucial.An electronic search for relevant articles using MEDLINE CINHAL databases up to September 2011 was performed. In addition search, retrieved were searched manually studies.Quadriceps, hamstrings, hip muscles...

Abstract After unilateral total knee arthroplasty (TKA), osteoarthritis (OA) in the non‐operated often progresses. The altered gait mechanics exhibited by patients after TKA increase loading on and predispose it to disease progression. Therefore, our objective was examine potentially detrimental changes frontal plane kinetics kinematics during walking who underwent TKA. Thirty‐one subjects 6 months TKA, 24 1 year 20 control were recruited. All 3D analysis. In groups, had a higher adduction...

Because people with total knee arthroplasty (TKA) have persistent functional limitations and disability, identifying modifiable risk factors for disability is warranted. Before surgery, pervasive lower extremity muscle weakness. The fact that hip abductor strength often not targeted in postoperative rehabilitation may contribute to limitations.Study objectives were: (1) examine the reliability of handheld dynamometry (HHD) measuring (2) determine whether contributes physical function beyond...

Background/Objective: Inconsistencies exist regarding the exact multidimensional structure underlying Fear-Avoidance Beliefs Questionnaire (FABQ), with no prior study examining internal of Arabic FABQ. This aimed to examine validity evidence FABQ in patients low back pain (LBP), based on two sources: (dimensionality and reliability) relations other variables (i.e., intensity disability). Methods: Participants (N = 112) LBP were recruited from physical therapy clinics. Data collected through...

Methods: Standard forward backward translation followed by expert committee review, then preliminary testing carried out produce final version LEFS (LEFS-Ar). test–retest reliability, error, internal consistency construct validity LEFS-Ar were examined extremity (N =...

The purpose of this study was to translate and cross-culturally adapt the UEFI into Modern Standard Arabic language examine its psychometric properties among patients with upper extremity musculoskeletal disorders.Translation cross-cultural adaptation were done following Beaton's guidelines. Internal consistency, test-retest reliability, measurement error floor ceiling effects for tested 109 disorders. Construct validity also examined.Translation processes generally smooth no major issues....

Purpose The Multiple Sclerosis Impact Scale-29 (MSIS-29) is a patient self-reported outcome (PRO) that measures patients' quality of life, and it divided into two sub-scales for the physical (PHYS) psychological (PSYCH) domains. This study aimed to translate MSIS-29 Arabic, cross-culturally adapt it, examine its psychometric properties.

Background: Early mobility (EM) is vital in the intensive care unit (ICU) to counteract immobility-related effects. A multidisciplinary approach key, as it requires precise initiation knowledge. However, physicians’ understanding of EM adult ICU settings remains unexplored. This study was conducted investigate knowledge and clinical competency physicians working ICUs toward EM. Methods: cross-sectional enrolled 236 assess their rigorously designed survey comprising 30 questions across...
