Efficacy of 2 non-weight-bearing interventions, proprioception training versus strength training, for patients with knee osteoarthritis: a randomized clinical trial.

Study Design: Randomized clinical trial.

Objective: To investigate the clinical and functional efficacy of 2 different non-weight-bearing exercise regimens, proprioceptive training (PrT) versus strength training (ST), for patients with knee osteoarthritis (OA).

Background: Both strength and proprioceptive training are important interventions for individuals with knee OA.

Differences in sonographic characteristics of the vastus medialis obliquus between patients with patellofemoral pain syndrome and healthy adults.

Background: There is controversy regarding the relationship between patellofemoral pain syndrome (PFPS) and insufficiency of the vastus medialis obliquus (VMO). The conventional clinical practice of VMO strengthening for PFPS has been challenged for lack of evidence. The purpose of this study was to observe the difference in sonographic findings of the VMO between patients with PFPS and healthy adults.

Effects of weight-bearing versus nonweight-bearing exercise on function, walking speed, and position sense in participants with knee osteoarthritis: a randomized controlled trial.

Objective: To investigate whether weight-bearing (WB) exercise enhances functional capacity to a greater extent than nonweight-bearing (NWB) exercise in participants with knee osteoarthritis.

Design: Randomized controlled trial.

Setting: Kinesiology laboratory.

The effects of quadriceps contraction on different patellofemoral alignment subtypes: an axial computed tomography study.

Study Design: Controlled laboratory study.

Background: The effect of quadriceps contraction on patellar alignment in patients with patellofemoral pain syndrome (PFPS) is debated and may vary based on patellar alignment subtypes measured with the quadriceps relaxed.

Objectives: To determine if the effects of quadriceps contraction on patellar alignment differs (1) with respect to patellar alignment subtype in individuals with PFPS and (2) between symptomatic and asymptomatic knees in individuals with unilateral PFPS.

Surplus value of hip adduction in leg-press exercise in patients with patellofemoral pain syndrome: a randomized controlled trial.

Background: A common treatment for patients with patellofemoral pain syndrome (PFPS) is strength (force-generating capacity) training of the vastus medialis oblique muscle (VMO). Hip adduction in conjunction with knee extension is commonly used in clinical practice; however, evidence supporting the efficacy of this exercise is lacking.

Objective: The objective of this study was to determine the surplus effect of hip adduction on the VMO.

Association between sonographic morphology of vastus medialis obliquus and patellar alignment in patients with patellofemoral pain syndrome.

Study Design: Descriptive, correlational, anatomical laboratory study.

Objectives: To investigate the association between the morphology of the vastus medialis obliquus (VMO) and patellar alignment in patients with patellofemoral pain syndrome (PFPS).

Background: It has long been presumed that PFPS results from patellar malalignment.

Efficacy of a target-matching foot-stepping exercise on proprioception and function in patients with knee osteoarthritis.

Study Design: A randomized clinical trial design.

Objective: To investigate the efficacy of high, repetitive, target-matching foot-stepping exercise (TMFSE) performed in a sitting position on proprioception, functional score, and walking velocity for patients with knee osteoarthritis (OA).

Background: Researchers have suggested that exercises to address knee OA should include proprioceptive training.

Different effects of femoral and tibial rotation on the different measurements of patella tilting: An axial computed tomography study.

Background: The various measurements of patellar tilting failed to isolate patellar tilting from the confounding effect of its neighboring bone rotation (femoral and tibial rotation) in people sustaining patellofemoral pain (PFPS). Abnormal motions of the tibia and the femur are believed to have an effect on patellofemoral mechanics and therefore PFPS. The current work is to explore the various effects of neighboring bone rotation on the various measurements of patellar tilting, through an axial computed tomography study, to help selecting a better parameter for patella tilting and implement a rationale for the necessary intervention at controlling the limb alignment in the therapeutic regime of PFPS.

Effects of anterolateral minimally invasive surgery in total hip arthroplasty on hip muscle strength, walking speed, and functional score.

We conducted this study to observe the difference in muscle strength and walking speed between patients who underwent total hip arthroplasty (THA) in whom an anterolateral mini-incision technique was used and those in whom a conventional approach was used. Fifty-three patients who underwent a mini-incision THA were matched by diagnosis, sex, age, period elapsed since surgery (which ranged from 6 months to 4 years), weight, and height to 53 patients who underwent THA using the conventional anterolateral approach. During the first year after surgery, patients with the mini-incision THA had significantly better hip muscle strength, walking speed, and functional score (P < .

Comparison of proprioceptive functions between computerized proprioception facilitation exercise and closed kinetic chain exercise in patients with knee osteoarthritis.

Aim: The aim of this study was to compare proprioceptive function between computerized proprioception facilitation exercise (CPFE) and closed kinetic chain exercise (CKCE) for knee osteoarthritis.

Design: Randomized-controlled.

Setting: Kinesiology laboratory.

Effects of age and sex on the results of an ankle plantar-flexor manual muscle test.

Background And Purpose: The ability to perform 20 or more one-leg heel-rises is considered a "normal" grade for muscle strength (force-generating capacity of muscle) of the ankle plantar flexors, regardless of age and sex. Because muscle strength is closely related to age and sex, the "normal" test criterion was re-evaluated in different groups categorized by age and sex.

Subjects And Methods: One hundred eighty sedentary volunteers (21-80 years of age) without lower-limb lesions performed as many repetitions of one-leg heel-rise as possible.
