Understanding muscle response to exercise is critical for optimizing training strategies. This study investigated the effects of dorsiflexion and plantar flexion exercises on T2* values in the tibialis anterior (TA) and soleus (SOL) muscles and explored their relationship with muscle cross-sectional area (MCA), strength, and perceived exertion. Forty participants were divided into two exercise protocols: 30 performed dorsiflexion, 16 performed plantar flexion, and 6 completed both.

The prevalence of multiple falls is higher in older women, and knee pain is associated with multiple falls in women; thus, it is important to detect individuals at risk of fractures among women with knee osteoarthritis. We aimed to clarify the association between knee osteoarthritis and the quantitative ultrasound (QUS) parameter, and investigate the clinical relevance of the QUS parameter with osteoarthritis-related characteristics in women with knee osteoarthritis. This was a cross-sectional study.

Research Question: What are the differences between trunk movement asymmetries before and after total knee arthroplasty (TKA) and associations between the changes in trunk movement asymmetry and quadriceps strength asymmetry?
Methods: In this prospective cohort study, 27 patients (mean age, 71.0 years; women, 85.
Objective: Gait variability changes before and after total hip arthroplasty are unclear. This study aimed to investigate gait variability changes in hip osteoarthritis patients before and after total hip arthroplasty and to examine the relationships between gait variability changes and hip function.
Design: Twenty-three female patients with hip osteoarthritis (61.
Background: Patients who undergo total knee arthroplasty (TKA) may experience disease-specific problems, including decline in motor function and intense pain, which may result in disease-specific anxiety. This study aimed to investigate disease-specific anxiety at discharge, and any association between anxiety and functional outcomes following TKA.
Methods: The study prospectively included 129 patients who had undergone TKA.
: The purpose of this study was to compare the recovery of mobility and self-efficacy following total knee arthroplasty (TKA) between the 5-day and the 28-day protocol. This prospective cohort study was carried out at two hospitals.: In total, 104 patients who underwent TKA were enrolled.

Although patients with knee osteoarthritis (OA) have shown restricted life-space mobility, total knee arthroplasty (TKA) does not improve it beyond preoperative levels. Life-space mobility after TKA was influenced by self-efficacy for walking tasks; thus, an intervention to improve self-efficacy for walking tasks may contribute to better life-space mobility.

Although many reports have shown that exercise training improves motor function, it is unclear whether a group-based and short-term health promotion intervention will improve motor function in older adults.
Aims: This study aimed to examine the effectiveness of a short-term health promotion intervention on motor function in community-dwelling older adults.
[Purpose] This study aimed to develop a tablet app that emulates paper questionnaires used in clinical care, and to verify the difference between the utility of tablet survey methods and paper questionnaire methods with elderly people. [Subjects and Methods] A tablet app was developed in the Java language. A questionnaire was provided to 30 community-dwelling elderly people.

The aim of this study was to determine whether abnormal trunk motion persisted after THA using accelerometry. A total of 24 female patients (61.

Background The extent to which group-based exercise (G-EXE) improves knee range of motion (ROM), quadriceps strength, and gait ability is similar to that of individualized exercise (I-EXE) at 6 weeks and 8 months after total knee arthroplasty (TKA). However, the benefits of G-EXE for patients during the acute recovery phase after TKA remain unclear.
View Article and Find Full Text PDFRestricted mobility is a major issue for individuals with knee osteoarthritis (OA). Total knee arthroplasty (TKA) is expected to improve mobility in people with knee OA by alleviating pain and improving walking ability. The present study aimed to describe the time course of mobility after TKA and to identify the factors affecting mobility after TKA.

Methods: A total of 20 patients with type 2 diabetes and 20 patients without diabetes matched for age, body mass index, knee range of motion, and muscle strength at baseline participated in this study. We examined knee range of motion and muscle strength and assessed functional activities using the new Knee Society Score questionnaire for each patient 1 month preoperatively and at 6 and 12 months postoperatively.
This study aimed to determine gait ability at hospital discharge in patients undergoing total knee arthroplasty (TKA) as an indicator of the risk of falling. Fifty-seven patients undergoing primary TKA for knee osteoarthritis participated in this study. Gait variability measured with accelerometers and physical function including knee range of motion (ROM), quadriceps strength, walking speed, and the Timed Up and Go (TUG) test were evaluated preoperatively and at discharge from the hospital (1 month before and 5 days after surgery).

Design: A randomized controlled trial with two groups: a walking group and a control group.
Subjects: Forty older adults with knee osteoarthritis, 20 participants in each group.
