Impact of Preoperative Skeletal Muscle Quality on Functional Outcome in Total Hip Arthroplasty.

Objectives: To investigate the effect of preoperative muscle quality on functional outcomes after total hip arthroplasty (THA).

Design: Retrospective cohort study.

Setting And Participants: We included 426 patients who underwent primary THA between 2015 and 2022 to evaluate the relationship between preoperative muscle quality and 1-year functional outcomes following THA.

Predictors for the Knee Extension Strength at 2 Yrs After Total Knee Arthroplasty Using Regression Tree Analysis.

Objective: The aim of the study is to clarify the interactive combinations of clinical factors associated with knee extension strength 2 yrs after total knee arthroplasty.

Design: A retrospective cohort study was conducted on 264 patients who underwent total knee arthroplasty. Knee extension strength was assessed preoperatively, 3 wks, and 2 yrs after total knee arthroplasty.

Pre-stroke physical activity is associated with post-stroke physical activity and sedentary behavior in the acute phase.

This study investigated the link between pre-stroke and acute-stage physical activity (PA) and sedentary behavior. Forty individuals with stroke (aged 73.6 ± 8.

Association of physical activity with fatty infiltration of muscles after total hip arthroplasty.

Objective: This study aimed to investigate the association between muscle density as an indicator of fatty infiltration of lower extremity muscles and physical activity (PA) after total hip arthroplasty (THA) and identify the patient characteristics with high postoperative PA.

Methods: This study included 62 female patients who underwent THA for unilateral hip osteoarthritis. Muscle density of the gluteus maximus, gluteus medius, iliopsoas, and quadriceps muscles was measured using computed tomography (CT).

Interactive Combinations Between Gait Speed and Physical Function at Acute Phase Can Predict the Physical Activity at 2 Years After Total Knee Arthroplasty Using Classification and Regression Tree Analysis.

Objective: To clarify the interactive combinations of various clinical factors associated with physical activity (PA) at 2 years after total knee arthroplasty (TKA) using classification and regression tree (CART) analysis.

Design: A retrospective cohort study.

Setting: A single university hospital.

Effect of gait distance during robot training on walking independence after acute brain injury.

This study aimed to determine whether the distance of gait training using a hybrid assistive limb (HAL) is related to the improvement of walking independence in patients with acute brain injury. This was an exploratory, observational study. Thirty patients having hemiplegia (functional ambulation category, FAC score ≤2) with acute stroke or after brain tumor surgery were included.

A First View of the Effect of a Trial of Early Mobilization on the Muscle Strength and Activities of Daily Living in Mechanically Ventilated Patients With COVID-19.

Objective: To retrospectively investigate the effect of early mobilization on the muscle strength and activities of daily living in patients with COVID-19 under mechanical ventilation.

Design: This was a single-center, retrospective, observational study.

Setting: Inpatient rehabilitation care in Japan.

Association of Physical Activity and Nutritional Intake with Muscle Quantity and Quality Changes in Acute Stroke Patients.

Objectives: To evaluate longitudinally the muscle properties of acute stroke patients and examine the association between physical activity and nutritional intake.

Materials And Methods: This study enrolled 21 stroke patients (72.7±10.

Immediate family support is important to discharge home for cancer patient with bone metastasis after rehabilitation: A retrospective study.

The purpose of this study is to investigate the predictive factors of home discharge for rehabilitation patients with cancer bone metastasis.Cancer patients with bone metastasis who underwent rehabilitation between April 2014 and March 2017 were retrospectively enrolled. Data on discharge destination were collected from medical records as outcomes.

Effects of periodic robot rehabilitation using the Hybrid Assistive Limb for a year on gait function in chronic stroke patients.

Using a robot for gait training in stroke patients has attracted attention for the last several decades. Previous studies reported positive effects of robot rehabilitation on gait function in the short term. However, the long-term effects of robot rehabilitation for stroke patients are still unclear.

Effect of different trunk postures on scapular muscle activities and kinematics during shoulder external rotation.

Background: Shoulder external rotation at abduction (ER) is a notable motion in overhead sports because it could cause strong stress to the elbow and shoulder joint. However, no study has comprehensively investigated the effect of different trunk postures during ER. This study aimed to investigate the effect of different trunk postures on scapular kinematics and muscle activities during ER.

Greater Lumbar Extension During Dolphin Kick and Psoas Major Tightness in Swimmers With Low Back Pain.

Context: In competitive swimming, many swimmers experience low back pain (LBP). Lumbar hyperextension may cause LBP, and tight hip-flexor muscle may cause lumbar extension during swimming.

Objective: The purpose of this study was to clarify the features of the elastic moduli of the muscles and the lumbar extension when swimmers with LBP perform a dolphin kick (DK).
