A home-based low-intensity resistance exercise programme with supervision for secondary sarcopenia in a patient with established rheumatoid arthritis: A case report.

Patients with established rheumatoid arthritis (RA) are at risk of developing secondary sarcopenia. Both pharmacological and exercise interventions are essential for treatment. However, for such patients, exercise loads may lead to the progression of joint destruction and worsening of pain.

Comparative Study of Muscle Hardness during Water-Walking and Land-Walking Using Ultrasound Real-Time Tissue Elastography in Healthy Young People.

Compared with land-walking, water-walking is considered to be beneficial as a whole-body exercise because of the characteristics of water (buoyancy, viscosity, hydrostatic pressure, and water temperature). However, there are few reports on the effects of exercise in water on muscles, and there is no standard qualitative assessment method for muscle flexibility. Therefore, we used ultrasound real-time tissue elastography (RTE) to compare muscle hardness after water-walking and land-walking.

A cross-sectional survey of consistent rehabilitation through long-term care insurance in Japan: a questionnaire survey.

Unlabelled: There seems to be a lack of consistency of maintenance/community-based rehabilitation through long-term care insurance. We aimed to clarify whether consistent rehabilitation can be performed through long-term care insurance by questionnaires.

Materials And Methods: This study was a cross-sectional study in a nationwide survey among rehabilitation staff and care recipients who completed disease-specific rehabilitation and required maintenance/community-based rehabilitation through long-term care insurance.

Rehabilitation in the long-term care insurance domain: a scoping review.

Purpose: Since the enactment of the long-term care insurance (LTCI) act in 2000, the number of LTCI users has increased annually. However, evidence regarding what is being carried out as rehabilitation treatment under LTCI is lacking. In this study, a scoping review was performed to bridge this knowledge gap.

Effect of Foot Orthosis Treatment on Quality of Life in Secondary Sarcopenia Patients with Rheumatoid Arthritis-Related Foot Impairment.

Objectives: Patients with rheumatoid arthritis (RA)-related foot impairment have a high rate of sarcopenia. Treatment using a foot orthosis (FO) enables not only a reduction in pain while walking but also an increase in physical activity, helping to prevent further loss of muscle mass. However, the primary goal of treating RA is to maximize patients' long-term quality of life (QOL).

Prosthetic walking after bilateral transfemoral amputation in a patient with dilated cardiomyopathy: a case report.

In this study, we present a case of a 14-year-old adolescent boy who developed rhabdomyolysis and underwent bilateral transfemoral amputation after cardiopulmonary resuscitation for cardiac arrest because of dilated cardiomyopathy (DCM). Patients with bilateral transfemoral amputation have slower walking velocity and greater oxygen consumption during walking. Rehabilitation of such patients may be demanding especially if they have DCM, one of the major causes of advanced heart failure.

The Efficacy of Health Surveys and Polymerase Chain Reaction Tests Prior to Judo Tournaments During the COVID-19 Pandemic.

Background As of October 2021, sports activities require preventive measures against coronavirus disease 2019 (COVID-19) infection. Judo, a close-contact sport, demands careful prevention with great consideration to the risk of infection. The All Japan Judo Federation Medical Science Committee (AJJF) designed COVID-19 prevention protocols from a medical perspective and developed policies for safe regular practices and tournaments.

Foot orthosis treatment improves physical activity but not muscle quantity in patients with concurrent rheumatoid arthritis and sarcopenia.

Objectives: Foot impairment in rheumatoid arthritis (RA) may exacerbate sarcopenia from physical inactivity because of foot pain while walking. The present study aimed to investigate the prevalence of sarcopenia in patients with RA-associated foot impairment, and whether treatment with a foot orthosis improved physical activity and muscle quantity.

Methods: Thirty-two patients with RA were diagnosed as sarcopenic or nonsarcopenic, and the prevalence of sarcopenia was determined.

The objective of this study was to examine the relationship between cartilage degeneration early after partial medial meniscectomy and abnormal alignment in the lower extremity.The subjects were 34 patients (37 knees) with medial meniscal tear who underwent arthroscopic partial meniscectomy. MRI was performed before and 6 months after surgery.

Revascularization to the bone tunnel wall after anterior cruciate ligament reconstruction may relate to the distance from the vessels.

Purpose: We use magnetic resonance angiography to evaluate the difference of vascular ingrowth to the bone tunnel on the anterior and posterior walls quantitatively after anterior cruciate ligament reconstruction.

Materials And Methods: One hundred patients underwent anterior cruciate ligament reconstruction with multi-stranded semitendinosus tendons. They were retrospectively divided into those who underwent magnetic resonance angiography 2, 3, 4 to 6, and ≥ 7 months after surgery.

A nationwide survey on the incidence and characteristics of traumatic spinal cord injury in Japan in 2018.

Study Design: Retrospective epidemiological study.

Objectives: Since the causes and incidences of traumatic spinal cord injury (TSCI) in each country change over time, up-to-date epidemiological studies are required for countermeasures against TSCI. However, no nationwide survey in Japan has been conducted for about 30 years.

Clinical outcomes after medial patellofemoral ligament reconstruction: an analysis of changes in the patellofemoral joint alignment.

Purpose: Medial patellofemoral ligament (MPFL) reconstruction using the hamstring tendon is widely performed to treat recurrent patellar dislocation. MPFL reconstruction includes a post-operative process of necrosis and reperfusion of the hamstring tendon graft. We hypothesise that the patella gradually shifts laterally because of this process, ultimately affecting the patellofemoral joint alignment.

Can a relatively large spinal cord for the dural sac influence severity of paralysis in elderly patients with cervical spinal cord injury caused by minor trauma?

Retrospective reviewThe degree of spinal cord compression and bony spinal canal stenosis are risk factors for the occurrence of spinal cord injury (SCI) without major fracture or dislocation, but they do not affect the severity of neurological symptoms. However, whether a relatively large spinal cord for the dural sac influences the severity of symptoms in SCI cases is unknown.The purpose of this study was to verify the influence of spinal cord size relative to dural sac on the severity of paralysis in elderly patients with cervical SCI caused by minor trauma.

Hepatocyte growth factor regulates HIF-1α-induced nucleus pulposus cell proliferation through MAPK-, PI3K/Akt-, and STAT3-mediated signaling.

Intervertebral discs are important for maintaining mobility and offer support to the body trunk. If these discs lose their biomechanical features, lower back pain can occur. We previously reported that hepatocyte growth factor (HGF) promotes cell proliferation and suppresses apoptosis, inflammation, and matrix degradation in nucleus pulposus (NP) cells.

Reproducibility of radiographic methods for assessing longitudinal tarsal axes Part 2: Severe cavus or flatfoot study.

Introduction: Calcaneal pitch angle and Meary's angle are commonly used to assess longitudinal foot arches on lateral-view radiographs. The aim of this study was to examine and evaluate the radiographic longitudinal foot arch measurement methods with the best intraobserver and interobserver reliabilities for patients with (1) severe cavus deformity and (2) severe flatfoot deformity.

Methods: Standing radiographic images of 22feet with severe cavus foot deformity and 49feet with severe flatfoot deformity were obtained to measure the longitudinal axes of the talus, first metatarsal, calcaneus and plantar surface, which were defined using six, five, four and three different methods, respectively, selected from previous reports.

A modified Terrono classification for Type 1 thumb deformity in rheumatoid arthritis: a cross-sectional analysis.

The most common thumb deformity in rheumatoid arthritis is Nalebuff Type 1 deformity (boutonniere deformity). Type 1 deformity severely impairs hand function, and this impairment is evaluated by the Terrono classification. In some cases, the Terrono classification incorrectly categorizes advanced thumb deformity into earlier stages.
