Spatiotemporal gait characteristics post-total hip arthroplasty and its impact on locomotive syndrome: a before-after comparative study in hip osteoarthritis patients.

Background: Understanding the gait pattern of patients eligible for total hip arthroplasty (THA) due to hip osteoarthritis (OA) offers valuable information for improving locomotive syndrome (LS). This study aims to measure the gait patterns of THA-eligible patients using an optical motion capture system and to analyze these patterns using principal component analysis (PCA). Additionally, this study examines the relationship between THA-induced gait patterns and LS.

Total Knee Arthroplasty Improved Locomotive Syndrome in Knee Osteoarthritis Patients: A Prospective Cohort Study Focused on Total Clinical Decision Limits Stage 3.

Purpose: The purpose of this study is to investigate the treatment efficacy of total knee arthroplasty (TKA) on locomotive syndrome (LS) focusing on total clinical decision limit (CDL) stage 3 leading to revealing the motor function indicators that can predict LS improvement in knee osteoarthritis patients who had received TKA.

Methods: This prospective cohort study was conducted in 47 patients evaluated as total CDL stage 3 before TKA who received primary TKA on the operated side and were diagnosed with Kellgren-Lawrence grade 2, 3, or 4 knee osteoarthritis on the nonoperated side. LS was evaluated using stand-up test, two-step test, and 25-Question Geriatric Locomotive Function Scale.

Shadow pitching deviates ball release position: kinematic analysis in high school baseball pitchers.

Background: Although shadow pitching, commonly called "towel drill," is recommended to improve the throwing motion for the rehabilitation of pitching disorders before the initiation of a throwing program aimed at returning to throwing using a ball, the motion differs from that of normal throwing. Learning improper motion during ball release (BR) may increase shoulder joint forces. Abnormal throwing biomechanics leads to injures.

Effect of total hip arthroplasty on improving locomotive syndrome in hip disease patients: A prospective cohort study focused on total clinical decision limits stage 3.

Background: In 2020, the Japanese Orthopaedic Association established a new stage 3 in clinical decision limits (CDL) to evaluate the stage of locomotive syndrome (LS). This study focused on total CDL stage 3 with the aim of investigating indicators related to improvements in total CDL by evaluating the improvement of LS in patients who underwent total hip arthroplasty (THA).

Methods: Of the 125 patients who underwent THA at our hospital, the subjects of the analysis were 105 patients determined to be total CDL stage 3 in an evaluation performed before THA.

Lifestyle-related signs of locomotive syndrome in the general Japanese population: A cross-sectional study.

Background: This study aimed to estimate the prevalence of locomotive syndrome (LS) risk in age groups using the LS risk test proposed by the Japanese Orthopaedic Association. Based on this, this study identified the lifestyle-related signs that lead to LS, by clarifying the association between LS risk and lifestyle factors.

Methods: A total of 728 individuals aged 20-91 years who were without specific mobility disorders were evaluated.

Relationship between social capital and happiness in a Japanese community: A cross-sectional study.

The influence of social capital on happiness is attracting attention around the world. Many studies that investigated the relationship between social capital and happiness suggest that happiness correlates to a positive social environment. The aim of this study was to examine the relationship between social capital and happiness in a community with the lowest National Health Insurance expenditures in Miyazaki Prefecture (Japan).

Health support program for family members with hospitalized child.

In 2001, we began conducting Health Support Programs on the pediatric ward of Miyazaki Medical College Hospital. The program is designed to help family members who accompany and care for their children who are ill and hospitalized to practice some physical movements for their own benefit. An interview survey was undertaken to clarify the effects and the purpose of the program by evaluating subjective data from program participants, as well as by evaluating changes in participants' blood pressure rates.

[Mental health status and effects on daily life of patients of a large outbreak of Legionnaires Disease].

Objectives: The aim of this study was to survey mental health status among patients of a large outbreak of Legionnaires Disease (LD) occurring at a public bath in Hyuga City, Miyazaki Prefecture, from June through July, 2002. It also aimed to provide a basis for establishing a mental health care support system for persons suffering from ill health.

Methods: Some 295 patients were reported by medical institutions to public health centers as being infected with LD or having suspected infection after using a hot springs bath, where hygiene was assumed to be maintained by regular water circulation, from 6/20 through 7/23, 2002 in Hyuga City, Miyazaki Prefecture.
