Abstract Objective To investigate whether the impacts of height increase on gastrocnemius muscle (GM) stiffness are greater in children with spastic cerebral palsy (CP) than those typical development (TD). Design This one-year cohort study enrolled (CP, 23; TD, 23) who underwent two measurements conducted at entry and after one year. Lateral medial GM-strain ratios representing were obtained using elastography. Results All regression equations (dependent variable, rate change [RoC] height;...
Developing Age-Friendly Cities and Communities (AFCCs) is an increasingly popular policy response to supporting ageing populations. AFCC programmes rely on cross-sectoral collaboration, involving partnerships among diverse stakeholders working across sectors address shared goals. However, there remains a limited understanding of what mechanisms strategies drive collaboration actors within age-friendly cities. To this gap, empirical paper draws examples from comparative case study Akita...
Aim To clarify the age‐related changes in muscle elasticity or thickness of lower extremities older women, and to analyze their relationship with physical functions. Methods The rectus femoris medial head gastrocnemius 102 young women (young group) 221 elderly (elderly were measured using ultrasonography. In group, functions, including knee extension strength, Timed Up Go test, single‐leg standing, maximum gait speed Four Square Step Test also measured. Results significantly higher, but both...

The Kellgren Lawrence grading scale was used for radiographic evaluation OA. EI measured as grayscale values. change ratio anteroposterior length during quadriceps contraction measured. Knee range motion pain (100-mm visual analog scale) evaluated.The significantly...
〔目的〕本研究の目的は脳性麻痺児（以下，CP児）を対象として，歩行時の効率を示す指標であるPhysiological Cost Index（以下，PCI）とTotal Heart Beat Index（以下，THBI）の再現性を検討することである。〔対象〕対象は実用歩行が可能な痙性両側麻痺型脳性麻痺児8名とした。年齢の平均値±標準偏差は11.3±3.5歳（範囲：6歳7ヶ月～17歳11ヶ月）であった。〔方法〕第1日目に安静時脈拍数と，10分間の歩行中の脈拍数と歩行距離を測定し, 得られたパラメーターをそれぞれ平均した。測定を第1日目に2回行い，3～7週間後（以下，第2日目）さらに1回測定した。第1日目と第2日目のPCIとTHBIから，級内相関係数（intraclass correlation coefficient；以下，ICC）並びにsmallest detectable...
Background: Developing a home-based training (HBT) program can increase gait performance in children with cerebral palsy (CP) who receive insufficient clinical or institutional-based therapy.Objective: To investigate the effect of HBT focusing on increasing maximum step length (MSL) walking function spastic diplegic CP.Methods: Although this was randomized controlled trial, subjects had known own allocation. determine change as effect, MSL variables and at end (second assessment, 8 weeks)...
Aims: The objective of this study was to introduce mobile telerehabilitation with tablet computers and verify its practical effectiveness in improving physical function health status. Methods: In study, nine adults aged 76.3 ± 3.3 years old participated 13 exercise sessions led by a therapist each lasting 60 min every 2 weeks for total 6 months. A performed exercises front digital camera which connected lab computer. community center, participants the while watching performance on screen....
This study aimed to investigate the echo intensity (EI) of pretalar fat pad (PFP) in young individuals with chronic ankle instability (CAI) and clarify relationship between changes PFP clinical characteristics CAI. Using Identification Functional Ankle Instability (IdFAI) scores, 26 limbs 15 participants were divided into CAI (IdFAI score ≥11, male: eight limbs, female: six age: 21±1 years) normal <11, nine three 20±1 groups. The EI was measured, luminosity ratio (LR) subcutaneous adipose...
[Purpose] In children with cerebral palsy, despite increases in muscle strength after strengthening, improvements walking efficiency are inconsistent previous studies. The purpose of this study was to analyze the relationship between and palsy. [Participants Methods] Twenty-six palsy participated study. Isometric lower extremities Total Heart Beat Index were measured. Participants divided into high low groups based on median value (2.06 beats/m). [Results] For all participants, isometric...
〔目的〕歩行中の加速度データから身体重心の変位を算出し，その妥当性を検討することを目的とした．〔対象と方法〕健常男子学生11名を対象とし，加速度計を第3腰椎レベルに装着して3次元動作解析装置の測定域で8条件の歩行を行った．上下・左右方向の加速度データから重心変位を算出し，3次元動作解析装置から算出した重心変位と比較した．妥当性の検討には級内相関係数（ICC）とBland-Altman分析を用いた．〔結果〕いずれの歩行条件においても加速度から算出した重心変位は上下方向で強い相関（0.73-0.94）を示し，左右方向は中等度以下の相関（0.31-0.71）を示した．また，多くの条件下で加算誤差と比例誤差が認められ，加速度計の重心変位が大きかった．〔結語〕加速度データから重心変位を算出することは，歩行の変化を視覚的・直感的に把握できる点において有用であり，簡便に用いられる歩行分析ツールとなり得ることが示唆された．
Abstract We aimed to elucidate the relationship between active force production and curvature of central aponeurosis (CA) rectus femoris in young healthy participants as fundamental data compare muscle CA before after straight leg raising (SLR) training with knee osteoarthritis (OA). Central was determined during submaximal maximal voluntary contractions (MVCs) using ultrasonography. Twenty-five female volunteers underwent ultrasonographic measurements under conditions isometric MVC. They...
〔目的〕短時間の静的ストレッチング（以下，SS）が大腿直筋の柔軟性と筋力に及ぼす効果について検討すること．〔対象と方法〕運動習慣が週2日以内の健常若年者30名の右下肢を対象とした．伸張時間を2，4，6，8，10，30秒でSSを行い，それぞれの前後で，踵殿距離，大腿直筋のエラストグラフィによる歪み比と等尺性膝伸展筋力を算出した．〔結果〕踵殿距離は2秒～30秒すべてのSS後に，大腿直筋の歪み比は8秒以上のSS後に有意な低下が見られた．筋力は8秒間まではSS後の変化がなく，10秒以上で有意な低下が見られた．〔結語〕8秒間のSSでは，大腿直筋の筋力が維持され，柔軟性が向上するのに対し，10秒以降では柔軟性が向上し，筋力は低下することが示唆された．
〔目的〕頭頸部伸展位が片脚着地動作に及ぼす影響を明らかにすること．〔対象と方法〕対象は，健常成人女性31名（平均20.1歳）とした．高さ30 cm台からの片脚着地動作を，頭頸部屈曲伸展中間位と，頭頸部伸展位の2条件で行った．片脚着地時の最大の膝関節屈曲と外反角度，体幹前後屈，側屈角度，および着地位置を測定し，条件間で比較した．〔結果〕頭頸部伸展位での着地では頭頸部屈曲伸展中間位の着地に比べて最大膝関節外反角度が有意に大きかった．最大膝屈曲角度と体幹前後屈，側屈角度，着地位置には有意差はみられなかった．〔結語〕頭頸部伸展位での片脚着地動作は膝関節外反角度を増大させ，非接触型前十字靭帯損傷の一要因となると推察された．
