Urinary incontinence (UI) is a major social problem for older adults and leads to decline in health-related quality of life (HRQoL), mental health, physical activity. This study assessed the prevalence symptoms UI among discharged from hospital Japan investigated association with activity, HRQoL, subjective well-being (SWB). By an international consultation, Incontinence Questionnaire Short Form (ICIQ-SF) that assesses severity, was developed. Self-administered questionnaires were used...
The plantar fascia and intrinsic foot muscles (IFM) modulate stiffness. However, it is unclear whether the corresponding ultrasonography findings reflect it. This study aimed to examine effect of IFM morphologies on force attenuation during landing reactivity when jumping in healthy adults (n = 21; age, 21–27 years). Thickness, cross-sectional area (CSA), hardness fascia, abductor hallucis (AbH), flexor brevis (FHB) were measured using ultrasonography. Single-leg drop repetitive rebound...
Background: Foot malalignment can augment the risk of lower-extremity injuries and lead to musculoskeletal disorders. This study aimed clarify contribution rearfoot alignment plantar pressure distribution spatiotemporal parameters during gait in healthy adolescent athletes. Methods: retrospective included 39 athletes who were divided into eversion control groups according a leg heel angle 7°. A total 78 legs analyzed (45 33 [women, 53.3%] 48.5%], respectively). Gait was assessed using an...
Abstract Purpose To quantify the vertical translation between first metatarsal and medial cuneiform during stance phase of gait in young individuals with without hallux valgus. Design This cross-sectional observational study included 34 adults (male, n = 4; female, 30) who were divided into three groups according to valgus angle: control (< 20°, 13), mild (≥ 20° < 30°, 12), moderate 9). The mobility tarsometatarsal joint was evaluated using B-mode ultrasound synchronized a motion...
We determined how the in vivo mobility of first tarsometatarsal (TMT) joint can be quantified during gait. Twenty-five healthy participants (12 females) with no history foot disorders were included. Non-invasive ultrasound (US) a three-dimensional motion analysis (MA) system was used to evaluate kinematic characteristics TMT stance phase US probe positioned longitudinally above and adjusted its proximal dorsal prominence. Gait conducted by MA starting activation B-mode video at 80 frames per...
[Purpose] Muscle quantity (e.g., cross-sectional area) and quality muscle adipose tissue), which are strength determinants, can be assessed using ultrasonography. The study aimed to investigate the changes in of peroneus longus evaluate evertor legs with chronic ankle instability (CAI). Furthermore, associations among area, echogenicity, strength, frequency sprain were examined. [Participants Methods] Nine males CAI unilateral voluntary participants this study. area longus, measured for all...
BACKGROUND: Local vibration (LV) used as part of the warm-up can stimulate a specific body and muscle group, potentially increasing flexibility performance. However, effect its combination with static stretching (SS) has not been thoroughly examined. OBJECTIVE: To elucidate acute effectiveness combining LV SS (V+S) on ROM ankle dorsiflexion, squat jump, counter-movement jump (CMJ) dynamic postural stability index (DPSI). METHODS: Fifteen healthy men who were regularly involved in...
This study aimed to evaluate motor unit recruitment during submaximal voluntary ramp contraction in the medial head of gastrocnemius muscle (MG) by high-density spatial electromyography (SEMG) before and after static stretching (SS) healthy young adults. SS for was performed 15 participants 2 min. Normalized peak torque bodyweight plantar flexor, activity at torque, activation patterns ramp-up task were evaluated SS. Motor MG measured using SEMG when performing contractions isometric ankle...
In classical ballet, dancers may wear flat shoes and pointe shoes. To consider the kinematic changes between to prevent injuries, it is essential focus on fundamental ballet movement of standing pointe. This study aimed clarify differences in center pressure (COP) displacement lower limb muscle activity during descending phase a relevé when wearing versus shoes.Ten amateur volunteered for this performed reléve We measured COP by using footplate electromyographies tibialis anterior, soleus,...
This cross-sectional study aimed to investigate the relationship between foot shape and intrinsic muscles (IFMs) in adolescent swimmers compared with other athletes. Foot morphology of was athletes comparable age a competition level (n = 32 [64 feet]; total 64 feet; 128 feet two groups). variables IFMs were measured using three-dimensional scanner an ultrasound imaging system, respectively. Multiple linear regression analysis forced entry performed clarify association thickness area (CSA)...
We present the magnetic resonance (MR) images of exogenous hemochromatosis in thyroid gland. On both T1-weighted and T2-weighted showed low intensity similar to that back-ground. Magnetic is value imaging tissue deposition iron. In assessing iron accumulation, MR superior CT because can not differentiate from normal iodine concentration.
Virtual reality (VR)-based rehabilitation has been used in lower limb amputees; however, the extent to which VR is effective reacquiring symmetrical gait amputees unclear. The purpose of this study was confirm whether a intervention obtaining simulated prosthetic gait. participants were 24 healthy males who had never worn prosthesis. They divided into three groups: VR, tablet, and control groups. consisted 5 min situ stepping on parallel bars watching video leg walker head-mounted display or...
Background and Objectives: Double poling is an important fundamental skill required for cross-country skiing in able-bodied athletes those with physical disabilities. Meanwhile, the performance improvement injury prevention related to double requires a thorough assessment, whereas scapular shoulder kinematics different postural conditions remain be clarified. The main purpose of this study was evaluate biomechanics during ski standing sitting positions. Materials Methods: Eleven participants...
Functional predictors of home discharge after hip fractures have been widely reported; however, no study has considered the geographical features surrounding patients' homes. This aimed to identify and determine cutoff points required for patients living in sloped neighborhoods or islands. A total 437 postoperative fracture were included classified into flat, slope, island groups according their residential area before fracture. Multivariate logistic regression analysis was used significant...
Novel coronavirus disease (COVID-19) spread worldwide. In Japan, From April 16 to May 25, 2020, a state of emergency was declared and people were "strongly requested refrain from going out unnecessarily thoroughly reduce contact with others." As result, the number steps all generations expected be lower than usual due novel pandemic. This study investigated weather walking decrease in collegiate student COVID-19. A total 221 students used their smartphones enter average taken every month...
Abstract Background : Ankle orthotics decreases the maximal vertical jump height. It is essential to maximize height and minimize ground contact time during athletic performance. However, effect of ankle on performance has not been reported. We aimed investigate squat (SJ), countermovement (CMJ), repetitive rebound (RJ) relationship between restriction in sagittal range motion. Methods Twenty healthy volunteers performed SJ, CMJ, RJ under no-orthosis two orthotic conditions (orthosis 1...
<h3>Background</h3> Niseko, which is located north of Japan, becomes a famous ski resort for the best powder snow called as 'JAPOW' or 'NISEPOW'.
