This study examined the difference in falls between older adults who participated group exercise and those exercised alone. We used cross-sectional data from Japan Gerontological Evaluation Study. Data were obtained functionally independent residents aged 65 years or across 30 municipalities (n = 19,257). Logistic regression analysis was performed with experience of multiple over past year as dependent variable type variable. Respondents divided into three groups according to how they...

Abstract Background After total knee arthroplasty (TKA), patients’ physical activity (PA) levels at 6 months are lower than those of healthy subjects. Few studies have investigated the factors associated with PA after TKA by objectively measuring preoperative and postoperative intensity using an accelerometer function a goniometer dynamometer. The purpose this study was to determine based on objective data. Methods Eighty-two patients (mean [SD] age 74.5 [6.4] years) moderate-to-severe...

The early-stage of knee osteoarthritis (OA) is usually asymptomatic. However, timely detection can prevent further cartilage degeneration via appropriate exercise prescription and behavioral change. In this article, a noninvasive method to diagnose the OA recording vibroarthrographic (VAG) signals over mid-patella during standing movement proposed. A that combines empirical mode decomposition (EMD) wavelet transform developed analyze nonstationary VAG signals. least squares support vector...

This cross-sectional study aimed to determine the predictors of a walking speed <1 m/s. Factors associated with health muscle cells, including phase angle analyzed using bioimpedance analysis, answers mini-nutritional assessment-short form, albumin levels, leg quality and vitamin D were assessed.The participants outpatients from Locomotor Frailty Outpatient Clinic which was established at our center in 2016 (231 women, 76.5 ± 7.6 years; 137 men, 78.0 6.3 years). Participants classified into...

Study Design Case control study. Objective To compare the patellar mobility of female adult subjects with and without patellofemoral pain (PFP). Background Although abnormal is believed to be one causes PFP, there currently no published evidence support this contention. In part, lack because a reliable clinical measurement method measure objective criteria define have not been established. Methods Measures The study sample was comprised 22 females PFP (PFP group) who had knee (control...

Study Design Repeated-measures, within-subject design. Objectives To assess the concurrent criterion-related validity and reliability of a clinical device to quantify lateral patellar displacement. Background Excessive displacement patella is an impairment that widely associated with patellofemoral pain and/or pathology. Currently, no valid or reliable method has been described in literature. Methods Measures A total 26 individuals (14 asymptomatic 12 symptomatic; mean ± SD age, 27 4 years)...

BACKGROUND: Posture and physical function have been quantified in mature adults, but not elderly females. OBJECTIVE: To quantify standing posture measures of community-dwelling women over the age 65 years, to examin

[Purpose] The purpose of this study was to elucidate the relationship between knee muscle strength and pain in activities daily living, based on consideration difference extension flexion (Q - H) hamstring:quadriceps (H:Q) ratio patients with osteoarthritis. [Subjects Methods] participants were 78 females osteoarthritis, a total 133 knees that had not been treated surgically targets research. legs divided according dominance. Isometric during living measured. H:Q (flexion/extension strength)...

This study describes a new calibration procedure that provides simple and accurate method to place align an inertial measurement unit (IMU) sensor with the relative clinical bone frame on developed lower limb skeletal model. The can be easily replicated without need for additional tools and, more importantly, it is independent of joint attachment position. proposed was validated under realistic gait tests using eight healthy subjects in motion capture system environment. Calculated results...

The purpose of this study is to organize issue-oriented interdisciplinary curricula, in which natural language processing, and machine learning-based automatic classification are combined. recent explosion scientific knowledge due the rapid advancement academia society makes it difficult for learners educators recognize overall picture syllabus. In addition, growing amount research harder find subjects that suit their needs from syllabi. an attempt present clear directions suitable subjects,...

[Purpose] The purpose of this study was to investigate the influence a decrease in thoracic kyphosis angle on knee adduction moment during gait healthy young individuals. [Subjects and Methods] Twenty-nine adults, consisting 15 males 14 females (21.6 ± 1.1 years old), participated. draw-in maneuver used kyphosis, measured using SpinalMouse normal standing with maneuver. participants were required maintain gait. A 3-D motion analysis system force plate obtain moment. [Results] Thoracic angles...

[Purpose] The aims of the present study were to investigate most suitable location for vibroarthrography measurements knee joint distinguish a healthy from osteoarthritis using Wavelet transform analysis.

Patellofemoral cartilage degeneration is a potential complication of anterior cruciate ligament reconstruction (ACLR) surgery. Hypomobility the patella in coronal plane often observed after ACLR. Few studies, however, have examined relationship between patellofemoral joint and mobility The present study investigated 1) ACLR, 2) patellar joint, 3) knee function Forty patients who underwent medial hamstring-based ACLR participated study. Lateral displacements were assessed with modified...

Finite element musculoskeletal (FEMS) approaches using concurrent (MS) and finite (FE) models driven by motion data such as marker-based trajectory can provide insight into the interactions between knee joint secondary kinematics, contact mechanics, muscle forces in subject-specific biomechanical investigations. However, these data-driven FEMS systems have two major disadvantages that make them challenging to apply clinical environments: they are computationally expensive require...
