Evaluation of the Anatomical Cross-Sectional Area of Psoas Major Muscle Using an Ultrasound Imaging System Combined With an Inertial Measurement Unit: Improved Reliability in the US Using IMU-Based Positioning Techniques.

Recently, ultrasound (US) imaging has been used to estimate the cross-sectional area of skeletal muscle, but the reliability is uncertain. To improve the reliability of the US, we investigated skeletal muscle thickness measurement using an inertial measurement unit (IMU) to determine the direction of US beam incidence based on posture angle information. In addition, we examined whether the anatomical cross-sectional area (ACSA) of muscle can be estimated from the muscle thickness measured using the US with the IMU.

Effect of Different Ankle-Foot Immobility on Lateral Gait Stability in the Stance Phase.

Background: This study aimed to investigate the effect of limited foot and ankle mobility on the lateral stability of gait through the observation of the mediolateral margin of stability and related kinematic parameters.

Methods: Thirty young, healthy participants walked at a fixed gait velocity on a level surface. Participants achieved different degrees of restricted mobility by wearing soft-soled shoes (S), an ankle-foot orthosis with unrestricted dorsiflexion-plantarflexion activity only (A), and an ankle-foot orthosis with unrestricted dorsiflexion-plantarflexion and adjustable horizontal rotation of the foot (OU/OR).

Comparison of clinical outcomes following early rehabilitation in 3 cases of nephrotic syndrome with different treatment courses.

There have been few published reports regarding rehabilitation for nephrotic syndrome. We compared the clinical outcomes of three cases of nephrotic syndrome with different treatment courses during 5 weeks of early rehabilitation.We report on three cases of nephrotic syndrome.

The influence of trunk muscle strength on walking velocity in elderly people with sarcopenia.

[Purpose] Sarcopenia increases the risk of falls and fractures. However, its relationship with walking, which is the generation mechanism of falls, has not been clarified. The purpose of this study was to clarify the trunk muscle strength and the characteristics of walking, in elderly people with sarcopenia.

A pilot study to relationship between urinary protein excretion and muscle strengthening in patients with acute onset renal disease.

Purpose: The purpose of this study was to investigate urine protein excretion and the effect of muscle strengthening in patients with renal disease.

Subjects: Twenty-eight patients (18 to 87 years old) with acute onset renal disease were treated with steroids at the Hospital of Shiga University of Medical Science. Maximum quadriceps force was measured, and 20-minutes sessions in resistance training were started.

Evaluation of the safety, effectiveness, and health-related QOL impact of early rehabilitation in patients with nephrotic syndrome.

Background: The aim of this study was to evaluate the safety, effectiveness, and health-related QOL impact of early rehabilitation in patients with nephrotic syndrome.

Methods: Subjects consisted of 23 patients with nephrotic syndrome who had previously received steroid treatment. Patients worked performed quadriceps resistance training and aerobic training 5 days per week for 5 weeks.

Forefoot flexibility and medial tibial stress syndrome.

Purpose: To investigate the association between medial tibial stress syndrome (MTSS) and morphology and flexibility of the foot arches.

Methods: 131 feet from 74 healthy subjects and 31 feet from 27 patients with MTSS were classified as normal feet (n=78 in 40 subjects), flat feet (n=53 in 34 subjects), or MTSS feet (n=31 in 27 patients). The medial longitudinal arch (MLA) ratio and the transverse arch length (TAL) were measured in both rearfoot and forefoot loading positions.

Estimations of One Repetition Maximum and Isometric Peak Torque in Knee Extension Based on the Relationship Between Force and Velocity.

We aimed to investigate whether a linear regression formula based on the relationship between joint torque and angular velocity measured using a high-speed video camera and image measurement software is effective for estimating 1 repetition maximum (1RM) and isometric peak torque in knee extension. Subjects comprised 20 healthy men (mean ± SD; age, 27.4 ± 4.

Flexibility of the transverse arch of the forefoot.

Purpose: To measure the percentage of the transverse arch length (%TAL) in 2 positions using a 3-dimensional motion capture system to determine the flexibility of the transverse arch of the forefoot.

Methods: 19 men and 10 women with no lower extremity injury or deformity were included. The %TAL of the left foot was measured using a digital caliper in the standing position and the lower leg maximum anterior tilting (LMAT) position.

Effect of low-repetition jump training on bone mineral density in young women.

The hypothesis of the present study was that low-repetition and high-impact training of 10 maximum vertical jumps/day, 3 times/wk would be effective for improving bone mineral density (BMD) in ordinary young women. Thirty-six female college students, with mean age, height, and weight of 20.7+/-0.
