Exploring the role of ankle torque fluctuations and intramuscular coherence in gait function among older adults.

Objective: This study aimed to investigate the relationship between ankle joint function and walking performance in older adults by assessing qualitative ankle functions through torque fluctuation analysis and tibialis anterior (TA) intramuscular coherence during isometric dorsiflexion.

Methods: Thirty-eight community-dwelling older adults participated in this study. Ankle torque fluctuations and intramuscular coherence were evaluated during a dorsiflexion task at 30% of maximum voluntary torque (MVT).

Acute effects of resetting the stretching intensity on range of motion and passive stiffness in healthy adults: A randomized crossover trial.

Introduction: Static stretching, a common method used to improve flexibility, has traditionally involved repeated stretching until reaching the initial or pre-determined stretching angle or torque. However, recent recommendations suggest that stretching until reaching a new maximal angle may offer greater benefits owing to increased stretching intensity. This study aimed to examine the acute effects of resetting the static stretching intensity on flexibility.

Working memory load modulates anticipatory postural adjustments during step initiation.

Working memory (WM) can influence selective attention. However, the effect of WM load on postural standing tasks has been poorly understood, even though these tasks require attentional resources. The purpose of this study was to examine whether WM load would impact anticipatory postural adjustments (APAs) during step initiation.

Intermuscular Coherence during Quiet Standing in Sub-Acute Patients after Stroke: An Exploratory Study.

Asymmetrically impaired standing control is a prevalent disability among stroke patients; however, most of the neuromuscular characteristics are unclear. Therefore, the main purpose of this study was to investigate between-limb differences in intermuscular coherence during quiet standing. Consequently, 15 patients who had sub-acute stroke performed a quiet standing task without assistive devices, and electromyography was measured on the bilateral tibialis anterior (TA), soleus (SL), and medial gastrocnemius (MG).

Acute and Prolonged Effects of 300 sec of Static, Dynamic, and Combined Stretching on Flexibility and Muscle Force.

Static stretching (SS), dynamic stretching (DS), and combined stretching (CS; i.e., DS+SS) are commonly performed as warm-up exercises.

EMG-EMG coherence during voluntary control of human standing tasks: a systematic scoping review.

Background: Intra- or inter-muscular (EMG-EMG) coherence is a simple and non-invasive method for estimating central nervous system control during human standing tasks. Although this research area has developed, no systematic literature review has been conducted.

Objectives: We aimed to map the current literature on EMG-EMG coherence during various standing tasks to identify the research gaps and summarize previous studies comparing EMG-EMG coherence between healthy young and elderly adults.

Application of the novel estimation method by shear wave elastography using vibrator to human skeletal muscle.

In recent years, non-invasive measurement of tissue stiffness (hardness) using ultrasound elastography has attracted considerable attention. It has been used to evaluate muscle stiffness in the fields of rehabilitation, sports, and orthopedics. However, ultrasonic diagnostic devices with elastography systems are expensive and clinical use of such devices has been limited.

Acute and chronic effects of static stretching at 100% versus 120% intensity on flexibility.

Purpose: The acute effects of static stretching have been frequently studied, but the chronic effects have not been studied concurrently. Thus, this study aimed to investigate both the acute and chronic effects of static stretching at different intensities on flexibility.

Methods: Twenty-three healthy men were randomly assigned to perform 1 min of static stretching 3 days/week for 4 weeks at 100% intensity (n = 12) or 120% intensity (n = 11).

Changes in Flexibility and Force are not Different after Static Versus Dynamic Stretching.

In this study, we examined the effects of static and dynamic stretching on range of motion (ROM), passive torque (PT) at pain onset, passive stiffness, and isometric muscle force. We conducted a randomized crossover trial in which 16 healthy young men performed a total of 300 s of active static or dynamic stretching of the right knee flexors on two separate days in random order. To assess the effects of stretching, we measured the ROM, PT at pain onset, passive stiffness during passive knee extension, and maximum voluntary isometric knee flexion force using an isokinetic dynamometer immediately before and after stretching.

[Efficacy and safety of weekly taxol (TXL) for advanced recurrent breast cancer evaluated in a multi-center cooperative clinical trial].

A multi-center cooperative clinical trial was undertaken to evaluate the safety and efficacy of weekly taxol (TXL) therapy combined with short-premedication as a pretreatment in an effort to determine if TXL can be used in ambulatory treatment. TXL was administered at 60 mg/m2 to patients with advanced recurrent breast cancer once a week without a rest or with a rest for 1 week after treatment for 3 weeks. A total of 36 patients were finally enrolled.
