OBJECTIVE To evaluate the effect of body weight-supported progressive high-intensity locomotor training in Parkinson's disease (PD) on (1) clinical status; (2) quality of life; and (3) gait capacity. DESIGN Open-label, fixed sequence crossover study. SETTING University motor control laboratory. PARTICIPANTS Patients (N=13) with idiopathic PD (Hoehn(More)
It was the primary objective of this study to investigate whether quantifying fluctuations in dorsi and plantarflexor torque during submaximal isometric contractions is a reliable measurement in young healthy subjects. A secondary objective was to investigate the reliability of the associated muscle activity (EMG) data. Eighteen young subjects (12.8 ± 3.1(More)
The aim of this study was to (1) examine the test-retest reliability of approximate entropy (ApEn) calculated for torque time-series from attempted steady isometric contractions performed at two different days, and (2) examine the significance of the sampling frequency for the ApEn values. Eighteen healthy young subjects (13+/-3 years, mean+/-1 S.D.)(More)
OBJECTIVES ICU admission is associated with decreased physical function for years after discharge. The underlying mechanisms responsible for this muscle function impairment are undescribed. The aim of this study was to describe the biomechanical properties of the quadriceps muscle in ICU survivors 12 months after ICU discharge. DESIGN Case-control study(More)
The aims of this study were to: (1) investigate the significance of muscle activation variability and coactivation for the ability to perform steady submaximal ankle torque (torque steadiness) in healthy children and those with cerebral palsy (CP), and (2) assess ankle function during isometric contractions in those children. Fourteen children with CP who(More)
We investigated lower-extremity isometric tremor Approximate Entropy (irregularity), torque steadiness and rate of force development (RFD) and their associations to muscle activation strategy during isometric knee extensions in patients with Parkinson's disease (PD). Thirteen male patients with idiopathic PD and 15 neurologically healthy matched controls(More)
The aim of this study was to investigate the effect of high-intensity locomotor training on knee extensor and flexor muscle activation and adaptability to increased body-weight (BW) support during walking in patients with Parkinson's disease (PD). Thirteen male patients with idiopathic PD and eight healthy participants were included. The PD patients(More)
INTRODUCTION Approximate entropy (ApEn) [1] calculated from isometric tremor torque time-series provides additional information of the neuromuscular system, compared to that obtained from the traditional analysis (standard deviation (SD) or spectral analysis) [2]. The ApEn value is determined by the complex pattern of the neuromuscular system, decreases(More)
BACKGROUND Critical illness is associated with muscle weakness leading to long-term functional limitations. OBJECTIVES To assess the reliability of a novel method for evaluating fatigability of the quadriceps muscle in noncooperating healthy subjects. METHODS On two occasions, separated by seven days, nonvoluntary isometric contractions (twitch and(More)
