OBJECTIVE To compare the energy expenditure in patients with unilateral knee osteoarthritis while walking with canes of different lengths. METHODS A quasi-experimental study (single-group) was carried out on thirty patients with unilateral knee osteoarthritis. An adjustable aluminum cane was used, and three different cane lengths were determined for each subject: C1--length from the floor to ...
background: work clothing can limit heat exchange between humans and the environment and cause thermal strain and heat-related disorders in workers. it can thus reduce both efficiency and productivity. the purpose of this study was to examine the effects of work clothing material on physiological strain index (psi) in climatic chamber. methods: an interventional study was conducted on 18 male s...
Electroencephalography (EEG) is an important physiological index of cognitive workload. While previous research has employed high-end EEG devices, this work investigates the feasibility of measuring cognitive workload with a low-cost EEG system. In our experiment, EEG signals are recorded from subjects performing silent reading tasks under different difficulty levels. Experimental results demon...
Introduction: Heat stress is one of the hazardous agents in the steel industries which can threaten the health and safety of workers and lead to serious occupational diseases. The aim of the study was to assess the heat stress in the steel industries and compare PHS (Physiological Strain Index), WBGT (Wet-Bulb Globe Temperature), DI (Discomfort Index) and HSI (Heat Stress Index) indices for the...
OBJECTIVE To examine, for polio survivors, whether walking with a carbon-fibre reinforced plastic knee-ankle-foot orthosis (carbon KAFO) is more efficient than walking with an ordinary KAFO or without an orthosis. DESIGN Consecutive sample. SETTING Post-polio clinic, University Hospital of Occupational and Environmental Health, Kitakyushu, Fukuoka, Japan. PARTICIPANTS Eleven polio survivo...
