Abstract Background and Purpose Anthropometric data is an essential part of the ergonomics design of the equipment, environment and work. Using anthropometric information, designers will be able to design appropriately the needs of the dimensional characteristics of the target group. According to studies, the structural characteristics of the human body are influenced by factors such as ra...
The pattern of propulsion was investigated for five male paraplegics in six seating positions. The positions consisted of a combination of three horizontal rear-wheel positions at two seating heights on a single-purpose-built racing wheelchair. To simulate wheelchair propulsion in the laboratory, the wheelchair was mounted on high rotational inertia rollers. For three trials at each seating pos...

Importance of the functional examination in lower extremities in patients with rheumatoid arthritis.
This paper deals with evaluation of the lower extremity efficiency and balance in rheumatoid arthritis (RA) patients. The authors' own test (LLFT-lower extremities functional test) and balance tests during normal standing and tandem positions with eyes opened or closed were used.
