A sports wheelchair is a very important necessity for athletes with disabilities. Therefore, there are many factors to consider when choosing a sports wheelchair. Next, let's take a look at the considerations related to the purchase of a sports wheelchair. Here are some answers.
Here is the list of contents.
Choice of seat size.
Choice of the seat cushion and seat back.
Choice of seat size.
The width of a sports wheelchair seat is based on the distance between the two hips or between the two femurs when sitting down, plus 5 cm, or 2.5 cm of clearance on each side when sitting down. If the seat of a sports wheelchair is too narrow, it will be more difficult to get in and out of the wheelchair, and the hip and thigh tissues will be compressed. If the seat is too wide, it is not easy to sit firmly, it is not convenient to operate the wheelchair, and the limbs are easily fatigued. The length of the seat is based on the horizontal distance between the rear hip and the calf gastrocnemius muscle when sitting, and the measurement is subtracted by 6.5 cm. If the seat of the sports wheelchair is too short, the weight will fall mainly on the isthmus, which will easily cause excessive pressure on that area. If the seat is too long, it will compress the popliteal fossa, affecting local blood circulation and tending to irritate the skin in that area. For patients with short thighs or with hip and knee flexion contractures, a short seat is recommended. For the height of the seat, measure the distance from the heel to the popliteal fossa while sitting and add 4 cm. If the seat is too high, the wheelchair cannot be placed next to a table; if the seat is too low, the seat bones will bear too much weight.
Choice of the seat cushion and seat back.
For comfort and to prevent bed sores, a seat cushion should be placed on the chair of a sports wheelchair. Common seat cushions are foam rubber cushions or gel cushions. To prevent the seat from sinking, a 0.6 cm thick plywood can be placed under the seat cushion. The seat back height of a sports wheelchair is measured as follows. The high seat back measures the actual height from the sitting surface to the shoulder or back pillow, while the low seat back measures the distance from the sitting surface to the armpit and subtracts 10 cm from this result. The higher the seat back of an exercise wheelchair, the more stable the exercise wheelchair will be. The lower the seat back, the more movement there is in the upper body and upper limbs.
