Wheelchair is an important tool for rehabilitation, it is not only the transport of limb disabled people, more important is that they use a wheel chair for physical exercise and to participate in social activities.Common wheelchair by wheelchair frame, wheels, brakes and seat by four parts.Manual wheelchair based on ordinary wheelchair, increase hand device.
The most important consideration when choosing a wheelchair is the size of the wheelchair.Bear the weight of main parts for people in wheelchairs hips around the ischial tuberosity, around the femur and back around and around the shoulder blades.The size of the wheelchair, especially the seat width, depth and the height of the back of a chair and foot pedal is appropriate, the distance to the seat cushion can make a person related to the blood circulation of the affected, and the skin friction losses, and even pressure ulcers.Also, the safety of patients, operation ability, the weight of the wheelchair, the use of location, appearance and other issues.
Pay attention to the problem folding
: (1) seat width measurement to sit down when the distance between the two hip or two, after add 5 cm or sit down each side have 2. 5 cm gap.Seat is too narrow, the wheelchair is difficult hip and thigh tissue oppressed;Too wide seat is not easy to sit tight, manipulation of the wheelchair is not convenient, double leg fatigue, in and out of the door also have trouble.
2 seat length: measure to sit down when the horizontal distance between the hips and calf, to reduce the measurement result 6. 5 cm.If seat is too short, the weight will fall mainly on the sciatic, easily cause local compression too much;If the oppression popliteal fossa of seat is too long will affect local blood circulation, and easy to stimulate the skin in the department.For shorter legs or patients with hip, knee flexion contracture, will be better to use short seat.
(3) seat height: measuring sit down when the heel (or heel) to the distance of the popliteal fossa, add 4 cm, when placed the pedals, board face at least 5 cm from the ground.Sitting position is too high, the wheelchair can't into the table;The seat is too low, the sciatic bear too much weight.
(4) cushion In order to comfort and prevent bedsore, wheelchair should put cushion on the chair to sit.Common cushion with foam rubber mat (5 ~ 10 cm thick) or gel pad.In order to prevent the subsidence in the cushion seat down a 0.6 cm thick plywood.
The higher the back height: 5] * * back, the more stable, * the lower back, waist and the greater the activity of upper limbs.Low * back: sit face to armpit measurement of distance (an arm or both arms forward horizontally), will this result minus 10 cm.High * back: sit face to the shoulder or measurement after the actual height of the occipital.
 armrest height: sit down, the vertical upper arm, forearm flat on arm, measure the height of chair surface to the edge of the forearm, add 2. 5 cm.Proper armrest height helps to maintain the correct posture and balance, and can make the upper limb is placed in a comfortable position.Armrest is too high, upper arm was forced to elevate, susceptible to fatigue.On the armrest is too low, you need to reach forward to maintain balance, not only easy to fatigue, also can affect the breathing.
Once the wheelchair other auxiliary parts: it is designed to meet the needs of the patients with special, such as increasing the handle of friction surface, car magazines, shockproof device, armrest, installing arm or convenient patients eat, write wheelchair table, etc
