Study Notes
Wheelchair and Walking Aids
- Wheelchairs are mobility orthoses providing support for maximum mobility.
- They combine postural support systems and mobility bases, creating a dynamic seated environment.
- Wheelchairs provide protection, stabilize the body, and stimulate activities.
- They allow locomotion for patients with immobilized body parts to perform daily activities (ADLs).
- Wheelchairs enable patients to move without much effort, offering psychological benefits and encouraging engagement with the surroundings.
Common Cases Requiring Wheelchairs
- People who cannot walk or for whom walking is inadvisable.
- Contraindications to weight-bearing.
- Interference with wound healing.
- Inadequate safety in walking.
- Deficiency in the patient's judgment.
- Restrictions against walking can be temporary.
Deficiency in Ambulation
- Involves both lower limbs due to conditions like:
- Absence of an essential part.
- Paralysis.
- Deformity.
- Lack of coordination.
- Wheelchair use may be permanent in these cases.
Wheelchair Prescription Factors
- Age, size, and weight.
- Disability and prognosis.
- Functional skills.
- Indoor/outdoor use.
- Portability/accessibility.
- Reliability/durability.
- Cosmetic features.
- Available options.
- Service.
- Cost.
- Level of acceptance (environment).
Types of Wheelchairs
- Standard wheelchair.
- Standard light-weight wheelchair.
- Ultra-light transport wheelchair.
- Reclining back rigid frame wheelchair.
- Sport wheelchair.
- Heavy-duty pediatric wheelchair.
- Power wheelchair.
Basic Manual Wheelchair Parts
- Push Handle.
- Armrest.
- Push Ring.
- Brake.
- Rear Wheel.
- Anti-tip Bar.
- Castor.
- Backrest.
- Cushion.
- Seat Frame.
- Calf Strap.
- Footplate.
Wheelchair Components
- Wheelchair frame: Stationary or foldable.
- Seat and cushion: Provide high comfort and prevent pressure sores.
- Armrests: Fixed or adjustable, stationary or removable.
- Leg rests: Adjustable or removable.
- Footrests.
- Restraints: Chest belts.
Wheelchair Options and Accessories
- Caster wheels: Vary in size (4-8 inches); smaller size increases maneuverability, larger size increases stability.
- Tire materials: Solid plastic or pneumatic; firmer material increases maneuverability, softer material cushions the ride.
Wheelchair Accessories
- Crutch/cane holder: Small cup at the base with strap for transporting ambulatory aids.
- Anti-tipping device: Placed on the back tipping lever to prevent backward tipping and curb limitations.
- Hill holder device: Mechanical brake allowing forward movement but automatically braking in reverse.
Wheelchair Measurements
- Seat width: Measure the person's seated width plus 1-2 inches (2.5-5 cm) for comfort and bulky clothing.
- Seat back width: Measure the widest part of the person's chest.
- Seat height: Measure from the heel to back of the knee plus 2 inches (5 cm).
- Seat depth: Measure from the back of the hips to the back of the knee plus 1-2 inches (2.5-5 cm).
- Armrest height: Measure from the elbow tip to the hip top with the person in a 90-degree arm position.
- Seat back height: Measure from the hips to the shoulders.
- Headrest height: Measure from the hips to the top of the head.
Importance of Good Measurements
-
Too narrow seat: Uncomfortable, difficult access, pressure sores.
-
Too wide seat: Leaning to one side, promoting scoliosis, difficult propulsion.
-
Too shallow seat: Less contact area, more pressure on soft tissues, less support for feet and legs, poor balance.
-
Too deep seat: Restricted leg circulation, extended leg/forward slide in the chair, difficult propulsion.
-
Lock extensions: Metal tubes to improve rear wheel locking for those with upper limb weakness.
-
Wheel/rim covers: Plastic covers to improve grip for patients with spinal cord injuries or arthritis.
-
Rim projections: Pegs (vertical, oblique, or horizontal) to assist propulsion for patients with poor hand function.
-
Detachable footrests: For stand/pivot transfers.
-
Elevating leg rests: Assist lower extremity circulation, preventing edema and orthostatic hypotension.
-
Removable armrests: Needed for side transfers.
-
Adductor cushion/pommel: Placed between the knees to control adductor spasticity or contractures; seat tilting (10-15 degrees) may aid extensor spasticity or thrusting.
