Q

Good indicators that your patient would benefit from wheeled mobility

A
  • Patient is non-ambulatory
  • Demos decreased safety with ambulation or is at risk for falls within the home
  • Requires assistance for ambulation within the home & wheeled mobility would allow independence
  • Requires increased time for ambulation within the home
  • Unable to consistently ambulate throughout the day in the home which affects their ADLs

Q

Questions to help justify your patient’s need for a wheelcahir

  • Can the mobility limitation be resolved by a cane or walker?
  • Do they have the desire or capability to propel o WC?
  • Does the pt’s home have the space/layout for functional WC use?

Q

Describe wheelchairs for long-tern use

A
  • K level 4: Pt qualifies for a basic manual chair but requires a seat width, depth, or height that can’t be accommodated by a basic MWC; unable to perform all ADLs efficiently in a basic MWC; they use a WC more than 2 hrs/day
  • K level 5: Pt is a full time WC user, Pt requires customization such as axle configuration wheel camber angle or seat to back angle that can’t be accommodated by a K level 1-4; requires an evaluation by a pt/OT, a letter of medical necessity, & the involvement of an ATP in the equipment selection process

Q

When is a tilt in space appropriate

A
  • Pt is dependent in mobility
  • Pt is unable to perform independent pressure relief
  • Pt requires gravity assisted positioning/repositioning
  • Pt requires postural support, head & trunk control, and accommodation of postural asymmetries
  • Goal is to increase sitting tolerance/endurance
  • Pt needs improved line of sight due to forward head posture
  • Pt will benefit from trunk support & open thoracic posture for increased respiratory function
  • Pt requires safe positioning for feeding/gravity assisted swallowing

  • The pt is unable to safely transfer, operate, & maintain postural stability in scooter
  • The home does not provide adequate access for operating scooter
  • Pt is able to safely operate a power WC or has a caregiver willing to operate who cannot push a manual WC
  • Will improve the ability to participate in MRADLs in the home
  • Some models have multi power options available if they qualify for a tilt/recline system or if they use a ventilator that mounts to the chair

Q

What makes a group 3 power WC different from a group 2 power WC

A
  • Allows integration of rehab seating, & typically has better drive wheel suspension
  • Offer multiple alternative drive control options
  • Offer the option of power tilt, recline, and/or power legs, & power elevate
  • Higher turning radius & increased speeds

Q

What is each body part doing during neutral pelvic posture and what is the goal

A
  • Goal: maintain proper alignment with an appropriate cushion & back support
  • Pelvis is in midline with no pelvic tilt, no obliquity, & no rotation
  • Spine is balanced & upright with no rotation and no lateral curvature
  • Head is functionally upright with only mild forward/lateral flexion or rotation

Q

Describe a fixed deformity

A
  • Fixed = accommodate
  • When a posture is fixed the skeleton does not move out of the posture
  • Pt needs equipment that will accommodate the fixed posture providing optimal support & pressure redistribution
  • Goal = preventing further progression
17
Q

Describe a flexible deformity

A
  • Flexible = correct
  • When a posture is flexible the skeleton still moves & equipment should be chosen with the goal to correct the abnormal posture
  • Goal = prevention from becoming a fixed posture
18
Q

What is each body part doing during anterior pelvic tilt and what is the goal

A
  • Goal: utilize cushion & back support that maximizes contact with seat surface, stability, & look for moldable back support to conform to the curvature of the spine
  • Pelvis sits with PSIS higher than the ASIS
  • Spine has excessive lordosis in the lumbar and cervical spine
  • Head has excessive lordosis of cervical spine causing hyperextension of the neck & upward eye gaze
19
Q

What is each body part doing during pelvic obliquity and what is the goal

A
  • Goal: pressure redistribution, flexible = level the pelvis by building up lower side, & fixed = accommodate for the deformity
  • Pelvis sits with L/R ASIS higher than the other
  • Thoracic spine curves away from the side of the raised hip
  • Neck laterally flexes into the side where the hip is higher
20
Q

What is each body part doing during pelvic rotation and what is the goal

A
  • Goal: stabilize pelvis in most neutral position and consider an anti-thrust cushion to reduce forward migration of the pelvis
  • Pelvis sits with L/R ASIS more forward than the other
  • Thoracic spine follows & rotates in the same direction as the pelvis
  • Neck will go into lateral flexion as if the person is dropping the ear to his or her shoulder
21
Q

What is each body part doing during windswept posture and what is the goal

A
  • Goal: avoid use of ELRs that decrease femoral contact with seat surface & promote windswept posture, often accompanied by rotation or obliquity of the pelvis, & look for a cushion that can be adjusted
  • Pelvis goes hand in hand with a rotation of an obliquity causing one leg to adduct and the other leg to abduct
  • Spine will present with a rotation or scoliosis
  • Neck will go into lateral flexion & may be accompanied by forward flexion
22
Q

What are the top 8 measurements you MUST do for wheelchair fitting

A
  • Shoulder width
  • Chest width
  • Hip width
  • Seat to top of shoulder
  • Inferior angle of scapula
  • Seat to elbow
  • Upper leg length
  • Lower leg length
23
Q

What happens to the skin, tissue, & bone when constant pressure is applied without the appropriate pressure redistribution in the cushion & back support

A
  • Initially it affects only the superficial epidermal layer causing a reddening of the skin (skin is still intact)
  • Eventually the pressure moves into the dermis breaking the skin open & causing an open wound (blisters may appear)
  • Continued pressure damages deeper into the hypodermic now affecting all 3 layers of skin
  • Injury depth reaches the tissue under the skin potentially as low as the muscle & bone
24
Q

What are the mechanics of sheer force

A
  • Gravity causes downward pressure from prolonged sitting
  • Pt moves/slides in the chair causing friction
  • Skin/tissue at the seat surface DOESN’T move while the underlying bone structure DOES
  • Skin/tissue is strained by the combined pressure & friction
  • Permanent cell deformation & distortion occurs at the deeper layers of tissue
  • Blood vessel damage decreases oxygen delivery
  • Ischemia
  • Result is tissue death
25
Q

Define offloading

A
  • Principle of taking pressure off of a small surface area & loading it onto a greater surface area that can withstand more pressure & prevent unwanted skin breakdown
26
Q

Define immersion

A
  • Principle of conforming to the person’s curvature by “sinking the body in”
  • We allow the cushion and/or back support to take the body’s shape alleviating the bony prominences from unwanted peak pressure to maximize pressure redistribution
27
Q

Benefits of using an offloading style cushion

A
  • Firmer surface creates a safer end feel for pt
  • Provides more stability
  • Partially or completely suspends the ischial tubs, sacrum, and coccyx
  • Redistributes pressure to areas that can withstand more pressure
28
Q

Considerations if using an offloading style cushion

A
  • NOT good for pts with trochanter wounds
  • May not be suitable for pts with hypersensitivity
  • Stable surface may be more difficult for independent transfers
  • Pt with contractures may not fit the pre-contoured shape
29
Q

Benefits of using an immersion cushion

A
  • Less firm surface ideal for pain management
  • Curvature increases pressure redistribution
  • Good for any type of pressure injury at any stage
  • May be easier for independent transfers
  • Reduces peak pressures at the bony prominences
30
Q

Considerations when using an immersion cushion

A
  • Less stable surface
  • May not be suitable for someone who desires proprioceptive input from a firmer surface
  • Some cushions require more maintenance & if not properly maintained can increase risk of a pressure injury

A
  • Check for tightened hamstrings
  • Check hip ROM
  • Check seat depth
  • Check seat to floor height
  • Check trunk stability & strength
