43
A hemi-height wheelchair with a one-arm drive system.
Justification:
1. Hemi-Height Frame:
* Because of her short stature (4’11”), a hemi-height wheelchair allows her to reach the ground with her stronger (left) foot if she needs to foot propel. This is especially helpful for individuals with hemiplegia.
2. One-Arm Drive System:
* Since her right side is affected, she cannot effectively use both arms. A one-arm drive system (dual hand rims on the left wheel) allows her to propel and steer the wheelchair using only her left hand.
3. Clinical Fit:
* The note under “Stroke with hemiplegia” in the file implies matching chair specifications (seat height and propulsion system) to both motor ability and stature.
Conclusion:
A hemi-height wheelchair with a left-sided one-arm drive system would be the easiest and most functional choice for Mrs. Jones.

45
What are some WC alignment complications to be aware of?
46
Explain each line
* A – Seat Width:
Measures the width across the widest part of the hips or thighs when seated.
Taken with the patient sitting upright and relaxed.
Ensures the wheelchair is not too narrow (causing pressure) or too wide (leading to poor posture or lack of trunk stability).
* B – Seat Height (Floor to Popliteal Fossa):
Measures the distance from the floor to the back of the knee.
Taken while the patient is seated with thighs parallel to the floor.
Helps determine appropriate seat-to-floor height for proper leg positioning, safe transfers, and foot propulsion if needed.
* C – Footrest Length (Footplate Size):
Measures from the heel to the ball or toes of the foot.
Taken with the foot at 90° dorsiflexion.
Ensures the footplate supports the entire foot without overhang, which helps maintain ankle alignment and prevent foot drop.
* D – Seat Depth:
Measures from the back of the buttocks to the popliteal fossa (back of the knee).
Taken while seated with a neutral pelvis and knees at 90°.
Prevents excess pressure behind the knees and supports the thighs properly (subtract ~2” from actual length).
* E – Back Support Height:
Measures from the seat surface to the inferior angle of the scapula or desired height.
Taken while seated upright.
Used to determine the height of the backrest—lower for active users, higher for users needing trunk support.
* F – Seat to Floor Height:
Measures from the floor to the top of the wheelchair cushion or seat base.
Taken to match the height of furniture, surfaces, or floor clearance needs.
Affects transfers, foot clearance, and ability to propel with feet if applicable.
* G – Seat to Elbow Height:
Measures from the top of the seat to the bottom of the bent elbow (at 90°).
Taken with arms relaxed and shoulders in neutral position.
Determines armrest height to support the forearm and maintain shoulder alignment without shrugging or slumping.
* H – Elbow to Top of Shoulder:
Measures from the elbow (at 90° flexion) to the top of the shoulder.
Helps determine the length of lateral trunk supports or back supports if needed for posture or safety.
* I – Seat to Top of Shoulder:
Measures from the seat surface to the top of the shoulder.
Important for selecting the appropriate height for high backrests, harnesses, or postural support systems.
* J – Overall Seated Height:
Measures from the floor to the top of the head when seated.
Used to ensure the individual fits under desks, tables, doorways, and transportation vehicles.
* K – Shoulder Width:
Measures the width from one acromion (shoulder tip) to the other.
Taken with arms relaxed.
Guides lateral support placement and ensures proper fit for upper body positioning devices.
* L – Chest Width:
Measures the width across the upper chest or underarm area.
Helps determine appropriate harness or chest strap sizing if needed for trunk control or safety.
* M – Hip Width:
Redundant with “A” but viewed from the front.
Reconfirms seat width for optimal pelvic positioning and postural alignment.
* N – Thigh Length:
Matches “D” and confirms seat depth again, but from a front view.
Ensures thigh is properly supported without compressing the popliteal area.
* O – Calf Length (Popliteal Fossa to Heel):
Measures from the back of the knee to the heel.
Important for setting the footplate height correctly to avoid pressure on the back of the legs.
* P – Foot Length:
Measures the full length of the foot from heel to toes.
Used to make sure the footplate accommodates the foot properly without excess overhang or poor support.
