What is the primary purpose of maintaining proper lumbar support in a seating system?
Increase thoracic kyphosis
Maintain the natural lumbar curve
Relieve pressure on the head
Promote posterior pelvic tilt
Proper lumbar support preserves the natural lordotic curve of the lower spine, which helps distribute load and reduce disc pressure. This support promotes a neutral spinal alignment and decreases muscle fatigue.
Which anatomical landmark is most commonly used to assess pelvic alignment in seating?
Anterior superior iliac spine (ASIS)
Lateral malleolus
Acromion process
Greater trochanter
The ASIS is a palpable bony landmark used to assess pelvic tilt and obliquity. Comparing ASIS height on each side helps identify imbalances in pelvic alignment.
What is the recommended angle between the femur and torso in an optimal sitting posture?
135°
90°
45°
120°
A 90° hip angle helps maintain neutral pelvic alignment and minimizes shear forces on tissues. This right angle also supports optimal weight distribution.
Which cushion material is known for its ability to conform and distribute pressure evenly?
Gel
Air-cell
Memory foam
High-density foam
Memory foam (viscoelastic foam) contours to individual body shapes under heat and pressure, reducing peak loads. It redistributes pressure evenly across the seating surface.
When seated properly, most of the user's weight is borne by which anatomical structure?
Ischial tuberosities
Femoral heads
Sacrum
Coccyx
The ischial tuberosities (sit bones) are the primary weight-bearing points in seated posture. Proper alignment ensures these structures support the load without excessive pressure on other tissues.
Which seating alignment promotes a neutral spinal posture in a wheelchair seat?
Ankles higher than knees
Equal hip and knee height
Knees higher than hips
Hips slightly higher than knees
Positioning the hips slightly above the knees helps maintain lumbar lordosis and reduces posterior pelvic tilt. This alignment supports a neutral spine and comfortable posture.
What capillary closure pressure threshold must be monitored to prevent pressure ulcers?
45 mmHg
16 mmHg
22 mmHg
32 mmHg
Pressures above 32 mmHg can occlude capillaries and lead to tissue ischemia. Monitoring interface pressures around this threshold helps in pressure injury prevention.
What repositioning interval is typically recommended to minimize pressure injury risk in seated individuals?
Once daily
Every 15 - 30 minutes
Every 4 hours
Every 60 minutes
Repositioning every 15 - 30 minutes reduces prolonged pressure on vulnerable tissues. Frequent weight shifts help maintain blood flow and prevent pressure injuries.
How does a posterior pelvic tilt affect spinal curvature?
Reduces sacral sitting
Neutralizes spinal curves
Increases thoracic kyphosis
Increases lumbar lordosis
A posterior pelvic tilt flattens the lumbar curve and often causes compensatory increased curvature (kyphosis) in the thoracic spine. This misalignment can contribute to discomfort and deformity over time.
Which restraint component is most effective in preventing lateral trunk lean in a reclining chair?
Abductor pommel
Footplates
Headrest
Lateral trunk supports
Lateral trunk supports positioned on each side of the torso stabilize the trunk and prevent lateral leaning. They help maintain midline posture in a reclining position.
Which seating contour helps reduce sacral sitting in a wheelchair?
Forward slope
Anti-thrust seat
Posterior slope
Flat seat
An anti-thrust (or front wedge) seat design prevents posterior sliding by tilting the front edge upward. This reduces sacral sitting and maintains pelvic position.
When customizing a cushion, which patient-specific factor is most critical to consider according to evidence-based guidelines?
Seat height
Fabric type
Cushion color
Individual weight distribution
Patient weight distribution guides cushion selection and contouring to offload high-pressure areas. Evidence-based seating relies on pressure mapping data tailored to the user's anatomy.
How should seat depth be measured for optimal thigh support?
From ischial tuberosity to mid-thigh
From coccyx to heel minus 1 cm
From ASIS to fibular head
From posterior buttock to popliteal fossa minus 2 - 3 cm
Subtracting 2 - 3 cm from the full thigh length ensures clearance behind the knee and avoids pressure on the popliteal area. This promotes circulation and comfort.
What is the role of thixotropic materials in seating cushions?
Increase viscosity under shear forces
Remain constant regardless of pressure
Become more fluid under pressure then regain viscosity when static
Harden permanently after weight application
Thixotropic materials thin under shear (pressure) to conform to body shapes and then regain viscosity when pressure is relieved. This property aids pressure redistribution and support.
In an anterior pelvic tilt seating posture, which muscle group is passively lengthened?
Hamstrings
Hip flexors
Abdominal muscles
Gluteal muscles
An anterior tilt increases the angle at the hip, placing the hamstrings on stretch. Proper seating can help manage muscle length and tension.
For a patient with a fixed posterior pelvic tilt, which seat cushion feature best assists in achieving neutral pelvic alignment?
Flat seat cushion
Posterior seat wedge
Anterior seat wedge
Rigid cushion
An anterior wedge lifts the front of the pelvis, counteracting a posterior tilt and promoting a more neutral alignment. This can improve posture and weight distribution.
Biomechanically, how does increasing the seat back angle beyond 100 degrees generally influence shear forces on the user's skin?
Increases shear only at the ischium
Increases shear forces
Has no effect on shear forces
Reduces shear forces
Reclining the backrest beyond 100° redistributes body mass, reducing downward sliding and shear forces at the skin interface. This is beneficial for pressure injury prevention.
Which anthropometric ratio is used to estimate the degree of pelvic obliquity during seating assessment?
Hip-knee-ankle angle ratio
Difference in ASIS height divided by distance between ASIS landmarks
Gluteal fold angle ratio
Thoracic to lumbar height ratio
Calculating the vertical ASIS height difference over the inter-ASIS width provides a normalized measure of pelvic obliquity. This ratio helps quantify asymmetry in clinical assessments.
In pressure mapping for custom seating design, what percentage above the mean interface pressure indicates areas that require additional support or relief?
100%
80%
140%
120%
Regions showing pressures above 120% of the mean are considered high-risk and may need extra cushioning or relief. Targeting these hotspots improves tissue protection.
According to seating ergonomics guidelines, what is the optimal backrest inclination angle to redistribute pressure for high-risk patients?
90 degrees
130 degrees
100 degrees
110 degrees
A backrest angle around 110° redistributes pressure away from the sacrum toward larger surface areas. This semi-reclined position enhances comfort and reduces ulcer risk.
