PURPOSE: To characterise the use of tilt-in-space systems and to form
recommendations for tilt prescription and training based upon its use. METHOD:
Wheelchair occupancy and seat position of 45 full-time power wheelchair users
were monitored for 1-2 weeks using an accelerometer, occupancy switch and data
logger. Demographics, pressure ulcer history, functional and physical
presentations of their disability, and sensation were also documented. RESULTS:
Participants spent 12.1 h in their wheelchairs daily, with a median typical
position of 8 degrees (0 degrees -47 degrees ).
The median participant tilted
every 27 min (0.1-16.6 tilts per occupancy hour). Pressure-relieving tilts (i.e.
a tilt >/=30 degrees for >/=1 min) were performed, on average, once every 10 h
(0-2.2/h). Participants spent 19% of their seated time tilted past 15 degrees .
Seventeen participants utilised the tilt feature frequently and spent >20% of the
time in multiple positions.
The remaining participants sat in a single tilt range
for >80% of the time. CONCLUSIONS: Given the limited pressure relief compliance,
alternative approaches to pressure relief and improved training may be needed for
some clients. Wheelchair design and prescriptions may also need to reflect
participants' preferences for sitting in small and medium tilts and changing
position frequently.
