PURPOSE: The goal of this study was to monitor and describe the use of power tilt
systems in everyday life. Additionally, tilt measurements were used to determine
if participants performed regular pressure relieves.
METHODS: Wheelchair occupancy and seat position of 16 fulltime power wheelchair
users were monitored regularly for 1-2 weeks. Daily wheelchair occupancy, typical
position, time spent at different tilt angles, tilt frequency and pressure
relieving tilt (PRT) frequency were described.
RESULTS: Participants used their tilt systems in many different ways, including
subjects who typically sat at small (0-14 degrees) tilt angles and subjects who
typically sat at medium (15-29 degrees) tilt angles. Few subjects tilted past 45
degrees. Almost all subjects tilted throughout the day, with the median subject
performing >3 tilts per hour of wheelchair occupancy. Despite the regular use,
few subjects performed regular PRTs (median = 0.13/h)
CONCLUSION: Differences in tilt-use illustrated the variability in function and
activity among users, as well as the diverse benefits of a tilt system for
different users. Further study into why subjects did not regularly achieve PRT
magnitudes would be valuable to inform improved training, education and
follow-up.
