22 Nov 2018 | | Abstract: | Pressure ulcers (PU) are known to be a high-cost disease with a risk of
severe morbidity. This work evaluates a new clinical strategy based on an
innovative medical device (Tongue Display Unit-TDU) that implements perceptive
supplementation in order to reduce prolonged excessive pressure, recognized as
one of the main causes of PU. A randomized, controlled, parallel-group trial
was carried out with 12 subjects with spinal cord injuries (SCI). Subjects were
assigned to the control (without TDU, n=6) or intervention (with TDU, n=5)
group. Each subject took part in two sessions, during which the subject, seated
on a pressure map sensor, watched a movie for one hour. The TDU was activated
during the second session of the intervention group. Intention-to-treat
analysis showed that the improvement in adequate weight shifting between the
two sessions was higher in the intervention group (0.84 [0.24; 0.89]) than in
the control group (0.01 [-0.01; 0.09]; p=0.004) and that the ratio of prolonged
excessive pressure between the two sessions was lower in the intervention group
(0.74 [0.37; 1.92]) than in the control group (1.72 [1.32; 2.56]; p=0.06). The
pressure map sensor was evaluated as being convenient for use in daily life,
however this was not the case for the TDU. This work shows that persons with
SCI could benefit from a system based on perceptive supplementation that alerts
and guides the user on how to adapt their posture in order to reduce prolonged
excessive pressure, one of the main causes of PU. | | Source: | arXiv, 1811.9106 | | Services: | Forum | Review | PDF | Favorites | |
