Ten participants underwent two electrical stimulation (ES) protocols
applied using a custom-made electrode garment with built-in electrodes. Interface
pressure was measured using a force-sensitive area. In one protocol, both the
gluteal and hamstring (g+h) muscles were activated, in the other gluteal (g)
muscles only.Objectives:To study and compare the effects of electrically induced
activation of g+h muscles versus g muscles only on sitting pressure distribution
in individuals with a spinal cord injury (SCI).Setting:Ischial tuberosities
interface pressure (ITs pressure) and pressure gradient.Results:In all
participants, both protocols of g and g+h ES-induced activation caused a
significant decrease in IT pressure. IT pressure after g+h muscles activation was
reduced significantly by 34.5% compared with rest pressure, whereas a significant
reduction of 10.2% after activation of g muscles only was found. Pressure
gradient reduced significantly only after stimulation of g+h muscles (49.3%). g+h
muscles activation showed a decrease in pressure relief (Delta IT) over time
compared with g muscles only.Conclusion:Both protocols of surface ES-induced of g
and g+h activation gave pressure relief from the ITs. Activation of both g+h
muscles in SCI resulted in better IT pressure reduction in sitting individuals
with a SCI than activation of g muscles only. ES might be a promising method in
preventing pressure ulcers (PUs) on the ITs in people with SCI. Further research
needs to show which pressure reduction is sufficient in preventing PUs.
