| Summary: | Background: People with stroke often suffer abnormal foot posture including
structural and movement deficiencies in the intrinsic foot segments on the
affected side, which are associated with limitation in mobility. As part of a
programme of research examining foot and ankle biomechanics after stroke, we
investigated plantar pressure distribution under the affected foot of people with
stroke and the relationship with functional mobility.
Methods: Plantar pressure distribution was investigated while standing and
walking on the affected side of twenty stroke and fifteen healthy sex and agematched participants, using a Medilogic platform system at a frequency of 20
HZ. Functional mobility in real life was measured using the Walking Handicap
Scale.
Results: While standing, people with stroke bore greater pressure on the
affected side through the lateral heel and lesser toes (P<0.01) and less at the
medial (MP1) and central forefoot (MP23) areas (P<0.05) than healthy controls.
During walking, more pressure was taken through the heel area, especially the
medial heel and less through the medial and central forefoot of the affected foot
of people with stroke compared to healthy controls.
The logistic regression model revealed that stroke participants who took greater
pressure on the medial heel while walking (odds ratio=1.11, P<0.05) had more
limited functional mobility (i.e. were more likely to be household walkers)
than those who did not. While standing, none of the standing plantar pressure
variables significantly contributed to the model.
Conclusion: The plantar pressure distribution differs significantly between the
affected foot of people with stroke and healthy controls. Abnormal plantar
pressure distribution while walking, but not while standing, is a significant
contributor to limited functional mobility post stroke. |
