ABSTRACT
OBJECTIVES: OBJECTIVES: OBJECTIVES: OBJECTIVES: To investigate changes in pressure distribution after sensorimotor training
and the changes in muscle timing in normal subjects and diabetic patients.
DESIGN: DESIGN: DESIGN: DESIGN: A portable four channel electromyographic system (Noraxon) has been
synchronised in real time with the PEDAR® in-shoe pressure measurement system.
BACKGROUND: BACKGROUND: BACKGROUND: BACKGROUND: Until now, peak pressures under the diabetic foot have generally
been investigated via the application of orthopaedic insoles. To date nobody has
published objective information of sensorimotor training in relationship to foot pressure
distribution for the diabetic foot.
METHODS: METHODS: METHODS: METHODS: Three groups of subjects have been studied, a normal reference group
(n=23), a randomly assigned diabetic intervention group (n=24), and a diabetic
control group (n=20), by recording electromyography of the lower leg muscles and in-
shoe foot pressure measurements simultaneously. RESULTS: RESULTS: RESULTS: RESULTS: After a period of 6 weeks of daily training with an unstable shoe
construction (USC) peak pressure under metatarsal heads 1, 2/3, and big toe were
lower but higher for metatarsal heads 4/5 in group 1. Group 2 showed a reduction in
peak pressure and the pressure-time integral under the first metatarsal head and a
tendential increase in peak pressure in the midfoot. Group 3 did not show any
significant changes in peak pressure but a delayed peak muscle activity for the
anterior tibialis muscle.
CONCLUSION: CONCLUSION: CONCLUSION: CONCLUSION: Sensorimotor function is an important parameter in the study of foot
pressure distribution under the normal and the diabetic foot which can be trained to
reduce foot loading by 16%, especially in the most endangered region of the diabetic
foot, the medial forefoot.
