Effect of trunk control training on plantar pressure in patients with lumbar disc herniation

Abstract

Background/aims Chronic spinal disc disease leads to disorders in postural movement coordination. An incorrect asymmetrical movement pattern for lower limb loading impairs proprioception and deteriorates postural stability. The aim of this study was to investigate the effect of trunk control training on the redistribution of plantar pressure to reduce the risk of posture sway while standing in patients with sciatica resulting from a herniated lumbar disc. Methods This study included 30 male and female patients with sciatica resulting from lumbar disc herniation, their ages ranged from 45–60 years. The patients were randomly assigned to two equal groups. The study group received posture stability training by using the Biodex Balance System in addition to a selected physical therapy programme. The control group received the selected physical therapy programme only. Results: The results revealed that in the study group, there was a significant increase of plantar pressure at the right and the left centre of heel, while there was a significant decrease of plantar pressure at the right and the left forefoot post treatment. In the control group, there was no significant difference in plantar pressure at the right and the left centre of the heel and forefoot post treatment. Conclusions: Trunk control training, in addition to the selected physical therapy programme, was more effective than only using the selected physical therapy programme to redistribute foot plantar pressure, which can reduce posture sway for patients with sciatica resulting from a herniated lumbar disc.
