    Abstract:

    Abstract: Objective: To investigate the changes of plantar pressure distributions and risk of falling before and after the occurrence of neurogenic intermittent claudication (NIC) in patients with central lumbar spinal stenosis, so as to provide valuable references for walking abilities of the disease in future plantar pressure analysis studies. Methods: 12 patients with LSS at the L4/5 level were selected as the LSS group, while 12 healthy adults at the same age were selected as the control group. Footscan system was used to measure the plantar pressure of these subjects during walking. Contact area percentage of the total foot contact area (CA%), pressure-time integral (PTI), foot progression angle (FPA), contact time percentage of the stance time (CT%) and total stance time (CT) in both LSS group and control group were compared to evaluate changes of the plantar pressures during walking.Results: Before the occurrence of NIC, compared with the control group, the LSS group has lower CT% of the forefoot push-off phase (FFPOP) and higher CT% of the initial contact phase (ICP), the total CT and FPA also increased, and the PTI of the 1st to 3rd metatarsals and the CA% of the 2nd and 3rd metatarsals were higher. After the NIC occurred, the results of the LSS group shows that the CT% of the initial contact phase (ICP) and forefoot contact phase (FFCP) decreased, the CT% of the foot flat phase (FFP) and forefoot push-off phase (FFPOP) as well as total CT and FPA increased, the PTI and CA% increased in 1st to 4th metatarsals, moreover, the CA% also increased in toe zone, both of the PTI and CA% decreased in heel zone. Conclusions: In patients with central LSS, the distribution of plantar pressure shifts forward and the abnormal phase of the stance time occurs, moreover, the abnormality could be further aggravated by NIC, which indicates a higher risk of falling.
