Abstract:
Objective To investigate time distribution of pressure of footplate in each stage and vertical anti-force from ground of patients with knee osteoarthritis (KOA).Methods 40 KOA patients, 10 aged people, and 10 common saplings were selected to test time distribution of pressure of footplate in each stage and vertical anti-force from ground in period of monopodia support.Results To unilateral KOA patient, there was not obvious difference to be observed in initial contact phase and forefoot push off phase ( P>0.05), but there was a significant difference in forefoot contact phase and foot flat phase between health side and sick side ( P<0.001), and there was obvious difference decreased buffer time and buffer force coefficient between them ( P<0.01).Conclusion To KOA patients, the time decreases in weight-bearing phase and absorption shocks, and amortization coefficient also decreases. These indexes can be used as the walking index of functional assessment and the objective evidence of curative effect.
