- KCT0006927
- Brief Summary
1) Gait adaptation pattern during uphill gait Stride length and stride time showed no statistically significant changes as slope angle increased during uphill gait, while the affected leg showed longer step length (p<0.01) in terms of interaction effect by limb compared to the unaffected leg. Step length of the unaffected leg did not show any statistical significance during inclination angle change. (Table I) For kinematic variables, both the affected and the unaffected leg showed overall increasing tendency of flexion of hip, knee and ankle joints. While hip and ankle joints of both limbs showed similar results during most of the gait cycle except pre-swing phase as the slope angle steepened(p<0.05), the knee joint showed a significant difference between two legs at different gait cycles. Affected leg showed more flexion during terminal swing to initial contact phase, while the unaffected leg showed increased flexion during most of stance phase(p<0.05) (Figure 1) 2) Gait adaptation pattern during downhill gait During downhill gait, statistically significant decrease in stride length and stride time were observed as slope deepens (p<0.01). While stance time of both limbs showed significant decrease(p<0.01), swing time of both limbs did not show significant change as slope angle gets deeper. The affected leg showed shorter step length as slope deepens (p<0.01), while the unaffected leg did not show significant change. In summary, step length showed statistically significant changes during both uphill and downhill gait only at the affected leg as inclination angle changed. (Table II) Analysis of kinematic variables showed more flexion of the affected leg at hip and knee joints at early swing phase, while the unaffected leg only showed increased flexion of knee joints (p<0.05). Ankle plantarflexion was more performed during stance phase of the unaffected limb, while the affected limb did not (Figure 2).
