Abstract		Objective: To compare the spatio-temporal gait parameters of stroke subjects walking on a treadmill and overground. Design: Same subject-self controlled study. Setting: Gait analysis laboratory of the rehabilitation institute. Participants: Convenience sample of 10 independently ambulant stroke subjects recruited from the stroke patients discharged from rehabilitation. Interventions: Treadmill and overground walking. Main Outcome Measures: Spatio-temporal and joint kinematic gait parameters. Results: Walking on the treadmill demonstrated lower cadence (p<0.0001), longer step times of the nonhemiplegic (p<0.001) and hemiplegic (p<0.01) limb, longer absolute stance times ofboth limbs (both p< 0.01) and longer absolute double support time (p<0.001) compared to overground walking. Also relative stance time (p<0.05) and relative double support time (p<0.001) were longer, and relative single support time of the nonhemiplegic limb (p<0.05) was shorter on the treadmill. The nonhemiplegic limb's knee and hip were more flexed at initial contact (p<0.05 and p<0.01, respectively), maximal extension of the hemiplegic limb's hip was lower (p<0.05), and maximal hip flexions of both limbs were greater during walking on the TR. The maximal herniplegic limb's ankle plantarlexion and knee extension occurred later in the gait cycle (both p<0.05) on treadmill than overground. Conclusions: Walking on a treadmill results in different spatio-temporal and kinematic gait characteristics to walking overground. Therefore, caution is needed when using treadmill training to improve a gait pattern. It may however be useful to use treadmill in conjunction with overground walking to focus on improving specific walking deficits.
