[Purpose] The purpose of the present study was to examine differences in the sequence of movements of stroke patients performing sit-to-walk (STW) among various foot positions and chair. [Subjects] The subjects of the present study were 11 stroke patients and a control group of 11 subjects, with no significant differences in sex, age, height, weight and body mass index between the two groups were randomly selected. [Methods] STW tasks were performed under four different conditions: high seat with feet forward, high seat with feet backward, normal seat with feet forward and normal seat with feet backward) with different foot positions and chair heights. The STW tasks were divided into four phases and the sequences of STW movements during the phases were analyzed. The phases were as follows: rise preparation, transition, primary gait initiation, and secondary gait initiation. [Results] In the condition of the high seat with feet backward, decreases in the center of mass (COM) horizontal momentum were the smallest at the time point of ending of the rise preparation phase, and moving speeds and distances between the COM and the center of pressure (COP) significantly increased at swing leg toe-off which is at the end of the primary gait initiation phase.[Conclusion] Changes in the movement pattern of COM horizontal momentum were the most efficient when rising from chair of a height of 120% of the leg length, and COM horizontal momentum was maintained until swing leg toe-off in this condition. When practicing STW functional movements in the clinical setting, the foot positions and chair heights necessary to maintain the sequence of movements should be considered.
