To understand kinetic characteristics during the process of initiation of gait from standing, from the visual cue to toe off of the stance limb, vertical ground reaction forces(GRF) during gait initation period were evaluated with two force platforms placed side by side in thirteen adults(7 males, 6 females, mean age 29.3 years) with no history of neuromusculo-skeletal abnormality. Gait initiation period of swing and stance limbs, percentage of gait initiation period and ratio of the vertical forces to body weight at each peak of the vertical forces of both limbs were measured and described. These data can now be used as a part of databases when initiation of gait in subjects with neuromusculoskeletal abnormalities need to be evaluated.

Among various test methods for evaluation of postural control, posturography(PG) using force platform is well known as one of the most quantitative, sensitive and convenient method in normal subjects and in patients with impaired postural control. The purpose of this study was to obtain the effect of vision, proprioception and auditory stress on postural control in normal and hemiplegic adults, to compare postural control of normal with that of hemiplegic and to get characteristics of postural control in hemiplegics. We recorded the movement of the center of gravity for 45 seconds on force platform in 20 normal and 10 hemiplegic adults under the conditions of eye-open or eye-closed on the stable surface and on the hard sponge, and processed these data using posturography software to acquire 5 parameters of posturography, i.e. maximal sway(mm), trace length(mm), speed (mm/sec), area(mm^2) and its mean radius(mm). The results were as follows : 1) In normal adults, visual deprivation only didn't cause any loss of balance and under impaired proprioception 3 parameters(maximal sway, mean radius and area) of PG were increased. Both visual and proprioceptive loss, when balance is controlled by only vestibular function, caused the increase of the 5 parameters of PG. 2) In the hemiplegics, without visual influence on balance, speed and trace length were increased and by interfering proprioception or both vision and proprioception, 5 parameters of PG were increased. 3) Compared with normal adults, hemiplegics showed the impaired postural control, especially in the maximal sway, mean radius and area of PG. 4) Auditory stress didn't affect postural control of normal adults. With the results above, postural control of normal and hemiplegic adults were affected by propriception more than vision, and auditory stress didn't affect postural control of normal adults. Compared with normal adults, hemiplegics showed the impaired postural control.
