Comparison of Different Amputation Levels

Study Overview
=================
Brief Summary
-----------------
Lower limb amputation is a factor that changes the individual's weight transfer, gait pattern, and trunk balance. This change plantar pressure distribution of both side and cause a series of problems to be exposed over time according to level of amputation. The aim of this study is to reveal the relationship between amputation level-postural balance and amputation level-plantar pressure distribution.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Measurement of plantar pressure distrubution | Plantar pressure distrubution (mmHg/N) will be measured by force platform (F-Scan 6.70 TekScan, Boston, MA) on bipedal with open eyes | Change from baseline plantar pressure distrubution at second 10, second 20 and second 30. | 
| Measurement of plantar pressure distrubution | Plantar pressure distrubution (mmHg/N) will be measured by force platform (F-Scan 6.70 TekScan, Boston, MA) on bipedal with platform under heel | Change from baseline plantar pressure distrubution at second 10, second 20 and second 30. | 
| Determination of center of pressure | Determination of center of pressure (cm) will be provided by force platform (F-Scan 6.70 TekScan, Boston, MA) on bipedal with open eyes | Change from baseline center of pressure at second 10, second 20 and second 30. | 
| Determination of center of pressure | Determination of center of pressure (cm) will be provided by force platform (F-Scan 6.70 TekScan, Boston, MA) on bipedal with platform under heel. | Change from baseline center of pressure at second 10, second 20 and second 30. | 
| Measurement of plantar pressure distrubution | Plantar pressure distrubution (mmHg/N) will be measured by force platform (F-Scan 6.70 TekScan, Boston, MA) on bipedal with closed eyes | Change from baseline plantar pressure distrubution at second 10, second 20 and second 30. | 
| Measurement of plantar pressure distrubution | Plantar pressure distrubution (mmHg/N) will be measured by force platform (F-Scan 6.70 TekScan, Boston, MA) on bipedal without platform under heel | Change from baseline plantar pressure distrubution at second 10, second 20 and second 30. |
