NCT04330274

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.

Outcome Measures

Primary Outcomes (8)

  • 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.

  • 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 closed 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 without platform under heel.

    Change from baseline center of pressure at second 10, second 20 and second 30.
