Abstract

現在,トレッドミル歩行は,省スペースで連続歩行が可能であるいう理由から,片麻痺患者や脊髄損傷患者などに多く利用されている評価・練習方法である。本研究の目的は,トレッドミル歩行における臨床的応用の予備的検討として,トレッドミル歩行と平地歩行の比較を運動力学的因子,特に床反力に着目して検討することにある。健常成人28名に対し,主観的な判断として「遅い」,「快適」,「速い」の3速度で平地歩行時とトレッドミル歩行時の床反力(垂直分力,前後分力,左右分力)を計測した。両歩行の床反力波形の類似性は,3分力ともに類似性の高い結果となった(r=0,76〜0,95)。床反力波形のピーク値の比較では,垂直分力第3ピーク値と前後分力第1ピーク値において3速度ともトレッドミル歩行の方が有意に低い値を示した(p<0.01)。これらの結果から,トレッドミル歩行と平地歩行には,相違点がいくつか認められたものの,床反力波形の全体としての類似性は高く,事前の予備練習や歩行速度の調整を行い環境的要因のことを考慮した上でトレッドミルを用いれば,有用な代替的手法になると考えられた。

Treadmill walking is often used and draws attention as a method to evaluate and exercise patients with hemiplegia and those with spinal cord injury, as it does not take up much space and enables continuous walking. The purpose of this study was to investigate the difference in kinetic factors, especially ground reaction force, between treadmill and overground walkings in order to examine the viability of treadmill walk before employing it in a clinical setting. Subjects were 28 healthy adults. They were asked to walk both on the treadmill and on the overground at three subjectively different speeds; slow, comfortable and fast. We measured ground reaction force; vertical component of force, force and after component of force, and lateral component of force, at each of the speeds of the both walkings. Both the treadmill and overground walkings presented similar ground reaction force wave forms in all of the three components of force with r = 0.76 to 0.95. Concerning the comparison among peak values of the ground reaction force, the third peak value of the vertical component of force and the first peak value of the force and after component of force of the treadmill walking were significantly lower than those of the overground walking at any of the three different speeds (p<0.01). The results of the study show that while treadmill and overground walkings are two different kinds of walkings, both walkings presented similar wave forms of ground reaction force as a whole. Treadmill walking, with preliminary exercise and walk speed adjustment as a prerequisite, and taking environmental factors into consideration, could be used as a useful alternative to overground walking.
