目的.本研究的目的是比较四肢瘫痪患者的地上和踏车推进模式。在本病例系列研究中，我们招募了8名四肢瘫痪的成年受试者（5名男性和3名女性，年龄32.5 ± 9.5岁）。所有受试者均使用手动轮椅。我们使用视频动作捕捉系统来记录受试者在地面和跑步机上手动转动时的动作。我们将推进模式分为四种模式之一，并测量了每种模式的五个不同的几何变量。我们使用方差分析进行统计学比较。在最大高度/最大长度× 100（H/L%）上，（平均20% +/- 15.3/左手，平均21.3% +/- 16.5/右手）与跑步机表面上的推进力（滚筒：平均30.9% +/- 11.2/左手，平均33.5% +/- 12.8/右手;腰带：平均27.7% +/- 8.7/左手，平均34.9% +/- 14.2/右手）和左右手之间。结果表明，三种表面类型的面积和H/L%不同，左右侧也不同。在将跑步机结果外推到地面上的推进力或假设双侧对称时，必须谨慎。
Purpose. The purpose of this investigation was to compare overground and treadmill propulsion patterns in persons with tetraplegia.Methods. In this case series study, we recruited eight adult subjects with tetraplegia (5 men and 3 women, aged 32.5 +/- 9.5). All subjects used manual wheelchairs. We used a video motion capture system to record movements as the subject manually wheeled overground and on a treadmill. We classified propulsion patterns into one of four patterns and measured five different geometric variables of each pattern. We compared them statistically using ANOVA.Results. There were significant differences in max height/max length x 100 (H/L%) between propulsion over ground (mean 20% +/- 15.3/Lhand, mean 21.3% +/- 16.5/Rhand) versus propulsion on treadmill surfaces (roller: mean 30.9% +/- 11.2/Lhand, mean 33.5% +/- 12.8/Rhand; belted: mean 27.7% +/- 8.7/Lhand, mean 34.9% +/- 14.2/Rhand) and between the left and right hand.Conclusion. Results indicated area and H/L% were different among the three surface types and between right and left sides. Caution must be used in extrapolating treadmill results to propulsion over ground or in assuming bilateral symmetry.
