Kinematic aspects of the reduced shooting ability of tetraplegic (TP) wheelchair basketball players were investigated and compared with those of able-bodied (AB) basketball players. TP showed significantly smaller values for the vertical component of ball release velocity (4.26 (degree/s) versus 5.45 (degree/s)) and maximum wrist flexion angular velocity (878.4 (degree/s) versus 1445.9 degrees) than AB. Moreover, for a specific shoulder horizontal adduction motion, a larger range of shoulder abduction motion and larger displacements of the right shoulder were observed in TP. The reduced ball velocity of TP subjects with lesions at the C7 to C8 levels depended on an insufficient wrist flexion angular velocity, where dysfunction of available musculature may be a causal determinant. Further, the specific motions observed in TP subjects most likely maximize the function of available musculature, thereby partially compensating for the dysfunction of the wrist flexor muscles and contributing to resultant ball release velocity.
对四肢瘫痪（TP）轮椅篮球运动员投篮能力下降的运动学方面进行了研究，并与健全（AB）篮球运动员进行了比较。与AB组相比，TP组在球出手速度的垂直分量（4.26（度/秒）对5.45（度/秒））和最大腕关节屈曲角速度（878.4（度/秒）对1445.9度）方面的值明显更小。此外，对于特定的肩部水平内收运动，在TP组中观察到更大范围的肩部外展运动和右肩部更大的位移。C7至C8水平损伤的TP受试者的球速降低取决于腕关节屈曲角速度不足，其中可用肌肉组织的功能障碍可能是一个因果决定因素。此外，在TP受试者中观察到的特定运动最有可能使可用肌肉组织的功能最大化，从而部分补偿腕屈肌的功能障碍并有助于最终的球出手速度。
