The effects of adapted spoons on food spilling and movement kinematics (movement duration, dysfluency) were examined in people with tetraparetic cerebral palsy (CP). We varied the thickness of the spoon's handle (diameters of 1, 3, and 5cm), the substance with which the spoon was filled (sugar or water), and the size of the bowl into which the spoon had to be emptied (diameter 5 or 11cm). Ten adolescents with tetraparesis (five males, five females; mean age 17y 2mo [SD 1y 3mo]; range 14y 7mo-18y 6mo) and 12 healthy comparison participants (four males, eight females; mean age 25y 6mo [SD 3y 0mo]; range 20y 0mo-30y 0mo) participated. Four participants with tetraparesis could walk independently, while the other six sat unstrapped in a wheelchair. The task consisted of picking up and transporting the filled spoon and emptying it into a bowl. Movements of the hand were recorded by a three-dimensional motion tracking device. When the spoon's handle was thickened participants with CP were faster in picking up the spoon and transporting it to the bowl, in particular when the spoon was filled with water. Importantly, this faster performance did not lead to increased spilling. These results are the first systematic test of the supposed beneficial effect of adapted spoons on movement performance in people with CP.
我们研究了适配勺子对四肢瘫型脑瘫（CP）患者食物溢出及运动学特征（运动持续时间、运动不流畅性）的影响。我们改变了勺子手柄的粗细（直径分别为1厘米、3厘米和5厘米）、勺子所盛物质（糖或水）以及勺子需倒入食物的碗的大小（直径5厘米或11厘米）。10名四肢瘫青少年（5名男性，5名女性；平均年龄17岁2个月[标准差1岁3个月]；范围14岁7个月至18岁6个月）和12名健康对照参与者（4名男性，8名女性；平均年龄25岁6个月[标准差3岁0个月]；范围20岁0个月至30岁0个月）参与了研究。4名四肢瘫参与者能够独立行走，而其他6名则未系安全带坐在轮椅上。任务包括拿起并运送装满食物的勺子，然后将其倒入碗中。手部运动由三维运动跟踪设备记录。当勺子手柄变粗时，CP患者拿起勺子并将其运送到碗中的速度更快，尤其是当勺子装满水时。重要的是，这种更快的操作并没有导致溢出增加。这些结果是对适配勺子对CP患者运动表现的假定有益效果的首次系统测试。
