In an institution for the mentally retarded, an uncontrolled study was made on the effects of d-amphetamine, d-amphetamine followed by trifluoperazine, and of combined d-amphetamine and trifluoperazine on stuttering. Of 28 patients to whom d-amphetamine was given, 14 showed improvement after one month's treatment. Eight more showed improvement when trifluoperazine was given for one month to those who did not improve on d-amphetamine. In many cases, improvement was sustained at least six months after treatment was discontinued. Treatment with d-amphetamine was apparently more effective in patients with functional than with organic retardation.
在一所智障机构中，对右旋苯丙胺、先使用右旋苯丙胺再使用三氟拉嗪以及右旋苯丙胺与三氟拉嗪联合使用对口吃的影响进行了一项非对照研究。在接受右旋苯丙胺治疗的28名患者中，14名在治疗一个月后有改善。在接受右旋苯丙胺治疗无改善的患者中，有8名在接受三氟拉嗪治疗一个月后有改善。在许多病例中，治疗停止后改善情况至少持续了六个月。右旋苯丙胺治疗对功能性智障患者显然比对器质性智障患者更有效。
