Forty-three patients were fitted with a new all-plastic PTB orthosis over a period of 42 months. The diagnostic categories were primarily musculoskeletal impairments of the tibia and the ankle, with some instances of injury or disease of the plantar surface of the foot. Improvement in cosmesis, orthotic weight-reduction, ease of donning, marked relief of pain, and functional gains in ambulation were reported. No product failures occurred except for minor cracks in the distal plantar surface; replacements were provided to children within 11 to 14 months, and to adults within 19 to 24 months. Of the entire study population, only four preferred their previous long-leg braces that felt more secure after many years of use.
在42个月的时间里，为43名患者配备了一种新型全塑料PTB矫形器。诊断类别主要是胫骨和踝关节的肌肉骨骼损伤，也有一些足底表面受伤或患病的情况。据报告，在美观性、矫形器减重、穿戴便利性、疼痛明显缓解以及行走功能改善方面均有成效。除了足底远端表面出现轻微裂缝外，未发生产品故障；在11至14个月内为儿童更换，在19至24个月内为成人更换。在整个研究人群中，只有4人更喜欢他们之前使用多年后感觉更稳固的长腿支具。
