Six diabetic patients with neuropathic ulceration of the sole of the foot (seven feet, eight ulcers) were treated by the application of a below knee walking plaster with a rubber rocker. All the ulcers healed with this treatment, greatly reducing the usual period of hospital inpatient stay. After healing, study of the forces acting on the sole of the foot showed that these ulcers occur at the site of maximal horizontal shear force and confirmed that they occur at the site of maximal vertical force. This treatment is highly effective for neuropathic ulcers of the sole not affecting bone or complicated by deep sepsis. There may be a high rate of recurrence, however, reflecting inadequacy of methods of protecting damaged neuropathic feet.
六名患有足底神经性溃疡的糖尿病患者（七只脚，八个溃疡）接受了带有橡胶摇椅的膝下行走石膏治疗。所有溃疡经此治疗均愈合，大大缩短了通常的住院时间。愈合后，对作用于足底的力进行研究表明，这些溃疡发生在最大水平剪切力的部位，并证实它们发生在最大垂直力的部位。这种治疗方法对不影响骨骼或未并发深部脓毒症的足底神经性溃疡非常有效。然而，复发率可能很高，这反映出保护受损神经性足部的方法存在不足。
