Alternate four-point sweep-through gait--a technique for patients with combined neuromuscular and visual impairments:...

This article reports on two patients with combined neuromuscular and visual impairments who used a modification of the classic alternate four-point crutch gait, which allowed them to simultaneously explore the upcoming environment for obstacles or change in terrain while maintaining sufficient support for their lower limbs. The technique should be useful for patients with diabetic neuropathy/retinopathy combinations, multiple sclerosis with optic neuritis, and neurosarcoidosis and in elderly patients with multiple disabilities.
