To the Editor:—
The aged amputee must contend with feebleness and loss of ability to maintain balance. These account for many of the failures to provide these patients with satisfactory ambulation. While I was a patient in a rehabilitation center in a nearby city, I suggested to my bracemaker, William Bradley, the idea of a knee crutch. This he subsequently incorporated into an ordinary walker (Fig 1 and 2). This is primarily for the amputee who cannot be fitted with an artificial leg or who cannot use crutches satisfactorily. Feebleness is minimized and balance maintained with this type of prosthesis.
