Table 5 Change in ambulation during treatment and comparison with untreated controls using the Wilson scale of nine levels: 1, functional walking without aid in all surroundings, to 9, sitting with support but no locomotion9.

The Bleck scale of five levels is shown in parenthesis: 0 non‐walker to 4 community walker.
*The improvement seen at the latest recording in treated patients is significant (p⩽0.001) compared to both pretreatment values and the untreated age‐matched controls.
