Review of toe walking that lists physical therapy and gastrocnemius stretching among conservative options; notes the strongest evidence is for casting and surgery, so stretching is a low-risk first-line measure rather than a proven cure.

Peterson KM, Piazza CC, Volkert VM (2016) J Appl Behav Anal [PMID 27449267]

Small RCT (n=6, children with ASD): a modified SOS sensory approach did not increase food consumption while a behavior-analytic approach (graduated exposure with reinforcement) did.
