Stem cell therapy
Cochrane reviews have found no evidence of effectiveness of stem cell-based interventions for the prevention of morbidity and mortality in newborns born preterm or in newborns after hypoxic‐ischaemic encephalopathy.[209]Romantsik O, Bruschettini M, Moreira A, et al. Stem cell-based interventions for the prevention and treatment of germinal matrix-intraventricular haemorrhage in preterm infants. Cochrane Database Syst Rev. 2019 Sep 24;(9):CD013201.

There are no government-approved uses for stem cells in the treatment of CP in developed countries. Stem cell tourism (the travel of patients and their families in pursuit of such treatments) is discouraged by ethical practitioners.
Transcranial magnetic stimulation (TMS) and transcranial direct current stimulation (tDCS)
These are non-invasive methods of stimulating and modulating neural circuits of the motor cortex by placing induction coils (TMS) or electrodes (tDCS) on the skull. TMS is used primarily in mapping brain circuits, but has also been used therapeutically for patients with CP.[215]Hameed MQ, Dhamne SC, Gersner R, et al. Transcranial magnetic and direct current stimulation in children. Curr Neurol Neurosci Rep. 2017 Feb;17(2):11.

Evidence suggests that adding repetitive TMS, with or without constraint-induced movement therapy, enhances therapy-induced functional motor gains in children with hemiparetic CP.[216]Kirton A, Andersen J, Herrero M, et al. Brain stimulation and constraint for perinatal stroke hemiparesis: The PLASTIC CHAMPS Trial. Neurology. 2016 May 3;86(18):1659-67.

tDCS has been trialled in patients with CP, with some promising results.[217]Fleming MK, Theologis T, Buckingham R, et al. Transcranial direct current stimulation for promoting motor function in cerebral palsy: a review. J Neuroeng Rehabil. 2018 Dec 20;15(1):121.

Both TMS and tDCS are currently being considered investigative in paediatric populations.[215]Hameed MQ, Dhamne SC, Gersner R, et al. Transcranial magnetic and direct current stimulation in children. Curr Neurol Neurosci Rep. 2017 Feb;17(2):11.

Peripheral nerve magnetic stimulation has also been utilised and is claimed to have an effect on the motor cortex, with the effects outlasting the treatment sessions.[219]Flamand VH, Schneider C. Noninvasive and painless magnetic stimulation of nerves improved brain motor function and mobility in a cerebral palsy case. Arch Phys Med Rehabil. 2014 Oct;95(10):1984-90.
