Background:
The motor functions of Rett syndrome patients degrade during the course of the disease. Some patients, however, are able to maintain their motor functions by undertaking exercise programs.
Case:
A 2-year-old girl was diagnosed with Rett syndrome after the identification of a mutation in the gene encoding the methyl-CpG-binding protein. The patient started weekly rehabilitation therapy; however, over time, this reduced to monthly sessions, and subsequently, because of worsening epileptic seizures, even fewer sessions were possible. When the patient was 12 years old, intensive rehabilitation therapy was undertaken for 1 month; therapy involved 80 min of in-hospital therapy on weekdays and walking exercises at home at the weekend. An accelerometer (Actiwatch 2, standard type, Philips Respironics) indicated that more than 60 min of daily training at an intensity of 3 metabolic equivalents (METs) or more was achieved at weekends. The patient took the 10-m walk test, and the average time reduced from 18.6 to 13.5 s and the number of steps reduced from 32 to 23 between the start and finish of the first 1-month intensive training regime. After being discharged from the hospital, the patient maintained walking exercises at school during weekdays and performed more than 50 min/day of activity at at least 3 METs at home on weekends, in addition to a weekly home-visit rehabilitation therapy and the annual in-hospital 1-month rehabilitation therapy. Four years later, the patent's average time and number of steps required to walk 10 m remained lower (12.7 s, 24 steps) than those recorded at the first evaluation.
Discussion:
Periodic rehabilitation therapy and proactive walking exercises at more than 3 METs for a duration of up to 50 min/day were instrumental in maintaining the motor functions of a Rett syndrome patient.
