Statistical analysis
The median (IQR) was used to summarize postural stability scores. The semi-parametric cumulative probability (proportional odds) model was used to compare follow-up scores of the Balance group vs Control, and Coordination group vs Control, while adjusting for baseline values. All tests were two sided, with alpha set to 0.05. Multiplicity adjustment was done using the Bonferroni correction method. R version 3.6.1 and IBM SPSS v20 were used.
