Table 3 Group differences in muscle architecture, walking function and muscle strength on group-level, presented as median and interquartile range (IQR)

From: Ballistic strength training in adults with cerebral palsy may increase rate of force development in plantar flexors, but transition to walking remains unclear: a case series
