Changes in elementary finger-hand functions over time in preschool children with spastic cerebral palsy

To examine the development of basic finger-hand motor capacity in a one-year follow-up experiment performed on young children with bilateral spastic cerebral palsy (CP). The maximal finger grip strength (FGMAX), the frequencies of the fastest voluntary isometric finger force changes (FGCHANGE) while holding an object, in addition to the finger (FTAP) and hand tapping frequencies (HTAP) were examined on two separate occasions in 30 children between the ages of three to six years with bilateral spastic CP (BCSP). The examinations were per-formed 12 months apart in order to test for improvements in the aforementioned functions. After a one-year period of time, the FGMAX, FGCHANGE and FTAP values increased by 10-15% in both hands (changes in FTAP values were not statistically significant), while the HTAP values remained unchanged. In regard to the normative samples obtained from children of this age period, the gap in the motor capacity of the fingers did not increase. We observed an improvement in the basic finger functions over a one-year period of time in preschool aged children diagnosed with spastic CP. Interestingly, the improvement proceeded at a similar rate to that observed in normally developing children. However, the fastest hand tapping movements (HTAP) did not improve during this one-year time interval. In addition, we observed that in young children with BSCP, there appears to be considerable potential for the development and reorganisation of the elementary finger functions that are requisite for object manipulation.
