Effect of upper extremity constraints on functional and dynamic postural control in children with hemiplegic cerebral palsy.

PURPOSE

To compare the effects of upper extremity constraints on functional and dynamic postural control in children with hemiplegic cerebral palsy.

MATERIALS AND METHODS

Twelve children with hemiplegic cerebral palsy and 12 typically developing children ages 5 to 12 years (GMFCS I-II) were evaluated with the Timed Up and Go (TUG) and Biodex Balance System during three upper extremity (UE) conditions: 1) Free UEs (no constraints), 2) Simple UE constraint (unaffected/dominant UE constrained with a sling), and 3) Difficult UE constraint (Simple constraint plus the other UE holding cup of water).

RESULTS

The UE condition had significant effects on Overall Stability Index (OSI) (F = 24.899, < .001), Medial-Lateral Stability Index (MLSI) (F = 4.380, = .018), Anterior-Posterior Stability Index (F = 6.187, = .004), and TUG scores (F = 113.372, < .001). Group was significant for OSI (F = 7.906, = .010), MLSI (F = 13.113, = .002), and TUG (F = 36.282, < .001).

CONCLUSIONS

The upper extremity appears to have a role in maintaining functional balance and postural stability in children with hemiplegic cerebral palsy and should be considered during intervention programs.
