Slackline Training in Children with Spastic Cerebral Palsy: A Randomized Clinical Trial.

OBJECTIVE

To assess whether a slackline intervention program improves postural control in children/adolescents with spastic cerebral palsy (CP).

DESIGN

Randomized controlled trial.

SETTING

Patients' association.

PARTICIPANTS

Twenty-seven children/adolescents with spastic CP (9-16 years) were randomly assigned to a slackline intervention ( = 14, 13 ± 3 years) or control group ( = 13, 12 ± 2 years).

INTERVENTION

Three slackline sessions per week (30 min/session) for 6 weeks.

MAIN OUTCOME MEASURES

The primary outcome was static posturography (center of pressure-CoP-parameters). The secondary outcomes were surface myoelectrical activity of the lower-limb muscles during the posturography test and jump performance (countermovement jump test and Abalakov test). Overall (RPE, >6-20 scale) rating of perceived exertion was recorded at the end of each intervention session.

RESULTS

The intervention was perceived as "very light" (RPE = 7.6 ± 0.6). The intervention yielded significant benefits on static posturography (a significant group by time interaction on Xspeed, = 0.006) and jump performance (a significant group by time interaction on Abalakov test, = 0.015).

CONCLUSIONS

Slackline training improved static postural control and motor skills and was perceived as non-fatiguing in children/adolescents with spastic CP.
