The effect of proprioceptive neuromuscular facilitation on functional skills, muscle strength, and trunk control in children with cerebral palsy: A randomized controlled trial.

ABSTRACT

BACKGROUND: Proprioceptive neuromuscular facilitation (PNF) is generally used for the lower limbs in children with Cerebral Palsy (CP). This study aimed to determine the effect of PNF and Neurodevelopmental Therapy (NDT) on functional abilities, muscle strength, and trunk control in children with CP. METHODS: Thirty spastic CP children classified as either level I-II in the Gross Motor Function Classification System (GMFCS) or level I-II in the Manual Ability Classification System (MACS) were included. The PNF (n = 15) and the NDT group (n = 15) had physiotherapy for six weeks. The ABILHAND-Kids scale, the Purdue Pegboard Test (PBPT), the Nine-Hole Peg Test (9-HPT), and the Jebson-Taylor Hand Function Test (JTHFT) were employed. Pinch meters, Jamar handheld dynamometers, and digital muscular strength assessments were used. RESULTS: The PNF group increased shoulder flexion (p < 0.05), adduction (p < 0.05), elevation (p < 0.05), scapular abduction (p < 0.05), elbow extension (right) (p < 0.05), grip (p < 0.05), and pinch strengths (left p < 0.05, right p < 0.05). The PNF group had significantly lower 9-HPT (p < 0.05), JTHFT (card turning), JTHFT (simulated feeding), JTHFT (lifting light cans), and JTHFT (lifting weight cans) durations (p < 0.05), and significantly higher PBPT (right-left) PBPT (bimanual), PBPT (assembly). (p < 0.05), ABILHAND (p < 0.05), and TCMS total scores (p < 0.001). While JTHFT (simulated feeding-left), JTHFT (stacking checkers-left), JTHFT (lifting light cans-left), and JTHFT (lifting weight cans-right/left) (p < 0.05) durations decreased in the NDT group, PBPT (right) (p < 0.05) had an increase in duration. CONCLUSION: PNF improves trunk control, upper extremity functional skills, selective proximal muscle strength, and distal upper extremity muscle and grip strength.
