"Neurodevelopmental treatment (NDT) is a hands-on treatment approach that was developed to enhance the function of adults and children who have difficulty controlling movement as a result of neurological deficit. It was developed with the understanding that patients with brain injuries have a limited repertoire of movement patterns. During treatment interventions, repeated experience in movement ensures that a particular pattern is readily accessible for motor performance. The more a patient performs certain movements, the easier these movements becomes. Without NDT interventions, the patient likely will develop a limited set of movement patterns that he or she will apply to nearly all tasks. NDT should begin before such generalized movement synergies become hard-wired in the patient's brain. To achieve these objectives, therapists employ numerous techniques, including handling techniques, weight bearing over the affected limb and use of bilateral movement to normalize the movement". - Kennedy Krieger Institute

"PNF is philosophy of intervention used to address the client factors of posture, mobility, strength, effort and coordination based on mass movement patterns that are diagonal in nature and that resemble movement seen in functional activities. Major emphasis in this approach is on the developmental sequencing of movement and the balanced interplay between agonist and antagonist in producing voluntary movement" - Pedretti
