REHABILITATION METHODS FOR MOTOR DEFICITS:
 
Major theories of rehabilitation training


Traditional Therapy:

Traditional therapeutic exercise program consists of positioning, ROM exercises, strengthening, mobilization, compensatory techniques, endurance training (e.g., aerobics).
Traditional approaches for improving motor control and coordination: emphasize need of repetition of specific movements for learning, the importance of sensation to the control of movement, and the need to develop basic movements and postures. (Kirsteins, Black, Schaffer, and Harvey, 1999)

Proprioceptive (or peripheral) Neuromuscular Facilitation (PNF) (Knott and Voss, 1968)
Uses spiral and diagonal components of movement rather than the traditional movements in cardinal planes of motion with the goal of facilitating movement patterns that will have more functional relevance than the traditional technique of strengthening individual group muscles
Theory of spiral and diagonal movement patterns arose from observation that the body will use muscle groups synergistically related (e.g., extensors vs. flexors) when performing a maximal physical activity
Stimulation of nerve/muscle/sensory receptors to evoke responses through manual stimuli to increase ease of movement-promotion function
It uses resistance during the spiral and diagonal movement patterns with the goal of facilitating irradiation of impulses to other parts of the body associated with the primary movement (through increased membrane potentials of surrounding alpha motoneurons, rendering them more excitable to additional stimuli and thus affecting the weaker components of a given part)
Mass-movement patterns keep Beevors axiom: Brain knows nothing of individual muscle action but only movement

Bobath approach / neurodevelopmental technique (NDT) (Bobath, 1978)
The goal of NDT is to normalize tone, to inhibit primitive patterns of movement, and to facilitate automatic, voluntary reactions and subsequent normal movement patterns.
Based on the concept that pathologic movement patterns (limb synergies and primitive reflexes) must not be used for training because continuous use of the pathologic pathways may make it too readily available to use at expense of the normal pathways
Probably the most commonly used approach
Suppress abnormal muscle patterns before normal patterns introduced
Mass synergies avoided, although they may strengthen weak, unresponsive muscles, because these reinforce abnormally increased tonic reflexes, spasticity
Abnormal patterns modified at proximal key points of control (e.g., shoulder and pelvic girdle)
Opposite to Brunnstrom approach (which encourages the use of abnormal movements); see the following

Brunstrom approach/Movement therapy (Brunnstrom, 1970)
Uses primitive synergistic patterns in training in attempting to improve motor control through central facilitation
Based on concept that damaged CNS regressed to phylogenetically older patterns of movements (limb synergies and primitive reflexes); thus, synergies, primitive reflexes, and other abnormal movements are considered normal processes of recovery before normal patterns of movements are attained
Patients are taught to use and voluntarily control the motor patterns available to them at a particular point during their recovery process (e.g., limb synergies)
Enhances specific synergies through use of cutaneous/proprioceptive stimuli, central facilitation using Twitchells recovery
Opposite to Bobath (which inhibits abnormal patterns of movement)

Sensorimotor approach/Rood approach (Noll, Bender, and Nelson, 1996)
Modification of muscle tone and voluntary motor activity using cutaneous sensorimotor stimulation
Facilitatory or inhibitory inputs through the use of sensorimotor stimuli, including, quick stretch, icing, fast brushing, slow stroking, tendon tapping, vibration, and joint compression to promote contraction of proximal muscles

Motor relearning program/Carr and Shepard approach (Carr et al., 1985)
Based on cognitive motor relearning theory and influenced by Bobaths approach
Goal is for the patient to relearn how to move functionally and how to problem solve during attempts at new tasks
Instead of emphasizing repetitive performance of a specific movement for improving skill, it teaches general strategies for solving motor problems.
Emphasizes functional training of specific tasks, such as standing and walking, and carryover of those tasks

Behavioral approaches (Noll, Bender, and Nelson, 1996) include:
Kinesthetic or positional biofeedback and forced-use exercises
Electromyographic biofeedback EMGBF: makes patient aware of muscle activity or lack of it by using external representation (e.g., auditory or visual cues) of internal activity as a way to assist in the modification of voluntary control
In addition to trying to modify autonomic function, EMGBF also attempts to modify pain and motor disturbances by using volitional control and auditory, visual, and sensory clues
Electrodes placed over agonists/antagonists for facilitation/inhibition
Accurate sensory information reaches brain through systems unaffected by brain → via visual and auditory for proprioception
