Learning Objectives At the end of the lecture, the students should be able to: Discuss the theoretical basis of the sensorimotor approaches Identify the traditional sensorimotor approaches to therapeutic exercise Discuss the reconstruction of the sensorimotor approaches Differentiate and discuss the sensorimotor approaches to therapeutic exercise in terms of: Proponents Principles Techniques/procedures Components
3
What are the sensorimotor approaches?
Brunnstrom’s movement therapy Neurodevelopmental approach Rood approach Proprioceptive neuromuscular facilitation
4
Theoretical Basis Reflex and Hierarchical Theory
The basic unit of motor control are reflexes Reflexes purposeful movement Damage to the CNS results to re-emergence of and inability to control the reflexes Motor control is hierarchically arranged CNS structures involved with movement can be grouped into HIGHER, MIDDLE, and LOWER levels Higher centers regulate and control the middle and lower centers Damage to the CNS results to disruption of the normal coordinated function of these levels

Rood Techniques Margaret Rood
6
Premise Motor patterns are developed from fundamental patterns/reflexes which are refined and controlled as an individual matures Sensory stimulation is applied to muscles and joints normalize tone produce desired movement Sensorimotor control is developmental Movement should be purposeful Repetition of sensorimotor responses is necessary
7
Principles of treatment
Tonic neck and labyrinthine reflexes can assist or retard the effects of sensorimotor stimulation Stimulation of specific receptors to produce response Rules on sensory input A fast, brief stimulus produces a large synchronous movement A fast, repetitive stimulus produces a maintained response Slow, rhythmical, repetitive sensory input deactivates the body
8
Principles of treatment
Muscles have different duties Heavy work muscles: stabilizers Maintenance of posture Light work muscles: mobilizers Skilled movement, repetitive or rhythmical patterns of distal musculature Heavy work muscles should be integrated before light work muscles
9
Four components of motor control
Reciprocal inhibition Aka innervation, mobility Phasic or quick type of movement Contraction of the agonist while antagonist relaxes Serves a protective function Cocontraction Aka coinnervation, stability Tonic or static type of movement Simultaneous contraction of the agonist and antagonist Foundation for postural control
10
Four components of motor control
Heavy work Aka mobility superimposed on stability Proximal muscles contract and move while distal segments are fixed Skill Aka mobility and stability Proximal segments are stabilized while distal segments move
11

Proprioceptive Neuromuscular Facilitation
Dr. Herman Kabat Maggie Knott Dorothy Voss
15
Premise Brain knows nothing of individual muscle action, rather, total movement patterns Extremity patterns of movement are rotational and diagonal in nature Normal motor development proceeds in a cephalo-caudal and proximo-distal direction Early motor behavior is dominated by reflex activity; Mature motor behavior is supported by postural reflexes
16
Principles of treatment
All human beings have untapped movement potential Improvement in motor ability is dependent upon motor learning Frequency of stimulation and repetition of activity promotes retention of motor learning and develops strength and endurance Activities are goal-directed with techniques of facilitation, mainly proprioceptive, are utilized to hasten learning
17
Diagonal patterns Mass movement patterns observed in most functional activities Head, neck, trunk Flexion with rotation to the right or left Extension with rotation to the right or left Extremities Three components Flexion/extension Abduction/adduction External/internal rotation Reference points UE: shoulder joint LE: hip joint

22
Bilateral patterns Combined upper extremity or lower extremity diagonal patterns Symmetrical Asymmetrical Reciprocal
23
Bilateral patterns Symmetrical
Paired extremities (either UE of LE) perform the same diagonal pattern and direction Promotoes trunk flexion and extension
24
Bilateral patterns Asymmetrical
Paired extremities perform opposite diagonal pattern but same direction Facilitates trunk rotation
25
Bilateral patterns Reciprocal
Paired extremities move in opposite diagonal pattern and direction Promotes head, neck, and trunk stability
26
Combined movements of UE/LE
Combined upper extremity and lower extremity movements Ipsilateral Contralateral Diagonal reciprocal
27
Combined Movements of UE/LE
Ipsilateral Extremities of the same side (UE and LE) move in the same diagonal pattern and direction
28
Combined Movements of UE/LE
Contralateral Aka alternating reciprocal pattern Extremities of the opposite sides move in the same diagonal pattern and direction
29
Combined Movements of UE/LE
Diagonal reciprocal Contralateral extremities moving in the same diagonal patterns and directions while opposite contralateral extremities move in the opposite diagonal pattern and direction
30
Basic procedures Manual contacts Communication/commands Stretch
Traction Approximation Maximal resistance Timing
31
Manual contacts Placement of the therapist’s hand on the patient
Used to provide pressure and tactile stimulation to muscles Pressure should be applied opposite to the direction of the desired motion Guide direction of movement Utilized by the patient as in “self-touching” during chopping and lifting movements
32
Communication/commands
effective use of volume and tone of voice can be facilitatory or inhibitory (use in moderation to not avoid adaptation) preparatory commands need to be clear and concise action commands should be accurate, short, and timed provide visual cues, demonstration of movement tailor your motivation strategies; know your patient (developmental and cognitive level)
33
Stretch part to be moved must be placed in the extreme lengthened range of the pattern; all parts being considered; tension should be felt in all muscle components apply stretch reflex manually by quickly taking the stretched part beyond point of tension then instructing the patient to perform the desired motion
34
Traction separating joint surfaces stimulate the proprioceptive centers promote movement used during pulling motions
35
Approximation compressing joint surfaces stimulate the proprioceptive centers promote stability or maintenance of posture as well as postural reflexes ensure proper alignment of the joint structures
36
Maximal resistance maximum amount of resistance that can be applied without breaking the patient’s hold (Voss, et al., 1985) principle of irradiation/overflow weaker muscles are reinforced or strengthened by resisted contraction of the stronger muscle components increases strength
37
Timing Refers to the sequence of muscle contraction that occurs during activity Normal timing (PNF) Distal segments move first followed by proximal segemts Rotation occurs throughout the pattern Timing for emphasis Superimposing maximal resistance upon patterns of facilitation in order that overflow or irradiation occurs
38
Techniques and strategies
Reversal of antagonists Combination of isotonics Resisted progression Dynamic reversals Stabilizing reversals Rhythmic stabilization Relaxation Techniques Directed to the agonists Contract relax Hold-relax Repeated contractions Replication Rhythmic rotation Rhythmic initiation
39
Reversal of antagonists
Dynamic Reversals Aka Slow reversals Isotonic contractions of agonist isotonic contraction of antagonist Contraction of the stronger pattern then progressed to weaker pattern Indications impaired strength and coordination limitation of motion fatigue
40
Reversal of antagonists
Stabilizing Reversals Alternating isotonic contractions of the agonists then antagonists Very limited motion (ROM) allowed Indications Impaired strength Impaired stability and balance Impaired coordination
41
Reversal of antagonists
Rhythmic Stabilization Alternating isometric contractions of the agonist then antagonist No motion is allowed Indications Impaired strength Impaired coordination Limitation of motion Impaired stabilization control and balance
42
Techniques directed to the agonist
Repeated contractions Repeated isotonic contractions from the lengthened range (induced by quick stretch and enhanced by resistance) Performed throughout the range or part of the range at a point of weakness Indications Impaired strength Impaired initiation of movement Fatigue and LOM
43
Techniques directed to the agonist
Rhythmic Initiation Aka Rhythm Technique voluntary relaxation passive movement active-assisted movement repeated isotonic contraction of major muscle components of the pattern (gradually increasing as patient responds) active motion Indications Inability to relax Hypertonicity Difficulty initiating movement Motor planning and motor learning deficits Deficits in communication
44
Techniques directed to the agonist
Combination of Isotonics Aka Agonist Reversal Resisted concentric contraction of agonist muscles moving through the range stabilizing contraction (holding) eccentric lengthening contraction (moving slowly back to starting position) No relaxation between contractions Indications Weak postural muscles Inability to eccentrically control body weight during transitions Poor dynamic postural control
45
Techniques directed to the agonist
Resisted Progression Stretch, approximation, and tracking resistance applied manually to facilitate pelvic motion and progression during movement Indications Impaired timing and control of lower trunk/pelvic segments during movement Impaired endurance
46
Relaxation Techniques
Contract-Relax Performed at a point of LOM Strong, small range isotonic contraction of the antagonist isometric contraction (hold: 5 to 8 seconds) voluntary relaxation passive movement into new range of the agonist pattern Contract-relax-active contraction: same as contract relax but active movement into the new range Indication Limitation of motion
47
Relaxation Techniques
Hold-relax Performed in a position of comfort and below level of pain Isometric contraction of the antagonist voluntary relaxation passive movement into the new range Hold-relax-active contraction: same as hold-relax but movement into new range is active Indication Limitation I PROM with pain
48
Relaxation Techniques
Rhythmic Rotation Slow, repetitive rotation of a limb at a point where LOM is noted Limb is slowly moved into new range as muscles relax Repeated whenever tension is felt Indication Relaxation of excess tension in muscles (hypertonia) combined with PROM of the range-limiting muscles
