In normal motor development, spinal cord and
brainstem reflexes become modified and their
components rearrange into purposeful movement
through the influence of higher centers.
Proprioceptive and exteroceptive stimuli can be
used to evoke desired motion or tonal changes.
Recovery of voluntary movements post stroke
follows a mass to discrete pattern.
a produced, correct motions must be practiced
to be learned.
Practice within the context of daily activities
enhances the learning process.
Afferent innervation / sensation is necessary for
production of effective movement.

TONIC REFLEXES
e Tonic reflexes are assessed to
determine whether they can be used in
early treatment to initiate movement
when none exists.
e Then, while sitting without back support
and with the involved arm supported as
described before, the patient is pushed
backward and encouraged to regain
upright posture actively.
RETRAINING PROXIMAL UPPER
EXTREMITY CONTROL (STAGES 1-3)
e To move the patient from stage | (flaccidity) to
stage 2 (beginning synergy), the basic limb
synergies are elicited at a reflex level, using
as many reflexes, associated reactions, and
facilitation procedures as are necessary to
elicit a response.
o If the involved scapula elevates as a result of an
associated reaction, resistance is then added on the
involved side as the patient is asked to "hold."
e Contraction of the pectoralis major, a strong
component of the extensor synergy, can be elicited by
the associated reaction in which the therapist
supports the patient's arms in a position between
horizontal abduction and adduction, instructs the
patient to bring his arms together, and resists the
noninvolved arm just proximal to the elbow.
o As contraction occurs bilaterally the patient is
instructed, "Don't let me pull your arms apart." Then
he attempts to bring his arms together voluntarily.
o Bilateral "rowing" is the procedure used to
initiate elbow extension. In the rowing
procedure, movements toward extension
combined with pronation are resisted and
movements into flexion combined with
supination are guided .
o First, elbow extension is elicited as an
associated reaction by resisting the non involved
arm as it moves into extension and assisting the
involved arm into extension toward the non
involved knee.
Once the affected limb is felt to contract,
resistance is offered ‘bilaterally.
e e. g., holding a piece of wood while sawing,
hammering, or painting it; holding a package
steady while opening it, addressing it, or
fastening it; supporting body weight while
polishing or washing large surfaces such as a
table or floor.

ENCOURAGING ACTIVE ELBOW
EXTENSION
e To encourage active elbow extension,
once the triceps is activated via -rowing
and weight bearing, unilateral resistance
is offered to the patient's attempts to
move into an extension pattern.
o Bilateral pushing na activities reinforce both
synergies. lroning and polishing are examples of
activities that use the flexor and extensor synergies
alternately and repeatedly.
RETRAINING PROXIMAL UPPER
EXTREMITY CONTROL (STAGES 4-6)
e This motion requires that the strongest
components of each synergy be subdued.
e To assist in getting the hand behind the body, a
swinging motion of the arm combined with trunk
rotation is helpful; if balance is good, this can be
done more easily when standing.
Once the scapula is mobilized, the serratus is activated
in its alternate duty of scapula protraction by placing the
arm in the forward-horizontal position and asking, and
assisting, the patient to reach forward.
It is helpful to rehearse this motion with the patient using
the non-involved extremity.
Quick stretches are applied by pushing backward into
scapular retraction and the patient is asked to hold.
Once activated, a holding contraction of the serratus is
sought.
These procedures continue, moving the arm in
increments toward the arm overhead position.
Once the movement has been achieved, practice with
functional activities reinforces it.
TRAINING SUPINATION AND PRONATION
WITH ELBOW EXTENDED
o Patients who recover comparatively rapidly after a
stroke may spontaneously achieve stage 6; however,
many hemiplegic patients do not achieve full recovery.
e Twitchell (1951) stated that patients who reached
stages 3 and 4 within 10 days after stroke recovered
completely; this has never been verified in the
literature.
o It is easier for the patient to stabilize the wrist in
extension when the elbow is extended; therefore,
training starts with the elbow extended and the
wrist supported by the therapist.
e To move from hand stage 3 (flexion) to hand stage
4 (semi voluntary mass extension) spasticity of the
finger flexors must be relaxed using a series of
manipulations.
tension is seen by some relaxation of the flexed position.
If relaxation is incomplete, further manipulations are done.
With the forearm still supinated, rapid repeated stretch
stimuli are applied to the dorsum of the fingers by rolling
them toward the palm with a rapid stroking motion to
stretch finger extensors.
When flexor tension is relaxed, the forearm is pronated
and the arm elevated above horizontal (Souque's
phenomenon).
Stroking over the dorsum of the fingers and forearm
continues as extension is attempted, but effort exerted
should be minimal to avoid a build-up of tension.
e The other extensor type activities are those
that require the hand to be used fiat, such as
smoothing out a garment while ironing or a
sheet while making the bed.
