Spasticity-Adapted Treatment

When to Apply This Modification

Spasticity is a UMN phenomenon. It occurs when descending inhibitory pathways from the cortex or brainstem are damaged, releasing the spinal reflex arc from normal modulation. The following conditions produce spasticity:

• Stroke — conditions/stroke: Contralateral spasticity develops days to weeks after the acute event. Typically affects the flexors of the upper extremity (arm drawn into flexion) and extensors of the lower extremity (leg held in extension). Pattern: flexor synergy arm, extensor synergy leg.
• Multiple sclerosis — conditions/multiple-sclerosis: Spasticity fluctuates with relapses and remissions. May affect any limb. Often bilateral. Severity varies widely — from mild stiffness to severe contracture.
• Cerebral palsy — conditions/cerebral-palsy: Spasticity present from birth or early childhood. Distribution depends on type: spastic diplegia (legs), spastic hemiplegia (one side), spastic quadriplegia (all limbs). Chronic spasticity often leads to fixed contractures.
• Traumatic brain injury — conditions/traumatic-brain-injury: Spasticity develops during recovery; pattern depends on injury location and severity.
• Spinal cord injury (incomplete, above level) — conditions/spinal-cord-injury: UMN signs (spasticity, hyperreflexia, clonus) below the level of an incomplete injury. Complete SCI may produce spasticity below the level due to loss of descending inhibition on intact spinal circuits.
• ALS — conditions/als: Mixed UMN and LMN disease. Spasticity coexists with muscle wasting and weakness — a uniquely challenging presentation.

Key distinction: Spasticity (UMN) is velocity-dependent — the faster you stretch the muscle, the stronger the resistance. This is fundamentally different from rigidity (e.g., Parkinson's — conditions/parkinsons-disease), which is velocity-independent (constant resistance regardless of speed). The distinction matters because the treatment approach differs: spasticity requires slow movement; rigidity does not have the same velocity trigger.

What Standard Principles Change

This modification alters the rate, rhythm, and technique selection parameters from techniques/principles-of-massage, and changes how several standard techniques are applied:

Rate and Rhythm Must Be Slow and Predictable

• Standard treatment allows variable rate and rhythm depending on therapeutic intent (slow for relaxation, fast for stimulation).
• Spasticity-adapted treatment requires slow, predictable movement at all times. Rapid movements trigger the stretch reflex — the faster the stretch, the stronger the spastic catch. Even transitioning between techniques must be slow.

Technique Selection Is Restricted

• Contraindicated techniques:
• Tapotement / percussion — rapid striking activates the stretch reflex
• Quick passive stretching — velocity-dependent resistance makes this counterproductive and potentially painful
• Rapid petrissage or wringing — the lift-and-squeeze cycle can trigger spastic catch if performed too quickly
• Coarse vibration applied rapidly
• Preferred techniques:
• Slow effleurage — parasympathetic activation, does not trigger velocity-dependent reflex
• Rocking and shaking — slow, rhythmic oscillation reduces tone (see techniques/rocking-and-shaking)
• Sustained compression — prolonged holds at trigger points or hypertonic areas
• Static contact and holding — parasympathetic; reduces sympathetic drive that worsens spasticity
• Slow, sustained fascial work — engages viscoelastic creep without triggering the stretch reflex
• Muscle approximation — pushing origin and insertion toward each other reduces spindle firing (see techniques/muscle-approximation)

General → Specific → General — Elongated Warming Phase

• The warming phase (general techniques) should be longer than standard — spastic muscles require more time to reduce their baseline tone before specific work is safe. A standard 2-minute warm-up for a 10-minute treatment may need to be 3-4 minutes.
• The return to general work at the end is also extended, providing a prolonged calming transition.

Superficial → Deep → Superficial — Slower Depth Progression

• Progress through layers more slowly than standard. Each increase in depth must be gradual enough to avoid triggering a spastic response. If the muscle catches (sudden increase in resistance), the therapist has moved too fast — reduce depth, slow down, wait for the muscle to release, then cautiously progress again.

Clinical Rationale

The Velocity-Dependent Mechanism

Spasticity is mediated by the stretch reflex arc: 1. Muscle spindles in the muscle belly detect stretch rate and length. 2. In a normal nervous system, descending cortical and brainstem pathways (reticulospinal, corticospinal) modulate spindle sensitivity and dampen excessive reflex responses. 3. When UMN pathways are damaged, this modulation is lost. The spindles become hyperexcitable — they fire at lower stretch thresholds and with greater intensity. 4. The result: any quick stretch of the muscle produces an exaggerated contraction (spastic catch). The faster the stretch, the stronger the response. This is the definition of velocity dependence. Implication for massage: Any technique that quickly changes muscle length activates the stretch reflex in a spastic muscle. The muscle contracts forcefully against the therapist's hands, which is painful for the client, counterproductive therapeutically, and potentially injurious if the therapist tries to force through the resistance.

Why Slow Techniques Work

• Below-threshold stimulus: When a stretch or compression is applied slowly, the rate of length change stays below the spindle firing threshold. The muscle does not catch.
• Sustained holds engage GTO inhibition: Golgi tendon organs respond to sustained load by triggering autogenic inhibition — the muscle relaxes. This pathway is intact in most UMN conditions and can be used to reduce tone.
• Rhythmic oscillation reduces tone: Slow, rhythmic rocking or shaking provides repetitive low-amplitude input that gradually reduces spindle firing rate. The effect is cumulative — after 2-3 minutes of gentle rocking, the muscle's resting tone often decreases measurably.
• Muscle approximation reduces spindle firing: Pushing origin and insertion toward each other shortens the muscle, which unloads the spindles and reduces their firing rate. This is an immediate tone-reduction technique.

Working WITH Tone, Not Against It

Attempting to force a spastic muscle into length (aggressive stretching, vigorous petrissage against the resistance) produces:

• Increased spasticity (the muscle fights harder)
• Pain
• Potential muscle or tendon damage
• Client distrust and anxiety, which further increases tone via sympathetic activation

The correct approach is to reduce the tone first using inhibitory techniques, then gently explore the available range.

Modified Treatment Protocol

Phase 1: Tone Reduction (5-8 minutes in a 30-minute session)

1. Positioning for inhibitory patterns:

• Stroke (hemiplegic arm): Position the arm in extension, external rotation, supination, and wrist/finger extension — the opposite of the flexor synergy pattern. Use pillows and towel rolls. Do not force the position — go to wherever the arm rests comfortably, then work toward the inhibitory pattern as tone decreases.
• Stroke (hemiplegic leg): Position in slight flexion at hip and knee — the opposite of the extensor synergy pattern.
• CP, MS, TBI: Position varies by individual spasticity pattern. The general principle is to position AWAY from the dominant spastic pattern without forcing.

2. Rocking and rhythmic techniques: Begin with slow, gentle rocking of the trunk or limb (see techniques/rocking-and-shaking). Rhythm should be approximately 1 oscillation per 2-3 seconds. Continue for 2-3 minutes. Monitor for tone reduction — the limb should begin to feel heavier and less resistant. 3. Static contact and slow effleurage: Apply warm, still hands to the spastic muscle group for 30-60 seconds (static contact — see techniques/static-contact). Follow with slow effleurage along the muscle, centripetal direction, rate of approximately 1 stroke per 5-6 seconds. This is much slower than standard effleurage. 4. Muscle approximation: For accessible muscles, gently push origin and insertion toward each other. Hold for 10-15 seconds. Release slowly. This unloads the spindles and provides immediate but temporary tone reduction.

Phase 2: Specific Work (8-12 minutes)

5. Sustained compression on hypertonic areas: Once tone is reduced, apply sustained compression to trigger points or areas of maximum hypertonicity. Hold for 60-90 seconds with steady, non-increasing pressure. Do NOT pulse or oscillate the pressure rapidly. 6. Slow petrissage: If tone permits, apply slow kneading — significantly slower than standard (approximately 1 cycle per 3-4 seconds instead of 1 per second). Monitor continuously for spastic catch. If the muscle resists, stop, wait, return to rocking, then try again. 7. Gentle fascial work: Sustained holds for viscoelastic creep. Apply and wait — do not push through resistance. Let the tissue release on its own timeline. 8. Slow passive ROM (not stretching): Move the joint slowly through whatever range is available WITHOUT resistance. This is passive range of motion, not stretching. The moment you feel resistance increase, stop and hold at that position. Do not push past the spastic catch.

Phase 3: Integration and Closing (5-8 minutes)

9. Return to rocking and slow effleurage. Re-establish the relaxation state achieved in Phase 1. 10. Position the client in a comfortable, supported inhibitory posture. Ensure all limbs are bolstered. 11. Self-care guidance: Gentle self-stretching (SLOW), positioning strategies at home, and avoidance of triggers (cold, anxiety, sudden movements all worsen spasticity).

Parameters

Safety Considerations

• Clonus alert. If a quick movement triggers clonus (rhythmic involuntary oscillation at a joint, typically the ankle), stop the triggering technique immediately. Maintain the joint in a neutral position and wait for the clonus to subside. Do not attempt to stretch through clonus. Document the episode.
• Contracture vs. spasticity. Chronic spasticity can lead to fixed contracture (structural shortening of muscle and connective tissue). A contracted muscle will not release regardless of technique — it is structurally shortened, not just neurologically overactive. Do not force range of motion against a contracture. The distinction: spasticity reduces with sustained holds and positioning; contracture does not.
• Heterotopic ossification. In SCI and TBI, bone can form in soft tissue around joints (heterotopic ossification). Aggressive ROM or deep work in these areas can worsen the condition or cause fracture. If ROM feels blocked by a hard endpoint (bone-on-bone feeling where it should not exist), do not force further.
• Medication interactions. Many clients with spasticity take baclofen, tizanidine, dantrolene, or botulinum toxin injections. These medications reduce tone pharmacologically. After a botulinum injection (onset 3-7 days), the muscle may be unusually flaccid for 3-4 months. Adjust treatment — the muscle that was spastic last month may now be hypotonic.
• Autonomic dysreflexia in SCI. Same risk as in techniques/sensation-modified-treatment. Noxious stimuli below the level of injury in SCI above T6 can trigger a hypertensive crisis. Spastic catch itself can be the noxious stimulus. Avoid triggering spasticity.
• Fatigue. Neurological clients fatigue faster than the general population. Spasticity itself is exhausting — the muscles are working constantly against the client's will. Shorter sessions are often more effective (see techniques/reduced-duration-modifications).
• Do not fight the tone. If a spastic muscle resists, the therapist should never push harder. This escalates the reflex cycle and risks injury to the client and the therapist.

CMTO/OSCE Relevance

• Technique speed is visibly assessed. On an OSCE station involving a neurological condition with spasticity, the examiner watches the therapist's speed of movement. Standard-speed techniques on a spastic limb demonstrate a failure to adapt treatment to the client's neurological status.
• Rocking as a tone-reduction strategy is expected. The use of rhythmic oscillation (rocking, slow shaking) before specific work demonstrates understanding of the velocity-dependent mechanism and appropriate use of inhibitory techniques.
• Positioning for inhibitory patterns is a scoreable element. Placing the hemiplegic arm in extension and external rotation (rather than leaving it in the flexor synergy pattern) demonstrates understanding of spasticity management.
• Common exam error: Performing rapid petrissage or tapotement on the affected side of a stroke client. This demonstrates a fundamental misunderstanding of UMN spasticity and is a safety error.
• Written exam: Be able to distinguish spasticity (velocity-dependent, UMN) from rigidity (velocity-independent, basal ganglia) and explain why the treatment approach differs.
