7.4 Physical Rehabilitation and Neurogenic Communication Disorders
Key Takeaways
- In post-stroke rehabilitation, Musical Neglect Training (MNT) targets unilateral spatial neglect by positioning acoustic instruments across the neglected hemispace to stimulate visual scanning and contralateral motor reaching.
- Traumatic Brain Injury (TBI) rehabilitation is structured according to the Rancho Los Amigos Levels: Levels I-III focus on low-intensity sensory stimulation; Levels IV-VI require low-stimulus, highly structured containment; Levels VII-VIII target complex executive functioning.
- Spinal Cord Injury (SCI) music therapy focuses on respiratory vital capacity and vocal intonation training, requiring acute vigilance for Autonomic Dysreflexia in lesions at or above T6.
- Parkinson's Disease interventions utilize Therapeutic Singing aligned with LSVT LOUD principles, Vocal Intonation Therapy (VIT), and Rhythmic Speech Cueing to overcome hypophonia, vocal fold bowing, and speech festination.
- In Amyotrophic Lateral Sclerosis (ALS), music therapy transitions across degenerative stages: from early non-fatiguing vocal maintenance and voice banking to middle-stage assistive technology (Soundbeam/eye-gaze MIDI) and late-stage comfort care.
Physical Rehabilitation and Neurogenic Communication Disorders
Physical rehabilitation and neurogenic communication disorders require music therapists to operate within interdisciplinary neuro-rehabilitation teams (alongside physical therapists, occupational therapists, speech-language pathologists, and physiatrists). Interventions harness neuroplastic reorganization, sensorimotor entrainment, and auditory-motor coupling across acute post-injury stabilization, inpatient rehabilitation facilities (IRF), outpatient therapy, and progressive neurodegenerative disease management.
1. Stroke (Cerebrovascular Accident - CVA) Rehabilitation
Stroke results in focal neurological deficits secondary to ischemic infarction or intracerebral hemorrhage. Beyond primary sensorimotor hemiparesis and aphasia (addressed via NMT techniques), stroke frequently impairs visuospatial processing, emotional regulation, and midline spatial orientation.

| MUSICAL NEGLECT TRAINING (MNT) PROTOCOL |
+=========================================================================================================+
| PATHOPHYSIOLOGY: Right Parietal Lobe Stroke ──► Left Unilateral Spatial Neglect (Hemispatial Inattention)|
| Patient fails to attend, respond, or orient to sensory stimuli in the contralateral left visual field. |
| │ |
| ▼ |
| MNT CLINICAL MECHANISM: |
| 1. Spatial Instrument Placement: Diatonic metallophones, tone bars, or drum arrays are positioned |
| horizontally spanning from the intact right hemispace deep across the midline into the left hemispace.|
| 2. Active Melodic Scanning: The therapist plays an ascending musical scale starting on the right and |
| leading toward the left, prompting the client to follow the auditory trajectory with eyes and head. |
| 3. Contralateral Motor Reaching: The client is prompted to strike tone bars sequentially from right to |
| left, crossing the sagittal midline to reach the neglected left extremity. |

2. Traumatic Brain Injury (TBI) & Rancho Los Amigos Levels
TBI occurs when external mechanical forces cause diffuse axonal injury (DAI), focal contusions, and secondary hypoxic/ischemic damage. Cognitive and behavioral recovery follows a predictable hierarchy standardized by the Rancho Los Amigos Levels of Cognitive Functioning (RLCF).

| TBI RANCHO LOS AMIGOS CLINICAL STAGING MATRIX |
+===================================+=====================================================================+
| Rancho Los Amigos Level | Clinical Presentation & Targeted Music Therapy Protocols |
+===================================+=====================================================================+
| LEVELS I, II, III | - Presentation: Coma, Vegetative State (UWS), Minimally Conscious |
| (No Response, Generalized | State (MCS). Inconsistent or absent responses to external stimuli.|
| Response, Localized Response) | - Protocol: Musical Sensory Stimulation. Short sessions (10–15 min).|
| | Present salient, personally familiar music (family voices, favorite|
| | songs) at low volume to elicit localized responses (eye tracking, |
| | heart rate deceleration, localized motor movement). |
+-----------------------------------+---------------------------------------------------------------------+
| LEVELS IV, V, VI | - Presentation: Confused-Agitated (IV), Confused-Inappropriate (V), |
| (Confused-Agitated, | Confused-Appropriate (VI). Highly agitated, brief attention span, |

| | - Protocol: Executive Functioning & Community Reintegration. |
| | Multi-step therapeutic songwriting, multi-part ensemble drumming, |
| | cognitive dual-tasking, vocational planning, and identity grief. |
+-----------------------------------+---------------------------------------------------------------------+
3. Spinal Cord Injury (SCI)
Spinal cord injury results in motor and sensory impairment below the neurological level of injury (tetraplegia/quadriplegia in cervical lesions C1–C8; paraplegia in thoracic/lumbar lesions T1–L5).
Clinical Focus Areas in SCI Rehabilitation
- Respiratory Vital Capacity Rehabilitation: High cervical and thoracic injuries paralyze intercostal and abdominal musculature, resulting in restrictive pulmonary deficits, reduced Forced Vital Capacity (FVC), diminished peak expiratory flow, and weak cough. Music therapists implement Therapeutic Singing, Vocal Intonation Therapy (VIT), and Wind Instrument Playing (harmonica, recorder) to train diaphragmatic recruitment, increase subglottic pressure, and enhance airway clearance.
- Critical Safety: Autonomic Dysreflexia (AD):
- Medical Emergency: Occurs in patients with lesions at or above T6. Triggered by noxious stimuli below the level of injury (e.g., full bladder/kinked catheter, bowel impaction, skin pressure, tight mallet straps/constrictive clothing).
- Clinical Signs: Sudden, life-threatening spike in blood pressure (hypertension >20–40 mmHg above baseline), severe pounding headache, bradycardia, profuse diaphoresis and flushing above the lesion, and cold/pale skin below the lesion.
- Immediate Therapist Protocol: Immediately sit the patient fully upright (to pool blood in lower extremities), loosen all tight clothing, straps, or adaptive cuffs, check catheter/foley for kinks, and summon emergency nursing/physician staff immediately. Never lie the patient supine.

Amyotrophic Lateral Sclerosis (ALS) Degenerative Staging Continuum
Because ALS is a relentlessly progressive disease with intact cognitive awareness, music therapy must dynamically adapt across three stages:
- Early Stage (Diagnostic to Mild Dysarthria/Paresis): Focus on non-fatiguing vocal maintenance, diaphragmatic breathing support, and emotional coping with existential loss. Voice Banking & Legacy Audio: Recording the client singing, speaking, and conveying personal messages before bulbar degeneration causes complete loss of speech.
- Middle Stage (Moderate/Severe Quadriplegia & Dysarthria): Transitioning to Accessible Music Technology (AMT): Utilizing ultrasonic motion sensors (Soundbeam), eye-gaze communication devices linked to MIDI instruments, and adaptive switch controllers to allow creative expression and autonomy despite loss of limb movement.
- Late / End Stage (Anarthria, Ventilator Dependence, Total Quadriplegia): Transitioning to receptive music therapy, music-assisted relaxation, family legacy projects (heartbeat recordings), and bedside palliative comfort care.
A music therapist is working in an inpatient physical rehabilitation unit with a 24-year-old client who sustained a complete C6 spinal cord injury. During a Therapeutic Instrumental Music Performance (TIMP) session using adaptive universal cuff mallets, the client suddenly complains of a severe, pounding headache. The therapist observes profound facial flushing and sweating above the neck, while telemetry reveals a dramatic blood pressure spike to 190/110 mmHg and bradycardia at 48 bpm. What is the therapist's immediate clinical action?
A music therapist is assigned to work with a 19-year-old patient with severe traumatic brain injury who is currently functioning at Rancho Los Amigos Level IV (Confused-Agitated). The patient exhibits severe restlessness, yelling, combativeness, and a 1-minute attention span. Which environment and intervention structure should the therapist utilize?
A 62-year-old patient recovering from a right middle cerebral artery stroke presents with severe left-sided unilateral spatial neglect. The patient consistently ignores food on the left side of the tray and fails to orient to people standing on their left side. How should the music therapist structure a Musical Neglect Training (MNT) intervention to rehabilitate spatial attention?
A client with Amyotrophic Lateral Sclerosis (ALS) is transitioning from the middle stage (moderate dysarthria, severe upper extremity quadriparesis) toward the late stage. The client expresses intense grief over losing the ability to play the acoustic guitar and speak clearly with family. Which clinical music therapy adaptation is most indicated at this stage of disease progression?
