Dance/movement therapy (DMT) represents a powerful multimodal intervention for individuals with Corticobasal Syndrome (CBS) and Progressive Supranuclear Palsy (PSP). Unlike conventional physical therapy, DMT integrates rhythmic movement, emotional awareness, creative expression, and social interaction within a therapeutic framework facilitated by certified dance/movement therapists (BC-DMT). This approach is particularly relevant for CBS/PSP patients given the complex motor and cognitive symptom profiles that these disorders present [@shanahan2015][@hackney2009].
The therapeutic value of DMT for CBS/PSP extends beyond traditional motor rehabilitation. The combination of music, rhythm, and intentional movement engages multiple neural circuits simultaneously—including basal ganglia, cerebellar, motor cortex, and limbic pathways—making it particularly well-suited for addressing the heterogeneous manifestations of 4R-tauopathies.
CBS and PSP present distinct motor challenges that DMT can address through targeted movement interventions:
Corticobasal Syndrome (CBS) Motor Features:
- Asymmetric rigidity and dystonia affecting limb use
- Apraxia (loss of learned motor movements)
- Alien limb phenomenon (involuntary limb movements)
- Myoclonus (involuntary muscle jerks)
- Gait dysfunction and balance impairment
Progressive Supranuclear Palsy (PSP) Motor Features:
- Vertical supranuclear gaze palsy (vertical gaze restriction)
- Postural instability and frequent falls
- Axial rigidity (neck and trunk stiffness)
- Akinesia/bradykinesia (slowness of movement)
- Dysarthria (speech difficulty)
Dance/movement therapy provides a unique advantage by:
- Rhythmic cueing - External rhythmic stimuli bypass basal ganglia dysfunction, improving gait initiation and fluidity
- Movement vocabulary expansion - Creative movement patterns can bypass damaged motor programs affected by cortical-basal degeneration
- Balance training through dynamic movement - Dance's multi-directional movements improve postural stability more effectively than linear exercises
- Non-verbal self-expression - Provides emotional outlet when verbal communication becomes impaired
¶ Cognitive and Neuropsychiatric Benefits
DMT also addresses non-motor symptoms prevalent in CBS/PSP:
- Depression and anxiety - Movement-based emotional expression activates limbic pathways and reduces mood symptoms
- Social isolation - Group dance sessions reduce feelings of loneliness and improve quality of life
- Cognitive stimulation - Learning choreographed sequences challenges executive function and working memory
- Self-efficacy - Mastering new movements builds confidence and sense of agency
Laban Movement Analysis (LMA) is a comprehensive system for describing, visualizing, and interpreting human movement. Developed by Rudolf Laban, it provides a systematic framework essential for tailoring DMT interventions to CBS/PSP symptom profiles.
| Component |
Description |
CBS/PSP Application |
| Body |
What parts move and how they relate |
Focus on unaffected limbs, bilateral integration |
| Effort |
How movement is performed (time, weight, space, flow) |
Adapt effort qualities to patient capabilities |
| Shape |
How the body changes shape |
Use shaping movements to improve body awareness |
| Space |
Where movement occurs (pathways, directions) |
Directional changes improve spatial orientation |
The four effort factors can be modified to match patient abilities:
-
Time (Sudden/Sustained)
- Sudden: Quick reactions for fall prevention training
- Sustained: Slow, controlled movements for rigidity management
-
Weight (Light/Strong)
- Light: Gentle movements for those with significant weakness
- Strong: Resistance training elements for strength preservation
-
Space (Indirect/Direct)
- Indirect: Exploratory movements for spatial disorientation
- Direct: Focused, purposeful movements for targeted rehabilitation
-
Flow (Free/Bound)
- Free: Release unwanted muscle tension
- Bound: Control involuntary movements (myoclonus, dystonia)
Bartenieff Fundamentals builds on LMA with movement patterns that support functional daily living:
| Pattern |

CBS/PSP Benefit |
| Breathing |
Core connection |
Reduces axial rigidity, improves relaxation |
| Weight shift |
Weight transfer |
Fall prevention, gait training |
| Pelvic shift |
Core stability |
Improves sitting balance, reduces falls |
| Leg/foot patterns |
Walking |
Gait normalization, stepping strategies |
| Arm reach |
Upper extremity |
Maintains reaching function, counteracts apraxia |
| Head movement |
Gaze control |
Addresses vertical gaze palsy adaptations |
Choreographic approaches in DMT for CBS/PSP differ from traditional dance in several important ways:
- Adaptability - Movements are continuously modified based on daily symptom fluctuation
- Safety prioritization - All movements designed to minimize fall risk
- Patient-directed - Emphasis on patient's creative choices within therapeutic framework
- Residual function focus - Maximizing use of preserved motor abilities

For CBS (asymmetric presentation):
- Focus on bilateral movement integration
- Use less-affected limb to guide affected limb
- Mirror exercises to engage mirror neuron systems
- Weight-bearing exercises on less-affected side
For PSP (axial involvement):
- Seated dance options for balance safety
- Vertical gaze compensatory strategies (visual cueing)
- Neck rotation exercises within dance context
- Fall recovery choreography
Dance/movement therapy promotes neuroplasticity through multiple biological pathways:
- BDNF (Brain-Derived Neurotrophic Factor): Rhythmic movement stimulates BDNF release, promoting neuronal survival and synaptic plasticity in basal ganglia and motor cortex
- GDNF (Glial Cell Line-Derived Neurotrophic Factor): Animal studies suggest dance may enhance GDNF expression in nigrostriatal pathways

Dance uniquely engages multiple sensory systems simultaneously:
- Auditory - Music rhythm, beat perception
- Visual - Choreography observation, spatial awareness
- Proprioceptive - Body position awareness
- Vestibular - Balance and spatial orientation
- Tactile - Partner contact, floor awareness
This multisensory engagement promotes cortical reorganization and adaptive neuroplasticity.
fMRI studies in Parkinson's disease patients participating in dance have shown:
- Increased connectivity in motor networks
- Enhanced cerebellar-cortical communication
- Improved basal ganglia function during externally-cued movements
- Reduced hyperactivation in compensatory motor areas
