The human brain holds the key to unlocking human potential, and occupational therapists are the locksmiths.
In 1989, a groundbreaking lecture delivered to occupational therapy professionals would change the course of the profession forever. Dr. Susan D. Farber's Eleanor Clarke Slagle lecture, titled "Neuroscience and Occupational Therapy: Vital Connections," proposed a revolutionary idea: that in-depth knowledge of the neurosciences serves as a common denominator that enhances our ability to interpret all aspects of human behavior1 .
More than three decades later, this connection has evolved from a hypothesis to a fundamental principle that informs cutting-edge therapeutic practices. This article explores how the marriage between neuroscience and occupational therapy has transformed rehabilitation, offering new hope for clients recovering from brain injuries, managing neurodegenerative conditions, or seeking to improve cognitive function throughout their lives.
Understanding neural mechanisms allows for more targeted and effective interventions.
Neuroscience principles help tailor therapy to individual brain characteristics and needs.
Neuroplasticity represents one of the most significant neuroscientific discoveries for therapeutic practice. Contrary to the long-held belief that the brain's structure was largely fixed after childhood, we now understand that the brain possesses a remarkable capacity to reorganize itself by forming new neural connections throughout life2 .
This physiological process allows the brain to compensate for injury and disease and to adjust its activities in response to new situations or environmental changes. After an injury such as a stroke or traumatic brain injury, the brain naturally attempts to reroute functions around damaged areas through synaptic remodeling, where neurons build new dendrites and enhance synaptic strength2 .
Occupational therapists leverage this innate capacity by designing targeted therapeutic activities that promote meaningful, repeated practice of specific tasks. The goal extends beyond restoring motor function to addressing cognitive, emotional, and executive domains—highlighting the interconnectedness of different brain areas2 .
The brain's ability to reorganize itself forms the foundation for recovery after neurological injury.

Another critical concept bridging neuroscience and occupational therapy is cognitive reserve—the brain's ability to withstand damage and age-related decline by using alternative neural networks or strategies2 . Unlike structural reserve (determined by brain size or gray matter volume), cognitive reserve is shaped by life experiences and can be strengthened throughout our lives.
Occupational therapy practitioners collect information on a client's educational background, lifestyle, career, and social habits to gauge their cognitive reserve capacity. This assessment helps predict recovery potential and guides intervention design.
A client with extensive social involvement and a history of mentally demanding activities typically responds more robustly to therapy, often demonstrating faster skill reacquisition and improved functional outcomes2 .
Traditional rehabilitation often focused on isolated skills—working on motor function separately from cognitive training. Modern neuroscience-informed practice recognizes that this approach fails to mimic real-world demands, where people must simultaneously manage cognitive, emotional, and motor tasks2 .
Dual-tasking integrates multiple demands into therapeutic activities, creating richer neural activation and stronger rehabilitation outcomes. This approach fosters neuroplasticity by reinforcing existing networks and creating new ones, enhancing overall functional performance2 .
Consider a client recovering from a stroke that affected the orbitofrontal cortex—a region critical for emotional regulation, impulse control, and social behavior2 . While traditional motor rehabilitation would address movement deficits, a neuroscience-informed occupational therapist takes a more comprehensive approach:
Engaging the client in social conversation while performing motor tasks to stimulate emotional regulation pathways.
Incorporating decision-making, sequencing, and impulse control activities alongside motor exercises.
Introducing novel, complex tasks in a structured, supportive setting to enhance dendritic growth and synaptic remodeling2 .
This multidimensional approach facilitates recovery not just at the functional level but at the neural level, demonstrating the power of combining occupational therapy with neuroscience.

| Cognitive Reserve | Brain's resilience to damage through alternative neural networks | Leveraging client's life experiences to predict recovery potential and customize interventions |
| Dual-Tasking | Simultaneously performing cognitive and motor tasks | Mimicking real-world demands to create richer neural activation and functional recovery |
| Synaptic Remodeling | Process where neurons build new dendrites and enhance connections | Using meaningful, purposeful activities to drive structural changes in the brain |
| Cortical Mapping | Identification of functional areas of the cerebral cortex | Precise targeting of interventions to activate specific brain regions during therapy |
Despite the growing integration of neuroscience into occupational therapy practice, research supporting specific interventions has historically been limited. A comprehensive review of occupational therapy research in neurological disorders revealed that of 116 articles published in a leading journal over a one-year period, only 21 (18%) addressed neurological rehabilitation3 .
Among these, the diversity of conditions studied was remarkably narrow. Of the effectiveness and efficacy research published during this period, 8 of 10 studies focused on stroke, with only 1 each addressing multiple sclerosis and traumatic brain injury. Conditions such as Parkinson's disease, spinal cord injury, Huntington's disease, and amyotrophic lateral sclerosis were not represented3 .

Several studies have examined the effectiveness of various interventions for stroke recovery. The methodologies and outcome measures used in these studies reflect the growing sophistication of therapy research:
| Study Focus | Intervention Approach | Outcome Measures | Key Findings |
|---|---|---|---|
| Computer-Based Rhythm Training 3 | Computer-based timing intervention with metronome; 60 min × 3 days/wk for 4 weeks | Upper Extremity Fugl-Meyer Assessment (FMA), Arm Motor Ability Test (AMAT), Canadian Occupational Performance Measure (COPM) | Some improvement seen in all outcome measures for both participants with chronic, severe, stroke-induced hemiparesis |
| Modified Constraint-Induced Therapy (mCIT) 3 | mCIT group wore a mitt and practiced functional activities with affected arm for 6 hr/day for 10 days | Wolf Motor Function Test (WMFT), COPM | Both mCIT and bilateral therapy groups improved performance with no significant differences between approaches |
| Functional Training with Electrical Stimulation 3 | Electrical stimulation while wearing brace followed by repetitive task-specific training; 45-60 min sessions 2 days/wk for 5 weeks | Modified Ashworth Scale (spasticity), FMA, Box and Block test, AMAT | Reduction in finger spasticity with slight improvement in functional measures |
Occupational therapists integrating neuroscience into their practice rely on various assessment tools and intervention approaches to evaluate progress and guide treatment:
| Tool/Measure | Purpose | Population | What It Assesses |
|---|---|---|---|
| Fugl-Meyer Assessment (FMA) | Measure motor recovery, balance, sensation, and joint function | Stroke | Sensorimotor impairment following stroke through comprehensive tasks |
| Canadian Occupational Performance Measure (COPM) | Identify, measure, and prioritize self-perceived performance and satisfaction in daily activities | Various neurological conditions | Client's self-assessment of occupational performance and satisfaction over time |
| Wolf Motor Function Test (WMFT) | Assess upper extremity motor ability through timed and functional tasks | Stroke | Motor function using timed tasks and functional ability rating scale |
| Modified Ashworth Scale | Measure muscle spasticity through resistance to passive movement | Conditions with spasticity (stroke, TBI, SCI) | Degree of muscle tone and spasticity by moving joints through range of motion |
| Sensory Profile | Assess behavioral responses to sensory events in daily life | Various neurological conditions | Sensory processing patterns across four categories: seeking, avoiding, sensitivity, and registration |
As we look ahead, the integration of neuroscience into occupational therapy continues to evolve. The profession faces both opportunities and challenges in fulfilling what the American Occupational Therapy Association has termed its Centennial Vision—to become a "powerful, widely recognized, science-driven, and evidence-based profession"3 .
To achieve the Centennial Vision, the field must improve both the volume and diversity of research in neurological rehabilitation. This includes expanding beyond the current focus on stroke to encompass the full spectrum of neurological conditions that occupational therapists encounter in practice3 .
Furthermore, there is a critical need to modify academic and clinical practice to enable occupational therapists to spend more time producing high-quality evidence supporting the crucial role they play in neurological rehabilitation3 .
The vital connections between neuroscience and occupational therapy first articulated in Farber's 1989 lecture have only grown stronger with time. What began as a hypothesis has matured into a sophisticated partnership that continues to transform how we approach rehabilitation and recovery.
"By understanding the mechanisms of neuroplasticity, cognitive reserve, and neural reorganization, occupational therapists can design interventions that work with the brain's innate capacities for change."
This knowledge enables practitioners to not only address the physical manifestations of neurological conditions but also the cognitive, emotional, and psychological dimensions that are equally central to human occupation and identity5 6 .
As we deepen our understanding of the brain's remarkable capabilities, the potential for occupational therapy to enhance recovery, build resilience, and transform lives after neurological injury or disease has never been greater. The vital connections between these fields continue to illuminate new pathways to participation, engagement, and meaning in daily life.
