The degree of brain activation in specific motor and sensory areas during imagined movements in stroke patients with hemiparesis is linked to their ability to perform motor imagery. This human factors research insight is drawn from a 2012 study published in ISRN Neurology. Using Neuroimaging (fmri) and self-report questionnaire with 11 participants, researchers explored how this design variable affects real-world outcomes. The key design takeaway: Designers of rehabilitation tools and therapies should consider incorporating motor imagery components and potentially assess a user's imagery ability to personalize the intervention.

Key Findings
- 01Shared neural substrates between motor imagery and motor execution were confirmed in the bilateral premotor cortex, SMA, and contralesional inferior parietal lobule.
- 02A negative correlation was found between kinaesthetic imagery ability and BOLD signal change in primary sensorimotor areas (areas 4p and 3a) during motor imagery, indicating that higher imagery ability was associated with lower activation in these regions.
Application
Design takeaway
Designers of rehabilitation tools and therapies should consider incorporating motor imagery components and potentially assess a user's imagery ability to personalize the intervention.
How to apply
When designing assistive devices or therapeutic software for individuals with motor impairments, consider features that facilitate and measure motor imagery, and adapt the difficulty or type of imagery task based on user performance.
Project actions
- 01When designing a product for users with motor impairments, consider how mental rehearsal or imagery could be incorporated into its use.
- 02Think about how to provide feedback that helps users improve their motor imagery skills.
Method & Evidence
Variables
Strengths & Limitations
Strengths
- +Directly investigates motor imagery in a clinical population (stroke patients).
- +Combines neuroimaging with subjective measures of imagery ability.
Limitations
The study involved a small number of participants with stroke, and the findings might not apply to all types of motor impairments or all individuals.
Reliability & validity
The use of fMRI provides objective measures of brain activity, enhancing reliability. The correlation analysis adds to the validity of the findings regarding imagery ability and neural correlates. However, the small sample size may limit generalizability and statistical power.
Think critically
How might the observed correlation between imagery ability and brain activation influence the design of adaptive rehabilitation technologies for stroke survivors?
Design Principles
"Personalize interventions based on individual cognitive and motor imagery capabilities."
Understanding these neural correlates is crucial for developing more effective rehabilitation strategies. It suggests that interventions targeting motor imagery could be tailored based on an individual's inherent imagery capabilities, potentially leading to more personalized and efficient recovery.
What This Means for Your Design
This study found that when stroke patients imagine moving, their brains activate similarly to when they actually move. People who are better at imagining movements show less brain activity in the main movement areas, suggesting they use these areas more efficiently.

Paragraph starter
Research indicates that motor imagery, the mental rehearsal of movements, engages similar neural pathways to actual motor execution. In stroke patients with hemiparesis, a higher ability in motor imagery has been associated with reduced activation in primary sensorimotor cortices, suggesting a more efficient neural processing. This highlights the potential for designing rehabilitation tools that incorporate and enhance motor imagery to optimize recovery.
