Holding Hands

We connect and communicate with other people through affective, or social, touch. Affective touch helps us form emotional and social bonds. Our lab aims to restore affective touch to people with disabilities.

Affective Touch

People with high-level tetraplegia often lose the ability to move and feel all four limbs. We use intracortical microstimulation in somatosensory cortex and below-injury peripheral nerve stimulation to provide sensory feedback to participants using brain-controlled functional electrical stimulation to regain voluntary control of reaching and grasp.

We connect and communicate with other people through affective, or developing strategies to restore proprioception to people with upper limb loss via peripheral nerve stimulation. Our research also investigates the neural coding of proprioceptive information and the integration of proprioception with prosthesis control.


We conduct studies to explore how users of neurotechnology feel about their devices and to understand the experience of participating in neurotechnology research.

Typing with Prosthetic Hand

In the Graczyk Lab, we believe that our job is done successfully only when we actively foster trainees' scientific development, help facilitate their career goals, and support their well-being.


We value diversity and believe that bringing more voices to the table is critical to advance our research to improve healthcare for all.

Land Acknowledgement

In recognizing the land upon which we reside, we express our gratitude and appreciation to those who lived and worked here before us; those whose stewardship and resilient spirit makes our residence possible on this traditional homeland of the Lenape (Delaware), Shawnee, Wyandot Miami, Ottawa, Potawatomi, and other Great Lakes tribes (Chippewa, Kickapoo, Wea, Piankishaw, and Kaskaskia). We also acknowledge the thousands of Native Americans who now call Northeast Ohio home.


Case Western Reserve University and the greater Cleveland area occupy land officially ceded by 1100 chiefs and warriors signing the Treaty of Greenville in 1795.
