Brief description of study.

The purpose of this study is to understand how sensory perception and movement control work together to keep your hand movements accurate. We hope this information may be useful one day to improve rehabilitation techniques in patients with brain lesions.

Eligibility of study

You may be eligible for this study if you meet the following criteria:

  • Conditions: Right Handed
  • Age: 18 years - 45 years
  • Gender: All

Inclusion Criteria: 

Potential subjects must be between the ages of 18-45 years old and right-handed. Aging has been shown to affect the morphology of sensory and motor nerves, conduction velocities of nerves, and number of motor neurons in the spinal cord; to avoid these confounding factors we will only examine younger-to middle-aged adults.  There are differences in cortical function and corticospinal projections such that testing the right arm of a right-handed individual is not necessarily equivalent to testing the left arm of a left-handed individual.  To eliminate this confound, we will only test right-handed individuals.

Exclusion Criteria: 

Potential subjects will be excluded if they have any past or present history of seizure, stroke, any brain or peripheral nerve disease, severe head trauma, or spinal cord surgery. We will also exclude individuals who have learning or attention conditions such as ADHD. In addition people who either have orthopedic or pain conditions, or a history of seriously injured bones, joints or muscles in either arm, may not participate.  We will also exclude subjects who do not have normal or corrected-to-normal vision, as they may perform the behavioral task differently if they can’t see the reaching targets very well, which would be a confound.

This study investigates how sensory perception and movement control work together to ensure accurate hand movements. Sensory perception refers to how we feel things through touch, while movement control is how our brain and muscles work together to move our body parts. This research aims to learn more about these processes.

Participants will undergo tests to observe their sensory perception and movement control. The study will focus on the right hand of right-handed individuals to maintain consistency in results. Participants will perform tasks that require reaching for targets, which will help researchers understand the coordination between sensory input and motor output.

  • Who can participate: This study is open to right-handed individuals aged 18 to 45 years. Participants must have normal or corrected-to-normal vision and no history of neurological or orthopedic conditions, including seizure, stroke, brain or peripheral nerve disease, severe head trauma, spinal cord surgery, learning or attention conditions like ADHD, and history of seriously injured bones, joints, or muscles.
  • Study details: Participants will perform tasks that test their hand movement accuracy. The study focuses on the right hand to ensure consistent results.
