Ages Eligible for Study: | 12 Years to 80 Years (Child, Adult, Older Adult) |
Sexes Eligible for Study: | All |
Accepts Healthy Volunteers: | Yes |
Sampling Method: | Non-Probability Sample |
Inclusion criteria:
- subjects must be between the ages of 12-80
- subjects must be able to give written informed consent or consent by proxy to participate
- subjects with the diagnosis of CP must have a score of 2 or 3 on the Modified Ashworth Scale in at least one of the following in the operating limb: wrist flexors, wrist extensors, elbow flexors, or elbow extensors
- control subjects must have a Modified Ashworth score of 0 for all of the above muscle groups in both upper limbs
- subjects must have the minimal motor ability necessary to participate in the trial. This will be measured as follows: after 3 trials, subjects must be able to complete a basic virtual driving with an average minimum speed of no less than 1.2 m/s, an average trial time of no more than 18 seconds, and an average deviation of the center of the virtual wheelchair of no more than 1.5 m from the path center, for each of the two joysticks used. These values are derived from Americans with Disabilities Act (ADA) standard dimensions and human walking speed.
Exclusion Criteria:
- subjects who are not able to tolerate sitting for 2 hours (the estimated length of the experiment)
- subjects who have active pelvic or thigh wounds (they may be worsened by prolonged sitting)
- subjects with a history of seizures in the last 90 days (uncontrolled seizures may be induced by a computer screen task)
