Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
However, therapies to improve proprioceptive function in these populations are either non-existent or very limited in scope although it is established that proprioceptive impairments severely degrade motor function. The proposed protocol focuses on proprioception for fine motor function of the hand/wrist joint complex, because hand/wrist motor control is highly important for activities of daily living.
The specific aims are to determine if a 2-day wrist proprioceptive training:
1. improves limb position sense acuity,
2. improves the spatial precision of wrist/hand motor tasks,
3. increases the efficiency of performing such motor tasks,
4. is associated with neural changes in cortical processing as measured by short-latency somatosensory evoke potentials (SEP) and motor evoked potentials (MEP) using transcranial magnetic stimulation.
The study follows a crossover design with two arms and two groups. Time frame for the completion of the study is up to 7 days depending on the start day of the week (Monday through Friday). No testing will occur on the weekend.
Group 1 will have the following time frame: Day 1: pre-test (approx. 3 hrs.) and training intervention (approx. 30 min.). Day 2: training intervention (approx. 30 min.) and post-test 1 (approx. 3 hrs.). Days 3-6: Usual care (min. of 2 days required). Days 5-7: Post-test 2 (depending on the start day of the week, it is either Day 5,6, or 7).
Group 2 will have the following time frame: Day 1: pre-test 1 (approx. 3 hrs.). Days 2-4: Usual care (min. of 2 days required). Days 4-6: pre-test 2 (approx. 3 hrs.) and training intervention (approx. 30 min.). Days 5-7: Training intervention and post-test 1 (depending on the start day of the week, it is either Day 5,6, or 7).

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Proprioceptive training
This arm will receive specialized robot-aided proprioceptive training of the wrist next to usual care.
Proprioceptive training
Training includes a virtual balance board and center-out task. Small vibratory motors placed on forearms provide vibro-tactile movement feedback (VTF). During familiarization participants learn to associate VTF with wrist movement and visual feedback. Vision is occluded after this phase. In the virtual balance board task participants use wrist motion to roll a ball to a target on the board. VTF indicates the desired movement direction and ball velocity. The center-out task involves wrist motion to control a cursor to reach a target. The wrist robot delivers an assistive force towards the target. VTF signals magnitude and direction of the cursor deviating away from the desired path.
Usual care
This arm will receive what participants have been receiving from their healthcare providers. It may range from no treatment to various sessions of occupational and physical therapy at home, day rehabilitation, or outpatient visits.
Usual care
Usual care refers to care that participants receive through their healthcare providers. It may range from no treatment to various sessions of occupational and physical therapy received at in- or outpatient rehabilitation clinics or at home.
