Deans' stroke musings: The arm movement detection (AMD) test: A fast robotic test of proprioceptive acuity in the arm

Changing stroke rehab and research worldwide now.Time is Brain! trillions and trillions of neurons that DIE each day because there are NO effective hyperacute therapies besides tPA(only 12% effective). I have 523 posts on hyperacute therapy, enough for researchers to spend decades proving them out. These are my personal ideas and blog on stroke rehabilitation and stroke research. Do not attempt any of these without checking with your medical provider. Unless you join me in agitating, when you need these therapies they won't be there.

What this blog is for:

My blog is not to help survivors recover, it is to have the 10 million yearly stroke survivors light fires underneath their doctors, stroke hospitals and stroke researchers to get stroke solved. 100% recovery. The stroke medical world is completely failing at that goal, they don't even have it as a goal. Shortly after getting out of the hospital and getting NO information on the process or protocols of stroke rehabilitation and recovery I started searching on the internet and found that no other survivor received useful information. This is an attempt to cover all stroke rehabilitation information that should be readily available to survivors so they can talk with informed knowledge to their medical staff. It lays out what needs to be done to get stroke survivors closer to 100% recovery. It's quite disgusting that this information is not available from every stroke association and doctors group.

The arm movement detection (AMD) test: A fast robotic test of proprioceptive acuity in the arm

My proprioception is decreased quite a bit. Fairly useless, describes a problem but gives no solution.

Abstract: Study examined the validity and reliability of a short robotic test of upper-limb proprioception, the Arm Movement Detection (AMD) test, for evaluating the impact of sensory deficits on impairments of motor control, motor adaptation, and functional recovery in stroke survivors. Thirty-nine participants completed the AMD test: 25 neurologically intact control participants (NIC), 7 survivors of stroke with intact proprioception in the more-affected limb (HSS+P), and 7 survivors of stroke with impaired or absent proprioception in the more-affected limb (HSS-P). Subjects grasped the handle of a horizontal planar robot, with their arm and the robot hidden from view. The robot applied graded force perturbations, which produced small displacements of the handle. The AMD test required subjects to respond verbally to queries regarding whether or not they detected arm motions. Each participant completed ten, 60-second trials; in five of the trials, force perturbations were increased in small increments until the participant detected motion while in the others, perturbations were decreased until the participant could no longer detect motion. The mean and standard deviation of the 10 movement detection thresholds were used to compute a Proprioceptive Acuity Score (PAS), which quantifies the likelihood that proprioception is intact. Lower PAS scores correspond to higher proprioceptive acuity. Significant group differences were found, with the NIC and HSS+P groups having lower (i.e., better) PAS scores than the HSS-P group. A subset of the participants completed the AMD test multiple times and the AMD test was found to be reliable across repetitions. The AMD test required less than 15 minutes to complete and provided an objective, ratio-scaled measure of proprioceptive acuity in the upper limb.
