Vibration and stroke rehab

Two different whole body vibration tests came to different conclusions

Long-Term Effects of 6-Week Whole-Body Vibration on Balance Recovery and Activities of Daily Living in the Postacute Phase of Stroke
Conclusions— Daily sessions of whole-body vibration during 6 weeks are not more effective in terms of recovery of balance and activities of daily living than the same amount of exercise therapy on music in the postacute phase of stroke.

These results suggest that one session of whole body vibration can quickly increase voluntary force and muscle activation of the quadriceps muscle affected by a stroke. One session of whole body vibration (20 Hz frequency, 5mm amplitude) was shown to quickly increase isometric and eccentric strength of knee extensors at the affected side. Whole body vibration may help to increase the effectiveness of an additional functional rehabilitation program.

And this article on the use of it in the gym wonders about its effectiveness.Gimmick or Not, Vibrating Platforms Have Joined the Gym
But maybe it’s not so silly, exercise physiologists say. Although they don’t really know why vibrations should work, researchers report that they actually seem to slightly improve performance in the few minutes after a person gets off the machine.
The problem, though, is that there is little consensus on how fast the vibrations should be or in what direction platforms are supposed to vibrate. Some studies have failed to show any effects from vibrations. And then there is the question of what exactly vibrations are doing to muscles and nerves.
“It certainly is intriguing, and a large portion of the evidence would support that something is happening,” said Lee E. Brown, director of the Center for Sports Performance at California State University, Fullerton. But he added, “We are still trying to figure out exactly what the mechanism is.”

I know the first one failed but I think that if you are trying to get back proprioception this might be useful. I looked for gyms around here having this but no luck.
Four other possibilities:
1. Body Blades - I bought these but in order to get the vibration you need to be able to rapidly move your arm back and forth in a small arc. I currently only have gross movement so this didn't work.
2. Shake Weights - I tried this at a retailer and it has the same problems as the body blade.
3. Dynaflex Sports Pro Plus Gyro Wrist Exerciser - I bought this but it really does require two good hands to get the internal gyroscope spinning. For me I was looking for it to get proprioception going and the intrinsics of the hand.
4. Palm hand sanders. The random orbital kind. Mine is currently broken but I'll try it as soon as I get it fixed.

Remember, this is not something you should try without talking to your doctors.
