Some 4 years ago, I revisited a therapy advocated by Dr. Cheney back in 1998 in a post on the Bounce Back Chair. Today, a similar item crossed my email: “Whole Body Vibration-Induced Omental Macrophage Polarization and Fecal Microbiome Modification in a Murine Model” 
The key aspect is that it results in modification of the microbiome.
Oh to be a mouse..
It is well known that many many studies dealing with mice do not replicate with humans. Some do. My take-away from the above is simple:
- Vibration appear to help the microbiome,
- The vibration may well trigger exercise like responses from the microbiome.
If we run with this hypothesis, then all of the following may be beneficial:
- Walking in place or other light activity causing bounce
- Skipping rope (if you still have coordination)
- Rebounder Chair
- Whole body vibrator
- Massaging chair
From the study: 20 min/day for 7 days per week for 4 weeks
