Whole-body vibration impedes the deterioration of postural control in patients with multiple sclerosis
https://www.ncbi.nlm.nih.gov/pubmed/30991299

Abstract
OBJECTIVE:
The current study aimed to investigate if whole-body vibration (WBV) might attenuate the processing functional and neuromuscular degeneration of postural control in patients with MS.
DESIGN:
Performance in postural control was assessed before and after 6 weeks of a control (CON) and a WBV intervention period.
SETTING:
Laboratory at the University of Freiburg & home-based training PARTICIPANTS: Out of 29 interested participants, 15 subjects with severe MS fit inclusion criteria.
MAIN OUTCOME MEASURES:
Centre of pressure displacement (COP), muscle activity and co-contraction indices of m. soleus (SOL), gastrocnemius medialis (GM), tibialis anterior (TA), biceps (BF) and rectus femoris (RF) as well as SOL H/M-ratios.
RESULTS:
After CON, COP was significantly enhanced with reduced muscle activity in RF and diminished shank muscle co-contraction. After WBV, no changes were observed in COP and neuromuscular control. However, over time, TA activity was reduced, but with no changes in muscle activation of SOL, GM and BF or H/M-ratios.
CONCLUSIONS:
After CON, MS patients experienced substantial deteriorations in postural control which have previously been associated with greater postural instability. No further disease-associated deteriorations were observed following the intervention. Thus, WBV might alleviate neurodegeneration of postural control in people with MS.

Whole body vibration improves core muscle strength and endurance in ambulant individuals with multiple sclerosis: A randomized clinical trial
https://www.ncbi.nlm.nih.gov/pubmed/31071658

Abstract
BACKGROUND:
People with Multiple sclerosis (MS) have been found to impair strength and endurance of core muscles compared with healthy people. Whole body vibration (WBV) is a relatively new method of neuromuscular training which can induce positive effects on mobility and postural control of MS patients.
OBJECTIVE:
To evaluate the effects of a 6-week WBV training program on the strength and endurance of core muscles in patients with MS.
METHODS:
Fifty patients were allocated to two groups, one receiving WBV training (intervention) and one no treatment (control). The endurance of core muscles were evaluated using Sorensen, flexion, and side bridge endurance tests. The strength of core muscles was evaluated using a dynamometer. We used the quality of life-54 questionnaire (MSQOL-54) to evaluate patients` quality of life aspects at baseline and two months after the end of study.
RESULTS:
Forty six patients completed the study (mean age: 37.9 ± 7.7; BMI: 23.8 ± 4.3). All outcome measures including strength and endurance of core muscles as well as MSQOL-54 scores significantly improved in WBV group in comparison to control group. While the within-group comparison showed significant improvement in the WBV group (P < 0.001), in the control group, some outcomes measures including physical and mental components of MSQOL-54 deteriorated (P < 0.001) over the course of study.
CONCLUSIONS:
Our study shows that strength and endurance of core muscles as well as quality of life of MS patients can be positively influenced by a 6-week WBV training. The program was well-tolerated by patients and no adverse event was observed.

Study results like the above are very questionable. They did not compare it to an alternative core strength exercise such as planking. Testing against nothing? really?

That's great if you can do a plank. Some of us can't.

Oh, pharmas regularly test against nothing, i.e., placebo.

Placebo is far from nothing. Placebo is where they actually give you "something", its simply that you do not know its really nothing. It's at the core of blinded placebo trials. I have never herd of open label placebo trials. Which you are implying.

My point is that they didn't compare vibration therapy to any other physical activity. Even standing and rocking side to side, or kneeling and rocking or whatever. Nothing. Standing on the spot for the same amount of time as standing on a vibration platform, would of been the obvious min comparison to me.

I don't think there's enough detail in the abstract to determine what the control group was asked to do. We don't know if they were standing, sitting or laying down.

Effects of low vs. high frequency local vibration on mild-moderate muscle spasticity: Ultrasonographical and functional evaluation in patients with multiple sclerosis
https://pubmed.ncbi.nlm.nih.gov/33836458/

Abstract

Background: Local vibration (LV) is a physiotherapy application that aims to reduce spasticity. The study aimed to compare the effects of 50 Hz vs. 100 Hz LV on mild-moderate spasticity, functional performance and muscle architecture.

Methods: Thirty-three patients were randomly divided into three groups: 50 Hz LV group, 100 Hz LV group and the control group. Physical therapy was applied for one hour a day, three days a week, for a total of eight weeks. LV was applied to the right and left medial gastrocnemius muscles for five minutes. Clinical (spasticity, ankle joint position sense, balance, gait) and ultrasonographic (gastrocnemius fascicle length and pennation angle) measurements were performed before and after treatment.

Results: The study was completed with 27 patients. The decrease in spasticity and the increase in fascicle length were found to be statistically significant in the 50 Hz group (both p<0.05). Ankle joint position sense, single-leg stance time, limits of stability/postural sway range in the medio-lateral direction significantly improved in the vibration treatment groups (all p<0.05). The antero-posterior limits of stability and postural sway showed significant improvement in all groups (all p<0.05). While the 50 Hz group showed significant improvement for all walking parameters; velocity, step length and base of support values improved in the 100 Hz group (all p<0.05). The exercise group showed significant improvement only for single support and stance phase percentages of the gait cycle (both p<0.05). According to between group comparisons, significant difference was found only in medio-lateral limits of stabillity (p<0.05). Medio-lateral limits of stabillity scores were better for the 50 Hz group than the 100 Hz and exercise group.
