After eight months of vibration training, older women did not become stronger, walk better, or improve their balance, even though their thigh muscles declined less than those who did nothing.

What Would Prove This
Per GRADE and EBM methodology, here is what ideal scientific evidence would look like to definitively prove or disprove this claim, ordered from strongest to weakest.
Whether whole-body vibration consistently improves functional outcomes (e.g., gait speed, chair rise, balance) in adults over 75, across diverse populations and protocols.
A systematic review and meta-analysis of all RCTs measuring functional outcomes (Timed Up and Go, 30-second chair stand, gait speed) in adults aged 75+ using whole-body vibration (≥6 months, ≥2x/week), comparing to control groups, with subgroup analysis by baseline function and vibration parameters.
Whether whole-body vibration causes improvement in functional capacity in elderly women when muscle mass is held constant.
A double-blind RCT with 200 women aged 75–85, randomized to vibration vs. sham, with all participants receiving identical resistance training to maintain muscle mass, measuring functional outcomes as primary endpoints over 8 months.
Whether long-term use of whole-body vibration predicts slower decline in functional capacity in older women over time.
A prospective cohort study following 400 women aged 70+ for 5 years, tracking vibration use (frequency, duration) and annual functional assessments (gait speed, SFT), adjusting for baseline strength, comorbidities, and physical activity.
Whether current users of whole-body vibration perform better on functional tests than non-users at a single point in time.
A cross-sectional assessment of 300 women aged 75–85 comparing functional test scores (Timed Up and Go, handgrip) between those currently using vibration (≥6 months) and matched non-users, controlling for age, BMI, and mobility.
Whether isolated cases of functional improvement occur after vibration training in very elderly women.
A case series of 10–20 elderly women with severe sarcopenia and functional decline who began whole-body vibration, documenting changes in mobility and strength over 6–12 months with detailed clinical notes.
