Alghadir AH, et al. – This paper contemplated the effects of local vibration on muscle strength, among healthy adults. It was disclosed that the local vibration utility on the target muscle possibly enhanced the muscle strength in healthy adults. In order to ascertain the findings advanced research was warranted.

Methods

• Data was extracted from PubMed, CINAHL, Scopus and Web of Science, via a combination of the following keywords: Vibration, vibration therapy, power, maximal voluntary contraction, performance, rate of force development and vibratory exercise.
• The Medical Subject Headings ‘vibration’, ‘strength’ and ‘exercise’ were also used.
• The bibliographical search was limited to articles published in English.
• The inclusion studies were those that analyzed the effect of localised vibration on muscle strength in healthy humans.
• 2 independent evaluators verified the quality of the selected studies through the PEDro Scale and the Cochrane Collaboration’s tool, for assessing the risk of bias. Muscle strength was estimated for each intervention.

Results

• An evaluation was done of 29 full-text studies for eligibility.
• 18 studies did not match the inclusion criteria, and were excluded.
• The 11 selected studies reported an average PEDro score of 5.36/10.
• Maximum studies exhibited marked improvements in muscle strength after the application of local vibration.
• A significant change was noted in the vibration training parameters and target muscle location.
