Whole-body vibration (WBV) involves oscillation of the plates to produce vibrations. It cause: rapid eccentric-concentric muscle action to enhance muscle performance due to rapid reflex and stretch-reflexes. WBV can also cause temporary positive changes to soft tissues like skeletal muscle by increasing circulation. Dry needling (DN) is an invasive skilled intervention performed by licensed physical therapists requiring a thin filiform needle through the skin to reach soft tissues like muscle or bone that causes a mild inflammatory response to improve pain and relax muscles tissue. Analysis of jump height was the outcome measure used to determine muscle performance. The purpose of our study is to compare WBV and DN in regard to improving jump performance in the healthy and injured adult populations.
