Effect of whole body vibration training on quadriceps muscle strength in individuals with knee osteoarthritis: a systematic review and meta-analysis.
Several studies have reported the effects of whole body vibration (WBV) training on muscle strength. This systematic review investigates the current evidence regarding the effects of WBV training on quadriceps muscle strength in individuals with knee osteoarthritis (OA). We searched PubMed, CINAHL, Embase, Scopus, PEDro, and Science citation index for research articles published prior to March 2015 using the keywords whole body vibration, vibration training, strength and vibratory exercise in combination with the Medical Subject Heading 'Osteoarthritis knee'. This meta-analysis was limited to randomized controlled trials published in the English language. The quality of the selected studies was assessed by two independent evaluators using the PEDro scale and criteriaBut the real secret sauce is Cabcharge's ability to get state taxi regulators to do its bidding at the expense of just about everyone else. In normal markets, a company that fails its customers faces growing competition, forcing it to either improve or die. Not here. Peter Ableson of the University of Sydney claimed in a 2009 paper that between 1990 and 2008, the number of Sydney taxi licences grew by just 20-25 per cent whilst demand for taxis almost doubled. The result is the world's fourth most expensive cab fares. The regulators, in restricting cab licences, have been feathering Cabcharge's nest by keeping supply down and prices up. Way back in 1999 The Productivity Commission said it was "unable to identify benefits to the community that justify
