Abstract
Background: High Velocity Thrust (HVT) is a technique commonly used by manual therapy practitioners for the treatment of musculoskeletal problems in the U.K. (Fryer et al, 2010). Despite the positive clinical effects for HVT that have now been demonstrated, the curious fact remains that the theoretical basis underpinning every aspect of its use is still underdeveloped (Evans, 2010). Objective: To appraise the evidence provided by studies of synovial joints during HVT using A) passive recording or B) medical imaging techniques. Methods: Systematic keyword searches of relevant on-line databases and journals. The retrieved articles to be evaluated using best practice guidelines for systematic reviews, adapted to suit narrative reviews. Results: 17 selected papers were reviewed. There was a great variety in methodological quality with the papers most relevant to the stated task having the poorest quality. Conclusion: The audible release associated with HVT has a characteristic frequency curve associated with it and occurs around the moment of joint separation. Furthermore, audible release and gaseous cavitation are not always correlated and the relationship between them remains unclear. Overall, a poor quantity and quality of papers in the subject area has led to subjectivity in the analysed results and the reliability of the conclusions drawn is decreased.
