PURPOSE: The Askling H-test is a commonly used clinical test to indicate the readiness to return to sport following hamstring injury. Sporting organisations and in particular physiotherapists are now using the test with DorsaVi movement sensor technology to assess whether an athlete is ready to return to sport. Despite its increasing use there is currently no published data indicating the reliability of DorsaVi movement sensors for use in the Asklings H-test. Thus the aim of this study was to identify the reliability of DorsaVi sensor evaluation of the Asklings H-Test in community Australian Rules Football players and to determine normative data ranges using this technology.

METHODS: 29 healthy males were recruited from a local amateur Australian Rules football team. DorsaVi movement sensor technology was used to assess active straight leg range, passive straight leg range and peak velocity of movement using a standardised protocol. 11 participants returned for reliability testing a week after the first session .

RESULTS: participants were 23 (2) yrs old, 179 (7) cm high and weighed 84(10)kg’s. Paired t-tests revealed no significant differences between the two testing sessions (P>0.5). Intra-class correlation co-efficient’s ranged from .75-.98. Active flexibility for the H-test averaged (SD) 103 (12) degrees and was greater than passive flexibility 78(12). There were no significant differences between the right and left legs, with the percentage difference being less than 3%.

CONCLUSIONS: DorsaVi movement sensor technology can be used to provide a simple and reliable objective measure of the Askling’s H-test. Whilst the results concur with previous published data, the clear advantage of the DorsaVi system is its ease of use coupled with immediate reliable results. Further research is required it is possible that the use of the DorsaVi system to assess the Askling’s H-test may assist physiotherapists and other medical staff in making more informed decisions about an athletes readiness to return to sport.
