Clinical assessment of ankle joint dorsiflexion: a review of measurement techniques.
Ankle dorsiflexion measurement is important for clinical and research use. With so much evidence on the unreliability of goniometric measurements, a systematic review was performed to investigate various alternative techniques for measuring ankle dorsiflexion in the nonneurologic patient. All of the major databases were queried electronically to identify studies that used any method of ankle dorsiflexion measurement in the nonneurologic subject. Keywords included ankle dorsiflexion NOT cerebral palsy NOT stroke, the latter to exclude neurologic conditions. In 755 studies that used some form of ankle joint dorsiflexion measurement, ten different techniques were identified that included various apparatuses designed specifically for this purpose. Reliability testing of these techniques involved test-retest trials with small student populations as subjects, which returned high intraclass correlation coefficient scores. However, their methodological quality would have benefitted from the use of an actual patient population and comparison with a reference standard. When validating ankle dorsiflexion measurement techniques, actual patient populations should be used, otherwise papers would score poorly on methodological quality assessment. Standardizing patient position, foot posture, amount of moment applied, and reference landmarks will ensure that various trial results can be compared directly.
