Reliability of a new computerized equinometer based on Silfverskiöld test to measure gastrocnemius tightness.

This compact equinometer has excellent intra-rater reliability and moderate to good inter-rater reliability. Since this reliability is optimal in the 14-15 N range, this load should be used going forward in clinical practice, especially when aiming to define a pathological threshold for tightness of the gastrocnemius muscles.
