Validity and reliability of a novel 3D ultrasound approach to assess static lengths and the lengthening behavior of the gastrocnemius medialis muscle and the Achilles tendon in vivo

1

A novel 3D ultrasound approach was developed to measure the lengths of the gastrocnemius medialis muscle and Achilles tendon in vivo.
2

The study aimed to evaluate the validity and reliability of this 3D ultrasound method compared to MRI for muscle-tendon length measurements.
3

Participants provided informed consent, and the study was approved by the Ethics Committee of the University of Graz, Austria.
4

Reliability analyses were conducted to assess intra-rater and inter-rater reliability based on ultrasound data collected in two sessions.
5

The study found that the proposed 3D ultrasound approach demonstrated adequate accuracy and high reliability for measuring muscle-tendon lengths.
