| Abstract: | Introduction: It is crucial to evaluate all muscle forces around the foot and ankle before a tendon transfer is considered in Charcot-Marie-Tooth (CMT) disease. However, the current method of measuring muscle force by the Medical Research Council scale (MRC-scale) is lacking. Ultrasound may have the potential to objectively determine indicators of muscle force. This research aimed to build a database of ultrasound parameters in healthy subjects, determine the feasibility and reliability of those parameters, compare those parameters to those of subjects with CMT and compare those parameters to the MRC-scale. Methods: 50 healthy subjects, and 6 subjects with CMT, were enrolled. The muscle thickness, cross-sectional area, echo intensity, fascicle length and pennation angle were determined by ultrasound measuring of the gastrocnemius, soleus, tibialis anterior, tibialis posterior, peroneus longus and peroneus brevis. Furthermore, the MRC score was determined for the calf muscles and tibialis anterior. Results: A database of ultrasound parameters for healthy subjects was established. The reliability and feasibility are moderate-good for ultrasound measurements of the muscle thickness, cross-sectional area and echo intensity. The measurement of the fascicle length and pennation angle presents a greater challenge for all the muscles, excluding the gastrocnemius. Our demonstration in a small population indicates that ultrasound is a valid measure to distinguish people with CMT from healthy people based on muscle characteristics. There is no conclusive correlation between the MRC-scale and the ultrasound parameters. Conclusion: Our research showed promising results in the use of ultrasound as a measure to determine muscle characteristics linked to force in people with Charcot-Marie-Tooth disease (CMT). This research combined with future research can lead to objective measures that can aid orthopaedic surgeons in clinical decision-making and predictable results of tendon transfers in neuromuscular disorders. |
