ABSTRACT

PURPOSE: This study compared the effect of performing gastrocnemius stretching with and without the self-myofascial release of the sole on the active and passive ankle dorsiflexion angles and muscle tone of the gastrocnemius muscle in subjects with short gastrocnemius muscle. METHOD: A total of 23 subjects with short gastrocnemius muscles were included in this study. The study participants were divided into two experimental groups. Group A performed gastrocnemius muscle self-stretching exercises only, while group B performed self-myofascial release of the sole using a massage ball after the gastrocnemius muscle self-stretching exercises. For both groups, the active and passive ankle dorsiflexion angles were measured using a goniometer, and the tone of the gastrocnemius muscle was assessed using the MyotonPRO®. RESULTS: Within-group comparison showed that the participants in both groups A and B had significantly increased active and passive ankle dorsiflexion angles and decreased gastrocnemius muscle tone (p < .05) after performing their respective exercises. However, no significant differences in the said criteria were observed between groups A and B (p>.05). CONCLUSION: The results of this study showed that both methods were effective in increasing active and passive dorsiflexion angles and decreasing muscle tone. Thus, it is recommended to tailor gastrocnemius stretching exercises according to the patient's condition. If the patient does not experience discomfort in the plantar fasciae, it is recommended to perform the gastrocnemius stretching exercise only without myofascial release and use a massage ball afterward.
