Abstract

<abstract> <title> <x xml:space="preserve">Abstract</x> </title> <p> <italic>Purpose</italic>: To clarify the features of gait in patients with congenital insensitivity to pain (CIP) by analyzing the video-recorded gait.</p> <p> <italic>Methods</italic>: Eleven patients with the diagnosis of hereditary sensory and autonomic neuropathy (HSAN) type 4 or 5 and 15 healthy participants were enrolled in this study. Gait was analyzed using two-dimensional (2D) digital video and video analysis software. Walking speed, cadence, step length, stance phase duration, and heel contact to foot flat period were compared between patients and healthy participants.</p> <p> <italic>Results</italic>: The results showed that walking speed and heel contact angular velocity were significantly higher (<italic>p</italic> &lt; 0.05), and step length was significantly longer (<italic>p</italic> &lt; 0.05) in CIP patients, especially in the younger age group.</p> <p> <italic>Conclusion</italic>: Young patients with CIP walked faster, with a longer step length and higher heel contact angular velocity than young control participants. These results may explain the frequency of lower extremity injuries in CIP patients.</p> </abstract>
