Purpose: The purpose of this study was to analyze the gait patterns of adults with intellectual disability and healthyadults based on collected kinematic data on the lower extremities and to investigate the gait patterns of intellectuallydisabled people by comparing the differences between the two groups.
Methods: The participants were divided into in one group of healthy adults (n = 9) and one group with mild intellectualdisabilities (n = 9). 3D motion analysis (Myomotion) was used to collect kinematic data from each group while theparticipants walked 3 times over 10 m. As a statistical method, each group’s kinematic data during walking was analyzedand compared using an independent sample t-test.
Results: Comparing the kinematic data of the lower extremities during walking between the group with mild intellectualdisability and the healthy group, there were significant differences between the two groups in the hip and ankle jointsin the stance and swing phases.
Conclusion: The analysis suggests that people with intellectual disabilities have kinematic differences compared withhealthy people. Based on the results of this study, it is necessary to conduct further research on rehabilitation programsfor joint stabilization, exercise for increasing joint range of motion, muscle strengthening exercise, and proprioceptiontraining for people with intellectual disabilities with insufficient physical function.
