Subjective rating scales like Scale for the Assessment and Rating of Ataxia (SARA) may underestimate gait severity. Inertial measurement units (IMUs) offer an objective gait analysis. Impaired trunk control might compromise gait performance and stability in individuals with ataxia. This study quantified trunk kinematics and gait parameters using Root Mean Square (RMS) values, comparing CA to healthy individuals. Ten CA cases and twenty healthy controls were recruited. Six IMU sensors positioned at anatomical landmarks recorded data via two ESP32 microcontrollers using Wi-Fi. Participants walked a 10-meter path at a self-selected pace. RMS mean linear and angular velocity and angular deviation were calculated. Individuals with CA showed decreased mediolateral linear acceleration at the left shoulder (\n                    <jats:italic>p<\/jats:italic>\n                    \u2009=\u20090.001) and an increased vertical linear acceleration at the right ankle\n                    <jats:italic>(p\u2009=\u20090.015)<\/jats:italic>\n                    , left shoulder\n                    <jats:italic>(p\u2009=\u20090.028)<\/jats:italic>\n                    , and back (\n                    <jats:italic>p\u2009=\u20090.019<\/jats:italic>\n                    ).
