Imu-based kinematic analysis to enhance upper limb motor function assessment in neuromuscular diseases.

The analysed sample was small, and eight children were excluded because sensors detached or failed. The study was cross-sectional and did not test whether the IMU system predicts disease progression or improves treatment decisions. Testing was done in a controlled clinic setting with video, not at home or school. The kinematic model used rotational joint motion only and did not include scapular movement or translational shoulder motion. Muscle strength was not measured, so movement limits from weakness and stiffness cannot be separated. Curve efficiency and hand speed were affected by the speed children chose, because no fixed speed was instructed. Brooke categories had few participants in some levels, limiting detailed severity analysis.

Do not conclude that the IMU system has been shown to improve care or to replace clinician assessment. The study measured movement during a clinical assessment in a controlled setting, not patient outcomes or treatment benefit, and sensor problems led to exclusions.
