Implication

Systematic review reveals variable accuracy and high parameter sensitivity in multibody kinematics optimization for human joints, highlighting the need for standardized validation and personalization.

Key Points

Identify numerical methods, validation techniques, and kinematics estimation performance of multibody kinematics optimization applied to human joints.
Screened 74 papers identified via a systematized search across five electronic databases and cross-referencing.
Assessed computational frameworks (constrained optimization, Kalman filtering), sensor inputs (skin markers, electromagnetic, inertial sensors), and joint constraints (hinge, spherical, parallel, and elastic mechanisms).
Validation against ground-truth bone kinematics revealed errors ranging from 1 deg to 22 deg for tibiofemoral rotations and from 3 deg to 10 deg for glenohumeral rotations.
Model reconstruction residual errors spanned 4 mm to 40 mm, with sensitivity analyses demonstrating parameter-induced variations reaching up to 36 deg and 12 mm.
Repeatability evaluations demonstrated low intra- and inter-observer variability, though simulation-based evaluations frequently relied on oversimplified soft tissue artefact assumptions.
