Abstract
Abstract. Objective: to estimate upper limb net joint moments during wheelchair propulsion movement using OpenSim´s MoBL-ARMS dynamic upper limb model. Methods: trials of a person propelling a wheelchair at a comfortable speed were recorded using an infrared video camera system and two SmartWheels adapted to the wheelchair, experimental data was then analyzed using an OpenSim upper limb musculoskeletal model. Results: mean values for angular kinematics and net joint moments. Conclusion: upper limb angular kinematics and joint moments were calculated, average max moment found for elbow flexion was -4.74 Nm, shoulder rotation 55.43 Nm, shoulder elevation -19.77 Nm, forearm rotation -1.22 Nm, wrist deviation 6.07 Nm and for wrist flexion 2.22 Nm. Direct comparisons of our results with values reported by other authors was difficult mainly because differences among models and experiment setups of the studies. More trials for the same and different speeds are needed to verify the coherence of the approach.
