Abstract

Shoulder pain in hemiplegia following stroke is common, and has been associated with subluxation in the gleno-humeral joint. It is hypothesised in the current study that dynamic stability is a more useful measure than subluxation when predicting pain, which will help in the optimisation of treatment options in this group (including neuromuscular stimulation). A system identification technique is used to characterise the dynamic properties of the glenohumeral joint. Random displacement perturbations are applied to the arm, and the force response is measured. Results show that the mechanical properties of the system could be reliably identified using this technique.
