Hand osteoarthritis (OA), a common joint disorder affecting about 70 percent of people aged 65 years and older, usually results in decreased strength and function of the hand and deficits in motor control. This study investigated the relationships between the parameters of grip force control during an object lifting task and the outcomes of functional and clinical tests commonly used in the assessment of hand function in individuals with hand OA. The results of this study showed that there were strong correlations between the outcomes of hand functional tests and parameters of grip force control in patients with hand OA. For instance, the Moberg Pickup Test was strongly correlated with the magnitude of grip force and the time spent lifting the object. This information will help to improve clinical and functional diagnostic tests for the individuals with hand OA and, therefore, provide new data for development of more focused physical therapy interventions.
