Dynamic duo

The handheld dynamometer measures
the amount of strength and the range
of movement in the joints of limbs
of patients recovering from injuries
such as stroke.

The handheld dynamometer, developed by IRL assistive devices researcher Marcus King, measures the amount of strength and the range of movement achieved by the joints or limbs of patients recovering from injuries such as stroke.

The accurate measurements it takes provide crucial information for physiotherapists who want to closely monitor the rehabilitation of their patients.
 
“We knew there was nothing on the market that performed these functions and could be held easily in the hand but the cost of manufacturing meant it would retail at a price that was very expensive,” says King.

Enter the rapid prototyping division of ITRI, which took the technology and looked at different materials and methods of production aimed at reducing its price.

“We were really impressed with the work put in by the ITRI team. It led to a significant reduction in manufacturing cost to a level where mass production is feasible,” says King.

The project is part of a larger agreement between IRL and ITRI to collaborate on the development of assistive devices for the disabled that was signed in 2008.

King says the rapid development of the dynamometer shows there are real synergies between the two organisations. “We definitely have complementary strengths. ITRI has really shown how it can take a good idea and help turn it into a feasible product for global markets.”

The IRL project team is presently seeking business partners in New Zealand to commercialise the technology.
