With the emerging promising reports confirming the accuracy of the dynamometer for assessing PFM strength in various women groups and for investigating stress UI, a portable dynamometer has recently been developed by our collaborators at the Auckland Bioengineering Institute (ABI), led by Professor Poul Nielsen [15]. The device has several advantages over other designs: (1) It is hand-held, portable; (2) It is designed to be operated by a medical professional; (3) It measures in the coronal as well as the anteroposterior orientations; (4) Data acquisition is at a high frequency (100Hz) and can be automated, and (5) Parameters are adjustable to required protocols.
