This application note reports the performance of BIOPAC hand dynamometers SS25LA and TSD121C at grip forces below 1 kg. These devices are specified to register clench force range 0-50 kgf. Performance was measured using the MP150, MP36/MP36R, and MP45.
An alternative for low grip strength measurements is a Response/Hand Force transducer—SS56L, BN-CLENCH, or TSD114-MRI—which is configured with a high sensitivity pressure transducer. Subjects can squeeze a bulb by hand (or apply pressure via foot, thigh, etc.) to indicate a response. The device can provide reduced hysteresis and improved sensitivity at low levels.
The BioNomadix two channel wireless goniometry amplifier is a dual output device that provide simultaneous measurements around two orthogonal rotational axes (e.g., wrist flexion/extension and radial/ulnar deviations). These units interface with the MP160 (or older MP150) data acquisition and analysis platform and AcqKnowledge software, allowing advanced analysis for multiple applications and supporting acquisition of a broad range of signals and measurements. BN-GONIO can support any […]
