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.
Easily record great electrodermal activity (EDA, GSR) data. BIOPAC’s new Smart Amplifiers are designed for great data. Smart Amplifiers improve performance by amplifying the physiological signal close to the subject, which allows a high-level voltage connection to the data acquisition system and reduces noise artifact. AcqKnowledge Smart Amp setup includes guides and prompts to prevent […]
BIOPAC provides researchers with a complete range of tools to gather data on heart rate variability (HRV). The following studies demonstrate just some of the ways in which HRV research benefits from the implementation of BIOPAC hardware and software solutions. PTSD and HRV Post-traumatic stress disorder (PTSD) has been associated with dysfunction of the autonomic […]
