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.
B-Alert X-Series Systems offer top of the line wireless EEG. Participants are much more comfortable in B-Alert systems, ensuring the best outcome for data quality. With a super easy setup, B-Alert X24 allows researchers to collect up to 20 channels of EEG and concurrently record physiology signals in combination with BIOPAC’s data collection systems.
• Learn new features of the B-Alert X24, including the 10/20 electrode montage system • Discover real-time subject classifications for engagement, confusion/distraction, drowsiness, workload, and stress • Integrate and synchronize other physiology signals including EDA, EMG, respiration, and temperature
Rehabilitation with Sudoku Sudoku, in the last 10 years, has seen a resurgence in popularity as a challenging logic game. Scientists have also fallen in love with the math puzzle, as a useful tool for neurorehabilitation and cognitive workouts. This study measured prefrontal cortical activity with a continuous-wave fNIR Imager to observe how participants solved […]
