Muscle Performance Testing

Primus RS Multimodal Dynamometer:Primus RS multimodal dynamometer from BTE Technologies  is capable of comprehensive muscle performance evaluation through isometric, isokinetic and isotonic testing and evaluation. Output data options include: peak force production, torque vs. speed, and torque vs. angle quantification, and dynamic endurance with detailed power production per repetition. Exercise feedback includes: real time target force tracking, real time work power output, and changes in range of motion for immediate progress comparisons. The Primus RS is a versatile dynamometry system that allows for nearly limitless configurations of the dynamometer head to allow for standard isolated muscle evaluations (quadriceps – knee extension, hamstrings – knee flexion, etc) but also allows for a wide variety of alternative functional testing positions.

Activity Monitoring

The tibial-mounted high-frequency, high-bandwidth wireless physical activity monitor (wi-PAM) has recently been developed and validated at UCSF. The tri-axial accelerometer is securely fixed to the proximal tibia using a knee strap . A durable, flexible ribbon connects the accelerometer to a custom circuit board which includes a 3.7 V, 10 amp-hour battery and a 2 GB micro SD memory card, housed in an ultra high-molecular weight polyethylene casing. An on-board microcontroller (Atmel ATMEGA1284P) maintains constant communication with the accelerometer, reading and recording high frequency vibration. The CPU board and battery are housed in a neoprene sleeve that wraps comfortably around the subjects lower leg. The wi-PAM is designed to be as unobstructive as possible and fit comfortable under casual and athletic clothing, and durable enough to withstand high impacts experienced during typical sporting activities (soccer, football, etc). It can capture triaxial acceleration data at 6000 Hz for 5 continuous days.
