humac norm isokinetic dynamometer extremity system with feature callouts
"I have 30 years of experience with quantification of human performance in the setting of both clinical and research testing. I have used nearly every dynamometer system available beginning with the “chain” driven models. My current facility had a history of needing to replace the system every 4-5 years because of heavy use. When replacement was last required, I pushed for the HUMAC Norm, which we have now had for 5 years and do not anticipate needing to replace it again."
