Comparison of two handgrip dynamometers in older adults before elective surgery
Authors' conclusion
Camry digital dynamometer is an inexpensive and valid device to measure handgrip strength in older adults previous to elective surgery, compared to the gold standard Jamar® hydraulic handgrip dynamometer.
