FIHM Measurements

The customer’s challenge

FOB Startup wanted to use to create a device for performing measurements on the functional strength of the intrinsic hand muscles, FIHM measurements. Such a product would be able to contribute to health care treatment and rehabilitation for hand and wrist injury and disability. Physiotherapists, doctors, and other medical specialists would be able to use it to evaluate the functional intrinsic muscle strength of their patients.

ABA Electronics’ contribution

ABA Electronics designed and developed the electronic hardware, embedded software, and created the desktop application software for testing, calibration, and programming purposes. Special care was taken in developing a product with low-power usage and reliable Bluetooth communication.


Instead of an extensive health check system, specialists can now rely on the FIHM measurements for the evaluation of their patients. The ultra-low-power usage makes it possible to use the FIHM for an extended period of time in which the highly reliable Bluetooth link ensures that there is no loss of data.
