Device For Measuring Knee Torque In Bedridden Humans And Method For Using The Device

The invention relates to a portable device for measuring knee joint torque during static muscle contraction in bedridden or immobile individuals. The device enables reliable assessment of muscle strength in patients who are unable to leave their bed or assume a seated position required by conventional dynamometers.

The device comprises a base plate positioned under the patient’s hips, fixation means for stabilizing the body, a mechanical dynamometer framework with adjustable elements, a torque sensor, a shin fixation brace, and an electronic unit for data acquisition and processing. The construction allows measurements of both legs in a supine position, easy adjustment according to patient dimensions, and improved portability.

The invention provides accurate and accessible muscle function assessment in hospital, nursing home, and rehabilitation environments.
