Validity and Reliability of a Low-cost Chair Dynamometer

October 23, 2020 updated by: Søren Krogh Jensen, Spinal Cord Injury Centre of Western Denmark

In part 1 of the study, fourteen able-bodied individuals will undergo maximal, voluntary contraction (MVC) test of the lower limbs in two dynamometers. One being a low-cost dynamometer (S2P-CD), and the other being a gold standard dynamometer (HUMAC). Thereby the investigators will be able to assess the validity of the S2P-CD.

In part 2 of the study, eighteen persons with spinal cord injury will undergo MVC twice in the S2P-CD. Thereby the investigators will be able to assess the reliability of the measurements of the S2P-CD.

Detailed Description

In part 1 of the study, fourteen able-bodied individuals will undergo maximal, voluntary contraction (MVC) test of the lower limbs in two dynamometers. One being a low-cost dynamometer (S2P-CD), and the other being a gold standard dynamometer (HUMAC). The tests will be carried out with 72-96 hours between them. Thereby the investigators will be able to assess the validity of the S2P-CD.

In part 2 of the study, eighteen persons with spinal cord injury will undergo MVC twice in the S2P-CD. Participants will be recruited through the Spinal Cord Injury Centre of Western Denmark (SCIWDK). The test will be carried out with 30min between them. Thereby the investigators will be able to assess the reliability of the measurements of the S2P-CD.
