The Range of Motion (ROM) is an important index of physical and occupational therapy, although getting quantitative results requires much time and effort. This paper proposes a method for measuring the ROM on a 2-dimensional plane by introducing a rehabilitation robot. One advantage is that quantitative measurement is easily done. This paper also proposes the concept of resistancemovementROM, which indicates the extent of movement under load and resistance. This method makes it possible to observe the distribution of strength within the ROM. In other words, the proposed method evaluates upper limb mobility and the ability to produce force. The feasibility of the method is evaluated through experimental results.
