We conduct a wide variety of rehabilitation programs for patients with cognitive disorders. Patients have often presented decreased levels of awareness, associated with decreased levels of motivation, while participating in rehabilitation activities. To define the goal of a horticultural rehabilitation program, we developed two tables associating cognitive functions, contents, and difficulty levels of the rehabilitation tasks performed by the patients. Table 1 demonstrates a task construction combining specific body and cognitive functions needed to perform the specified task. Table 2 classifies a task according to the difficulty level of each process involved. The processes listed in Table 2 are hierarchically divided into four functions: (1) attention and information processing, (2) memory and executive function, (3) upper limb and finger function, (4) lower limb and balance function. After applying these tables to a rehabilitation program, the level of awareness of one individual gradually increased. Using this program, a new goal was set for this patient, ultimately allowing him to rehabilitate himself into the community. These findings showed that these tables, which aim to help visualize cognitive and motor information, were useful in creating opportunities for self-feedback. This method was effective in improving self-awareness and determining the patientʼs personal limitations, and helped understanding of the purpose of the rehabilitation.
