Background: As technology has progressed, various robot-assisted devices have been devel-oped to reduce therapists¡¯ labor and assist in therapy. However, due to their many limitations, it is more practical to use traditional mechanical devices. The grahamizer is one such tradi-tional mechanical device used clinically to rehabilitate the upper extremities. No study has yet established the efficacy of the grahamizer in individuals with stroke.
Objects: This study investigated the immediate change in arm reaching after the use of a grahamizer.
Methods: Twenty-two stroke survivors participated in this study (11 males and 11 females). The reaching of the more-affected arm was measured three times using the three-dimentional electromagnetic motion tracking system ¡°trakSTAR¡±. After the first measurement, the subjects performed 500 rotatory arm exercises using the grahamizer. To assess the grahamizer¡¯s effect, the subjects were remeasured in the same way.
Results: There were significant increases in the reaching distance (p < 0.05) and movement smoothness (p < 0.05) of the more-affected arm after using the grahamizer.
Conclusion: Our study confirms that using the grahamizer is beneficial in the rehabilitation for improving movement of the more-affected arm in stroke survivors.
