Therapeutic Potential of 3D Printing Pen in Stroke Rehabilitation: Case Reports

Abstract

Medical applications for 3-dimensional (3D) printing are rapidly expanding and are expected to revolutionize health care. Two patients with chronic stroke participated in a training program with the 3D printing pen (3Doodler 2.0; WobbleWorks, Inc.). This training program consisted of 12 sessions for 4 weeks. The training program consisted of a 4-step protocol. In 2 patients with chronic stroke who showed impaired visuospatial function and hand function, each function improved without any serious adverse effects after completing training. This case study suggests the therapeutic potential of the 3D printing pen to improve visualperceptual and hand functions in stroke patients.
