Material: Wood This is a sanding board for rehabilitation that can be used on a tabletop. Since manufacturer products cost over 60,000 yen, this was DIY-made for arm rehabilitation. The angle can be adjusted in 3 stages, approximately 25 degrees, 30 degrees, and 40 degrees. By moving the upper limbs widely, sliding them across the surface of the sanding board, it is expected to expand the range of motion of the joints and strengthen muscles. In occupational therapy, it is widely used in hospitals as a training tool for improving upper limb function. A sanding block is also included. The load can be adjusted by attaching a weight to the center of the handle. How about it for self-training at home or for those who don't have sanding equipment at facilities? It is made to the size of a general sanding board. Since it is DIY-made, there is no warranty. Please consider this if you are okay with that. Dimensions: 780mm (length) x 300mm (width) x 60mm (height when folded) *It will be made after the purchase, so it will take about a week.
