Wheelchair Activity Arches and Motor Planning Dens are two products sensory therapists love. They provide engaging opportunities for gripping and manipulation, through crossing the midline; flexibility and range of motion to exercise. Easels and Arches support upper extremity strength and stability, hand and wrist positioning, and fine motor control. Vertical interactions require a different set of muscles from flat or table top activities. Activity arches are an ideal piece of equipment to address tactile needs and play skills for your clinic or classroom while enabling everyone to get into the play. Play is Powerful and TFH Canada provides Therapy. Freedom. Happiness for everyone.
