Seating & Positioning Clinics

DIDD operates three seating and positioning clinics in Tennessee, located in Arlington, Nashville, and Greeneville.  Mobile on-site services are available in east and west Tennessee.  Physical and occupational therapists with specialized expertise in evaluating complex seating and positioning needs provide comprehensive evaluations and support to prioritize needs.  Each clinic has an associated manufacturing shop where staff with extensive experience in the areas of construction, carpentry, upholstering, and electronics, fabricate equipment to meet individualized needs.  For more information and to learn about the benefits of seating and positioning, download our brochure.

Referrals for a repair of equipment fabricated by the Seating and Positioning Clinic:

When a wheelchair needs repairs (frame, headrest, brakes, wheels, etc.), a durable medical equipment (DME) vendor needs to be contacted, since the DME vendor can bill an individual’s insurance for the parts and labor (DIDD cannot bill for parts and labor). For the most part, any DME in the network for the individual’s insurance can be contacted for repairs. If problems are encountered that are difficult to resolve, individuals can contact the clinic for guidance.
When a piece of equipment is delivered through our clinic, we issue a competency form that explains how to help a person into the equipment, how to clean it and who to contact for repairs.  Please review this form and maintain it for reference.
When components of the wheelchair or alternative positioning equipment manufactured by DIDD are in need of repair, the following form should be completed and sent to the clinic.
