What Happens at a Professional Wheelchair Seating Evaluation

A seating evaluation is the difference between a chair that fits and a chair that just rolls. For full-time users, it's the single most useful clinical visit on the calendar.

Who performs it

An occupational or physical therapist with an ATP (Assistive Technology Professional) credential. Most major rehab hospitals have a dedicated seating clinic.

What they measure

• Hip width, thigh length, lower-leg length, trunk height — to size frame and cushion.
• Range of motion at hips, knees, and ankles — to set seat angle.
• Pressure mapping under the seat — to choose cushion type.
• Postural support needs — to spec lateral and back supports.

What you leave with

A written specification — the document your DME supplier uses to order the chair, and the document Medicare or insurance uses to authorize payment. Bring it with you for second opinions.
