When patients come to physical therapy, one of the most frustrating things is not being able to see their own progress. They feel like they're working hard, but how do you measure something like posture, symmetry, or body composition in a way that's objective?
That's where our Fit3D body scanner comes in — and it's one of the things that sets our PT program apart.
What Is the Fit3D Scanner?
The Fit3D ProScanner is a 3D body imaging system that creates a detailed three-dimensional model of your body in about 40 seconds. You stand on a rotating platform while infrared sensors capture thousands of data points, and the system outputs:
- 3D body model — a visual representation of your posture and body shape
- Body composition estimates — lean mass, fat mass, and more (validated against DEXA scan)
- Postural analysis — shoulder height, hip tilt, spinal alignment, head position
- Circumference measurements — waist, hips, chest, arms, thighs — precise to the millimeter
- Symmetry analysis — left vs. right differences in muscle mass and posture
How We Use It in Physical Therapy
Baseline Assessment
At the start of your PT program, we do a baseline scan. This gives us an objective starting point: your current posture, any asymmetries we need to address, and your body composition at the start of rehab.
Tracking Progress
We repeat scans at regular intervals — typically every 4-6 weeks. This lets us quantify changes that are otherwise hard to measure. Did your hip drop improve? Did you regain muscle mass in your quad after ACL surgery? Did your posture improve with our thoracic mobility work? The scan tells us.
Identifying Asymmetries
One of the most valuable uses of the Fit3D is identifying asymmetries — left-right differences in muscle mass or posture that can predict injury risk. A runner with significantly more quad mass on one side, or a pitcher with asymmetric shoulder height, may be setting themselves up for an overuse injury. We can see these things in the scan and address them proactively.
Motivating Patients
Let's be honest: motivation is part of PT. Seeing objective numbers improve — a posture score going from "moderate deviation" to "optimal," or seeing your injured leg rebuild muscle mass to match the healthy side — keeps patients engaged and working.
Who Benefits Most
- Post-surgical patients who need to track muscle mass recovery (ACL, rotator cuff, hip replacement)
- Athletes who want to optimize symmetry and reduce injury risk
- Patients with chronic postural issues — forward head posture, scoliosis monitoring, shoulder impingement
- Anyone in a long-term PT program who wants to measure their progress quantitatively
What the Scan Does NOT Do
The Fit3D is a screening and tracking tool, not a diagnostic device. It doesn't replace X-rays, MRIs, or clinical examination. It's one piece of a comprehensive assessment — and the most important piece is always the clinical reasoning of your physical therapist.
