Comprehensive computer-based motion analysis by video-taping and 3D kinematics; with dynamic plantar pressure measurements during walking
CPT4 code
Name of the Procedure:
Comprehensive computer-based motion analysis by video-taping and 3D kinematics; with dynamic plantar pressure measurements during walking. Common terms: Motion Analysis, Gait Analysis
Summary
This procedure involves recording and analyzing a person's movement patterns while walking. High-tech video and 3D kinematic systems capture the motion, while specialized equipment measures the pressure exerted by the feet on the ground.
Purpose
This analysis helps diagnose and treat conditions affecting walking and movement. It aims to identify abnormalities, improve mobility, and guide treatment plans.
Indications
- Difficulty walking or abnormal gait
- Chronic pain in knees, hips, or back
- Assessing the impact of neurological or musculoskeletal conditions
- Pre-surgical evaluation or post-surgical monitoring
Preparation
- Wear comfortable, tight-fitting clothes
- Bring any assistive devices (e.g., orthotics, canes)
- Inform the doctor of any recent injuries or surgeries
- No fasting or medication adjustments are typically needed
Procedure Description
- The patient walks across a designated path while being recorded by multiple cameras.
- Reflective markers are placed on key body points to facilitate 3D motion capture.
- Specialized mats or shoe inserts measure the pressure distribution under the feet dynamically.
- Data are analyzed by software to create detailed motion and pressure profiles.
Duration
The procedure typically takes about 60 to 90 minutes.
Setting
Usually performed in a specialized clinical lab or outpatient setting.
Personnel
- Physical therapists
- Biomedical engineers
- Sometimes a physician specializing in rehabilitation or orthopedics
Risks and Complications
This is a non-invasive procedure with minimal risks. Rarely, patients may feel discomfort from markers or positioning.
Benefits
- Precise identification of gait abnormalities
- Tailored treatment plans for improving mobility
- Can prevent further injury or complications
- Insights into the effects of current treatments or surgeries
Recovery
No recovery time is needed. Patients can resume normal activities immediately after the procedure.
Alternatives
- Manual gait analysis by a physical therapist
- Observational studies without dynamic pressure measurement
- Pros: Simpler, less technical
- Cons: Less detailed, potentially less accurate
Patient Experience
During the procedure, patients may feel slight discomfort from the markers or pressure mats but generally no pain. The experience is akin to a typical walking session under observation, with comfort measures provided if needed.
