Human motion analysis has several applications including biomedical and athletic performance. To conduct a biomedical analysis, patient movements are recorded, digitized, copied on computer, and processed. For example, when calculating net joint moments, the joint center is calculated using a local coordinate system created from body markers. When tracking markers in 3D using video, two or more cameras are used to identify the markers. After all parameters are found, the resultant net joint forces and movements can be calculated. In 3-D kinematics, joint centers are digitized for the first few frames of the sequence recorded. Linear parameters of movement can be measured to assess horizontal and vertical motion. Also, angular parameters can measure the degrees of movement of the joints to analyze specific joint motion. In 96001, while taking dynamic plantar pressure measurements, data is collected using a pressure sensor platform positioned on a walkway. The patient walks along the walkway so pressure data can be analyzed in areas of the foot (e.g., the heel, metatarsal heads, and the hallux). The peak pressure is determined in all areas and the highest pressure of all sites (i.e., peak pressure foot) is measured. Report 96004 in addition to each of these codes for physician review and interpretation of results, which includes the physician’s written report.
CPT® 96002 – Dynamic surface electromyography, during walking or other functional activities 1-12 muscles
Electrodes placed on the muscle belly, parallel to the grain of the muscle fiber, detects an electrical signal that comes from active muscles (the patient is in motion during the test). The strength and pattern of the signal is seen on a computer screen and the data is collected in a software program that is able to run various analyses of the data to create useful reports regarding muscle function. For example, gait analysis allows the clinician to analyze time normal activation patterns separately for stance and swing phases between conditions or against data base values. Report 96002 for a study of one to 12 muscles.

Assistive Technology Assessment
CPT® 97755 – Bill 2 units
2D Gait assessment, Balance test
Sensor Medica Systems:
- freeMed Walkways
- FlexInFit In-Shoe Sensors
- Runtime Treadmill
A health care provider performs an assessment for the suitability and benefits of acquiring any assistive technology device or equipment that will restore, augment, or compensate for existing functional ability in the patient or that will optimize functional tasks and/or maximize the patient’s environmental accessibility. This code is reported for one-on-one patient contact time, per 15 minutes, and includes the preparation of a written report.
Physical Performance Test
CPT® 97750 – Bill 2 units
Range of Motion
Sensor Medica Systems:
- Moover One Range of Motion
The health care provider performs a test of physical performance evaluating function of one or more body areas and evaluates functional capacity. A written report is included. This is in addition to a routine evaluation or re-evaluation (97161–97172). This code can be reported in 15-minute increments.
