Objective Testing. MeasurableProgress. Stronger Documentation.

HumanTrak is a markerless 3D motion-capture system that helps document how an injury affects a patient’s movement, balance, mobility, and everyday function.

Using a single depth-sensing camera and machine-learning technology, HumanTrak:

• Identifies the patient’s anatomical landmarks
• Reconstructs movement as a three-dimensional skeleton
• Measures joint angles, range of motion, rotation, and displacement
• Evaluates balance and center-of-mass control
• Detects asymmetries and compensatory movement patterns
• Produces clear, objective visual reports
• Compares results across multiple evaluations

Pain can be subjective, but functional limitations can be measured. HumanTrak can provide objective evidence showing:

• Restricted range of motion
• Abnormal or guarded movement
• Balance and stability deficits
• Differences between the injured and uninjured sides
• Compensations involving the trunk, pelvis, hips, knees, or feet
• Persistent limitations despite treatment
• Measurable improvement—or lack of improvement—over time

Repeated testing establishes a measurable baseline and tracks the patient’s recovery. Persistent deficits may help the treating provider explain:

• Why continued rehabilitation is medically necessary
• How the injury affects daily and functional activities
• Whether the patient has fully recovered
• Why future physical therapy or periodic reevaluation may be needed
• The clinical basis for anticipated future-care costs

Pain and weakness can be difficult to demonstrate through observation alone. DynaMo provides objective measurements that help clinicians document how an injury affects a patient’s strength, mobility, and physical function.

DynaMo is an advanced handheld dynamometer and inclinometer. It combines multiple testing capabilities in one portable system, allowing clinicians to evaluate strength and range of motion across every major joint in the body.

It can measure:

• Pushing and pulling strength
• Grip strength
• Joint range of motion
• Side-to-side strength differences
• Physical progress across multiple evaluations

DynaMo can be used handheld or secured to a wall, treatment table, cable, or patient’s limb for greater testing consistency.

During an evaluation, the clinician positions DynaMo to test a specific joint or muscle group. The patient pushes, pulls, grips, or moves through a prescribed motion while the device measures the force produced or the available range of motion.

Results appear in real time, are automatically saved to the patient’s profile, and can be presented in detailed progress reports. This creates a consistent record that can be compared throughout treatment.

DynaMo can provide objective clinical evidence of functional impairments following an accident or injury, including:

• Muscle weakness
• Reduced joint mobility
• Loss of grip strength
• Differences between the injured and uninjured sides
• Persistent limitations despite treatment
• Measurable improvement or lack of improvement over time

These measurements can help support the patient’s reported symptoms by showing how the condition affects physical performance.

Testing at the initial evaluation establishes an objective baseline. Follow-up testing allows the clinician to measure recovery and determine whether the patient’s deficits are resolving or continuing.

Persistent measurable limitations may help explain:

• Why physical therapy is medically necessary
• Why continued treatment is appropriate
• Whether the patient has returned to pre-injury function
• How the injury affects work and daily activities
• Why future rehabilitation or reevaluation may be required
• The clinical basis for anticipated future-care costs

A result may fall within a general reference range while still revealing meaningful differences between the patient’s injured and uninjured sides. For example, both sides may test within normal limits, yet one side may demonstrate reduced motion, strength, balance, or control that correlates with the patient’s symptoms and functional difficulties. If these asymmetries persist, repeated compensatory movement patterns may place additional stress on other joints and tissues, potentially contributing to overuse, altered mechanics, and degenerative changes over time. Documenting these differences—and tracking whether they resolve or persist—provides a more complete picture of recovery and may help identify limitations requiring continued monitoring or care.
