Active Health Performance Lab

Objective data meets clinical expertise

Every comprehensive performance assessment combines hands-on sports chiropractic evaluation with technology that gives you objective information about your movement quality, force output, and nervous system response.

Bilateral Force Testing

Medical-grade dynamometry measuring left vs. right strength to calculate your Limb Symmetry Index (LSI). Identifies meaningful asymmetries that may be limiting performance or increasing injury risk.

Movement Analysis

Joint-by-joint screening using FRC and PRI principles to identify restrictions, compensations, and motor control deficits. Markerless motion capture to visualize movement patterns in 3D.

Biofeedback & Muscle Activation

Surface EMG technology that displays real-time muscle activation during corrective exercises. Helps you see when muscles are firing correctly, making motor learning more effective.

Heart Rate & HRV Assessment

Autonomic nervous system measurement during the performance assessment. Heart rate variability and resting heart rate data inform clinical decisions about your body's readiness and stress response.

Leave with numbers you can track over time

Every assessment produces a detailed performance report with your objective baselines. Reassess quarterly to see measurable progress — not just how you feel, but how you're actually performing.

📊

Data-Driven People

Anyone who values measurable progress over subjective assessments and vague timelines

Complex problems, systematic solutions

These are the cases we see most often — and the ones we're best equipped to help with.

Return-to-Sport After Injury

ACL, labral repair, Achilles — when PT is complete but you're not quite ready to compete

Chronic Joint Pain

Shoulders that won't heal, hips that won't unlock — often motor control problems, not tissue problems

Movement Limitations

Can't squat deep, can't reach overhead, can't rotate — restrictions that limit performance and increase risk

Performance Optimization

Already healthy but want to move better, maximize force output, and build joint capacity

Our Clinical Approach

We use Functional Range Conditioning (FRC), Postural Restoration Institute (PRI) techniques, instrument-assisted soft tissue mobilization, dry needling, and evidence-based manual therapy.

Our approach focuses on measurable, functional goals. Treatment plans are based on your actual progress. We work to restore mechanical function and motor control.

Common questions

What is a Performance Assessment at Active Health?

A 90-minute comprehensive evaluation combining bilateral force testing with medical-grade dynamometry, joint-by-joint movement screening using FRC and PRI principles, surface EMG biofeedback, markerless motion capture, and heart rate variability measurement. You leave with a detailed performance report and prioritized treatment plan.

What is Limb Symmetry Index (LSI)?

Limb Symmetry Index is the ratio of force output between your left and right sides for a given movement. An LSI of 90% or above is the widely cited return-to-sport threshold. Scores below 90% indicate meaningful asymmetry that may increase injury risk and guide treatment priorities.

Who should get a Performance Assessment?

Athletes returning from injury, post-surgical patients transitioning from PT, active adults with persistent movement problems, and anyone who values measurable progress over subjective assessments.

How often should I reassess?

We recommend quarterly reassessments — every 12 weeks — to track objective progress and update your treatment plan based on real data.
