In the world of physical therapy, precision is everything—especially when it comes to helping athletes and active adults recover from injury and return to peak performance. Yet, many rehabilitation programs still rely heavily on outdated tools like manual muscle testing (MMT) to assess strength.
While MMT can offer a general idea of a patient’s capabilities, it lacks the objectivity, consistency, and sensitivity required for high-level performance and injury prevention. At Cohen Health and Performance, we believe it’s time to stop guessing and start measuring.
The Limitations of Manual Muscle Testing
Manual muscle testing is a common practice in many physical therapy clinics. A therapist applies pressure to a limb and grades the patient’s strength based on resistance. While this method may help screen for gross weakness, it’s highly subjective.
Key limitations include:
- Lack of precision
- Inability to detect small, yet important, strength deficits
- Inconsistent results between therapists
- No ability to track subtle changes over time
When returning an athlete to sport, especially after a major injury such as an ACL tear, rotator cuff strain, or ankle sprain, relying on manual testing alone can lead to premature clearance—and an increased risk of reinjury.
Objective Strength Testing in Modern Physical Therapy
Today’s leading physical therapy practices (like Cohen Health and Performance if I don’t say so myself) use objective strength testing tools to deliver data-driven care. Whether through isometric testing devices, force plates, or handheld dynamometers, the goal is the same: measure what matters and act on real data.
Benefits of objective testing include:
🔹 Identify muscular imbalances
Catch asymmetries or deficits in strength between limbs, which are often invisible with manual testing.
🔹 Set clear, measurable goals
Define baseline numbers and establish precise strength benchmarks for return-to-sport decisions.
🔹 Reduce risk of reinjury
Research shows that inadequate strength—especially side-to-side deficits—increases reinjury risk. Objective testing ensures no major gaps are left unaddressed.
🔹 Optimize recovery timelines
Tracking strength improvements over time allows therapists to adjust training loads and progressions with confidence, ensuring that recovery is both safe and efficient.
Why It Matters for You
Whether you’re an elite athlete or an active adult who wants to stay in the game, data matters. When your recovery is based on objective strength testing, you’re no longer relying on a therapist’s best guess—you’re following a personalized plan grounded in science.
At Cohen Health and Performance, our team uses cutting-edge tools and technology to assess your progress and guide your recovery every step of the way. We don’t just help you feel better—we ensure you’re performing better.
