The Test Is Only as Good as the Clinician Using It
Turning objective data into better rehabilitation and return-to-sport decisions
Technology continues to give physical therapists better ways to measure strength, identify deficits and track progress. But having more data doesn’t automatically lead to better care.
The value comes from knowing what the data means and what to do with it.
That was a major focus of a recent clinician education course at Rehab 2 Perform, led by Dr. Sydney Williams, DPT, SCS, MS, centered around the HUMAC NORM isokinetic testing system and how objective strength testing can inform rehabilitation and return-to-sport decisions.
What Does Isokinetic Testing Add to Physical Therapy?
Traditional strength testing can provide a useful snapshot of what an athlete can produce at a particular point in time.
Isokinetic testing allows clinicians to look deeper.
Using the HUMAC NORM, R2P physical therapists can assess strength and force production throughout a range of motion at controlled speeds. This can help identify deficits and asymmetries that may not be as apparent through traditional testing alone.
But the goal isn’t simply to collect more numbers.
The question is: What do those numbers change?
Turning Testing Into Better Rehab Decisions
Objective testing becomes most useful when it influences what happens next in rehabilitation.
A finding may help a clinician determine whether an athlete needs additional strength development, improved motor control, greater tolerance to load or a different exercise progression.
That information can then help guide exercise selection, loading and progression based on the individual athlete rather than relying on a standardized approach.
Testing can also help answer increasingly demanding return-to-sport questions:
Are they ready to run?
Are they ready to sprint?
Are they ready for unrestricted sport?
Rather than relying on time or pain alone, objective testing provides another piece of information clinicians and athletes can use when making those decisions.
Technology Doesn’t Replace Clinical Reasoning
One of the most important points from the course had little to do with the HUMAC itself:
If you don’t know what you’re looking at, you can’t make a decision from it.
A strength deficit, motor-control issue and load-tolerance problem may require very different approaches in the clinic.
That’s why investing in technology has to come with an investment in clinician education, interpretation and application.
For R2P, the goal of bringing clinicians together for courses like this isn’t simply learning how to operate another piece of equipment. It’s continuing to develop how our team assesses athletes, interprets objective information and translates those findings into better rehabilitation decisions.
Building a Better Return-to-Sport Process
No single test determines whether an athlete is ready.
At R2P, objective testing is used alongside clinical assessment, rehabilitation progressions and an understanding of the demands an athlete needs to return to.
The HUMAC NORM gives our clinicians another powerful source of information within that process.
Because the finish line isn’t simply being pain-free.
It’s being prepared for what comes next.
About the HUMAC NORM
The HUMAC NORM is considered a gold standard in isokinetic strength testing, providing objective data on strength and force production throughout a range of motion at controlled speeds. At R2P, our clinicians use HUMAC testing alongside clinical assessment and performance testing to identify deficits, guide individualized rehabilitation and help inform return-to-sport decisions.
