A full athletic assessment combining Vald force plates, Vald Dynamo strength and range of motion testing, and a skilled physical therapist provides a clear picture of how you move, where you are strong, and where you may be at higher risk of injury. At Prep Physio Therapy in East Islip NY, this data helps guide smarter training decisions, supports injury risk reduction, and gives athletes of all ages a roadmap to improve performance safely.

Why a Thorough Athletic Assessment Matters

If you are an athlete or active adult, you already know working hard is not the problem. The challenge is knowing what to work on.

A full athletic assessment goes beyond a quick screen or generic fitness test. It combines movement analysis, objective strength and range of motion data, and sport specific context to answer questions like:

  • Where are you strongest and where are you compensating
  • Are you loading one side more than the other
  • Do you have the mobility and control your sport demands
  • What training changes will give you the best return for your effort

At Prep Physio Therapy on Main Street in East Islip, we use Vald force plates and the Vald Dynamo system along with skilled physical therapy to help athletes from middle school through adulthood get clear answers to these questions.

Meet the Tech: Vald Force Plates and Dynamo

Vald systems are medical grade devices with regulatory approvals such as the CE mark. They are designed to capture precise data on how your body produces and controls force.

What Are Force Plates

Force plates are sensitive platforms you stand on, jump from, or push against. They measure how much force you produce, how quickly you produce it, and how that force is distributed between your limbs.

In the clinic, Vald force plates can help your physical therapist:

  • Compare right and left leg power and landing forces
  • See how you control your body during squats, jumps, and landings
  • Track changes over time as you train or recover from injury

This is especially useful for field and court athletes, runners, and anyone whose sport demands power, cutting, or jumping.

What Is Vald Dynamo ROM and Strength Testing

The Vald Dynamo is a handheld system that measures strength and range of motion. It also carries relevant regulatory approvals such as the CE mark.

With Dynamo, your physical therapist can:

  • Measure joint range of motion in degrees instead of just saying “tight” or “loose”
  • Test muscle strength in specific positions and record it in real numbers
  • Compare you to your other side or to expected values for your age and sport level

This is incredibly helpful for shoulders, hips, knees, ankles, and the spine, especially in overhead athletes, runners, and lifters.

Why a Skilled Physical Therapist Still Matters

Technology is powerful, but the real magic is how it is interpreted and used. A skilled physical therapist ties the data back to you.

At Prep Physio Therapy we:

  • Watch how you move during sport specific patterns, not just in a straight line
  • Ask about training volume, schedule, and past injuries
  • Combine force plate and Dynamo results with hands on assessment of mobility, strength, and control
  • Explain the results in plain language so you know exactly what they mean

Two athletes can have similar numbers but very different needs based on their sport, position, and training history. Your PT makes sure the plan fits your goals, not just the data.

How This Assessment Helps Athletes at Every Level

Middle and High School Athletes

These years are huge for development. Growth spurts, new positions, and more intense competition all show up in how you move.

A full athletic assessment can help younger athletes:

  • Catch early strength or mobility imbalances before they become bigger problems
  • Learn how to land, cut, and decelerate with better control
  • Build a simple strength and movement plan that supports club and school practices

Parents also appreciate having objective data instead of guessing whether their athlete is “ready” for the next level of training.

College Athletes and Competitive Adults

At higher levels, the margin between playing and sitting is small. College and serious adult athletes benefit from data driven decisions.

Your assessment can help you:

  • Identify weak links that may limit speed, power, or endurance
  • Fine tune strength and conditioning programs during off season and in season
  • Track readiness and fatigue by seeing how jump or force outputs change over time

This is especially helpful for return to play decisions after an injury, always in coordination with your medical team.

Active Adults Who Love to Train

You do not have to be on a roster to move like an athlete. Many active adults in East Islip run, lift, play in leagues, or train for fun.

An athletic assessment can:

  • Highlight areas to focus on so workouts feel better and safer
  • Provide clarity if you keep feeling the same nagging spot each time you ramp up
  • Offer specific strength or mobility targets rather than generic “stretch more” advice

It is a great option if you want to invest in your longevity and keep doing what you love for years.

What Happens During a Full Athletic Assessment at Prep Physio

Every athlete is different, but a typical session may include:

  1. Goal setting and history
    Your PT talks through your sport, training schedule, injuries, and goals.
  2. Movement screen
    Simple patterns like squats, lunges, step downs, hops, or arm movements to see how you control motion.
  3. Vald force plate testing
    Depending on your sport, this may include:
    • Countermovement jumps or landings
    • Isometric strength tests such as a mid thigh pull or calf raise
    • Balance or stability drills to see how you control your center of mass
  4. Vald Dynamo strength and ROM testing
    Your PT measures key joints and muscles, for example:
    • Hip rotation and strength for field athletes and runners
    • Shoulder rotation and cuff strength for throwers and overhead athletes
    • Quadriceps and hamstring strength for jumping and cutting sports
  5. Review and next steps
    You get a clear explanation of your results, how they relate to your sport, and what to work on.

Throughout the process, you will have plenty of time to ask questions and make sure you understand what the numbers mean.

Turning Data Into a Simple, Practical Plan

Data alone does not make you better. What matters is how you use it.

After your assessment, your physical therapist can:

  • Highlight your top 2 to 3 priorities instead of handing you a huge list
  • Build a focused strength, mobility, or power program based on your results
  • Coordinate with coaches or trainers if you want everyone on the same page

For some athletes this looks like a short block of targeted PT sessions. For others, it might be a home or gym program you follow on your own with periodic re testing.

Is a Full Athletic Assessment Right for You

You might benefit from this kind of assessment if:

  • You are an athlete returning from an injury and want a clearer picture of readiness
  • You feel “fine” but want to reduce risk as you increase your training load
  • You are stuck at a plateau in speed, power, or strength
  • You are a parent or coach who wants objective insight for a young athlete

It is also a smart move before a busy season, a big training block, or if you are switching sports or positions.
