Why Are ACL Injuries So Common in Female Athletes—and What Can Be Done?


This weekend, I came across an article that caught my eye: “A WNBA Veteran Becomes the Latest Player to Suffer an ACL Tear.” The athlete mentioned was Katie Lou Samuelson of the Seattle Storm—shockingly, the third player on her team to suffer an ACL tear before the WNBA season even begins.

As a physical therapist who works with athletes of all levels, this hit home. ACL injuries are far too common, especially among female athletes. According to the American Journal of Sports Medicine, females are 4 to 8 times more likely to suffer an ACL tear compared to their male counterparts playing the same sport. Even more alarming—over 70% of these injuries are non-contact. That means they’re not the result of a collision, tackle, or fall. They just happen—or so it seems.

But these injuries are not freak accidents. There are clear biomechanical and muscular risk factors that we, as physical therapy professionals, can help address.

Understanding the Risk Factors

One of the most commonly discussed reasons for higher ACL injury rates in females is anatomical structure, particularly the Q-angle—the angle formed by the hip and knee. Due to a generally wider pelvis, many female athletes have a more pronounced Q-angle, which can result in the thighs angling inward (valgus alignment). This creates a greater tendency for the femur to internally rotate and adduct, particularly during high-speed or high-impact movements like jumping, cutting, or landing.

When combined with muscle imbalances, such as strong quadriceps and weak hamstrings or glutes, the risk increases. A poor quadriceps-to-hamstring strength ratio can reduce the knee’s ability to stabilize itself, leaving the ACL vulnerable to tearing under stress.

How Physical Therapy Can Reduce the Risk of ACL Injuries

Preventing ACL injuries is not just about stretching or doing a few leg exercises. A comprehensive physical therapy approach includes:

1. Strengthening the Right Muscles

To protect the knee, we must target the muscles that slow down internal rotation and adduction of the femur—primarily the glutes and deep hip rotators. Strengthening the hamstrings, calves, and core also plays a vital role in protecting the knee joint.

2. Improving Muscle Coordination and Timing

Being strong isn’t enough. Athletes must be able to generate force quickly, particularly during sport-specific movements. That means physical therapy needs to go beyond the weight room.

We bring our athletes to our turf space to practice jumping, landing, cutting, and acceleration drills that simulate real-game scenarios. We analyze landing mechanics and correct faulty movement patterns before they show up on the court or field.

3. Using Data to Guide Programming

Every athlete we work with is evaluated using force plates and other sports technology to understand how their body handles force and movement. This data helps us create a personalized plan to address the specific deficits or imbalances that could lead to an ACL injury.

The Bottom Line: ACL Injury Prevention Starts with Smart Physical Therapy

ACL injuries are devastating. They can take an athlete out of the game for a year or longer. But the good news is—there are things you can do to reduce the risk.

If you are the parent of a female athlete or an athlete yourself and you’re serious about protecting your knees, now is the time to take action. Our ACL prevention programs at Cohen Health and Performance are tailored to each athlete and built on the principles of scientific assessment, personalized physical therapy, and performance training.

Struggling With A Calf or Achilles Injury? What You Need to Know


I’m now at that age where I have to start being more mindful of the nagging calf and Achilles injuries that seem to pop up for so many of us in our 30s, 40s, and beyond. Whether it’s rec league basketball, tennis, pickleball, or just hitting the gym hard, many active adults still love to move with intensity—but we may not have the same resiliency we had in our 20s.

At Cohen Health and Performance, we see it all the time in our physical therapy clinics: a fit, active individual suddenly sidelined by a calf strain. These types of injuries tend to be the first warning sign of lower leg issues that can creep up when we push our bodies beyond what they’re currently prepared to handle.

Why Calf Injuries Happen

A calf strain typically occurs when the loading tolerance of the muscle—its ability to handle force—is exceeded. It’s not always about being out of shape; in fact, many of our patients are in great cardiovascular condition. But if the calf and Achilles haven’t been progressively trained to handle specific types of force—like running, jumping, or quick direction changes—they’re vulnerable.

One of my patients recently told me they went on vacation and, without access to a gym, decided to start running more than usual. They felt fit, so why not? But shortly after, they messaged me with a calf strain. Their cardiovascular system may have been ready—but their calf muscles weren’t conditioned for that repetitive impact. That mismatch between perceived fitness and actual tissue readiness is a common reason we see these injuries in our physical therapy practice.

Physical Therapy for Calf and Achilles Recovery

So what do we do when a calf injury strikes? Or better yet—how can we prevent it?

The key lies in a progressive, personalized rehabilitation plan, and physical therapy plays a critical role in that process. Here’s how we typically approach it:

1. Start with Isometric Loading

We begin with isometric exercises, where the muscle contracts without changing length. This is a safe, low-threat way to begin reactivating the calf muscle after injury. Isometrics help reduce pain, improve blood flow, and reintroduce loading to the tissue without overstraining it. These are often the first steps in any effective physical therapy plan for a strained calf. For more information on isometric exercises, check out this article and video!

2. Progress to Full Range of Motion Drills

Next, we move into more dynamic exercises that take the muscle through a full range of motion. The calf needs to be able to both shorten and lengthen under load, especially if you want to return to activities like running or jumping. These movements are carefully progressed based on how the tissue responds.

3. Introduce Plyometric and Sport-Specific Drills

Once strength and mobility are restored, we introduce plyometric exercises to recondition the tissue for faster, more explosive movements. At this stage, we might use bands or assistance tools to reduce body weight until you’re ready to go full intensity.

Finally, we tailor the program to your sport or activity. Runners may progress to drills like A-skips and A-runs, while basketball or tennis players might focus on reactive jumping or lateral movement training.

Personalized Care is Key

No two injuries—or recoveries—are the same. That’s why every physical therapy plan at Cohen Health and Performance is built around your unique goals, limitations, and lifestyle. Whether you’re returning to a sport or just want to stay pain-free during weekend workouts, we’re here to help you move forward.

If you’ve recently dealt with a calf or Achilles injury—or you’re hoping to prevent one as you stay active into middle age—we’d love to help. Our physical therapy team specializes in helping active adults recover quickly, move better, and keep doing what they love.

How Isometric Exercises Can Boost Your Physical Therapy Success

If you’ve been through physical therapy with us at Cohen Health and Performance — especially after an injury like a tendinopathy or surgery — there’s a good chance you’ve experienced the power of isometric exercises firsthand.

Isometric exercises are a unique and valuable tool we often incorporate into the rehabilitation process. Unlike traditional exercises where muscles actively lengthen or shorten, isometric drills involve maintaining a static position. The muscle remains engaged without changing length, helping it work safely and effectively during early stages of healing.

While these exercises can be surprisingly challenging, one of their biggest benefits is that they’re gentle on healing tissues. This makes them an ideal starting point for anyone recovering from soft tissue injuries like patellar tendonitis, Achilles strains, calf strains, or even surgical repairs. However, as with any aspect of physical therapy, it’s crucial that these exercises are only performed when appropriate for your specific injury.

Why Are Isometric Exercises Important in Physical Therapy?

Isometric drills offer several key benefits during the rehabilitation process:

  • Reduced Pain Sensitivity:
    Research shows that isometric exercises can help decrease pain around an injury. For many patients, this makes it easier to start moving again confidently and safely.
  • Muscle Strength Preservation:
    When other forms of exercise aren’t possible due to injury limitations, isometric holds can help maintain muscle strength, preventing significant deconditioning during the recovery phase.
  • Joint Angle Specificity:
    The strength gains from isometric exercises are specific to the joint angles in which they are performed. That’s why, in physical therapy, we tailor isometric drills to match the needs of each patient — whether you’re a gymnast requiring deep flexibility or a football player needing powerful joint stability.
  • Improved Joint Stiffness:
    Building joint stiffness is vital for high-performance activities like running, cutting, and jumping. Isometrics play an important role in rehabilitating injuries to structures like the Achilles tendon, calf muscles, and more.

How We Use Isometrics at Cohen Health and Performance

Here’s a look at two isometric drills we commonly use in our physical therapy programs:

  1. Wall Sit with Heel Raise:
    In this variation, the patient performs a wall sit while staying high up on their toes. This position strengthens the calf and Achilles tendons in a shortened position, while also loading the patellar and quadriceps tendons — critical areas for knee health.
  2. Isometric Split Squat Hold:
    When appropriate, we add a split squat hold to further strengthen the Achilles, calf, and knee tendons. This drill also builds valuable foot and ankle stiffness, setting the foundation for more dynamic athletic movements later in rehab.

We adjust the frequency and intensity of these drills depending on how sensitive the injured tissue is, ensuring that patients progress safely through their rehab journey.

Isometric Drills Are Just One Piece of the Puzzle

While isometric exercises are powerful, they’re most effective when combined with dynamic drills — exercises where the muscles lengthen and shorten through full ranges of motion. A well-rounded physical therapy program will gradually transition patients from static strength work to dynamic, sport-specific movements to ensure a full and confident return to activity.

If you’re currently dealing with a soft tissue injury like tendinitis, a calf strain, an Achilles injury, or even an upper body strain like a pec or bicep tear, we’re here to help. Our expert team can design a customized rehabilitation plan that helps you heal effectively and get back to the activities you love.

Why We Don’t Cue“Shoulder Blades Down and Back” (And How Physical Therapy Can Help)


Growing up, my Grandma Barbara was one of my favorite people. She lived right next door in a guest apartment, and every afternoon when I came home from school, she was there to greet me. If I walked in with a bit of a slouch—maybe from lugging around a heavy backpack all day—she’d call out, “Stand up straight! Pull your shoulder blades down and back!”

I know she meant well, and I bet you’ve heard similar advice from someone in your life too.

But here’s the thing: as much as I hate to say it, Grandma was wrong.

Why “Shoulder Blades Down and Back” Can Do More Harm Than Good

In physical therapy, we see a lot of people who have been told to constantly brace their shoulder blades down and back to “fix” their posture. While that advice might sound helpful, it often causes more problems than it solves.

The reality is that posture isn’t about locking your body into one rigid position. Slouching often happens because we’re tired or trying to conserve energy—not because our shoulder blades are out of alignment. Trying to force them into place just adds unnecessary tension and restricts healthy movement.

In our physical therapy clinics in Bethesda and McLean, we frequently help active adults correct these habits so they can move better, perform stronger, and live pain-free.

Your Shoulder Blades Were Built to Move

In sport, fitness, and life, your arms need freedom to move—whether you’re lifting weights, throwing a ball, or reaching overhead. Your shoulder blades are designed to support that movement by gliding up and out—not staying pinned back.

As physical therapists, we help patients retrain how their shoulder blades move with their body instead of against it. This improves posture, relieves shoulder pain, and supports stronger performance in the gym or everyday life.

3 Physical Therapy Exercises to Improve Posture and Shoulder Function

These are three of the most effective drills we use at Cohen Health and Performance to teach better posture, improve shoulder control, and support strong, pain-free movement.

1. Core Push-Up with Serratus Activation

Most people perform push-ups with their shoulder blades pulled back and their chest puffed out—but that’s not how your body naturally moves.
In physical therapy, we coach patients to reach their chest away from the floor to activate the serratus anterior. This helps stabilize the shoulder blades in a healthy position.

2. Overhead Press with Scapular Movement

Rather than bracing the shoulder blades, we encourage our patients to let them rotate upward naturally during pressing movements. This protects the shoulder joint and mimics how your body moves in real-life tasks and athletic performance.

3. Dumbbell Pullover for Trunk Positioning

This simple but powerful drill reinforces good trunk posture while allowing natural shoulder motion. We often include this exercise in warm-ups or between sets as part of a customized physical therapy or training plan.

Rethink Posture: A Better Cue

Instead of constantly thinking “shoulder blades down and back,” try this:
Imagine a string gently pulling you up from the top of your head.
This subtle cue can reorient your posture without adding tension or compromising your shoulder mobility.

And here’s the kicker—perfect posture isn’t the goal. At Cohen Health and Performance, our physical therapy team focuses on helping you move efficiently, stay strong, and avoid injury—because those things are what actually matter.

Physical Therapy Can Help You Move Better—Not Just Stand Straighter

If you’re struggling with shoulder pain, poor posture, or feeling like your workouts are hitting a wall, we’re here to help. Our physical therapy approach is personalized, movement-based, and designed for athletes and active adults who want to keep doing what they love—without pain or limitations.

Understanding Sciatica: How Physical Therapy Can Help You Find Relief


Sciatica is one of the most common issues we treat in physical therapy, especially among active adults. It’s not just a “back problem”—sciatic nerve pain can affect your entire lower body. Why? Because the sciatic nerve is the largest and longest nerve in the human body, stretching from your lower back through the hips, glutes, hamstrings, and all the way into your lower leg and foot.

When something irritates or compresses this nerve, it can lead to pain, numbness, tingling, or weakness—anywhere along its path.

Sciatic Nerve Pain: A Highway with Potential Roadblocks

Think of your sciatic nerve like a long, busy highway. This “road” passes through many key areas of the body—your spine, hips, glutes, hamstrings, and calves. Along the way, there can be roadblocks: tight muscles, joint dysfunction, or disc-related issues that compress or irritate the nerve.

Common culprits include:

  • Disc herniations in the lower back
  • Muscle tension in the glute or piriformis region
  • Scar tissue or soft tissue restrictions further down the leg

That’s why sciatica symptoms can vary so much. You might feel pain in your lower back, or it could shoot all the way down to your foot. This is exactly why seeing a trained physical therapist is so important—we’re trained to find where the issue is actually coming from, not just treat where it hurts.

Nerves Need to Move: Why Mobility Matters

Many people are surprised to learn that nerves need to move just like muscles and joints. The sciatic nerve must be able to glide and slide as your body moves. If its mobility is restricted, you may feel sharp pain, tightness, or tingling, even when there’s no actual structural damage.

A good way to think about this is with a piece of dental floss. If you gently pull one side of the floss while holding the other still, it moves freely. But if it gets stuck somewhere along the path, tension builds. The same can happen with your nerves.

Restoring nerve mobility is a key part of an effective physical therapy plan for sciatica.

Physical Therapy Techniques for Sciatica Relief

At Cohen Health and Performance, we often use nerve gliding exercises as part of a broader physical therapy program. These movements help restore the sciatic nerve’s ability to move through the tissues without restriction, reducing pain and improving function.

Here are two examples we often prescribe:

1. Supine Nerve Glide (Lying Down)

  • Repeat for 20 reps, 1–2 times a day.

2. Standing Nerve Slide (More Advanced)

  • Repeat for 15–20 reps.

These drills are gentle and should not be painful. They’re just one piece of a complete physical therapy approach designed to restore movement and reduce irritation of the sciatic nerve.

When to Seek Physical Therapy for Sciatica

If you’re experiencing any of the following, physical therapy can help:

  • Pain that radiates down your leg
  • Numbness or tingling in your lower body
  • Difficulty sitting, standing, or walking without discomfort
  • Weakness in your leg or foot

An experienced physical therapist can assess your mobility, strength, posture, and movement patterns to find the source of the problem—not just the symptoms. From there, we create a custom treatment plan to get you back to moving pain-free.

Take Control of Your Recovery

Sciatica doesn’t have to sideline you from the activities you love. With targeted physical therapy, many active adults see significant improvements in just a few sessions. Whether your goal is to get back to the gym, return to the tennis court, or simply move without pain—physical therapy can help you get there.

How Physical Therapy Can Help You Keep Training Through Shoulder Pain


For anyone dealing with a history of shoulder pain, getting a solid upper body workout can feel like a minefield. Bench presses, overhead presses, pull-ups—many of the staple movements in strength training can feel off-limits when your shoulder isn’t moving or functioning the way it should.

But here’s the good news: physical therapy can help you get back to doing what you love in the gym—safely and effectively.

Why Overhead Movements Hurt

Many overhead exercises require a full range of motion at the shoulder. But for that to happen, the shoulder joint isn’t working alone. It relies on a coordinated effort between your shoulder blade (scapula) and your rib cage to allow your arm to move overhead without pain or compensation.

What often gets overlooked is that the rib cage needs to move 360 degrees—expanding and compressing both in the front (anterior) and back (posterior). If it can’t, your scapula can’t rotate properly, and your shoulder joint gets stuck—leading to stiffness, discomfort, or pain.

The Role of the Rib Cage in Shoulder Mobility

When you raise your arm overhead, your scapula upwardly rotates around your rib cage. But if your rib cage lacks the ability to expand and compress, especially in the upper back or chest wall, that scapular movement becomes restricted. Over time, this restriction limits your range of motion and contributes to shoulder issues.

At our physical therapy clinic, one of the first things we assess in patients with shoulder pain is how well their rib cage moves. If we find restrictions, we often start with targeted breathing and mobility drills.

Two Foundational Drills We Recommend

Here are two exercises we commonly use with patients:

1. Hooklying Overhead Reach with Breathing

This drill helps facilitate sternal movement—the rise and fall of your chest bone—which is essential for true overhead mobility. By combining this position with focused breathing, you can restore motion in the front of the rib cage.

2. Quadruped or Seated Upper Back Expansion Drills

These are designed to open up the posterior rib cage. Again, breathing is key. You’re forcing air into the areas that need more movement to help your scapula glide the way it should when you lift your arm overhead.

These exercises don’t just improve mobility—they create the preconditions for strength. Here is one example!

Build Strength in End Ranges

It’s not enough to just be mobile—you also need to be strong in those new positions. That’s one thing many people overlook. We rarely train in end-range positions, yet we expect to perform demanding lifts like pull-ups or overhead presses from those same angles.

Once mobility is restored, a good physical therapy plan includes strengthening drills that target those vulnerable ranges. This helps ensure that your body is prepared to handle the loads you’re placing on it.

Smart Modifications You Can Make in the Gym

Sometimes, even with mobility and strength gains, certain movements might still feel sketchy. That’s where smart exercise modifications come into play.

Here are two of our go-to adjustments:

1. Recline Your Bench for Overhead Pressing

Instead of pressing from a fully upright 90-degree position, try adjusting your bench to 70 degrees. This slight incline reduces the mobility demands on your shoulder but still gives you the same strength-building benefits.

2. Modify Your Pull-Up Angle

If you find yourself arching your back or “rowing” yourself to the bar during pull-ups, you’re likely compensating for a lack of mobility. Use bands, assist machines, or change your grip and angle to allow for vertical pulling without strain.

Physical Therapy: More Than Just Rehab

The beauty of physical therapy is that it’s not just for injury recovery—it’s also about performance optimization. Whether you’re a recreational lifter or a competitive athlete, working with a physical therapist can help you:

  • Identify the root cause of pain or restriction
  • Restore movement and strength
  • Learn smarter ways to train around limitations
  • Get back to enjoying your workouts without setbacks

Final Thoughts

Shoulder pain doesn’t have to be the end of your upper body training. By addressing rib cage mobility, strengthening in end ranges, and applying smart gym modifications, you can continue progressing—even with a history of pain.

If you’re tired of missing workouts or avoiding the exercises you love, consider reaching out to a physical therapy professional who understands performance. We’d love to help you move better, feel stronger, and train pain-free.
