📚The elbow is composed of the humeroulnar, humeroradial (shown here) and proximal radioulnar joints.

🔎The humeroradial and humeroulnar joints allow the elbow to move through approximately 150 degrees of flexion (bending) and full extension (straightening).

🧠The humeroradial joint is made up of the concave radial head and convex capitulum portion of the humerus bone.

✅In the elbow section of the app, you will find three elbow rehab programs for tennis elbow, golfers elbow, and triceps tendinopathy.

📚The term shoulder impingement was traditionally used to describe shoulder pain that was thought to result from the rotator cuff tendons or subacromial bursa being “pinched” beneath the acromion.

🔎People with subacromial pain syndrome often experience pain when lifting the arm out to the side or overhead, with symptoms commonly occurring during the painful arc shown in the first image of today’s post.

🧠Today, many clinicians prefer the term subacromial pain syndrome because research has shown that structural “impingement” alone does not fully explain why symptoms develop. Many people have narrowing of the subacromial space or rotator cuff changes without any pain, while others develop symptoms despite minimal structural findings. Instead, pain is thought to result from a combination of factors including tendon loading capacity, muscle function, movement patterns, and nervous system sensitivity.

💪The good news is that most people improve with a progressive rehabilitation program focused on restoring shoulder strength, improving tolerance to movement, and gradually returning to overhead activities.

✅The app contains a comprehensive, 3-phased program for subacromial pain syndrome that will guide you through the rehabilitation process. Click the link below to access this program.

Hi everyone! A new video on exercises to help improve knee stability is available here in the app. Here is a link for the video.

📚The hamstring muscles (biceps femoris, semimembranosus, and semitendinosus) run along the posterior thigh and act to flex (bend) the knee and extend the hip.

🔎Because the hamstrings serve as antagonists to the quadriceps, they are vitally important in terms of knee stability and overall lower extremity control.

🏋🏼‍♂️However, most people have a tendency to pick exercises that target the quads (also very important) and neglect the hamstrings.

✅The app includes a hamstring injury rehab program that teaches you how to heal and strengthen the hamstrings after an injury. Click the link below to access the program.

👉Soft tissue mobilization works by stimulating mechanoreceptors in muscle and fascia, which can decrease nociceptive signaling and reduce protective muscle guarding.

🔎This neurophysiological response, combined with improved local blood flow and tissue elasticity, often helps lower pain sensitivity and restore freer, more efficient movement.

🧠Soft-tissue mobilization of the lumbar extensor muscles (erector spinae group), which run along your lower spine can be a helpful strategy for reducing low back pain. In this video, I show a technique using a peanut massager tool, which works well for targeting the lumbar extensor muscles.

✅More techniques like this and other mobility and strengthening exercises can be found in the low back pain program here in the app.

👉Scapulothoracic mobilizations are a valuable manual therapy technique for improving movement of the shoulder blade and relieving pain around the shoulder and mid back.

🔎In this technique, the patient lies on their side while the clinician reaches their fingers beneath the medial border of the scapula to gently lift it away from the rib cage. This helps mobilize the scapulothoracic joint — the interface between the scapula and the thoracic wall — which often becomes stiff in people with shoulder or upper back pain.

🧠Restoring mobility at this region allows the scapula to move more freely during overhead and reaching motions, reducing compensatory stress on the glenohumeral joint, rotator cuff, and surrounding soft tissues. By improving scapular motion and control, this mobilization can help decrease pain, enhance posture, and restore proper mechanics for functional movements like reaching, lifting, and pressing.

✅If you experience pain around the shoulder blade or upper back, restricted scapular movement may be a contributing factor. Manual mobilization, combined with targeted exercises for scapular control and thoracic mobility, can be an effective approach to restoring comfort and function.

📚The interphalangeal (IP) joint is the only joint between the two bones of the thumb: the proximal and distal phalanges. It functions as a simple hinge joint, allowing the thumb to bend (flexion) and straighten (extension).

🧠Although it has a relatively small range of motion compared to the other thumb joints, the IP joint plays an important role in precision grip. Every time you button a shirt, write with a pen, text on your phone, or pick up a small object, the IP joint helps position the thumb with accuracy.

🔎The primary muscle responsible for bending the joint is the flexor pollicis longus (FPL), while straightening is produced mainly by the extensor pollicis longus (EPL). Together, these muscles provide the fine motor control needed for everyday tasks.

✅Pain, stiffness, or arthritis at the thumb IP joint can make even simple activities surprisingly difficult. Maintaining mobility and strength throughout the thumb can help preserve hand function as we age.
