Shoulder Pain and Dysfunction

Your shoulder is a complex ball-and-socket joint designed to move your arm through multiple planes of motion. Your shoulder’s diverse mobility allows you to perform a broad variety of movements and tasks, but its vast range of motion makes it the least stable joint in the human body. Because of the complex architecture of the shoulder, pain and dysfunction can stem from multiple sources, making accurate diagnosis critical to successful treatment. 

At NYDNRehab, our holistic approach to shoulder pain and dysfunction addresses more than just symptoms – we use advanced technologies and cutting-edge therapies to identify the source of your shoulder pain and eliminate it for good.

Complex Shoulder Architecture Calls for
Advanced Expertise

The shoulder complex encompasses more than just the glenohumeral joint – it involves multiple joints, muscles, fascia, ligaments, and other tissues that work together to produce, guide, and control movement. Its complex architecture makes the shoulder the most mobile joint in the human body, but its mobility comes at the cost of stability, making it prone to injury.

Joints of the shoulder complex:

  • The glenohumeral joint forms the ball-and-socket architecture that gives the shoulder its broad range of motion. 
  • The acromioclavicular joint connects the acromion of the scapula to the clavicle, allowing for limited gliding. 
  • The sternoclavicular joint attaches the clavicle to the sternum, allowing for elevation, depression, protraction, retraction, and some rotation of the shoulder girdle.
  • The scapulothoracic articulation, although not a true joint, allows the scapula to glide over the posterior thoracic wall, enabling it to tilt, rotate, and slide.

The glenohumeral joint’s shallow socket makes it vulnerable to dislocations and subluxations, especially when stabilizing structures are weak, damaged or imbalanced. Stability is provided by the rotator cuff muscles and tendons, the labrum of the glenoid, and ligaments. Fascia also plays a critical role in protecting the shoulder during physical activity, helping to guide and distribute forces via a network of elastic tension.

The rotator cuff is made up of four muscles and their tendons that compress the humeral head into the glenoid fossa, keeping it in place during movement. The infraspinatus, teres minor, subscapularis help to initiate and control shoulder rotation, while the supraspinatus aids in shoulder abduction. The rotator cuff works in concert with the deltoid, trapezius, and pectoralis major to produce smooth, coordinated motion.

Scapular stability is also important for optimal shoulder function. The scapular stabilizer muscles like the serratus anterior and trapezius hold the scapulae in position during movement, to prevent issues like winging or impingement. Multiple bursae provide shock absorption and reduce friction between tissues and bony structures. They also facilitate smooth gliding of the rotator cuff tendons beneath the acromion during arm elevation.

A complex network of neurovascular structures surround and embed the shoulder region, including the brachial plexus that innervates the arm and shoulder, and major blood vessels like the axillary artery and vein. On their path from the neck and chest to the arm, a bundle of major nerves and blood vessels passes through a narrow space beneath the clavicle called the thoracic outlet. In some cases, due to injury or repetitive stress, neurovascular bodies within the thoracic outlet can be compressed, causing pain, numbness and weakness in the arm and shoulder.

The shoulder’s complex architecture and relative instability makes it vulnerable to a broad range of injuries, such as:

  • Overuse injuries like tendinitis 
  • Dislocations and subluxations of the glenohumeral joint
  • Impingement syndromes, where nerves and blood vessels are compressed by other structures
  • Compression of the rotator tendons or the subacromial bursa
  • Rotator cuff tears
  • Tears in the glenoid labrum
  • Injury to the acromioclavicular joint, where the clavicle meets the acromion process

Without advanced knowledge of functional anatomy and the ability to visualize the shoulder in motion, it is nearly impossible to arrive at an accurate and comprehensive diagnosis based on symptoms alone. Dr. Kalika’s 20+ years of experience in diagnostic ultrasonography takes the guesswork out of shoulder diagnosis, meaning patients get the most appropriate treatment necessary for fast and effective recovery.

Accurate Diagnosis is Critical to Successful Shoulder Treatment

Diagnosis of shoulder pathology typically relies on reported symptoms, findings from a clinical exam, and testing for strength and range of motion. While that approach can help to narrow down possible causes, it may overlook critical aspects of your injury, resulting in mistreatment, prolonged pain, and excess medical costs. 

At NYDNRehab, we use high-resolution diagnostic ultrasound to view your shoulder in real time, enabling us to: 

  • Compare the injured and uninjured shoulders
  • View nerves, muscles, fascia and bones along their entire path
  • Identify fascial densifications and adhesions, and myofascial trigger points
  • Detect the exact site of nerve compression or entrapment
  • View multiple tissues and structures in a single session
  • Elicit patient feedback during the imaging session

In addition to high-resolution imaging, our ultrasound gives us capabilities for sonoelastography to gauge muscle and tendon stiffness, and superior microvascular imaging to detect early signs of healing and monitor patient progress. Your ultrasound exam takes place on your very first visit, in the comfort of our clinic. Quick and accurate diagnosis means you can begin therapy right away, with no wait time for lab results. 

New Technologies Redefine Shoulder Diagnosis and Therapy

The complexity of the shoulder region makes it difficult to identify the exact source of shoulder pain and dysfunction, and in many cases, multiple factors come into play. High resolution ultrasound imaging provides an advanced and effective diagnostic tool, especially when coupled with new technologies that dramatically enhance visualization and facilitate shoulder rehabilitation.

ShowMotion 

ShowMotion is an objective tool for joint movement analysis that uses motion tracking sensors, placed on the patient’s skin to collect data about movement quality. The patient performs a series of joint-specific movements, and the data is analyzed by ShowMotion’s proprietary software. The collected information provides valuable insights about inefficient muscle recruitment patterns, compensation patterns, and improvements in response to therapy, enabling practitioners to personalize shoulder rehabilitation. 

Neuralign Shoulder Pacemaker

The Neuralign Shoulder Pacemaker is a shoulder rehabilitation device with a kinematic sensor activated by movement. The patient dynamically interacts with the device to stimulate efficient muscle recruitment patterns, enhance movement quality, and restore optimal muscle balance during rehabilitation. The sensor provides objective data that practitioners can use to support decision-making and personalize shoulder rehabilitation. 

The Shoulder Pacemaker can be used to target common shoulder conditions: 

  • Rotator cuff disorders
  • Scapular dyskinesis
  • Shoulder instability
  • Neck pain related to abnormal shoulder movement
  • Shoulder and arm pain caused by nerve entrapment

The Shoulder Pacemaker is also a cutting-edge tool for enhancing athletic performance in shoulder-intensive sports like swimming, tennis, baseball and others. 

Scapular Ultrasound Detects Mechanical Deficiencies

High-resolution ultrasound is an important tool for observing scapular movement relative to the humeral head of the shoulder joint. Combining scapular ultrasound with ShowMotion technology provides substantial information for comprehensive shoulder rehabilitation.

The scapula compensates for shoulder instability by acting as a stable base for the glenoid fossa, to optimize positioning of the humeral head. Dynamic scapular stabilization requires well-coordinated muscle activation patterns, especially of the rotator, deltoid, trapezius and rhomboid muscles. Scapular dysfunction can increase strain on the rotator cuff and labrum, contributing to pain and instability. 

Dynamic scapular imaging lets us observe the complex interactions of the shoulder girdle kinetic chain, to pinpoint issues such as deficiencies in muscle activation, glenohumeral joint subluxation, and capsular laxity that contribute to shoulder instability. For JHS/EDS patients, scapular ultrasound can be a game-changer, ensuring they receive proper rehabilitation that enhances stability after a shoulder dislocation.

According to Dr. Kalika, shoulder pain is too often mismanaged, focusing on the rotator cuff while ignoring the scapula. Physical therapy is most effective when the structural integrity of the scapular muscles and nerves is restored. Unless the shoulder girdle/neck complex is addressed holistically, therapies targeting the rotator cuff deliver only mediocre results. However, few physical therapists know how to approach chronic shoulder blade pain and scapular dyskinesis. 

As a life-long learner, Dr. Kalika keeps up-to-date with the latest therapeutic approaches and technologies. He frequently participates in international workshops and conferences, where he rubs elbows with some of the world’s most renowned orthopedic specialists in shoulder pain and scapular dyskinesis.

We Pre-Treat Your Tissues to Optimize
Physical Therapy Results

Physical therapy is a valuable and effective tool for restoring pain-free mobility after an injury, but it does not provide a stand-alone solution. We first need to address damaged muscle and connective tissues, myofascial dysfunction, and proprioceptive deficits that can lead to reinjury. At NYDNRehab, we pretreat your damaged tissues to accelerate healing and restore biotensegrity before introducing weight-bearing activities. 

Your prehab protocol may include:

  • Multimodal shockwave therapy, to reduce pain and inflammation and stimulate tissue neogenesis
  • Extracorporeal magnetic transduction therapy (EMTT), to trigger a regenerative response in damaged tissues 
  • TECAR therapy, to restore the ionic charge of damaged cells, for faster injury healing 
  • Ultrasound-guided dry needling, to eliminate myofascial trigger points
  • Stecco fascial manipulation, to restore the functional properties of damaged fascia
  • Orthobiologic procedures, to accelerate healing at the cellular level

We monitor your response to prehab with high-resolution ultrasound, to ensure all interventions have their intended effects. Once we are satisfied that your tissues are ready to tolerate force loads, we can begin a progressive protocol of personalized, one-on-one physical therapy.

Orthobiologic Procedures Dramatically Accelerate Tissue Healing

Orthobiologic injection therapies use natural/neutral solutions, injected with precision under ultrasound guidance. The injected solutions stimulate cellular repair by either nourishing or irritating the targeted cells, triggering a regenerative response. However, orthobiologics are not a stand-alone solution – they only address tissue biology, but cannot restore functional mechanics. 

At NYDNRehab, we incorporate orthobiologics as part of our multimodal treatment strategy. Our holistic approach optimizes results and speeds recovery, so you can quickly return to play.  

Multiple factors make orthobiologic procedures at NYDNRehab superior to other clinics:

  • All procedures are guided by high-resolution ultrasound imaging, ensuring that the orthobiologic solutions precisely penetrate targeted tissues.
  • We use the highest-resolution ultrasonography available, with capabilities for sonoelastography and superb microvascular imaging. 
  • Our platelet-rich plasma (PRP) solutions are formulated with the highest and most efficacious concentration of platelets.
  • We offer multiple types of PRP, for tissue-specific results.
  • Our ultrasound-guided Prolotherapy injections enhance tissue regeneration.
  • Fascial and nerve hydrorelease procedures free up entrapped nerves and blood vessels and restore fascial gliding.

We specialize in scapular and shoulder injuries, treating swimmers, hockey players, and overhead athletes in sports like tennis, baseball and volleyball. Our unique Prolotherapy procedures for the shoulder and scapula are not available anywhere else in NYC. Read our case study to learn more about our unique approach to shoulder injuries.

Orthobiologic procedures available at NYDNRehab:

Platelet Rich Plasma (PRP)

PRP therapy uses a sample of the patient’s own whole blood, spun in a centrifuge to extract a high concentration of platelets. When injected into damaged tissues, PRP initiates tissue repair by releasing biologically active agents such as growth factors, cytokines, lysosomes and adhesion proteins. To be effective, it is critical to use the correct concentration and quality of platelets, and to follow proper isolation techniques. When administered correctly under ultrasound guidance, PRP can help to stimulate tissue repair in chronic injuries, and accelerate healing in acute injuries.

Matrix PRP

For tendon ruptures, Matrix takes PRP therapy to the next level by creating a collagenous bridge between the walls of the tear and the rest of the tendon. Matrix is a highly concentrated PRP, diluted and mixed with fibrinogen. At the injection site, the solution becomes a gel-like collagenous substance that adheres to the walls of the tear and fills the space between them, creating a fibrin matrix that helps to stabilize growth factors and attract stem cells to the treatment site.

Platelet Releasate Therapy

Platelet releasate therapy involves injecting platelet releasate – a mixture of growth factors and biomolecules – into injured muscles and tendons to promote healing. Platelet releasate works by activating leukocytes and endothelial cells, and stimulating blood vessel growth, to increase the flow of oxygen, nutrients and growth factors to the damaged tissues.

Alpha-2-Macroglobulin (A2M)

Alpha 2 macroglobulin (A2M) is a naturally occurring blood plasma protein that acts as a carrier for numerous proteins and growth factors. As a protease inhibitor, A2M reduces inflammation in arthritic joints and helps to deactivate a variety of proteinases that typically degrade joint cartilage.

Prolotherapy

Prolotherapy uses a biologically neutral solution to irritate stubborn tissues, triggering the body’s innate healing mechanisms to grow new normal tendon, ligament and muscle fibers. Prolotherapy is often used for slow-to-heal tendon and ligament ruptures, where low vascularity inhibits tissue healing.

Hyaluronic Acid Injections

Hyaluronic acid (HA) is a natural component of joint synovial fluid and fascial tissue. Its slippery gel-like properties provide lubrication that reduces friction, enabling joints, muscles and fascia to glide freely without pain. After an athletic injury, damaged fascia can become dense and sticky, losing its gliding properties. When combined with myofascial release techniques, hyaluronic acid injections can help to rehydrate fascial tissue and revitalize its functional properties. HA also supports healing by replenishing joint synovial fluid.

Interfascial Plane and Nerve Hydrodissection

The hydrodissection procedure injects a saline solution into densified fascial layers under ultrasound guidance, separating the layers and releasing entrapped nerves and blood vessels. Hydrodissection is often used in conjunction with manual fascial release and hyaluronic acid injections, to fully restore fascial integrity.

Dr. Kalika’s expertise in diagnostic ultrasound combined with Dr. Brosgol’s skill in needling procedures ensure that your orthobiologic therapy has maximal impact on the targeted tissues.

Regenerative Technologies Stimulate Cellular Repair

Regenerative therapies tap into the body’s natural healing mechanisms by stimulating the migration of stem cells, growth factors and immune cells to the treatment site, to promote the neogenesis of cells and blood vessels and accelerate the healing process. When carefully selected and combined with orthobiologics, regenerative therapies enhance their effects, and vice-versa.

Multimodal Extracorporeal Shockwave Therapy (ESWT)

Many clinics advertise shockwave therapy, but few offer radial, linear, focused and defocused shockwaves to address different tissue types. At NYDNRehab, we use multimodal ultrasound guided ESWT, to suppress pain, reduce inflammation, and promote fascia healing. ESWT helps to realign collagen fibers, promotes hydration of fascia tissues, and restores tissue gliding.

Extracorporeal Magnetic Transduction Therapy (EMTT)

EMTT transmits high energy magnetic pulses to targeted tissues that synchronize with the body’s own magnetic fields, triggering a regenerative response. EMTT waves can penetrate deep tissues to target difficult-to-reach tendons, muscles, bones and nerves

INDIBA Radiofrequency Therapy

INDIBA is a form of TECAR therapy that helps to restore the ionic charge of damaged cells, for faster injury healing and rehabilitation.

PENS

Percutaneous neuromodulation (PENS) is a therapeutic approach that uses electrical stimuli to calm and desensitize hypersensitized nerves. It involves the insertion of several filament-thin needles under ultrasound guidance into muscle tissue adjacent to the targeted nerve. PENS stimulates the nerve with varying waves of low frequency electrical current to help restore optimal neural function.

High-Intensity Laser Therapy

High-Intensity Laser Therapy (HILT) is a non-invasive treatment that uses focused laser light to promote healing, reduce pain, and decrease inflammation in a variety of musculoskeletal conditions. HILT operates via photobiomodulation, where laser light is absorbed by chromophores – light-absorbing molecules – in cellular mitochondria, triggering a cascade of biological healing processes.

Orthobiologics + Regenerative Technologies =
Optimal Tissue Healing

Regenerative therapies and orthobiologic procedures are often administered as stand-alone solutions to treat damaged tissues and pain syndromes. But while that approach may provide temporary relief, it rarely resolves the problem over the long term. By carefully selecting and combining the most appropriate therapies, we are able to harness the synergistic effects of both regenerative therapies and orthobiologics, for superior and enduring results.

Extracorporeal Shockwave Therapy (ESWT)
  • Stimulates resident tenocytes/chondrocytes/MSCs; complements PRP/BMAC’s cytokine effect.

  • Promotes collagen synthesis and angiogenesis, complementing regenerative injection effects.

Our Shoulder Physical Therapy is Customized for Every Patient

At NYDNRehab, we treat the whole patient, not just your symptoms. We never use one-size-fits-all rehab protocols or standardized recovery timelines. We believe that every injury is unique, and treatment should be based on the patient’s unique profile. 

The average physical therapist is unfamiliar with regenerative therapies and their proper use. When applied incorrectly, results can range from disappointing to disastrous. Many patients pay for regenerative procedures, only to have their effects undone by physical therapy. 

At NYDNRehab, we set a high bar for regenerative therapies and orthobiologic procedures. Guidance by high-resolution ultrasound ensures that the therapies and solutions are delivered precisely, maximizing their effectiveness. We only begin physical therapy once we are certain that your tissues are healed and ready to bear loads. 

Once we have successfully pre-treated your damaged tissues, we can begin one-on-one physical therapy to restore strength and stability, optimize mobility, and re-establish optimal neuromuscular pathways and muscle coordination patterns.

Your treatment protocol may include a combination of the following approaches:

  • Stecco fascial manipulation, to eliminate densifications and adhesions and restore fascia’s gliding properties
  • Postural restoration therapy to optimize total-body joint alignment
  • Dynamic neuromuscular stabilization (DNS) to restore developmental motor strategies
  • Integrated systems model (ISM) to optimize function and performance
  • Anatomy in motion (AIM) to enhance movement quality
  • Neurodynamics, to restore communication pathways between the brain and body
  • Conventional eccentric loading and strengthening exercises  
For athletes, your back-to-sports protocol may include sport-specific training to optimize motor skills and restore peak athletic performance. We carefully monitor patient progress with ultrasound imaging to confirm complete recovery. Click here to learn how DNS helps to improve shoulder function…

Dynamic Neuromuscular Stabilization (DNS)

Every baby is born with internal software that governs the development of functional movement patterns during early childhood. Shortly after birth, a young infant begins to follow a developmental pathway that starts with head lifting and progresses through various stages to upright walking. But developmental movement patterns learned early in life are sometimes disrupted later on due to injury, repetitive overuse or disease. 

DNS is a holistic treatment approach that taps into your primal developmental software to help restore efficient movement patterns and optimize pain-free shoulder function. Every joint in your body depends on local stabilizing muscles, tendons and ligaments, as well as coordination of both local and distal muscles, to maintain a neutral position of the humeral head in its socket. As a highly mobile joint, the shoulder relies heavily on both local and global stabilizers to assist in force transfer while protecting shoulder architecture.

The shoulder is a complex anatomical unit made up of 3 bones (scapula, clavicle and humerus), and four joints – sternoclavicular, acromioclavicular, scapulothoracic and glenohumeral. There are 17 muscles affecting the scapula, 5 muscles affecting the clavicle, and 10 ligaments holding the humeral head in its socket. To generate and transfer forces during physical activity, optimal shoulder function requires all of these structures to work together in coordinated patterns. 

Many trainers, therapists and chiropractors spend their time trying to restore the function of individual muscles, rather than focusing on coordinated movements with the shoulder in a properly centrated position. Dynamic neuromuscular stabilization helps to optimize shoulder function by correcting joint misalignment and restoring coordinated muscle recruitment patterns that have been lost over time. 

COLLAPSE

Our Advanced Therapies Quicky Restore Physical Performance

Conventional treatment of shoulder pathologies often involves rest, anti-inflammatory drugs, NSAIDs, physical therapy exercises, steroid injections and surgery. However, conventional approaches often fall short of restoring full functionality, especially for athletes and physically active patients. 

Advancements in technology are changing the game in rehabilitative medicine, enabling us to accelerate healing and restore performance at an unprecedented pace. The clinic at NYDNRehab features some of the most advanced therapeutic equipment currently available, and rarely found in private clinics.

Your shoulder therapy may involve the use of high-tech equipment:

C.A.R.E.N Computer Assisted Rehabilitation Environment

Originally developed to rehabilitate injured soldiers, this multifaceted system gives us a broad range of tools for assessment, feedback and performance enhancement. Dr. Kalka has integrated his own unique selection of technologies to optimize the ways in which C.A.R.E.N helps patients to achieve their goals.

Blood Flow Restriction Training (BFRT)

Rebuilding muscle strength while joints and connective tissues are still healing is a challenge for athletes who need to return to sport in the shortest time possible. BFRT enables you to increase muscle size and strength at much lower training volumes, to reduce stress on still-healing structures while rapidly restoring muscle performance.

Kineo Intelligent Load System

We use the Kineo intelligent loading system to create customized training and rehabilitation programs for our patients. With Kineo, we can customize variable load protocols for functional training, core training, agility drills and more. The Kineo variable resistance system lets us design a personalized variable load curve based on the needs of the individual patient.

Cryotherapy

Cold therapy has long been used for injury treatment and recovery from sports and exercise. Modern cryotherapy has replaced ice baths and ice packs with a dramatically faster and more convenient technology using nitrogen gas, directed via a specialized device to target injured tissues.

Our team of sports medicine professionals will develop a personalized treatment protocol for you, based on the specifics of your injury. In addition to restoring shoulder strength and range of motion, we use specialized technologies to retrain the brain-body connection, to restore optimal muscle recruitment patterns that are often disrupted after an injury. Neuromuscular feedback training helps our athletes to return to sport safely and confidently, with reduced risk of re-injury.

Preventing Shoulder Pain and Injuries

Any physical activity comes with built-in risks, especially if you engage in sports or occupations that place repetitive demands on the shoulder complex. But sedentary populations are also at risk for rotator cuff and shoulder injuries due to muscle deconditioning, poor joint alignment and metabolic disorders that affect shoulder function.  There are multiple steps you can take to reduce your risk shoulder pain and dysfunction:
  • Adopt a healthy lifestyle with a whole foods diet and regular exercise.
  • Eliminate sugars and processed foods from your diet, and achieve a healthy weight to prevent diabetes and metabolic disorders.
  • Be mindful of your posture and avoid rounding your shoulders, especially when using electronic devices.
  • Allow for ample recovery time between sports events and exercise bouts, especially if you are a swimmer or play overhead sports like tennis, lacrosse or baseball.
  • Do yoga or other stretching exercises to optimize mobility in the shoulder complex.
  • Take measures to manage stress and reduce chronic systemic inflammation.
  • Consider a biomechanical analysis to optimize shoulder movement and improve joint alignment.
  • Begin a balanced resistance training program to strengthen the structures that support and stabilize the shoulder complex.

    How long will it take for my shoulder injury to heal so I can get back to working out?
    Your rate of healing depends on the type and severity of your injury, and other factors unique to your condition. We personalize our treatment protocols based on your individual patient profile. Our regenerative technologies and orthobiologic procedures dramatically speed up the healing process, and ultrasound imaging confirms when your injury is fully healed.
    Will my shoulder injury heal on its own if I don't overuse it?
    While your damaged tissues will eventually heal on their own, you may develop scar tissue and muscle imbalances that reduce your shoulder mobility and stability. In many cases, collagenous connective tissues self-heal in erratic patterns that reduce their functionality. It’s best to fully rehabilitate your shoulder injury with the help of a professional.
    Why does advanced age increase the risk of shoulder injuries?
    Most people become less active over time, and many acquire metabolic disorders as they age. Lifestyle factors, including nutrition and exercise, play a role. Research shows that certain medications like statin drugs, often prescribed to older adults, are associated with a greater risk of tendinopathy. Staying active and adopting a healthy lifestyle can decrease your injury risk and improve your overall quality of life.
    How does metabolic disease increase the risk of shoulder injuries?
    Metabolic diseases like diabetes and hypertension are closely linked to obesity and other lifestyle factors. According to research, obesity increases the risk of shoulder tendinopathy due to excess mechanical stress. Metabolic disorders include chronic systemic inflammation that promotes shoulder osteoarthritis and impairs healing.

    In this instance, an athlete was originally diagnosed with minor quadriceps muscle strain and was treated for four weeks, with unsatisfactory results. When he came to our clinic, the muscle was not healing, and the patients’ muscle tissue had already begun to atrophy.

    Upon examination using MSUS, we discovered that he had a full muscle thickness tear that had been overlooked by his previous provider. To mitigate damage and promote healing, surgery should have been performed immediately after the injury occurred. Because of misdiagnosis and inappropriate treatment, the patient now has permanent damage that cannot be corrected.

    The most important advantage of Ultrasound over MRI imaging is its ability to zero in on the symptomatic region and obtain imaging, with active participation and feedback from the patient. Using dynamic MSUS, we can see what happens when patients contract their muscles, something that cannot be done with MRI. From a diagnostic perspective, this interaction is invaluable.
