Table 11 contains the descriptive data from the professional baseball pitchers and elite junior tennis players.33 More research including additional subject populations is needed to outline the total rotation ROM concept further. In a series of 10 patients with traditional impingement signs and anterior-based pain presentations, Struhl23 arthroscopically confirmed contact between the fragmented undersurface of the rotator cuff tendons and the anterosuperior labrum during the Hawkins impingement test, viewed from a posterior arthroscopic portal. 365 0 obj <>/Filter/FlateDecode/ID[<4A4E3F3BA7CB234F94F7D87A37576B23><7ABB4B68D9A2F54499B0AE6B22F14F8A>]/Index[343 46]/Info 342 0 R/Length 104/Prev 66714/Root 344 0 R/Size 389/Type/XRef/W[1 2 1]>>stream 18 Walch et al 19 4 Rehabilitation of Adhesive Capsulitis In contrast, we tested 117 elite male junior tennis players.33 In these tennis players, significantly less IR ROM was found on the dominant arm (45 degrees versus 56 degrees), as well as significantly less total rotation ROM on the dominant arm (149 degrees versus 158 degrees). Patients presenting with a limitation in IR ROM who have grade II translation should not have posterior glide accessory techniques applied to increase IR ROM due to the hyper-mobility of the posterior capsule made evident during this important passive clinical test. Dr. Sameer Nagda, MD is an Orthopedic Surgery Specialist in Alexandria, VA. Peak forces against the acromion were measured in a range of motion (ROM) between 85 degrees and 136 degrees of elevation.8 This position is a functionally important one for daily activities, sport-specific movements,9,10 and situations commonly encountered on a job as well. Additionally, with this technique a protracted scapular position can be utilized to increase the activation of the serratus anterior muscle30,31; several studies have identified decreased muscular activation of this muscle in patients diagnosed with glenohumeral impingement and instability.25,32. adobe:docid:indd:d426ab4c-3564-11de-9476-80770b4263da hb```f``Z ,@Q=wC%EsJ(ix~hK- & D!& iYp)821!,@4r10@t77## tQxAFf*v *: Adobe InDesign CC 13.0 (Macintosh) Patients presenting with a limitation in IR ROM who have grade II translation should not have posterior glide accessory techniques applied to increase IR ROM due to the hyper-mobility of the posterior capsule made evident during this important passive clinical test. In all types of impingement listed above, scapular dysfunction either can be the underlying cause or can greatly exacerbate the impingement process with altered scapular kinematics in patients with both rotator cuff instability and impingement.2426 Initial rehabilitation begins with the protection of the rotator cuff from stress but not function. Remember this number: 25%. Re-establish muscular 12) can be initiated to provide muscular co-contraction in a functional position. 1) The increase in Horizontal Abduction (elbow moving behind shoulders) creates a pinching/closing angle fulcrum of the deep structures of the posterior shoulder To determine the tightness of the posterior glenohumeral joint capsule, an accessory mobility technique to assess the mobility of the humeral head relative to the glenoid is recommended. When this occurs, the bones in the shoulder pinch down on the tendons and cause shoulder impingement. / The examiner then feels for translation of the humeral head along the glenoid face. Note the inherent means of scapular stabilization in both methods that are necessary to optimize the value of the stretching procedure. Results showed even submaximal contractions increased perfusion during all 1-minute contractions; but they also produced a postcon-traction latent hyperemia following the muscular contraction. shoulder internal impingement non-operative guidelines The following internal impingement guidelines were developed by HSS Rehabilitation and are categorized into five phases with the The rotator cuff must be protected against mechanical compression by the overlying coracoacromial arch or posterior glenoid; this can be done by modifying ergonomic, sport-specific postures and movement patterns as well as those related to activities of daily living (ADL). Impingement of the undersurface of the rotator cuff on the posterosuperior glenoid labrum may be a cause of painful structural disease in the athlete practicing sports with overhead movement. Stage Iedema and hemorrhageresults from the mechanical irritation of the tendon; this is caused by impingement incurred from overhead activity. For this exercise, all you need is a blank wall and a towel.

Download a Guide to our Shoulder-Saving Procedures. Manual techniques allow the clinician to interface directly with the patients scapula to bypass the glenohumeral joint and permit repetitive scapular exercise without inducing undue stress to the rotator cuff in the early phase. 0 Solem-Bertoft et al28 has shown the importance of scapular retraction posturing by reporting a reduction in the width of the subacromial space when comparing scapular protraction posturing to scapular retraction. endstream endobj 3 0 obj <> endobj 5 0 obj <>/ExtGState<>/Font<>/ProcSet[/PDF/Text/ImageC]/XObject<>>>/TrimBox[0.0 0.0 612.0 792.0]/Type/Page>> endobj 6 0 obj <>/Font<>/ProcSet[/PDF/Text/ImageC]/XObject<>>>/TrimBox[0.0 0.0 612.0 792.0]/Type/Page>> endobj 7 0 obj <>/ExtGState<>/Font<>/ProcSet[/PDF/Text]/XObject<>>>/TrimBox[0.0 0.0 612.0 792.0]/Type/Page>> endobj 8 0 obj <>/ExtGState<>/Font<>/ProcSet[/PDF/Text]>>/TrimBox[0.0 0.0 612.0 792.0]/Type/Page>> endobj 9 0 obj <>/ExtGState<>/Font<>/ProcSet[/PDF/Text]>>/TrimBox[0.0 0.0 612.0 792.0]/Type/Page>> endobj 10 0 obj <>/ExtGState<>/Font<>/ProcSet[/PDF/Text]>>/TrimBox[0.0 0.0 612.0 792.0]/Type/Page>> endobj 11 0 obj <>/ExtGState<>/Font<>/ProcSet[/PDF/Text]/XObject<>>>/TrimBox[0.0 0.0 612.0 792.0]/Type/Page>> endobj 41 0 obj <>stream 0 uuid:1670d8ce-a002-1740-aa91-1bca29250ba9 Adobe PDF Library 15.0 Additionally, with this technique a protracted scapular position can be utilized to increase the activation of the serratus anterior muscle30,31; several studies have identified decreased muscular activation of this muscle in patients diagnosed with glenohumeral impingement and instability.25,32 One area that has received a great deal of attention in the scientific literature is the presence of an IR ROM limitation, particularly in the overhead athlete with rotator cuff dysfunction.33,34 To determine the course of treatment for the patient with limited IR ROM, clinical assessment strategies must be employed to determine whether the limitation and subsequent treatment strategy to address the limitation in glenohumeral joint IR should be targeted for the muscletendon unit or the posterior capsule. 343 0 obj <> endobj Shoulder disorders are very common in clinical practice. %PDF-1.6 % This is meant to be held for a longer period of time so the inert posterior capsule can also make the appropriate changes.Visit our website: http://themuscledoc.com/Check out my Tweets: https://twitter.com/the_muscle_docLike us on Facebook: https://www.facebook.com/themuscledoc/Follwow me on Instagram: https://www.instagram.com/the_muscle_doc/Check out our videos: https://www.youtube.com/channel/UCzXqjJB345oP7LqrTUB52XQCome see us at: The Muslce Doc241 Polaris Avenue,Mountain View CA, 24043P: (408) 966-7690 Direct visualization during arthroscopy revealed undersurface tears of the rotator cuff due to the contact that occurs between the anterosuperior labrum and undersurface of the rotator cuff, similar to that described by Walch et al19 in posterior impingement. Secondary Impingement The presence of anterior translation of the humeral head with maximal ER and 90 degrees of abduction, which has been confirmed arthroscopically during the subluxation-relocation test, can produce mechanical rubbing and fraying on the undersurface of the rotator cuff tendons. One study highlights the importance of early submaximal exercise to increase local blood flow. Your doctor may recommend non-operative or operative treatments to treat internal impingement of the shoulder. This technique is most often referred to as the posterior load and shift or posterior drawer test.35,36 Figure 1-3 shows the recommended technique for this examination maneuver whereby the glenohumeral joint is abducted 90 degrees in the scapular plane (note the position of the humerus 30 degrees anterior the coronal plane). Paley et al22 also published a series on arthroscopic evaluation of the dominant shoulder of 41 professional throwing athletes. application/pdf Neers Stages of Impingement Sitting or standing up straight, pinch shoulder blades together as if pinching a peanut between them. Stage : consists of stiffness and difficulty in warming up, but no complaints of pain. Full-thickness tears of the rotator cuff, partial-thickness tears of the rotator cuff, biceps tendon lesions, and bony alteration of the acromion and acromioclavicular joint may be associated with this stage.12 In addition to bony alterations that are acquired with repetitive stress to the shoulder, the native shape of the acromion is of relevance. Primary impingement, also known as compressive disease or outlet impingement, is a direct result of compression of the rotator cuff tendons between the humeral head and the overlying anterior third of the acromion, cora-coacromial ligament, coracoid, or acromial-clavicular joint.1,2 The physiologic space between the inferior acromion and superior surface of the rotator cuff tendons is termed the subacromial space. Call for information or to book an appointment to see us in person. Paley et al22 also published a series on arthroscopic evaluation of the dominant shoulder of 41 professional throwing athletes. In a series of 10 patients with traditional impingement signs and anterior-based pain presentations, Struhl23 arthroscopically confirmed contact between the fragmented undersurface of the rotator cuff tendons and the anterosuperior labrum during the Hawkins impingement test, viewed from a posterior arthroscopic portal. Biomechanical analysis of the shoulder has produced theoretical estimates of the compressive forces against the acromion with elevation of the shoulder. Burkhart et al34 have termed this IR loss GIRD-glenohumeral internal rotation deficitand define it as a loss of internal rotation of 20 degrees or more compared with the contralateral side. However, patients with primary impingement often present with underlying capsular hypo-mobility and are definite candidates for specific mobilization techniques to improve glenohumeral joint arthrokinematics. However, patients with primary impingement often present with underlying capsular hypo-mobility and are definite candidates for specific mobilization techniques to improve glenohumeral joint arthrokinematics. Range-of-Motion Exercises. Specific changes in the program will be made by the physician as appropriate for the individual patient. Note: All progressions are approximations and should be used as a guideline only. Modalities such as electrical stimulation, ultrasound, and iontophoresis can be applied to promote improved blood supply and decrease pain levels; however, a clearly superior modality or sequence of modalities for the early management of tendon pathology in the human shoulder is lacking. xmp.did:048011740720681188C6C22164859945 If you would like help relieving your shoulder pain, our team of highly-trained therapists can alleviate the pain with personalized 1:1 physical therapy sessions. 503 0 obj <>/Filter/FlateDecode/ID[<134431657913AA4EB46C7748850DE83C>]/Index[487 27]/Info 486 0 R/Length 91/Prev 266624/Root 488 0 R/Size 514/Type/XRef/W[1 3 1]>>stream 3 Rehabilitation of Macro-Instability The range of motion is small. Recent research has compared the effects of the cross-arm stretch to the sleeper stretch in a population of recreational athletes, some with significant glenohumeral IR range of motion deficiency.56 Four weeks of stretching produced significantly greater IR gains in the group performing the cross-body stretch as compared with the sleeper stretch. Posterior Impingement of the shoulder is a very common malady of overhead athletes of all disciplines and is something that can be easily managed when identified. Figure 13 Posterior glenohumeral joint translation test at 90 degrees of abduction in the scapular plane. Due to the increased humeral head translation, the biceps tendon and rotator cuff can become impinged secondary to the ensuing instability.13,14 A progressive loss of glenohumeral joint stability is created when the dynamic stabilizing functions of the rotator cuff are diminished from fatigue and tendon injury.14,17 The effects of secondary impingement can lead to rotator cuff tears as the instability and impingement continue.3,14 Jensen etal27 studied the effects of submaximal [5 to 50% maximum voluntary contraction (MVC)] contractions in the supraspinatus tendon measured with laser Doppler flowmetry. These stretches can be used in a proprioceptive neuromuscular facilitation (PNF) contractrelax format or following a lowload prolonged stretchtype paradigm to facilitate the increase in ROM.54,55 Figures 17 and 18 are examples of home stretches given to patients to address IR ROM deficiency. Traditional impingement involves the superior or bursal surface of the rotator cuff tendon or tendons and typically produces anterior and anterolateral pain distributions.20 Conversely, individuals presenting with posterior shoulder pain brought on by positioning of the arm in 90 degrees of abduction and 90 degrees or more of ER, typically from overhead positions in sport or work activities, may be considered as potential candidates for undersurface impingement. %PDF-1.5 % Unidirectional posterior shoulder instability is much less common than anterior instability, however it should be strongly suspected in those high risk group of athletes with posteroir shoulder pain and/or clicking. Phase I Protection Phase (weeks 0-4): Review videos for shoulder immobilizer and passive ROM (Codmans pendulum, passive flexion). Bilateral comparison of IR ROM is taken with careful interpretation of isolated glenohumeral motion. There can be additional harm caused by the posterior deltoid if the rotator cuff is not functioning properly. Activation of the serratus anterior and lower trapezius force couple is imperative to enable scapular upward rotation and stabilization during arm elevation.29 Rhythmic stabilization applied to the proximal aspect of the extremity progressing to distal with the glenohumeral joint in 80 to 90 degrees of elevation in the scapular plane (Fig. Adobe InDesign CC 13.0 (Macintosh) Impingement of the undersurface of the rotator cuff on the posterosuperior glenoid labrum may be a cause of painful structural disease in the athlete practicing sports with overhead movement. Hence, in guiding patients through the rehabilitation process, an accurate ROM measurement and informed decision making are essential to the clinician. %%EOF PJT,*$(dsJE5N i> *A%QL&1+ul|n0\IpLxm! Primary impingement, also known as compressive disease or outlet impingement, is a direct result of compression of the rotator cuff tendons between the humeral head and the overlying anterior third of the acromion, cora-coacromial ligament, coracoid, or acromial-clavicular joint.1,2 The physiologic space between the inferior acromion and superior surface of the rotator cuff tendons is termed the subacromial space. 1 Observed in younger, more athletic patients, it is a reversible condition with conservative physical therapy. This occurs from repeated episodes of mechanical inflammation and can include thickening or fibrosis of the subacromial bursae. Rehabilitation ofShoulder Impingement:Primary, Secondary,and Internal It is important to use consistent measurement techniques when documenting ROM of glenohumeral joint rotation. Lucas7 estimated this force at 10.2 times the weight of the arm. Hold 5 seconds and repeat 10 times, Standing in a doorway with hand holding onto doorframe just below shoulder height, turn body away from your arm until a stretch is felt in the chest. Additionally, Crockett et al45 have shown unilateral increases in humeral retroversion in throwing athletes, which would explain the increase in ER with accompanying IR loss. Phase II Motion Phase (weeks 5-8): Review videos for active ROM,overhead pulley and isometric strengthening (flexion, extension,abduction, external 7,10-13 Subacromial impingement syndrome is the most commonly diagnosed shoulder pathology within the general population 14-16 and is also a frequent pathology seen in baseball pitchers. A type III or hooked acromion was found in 70% of cadaveric shoulders with a full-thickness rotator cuff tear, whereas a type I acromion was only associated with 3% of this group.11 Additionally, in a series of 200 clinically evaluated patients, 80% with a positive arthrogram confirming a full-thickness rotator cuff tear had a type III acromion.12 One study highlights the importance of early submaximal exercise to increase local blood flow. Dull ache in the front or side of the shoulder. Full-thickness tears of the rotator cuff, partial-thickness tears of the rotator cuff, biceps tendon lesions, and bony alteration of the acromion and acromioclavicular joint may be associated with this stage.12 In addition to bony alterations that are acquired with repetitive stress to the shoulder, the native shape of the acromion is of relevance. Neer1,2 has outlined three stages of primary impingement as it relates to rotator cuff pathology. endstream endobj startxref Stage: hallmarked by the complaint of pain during the late cocking phase of the throwing cycle. In addition to the early scapular stabilization and submaximal rotator cuff exercise, ROM and mobilization may be indicated based on the underlying mobility status of the patient. 598 0 obj <>stream Clinical application of the total rotation ROM concept is best demonstrated by a case presentation of a unilaterally dominant upper-extremity sports athlete. In elite tennis players, the total active rotation ROM can be expected to be up to 10 degrees less on the dominant arm before an extensive clinical treatment to address IR ROM restriction would be recommended or implemented. Stage Iedema and hemorrhageresults from the mechanical irritation of the tendon; this is caused by impingement incurred from overhead activity. Hence, despite bilateral differences in the actual IR and/or ER ROM in the glenohumeral joints of baseball pitchers, the total arc of rotational motion should remain the same. This can occur from repetitively moving the shoulder into a stressful or suboptimal positioncommon in climbing. San Francisco, CA 94123, United States. The typical age range for this stage of injury is 25 to 40 years. A type III or hooked acromion was found in 70% of cadaveric shoulders with a full-thickness rotator cuff tear, whereas a type I acromion was only associated with 3% of this group.11 Additionally, in a series of 200 clinically evaluated patients, 80% with a positive arthrogram confirming a full-thickness rotator cuff tear had a type III acromion.12, Impingement or compressive symptoms may be secondary to underlying instability of the glenohumeral joint.13,14 Though relatively common knowledge today, this concept was not well understood or recognized in the medical community even through the mid- to late 1980s. The primary symptoms and physical signs of this stage of impingement or compressive disease are similar to the other two stages and consist of a positive impingement sign, painful arc of movement, and varying degrees of muscular weakness.2 How do you repair it? posterior shoulder pain, especially in the late cocking phase. To have a numerical representation of the total rotation range of motion available at the glenohumeral joint, the glenohumeral joint IR, and ER ROM measure are added together. Research by Kibler et al47 and Roetert et al48 has identified decreases in the total rotation ROM arc in the dominant extremity of elite tennis players correlated with increasing age and number of competitive years of play. The straight posterior force compresses the humeral head into the glenoid because of the anteverted position of the glenoid; this would inaccurately lead to the assumption by the examining clinician that limited posterior capsular mobility is present. In addition to the early scapular stabilization and submaximal rotator cuff exercise, ROM and mobilization may be indicated based on the underlying mobility status of the patient. A large spectrum of mobility can be encountered when treating the patient with glenohumeral impingement. Additionally, Crockett et al45 have shown unilateral increases in humeral retroversion in throwing athletes, which would explain the increase in ER with accompanying IR loss. Manual techniques allow the clinician to interface directly with the patients scapula to bypass the glenohumeral joint and permit repetitive scapular exercise without inducing undue stress to the rotator cuff in the early phase. Each utilizes an inherent anterior hand placement; this gives varying degrees of posterior pressure to minimize scapular compensation and to provide a check against anterior humeral head translation during the IR stretch.
