Diagnosing shoulder pain conditions is a challenging area of musculoskeletal practice. Subacromial impingement syndrome (SIS) is a clinical syndrome that indicates pain and pathology involving the subacromial bursa and rotator cuff tendons within the subacromial space. The three stages of SIS are subacromial bursitis, partial thickness and full thickness rotator cuff tears. The cause of SIS is believed to be multi-factorial with both extrinsic and intrinsic factors involved in its pathogenesis. Clinicians have traditionally diagnosed SIS using a clinical examination including a subjective history followed by confirmatory clinical tests. A review of the evidence for diagnostic accuracy of clinical tests highlights that individual tests have poor diagnostic accuracy. A combination of clinical tests or a clinical examination per se may be useful at ruling out rotator cuff tears, but is less accurate at detecting rotator cuff tears when it is present. There is consensus in the literature that particular combinations of signs and clinical features may be useful in diagnosing rotator cuff tears but not for diagnosing SIS. The vast majority of research to date examining the clinical diagnosis of SIS has been focused on individual clinical tests carried out by medical practitioners in specialist and tertiary care settings. This review has established that the majority of diagnostic accuracy studies for SIS and rotator cuff tears have had poor methodological design. This exploratory study was conducted with subjects undergoing a standardized clinical examination (index test) by a physiotherapist. The decision as to which specific tests were chosen for this research was based on supporting research within the literature and the test’s actual use within the New Zealand clinical setting. This included subjective history questions, active and passive shoulder movement tests and eleven SIS tests. Subjects were referred for a diagnostic ultrasound scan immediately following the clinical examination and results from the scan stood as the criterion reference standard. Thirty eight individuals (males n=23, females n=15) with new onset shoulder pain, who met the inclusion criteria, were assessed by a participating physiotherapist. Sensitivity, specificity, positive likelihood ratios, negative likelihood ratios and respective 95% confidence intervals were calculated for all variables of the examination. Individual variables from the clinical examination were tested for their association with the diagnostic ultrasound scan reference criterion using Pearson Chi-Squared Exact test. Potential predictor variables were retained as potential predictors for use in the logistic regression analysis to determine the most accurate set of clinical examination variables for diagnosing SIS and the individual pathological stages of SIS. The results indicate that no historical, subjective or objective features from the clinical examination are accurate in diagnosing SIS or rotator cuff tears. The presence of night pain demonstrated a significant correlation (P<0.02) with the criterion reference standard for the presence of subacromial bursa fluid/bunching. Night pain and pain with overhead activity has a high sensitivity for subacromial bursa fluid/bunching being present. The absence of night pain and the absence of pain with overhead activity are two subjective phenomena from a clinical examination that are useful in ruling out subacromial bursa fluid/bunching being present. Night pain was also found to be the best predictor of subacromial bursa fluid/bunching being present (P<0.012). Male gender (P<0.034) was the best predictor of partial thickness rotator cuff tears while being 60 years of age or older (P<0.01) significantly correlated with full thickness rotator cuff tears. The Drop Arm Sign (P<0.01) and External Rotation Lag Sign (P<0.01) were significantly correlated with SIS and full thickness rotator cuff tears. Clinical tests for all three pathological stages of SIS and subacromial bursa fluid/bunching being present, had equivalent or if not greater diagnostic accuracy than previous report studies in the literature. The Hawkins-Kennedy Test and Neer Sign can be used in the primary care setting to rule out the presence of subacromial bursa fluid/bunching or SIS if the tests are negative. For mid to end stage SIS (rotator cuff tears) the Empty Can Test and Drop Arm Sign with their high sensitivity can be used to rule out rotator cuff tears especially to the supraspinatus tendon when the tests are negative. Despite the small sample size and other limitations of this study, the findings are an important addition to the current literature surrounding the diagnostic accuracy of clinical tests for SIS and rotator cuff tears. This is the first study to use physiotherapists as examiners and to be set in a primary care setting. The study is also the first to examine the diagnostic accuracy of a range of historical and subjective features from the clinical examination. The results found in the current study could be used by future studies as a starting point in the development of a clinical decision or prediction rule to assist clinicians in the diagnosis of SIS and rotator cuff tears.

Objectives: To determine the subacute effects of cervicothoracic spinal thrust/non-thrust in addition to shoulder non-thrust plus exercise in patients with subacromial pathology. Methods: This was a randomized, single blinded controlled trial pilot study. This trial was registered at ClinicalTrials.gov (NCT01753271) and reported according to Consolidated Standards of Reporting Trials requirements. Patients were randomly assigned to either shoulder treatment plus cervicothoracic spinal thrust/non-thrust or shoulder treatment-only group. Primary outcomes were average pain intensity (Numeric Pain Rating Scale) and physical function (Shoulder Pain and Disability Index) at 2 weeks, 4 weeks, and patient discharge. Results: 18 patients, mean age 43.1(15.8) years satisfied the eligibility criteria and were analyzed for follow-up data. Both groups showed statistically significant improvements in both pain and function at 2 weeks, 4 weeks, and discharge. The between-group differences for changes in pain or physical function were not significant at any time point. Discussion: The addition of cervicothoracic spinal thrust/non-thrust to the shoulder treatment-only group did not significantly alter improvement in pain or function in patients with subacromial pathology. Both approaches appeared to provide an equally notable benefit. Both groups improved on all outcomes and met the criteria for clinical relevance for both pain and function. Level of Evidence: 2b.

EFFECTS OF THORACIC SPINAL MANIPULATIVE THERAPY ON THORACIC SPINE AND SHOULDER KINEMATICS, THORACIC SPINE FLEXION/EXTENSION EXCURSION, AND PRESSURE PAIN SENSITIVITY IN PATIENTS WITH SUBACROMIAL PAIN SYNDROME By Joseph R. Kardouni, Ph.D., PT A dissertation submitted in partial fulfillment of the requirements for the degree of Doctor of Philosophy, at Virginia Commonwealth University. Virginia Commonwealth University, 2013. Major Director: Lori A. Michener, PhD, PT, ATC, Professor, Department of Physical Therapy In patients with shoulder pain, the use of manual therapy directed at the spine and shoulder have been reported to provide superior outcomes to exercise based interventions or usual care without the use of manual therapy. Clinical trials have also reported improved pain and disability after thoracic spinal manipulative therapy (SMT) as a stand-alone treatment for shoulder pain. Although clinical efficacy is reported for the use of thoracic SMT for the treatment of shoulder pain, the mechanisms underlying the clinical benefits are not well understood. This limits the directed use of SMT. The benefits could be due to changes in spine or shoulder motion or neurophysiologic mechanisms of pain modulation. Elucidating the mechanism of manual therapy will aid the directed use of thoracic SMT for treating patients with shoulder pain. The research described in chapters 3 and 4 was performed to assess the effects of thoracic SMT in patients with subacromial pain syndrome with regard to biomechanical changes at the thoracic spine and shoulder and effects on central and peripheral pain sensitivity. Subjects with shoulder impingement pain symptoms were randomly assigned to receive 1 visit of thoracic SMT or sham SMT, applied to the lower, middle, and upper (cervicothoracic junction) thoracic spine. A 3-dimensional electromagnetic tracking system was used to measure thoracic and scapular kinematics during active arm elevation, and thoracic excursion at end-range of flexion and extension pre- post-treatment. Pressure pain threshold (PPT) was measured at the painful shoulder (deltoid) and unaffected regions (contralateral deltoid and bilateral lower trapezius areas) immediately pre- and post-treatment. PPT measures at the painful shoulder were used to assess peripheral and/or central pain sensitivity, and PPT at unaffected regions measured central pain sensitivity. Patient-rated outcomes measures of pain (Numeric Pain Rating Scale-NPRS), function (Pennsylvania Shoulder Score-Penn), and global rating of change (GROC) were used to assess changes in clinical symptoms following treatment. No significant differences were found between treatment groups for the thoracic kinematics or excursion, shoulder kinematics, PPT measures, or patient-rated outcomes. No differences were noted pre- to post-treatment in either group for thoracic kinematics or excursion or PPT measures. In both groups, there was a decrease in mean scapular external rotation over time during ascending arm elevation, but the change was less than measurement error. Outcome measures of NPRS, Penn and GROC indicated clinical improvements in both groups following treatment, but there were no differences between the thoracic SMT or sham SMT groups. There were no meaningful correlations between thoracic and scapular kinematics or thoracic excursion with the outcome measures of NPRS, Penn, or GROC. There was a significant positive correlation (r=0.52 , p=0.009) between change in PPT at the lower trapezius on the unaffected side and baseline Penn scores. Biomechanically, thoracic spine extension and excursion did not change following thoracic SMT, and the SMT group had no greater changes in shoulder kinematics or patient-rated pain and function than the sham SMT group. Additionally, thoracic SMT did not improve peripheral or central pain sensitivity as measured by PPT. Furthermore, improvements in patient-rated outcomes were not found to be related to changes in thoracic spine mobility, or shoulder kinematics with SMT. The single correlation between change in PPT and baseline Penn may indicate a neurophyciologic effect of SMT in patients with higher baseline function scores, but the since no other significant relationships between PPT and outcome were seen, the implications of this finding are limited. Overall, alterations in thoracic spine mobility and pressure pain sensitivity do not appear to be responsible for improved outcomes in patients with subacromial pain syndrome. Future studies should explore the effects of SMT using other measures of thoracic spine motion and experimental pain modalities, as well as greater dosing of SMT over a longer follow-up.

This diploma thesis is focused on the observation of influence of Vojta's reflex locomotion on the activity of shoulder girdle's muscles at patients with the subacromial impingement syndrome. We examined ten patients with the subacromial impingement syndrome as well as twenty asymptomatic individuals. We evaluated the impact of just one Vojta's reflex locomotion therapy on the activity of muscles using the Method of the Surface Electromyography. At the same time we evaluated if the reaction on the therapy had some impact on measured values. The therapy always took at least time necessary to obtain any reaction of each of the individuals, although the maximum limit of the therapy was 32 minutes. The impact of Vojta's reflex locomotion therapy had not statistical importance with regard on changes of muscle activity after and before the therapy, with regard on the symmetry of muscle activity, as well as the difference of beginning of activation of every muscle before and after the therapy. The statistical importance was influenced just by the corporeal disposition of every measured individual, which was observed on the timing. The influence of the corporeal disposition on the average measured values with regard of the left - right side symmetry has no statistical importance. The statistical...

Abstract Aim: The aim of this study was to investigate if treatment with “dry needling” in myofascial triggerpoints (MTrPs) in the rotatorcuff muscles may affect impingement symptoms such as pain during provocative tests, shoulder mobility, and function. The research questions were: Does the value of pain change on the Visual Analog Pain Scale (VAS) between before and after treatment? Do the positive provocative tests for impingement change between before and after treatment? Does the active shoulder mobility change between before and after treatment? Does the self-rated function change between before and after treatment? Method: The study was a prospective randomized intervention study and 19 persons with impingement symptoms (mean ± standard deviation; 58 ± 18 years, and shoulder pain duration 3.9 ± 1.6 months) were randomized into two groups. The groups were tested before, directly after and 3 weeks after treatment. The intervention group was treated twice, with a week in between, with “dry needling” in MTrPs. The control group was also treated on two occasions but was instead given a superficial needle in the infraspinatus muscle. All subjects were treated by the same physiotherapist. Pain was evaluated on the VAS when subjects performed active shoulder flexion before and after treatment. Provocative tests for shoulder impingement (Neer sign, Hawkins-Kennedy test and Jobe test) as well as range of motion tests were performed before, after and three weeks after treatment. The frequencies of positive/negative provocative tests were presented. Shoulder function was evaluated with the QuickDASH questionnaire. Significance level p≤0.05 was used in the study and a tendency was identified between 0.05 ≤ p &lt; 0.1. Results: There was a tendency (p=0.086) with decreased pain (VAS) in the intervention group after the treatment. Among the impingement tests only significant improved results was observed for Neer sign test three weeks after the treatment (p=0.025) No significant difference could be seen on the active shoulder mobility between before and after the treatment. The perceived function in the intervention group, measured with the Quick DASH questionnaire, showed a tendency (p=0.086) towards a better function. Conclusions: The study showed a tendency towards that”dry needling”  in MTrPs may affect impingement symptoms such as pain and function. The provocative tests for shoulder impingement, Neer sign, showed a significant decrease in pain after treatment. More studies with larger population is needed to make a statement about the effect of “dry needling” in MTrPs as a treatment for shoulder impingement symptoms. / Sammanfattning Syfte och frågeställningar: Syftet med studien var att undersöka om behandling med ”dry needling” (intramuskulär nålstimulering) i myofasciella triggerpunkter (MTrPs) i rotatorcuffmuskulaturen kan påverka impingementsymptom såsom smärta vid provokationstester, axelledsrörlighet och funktion. Frågeställningarna var: Förändras smärtskattning på visuell analog skala(VAS) vid aktiv axelflexion efter jämfört med före behandling? Förändras de positiva provokationstesterna för impingement efter jämfört med före behandling? Förändras den aktiva axelledsrörligheten efter jämfört med före behandling? Förändras den självskattade funktionen efter jämfört med före behandling? Metod: Studien var en prospektiv randomiserad interventionsstudie, 19 forskningspersoner (fp) med impingementsymptom, (medelålder 58 ± 18 år, besvärsdurationens medeltid 3.9 ± 1.6 mån), randomiserades till två grupper. Grupperna undersöktes före, direkt efter och tre veckor efter avslutad behandling. Interventionsgruppen behandlades vid två tillfällen, med en veckas mellanrum, med ”dry needling” i MTrPs medan kontrollgruppen vid två tillfällen istället fick en ytlig akupunkturnål i m infraspinatus. Behandlingen av alla fp utfördes av en och samma fysioterapeut. Smärta utvärderades med (VAS) vid aktiv axelflexion direkt före och efter behandling. Provokationstester (Neer sign, Hawkins-Kennedy test och Jobe test) samt rörlighetsmätning utfördes före, efter och tre veckor efter avslutad behandling. Frekvensen positiva/negativa provokationstesttest summerades. Funktionen utvärderades med frågeformuläret QuickDASH. Signifikansnivå p&lt; 0.05 används i studien och en tendens identifierades mellan 0.05 ≤ p &lt; 0.1. Resultat: Det fanns en tendens (p=0.086) till minskad smärta (VAS) i interventionsgruppen efter jämfört med före behandling. Bland impingementtesterna sågs enbart ett signifikant förbättrat resultat för Neers sign tre veckor efter avslutad behandling jämfört med före behandling (p=0.025). Ingen signifikant skillnad kunde ses gällande rörligheten före och efter behandling. Den upplevda funktionsförmågan mätt med frågeformuläret QuickDASH visade en tendens (p=0.086) mot bättre funktion i interventionsgruppen. Slutsats: Studien har visat tendenser på att ”dry needling” i MTrPs kan påverka impingementsymptom såsom minskad smärta och bättre självskattad funktion efter behandling jämfört med före. Impingementtestet Neer sign visade en signifikant minskad smärta efter behandling. Fler studier med större grupper, större ålderspann och längre behandlingstid behövs för att kunna uttala sig om effekten av ”dry needling” i MTrPs som behandlingsmetod vid impingementsymptom i axeln. / <p>Fristående kurs i Idrottsvetenskap inriktning idrottsmedicin 2013-2015</p>
