Chronic Shoulder Pain - In a nutshell - K. Kuppens, F. Struyf, J. Nijs, N. Roussel, M. Meeus, I. Slegers, G. Hens Shoulder pain: a challenging phenomenon Mira Meeus - Filip Struyf Kevin Kuppens o.a. 25 & 26 juni 2015 Genk (www.smarteducation.be) 19 & 20 oktober 20125 Wilrijk (www.scholingrandstadwest.nl) 1 Prevalence & incidence Lifetime prevalence up to 66,7% Point prevalence 6,9 to 26% 3rd most common cause of musculoskeletal consultation in primary care Approximately 1% of adults consult a general practitioner with new shoulder pain annually. Prevalence Proportion of patients with shoulder pain Cross sectional studies Incidence New cases of shoulder pain arising in a population over a given period Prospective studies 3 Urwin et al. 1998 50% recovers within first 6 months An additional 10% during the 6 months afterwards 40% still has shoulder complaints after 1 year 80% of the total economic cost for shoulder pain Luime et al. 2004, Ryall et al. 2006, Croft et al. 1996, Van der Windt et al. 1996, Kuypers et al. 2006a,b 4 Chronic Shoulder Pain! How To Explain? Description of patients with painful shoulder syndrome Excl: fractures, surgery, cancer, shoulder-hand syndrome Chronic > Acute (1,6 x)!!! Women!!! Imaging - 66,2 % Tendinosis - 26,9 % Arthropathy - 18,5 % Bursitis - 22,3 % Normal Reference diagnosis - 75,4 % Rotator cuff syndrome - 8,7 % Unspecified Lesion - 6,3 % Frozen Shoulder - 6,3 % Cervicalgia - 2,4 % Instability - 0,8 % Arthrosis Dias et al (2008) 5 6 1
Evaluation of a (shoulder pain) patient World Health Organization - Advices framework for measuring health and disability at individual and population levels - International Classification of Functioning, Disability and Health (ICF) Didactic representation of ICF - Planetary model - Colleagues from Ghent University 7 http://www.who.int/classifications/icf/en/ 8 Dewitte et al 2014 Rotator Cuff? High density of nociceptors around the rotatorcuff insertion (supraspinatus) Glenohumeral joint? Large amount of mechanoreceptors in both the superior, middle and inferior glenohumeral ligaments; Free nerve endings in glenohumeral capsule & labrum (mainly capsulolabral & capsulohumeral) Activation and protection in case of extreme movement.

Chronic SIS (Gwilym et al.) - Referred pain - Hyperalgesia to punctuate stimuli SIS (Hidalgo-Lozano et al.) - higher n of MTrP - lower PPT s (also distant) Hyperalgesia in unilateral shoulder pain 31 Nijs, 2010 32 32 Medical diagnoses associated with central sensitization Fibromyalgia Chronic fatigue syndrome Chronic whiplash associated disorders Irritable bowel syndrome Chronic low back pain Temporomandibular dysfunction Myofascial pain sydromes Osteoarthritis Rheumatoid arthritis Headache Tennis elbow Chronic shoulder pain / impingement Algoritme recognition CS International consensus document Meeus et al. 2008, Curatolo 2001, Wand and O Connell 2008, Yunus et al. 2007, Langemark et al. 1993, Pielsticker et al. 2005, Burnstein et al. 2000, Weissman-Fogel et al. 2003 33 33 34 34 Criterion1: Disproportionate pain? Severity of pain and related disability disproportionate to the nature and extent of injury or pathology Origin Result Criterion 2: Diffuse pain distribution? One of the following options: Large pain area with a non-segmental distribution Pain varying in (anatomical) location Widespread pain Bilateral pain / mirror pain (i.e. symmetrical pain pattern) Hemilateral pain 35 35 36 36 6
- Smell - Light - Sound - Touch - Drugs - Cold / heat Criterion 3: Hypersensitivity of nonmusculoskeletal senses? Central Sensitization Inventory Measuring hypersensitivity to various stimuli: - Certain smells, such as parfums, make me feel dizzy and sick - When I want to go to bed at night, my legs feel uncomfortable and restless - Stress enhances my physical symptoms - I am sensitive to bright light http://www.paininmotion.be/csi-consensusvertaling.pdf part A only Cutoff = 40 Mayer et al.

I ve inherited weak shoulders so I m limited in what I can do - Wrong beliefs & attitudes The last time I cleaned the windows it resulted in a painful shoulder - Wrong beliefs ~ pain memory Pt: Same problem other side? Ph: Both sides grey 43 44 Take Home Messages Evaluate within a bio-psycho-social context Mind the central nervous system Careful in therapeutic communication Jump on the bandwagon?!
