Brief summary

In this prospective study, subjects older than 55 years with a degenerative asymptomatic rotator cuff tears will be followed for a period of 2 years. After testing, a symptom registration form will be filled in every 3 months. The test moment consists of pain measurements (pain pressure thresholds and conditioned pain modulation), biomechanical measurements (strength (including hand grip strength), range of motion, ultrasound (while measuring electromyographic activity) and shear wave elastography) and psychosocial measurements (psychosocial questionnaires).

Detailed description

In this prospective study, the aim is to determine the risk factors for developing a symptomatic rotator cuff (RC) tear. It is still unknown why some patients with a RC tear develop complaints and others do not. Better understanding of the etiological factors that underlie RC pathology will increase the efficacy of early clinical intervention. A prospective study with a minimum of 2 year follow-up will be conducted. Biomechanical, psychosocial and painrelated factors will be screened as possible risk factors. We hypothesize that negative psychosocial factors and biomechanical impairments will be risk factors for an asymptomatic tear to become symptomatic over time.

Design outcomes

Primary

MeasureTime frameDescription
Pressure Pain Thresholds (PPT)Baseline - 2 year if remaining asymptomatic or at moment of becoming symptomaticPPTs will be measured on three local locations around the shoulder (supraspinatus, infraspinatus and posterior deltoid). Additionally, two more distal PPTs will be measured (erector spinae and triceps surae).
Acromiohumeral distance (AHD)Baseline - 2 year if remaining asymptomatic or at moment of becoming symptomaticThe AHD is the shortest linear distance between the inferior edge of the acromion and the superior edge of the humeral head. This will be measured during rest and during muscle activity.

Secondary

MeasureTime frameDescription
Conditioned Pain Modulation (CPM)Baseline - 2 year if remaining asymptomatic or at moment of becoming symptomaticThe conditioning stimulus will comprise of immersion of the foot until the proximal ankle (level of the malleoli) in a hot circulating water bath of 45.5°C during 1 minute. The test stimulus will comprise of pressure pain threshold (PPT) assessments (as described above) before and after completion of the conditioning stimulus.
Central Sensitization Inventory (CSI)Baseline - 2 year if remaining asymptomatic or at moment of becoming symptomaticThe CSI measures the participant's Central Sensitization Syndrome related symptoms. The higher the score, the more signs of central sensitization are present.
Tampa Scale for Kinesiophobia (TSK)Baseline - 2 year if remaining asymptomatic or at moment of becoming symptomaticThe TSK evaluates the general pain related fear of movement. The higher the score, the higher the pain related fear.
Short Form-36 (SF-36)Baseline - 2 year if remaining asymptomatic or at moment of becoming symptomaticThe SF-36 evaluates the general health and well-being or quality of life. Contains a physical and mental component score. A higher score expresses a better health condition.
Shoulder Pain and Disability Index (SPADI)Baseline - 2 year if remaining asymptomatic or at moment of becoming symptomaticThe SPADI evaluates the pain and restrictions in activities. The higher the score, the worse the symptoms.
Depression, anxiety and stress scale (DASS-21)Baseline - 2 year if remaining asymptomatic or at moment of becoming symptomaticDASS-21 evaluates the depression (7 items); anxiety (7 items) and stress (7 items). The score will be multiplied by 2 to have a comparable score with the DASS-42.
Clinical test - strengthBaseline - 2 year if remaining asymptomatic or at moment of becoming symptomatic45° scapular elevation - external rotation - internal rotation - hand grip strength
Insomnia Severity Index (ISI)Baseline - 2 year if remaining asymptomatic or at moment of becoming symptomaticSeven questions to ask for sleep problems.
General Self-Efficacy Scale (GSES)Baseline - 2 year if remaining asymptomatic or at moment of becoming symptomaticThe GSES measures (10 statements) how a person deals with stressors/difficult situations in life. The scale is about a person's self-confidence that his or her actions are responsible for successful outcomes or, in other words, that one has control over challenging demands imposed by the environment.
Electromyographic activity (EMG)Baseline - 2 year if remaining asymptomatic or at moment of becoming symptomaticElectromyographic activity will be measured during AHD measurement in rest and during activity. The amplitude of the EMG activity from the three parts of the deltoid (anterior, middle and posterior part) will be obtained. The unit is volt. EMG activity will be expressed as percentage of the MVIC (maximal voluntary isometric contraction).
Shear Wave Elastography (SWE)Baseline - 2 year if remaining asymptomatic or at moment of becoming symptomaticThis is a non-invasive and real time assessment of tissue mechanical properties that measures the elasticity of the muscles/tendons. The higher the shear modulus/young modulus/shear wave speed, the higher the stiffness. SWE assessment will be done for the followings muscles: supraspinatus, infraspinatus, anterior and posterior deltoid.
Supraspinatus muscle thicknessBaseline - 2 year if remaining asymptomatic or at moment of becoming symptomaticThe supraspinatus muscle thickness will be measured on two locations: 1) midpoint of the line cranial to the spina scapula; 2) 2 cm medial to the midpoint of the line cranial to the spina scapulae. One longitudinal and one transverse measurement at each of the scanning sites will be performed. This will be measured in mm.
Humeral glenoid distance (HGD)Baseline - 2 year if remaining asymptomatic or at moment of becoming symptomaticThe HGD is the distance between the most posterior point of the humeral head and the posterior glenoid. This will be measured in mm.
International Physical Activity Questionnaire (IPAQ)Baseline - 2 year if remaining asymptomatic or at moment of becoming symptomaticThe IPAQ will be used to evaluate the physical activity level of the participants. This questionnaire contains 31 questions in 5 domains: 1) physical activity during work; 2) physical activity concerning transport; 3) physical activity by doing household chores; 4) physical activity concerning sport activities; 5) sitting time.
Clinical tests - mobilityBaseline - 2 year if remaining asymptomatic or at moment of becoming symptomaticPassive and active scaption - passive external rotation in supine position with arm in 90° abduction - passive internal rotation in supine position with arm in 90° abduction.
