Study summary

The aim of this study is to collect a sum of different characteristics that have been mentioned previously in people presenting with RCRSP and by clustering them to create a phenotype system which may assist the individualisation of their management

Read the detailed description

This study will be conducted at a hospital environment by recruiting people that will seek help for their shoulder pain by a specialist upper- limb Orthopaedic Surgeon at the Department of Hand \& Upper Limb Microsurgery of the 'KAT General Hospital' in Athens, Greece. Participants that will be diagnosed with RCRSP by the orthopaedic surgeon and fulfil the eligibility criteria will undergo a series of one-off measurements. Written consent will have to be obtained before a sum of self-reported outcome measures and objective testing will take place. The main categories for which outcome measures will be used are: pain, function, psychosocial and lifestyle factors.

What researchers measure

Primary outcomes

  1. Numeric Pain Rating Scale (NPRS)

    Obtain a measurement of pain Score: 0-10 Higher scores indicate more pain

    Time frame: Once - Baseline

  2. Western Ontario Rotator Cuff Index (WORC)

    Assess the self-reported functional ability of participants Score: 0-100 % Higher scores indicate higher functional status

    Time frame: Once - Baseline

  3. The Self-Report Leeds Assessment of Neuropathic Symptoms & Signs (SLANSS)

    Identify possible participants with neuropathic type of pain Score: 0-24 Score \>12 indicates neuropathic pain

    Time frame: Once - Baseline

  4. Central Sensitisation Inventory (CSI)

    Identify participants suspicious of central sensitisation symptoms Score: 0-100 Score\>40 indicates central sensitisation

    Time frame: Once - Baseline

  5. Pain Drawings (PD)

    Capture painful body locations for participants with the spectrum of pathologies

    Time frame: Once - Baseline

  6. Nociplastic Pain Flow Chart by IASP

    Identification of Predominant Pain Mechanism, especially participants with possible nociplastic pain

    Time frame: Once - Baseline

  7. Quantitative Sensory Testing (QST)

    Assessment of Pressure Pain Threshold, Conditioned Pain Modulation \& Temporal Summation

    Time frame: Once - Baseline

  8. Range of Motion (ROM)

    Assess Range of motion of the movements of interest

    Time frame: Once - Baseline

  9. Dynamometry

    Assess strength and explore pain provocation in participants

    Time frame: Once - Baseline

  10. Posterior Shoulder Endurance Test (PSET)

    Assess the endurance of the Rotator Cuff myotendinous unit

    Time frame: Once - Baseline

  11. Hospital Anxiety & Depression Scale (HADS)

    Obtain a score of Anxiety \& Depression among participants Score: 0-42 (Two scales between 0 \& 21 each - one for anxiety and 1 for depression) Higher Scores indicate higher anxiety \& depression

    Time frame: Once - Baseline

  12. Pain Catastrophising Scale (PCS)

    Explore how the pain experience is perceived by the individual Scale: 0-52 Higher scores indicate higher levels of catastrophising

    Time frame: Once - Baseline

  13. Tampa Scale of Kinesiophobia (TSK)

    Explore fear of movement and avoidance of participants Score: 17-68 Higher scores indicate higher levels of Kinesiophobia, cut-off point: scores \>37 are indicative of kinesiophobia

    Time frame: Once - Baseline

  14. Pain Self-Efficacy Questionnaire (PSEQ)

    Assess the ability of the participant to cope with a spectrum of activities Score: 0-60 Lower scores indicate less self-efficacy

    Time frame: Once - Baseline

  15. Allostatic Index-5 (ALI-5)

    Investigate psychosocial stressors reflective of chronc adaptive states for 'wear \& tear' of the human body Score: 0-5 Higher score indicating higher allostatic load

    Time frame: Once - Baseline

  16. EuroQol-5Dimension (EQ-5D)

    Investigate quality of life levels of participants Score: 5-likert with no problem, slight, moderate, severe and extreme in each of the dimensions plus the 0-100 VAS as a global rating of self-perceived health with higher scores indcating better health

    Time frame: Once - Baseline

  17. Pittsburgh Sleep Quality Index (PSQI)
