NCT05481710

Brief Summary

The aim of this study was to investigate predictors of nociplastic shoulder pain. Factors of psychological distress, functionality, fitness, quality of life, quality of sleep, functioning of the parasympathetic system, and lifestyle will be examined. Patients with nociplastic pain will be identified using the classification system proposed by the IASP.

Outcome Measures

Primary Outcomes (3)

  • Pressure Pain Threshold (PPT)

    PPT will be used to assess the pain sensitivity

    Only one time (baseline)

  • Conditioned Pain Modulation (CPM)

    CPM will be used to examine the descending inhibition of nociceptive signals

    Only one time (baseline)

  • Nociplastic Pain Criteria

    The grading system for recognition of nociplastic pain will be used (Kosek et al. 2021).

    Only one time (baseline)

Secondary Outcomes (17)

  • Numeric Pain Rating Scale

    Only one time (baseline)

  • Pain Distribution

    Only one time (baseline)

  • Heart Rate Variability (HRV)

    Only one time (baseline)

  • Range of motion

    Only one time (baseline)

  • Central Sensitization Inventory (CSI)

    Only one time (baseline)

  • +12 more secondary outcomes

Interventions

All participants will be assessed with the specific nociplastic pain criteria

Sampling MethodNon-Probability Sample
Study Population

The current study will include patients with chronic shoulder pain who visit the Hand Surgery-Upper Limb and Microsurgery Department of the General Hospital KAT and healthy participants who study or work at the University of Thessaly.

You may qualify if:

  • patients (men and women) with chronic shoulder pain (lasting more than 3 months, 3/10 Numeric Pain Rating Scale),
  • aged 18-65 years
  • mentally able to follow instructions or
  • healthy volunteers
  • aged 18-65
  • who do not experience pain and have not received analgesic medication in the last trimester.

You may not qualify if:

  • referred shoulder pain from different primary sources of pain (eg shoulder pain in women with mastectomy or stroke),
  • pain manifested by movements in the neck,
  • shoulder arthroplasty or fractures or dislocation of the shoulder, -
  • diagnosis of chronic pain syndrome such as fibromyalgia, chronic fatigue syndrome, chronic regional pain syndrome, cancer diagnosis, osteoporosis, rheumatic inflammatory diseases,
  • use of medication for neurological/psychiatric disorders,
  • the presence of gastrointestinal or renal disease
  • taking medication that may affect the assessment results, such as calcium channel blockers that could alter HRV,
  • pregnancy or childbirth before 1 year will be excluded from the study.
