Nociplastic Pain in Patients With Chronic Shoulder Pain

Recruiting
Conditions
Chronic Shoulder Pain
Registration Number
NCT05481710
Lead Sponsor
University of Thessaly
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.

Detailed Description

The main part of the study will include patients with chronic shoulder pain who visit the Hand Surgery-Upper Limb and Microsurgery Department of the General Hospital KAT. The measurements will be performed in one session. Once participants have been informed of the purpose and procedure of the study and given written consent, they will complete their demographics and a series of questionnaires and questions about their pain history. They will then be examined by a doctor and finally subjected to dynamometry, a functional test and two quantitative sensory tests.

Study & Design

Study Type
OBSERVATIONAL
Study Design
Not specified
Primary Outcome Measures
NameTimeMethod
Pressure Pain Threshold (PPT)Only one time (baseline)

PPT will be used to assess the pain sensitivity

Nociplastic Pain CriteriaOnly one time (baseline)

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

Conditioned Pain Modulation (CPM)Only one time (baseline)

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

Secondary Outcome Measures
NameTimeMethod
Central Sensitization Inventory (CSI)Only one time (baseline)

CSI wiil be used to assess the CS symptoms

Numeric Pain Rating ScaleOnly one time (baseline)

Pain intensity will be assessed with Numeric Pain Rating Scale. Participants will score from 0 (no pain) to 10 (the worst pain they have ever experienced).

Pain DistributionOnly one time (baseline)

Pain location will be recorded using the Pain Distribution App (PDA) which is a self-reported tool to assess the distribution and spread of body pain areas. The PDA has demonstrated reliability.

Heart Rate Variability (HRV)Only one time (baseline)

HRV testing will be used to assess the function of autonomic nervous system

Range of motionOnly one time (baseline)

Active and passive range of motion will be measured using a goniometer. It will be assessed the flexion, abduction, and external rotation. Participants will be a standing position for flexion and abduction assessment and in prone position for external rotation.

Hospital Anxiety and Depression Scale (HADS)Only one time (baseline)

Anxiety and depression will be measured with Hospital Anxiety and Depression Scale (HADS). HADS includes 14 items, 7 for Anxiety and 7 for Depression. The overall score range 0-42 and 0-21 for the different categories. A cut-off 8/21 has been recommended.

Brief Illness Perception Questionnaire (BIPQ)Only one time (baseline)

BIPQ will be used to estimate the perception of pain severity

Pain Sensitivity Questionnaire (PSQ)Only one time (baseline)

PSQ is a self-reported tool and it will be used to assess pain sensitivity

Pittsburgh Sleep Quality Index (PSQI)Only one time (baseline)

The Pittsburgh Sleep Quality Index (PSQI) is an effective instrument used to measure the quality and patterns of sleep in adults.

Tampa Scale Kinesiophobia (TSK)Only one time (baseline)

TSK is a self-reported scale and it will be used to assess the kinesiophobia

EuroQol-5 Dimension (EQ-5D)Only one time (baseline)

EQ-5D will be used to assess the quality of life

3-Minute Step Test (3MST)Only one time (baseline)

3MST will be used to assess the cardiovascular capacity

Hand GripOnly one time (baseline)

Hand Grip will be used to assess the strength of forearm muscles

Pain Catastrophizing Scale (PCS)Only one time (baseline)

PCS is a self-reported scale which estimates the catastrophization

Work Ability Index (WAI)Only one time (baseline)

WAI will be used to assess the work ability

Pain Self-Efficacy Questionnaire (PSEQ)Only one time (baseline)

PSEQ will be used to estimate the self-efficacy

Shoulder Pain and Disability Index (SPADI)Only one time (baseline)

SPADI is a self-reported questionnaire and it will be used to assess the disability
