Influence of Trauma on Pain Area and Widespreadness in Chronic Pain Patients
- Conditions

- Registration Number
- NCT05190367
- Lead Sponsor
- Hannover Medical School
- Brief Summary
It is well known that patients suffering from chronic pain report higher levels of pain, anxiety, and depression if they have experienced a traumatic event. However, little is know about pain area and widespreadness.
In this retrospective study, we want to investigate whether pain area and widespreadness differs in chronic pain patients with and without traumatic events. To test this hypothesis we will retrospectively analyse pain drawings collected at the pain outpatient department from Hannover Medical School. Participants will be divided into four groups depending on the severity of their traumatic events: no trauma; accidental trauma; interpersonal trauma; post-traumatic stress disorder (PTSD).

- Primary Outcome Measures
Name Time Method Difference in pain widespreadness First visit of each patient at the Pain outpatient department of Hannover Medical School between 2019-02-28 and 2020-07-07 Widespread pain index (WPI) derived from electronic pain drawings (SymptomMapper). The score ranges from 0 (no pain) to 19 (pain affects all possible regions).
Difference in pain area First visit of each patient at the Pain outpatient department of Hannover Medical School between 2019-02-28 and 2020-07-07 Pain area derived from electronic pain drawings (SymptomMapper). The score ranges from 0 to 100% body area.
- Secondary Outcome Measures
Name Time Method Difference in mean pain in the last four weeks First visit of each patient at the Pain outpatient department of Hannover Medical School between 2019-02-28 and 2020-07-07 Visual analogue scale from 0 ("no pain") to 100 ("maximal imaginable pain").
Difference in current pain First visit of each patient at the Pain outpatient department of Hannover Medical School between 2019-02-28 and 2020-07-07 Visual analogue scale from 0 ("no pain") to 100 ("maximal imaginable pain").
Difference in stress First visit of each patient at the Pain outpatient department of Hannover Medical School between 2019-02-28 and 2020-07-07 Stress assessed via the 10-item stress scale (PHQ-Stress) from the German version of the Patient Health Questionnaire (PHQ-D). The score ranges from 0 (no stress) to 20 (maximal stress).
Difference in maximal pain in the last four weeks First visit of each patient at the Pain outpatient department of Hannover Medical School between 2019-02-28 and 2020-07-07 Visual analogue scale from 0 ("no pain") to 100 ("maximal imaginable pain").
Difference in acceptable pain First visit of each patient at the Pain outpatient department of Hannover Medical School between 2019-02-28 and 2020-07-07 Visual analogue scale from 0 ("no pain") to 100 ("maximal imaginable pain").
Difference in somatic symptoms First visit of each patient at the Pain outpatient department of Hannover Medical School between 2019-02-28 and 2020-07-07 Somatic symptoms assessed via the 15-item somatic scale (PHQ-15) from the German version of the Patient Health Questionnaire (PHQ-D). The score ranges from 0 (no somatic symptom burden) to 30 (maximal somatic symptom burden).
Difference in anxiety First visit of each patient at the Pain outpatient department of Hannover Medical School between 2019-02-28 and 2020-07-07 Anxiety assessed via the 7-item anxiety scale (GAD-7) from the German version of the Patient Health Questionnaire (PHQ-D). The score ranges from 0 (no anxiety) to 21 (maximal anxiety).
Difference in sleep impairment First visit of each patient at the Pain outpatient department of Hannover Medical School between 2019-02-28 and 2020-07-07 Visual analogue scale from 0 ("no impairment") to 100 ("maximal imaginable impairment").
Difference in pain-related disability First visit of each patient at the Pain outpatient department of Hannover Medical School between 2019-02-28 and 2020-07-07 Pain-related disability assessed via the Pain Disability Index (PDI). The score ranges from 0 (no pain-related disability) to 70 (maximal disability).
Difference in depression First visit of each patient at the Pain outpatient department of Hannover Medical School between 2019-02-28 and 2020-07-07 Depression assessed via the 9-item depression scale (PHQ-9) from the German version of the Patient Health Questionnaire (PHQ-D).
