Complex Regional Pain Syndromes Clinical Trial
Official title:
Prognostic Factors for Complex Regional Pain Syndrome: a Longitudinal Study
The investigators would like to examine the role of some relevant biopsychosocial factors in the development of persistent CRPS. According to the International Classification of Functioning, Disability and Health (ICF) [43], the outcomes will belong to one of the three following components: - Body structures and functions (pain, CRPS severity score (CSS)), - Activities (disability) - Participation (return to work, quality of life). The primary aim is to assess predicting factors for chronification. The secondary aims are: - to evaluate if it is possible to classify acute complex regional pain syndrome (CRPS) patients into subgroups according to their risk of chronification. - to document the course of the disease. The main evaluation criteria will be to determine the impact of the different clinical and non-clinical variables on the course of the CRPS and on the aforementioned outcomes then, which will use as endpoints. - Primary endpoint: disability - Secondary endpoints: participation-QoL, return to work, pain, CRPS severity score.

Type | Measure | Description | Time frame | Safety issue |
---|---|---|---|---|
Primary | Disability | Defined by International Classification of Functioning, Disability and Health (ICF), assessed by Quick DASH (0 to 100 scale) or Lower Extremity Functional Scale (LEFS) (0 to 80 scale) ; higher score means higher disability | 12 months | |
Secondary | Participation - QoL | Defined by International Classification of Functioning, Disability and Health (ICF), assessed by EuroQol5D5L ; higher score in each domain means lower QoL ; lower score in visual analogic scale means lower QoL | 12 months | |
Secondary | Return to work | Rate of patients returning to work at 1 year (full time and / or medical part-time) | 12 months | |
Secondary | Body function - Pain intensity | Defined by International Classification of Functioning, Disability and Health (ICF), assessed by SF-BPI ; pain intensity (severity, means of 4 first items) and the impact of pain on functioning (interference, mean of the seven interference items on a 0-10 scale) ; higher scores mean higher pain (severity or interference) | 12 months | |
Secondary | Body function - CRPS severity score | Defined by Harden et al., signs + symptoms, 0 to 16 scale ; higher score means higher severity | 12 months |
