Profiling the RCRSP Patient: a Pain Phenotype Classification Algorithm

University of Thessaly100 enrolled

Overview

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

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.
