factors associated with pain, disability and quality of life in patients suffering from frozen shoulder

background: frozen shoulder is resulting in limb disability and reduction of quality of life but the factors associated with patients’ disability and quality of life is not clear. to assess pain, disability, the quality of life and factors associated with them in patients suffering from frozen shoulder.  methods: we enrolled 120 patients (37 men and 83 women) with phase-ii idiopathic frozen shoulder in our cross-sectional study. demographic data were collected and shoulder range of motion was measured in four different directions (elevation, abduction, external and internal rotation) in both upper limbs. patients were asked to fill out visual analog scale for pain (vas) and, short-form health survey questionnaire (sf-36) as well as disabilities of the arm, shoulder and hand (dash) questionnaires. we asked the patients to fill out the hamilton anxiety and depression questionnaires. results: the mean of vas pain, dash, pcs, and mcs scores were 69(18), 53(17), 35(8.0), and 42(10) respectively. all the domains of sf36 questionnaires where below the normal population except physical function. vas pain score was correlated to hamilton depression scores in both bivariate and mulivarilable analysis. dash score were correlated to sex, age, rom, and both hamilton anxiety and depression scores; however, dash score only impact with hamilton anxiety and rom independently. pcs is correlated to age and mcs to hamilton depression. conclusion: patient with frozen shoulder are more suffering from pain and disability secondary to psychiatric parameters such as depression and anxiety than demographic features or even restriction of range of motion.
