From November 2022, patients treated \u2a7e1\u2009year previously were recalled for clinical evaluation. A dedicated instrument (DASH questionnaire, Disabilities of the Arm, Shoulder and Hand) was employed to assess residual disability. Multivariate logistic regression analysis was used to investigate predictors of disability.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>Forty-nine patients aged 61.1\u2009\u00b1\u200911.5\u2009years and 73.5% female with CRPS-1 of the upper limb were included.

The disease had fully resolved in 46 patients (93.9%) for whom the diagnostic criteria were no longer recognized. According to the DASH score, 38 patients (77.6%) resulted free of functional limitations, whereas 11 patients (22.4%) were still suffering from disability. The DASH score was positively correlated with residual visual analogue scale (VAS; Spearman\u2019s Rho\u2009=\u20090.61; P\u2009&lt;\u2009.001). Predictors of residual disability were younger age (odds ratio [OR]: 0.77, 95% CI: 0.63-0.93; P\u2009=\u2009.012) and delay between disease onset and treatment (OR: 1.45, 95% CI: 1.13-1.96; P\u2009=\u2009.004).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions:<\/jats:title>\n                    <jats:p>In this real-life study, neridronate parenteral treatment provided a full recovery of CRPS-1 in over 3 quarters of patients, provided they are treated early.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/11795441241294098","type":"journal-article","created":{"date-parts":[[2024,11,6]],"date-time":"2024-11-06T04:24:16Z","timestamp":1730867056000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":4,"title":["Is CRPS-1 a Chronic Disabling Disease?
