Objective: To assess the prevalence of pain in adults with spasticity and to assess the association between the subjective experience of pain and spasticity. Design: Cross-sectional study. Setting: outpatient spasticity management clinic of a rehabilitation centre. Patients: Patients with upper motor neuron lesions and spasticity (n = 131) were recruited. Methods: We assessed pain intensity and location, relationship between spasticity and pain perception, and perception of pain relief from botulinum toxin type-A (BoNTA) injections. Main outcome measures: Pain perception rated on a 10-point numerical rating scale and pain quality. Results: 65% of the patients with spasticity reported presence of pain and 60% described it as an aching pain. More patients reported pain with movement (34%) compared to rest (21%). There was a statistically poor correlation between the severity of pain and spasticity (r = 0.16; p > 0.05). Most patients (80%) believed that their pain was related to spasticity and 62% reported that BoNTA injections decreased their pain. Conclusions: The high incidence of pain noted within our sample suggests that physicians may have to consider pain management as part of spasticity treatment. Participants reported that their pain was related to their spasticity, and that it decreased after BoNTA treatment. Further study is needed to explore the relationships between objective measures of spasticity and pain.RĂSUMĂ: Relation entre la toxine botulique, la spasticitĂ© et la douleur : une enquĂȘte sur la perception des patients. Objectif: Le but de l'Ă©tude Ă©tait de dĂ©terminer la prĂ©valence de la douleur chez des adultes souffrant de spasticitĂ© et d'Ă©tudier l'association entre l'expĂ©rience subjective de la douleur et la spasticitĂ©. Devis de l'Ă©tude: Il s'agit d'une Ă©tude transversale. Contexte: Cette Ă©tude a Ă©tĂ© rĂ©alisĂ©e auprĂšs de patients frĂ©quentant une clinique dĂ©diĂ©e au traitement de la spasticitĂ© dans un centre de rĂ©adaptation. Patients: Des patients atteints de lĂ©sions du neurone moteur supĂ©rieur et de spasticitĂ© ont Ă©tĂ© recrutĂ©s (n = 131). MĂ©thode: Nous avons Ă©valuĂ© l'intensitĂ© et la localisation de la douleur, la relation entre la spasticitĂ© et la perception de la douleur ainsi que la perception du soulagement de la douleur suite Ă des injections de toxine botulique de type A (BoNTA). Principaux critĂšres d'Ă©valuation: Les critĂšres utilisĂ©s Ă©taient la perception de la douleur Ă©valuĂ©e sur une Ă©chelle numĂ©rique de 10 points et la qualitĂ© de la douleur. RĂ©sultats: Soixante-cinq pour cent des patients prĂ©sentant de la spasticitĂ© ont rapportĂ© la prĂ©sence de douleur et 60% l'ont dĂ©crite comme une douleur sourde. Plus de patients ont rapportĂ© de la douleur au mouvement (34%) qu'au repos (21%). La corrĂ©lation entre la sĂ©vĂ©ritĂ© de la douleur et la spasticitĂ© Ă©tait faible au point de vue statistique (r = 0,16 ; p > 0,05). La plupart des patients (80%) croyaient que leur douleur Ă©tait reliĂ©e Ă la spasticitĂ© et 62% rapportaient que les injections de BoNTA diminuaient la douleur. Conclusions: L'incidence ...
