Intra-articular botulinum toxin A injection for painful base-of-thumb osteoarthritis: a double-blind, randomised, controlled, phase 3 trial (RHIBOT).

Background: Intra-articular botulinum toxin A injection might have analgesic effects in patients with joint diseases. We aimed to compare the effects of intra-articular botulinum toxin A injection with those of intra-articular saline injection for patients with painful base-of-thumb osteoarthritis.

Methods: RHIBOT was a double-blind, randomised, controlled, phase 3 trial conducted at Cochin Hospital, Paris, France.

Patient acceptable symptom state for patient-reported outcomes in people with non-specific chronic low back pain.

Background: The patient acceptable symptom state (PASS) is a treatment-response criterion developed to determine the clinical relevance of a treatment effect. Its estimates for some patient-reported outcomes (PROs) in non-specific chronic low back pain (cLBP) are lacking and the stability of PRO estimates between independent cLBP populations is unknown. We hypothesized that these PRO estimates will be stable.

Development of a new patient-reported outcome measure assessing activities and participation in people with lumbar spinal stenosis: The Cochin Spinal Stenosis 19-item questionnaire.

Background: Lumbar spinal stenosis (LSS) is the leading cause of spinal surgery in people over 65-years old. In people with LSS, generic self-administered questionnaires are the most commonly used PROs to assess health-related quality of life, global activity limitation, and low back pain-located activity limitation.

Aim: The aim was to develop a new patient-reported outcome measure assessing activities and participation in people with LSS.

Evaluation of the impact of a nurse-led program of patient self-assessment and self-management in axial spondyloarthritis: results of a prospective, multicentre, randomized, controlled trial (COMEDSPA).

Objective: To evaluate the impact of a nurse-led program of self-management and self-assessment of disease activity in axial spondyloarthritis.

Methods: Prospective, randomized, controlled, open, 12-month trial (NCT02374749). Participants were consecutive axial spondyloarthritis patients (according to the rheumatologist) and nurses having participated in a 1-day training meeting.
