RESUMEN
INTRODUCTION: Rehabilitation can improve outcomes after reverse shoulder arthroplasty (RSA). However, low adherence to rehabilitation and compliance rates are some of the main barriers. To address this public health issue, the goal of this research was to pilot test and evaluate the effectiveness of a chatbot to promote adherence to home rehabilitation in patients undergoing RSA. METHODS: A randomized pilot trial including patients undergoing RSA and early postoperative rehabilitation was performed. The control group received standard home rehabilitation; the experimental group received the same intervention supervised with a chatbot, with automated interactions that included messages to inform, motivate, and remember the days and exercises for 12 weeks. Compliance with rehabilitation and clinical measures of shoulder function, pain, and quality of life were assessed. RESULTS: 31 patients (17 experimental) with an average age of 70.4 (3.6) completed the intervention. Compliance was higher in the experimental group (77% vs. 65%; OR95% = 2.4 (0.5 to 11.4)). Statistically significant between-group differences with a CI of 95% were found in the QuickDASH questionnaire and self-reported quality of life. No differences were found in the rest of the measures. CONCLUSIONS: This pilot study suggests that the chatbot tool can be useful in promoting compliance with early postoperative home rehabilitation in patients undergoing RSA. Future randomized trials with adequate power are warranted to determine the clinical impact of the proposal.
RESUMEN
INTRODUCTION: Rotator cuff calcific tendinopathy (RCCT) involves calcific deposits in the rotator cuff. Non-surgical interventions such as extracorporeal shockwave therapy (ESWT) and ultrasound-guided percutaneous irrigation of calcific tendinopathy (US-PICT) are recommended for its early management. Exercise therapy (ET) has shown to be an effective intervention for people with rotator cuff tendinopathy, but it has not been formally tested in RCCT. The main objective of this study is to compare the effectiveness of an ET programme with ESWT and US-PICT in people with RCCT. As a secondary aim, this study aims to describe the natural history of RCCT. METHODS AND ANALYSIS: A randomised, single-blinded four-group clinical trial will be conducted. Adults from 30 to 75 years diagnosed with RCCT who accomplish eligibility criteria will be recruited. Participants (n=116) will be randomised into four groups: ET group will receive a 12-week rehabilitation programme; ESWT group will receive four sessions with 1 week rest between sessions during 1 month; US-PICT group will receive two sessions with 3 months of rest between sessions; and (actual) wait-and-see group will not receive any intervention during the 12-month follow-up. The primary outcome will be shoulder pain assessed with the Shoulder Pain and Disability Index at baseline, 2 weeks, 4 months, 6 months and 12 months from baseline. The primary analysis will be performed at 12 months from baseline. Secondary outcomes will include pain, range of motion, patient satisfaction and imaging-related variables. Moreover, the following psychosocial questionnaires with their corresponding outcome measure will be assessed: Central Sensitization Inventory (symptoms related to central sensitization); Pain Catastrophizing Scale (pain catastrophizing); Tampa Scale for Kinesiophobia 11 items (fear of movement); Fear Avoidance Belief Questionnaire (fear avoidance behaviour); Hospital Anxiety and Depression Scale (anxiety and depression); Pittsburgh Sleep Quality Index (sleep quality); and the EuroQol-5D (quality of life). An intention-to-treat analysis will be performed to reduce the risk of bias using a worst-case and best-case scenario analysis. ETHICS AND DISSEMINATION: Ethics committee approval for this study has been obtained (reference number: 1718862). The results of the main trial will be submitted for publication in a peer-reviewed journal. TRIAL REGISTRATION NUMBER: NCT05478902.

Ankle torque is the most frequent injury mechanism encountered in traumatology. It usually develops as an ankle sprain, and often produces an ankle fracture. Signs and symptoms are very unspecific on the differential diagnosis, and conventional radiographs must be obtained to confirm it. This study compares ultrasound and standard X-ray images values found in ankle sprain-related fracture diagnoses. A 3-month prospective study was carried out on 52 patients with ankle torque. First, an ultrasound diagnosis was made by the first researcher at their arrival to the emergency department, usually consisting of a longitudinal section of the fibula, tibia, and V metatarsal. Then, a blinded independent investigator carried out the usual diagnosis protocol using traditional radiographs. When the required number was obtained, a third independent investigator evaluated the results. A Chi-squared test was used to contrast the outcomes between sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) comparing a non-inferiority hypothesis of our protocol against standard X-ray images screening. Echography showed to be at least as good as standard radiographs on the screening of ankle torque-related fractures (p = 0.02). In our series of patients, nearly 8% of fractures are misdiagnosed with plain radiographies, which concurs with the lower limit found in the bibliography. All the false negatives on radiographs were true positives in the first ultrasound assessment. The average time for the ultrasound protocol was 42 s. An ultrasound is at least as effective as conventional X-ray images when used in diagnosing ankle sprain-related fractures, regardless of age or sex and could in fact be better. The use of echography could reduce the number of radiographies performed when diagnosing these kinds of fractures, thereby reducing the amount of radiation exposure and expediting the diagnostic process as well as the "in situ diagnosis".Level of clinical evidence 2 [prospective cohort (N > 30 patients) study].
