Effects of a videoconference-based therapeutic exercise intervention on the musculoskeletal pain of eldercare workers: protocol for the ReViEEW randomized controlled trial.

BACKGROUND: Prevalence of musculoskeletal pain is high among eldercare workers, and therapeutic exercise has shown to be effective for its management. Although telerehabilitation is an increasingly used alternative for delivering therapeutic exercise, no studies have assessed synchronous group telerehabilitation interventions for the management of musculoskeletal disorders. Thus, the aim of this article is to describe the protocol of a randomized controlled trial that will assess the effects of a videoconference-based group therapeutic exercise intervention on the musculoskeletal pain of eldercare workers. METHODS: This multicenter trial will randomly assign 130 eldercare workers to either a control or experimental group. Participants in the control group will not receive any intervention, and participants in the experimental group will take part in a 12-week remote supervised videoconference-based intervention, consisting of 2 weekly 45-min group sessions. Each session will include 4 sets of 6 progressive resistance exercises for the lower limbs, upper limbs and trunk, performed with bodyweight and elastic bands at moderate-high intensity. Following the 12 weeks, participants in the experimental group will be provided with material for autonomously carry on the therapeutic exercises and advised to continue performing 2 weekly sessions on their own until a 48-week follow-up. Assessments will be performed at baseline, 12 and 48 weeks. Primary outcome will be average pain intensity in the low back during the last 7 days, measured by the 0-10 Numerical Rating Scale. Secondary outcomes will include additional measures of musculoskeletal pain, psycho-affective state, work-related variables, and physical fitness. DISCUSSION: This will be the first trial, to our knowledge, assessing whether a remote delivery of a group therapeutic exercise intervention via videoconference is effective for reducing the musculoskeletal pain, improving the psycho-affective state and physical fitness, and enhancing the work-related parameters in eldercare workers. If successful, this study will provide innovative tools for implementing effective, scalable and affordable interventions to tackle musculoskeletal disorders in the workplace. It will also highlight the utility of telehealth, and address the importance of therapeutic exercise to manage musculoskeletal pain in a critical population for the future of the aging societies as it is the eldercare workers. TRIAL REGISTRATION: The study protocol was prospectively registered at ClinicalTrials.gov (registration number: NCT05050526) on September 20, 2021.

Effects of Multicomponent Exercise on Frailty in Long-Term Nursing Homes: A Randomized Controlled Trial.

OBJECTIVES: To determine the effect of multicomponent exercise on frailty and related adverse outcomes in residents of long-term nursing homes (LTNHs). DESIGN: A single-blind randomized controlled trial. SETTING: Ten LTNHs in Gipuzkoa, Spain. PARTICIPANTS: The study sample comprised 112 men and women aged 70 years or older who scored 50 or higher on the Barthel Index, 20 or higher on the MEC-35 test (an adapted and validated version of the Mini-Mental State Examination in Spanish), and who were capable of standing up and walking independently for at least 10 m. INTERVENTION: Subjects in the control group (CG) participated in routine activities. The intervention group (IG) participated in a 6-month program of individualized and progressive multicomponent exercise at moderate intensity. MEASUREMENTS: Frailty was assessed by four different scales at baseline and at 6 months. The Barthel Index was measured at baseline and at 12 months. Frailty-related adverse outcomes were recorded from 12 months before to 12 months after starting the intervention. RESULTS: A lower prevalence of frailty was observed in the IG compared with the CG according to Fried's frailty phenotype, Short Physical Performance Battery, and Tilburg Frailty Indicator after 6 months (p < .05). There was a decline in the CG on the Barthel Index after 12 months (p < .05), whereas score was maintained in the IG. Both groups experienced a similar number of falls before and after the intervention (p > .05), but during the 6-month intervention period, fewer falls were observed in the IG than the CG (p < .05). Lower overall mortality was observed 12 months after starting the intervention for the IG than the CG (1 vs 6, respectively; p = .05). CONCLUSION: Individualized and progressive multicomponent exercise at moderate intensity seems to be effective to prevent falls and reduce frailty and mortality.
