Aims: Previous research has shown the possibility to use the pre-operative period to improve a patient's tolerance for surgery. However, there is limited experience with prehabilitation in cardiac surgery. The aim of this study is to evaluate the effect of a comprehensive personalized teleprehabilitation programme on major adverse cardiac events (MACE) in patients scheduled for elective cardiac surgery. Secondary outcomes are post-operative complications, cardiovascular risk factors, quality of life, and cost-effectiveness., Methods and Results: In this single-centre randomized controlled trial, patients are eligible for inclusion when they are ≥18 years of age and cardiac surgery is scheduled at least 8 weeks from informed consent. Participants will be randomized to the teleprehabilitation group or the control group. After a digital baseline screening for perioperative risk factors, patients in the intervention arm can pre-operatively be referred to one or more of the prehabilitation modules (functional exercise training, inspiratory muscle training, psychological support, nutritional support, and/or smoking cessation). The programme is targeted at a duration of at least 6 weeks. It is executed by a multidisciplinary team using (video)calls and supported by a custom-made digital platform. During the pre-operative period, the platform is also used to inform patients about their upcoming surgery and for telemonitoring., Conclusion: Reducing perioperative risk factors might result in a reduction of MACE, post-operative complications, length of stay, and cardiovascular risk factors, as well as improved quality of life. Cost-effectiveness will be evaluated., (© The Author(s) 2021. Published by Oxford University Press on behalf of the European Society of Cardiology.)

Objective: To test the efficacy of low-level laser therapy on lateral ankle sprains as an addition to a standardized treatment regimen, a trial was conducted in which high-dose laser (5J/cm2), low-dose laser (0.5J/cm2), and placebo laser therapy (0J/cm2) at skin level were compared., Design: Randomized, double-blind, controlled clinical trial with a follow-up of 1 year. Patients, therapists, assessors, and analysts were blinded to the assigned treatment., Setting: An ambulatory care setting., Patients: After informed consent and verification of exclusion criteria, 217 patients with acute lateral ankle sprains were randomized to three groups from September 1, 1993, through December 31, 1995., Interventions: Twelve treatments of 904nm laser therapy in 4 weeks as an adjunct to a standardized treatment regimen of 4 weeks of brace therapy combined with standardized home exercises and advice. The laser therapy device used was a 904nm Ga-As laser, with 25-watt peak power and 5,000 or 500Hz frequency, a pulse duration of 200nsec, and an irradiated area of 1cm2., Primary Outcome Measures: Pain and function as reported by the patient., Results: Intention-to-treat analysis of the short-term results showed no statistically significant difference on the primary outcome measure, pain (p = .41), although the placebo group showed slightly less pain. Function was significantly better in the placebo group at 10 days (p = .01) and 14 days (p = .03) after randomization. The placebo group also performed significantly better on days of sick leave (p = .02) and at some points for hindrance in activities in daily life and pressure pain, as well as subjective recovery (p = .05). Intention-to-treat analysis showed that total days of absenteeism from work and sports were remarkably lower in the placebo group than in the laser groups, ranging from 3.7 to 5.3 and 6 to 8 days, respectively. The total number of relapses at 1 year in the low-dose laser group (n = 22) was significantly higher (p = .04) than in the other two groups (high laser, n = 13; placebo, n = 13). Subgroup analysis to correct for possible confounders did not alter these findings., Conclusions: Neither high- nor low-dose laser therapy is effective in the treatment of lateral ankle sprains.
