The goal of this clinical trial is to learn if a multicomponent exercise program delivered through telerehabilitation improves physical fitness and quality of life in older adults with multiple chronic conditions living in Antioquia, Colombia. The main questions it aims to answer are: Does telerehabilitation with multicomponent exercise improve physical performance compared to home-based physiotherapy provided in person by a physiotherapist? Does this program enhance participants' quality of life and functional independence? Participants will: Join a 12-week exercise program with two 45-minute online sessions per week, led by a physiotherapist through Microsoft Teams. Perform exercises including aerobic, strength, flexibility, and balance training, adapted to their health condition. Complete pre- and post-intervention assessments of physical function (Senior Fitness Test, SPPB) and quality of life (WHOQOL-BREF). Researchers will compare the telerehabilitation group to a home-based physiotherapy group, in which physiotherapists visit participants at their homes, to determine whether the online multicomponent exercise intervention is effective, safe, and feasible for older adults with multiple chronic conditions.
This study is a randomized, single-blind, parallel-group controlled clinical trial designed to evaluate the implementation and effects of a multicomponent exercise program delivered through synchronous telerehabilitation in older adults with multiple chronic conditions living in Antioquia, Colombia. Population aging has led to a growing prevalence of multimorbidity, characterized by the coexistence of cardiovascular, respiratory, metabolic, and musculoskeletal conditions. This clinical complexity is commonly associated with declines in physical function, increased frailty, loss of independence, and reduced quality of life. Although exercise-based rehabilitation is a key component of chronic disease management, access to supervised programs remains limited for many older adults due to geographic barriers, mobility restrictions, and resource constraints, particularly in low- and middle-income settings. Telerehabilitation, defined as the remote delivery of rehabilitation services through information and communication technologies, has emerged as an alternative approach to improve access to physiotherapy services while maintaining professional supervision. Multicomponent exercise programs that integrate aerobic, resistance, flexibility, and balance training have demonstrated benefits for physical and functional health in older populations. However, there is limited evidence regarding the use of supervised telerehabilitation models for older adults with multimorbidity in Colombia. Participants are allocated in a 1:1 ratio to either a Telerehabilitation Group or a Home-Based Physiotherapy Group. Randomization is stratified by sex and primary diagnosis to promote balance between groups. Outcome assessors are blinded to group allocation. The telerehabilitation intervention consists of a structured, supervised multicomponent exercise program delivered in real time using videoconferencing technology. Sessions are conducted twice weekly over a 12-week period and follow a standardized format that includes warm-up activities, aerobic conditioning, resistance exercises using body weight or elastic bands, flexibility training, balance exercises, and cool-down. Exercise intensity and progression are individualized based on functional capacity, health status, and participant tolerance. All sessions are supervised synchronously by a licensed physiotherapist, who provides guidance, monitors responses to exercise, and applies predefined safety procedures. The comparison group receives an equivalent multicomponent exercise program delivered face-to-face in the participant's home by a physiotherapist over the same intervention period. Session structure, exercise components, and progression principles are comparable between groups, with the primary difference being the mode of delivery. Both groups receive standardized educational guidance related to physical activity, healthy aging, and self-management strategies. Assessments are conducted at baseline and immediately after completion of the intervention period. Study procedures include monitoring adherence, documenting attendance, and recording any adverse events occurring during supervised exercise sessions. These elements are used to evaluate feasibility, acceptability, and safety of the intervention in both delivery modalities. Ethical approval was obtained from the Research Ethics Committee of Fundación Universitaria María Cano. All participants provided written informed consent prior to enrollment. Participant confidentiality and data protection are ensured in accordance with institutional protocols and national regulations, including secure management of digital platforms used for telerehabilitation. This trial aims to generate context-specific evidence on the use of supervised telerehabilitation as a strategy to deliver physiotherapy services to older adults with multiple chronic conditions, supporting future integration of digital rehabilitation models into clinical practice and public health initiatives in Colombia.

A supervised multicomponent exercise program delivered remotely through Microsoft Teams. The program includes aerobic, strength, flexibility, and balance exercises performed twice per week for 12 weeks, under real-time supervision by a physiotherapist. The exercises are individualized according to each participant's health status and physical capacity.
A physiotherapist-led multicomponent exercise program conducted in person at the participant's home. The intervention includes aerobic, strength, flexibility, and balance exercises, delivered twice per week for 12 weeks. The physiotherapist provides individualized progression, monitors adherence, and ensures participant safety during each home session.

Change in Physical Performance Measured by the Short Physical Performance Battery (SPPB)
The Short Physical Performance Battery (SPPB) is a standardized test that assesses lower extremity function through three components: balance, gait speed, and chair stand performance. Each component is scored from 0 to 4, with a total score ranging from 0 to 12, where higher scores indicate better physical performance. The SPPB has been validated as a predictor of functional capacity, frailty, and disability in older adults. In this study, the SPPB will be used to evaluate changes in physical performance before and after the 12-week intervention in both groups.

Change in Physical Fitness Measured by the Senior Fitness Test (SFT)
The Senior Fitness Test (SFT) is a standardized battery designed to assess physical fitness in older adults across multiple components of functional capacity. It includes six subtests evaluating lower-body strength, upper-body strength, aerobic endurance, flexibility, agility, and dynamic balance: chair stand, arm curl, 2-minute step, chair sit-and-reach, back scratch, and 8-foot up-and-go. Each subtest is scored independently using performance-based measures. There is no single composite score for the SFT. The minimum and maximum values for each subtest are as follows: Chair Stand Test: number of repetitions completed in 30 seconds (minimum = 0 repetitions; no fixed maximum). Arm Curl Test: number of repetitions completed in 30 seconds (minimum = 0 repetitions; no fixed maximum). 2-Minute Step Test: number of steps completed in 2 minutes (minimum = 0 steps; no fixed maximum). Chair Sit-and-Reach Test: distance reached in centimeters relative to the toes (negative values indicate

Change in Quality of Life Measured by the WHOQOL-BREF Questionnaire
The World Health Organization Quality of Life Instrument (WHOQOL-BREF) is a validated questionnaire that assesses quality of life across four domains: physical health, psychological health, social relationships, and environment. The instrument consists of 26 items rated on a 5-point Likert scale. Domain scores are calculated and transformed to a 0-100 scale following World Health Organization guidelines. For all domains and the overall quality of life score, higher scores indicate better perceived quality of life, while lower scores indicate poorer perceived quality of life. In this study, the WHOQOL-BREF will be administered at baseline and after the 12-week intervention to evaluate changes in overall and domain-specific quality of life in both study groups.
