About

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.

Full description

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.

---

34 participants in 2 patient groups

Telerehabilitation Group (TRG)

Experimental group

Description:

Participants in the Telerehabilitation Group (TRG) will take part in a 12-week multicomponent exercise program delivered online through Microsoft Teams. Sessions will be held twice per week, lasting 45 minutes each, and will include aerobic, strength, flexibility, and balance exercises. Intensity will be individually adjusted according to perceived exertion and functional status. A physiotherapist will conduct the sessions in real time, providing continuous supervision, feedback, and safety monitoring.

Treatment:

Behavioral: Multicomponent Exercise via Telerehabilitation

Home-Based Physiotherapy Group (HBG)

Active Comparator group

Description:

Participants in the Home-Based Physiotherapy Group (HBG) received a 12-week in-home physiotherapy program conducted by a physiotherapist who visited the participants' homes twice per week. Each session lasted approximately 45 minutes and included aerobic, strength, flexibility, and balance exercises, following the same structure as the telerehabilitation protocol. The exercises were individualized according to the participant's clinical condition and physical capacity. Progress and safety were monitored directly during each home session.

Treatment:

Behavioral: Home-Based Physiotherapy
