Effects of Controlled Breathing on Cardiorespiratory Variables in Multiple Myeloma

Summary

A randomized, parallel, double-blind, controlled, clinical trial. Two groups of participants will be included, both receiving a therapeutic exercise intervention and an educational session on the importance of proper breathing over a 6-week period. One of the groups will additionally perform a home-based controlled breathing exercise protocol. Pre- and post-intervention assessments (6 weeks) will be conducted, along with a follow-up evaluation 4 weeks after completion of the intervention. The goal is to determine the effectiveness of adding a controlled breathing exercise program to a therapeutic exercise intervention on cardiorespiratory variables in individuals with multiple myeloma.

Conditions

• Multiple Myeloma (MM)
• Breathing Techniques
• Breathing Exercises
• Exercise Activity
• Diaphragmatic Breathing
• Heart Rate Variability (HRV)

Interventions

OTHER

Controlled breathing exercise protocol + therapeutic exercise + initial education session

In addition to the therapeutic exercise protocol and the educational session on proper breathing, participants will perform a controlled breathing protocol at home twice daily, at least five days per week, throughout the 6-week study period, following the recommendations of the principal investigator. The goal is to integrate slow, gentle, diaphragmatic, nasal breathing into daily life. Additionally, within this same group, two in-person controlled breathing training sessions, each lasting 5 minutes, will be conducted at the hospital to promote correct execution of the technique, one at the beginning of the intervention and another at its completion. To promote adherence and ensure correct and consistent execution, participants will have access through the Web-App to two audio files containing guided breathing instructions and visualization exercises. These recordings were specifically developed for this project by a physiotherapist with more than 20 years of experience.

OTHER

Therapeutic exercise + initial education session

In addition to the educational session on proper breathing, participants will perform: * Three weekly sessions of mobility and muscle-strengthening exercises (two on-site and one home-based) for 6 weeks. The on-site sessions will last between 30 and 40 minutes and will take place at the Rehabilitation Department of Hospital 12 de Octubre in Madrid (a total of 12 on-site sessions-two per week). The home-based exercise program will consist of completing, once per week during the 6-week intervention, a structured session that replicates the logic and technique of the on-site program. A maximum of four absences from the on-site therapeutic exercise program will be allowed, and on those occasions the patient must register via the web application that they completed the prescribed home-based program. * Walk a minimum of 7,000 steps/day or 50 minutes/day, three days per week.
