About this study

Official title: Multimodal Respiratory Physiotherapy Including Incentive Spirometry and Positive Expiratory Pressure for Women Treated for Breast Cancer With Radiotherapy: a Pilot Randomised Controlled Trial.

Radiotherapy is an important treatment for breast cancer, but it may affect lung function and physical ability, making everyday activities more difficult. Breathing exercises may help women recover after treatment, although more research is needed.

The main aim of this pilot study was to assess whether a four-week respiratory physiotherapy programme was practical and safe for women treated for breast cancer with radiotherapy. The study also explored its potential benefits for lung function, physical ability, physical activity, fatigue and quality of life.

Participants were randomly assigned to two groups. Both groups received patient education and an individualised exercise programme. In addition, one group performed breathing exercises at home using two devices: one to encourage deep breathing (incentive spirometry) and another to provide resistance when breathing out (positive expiratory pressure). The study compared both groups to explore whether adding these breathing exercises provided additional benefits.

Read the detailed description

This single-centre, two-arm, parallel-group, assessor-blinded pilot randomised controlled trial was conducted at the Hospital Universitario Príncipe de Asturias in Alcalá de Henares, Spain. Physiotherapy interventions were delivered at the University of Alcalá.

Participants were allocated using a computer-generated randomisation sequence, with allocation concealment maintained through sequentially numbered, opaque, sealed envelopes. Outcome assessments were conducted by researchers who remained unaware of group allocation.

The physiotherapy intervention began three months after completion of radiotherapy and lasted four weeks. Participants attended four individual, face-to-face physiotherapy sessions, scheduled once weekly. The programme included patient education and individually prescribed aerobic and resistance exercise, performed independently at home or in community settings. Additional respiratory training was performed using incentive spirometry and positive expiratory pressure devices, following individual instruction and supervision.

Exercise and respiratory training were prescribed according to each participant's physical condition and tolerance. Physical activity was monitored using wrist-worn activity trackers, while adherence to the intervention was reviewed during the weekly sessions.

Assessments were conducted at five time points: before breast cancer surgery, after surgery, three months after radiotherapy (pre-intervention), four months after radiotherapy (post-intervention), and six months after radiotherapy (follow-up).

Feasibility was assessed through recruitment, retention, attendance, and adherence to the prescribed activities. Safety was evaluated by recording adverse events during the intervention period. Clinical outcomes were analysed exploratorily to estimate changes over time and between-group differences, accounting for age, body mass index, and the number of radiotherapy sessions.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Incentive Spirometry (IS) and Positive Expiratory Pressure (PEP) TrainingOther

    Participants completed a four-week home-based respiratory training programme combining incentive spirometry (IS) and positive expiratory pressure (PEP) using Voldyne 5000 and Threshold PEP devices, respectively.

    Training was performed for at least 30 minutes per day, five days per week, comprising 2-4 sets of 8-15 deep inspirations with a 3-5-second breath hold, followed by 8-15 breaths against expiratory resistance, with 2-3 minutes of rest between sets.

    Participants received initial supervised instruction, and training parameters were reviewed and individually adjusted during weekly physiotherapy sessions.

  • Individualised Exercise Programme (Aerobic and Resistance Training)Other

    Participants received a four-week individually prescribed exercise programme combining aerobic and resistance training.

    Aerobic exercise consisted of walking or cycling for at least 30 minutes per day, five days per week, at moderate-to-vigorous intensity (70-85% of age-predicted maximum heart rate).

    Resistance training targeted major muscle groups, comprising 2-4 sets of 8-12 repetitions, twice weekly, initially at 40-60% of one-repetition maximum.

    Exercises were performed independently at home or in community settings, with individual prescriptions reviewed during weekly physiotherapy sessions.

  • Patient Education ProgrammeOther

    Participants received a four-week patient education programme addressing respiratory anatomy and physiology, potential respiratory consequences of breast cancer treatment, and the benefits of physical exercise for cardiorespiratory function and functional capacity.

    Education was delivered during weekly face-to-face physiotherapy sessions and supported by printed educational materials.

Where is the study taking place?

The record lists 1 site in Spain. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Recruitment Rate (time frame: During the recruitment period). The study lists 7 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 26 Oct 2026.
