Incentive Spirometry With and Without Transcutaneous Electric Diaphragmatic Stimulation in Post-mastectomy Patients
Sponsor: University of Lahore
Summary
This randomized clinical trial will compare the effects of incentive spirometer therapy with and without transcutaneous electrical diaphragmatic stimulation (TEDS) in females who have undergone mastectomy. The study will include females aged 30 to 48 years who have undergone unilateral simple or radical mastectomy following breast cancer and are at least 3 months after surgery. Participants will be randomly assigned to one of two treatment groups. Participants in one group will receive conventional physiotherapy along with transcutaneous electrical diaphragmatic stimulation and incentive spirometer training. Participants in the other group will receive conventional physiotherapy and incentive spirometer training without TEDS. Treatment will be provided over 4 weeks. The study will evaluate changes in breathing-related symptoms, functional capacity, lung function, and quality of life. These outcomes will be assessed using a dyspnea index, Timed Up and Go test, pulmonary function testing (spirometry), and the Short Form-36 health survey. Assessments will be performed at baseline and after 4 weeks of treatment. The study aims to determine whether adding transcutaneous electrical diaphragmatic stimulation to incentive spirometer therapy provides additional benefits for post-mastectomy females.

Conditions
Interventions
Transcutaneous Electrical Diaphragmatic Stimulation
Transcutaneous electrical diaphragmatic stimulation (TEDS) will be applied using surface electrodes placed over the lower rib cage. Electrical stimulation will be delivered using a portable electrical stimulation unit, with intensity adjusted to produce a visible or palpable diaphragmatic contraction without discomfort. TEDS will be provided to participants in the experimental group in addition to incentive spirometer training and conventional physiotherapy.
Incentive Spirometer
Participants will perform incentive spirometer breathing exercises in a half-lying position at approximately 45 degrees. The protocol describes repeated deep breaths with an inspiratory hold. Incentive spirometer training will be provided to both treatment groups during the 4-week intervention period, in addition to conventional physiotherapy.
Conventional Physiotherapy
Conventional physiotherapy will be provided to both groups and will include diaphragmatic breathing exercises, airway clearance exercises, circulatory exercises, thoracic expansion exercises, and postural awareness exercises. The conventional therapy component is described as a 20-minute session and will be provided four times per week for 4 weeks.
