Effects of IMT on Cardiopulmonary Endurance and Functional Mobility in KOA (IMT)

25. august 2026 opdateret af: Riphah International University

Inspiratory Muscle Training as an Adjunct to Standard Care: Effects on Cardiopulmonary Endurance and Functional Mobility in Knee Osteoarthritis

The purpose of the study is to investigate whether adding Inspiratory Muscle Training (IMT) to the usual treatment of patients with knee osteoarthritis improves their cardiopulmonary endurance and functional mobility more than standard care alone.

Detaljeret beskrivelse

Knee osteoarthritis (KOA) is a common degenerative joint disorder associated with pain, stiffness, reduced mobility, and decreased physical activity. Reduced activity levels often result in impaired cardiopulmonary fitness and decreased aerobic capacity. Previous evidence suggests that individuals with severe KOA exhibit diminished inspiratory muscle strength and lower exercise tolerance. Inspiratory Muscle Training (IMT) strengthens respiratory muscles and improves ventilatory efficiency. IMT is a technique in which a person breathes in against resistance using a special device such as POWERbreathe to make the breathing muscles stronger. Since conventional rehabilitation primarily focuses on pain reduction and lower limb strengthening, incorporating IMT may provide additional benefits without imposing extra stress on the knee joint. This study aims to compare conventional KOA treatment combined with IMT against conventional treatment combined with sham IMT over a six-week intervention period.

Våben og indgreb

Deltagergruppe / Arm
Intervention / Behandling
Eksperimentel: Inspiratory Muscle Training (IMT) + Conventional Knee OA Physiotherapy
Participants will receive conventional knee osteoarthritis physiotherapy twice weekly for 6 weeks along with Inspiratory Muscle Training (IMT) using a POWERbreathe device. IMT will consist of 30 quick breaths twice daily at approximately 50% of baseline maximal inspiratory pressure (MIP), progressively increased up to 35 breaths according to patient tolerance. Conventional treatment includes knee isometric exercises, open-chain strengthening exercises, static stretching, and Maitland Grade I-II anterior-posterior mobilizations.
Enhed: POWERBREATH

The POWERBREATH devices utilize calibrated resistance valves to force your breathing muscles to work harder, which naturally builds their power, stamina, and efficiency. IMT through POWERbreathe

  • 30 quick breaths two times a day at an adjustable resistance (equivalent to∼50% of (baseline) MIP).
  • Increased up to 35 breaths as per patient's tolerance.
Sham-komparator: Sham IMT + Conventional Knee OA Physiotherapy
Participants will receive conventional knee osteoarthritis physiotherapy twice weekly for 6 weeks along with sham inspiratory muscle training using a POWERbreathe device. Sham training will consist of 60 slow breaths once daily at load setting zero (approximately 15% of baseline MIP). The load adjuster will be fixed with adhesive tape to prevent resistance progression. Conventional treatment will be identical to the experimental group
Enhed: SHAM IMT
  • 60 slow breaths once daily at a load setting of 0 (corresponding to∼15% (baseline) MIP).
  • Training load adjustment was prevented using sticky tape applied to the device's load adjuster.

Tidsramme
Visual Analogue Scale (VAS)
Tidsramme: : Baseline, Week 3, Week 6
Pain intensity was measured using the Visual Analog Scale (VAS), with scores ranging from 0 (no pain) to 10 (worst imaginable pain). The minimum possible score is 0, the maximum possible score is 10, and higher scores represent greater pain intensity (worse outcome).

Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) Total Score: The WOMAC is a self-reported questionnaire assessing pain, stiffness, and physical function in individuals with osteoarthritis. The total score ranges from 0 to 96, where 0 indicates no symptoms or functional impairment and 96 indicates the most severe symptoms and functional impairment. Higher scores indicate a worse outcome.
