Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
The study utilizes TIS, BBS and TUG to assess balance, FGA to evaluate gait performance, and MIP and MEP to measure respiratory function. Assessments are conducted before and after the intervention to evaluate changes resulting from the treatment.
Eligible participants are individuals with subacute stroke (onset within 1-6 months), an MMSE-K score of 24 or higher, and the ability to walk at least 6 meters with or without an assistive device. Exclusion criteria include conditions prohibiting the Valsalva maneuver (e.g., glaucoma, aneurysm, pulmonary hypertension), acute respiratory infections, severe cognitive or language impairments, prior inspiratory muscle training within the past six months, unstable medical conditions, and neurological or musculoskeletal disorders affecting gait and balance.
This study aims to determine whether the combined application of IMT and ADIM enhances functional recovery, improves postural control, and promotes better respiratory health in stroke patients. The findings may contribute to the development of more effective rehabilitation strategies for improving quality of life in individuals recovering from stroke.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Inspiratory Muscle Training (IMT) with Abdominal Drawing-In Maneuver (ADIM) Group
participants recieve in IMT using a threshold resistance device, starting at 30% of maximal inspiratory pressure and progressively increasing to 60% over four weeks. The ADIM is performed with verbal and manual guidance to ensure correct deep abdominal muscle engagement. Sessions are conducted five times per week for four weeks, with each session lasting 40 minutes (20 minutes for each intervention).
Inspiratory Muscle Training (IMT) with Abdominal Drawing-In Maneuver (ADIM) training
ADIM aims to enhance trunk stability by selectively activating the transversus abdominis. Participants begin in a supine position and practice drawing in their abdomen toward the spine while maintaining a stable trunk and pelvis. A therapist provides verbal instructions and manual guidance to ensure proper muscle activation.
IMT is performed using the Threshold RMT device (IMT, GH INNOTEK, Busan, South Korea). Participants wear a nose clip and start with 30% of Maximal Inspiratory Pressure (MIP), gradually increasing by 10% per week to reach 60% MIP by the final week. Each session consists of five sets of 10-15 repetitions, with a one-minute rest between sets.
Sham Inspiratory Muscle Training(IMT) with Abdominal Drawing-In Maneuver(ADIM) Group
participants recieve simulated IMT with minimal resistance while performing the same ADIM as the experimental group. This design ensures that any effects observed can be attributed to inspiratory muscle training rather than ADIM. Sessions are conducted five times per week for four weeks, with each session lasting 40 minutes (20 minutes for each intervention).
Sham Inspiratory Muscle Training (IMT) with Abdominal Drawing-In Maneuver (ADIM) training
Sham IMT with ADIM training performs the same ADIM protocol as the IMT with ADIM training but undergoes IMT with minimal resistance (0 cmH₂O) to prevent actual muscle strengthening. This design ensures that the effects observed can be attributed to IMT rather than ADIM.
