简要总结
This randomized controlled trial will investigate whether adding diaphragmatic breathing training to conventional physiotherapy improves trunk control and postural stability in individuals with chronic stroke compared with conventional physiotherapy alone. Forty participants with chronic unilateral stroke will be randomly allocated in a 1:1 ratio to either an experimental group receiving diaphragmatic breathing training plus conventional physiotherapy or a control group receiving conventional physiotherapy alone. The intervention will be provided three times per week for six weeks.
详细描述
The study will use a prospective, two-arm, parallel-group randomized controlled design. Forty individuals with chronic unilateral stroke will be recruited and randomly allocated to either an experimental group or a control group in a 1:1 ratio.
The experimental group will receive standard diaphragmatic breathing training in addition to conventional physiotherapy. The control group will receive the same conventional physiotherapy program without diaphragmatic breathing training.
Both groups will receive three treatment sessions per week for six weeks, for a total of 18 sessions.
Trunk control and postural stability will be assessed at baseline and after completion of the six-week intervention. Trunk control will be assessed using the Trunk Impairment Scale, while postural stability will be assessed using the Biodex Balance System. Functional mobility will be assessed using the Timed Up and Go test.

研究组 & 干预措施
Diaphragmatic Breathing Training and Conventional Physiotherapy
Participants will receive conventional physiotherapy combined with standard diaphragmatic breathing training. Diaphragmatic breathing training will involve slow nasal inspiration emphasizing abdominal/lower rib cage expansion, followed by slow controlled oral expiration while minimizing upper chest and shoulder movement. Training will be provided for approximately 10-15 minutes per session, three sessions per week for six weeks.
干预措施: Diaphragmatic Breathing Training and Conventional Physiotherapy (Behavioral)
Conventional Physiotherapy
Participants will receive the same standardized conventional physiotherapy program as the experimental group without diaphragmatic breathing training. Treatment will be provided three sessions per week for six weeks.

结局指标
主要结局
Trunk Impairment Scale
时间窗: Baseline (Week 0) and post-intervention (Week 6)
Trunk control will be assessed using the original 17-item Trunk Impairment Scale, which evaluates static sitting balance, dynamic sitting balance, and coordination. Total scores range from 0 to 23, with higher scores indicating better trunk control.
Trunk Impairment Scale (TIS)
时间窗: Baseline (Week 0) and post-intervention (Week 6)
Trunk control will be assessed using the original 17-item Trunk Impairment Scale, which evaluates static sitting balance, dynamic sitting balance, and coordination. Total scores range from 0 to 23, with higher scores indicating better trunk control.
Biodex Postural Stability
时间窗: Baseline (Week 0) and post-intervention (Week 6)
Postural stability will be assessed using the Biodex Balance System. The selected postural stability index will be recorded under standardized testing conditions, with the same test configuration used at baseline and post-intervention.
次要结局
- Timed Up and Go (TUG)(Baseline (Week 0) and post-intervention (Week 6))
