Other Medical Conditions

 

Dyspnoea is a common feature of many disorders. Its source may be respiratory, cardiovascular, neuromuscular, or even psychological. Regardless of its origin, a common denominator in dyspnoea is inspiratory muscle weakness.

Specific training of the inspiratory muscles has been demonstrated to increase their strength, resistance to fatigue and reduce exertional dyspnoea.

Because Inspiratory Muscle Training influences dyspnoea directly at a cortical level, it is also helpful for managing other conditions where dyspnoea is present, in addition to COPD and asthma. These include:

• Elderly people¹⁸ (with non-specific dyspnoea Copestake & McConnell, 1995)
• Neuromuscular disease¹
• Parkinson's disease²
• Prior-polio³
• Spinal cord injury⁴
• Sleep apnoea and snoring¹⁹ (Heijdra et al., 1996)
• Exercise-induced paradoxical vocal fold motion¹³

Inspiratory muscle training has also been shown to be helpful in other medical conditions, including:

• Muscular dystrophy⁵
• Multiple Sclerosis⁶
• Voice and speech disorders⁷
• Postoperative pulmonary complications⁸
• Restrictive thoracic disease⁹
• Severe chronic pulmonary hypertension¹⁰
• Inspiratory stridor¹¹
• Duchenne muscular dystrophy¹²
• Tetraplegia¹⁴
• Myasthenia gravis¹⁵
• Bronchiectasis¹⁶
• Chronic hemodialysis¹⁷
