Inspiratory Muscle Training in Patients With Autonomic Neuropathic


This study describes a controlled randomized clinical trial to evaluate the effect of inspiratory muscle training in patients with diabetic autonomic neuropathy.

Study Type

  • Study Type: Interventional
  • Study Design
    • Allocation: Randomized
    • Intervention Model: Single Group Assignment

Detailed Description

The diabetic autonomic neuropathy (NAD) is a common complication of diabetes mellitus (DM), both of the type 1 diabetes mellitus (DM1) as of the type 2 diabetes mellitus (DM2). The results of this study, would help to reveal the degree of commitment generated by NAD in respiratory muscle strength, can also enable the development of a new therapeutic approach, such non-pharmacological (respiratory muscle training), with a view to improve the respiratory muscle strength and alleviate the autonomic dysfunction in these patients.


  • Other: Inspiratory muscle training (IMT)
    • IMT (30 min 7 times per week, for 8 weeks)
