Abstract:
Objective: To elucidate the outcome of an inspiratory muscle training (IMT) rehabilitation intervention on lung function, functional mobilization, balance, and peripheral muscle strength of the paretic side in subacute stroke patients.
Methods: This double-blind, randomized controlled trial study included patients with stable subacute stroke. For 8 weeks, the intervention group (n=16) received 40% intensity IMT while the control group (n=16) received 10% intensity. We assessed lung function (spirometer) before and after the intervention, as well as pulmonary muscle strength (Micro Respiratory Pressure Meter-RPM), quadriceps strength (hand held-dynamometer), grip strength (Jamar), walking speed (10-meter walk test), balance (Berg Balance Scale-BBS), and functional mobilization (sit to stand test).
Result: There were significant difference comparing intervention group to controls after IMT for FVC% (p
Conclusion: IMT improved lung function, functional mobilization, handgrip strength, and quadriceps strength on the paretic side of a subacute stroke patient, and is expected to improve functional status and allow the patient to participate in community activities. IMT exercise can be included in the rehabilitation program for subacute stroke patients.
