Behavioural modes of adherence to inspiratory muscle training in people with chronic obstructive pulmonary disease: a grounded theory study.

The participants' behavioural modes regarding adherence revealed patterns of both intended and unintended nonadherence. In particular, support offered by healthcare professionals should target people with unintended nonadherence and scepticism about the effects of IMT to maximise the possibility of adherence. Implications for rehabilitation When implementing inspiratory muscle training, healthcare professionals should be prepared to spend considerable time providing attention and support to participants who feel challenged during the execution of inspiratory muscle training. Support offered by healthcare professionals should target people with scepticism about the effects of inspiratory muscle training to maximise the possibility of adherence. Intended adherence to inspiratory muscle training appeared to be firmly rooted, which means that healthcare professionals can pay less attention to patients with strong intentions to ensure adherence.
