Whilst attempts to identify ‘responders’ to airway clearance techniques in AECOPD have not been

successful to date,49 this does not exclude a role for the techinques in carefully selected patients in whom excessive sputum production or sputum retention are clinically important problems. Early mobilisation, which aims to prevent functional decline and facilitate hospital discharge, is a key element of physiotherapy management for AECOPD. This includes early ambulation, commenced within 24 hours of hospital admission, and may also include check details targeted strength training and goal-directed practice (eg, stair training) to achieve a safe discharge back to the community. There is some evidence to support the efficacy of this low-intensity exercise training as part of a broader package of care. A Cochrane review examined the impact of multidisciplinary interventions including

exercise programs to improve strength or function in acute medical inpatients aged 65 years or older.50 Of nine included trials, seven had a substantial proportion of participants with respiratory disease. There was a small but significant reduction in hospital length of stay in participants who received the package of care including early, low-intensity, exercise training (MD 1.08 days shorter in the intervention group, 95% CI 1.93 to 0.22). Mobility interventions that aim to facilitate discharge are considered to be standard care for people hospitalised with AECOPD. Early rehabilitation, which is a more intensive Ion Channel Ligand Library supplier approach than early mobilisation, may be applied during or after an AECOPD. Early rehabilitation applies the well-established tuclazepam principles of pulmonary rehabilitation to patients who are in the initial stages of recovery from an AECOPD. This includes the use of moderate-to-high intensity endurance training and/or strength

training. Initial studies suggested that this training approach is safe even in the early stages of hospitalisation, with no significant adverse events and no increase in markers of systemic inflammation.51 and 52 A Cochrane review including nine trials where rehabilitation was commenced either during or after treatment for an AECOPD showed a reduction in the odds of future hospital admission of 88% (pooled OR 0.22, 95% CI 0.08 to 0.58) and a reduction in the odds of death of 72% (OR 0.28, 95% CI 0.10 to 0.84).53 This systematic review provided the first robust evidence that early pulmonary rehabilitation could impact on mortality, which was a significant advance in the field and provided a strong rationale for its implementation into physiotherapy practice. Although the data supporting early rehabilitation presented in the Cochrane review showed clear and consistent effects,53 a recent trial suggests a more complex story.
