Variability in clinical presentation among patients with neck pain disorders, in relation to symptom severity and the effect of the disorder on their physical and psychological function, has not been well documented. The present study examined the variability in pain intensity, physical and emotional or cognitive function in patients with non-acute, non-traumatic neck pain, and the extent to which these factors are associated at the time of referral for physiotherapy treatment. ⋯ The results highlight the variability between patients with neck pain, in relation to pain intensity and the effect of the disorder on physical and psychological function. Identifying the specific effects of the neck pain disorder in individual cases is important when defining the treatment objectives and selecting measures of treatment response.

Manual hyperinflation is a physiotherapy technique that improves static compliance and mobilizes secretions, but has the potential to alter haemodynamic function. The aim of the present study was to investigate the effects of manual hyperinflation on haemodynamic function in a healthy animal model, without the usual confounding effects inherent in an heterogeneous intensive care population. ⋯ Significant haemodynamic changes occurred in this animal model. The increased intrathoracic pressure, applied for an increased period during inspiration, decreased cardiac output with compensatory vasoconstriction evident by the increased systemic vascular resistance and mean arterial pressure. The results suggest that there may be a decrease in cardiac output after increased positive pressure in subjects with normal cardiac and respiratory function.

Randomized Controlled Trial Comparative Study Clinical Trial
An evaluation of a single chest physiotherapy treatment on mechanically ventilated patients with acute lung injury.
Acute lung injury is a lung pathology that presents frequently on the intensive care unit. Chest physiotherapy, in the form of endotracheal suction, alternate side-lying and manual hyperinflation, is usually given to patients with this condition with the intention of removing retained pulmonary secretions and recruiting collapsed distal lung units. Despite this common practice there is insufficient research on the effects of chest physiotherapy in patients with acute lung injury being ventilated mechanically. The aim of the present study was to further understanding of the effects of three modes of treatment in chest physiotherapy in an acute lung injury patient group. ⋯ Patients with acute lung injury are notably complex to nurse and may require protracted physiotherapy intervention, which may take many forms. As de-recruitment was the single most important event that occurred in the present study population, a prescriptive chest physiotherapy approach to treating mechanically ventilated patients with acute lung should be questioned and adapted accordingly.

Randomized Controlled Trial Clinical Trial
A comparison of the effects of manual and ventilator hyperinflation on static lung compliance and sputum production in intubated and ventilated intensive care patients.
Lung hyperinflation is a technique used by physiotherapists to mobilize and remove excess bronchial secretions, reinflate areas of pulmonary collapse and improve oxygenation. Hyperinflation may be delivered by the ventilator or manually, by use of a manual resuscitation circuit, depending upon the respiratory and cardiovascular status of the patient. The effects of manual hyperinflation, with respect to excess bronchial secretions and static lung compliance, have been well-established. There is, however, only limited evidence as to the efficacy of ventilator hyperinflation as a physiotherapy treatment technique. The purpose of the present study was to compare the effects of manual hyperinflation and ventilator hyperinflation on static pulmonary compliance and sputum clearance in stable intubated and ventilated patients. ⋯ Hyperinflation as part of a physiotherapy treatment can be performed with equal benefit using either a manual resuscitation circuit or a ventilator. Both methods of hyperinflation improve static pulmonary compliance and clear similar volumes of pulmonary secretions.

The performance of manual hyperinflation by physiotherapists can be improved by the availability of a pressure manometer. The present study aimed to test whether these benefits could be maintained when the manometer is withdrawn and whether the availability of a manometer affects the pressures delivered under changing respiratory compliances. ⋯ The availability of a pressure manometer negates the influence of respiratory compliance on the achievement of target peak airway pressures during manual hyperinflation in the laboratory environment, however these benefits are not retained when feedback is withdrawn. Therefore, it is recommended that a pressure manometer should be routinely available during manual hyperinflation in clinical practice to optimize treatment safety and effectiveness.
