    Exploring the feasibility of a music-assisted relaxation intervention to assist with the initiation of non-invasive ventilation in people with Motor Neuron Disease

    Background: Transitioning to non-invasive ventilation (NIV) can cause anxiety in people with Motor Neuron Disease (MND), which may reduce adherence rates. Music therapy has demonstrated positive effects with mechanical (invasive) ventilation. Method: This feasibility study examined the effects of music-assisted relaxation (MAR) on NIV adherence, anxiety, and quality of life for people with MND. Data were collected at baseline, 7-days post, and 3-months post NIV implementation. Results: Of 18 consenting participants, 15 chose the MAR condition. Results suggested that supporting NIV transition within the first 7 days may be advantageous for long-term adherence. No effects were found for anxiety or quality of life. Limitations included small sample size, lack of an adequate control, and possible ceiling effects on the instruments used. Qualitative data indicated most participants considered the relaxing and distracting effects of MAR were useful. Conclusions: In this small sample, we found some demand for and acceptability of a music-based intervention in this setting. Participants reported differing experiences of using MAR, and there were technical and logistical issues regarding timely and accessible provision of a MAR intervention within the treatment trajectory of NIV implementation. Conflicting quantitative and qualitative data support the need for mixed method research in this area.

    Light sensors for objective light measurement in ambulatory polysomnography

    Ambulatory polysomnography (PSG) does not commonly include an objective measure of light to determine the time of lights off (Loff), and thus cannot be used to calculate important indices such as sleep onset latency and sleep efficiency. This study examined the technical specifications and appropriateness of a prototype light sensor (LS) for use in ambulatory Compumedics Somte PSG.Two studies were conducted. The first examined the light measurement characteristics of the LS when used with a portable PSG device, specifically recording trace range, linearity, sensitivity, and stability. This involved the LS being exposed to varying incandescent and fluorescent light levels in a light controlled room. Secondly, the LS was trialled in 24 home and 12 hospital ambulatory PSGs to investigate whether light levels in home and hospital settings were within the recording range of the LS, and to quantify the typical light intensity reduction at the time of Loff. A preliminary exploration of clinical utility was also conducted. Linearity between LS voltage and lux was demonstrated, and the LS trace was stable over 14 hours of recording. The observed maximum voltage output of the LS/PSG device was 250 mV, corresponding to a maximum recording range of 350 lux and 523 lux for incandescent and fluorescent light respectively. At the time of Loff, light levels were within the recording range of the LS, and on average dropped by 72 lux (9-245) in the home and 76 lux (4-348) in the hospital setting. Results suggest that clinical utility was greatest in hospital settings where patients are less mobile. The LS was a simple and effective objective marker of light level in portable PSG, which can be used to identify Loff in ambulatory PSG. This allows measurement of additional sleep indices and support with clinical decisions.
