ObjectivesWhile the health and well-being benefits of physical activity are recognised, people with multiple sclerosis (MS) often face greater barriers than the general population. The Nintendo Wii potentially offers a fun, convenient way of overcoming some of these. The aim was to test the feasibility of conducting a definitive trial of the effectiveness and cost-effectiveness of Mii-vitaliSe; a home-based, physiotherapist-supported Nintendo Wii intervention.DesignA single-centre wait-list randomised controlled study.SettingMS service in secondary care.ParticipantsAmbulatory, relatively inactive people with clinically confirmed MS.InterventionThirty participants were randomised to receive Mii-vitaliSe either immediately (for 12 months) or after a 6-month wait (for 6 months). Mii-vitaliSe consisted of two supervised Nintendo Wii familiarisation sessions in the hospital followed by home use (Wii Sports, Sports Resort and Fit Plus software) with physiotherapist support and personalised resources.OutcomesIncluded self-reported physical activity levels, quality of life, mood, self-efficacy, fatigue and assessments of balance, gait, mobility and hand dexterity at baseline, 6 and 12 months. Interviews (n=25) explored participants’ experiences and, at study end, the two Mii-vitaliSe facilitators’ experiences of intervention delivery (main qualitative findings reported separately).ResultsMean (SD) age was 49.3 (8.7) years, 90% female, with 47% diagnosed with MS <6 years ago and 60% new to active gaming. The recruitment rate was 31% (95% CI 20% to 44%). Outcome data were available for 29 (97%) at 6 months and 28 (93%) at 12 months. No serious adverse events were reported during the study. Qualitative data indicated that Mii-vitaliSe was well-received. Mean Wii use across both groups over the initial 6-month intervention period was twice a week for 27 min/day. Mean cost of delivering Mii-vitaliSe was £684 per person.DiscussionMii-vitaliSe appears acceptable and a future trial feasible and warranted. These findings will inform its design.Trial registrationISRCTN49286846

Defecatory disorders in children, including chronic constipation (CC) and fecal incontinence (FI), are common conditions worldwide and have a significant impact on children, their families, and the healthcare system. Anorectal manometry (ARM) and high‐resolution anorectal manometry (HRAM) are relatively novel tools for the assessment of anal sphincter function and rectal sensation and have contributed significantly to improving the understanding of the anorectum as a functional unit. ARM has been recognized as the investigation of choice for adults with symptoms of defecation disorders, including fecal incontinence (FI), evacuation difficulties, and constipation. Although it is the gold standard tool in adults, it has yet to be formally accepted as a standardized diagnostic tool in the pediatric age, with limited knowledge regarding indications, protocol, and normal values. ARM/HRAM is slowly becoming recognized among pediatricians, but given that there are currently no agreed guidelines there is a risk that will lead to diversity in practice. The British Society of Paediatric Gastroenterology, Hepatology and Nutrition (BSPGHAN)—Motility Working Group (MWG) therefore has taken the opportunity to provide guidance on the use of ARM/HRAM in children with CC and/or FI.

Aerosols of nedocromil sodium labelled with 99Tcm were delivered on 20 separate occasions to healthy male volunteers. Planar and single photon emission computerized tomography (SPECT) gamma scintigraphy were immediately performed to assess the pulmonary regional distribution of delivered aerosol. On a separate occasion volunteers were imaged using X-ray computed tomography (CT). Alignment of SPECT and CT images was performed using marked anatomical features and the anterior and lateral skin outlines. CT images provided data for attenuation correction and were used to define the anatomical lung volume. Central to peripheral (CP) ratios of deposited activity were calculated from volumes of interest in coronal and transverse sections of the right lung. These were compared with CP ratios obtained from planar images obtained immediately following aerosol inhalation. Volumetric CP ratio correlated significantly with immediate planar CP ratio (p < 0.001). Analysis of deposition in the whole right lung was performed by separating the SPECT lung data into a series of thin concentric shells centred on the entry of the right main bronchus. Measures were defined for describing the variation of deposition density and cumulative total deposition with distance from the lung centre. These showed significant correlation with planar CP ratio (p < 0.001). SPECT analysis using CT is consistent with planar measures of aerosol deposition but offers a more complete quantification of aerosol penetration and absolute deposited activity within the whole lung. It is a valuable new tool for aerosol analysis.
