Abstract
BACKGROUND The growth and popularity of complementary physical therapies for Parkinson's disease (PD) attempt to fill the gap left by conventional exercises, which does not always directly target wellbeing, enjoyment and social participation. AIM To evaluate the effects of complementary physical therapies on motor performance, quality of life and falls in people living with PD. DESIGN Systematic review with meta-analysis. POPULATION Outpatients--adults diagnosed with idiopathic PD, male or female, modified Hoehn and Yahr scale I-IV, any duration of PD, any duration of physical treatment or exercise. METHODS Randomized controlled trials, non-randomized controlled trials and case series studies were identified by systematic searching of health and rehabilitation electronic databases. A standardized form was used to extract key data from studies by two independent researchers. RESULTS 1210 participants from 20 randomized controlled trials, two non-randomized controlled trials and 13 case series studies were included. Most studies had moderately strong methodological quality. Dancing, water exercises and robotic gait training were an effective adjunct to medical management for some people living with PD. Virtual reality training, mental practice, aerobic training, boxing and Nordic walking training had a small amount of evidence supporting their use in PD. CONCLUSION On balance, alternative physical therapies are worthy of consideration when selecting treatment options for people with this common chronic disease. CLINICAL REHABILITATION IMPACT Complementary physical therapies such as dancing, hydrotherapy and robotic gait training appear to afford therapeutic benefits, increasing mobility and quality of life, in some people living with PD.

Abstract
PURPOSE Robust registration of prone and supine colonie surfaces acquired during CT colonography may lead to faster and more accurate detection of colorectal cancer and polyps. Any directional bias when registering one surface to the other could precipitate incorrect anatomical correspondence and engender reader error. Despite this, non-rigid registration methods are often implemented asymmetrically, which could negatively influence the registration. We aimed to reduce directional bias and so increase robustness by adapting a cylindrical registration algorithm to be both symmetric and inverse-consistent. METHODS The registration task can be simplified by mapping both prone and supine colonie surfaces onto regular cylinders. Spatial correspondence can then be established in cylindrical space using the original surfaces' local shape indices. We implemented a symmetric formulation of the popular non-rigid B-spline image registration method in cylindrical space. A symmetric similarity measure computes the sum of squared differences between both cylindrical representations of prone-to-supine and supine-to-prone directions simultaneously. Inverse consistency of the transformation is enforced by adding an appropriately weighted penalty term to the optimisation function. RESULTS We selected 8 CT colonography patient cases with marked variation in luminal distension and surface morphology. We randomly allocated 4 of these for tuning an optimal set of registration parameters and 4 for validation. The mean inverse-consistency error was reduced by 32% from 4.8mm to 3.2mm by the new symmetric formulation. The mean registration error improved from 8.2mm to 7.3mm for 330 manually chosen reference points on the 4 validation sets. CONCLUSIONS A symmetric formulation of prone and supine surface registration improves the quality of registration. Information from both prone-to-supine and supine-to-prone directions helps enforce convergence towards a more accurate solution due to reduced directional bias. A more robust and accurate registration will facilitate interpretation of CT colonography and has the potential to improve existing computer-aided detection methods.

Abstract
We discuss laser cooling opportunities in atomic erbium, identifying five J ? J + 1 transitions from the 4f126s2 3H6 ground state that are accessible to common visible and near-infrared continuous-wave tunable lasers. We present lifetime measurements for the 4f11(4Io 15/2)5d5/26s2 (15/2, 5/2)7o state at 11888 cm-1 and the 4f11(4Io 13/2)5d3/26s2 (13/2, 5/2)7o state at 15847 cm-1, showing values of 20 +/- 4 micros and 5.6 +/- 1.4 micros, respectively. We also present a calculated value of 13 +/- 7 s-1 for the transition rate from the 4f11(4Io 15/2)5d3/26s2 (15/2, 3/2)7 o state at 7697 cm-1 to the ground state, based on scaled Hartree-Fock energy parameters. Laser cooling on these transitions in combination with a strong, fast (5.8 ns) laser cooling transition at 401 nm, suggest new opportunities for narrowband laser cooling of a large-magnetic moment atom, with possible applications in quantum information processing, high-precision atomic clocks, quantum degenerate gases, and deterministic single-atom doping of materials.

Abstract
This paper promotes the concept of active models in image-guided interventions. We outline the limitations of the rigid body assumption in image-guided interventions and describe how intraoperative imaging provides a rich source of information on spatial location of anatomical structures and therapy devices, allowing a preoperative plan to be updated during an intervention. Soft tissue deformation and variation from an atlas to a particular individual can both be determined using non-rigid registration. Established methods using free-form deformations have a very large number of degrees of freedom. Three examples of deformable models--motion models, biomechanical models and statistical shape models--are used to illustrate how prior information can be used to restrict the number of degrees of freedom of the registration algorithm and thus provide active models for image-guided interventions. We provide preliminary results from applications for each type of model.

Abstract
Current practices regarding in-patient strengthening exercise prescription following anterior cruclate ligament (ACL) reconstruction are scarcely addressed in the literature and remain unreported for Australian hospitals. An observational, questionnaire-based study was used to Investigate in-patient quadriceps strengthening practices in Australian hospitals after ACL reconstruction. Questionnaires were returned by 248 hospitals (76% response rate) and of these 88 hospitals reported performing ACL reconstructions. These hospitals were surveyed to determine the types of quadriceps strengthening exercises prescribed during the in-patient period. Information was sought regarding routine management strengthening practices. A variety of quadriceps exercises such as static quadriceps contractions (SQC), straight leg raises (SLR) and inner range quadriceps (IRQ) were frequently prescribed, although no standard practice currently exists. Static quadriceps exercises were prescribed by 91% of hospitals surveyed, IRQ exercises were used by 30%, and 49% reported using SLR exercises. Current literature tends to support the performance of SQC and SLR exercises during the early postoperative period following ACL reconstruction. Conversely, current clinical practice is incongruent with regard to the scientific recommendations for IRQ performance.

Abstract
UNLABELLED Eutectic mixture of local anaesthetics (EMLA) cream is used routinely as a local anaesthetic prior to venepuncture in children. Despite this, however, a significant proportion of children will still be distressed. Cognitive-behavioural interventions, such as distraction by breathing and blowing exercises, have been used and found to be helpful as alternative coping strategies. There is, however, a paucity of data regarding effectiveness. We have evaluated the efficacy of distraction therapy as a coping strategy before and during venepuncture, and in these children evaluated the need for EMLA using a prospective, randomized, double-blind, placebo-controlled clinical trial. Twenty-eight children attending for venepuncture were recruited, median age 6 y (range 4-8 y), and randomly allocated to receive either EMLA or a placebo cream. All were given distraction therapy prior to and during the procedure by a play specialist. Venepuncture was carried out by one investigator. A modified paediatric pain assessment chart was used for objective pain score at the end of the procedure. After one exclusion, the treatment group (17 children) and the placebo group (10 children) were similar: median age of 6 and 7 y (range 4-8), median baseline and post-procedure heart rate and oxygen saturation. The median (interquartile range) for total pain score in the treatment group was 1 (0 to 4.5) and in the control group 1 (0 to 2.3). There was no significant difference in pain score between the two groups (Mann-Whitney test, p = 0.7). The 95% confidence interval for the difference in pain score was -1.0 to +3.0. CONCLUSIONS The low pain score in both groups suggests the effectiveness of distraction therapy, although factors such as skill of the operator and previous experience of the patient group are of relevance. There was no significant difference in the pain score between the EMLA and placebo groups, suggesting that in this age group if carefully selected children receive distraction during venepuncture EMLA may not be necessary.
