The Use of Action Observation and Imitation in the Treatment of Upper Limb Paresis Early After Stroke

Background: Evidence suggests that repetitive functional training might improve upper limb (UL) recovery following a stroke however, individuals with more severe paresis often find participating in such training difficult. There is therefore a need for new therapies that can “prime” the central nervous system for movement before commencing repetitive training. Primary Aim: To ascertain if a new therapy called “Observation with intent To Imitate” (OTI)+Motor Practice (MP) sufficiently enhanced UL recovery in individuals with moderate/severe paresis early after stroke to justify proceeding to subsequent dose finding (phase I) and efficacy (phase II) trials. Methods: Seventeen individuals with moderate/severe UL limb paresis 3 to 31 days following ischaemic/haemorrhagic stroke were recruited. Those who were able to imitate an action were randomly assigned to receive either OTI+MP in addition to conventional physical therapy (CPT) or CPT alone. Those appointed to the OTI+MP group received up to an hour of OTI+MP once a day, for 15 consecutive working days. The outcome measures used were the Motricity Index (MI) to ascertain the ability to voluntarily contract paretic muscle (strength), the Action Research Arm Test (ARAT) to assess function and adverse event monitoring. Results: Both groups significantly improved in UL strength and function but the addition of OTI+MP did not result in better outcomes than CPT alone (P=0.425, MI), (P=0.520, ARAT). No adverse events were recorded. Conclusion: The addition of OTI+MP to CPT did not significantly improve UL strength and function compared to CPT alone. There were however, more clinically important changes with a general trend to greater improvement witnessed within the OTI+MP group, indicating that some individuals may have benefited from the additional therapy. More studies are required to establish which stroke survivors are most likely to benefit from OTI+MP early after stroke before progressing to dose finding and efficacy trials

Approximate method for predicting the permanent set in a beam in vacuo and in water subject to a shock wave

An approximate method to compute the maximum deformation and permanent set of a beam subjected to shock wave laoding in vacuo and in water was investigated. The method equates the maximum kinetic energy of the beam (and water) to the elastic plastic work done by a static uniform load applied to a beam. Results for the water case indicate that the plastic deformation is controlled by the kinetic energy of the water. The simplified approach can result in significant savings in computer time or it can expediently be used as a check of results from a more rigorous approach. The accuracy of the method is demonstrated by various examples of beams with simple support and clamped support boundary conditions

Spectral variability of the particulate backscattering ratio

The spectral dependency of the particulate backscattering ratio is relevant in the fields of ocean color inversion, light field modeling, and inferring particle properties from optical measurements. Aside from theoretical predictions for spherical, homogeneous particles, we have very limited knowledge of the actual in situ spectral variability of the particulate backscattering ratio. This work presents results from five research cruises that were conducted over a three-year period. Water column profiles of physical and optical properties were conducted across diverse aquatic environments that offered a wide range of particle populations. The main objective of this research was to examine the behavior of the spectral particulate backscattering ratio in situ, both in terms of its absolute magnitude and its variability across visible wavelengths, using over nine thousand 1-meter binned data points for each of five wavelengths of the spectral particulate backscattering ratio. Our analysis reveals no spectral dependence of the particulate backscattering ratio within our measurement certainty, and a geometric mean value of 0.013 for this dataset. This is lower than the commonly used value of 0.0183 from Petzold\u27s integrated volume scattering data. Within the first optical depth of the water column, the mean particulate backscattering ratio was 0.010

Spectral backscattering properties of marine phytoplankton cultures

The backscattering properties of marine phytoplankton, which are assumed to vary widely with differences in size, shape, morphology and internal structure, have been directly measured in the laboratory on a very limited basis. This work presents results from laboratory analysis of the backscattering properties of thirteen phytoplankton species from five major taxa. Optical measurements include portions of the volume scattering function (VSF) and the absorption and attenuation coefficients at nine wavelengths. The VSF was used to obtain the backscattering coefficient for each species, and we focus on intra- and interspecific variability in spectral backscattering in this work. Ancillary measurements included chlorophyll-a concentration, cell concentration, and cell size, shape and morphology via microscopy for each culture. We found that the spectral backscattering properties of phytoplankton deviate from theory at wavelengths where pigment absorption is significant. We were unable to detect an effect of cell size on the spectral shape of backscattering, but we did find a relationship between cell size and both the backscattering ratio and backscattering crosssection. While particulate backscattering at 555 nm was well correlated to chlorophyll-a concentration for any given species, the relationship was highly variable between species. Results from this work indicate that phytoplankton cells may backscatter light at significantly higher efficiencies than what is predicted by Mie theory, which has important implications for closing the underwater and remotely sensed light budget
