Toe Clearance Rehabilitative Slippers for Older Adults With Fall Risk: A Randomized Controlled Trial.

Introduction: To evaluate fall-prevention rehabilitative slippers for use by self-caring, independent older adults.

Materials And Methods: This assessor-blinded, randomized, and controlled 1-year study included 59 self-caring, independent participants (49 women) who attended day services. The mean age of participants was 84.

Probing spatial heterogeneity in silicon thin films by Raman spectroscopy.

Raman spectroscopy is a powerful technique for revealing spatial heterogeneity in solid-state structures but heretofore has not been able to measure spectra from multiple positions on a sample within a short time. Here, we report a novel Raman spectroscopy approach to study the spatial heterogeneity in thermally annealed amorphous silicon (a-Si) thin films. Raman spectroscopy employs both a galvano-mirror and a two-dimensional charge-coupled device detector system, which can measure spectra at 200 nm intervals at every position along a sample in a short time.
