Purpose: This study aims to evaluate a new method for the five times sit to stand test (FTSST), crucial for addressing frailty in an aging population. It utilizes a smart insole for plantar pressure analysis and a marker-less motion capture device for head height analysis.

Materials And Methods: Thirty-five participants aged 50 years or older underwent FTSST assessment using three methods: manual measurement with a stopwatch (FTSST-M), plantar pressure analysis with smart insoles (FTSST-P), and head height analysis with a marker-less motion capture device (FTSST-H).

Article Synopsis
  • - Early rehabilitation after spinal surgery is crucial for recovery, and a newly developed robot-assisted gait training (RAGT) protocol was tested for its effects on patient outcomes and therapist experiences, demonstrating promising improvements in functional ambulation and patient satisfaction.
  • - The study involved collaboration with experienced physiatrists and physical therapists to create and refine the RAGT protocol, followed by a cross-sectional study with 32 patients and 5 therapists, which included five RAGT sessions.
  • - Results showed significant improvements in ambulation scores post-treatment and general satisfaction among both patients (for fear of falling) and physical therapists, with therapists noting varying levels of satisfaction regarding the treatment's impact on their work environment.

This cross-sectional study, conducted at a tertiary care hospital's rehabilitation clinic, aimed to validate Short Physical Performance Battery (SPPB) results obtained through plantar pressure analysis using commercial smart insoles (SPPB-SI) and to compare these results to manually acquired results by an experienced examiner (SPPB-M). This study included 40 independent-walking inpatients and outpatients aged 50 or older. SPPB-SI and SPPB-M were administered concurrently, with the smart insoles providing plantar pressure data that were converted into time-pressure curves.

YKL-40, a chitinase-3-like protein 1 (CHI3L1) or human cartilage glycoprotein 39 (HC gp-39), is expressed and secreted by various cell-types including macrophages, chondrocytes, fibroblast-like synovial cells and vascular smooth muscle cells. Its biological function is not well elucidated, but it is speculated to have some connection with inflammatory reactions and autoimmune diseases. Although having important biological roles in autoimmunity, there were only attempts to elucidate relationships of YKL-40 with a single or couple of diseases in the literature.
