Simple method for estimating low muscle mass in persons with bioelectrical impedance analysis measurement difficulties.

Bioelectrical impedance analysis cannot be used to measure muscle mass in some individuals. We aimed to determine cutoff values for low skeletal muscle mass index in sarcopenia diagnosis, based on the fat-free muscle mass index estimated using body fat percentage prediction equations, without relying on bioelectrical impedance analysis. The study included 564 residents from Wakasa, Fukui Prefecture, with a mean age of 76.

Association of knee joint performance and gait patterns with pain catastrophizing in patients with severe knee osteoarthritis: a cross-sectional study.

Background: Pain catastrophizing is linked to patient-reported outcomes in knee osteoarthritis (OA) patients, but its correlation with objective joint-level function (range of motion and strength) and gait patterns is unclear. This study examined the association between objective knee function, gait patterns, and pain catastrophizing in severe knee OA patients.

Combining transcranial direct current stimulation and peripheral electrical stimulation to improve upper limb function in a patient with acute central cord syndrome: a case report.

We report the immediate improvement of weakened muscles after combined treatment with transcranial direct current stimulation (tDCS) and peripheral electrical stimulation (PES) in a patient with acute central cord syndrome (CCS) who presented with severe upper limb motor dysfunction. A 70-year-old man sustained CCS with severe motor deficits in the left upper limb, which did not improve with conventional training until 6 days after injury. On the seventh day after the injury, the left upper limb was targeted with combined tDCS (1 mA for 20 minutes/day, anode on the right, cathode on the left) and PES (deltoid and wrist extensors, 20 minutes/day at the motor threshold), and his performance score immediately improved from 0 to 6 on the Box and Block test.
