TL;DR: The four square step test is uniquely associated with multiple measures of mobility in older adults, suggesting lower extremity motor function is an important factor for mobility performance.

TL;DR: The development of a tolerable neuromuscular electrical stimulation protocol that induces skeletal muscle adaptations similar to those observed with sprint training is described, suggesting that NMES has the potential to bring the benefits of sprint exercise to individuals who are unable to tolerate traditional sprint training.

TL;DR: This article describes a paired-pulse transcranial magnetic stimulation protocol to quantify intracortical facilitation and short-interval intracordical inhibition of the lumbar paraspinal muscles, and an electromechanical tapping protocol to measure the amplitude of the short-latency stretch reflex.

TL;DR: Data from animals demonstrate that administering either testosterone or IGF-1 to cells of the central and peripheral motor system can increase cell excitability, attenuate atrophic changes, and improve regenerative capacity of motor neurons, and suggest that additional research is warranted along these lines.

TL;DR: The hypothesis that a single session of anodal transcranial direct current stimulation of the motor cortex would increase elbow flexion muscle strength and electromyographic amplitude in very old individuals was found to be false.
