The purpose of this study was to determine the role of somatosensory input to the sensory reference system in quiet standing. We applied vibration (0.5 mm amplitude, 1-60 Hz) to the triceps surae and the forefoot sole to stimulate the muscle spindles and the mechanoreceptors, respectively, and evaluated postural responses.

- Individuals with chronic low back pain (LBP) show changes in brain activity that affect their posture and coordination, highlighting the need to explore these connections further.
- A study involving 14 healthy participants measured their movements under three conditions: no pain, pain induced by stimulation, and no pain again, revealing significant changes in muscle activation and movement execution during the Pain condition.
- The findings linked specific brain activity (contingent negative variation) to the alterations in movement patterns caused by acute LBP, suggesting a pathway for future research into the neural mechanisms behind these changes.
The effects of low-intensity muscle training with heel-raises on dynamic balance associated with bilateral arm flexion were investigated in postmenopausal elderly women. Twenty-six elderly women were evenly grouped into training and control groups. Training group subjects performed 100 heel raises per day for 2 months.
