“…A black mark was fixed on the wall 12.8m from the participant at eye level in order to stabilize the visual focus during the measurements. In the study of Piirainen et al [29] COP maximal displacement in the anterior direction showed the greatest differences between young and elderly participants. This parameter was therefore chosen for further analysis also in the present study and the average of four perturbations was calculated from the anterior direction with the two speeds, fast anterior perturbation (FAP) and slow anterior perturbation (SAP).…”

“…We deliberately sought to study a wide-ranging sample of ordinary people who were not elite athletes. It has been suggested previously that the control strategy may change during ageing [9] which may lead to different neuromuscular responses during balance perturbations [29]. This may also cause some differences in training adaptations between young and elderly participants, which may explain the quite large variations in dynamic balance control in both pre-and post-tests.…”

“…In sports, the standing limb in the kicking action in soccer and taekwondo is important to ensure stability needed for successful execution [25,35]. From an injury prevention perspective, balance deficit that occurs immediately after anaerobic stress and fatigue could affect sports performance and might increase the probability of injuries [29,32].…”

SummaryStudy aim: The aim of this study was to evaluate the effects of training while wearing socks differing in compression level (clinical, sub-clinical, regular) on performance of static and dynamic balancing and agility tasks in healthy, physically active people. We sought to understand whether socks with different compression properties supported postural regulation and agility task performance by enhancing somatosensory perception, unskewed by specific age range effects. Material and methods: Participants comprised 61 adults aged 18-75 years, divided into three groups (two experimental groups wearing clinical or sub-clinical level compression socks, and one control group wearing regular non-compression socks during training). An 8-week (2 × 1h per week) intervention programme was administered to train static and dynamic balance and postural control, leg strength and agility. Results: A mixed model ANOVA revealed no differences in static and dynamic balance and postural control and agility performance between clinical, sub-clinical, and control groups before and after training. All groups significantly improved their test performance, suggesting that training had some benefit on motor performance. Conclusions: These results raised interesting questions requiring further investigation to examine the effects of wearing socks (with and without different levels of compression) on motor behaviours in specific groups of elderly vs. young participants, in physically active vs. less physically active people, and in performance settings outside standardized laboratory tests to study applications in natural performance environments.

“…Regarding aging, the work of Piirainen et al (2013) monitored EMG signal of muscles SO, TA and Gastrocnemius of 9 young adults and 10 older adults in the recovery of postural equilibrium after a disturbance in the anterior-posterior and posterioranterior directions. The authors noted that, due to aging a decrease in postural control occurs.…”

Human posture control is a sophisticated process involving the relationship among multiple joints, muscle groups and environment. The aim of this study is to show how the balance perturbation (in posterioranterior direction) leads to a stretching reflexion on the tibialis anterior (TA) muscle. A case study that involved a male participant with 23 years old. To disturb the participant's balance, it has been employed a specially plataform designed with dimensions 1.5 m by 1.5 m with movement of 5 mm of amplitude on a total time of 3 ms along the axis coinciding with participant's anterior-posterior axis. Soleus (SO) and TA electromyography signal (EMG) has been recorded. Perturbation in the equilibrium was delivered in the posterior-anterior direction. The first event observed was the pre-activation of the TA muscle that leads a reduction in the SO muscle activation, due the stretch reflex at TA.

“…The instrument that was used in this study to measure the balancing abilities of the patient was the balance-measuring instrument (BT-4; Hur Lab, Koarla, Finland), which could evaluate the static and dynamic balancing abilities (Piirainen et al, 2013). The balancing equipment that was used for the test had a 100-Hz sampling rate and a rectangular shape.…”

The purpose of this study was to determine the influence of the proprioceptive neuromuscular facilitation (PNF) exercise programs for idiopathic scoliosis with a female patient in the early 20s in terms of her spinal curve and balancing abilities. The study subject was selected among 21-year-old female college students. There were no particular activities that the subject could not perform, but patient complained of difficulty in maintaining the standing position for a prolonged time. Patient chest X-ray results showed S-shaped curves tilted towards the left or right in the lumbar spine, thoracic spine, and cervical spine areas. The PNF exercise programs consists of seven therapeutic exercise programs, including home exercises considering the patients’ balancing abilities, the lateral symmetry of the spinal sway, the distortion, and the height of the pelvis and scapula bones. The programs last for 6 weeks and includes three sessions per week, with each session lasting for 30 min. Before and after the execution of the PNF exercise programs, the subject was monitored for the changes in her spinal sways through chest X-ray tests. Also, using a balance measurement instrument, the subject’s static and dynamic balancing abilities were tested. After executing the PNF exercise programs for 6 weeks, the spinal sways of the subject were corrected, and her static and dynamic balancing abilities were improved compared to the baseline values.
