“…CES activity was higher in the N-WC than in the S-WC. Previous studies have reported that neck muscle activity is lower in a neutral posture than in FHP [14,24] and that cervical muscle activity at rest is greater in elderly individuals than in young people [14,18,30]. Elderly individuals tend to have more FHP than younger individuals, and CES activity at rest may also be higher in the elderly.…”

“…Maximal voluntary contractions are particularly difficult for elderly individuals, especially maximal contractions of the cervical muscles [18,19]. Limited thoracic flexibility prevents many elderly individuals from performing true maximal voluntary contractions of the cervical muscles in a prone position [5,19].…”

Background: As the population ages, the number of elderly individuals using a wheelchair is increasing. A standard wheelchair with a vertical backrest (S-WC) pushes on a kyphotic spine and exacerbates forward head posture. Forward head posture limits cervical movement. We used a new wheelchair (N-WC) that does not exacerbate thoracic kyphosis. The N-WC does not have a flat backrest, but has a support belt for the thorax and pelvis. The purpose of this study was to compare head-neck angle, cervical range of motion, and cervical muscle activity in the N-WC and the S-WC in healthy elderly women. Methods: We measured head-neck alignment, trunk tilt angle, cervical muscle activity, and pressure distribution on the backrest. Data from 17 subjects were analyzed. Results: Head-neck angle was close to neutral in the N-WC. The trunk was tilted further back and the area over which pressure was distributed on the backrest was expanded in the N-WC. Cervical range of motion and cervical muscle activity during neck extension were significantly greater in the N-WC than in the S-WC, but during neck flexion, there was no significant difference between the wheelchairs. Conclusion: In the N-WC, head-neck alignment was close to the neutral posture because the wheelchair support belt accommodated kyphosis and did not push the spine forward, so cervical muscle activity may be reduced when at rest. These results suggest that the N-WC prevented forward head posture and improved cervical movement and muscle activity. (C) 2014 Elsevier Masson SAS and European Union Geriatric Medicine Society.

“…The musculoskeletal system can add to stability by using activation of both agonist and antagonist activity to stabilize the body [38]. Laughton and colleagues [39] have shown a correlation of muscle activity at the ankles with the short-term postural sway. Lord and colleagues [40] also reported an association of the increase in body sway with weakness at lower legs especially the ankle dorsiflexors [41].…”

Objective: Potential pain relief from foot pain can come from a shoe insert foot orthotic. This study assessed foot pressure distribution and balance in off the shelf foot orthotics versus a custom made foot orthotic compared to no orthotic. Methods:The subjects (8) were both men and women. The average age was 25.1 ± 2.8 years, the average weight was 68.8 ± 13.7 kg, and BMI 24.5 ± 6.4. Each patient was fit for both off the shelf and custom shoe insert foot orthotics and needed orthotics to reduce pain. Once fit, they were evaluated by standing and then walking 12 meters on a level surface while being monitored by a Tactilus Pressure Mapping system. Balance was also evaluated with a pressure platform during 8 balance tests. Results:With the subjects accomplishing quiet standing, the average pressure and peak pressure was shifted from the hind foot and forefoot to the mid foot when wearing foot inserts (p<0.05). During walking, the average pressure was significantly shifted from the forefoot and hind foot to the mid foot in both orthotic groups with the greatest reduction in forefoot pressure in the off the shelf orthotic group (p<0.05). This is especially seen when measuring the peak pressures on the foot, where, during standing the peak pressures on the fore foot were 20% higher with no orthotic than seen for the 2 orthotics tested here. Balance was best in the custom orthotic group while both orthotic groups had better balance than the no orthotic studies for the most difficult balance tests. Conclusion: At least in this small group of subjects, off the shelf foot orthotics help gait or balance but custom orthotics are better.
