“…In line with this thought studies in stroke patients and low back pain patients showed a higher reliability in more challenging standing conditions (eyes-closed condition) compared to an easier condition (eyes-open condition). 15,25 The iPod Touch used in the present study was fixed near the lower back around L3. Placement at the lower back is frequently used to determine gait and postural parameters due to the location near the body's center mass.…”

Accelerometer-based assessments can identify elderly with an increased fall risk and monitor interventions. Smart devices, like the iPod Touch, with built-in accelerometers are promising for clinical gait and posture assessments due to easy use and cost-effectiveness. The aim of the present study was to establish the validity and reliability of the iPod Touch for gait and posture assessment. Sixty healthy participants (aged 18-75 years) were measured with an iPod Touch and stand-alone accelerometer while they walked under single- and dual-task conditions, and while standing in parallel and semi-tandem stance with eyes open, eyes closed and when performing a dual task. Cross-correlation values (CCV) showed high correspondence of anterior-posterior and medio-lateral signal patterns (CCV's ≥ 0.88). Validity of gait parameters (foot contacts, index of harmonicity, and amplitude variability) and standing posture parameters [root mean square of accelerations, median power frequency (MPF) and sway area] as indicated by intra-class correlation (ICC) was high (ICC = 0.85-0.99) and test-retest reliability was good (ICC = 0.81-0.97), except for MPF (ICC = 0.59-0.87). Overall, the iPod Touch obtained valid and reliable measures of gait and postural control in healthy adults of all ages under different conditions. Additionally, smart devices have the potential to be used for clinical gait and posture assessments.

[Purpose] The present study investigated what kind of effect smart phone use has on dynamic postural balance. [Subjects] The study subjects were 30 healthy students in their 20’s who were recruited from a University in Busan, Korea. [Methods] The present experiment was quasi-experimental research which measured the postural balance (Biodex) of subjects while they sent text messages via smart phones in the standing position with the eyes open, and while they used two-way SNS. [Results] There were significant differences between standing and the dual-task situations. Among dual tasks using smart phones, SNS using situations showed the highest instability. [Conclusion] The use of smart phones in less stable conditions such as while walking or in moving vehicles should be discouraged.

“…Low back pain is a musculoskeletal disease to cause problems in daily life if it lasts longer than three months (Sherafat et al, 2013). Although the cause of low back pain has not been clearly revealed yet, changes in the lumbar structure due to musculoskeletal damage and the biomechanical factors of surrounding tissues are considered to be the main causes of low back pain.…”

Effects of a static stretch using a load on low back pain patients with shortened tensor fascia lata

Stretch of tensor fascia lata (TFL) improves range of motion on hip and pelvis and it reported to help reduce low back pain. Accordingly, the purpose of this study was to investigate effects of static stretching using a load on TFL in patients with low back pain. Twenty three subjects were recruited according to the selection criteria. The subjects were randomly assigned to static stretching group (control, n=12), and a static stretching using a load group (experimental, n=11). All group performed stretching for 15 min (side for 50 sec per time and a rest for 30 sec) per day in the left side and the right, respectively, for 2 weeks. Before and after the intervention, all groups measured visual analogue scale (VAS), stand and reach test, and the Oswestry disability index (ODI). In the present results, we found that the experimental group showed significant differences in VAS, stand and reach test, and the ODI (P<0.05) in before and after the intervention. Therefore, static stretching using a load can be actively utilized for low back pain patients with shortened TFL.
