This study investigates changes in the posture angles of the neck and trunk, together with changes in the muscle activation of users, at the start of and at 5, 10, and 15 minutes of smartphone use. Eighteen males participated in this study. Surface electromyography (EMG) and a digital camera were used to measure the muscle activation and angular changes of the neck and trunk of participants during smartphone use for a period of 16 minutes. Neck and trunk flexion significantly increased at 5, 10, and 15 minutes (p < 0.05) in comparison with the neck and trunk flexion of participants at the start of smartphone usage. The EMG activation and 10th%amplitude probability distribution function (APDF) values of the bilateral cervical erector spinae at 5-6, 10-11, and 15-16 minutes of usage (p < 0.05) were also significantly greater than at the start of usage. The EMG activation of the bilateral thoracic erector spinae and lower trapezius was significantly decreased at 5-6, 10-11, and 15-16 minutes of usage (p < 0.05). Smartphone use induced more flexed posture on the neck and trunk than other visual display terminal (VDT) work. Smartphone use also changed posture and muscle activation within a relatively short amount of time, just 5 minutes. Pain after 16 minutes of smartphone use was also observed. Thus, clinicians should consider the influences of smartphone use in posture and muscle activity in evaluation, intervention, and prevention of neck and trunk conditions.

Purpose: To observe the effects of whole-body vibration (WBV) training in conjunction with conventional physical therapy (PT) on joint-position sense (JPS), balance, and gait in children with cerebral palsy (CP). Methods: In this randomized controlled study, 24 children with CP were randomly selected either to continue their conventional PT or to receive WBV in conjunction with their conventional PT programme. Exposure to the intervention was intermittent (3 min WBV, 3 min rest) for 20 minutes, twice weekly for 3 weeks. JPS, balance, and gait were evaluated before and after treatment. Results: Ankle JPS was improved after 3 weeks of WBV training (p=0.014). Participants in the WBV group showed greater improvements in speed (F1,21=5.221, p=0.035) and step width (F1,21=4.487, p=0.039) than participants in the conventional PT group. Conclusion: Three weeks of WBV training was effective in improving ankle JPS and gait variables in children with CP.

The purpose of this research report is to investigate the long-term effect of Adeli suit treatment (AST) in a child with cerebral palsy (CP) on spatial-temporal gait parameters, 10-meter walking speed, gross motor functional measure (GMFM) and performance on the pediatric balance scale (PBS). An eight-year-old girl with spastic diplegia classified as level III on the Gross Motor Function Classification System participated in this single-subject A-B design study, with a baseline and an intervention phase. The baseline phase was collected at one-week intervals for six weeks and then the AST intervention phase was carried out with 18 AST sessions, 50 min per session, once a week for an 18-week period. Spatial-temporal gait parameters significantly improved after the completion of 18 sessions. Furthermore, 10-meter walking speed, GMFM and PBS changed significantly from the baseline measurement (p < 0.05). In conclusion, the AST was effective in improving gait, gross motor function and balance in a child with diplegic CP. Clinically, neuro-rehabilitation with AST provided a complementary and alternative treatment for lower extremity rehabilitation in this child with CP. These findings provide preliminary evidence supporting the effectiveness of AST in children with spastic CP, and thus underscore the need for additional research in this area.
