Influence of a smartphone use on dynamic balance in healthy adolescents

Abstract

Purpose. The aim of the study was to detect the immediate and late effects of using a smartphone for 30 consecutive minutes on dynamic balance in healthy adolescents. Methods. Overall, 96 healthy adolescents of both genders, aged 15-18 years, were randomly assigned to the study and the control group. The subjects in the study group used a smartphone for 30 consecutive minutes; smartphones were not allowed in the control group. A Biodex system was used to assess the dynamic balance initially, as well as immediately after and 1 hour after the intervention. Results. MANOVA test revealed that there were statistically significant differences in the overall stability index and anteroposterior stability index (p = 0.002 and 0.04, respectively), with a statistically insignificant difference in the mediolateral stability index (p = 0.46) within the study group. Significant differences were observed in the immediate measurements of both overall stability index and anteroposterior stability index (p = 0.0001 and 0.03, respectively), while statistically insignificant differences were noted in the measurements of mediolateral stability index between the groups. Conclusions. The dynamic balance decreased after 30 consecutive minutes of smartphone use, so care should be taken to avoid accidents while walking or performing other daily activities. This effect, however, disappeared 1 hour later.

Impact of smartphone use on posture control in healthy adolescents

“…Prolonged muscular tension alters the sensitivity of neck proprioception, affecting balance and resulting in postural instability [18]. This study's findings align with the findings of Shafeek et al [19], who investigated the impact of SP usage on dynamic balance in healthy adolescents, and their work revealed Md -mean difference, * significant values a significant immediate influence of SP use on balance. Moreover, our findings are comparable to those of Lee et al [20], who found that using an SP changes the degree to which healthy adults can control their posture.…”

Maze Control Training on Kinesthetic Awareness in Patients with Stroke: A Randomized Controlled Trial

“…Previous review studies reported limited evidence for some interventions for stroke patients including repetitive task training, exercise therapy, care-mediated exercise, physical fitness training, use of unstable support surfaces, and virtual therapy that may be effective in balance recovery after stroke. For confirming this finding, further research is recommended [ 8 , 35 ].…”

“…Research reports damage to such sensory system with stroke patients with a high rate of proprioception affection, which affects both static and dynamic postural stability. Therefore, evaluation by the clinical test of sensory interaction and balance (CTSIB) should be considered for both aspects of static and dynamic postural control by the ability to control the tilting angle of the Biodex platform [ 8 ].…”
