This research aims to determine whether there is a difference in posture stability and leg muscle activity as a result of the visual partial blocking of NVP(No Visual Pattern), VVP(Vertical Visual Pattern), HVP(Horizontal Visual Pattern), and DVP(Diagonal Visual Pattern) when partial blocking is applied using goggles in a preposition.
Physically and mentally healthy adults in their 20s and 30s were selected as the subjects of this study, and 31 people, who agreed to participate in the study after hearing sufficient explanations about the purpose of this study, were assigned and conducted.
The research method measured the muscle activity of the gastrocnemius lateral, medial and tibialis anterior muscles, while measuring posture stability under four conditions using NVP, VVP, HVP, and DVP on a Biodex balancing system machine. Repeated measurement variance analysis was used for statistical analysis, and the following results were obtained.
There was no statistically significant difference when applied with NVP, VVP, HVP, and DVP in the gastrocnemius lateral muscle based on the visual partial blocking conditions(p>.05).
There was no statistically significant difference when applied with NVP, VVP, HVP, and DVP in the gastrocnemius medial muscle based on the visual partial blocking conditions(p>.05).
There was no statistically significant difference when applied with NVP, VVP, HVP, and DVP in the tibialis anterior muscle based on the visual partial blocking conditions(p>.05).
There was no statistically significant difference when applied with NVP, VVP, HVP, and DVP in the overall stability index of postural stability based on the visual partial blocking conditions(p>.05).
There was a statistically significant difference when applied with NVP, VVP, HVP, and DVP in the anterior and posterior stability index of postural stability based on the visual partial blocking conditions(p<.05).
There was no statistically significant difference when applied with NVP, VVP, HVP, and DVP in the internal and external stability index of postural stability based on the visual partial blocking conditions(p>.05).
The above results showed that when VVP, HVP, and DVP were used based on visual blocking, there was no significant difference in the tibialis anterior and gastrocnemius muscle, which are muscles used mainly in ankle joint strategy, but the anterior and posterior stability index of postural stability, particularly when applied as VVP, was the most significantly lowered. This appears to be the most blocked when the visual blocking with VVP is compared to that of HVP, DVP, and improve stability, and balancing training using goggles applied with VVP would be possible. Furthermore, it can be used as a reference for improving the balance and the posture control of patients with reduced balance ability or visual diseases, as well as an intervention in rehabilitation to restore the patient's balance function. Future research on blocking, balancing, and maintaining posture, and various visual interventions is required.
