Current diagnostic methods, such as lateral foot radiography and physical examination, primarily assess simple static foot conditions. The Footscan test can be employed to evaluate the static and dynamic balance of patients with flatfoot; however, the precise reference value for various Footscan test results remains undetermined.ObjectiveThis study aimed to contribute to the body of knowledge regarding flatfoot diagnosis by identifying objective differences between patients with and without flatfoot.MethodsThis study focused on individuals aged 19-50 years without ankle injuries or surgeries that could affect balance. The Footscan system was used to evaluate static balance using the total travel distance (TD) of the center of pressure in the standing position for 10 s. For dynamic balance indices, the sole was divided into forefoot, midfoot, and hindfoot zones by the system, and the contact distribution of each zone was quantified as a percentage during a 1-min walking period. Statistical analysis was performed to compare the normal and flatfoot groups, leading to the determination of cutoff values for clinically significant indices.ResultsThe study included 116 feet of 58 healthy individuals and 56 feet of 28 patients with flatfoot. Significant differences were found between the two groups for all static and dynamic balance variables. Logistic regression analysis identified TD (<i>p </i>= 0.001) and midfoot contact distribution (<i>p </i>< 0.001) as significant risk factors of flatfoot. Receiver operating characteristic analysis determined the cut-off values with the highest sum of sensitivity and specificity for diagnosis: TD ≥ 20.5 mm and midfoot contact distribution ≥ 18.95%.ConclusionsThe Footscan test indices showed significant differences in static and dynamic balance between patients with flatfoot and normal individuals.

The inclusion criteria were a posture-related low back soreness and discomfort for at least 2-3 weeks with a pain intensity of greater than or equal to 5 on numerical rating scale. The primary outcome measure was a pain intensity difference from baseline to day 7 and day 15. Secondary outcome measures were a categorical pain relief scale and Oswestry disability index (ODI).ResultsThere was a significant decrease in the pain intensity (p < 0.001) compared to placebo at the end of 15 days of study in the Rhuleave-K group. After 7 days of supplementation of Rhuleave-K, there was a 56% reduction in pain intensity and by the end of the study, there was 98.5% reduction.

Each participant underwent two interventions: dynamic taping and no taping.
