Brief summary

The aim of the study is, to evaluate and classificate the medial longitudinal arch height in adult individuals. Aged between 18-40 years,350 adults who are voluntarily participate is going to be evaluate with Feiss Line(FL), Navicular Drop(ND) and Longitudinal Arch Angle(LAA) in subtalar neutral and resting position. Maximum, minimum values are going to be calculated. The 95% and 68% prediction intervals will be used as cut off limits.

Detailed description

The aim of the study is, to evaluate and classificate the medial longitudinal arch height in adult individuals. Aged between 18-40 years,350 adults who are voluntarily participate is going to be evaluate with Feiss Line(FL), Navicular Height(NH) and Longitudinal Arch Angle(LAA) in subtalar neutral and resting position. Maximum, minimum values are going to be calculated. Participant's height, weight and foot length, from posterior aspect of calcaneus to the longest toe's tip, will be measured. Center of the medial malleolus, the navicular tuberosity and the head of the first metatarsal bone will be marked with a CD marker. With these landmarks in foot's relaxed position, neutrally, FL, NH and LAA will be measured by a ruler. Feiss Line is a drawn line between the center of the medial malleolus to the head of the first metatarsal bone and then perpendicular line distance between this line and the navicular tuberosity will be drawn.The vertical line between the ground and the tubercle indicates Navicular Height. Center of goniometer placed at the navicular tuberosity then goniometer arms follow the medial malleolus and the head of the first metatarsal bone, degree between two arms indicates Longitudinal Arch Angle. FL, NH, LAA mean values will be calculated. The 95% and 68% prediction intervals will be used as cut off limits.

Design outcomes

Primary

MeasureTime frameDescription
Medial longitudinal arch height10 daysNavicular Height(NH) mean value, Center of the medial malleolus, the navicular tuberosity and the head of the first metatarsal bone will be marked with a CD marker. With these landmarks in foot's relaxed position, neutrally NH will be measured by a ruler. The vertical line between the ground and the tubercle indicates Navicular Height. After all data collection, the data will be entered into the Statistical Package for the Social Sciences (SPSS) and the average value calculated.

Secondary

MeasureTime frameDescription
Mean value differences between male and female10 daysMean value differences between male and female will be compared statistically with the Statistical Package for the Social Sciences (SPSS) program.
Correlation of arc measurements and standing length10 daysCorrelation of arc measurements and standing length will be correlated statistically with the Statistical Package for the Social Sciences (SPSS) program.
Medial Longitudinal Arch Cut Off Values10 daysAfter average values calculated, cut off values will be generated from the data obtained from the arch height in standard, healthy individuals.
