Overview

In this study, the investigators aimed to investigate the relationship between the dynamic valgus index and the dynamic valgus index during the landing phase of the single leg squat movement of sedentary people according to gender and to evaluate the effect of the postural alignment of the ankle and foot complex on the stability of the knee joint during the single leg squat.

Single leg squatting is the basis of many functional activities such as walking, running, landing and balance. Single leg squat is generally preferred for lower extremity rehabilitation and assessment of dynamic hip joint control, lower extremity kinematics and lower extremity alignment. Many studies have used single leg squats for knee kinematics assessment. Excessive knee valgus, hip adduction and abduction of the knee joint during the single leg squat pose a risk of injury to the anterior cruciate ligament, medial collateral ligament and other ligaments. The single-leg squat test is frequently used clinically to provide a simple and convenient assessment of neuromuscular control for the lumbo-pelvic region. Misalignment of the lower limb can affect knee and hip kinematics during athletic movements, causing disorders such as anterior cruciate ligament lesions, iliotibial band syndrome and patellofemoral pain syndrome. The single leg squat test is a clinical functional test commonly used to assess clinical abnormal movement patterns of the lower limbs in terms of kinetic chain or coordinated muscle activity. This scale provides assessment of five dimensions: general impression, trunk posture, pelvis in space, hip joint movement and knee joint movement. Since the single-leg squat test tests both daily activity and lower limb balance ability during athletic tasks, it was deemed appropriate to perform it separately on both legs. It is a valid and reliable test preferred in the literature as a functional test that evaluates lower extremity and especially knee joint balance skills. In the light of this information, the aim of this study was to investigate the relationship between the dynamic valgus index and the dynamic valgus index during the landing phase of the single leg squat movement of sedentary people according to gender and to evaluate the effect of the postural alignment of the ankle and foot complex on the stability of the knee joint during the single leg squat.

Interventions

Sociodemographic profile, dynamic valgus index, single leg squat test, Q angle, Foot posture index, navicular drop test, pain assessment, muscle strength and flexibility testsBEHAVIORAL

During the single leg squat test, they will be asked to perform a squat every two seconds without bending forward or sideways while maintaining their balance with their hands crossed over their chest. While performing the movement three (3) times in a slow and controlled manner, they will be recorded with a video camera positioned at 90 degrees to their full height (approximately 3m). This recording will be evaluated in computer environment with Kineovea 0.9.5 motion analysis program and dynamic valgus index will be calculated. Q angle will be measured with a goniometer in both standing and supine position. Medial longitudinal arch height will be measured by navicular drop test. Foot posture of the participants will be evaluated with the Foot Posture Index developed by Redmond et al. (2006) to evaluate foot posture.

Outcomes

Primary Outcomes

Dynamic Valgus Index(DVI)

The mark between the participant's SIAS and the midpoint of the patella will be marked as the femur segment, and the mark between the patella and the foot will be marked as the tibia segment and video recording will be taken. Dynamic Valgus Index Measurement will be performed using Kineovea 0.9.5 motion analysis program. Knee frontal plane projection angle(KFPPA) will be measured with the computer program. The angle hip frontal plane projection angle(HFPPA) will be measured between the pelvis and the femur segment by determining the pelvis segment with the line connecting both SIAS marks. HFPPA will be subtracted from 90 degrees (90º - A) and KFPPA will be subtracted from 180 degrees (180º - B) and the DVI angle will be obtained by summing these two values.

Time frame: 3 months

Single leg squat test

The participants' spina iliaca anterior superior (SIAS) in the frontal plane, the middle of the patella on both sides, and the middle of the ankle will be marked by sticking red colored tape. The test protocol will be explained, visually demonstrated, and three (3) repetitions will be made to try and get used to the test. A T-shape will be drawn on the floor with tape to facilitate the evaluation and they will be asked to hold their free foot behind their back while standing barefoot. They will be asked to perform a squat every two seconds without leaning forward and sideways, while maintaining their balance with their hands crossed on their chest. While performing the movement three (3) times in a slow and controlled manner, they will be recorded with a video camera positioned at 90 degrees to their full height (approximately 3m). It will be observed on the video whether the participants are positioned in the straight midline towards the single leg squat test line. If the patella

Foot posture index

The participants' foot posture will be assessed using the Foot Posture Index developed by Redmond et al. (2006) to assess foot posture. It is mainly used to define the degree of supination, neutral or pronation position of the foot. All assessments are performed in a comfortable standing position with equal weight on both feet. This posture is reported to be close to the positions taken by the foot during the gait cycle. This index is composed of 6 assessment headings: palpation of the talus head, inclination above and below the lateral malleolus, calcaneal inversion/eversion assessment in the hindfoot, talonavicular alignment (concavity/convexity), medial arch height and forefoot abduction/adduction in the forefoot.
