Foot Positions Affect Basketball Players With Flatfoot

Beni-Suef University84 enrolled

Overview

This study investigated the effect of various initial foot positions on knee and ankle proprioception, balance, dynamic balance, vertical jump, and electromyographical muscle activity in basketball players with FF.

Objective: To investigate the effect of various initial foot positions on knee and ankle proprioception, balance, dynamic balance, vertical jump, and electromyographical muscle activity in basketball players with FF. Methods: Eighty-four basketball players with chronic ankle instability were distributed to three groups (28 with flexible FF, 28 with rigid FF, and 28 without FF). The outcome measures will include static and dynamic balance, knee and ankle proprioception, vertical jump, and electromyography (EMG) of ankle muscles (including gastrocnemius (GE), soleus (SOL), tibialis anterior (TA), and peroneus longus (PL) muscles)

Outcomes

Primary Outcomes

Knee proprioception with repositioning error test

The knee proprioception will be measured using the repositioning error test on the dominant leg to measure the absolute angular error. This test will assess the ability of the participant to reproduce a previously performed position (45 and 15 degrees of knee flexion).

Time frame: 3 months

Ankle proprioception with angular error measurement test

This test will assess the ability of the participant to reproduce previously performed ankle positions (15° dorsiflexion and 15° plantar flexion.)

Time frame: 3 months

Static balance with The Y-Balance test

The Y-Balance test will be used to evaluate static balance 27. The test will assess the ability of the participant to maintain balance while reaching as far as possible in all three directions (anterior (A), posteromedial (PM), and posterolateral (PL) directions).

Time frame: 3 months

Dynamic balance with Biodex Balance device

In this study, dynamic balance will be measured by the Biodex Balance System (Biodex 945-302, Biodex Medical Systems Inc., New York, USA). The Biodex Balance System has been demonstrated to be a reliable and validated instrument to assess dynamic balance. The biodex will assess the anteroposterior and lateral stability.

Time frame: 3 months

Vertical jump height with vertical jump tester

A vertical jump tester (Sports Imports, Columbus, OH)32 will be utilized to evaluate the vertical jump height in cm of each participant. The achieved height distance in cm in each step will be recorded, and the maximum height will be used in the statistical analysis.

Time frame: 3 months

Electromyographical activity (EMG) during one-leg standing

A wireless surface EMG system will record electromyographical signals (EMG) of ankle muscles, including gastrocnemius (GE), soleus (SOL), tibialis anterior (TA), and peroneus longus (PL) muscles.
