After the botulinum toxin-A injection, the patients will be included in the comprehensive physiotherapy program thrice a week for a total of 12 weeks. The physiotherapy program will be consisted of the ankle range of motion and stretching, strengthening of the antagonist muscles, proprioception exercises, functional walking training and static and dynamic balance training.

Light touch pressure (tactile) sensation will be assessed by using Semmes-Weinstein Monofilaments kit (Baseline, White Plains, New York, NY,USA) at the first and fifth metatarsal heads and heel of the plantar side of each foot. The light touch pressure threshold will be defined as the thinner monofilament value the participant correctly identified twice out of three trials for each application site. Higher scores mean worse tactile sensation.

Muscle tone and spasticity will be measured with MAS. Muscle tone is scored between 0-4. Higher scores mean more severe spasticity.

Within the Modified Tardieu Scale (MTS), angle of arrest of the ankle joint at slow speed (XV1), angle of catch at fast speed (XV3), spasticity grade (Y), and spasticity angle (X) will be recorded. Angles of arrest and catch will be measured by a goniometer and angle of arrest of the ankle joint at slow speed was recorded as passive range of motion. Higher X angle points out dynamic component of spasticity. Higher Y scores mean more severe spasticity.

The Sit to stand (STS) test will be done by Balance Master device. Weight transfer time (sec), rising index (%) and sway velocity (deg/sec) will be recorded. The STS is a performance test quantifying the patient's ability, on command, to quickly rise from a seated to a standing position. The STS quantifies time required to transfer weight from the buttock to the feet (weight transfer time (sec)), the strength of the rise (rising index (%)), and the center of gravity sway velocity (deg/sec) during the rise to stand and the first five seconds during standing. Higher scores mean worse dynamic postural control.

The Step&Quick Turn (SQT) test will be done by Balance Master device. The SQT is a performance test that quantifies turn performance characteristics. The patient is instructed to take two forward steps on command, and then quickly turn 180˚ to either the left or right and return to the starting point. The time required to execute the turn (sec), and the velocity of COG sway (deg) during the turn will be recorded. Higher scores mean worse dynamic postural control.

Two-point discrimination will be assessed by using a discriminator (Baseline®, White Plains, New York, NY, USA) on the forefoot and heel of the plantar side of each foot, and scored as the minimum distance in mm between two stimulus points, which were correctly identified as distinct points twice out of three trials for each site. Higher scores mean worse two-point discrimination.

The lower extremity selective voluntary motor control will be assessed with SCALE tool. Hip, knee, ankle, subtalar, and toe joints are assessed bilaterally in SCALE. Selective voluntary motor control is graded at each joint as 'normal' (2 points), 'impaired' (1 point), or 'unable' (0 points). The SCALE score is the sum of each joint scores and assumes a 10 point maximum per limb. The total SCALE score is between 0-20 and higher scores mean better selective motor control.

Functional mobility and balance will be assessed the TUG test. It records the time a child needs to stand up from a chair with foot contact, to walk three meter to a target, turn around and return to the chair and sit down as quickly and safely as possible. The test will be repeated three times and the average time (sec) will be recorded. Higher scores mean worse functional mobility.
