About this study
Official title: The Relationship Between Sensory Impairments and Upper Extremity Motor Functions in Children With Unilateral Cerebral Palsy
Cerebral palsy (CP) is characterized by many problems related to brain damage. One of these is sensory impairment. Sensory impairments in CP patients can also occur together with motor functions. Detecting sensory impairments (two-point discrimination, vibration, joint position sense, thermal sensation, stereognosis, graphesthesia) in the arm, forearm, and hand (upper extremity) in CP patients and investigating their relationship with motor functions is important. The aim of this research is to investigate the relationship between upper extremity sensory impairments and motor functions in patients diagnosed with unilateral (affecting one half of the body) CP.
Read the detailed description
The aim of this study is to investigate the relationship between sensory impairments and upper extremity motor functions in patients with unilateral cerebral palsy (CP). It will be planned as a cross-sectional study. The study will include 55 unilateral CP patients and 55 healthy volunteers. Sensory functions evaluated include two-point discrimination, joint position sense, vibration sense, thermal sense, stereognosis, and graphesthesia. Motor functions will be assessed using the Gross Motor Functional Classification System (GMFSS), Hand Skills Classification System (ESCS), Abilhand-Kids scale, Box and Block test, and Nine Hole Peg test. The relationship between sensory parameters and motor functions will be investigated.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
| Study group | Role | What they receive |
|---|---|---|
| Patient Group | Children aged 6-15 with unilateral (hemiplegic) cerebral palsy | |
| Healthy Group | Healthy children aged 6-15 |
What is being measured
The primary outcome is the main question the study is designed to answer.
Sensory Function:Two-point discrimination
Two-point discrimination is defined as the ability to distinguish between two simultaneous points of touch, which is most acute in areas of the skin with a high density of touch receptors, such as the fingers and face. The test will be performed using a discriminator device called an esthesiometer.
Measured: Single assessment at baseline (cross-sectional evaluation)
Sensory Function:Joint position sense
Joint position sense is the ability to detect body segment position in space and is commonly used to represent proprioceptive performance.
Measured: Single assessment at baseline (cross-sectional evaluation)
Sensory Function:Vibration
Assessment of vibration sense is the best clinical test of the dorsal column pathway. A low-frequency (128 Hz) tuning fork is applied to bony prominences and the patient (with closed eyes) is asked to report when the vibration starts and stops.
Measured: Single assessment at baseline (cross-sectional evaluation)
Sensory Function:thermal sense
The volunteer's upper extremity is successively touched with tubes filled with hot and cold water, and the volunteer is asked to respond as hot or cold. Thermal sensation is recorded as 'preserved', 'impaired', or 'unable to assess'.
Measured: Single assessment at baseline (cross-sectional evaluation)
Sensory Function:Stereognosis
Without visual or auditory cues, objects are placed in a sequence, and the child is asked to grasp them and identify the name of the object. Each object is awarded '1' point for being correctly identified, and '0' points for not identifying it. Scores ranging from 0 to 6 are recorded.
Measured: Single assessment at baseline (cross-sectional evaluation)
Sensory Function:Graphesthesia
Six different drawings-letters, numbers, circles, and vertical lines-are made on the palm of the volunteer's hand using a blunt pencil, without any visual or auditory stimuli. Each correct drawing earns '1' point, and each incorrect drawing earns '0' points. Scores ranging from 0 to 6 are recorded.
Measured: Single assessment at baseline (cross-sectional evaluation)
Motor Function: Gross Motor Functional Classification System
This classification system consists of 5 levels.
Measured: Single assessment at baseline (cross-sectional evaluation)
Motor Function: Hand Skills Classification System
This classification system consists of 5 levels.
Measured: Single assessment at baseline (cross-sectional evaluation)
Motor Function: Abilhand-Kids Scale
Twenty-one daily activities were evaluated. Participants were asked to rate an activity-which the child attempted to perform independently using both upper extremities-on a scale of 0-42 points.
Measured: Single assessment at baseline (cross-sectional evaluation)
Motor Function: Nine Hole Peg Test
The Nine Hole Peg Test was developed to measure finger dexterity, also known as fine manual dexterity. The test consists of a wooden board with nine holes and nine small sticks designed to be inserted into those holes. The participant is asked to take the sticks from the box one by one with the hand being tested and insert them into the holes as quickly as possible; then, they must remove the sticks one by one and return them to the box.
Measured: Single assessment at baseline (cross-sectional evaluation)
Motor Function: Box and Block Test
The Box and Block Test (BBT) measures unilateral gross manual dexterity. Participants are given 60 seconds to move wooden blocks by hand to the opposite compartment as quickly as possible. At the end of 60 seconds, the number of wooden blocks transferred to the opposite compartment is noted.
Measured: Single assessment at baseline (cross-sectional evaluation)
