The Effect Of Cervical Muscle Fatigue in Neck Proprioception and Postural Stability
The Effect of Cervical Muscle Fatigue on Neck Proprioception and Postural Stability
PURPOSE:
To investigate the effect of cervical muscle Fatigue on neck proprioception and postural stability during cervical flexion.
BACKGROUND:
Postural stability is the ability to maintain the body in equilibrium either at rest or in a steady state of motion . Muscle fatigue is the diminished response of muscle to repeated stimulus. Cervical proprioceptive inputs provide important somatosensory information influencing postural stability. Hence, the investigators performed this study to evaluate the effect of experimentally induced fatigue on general cervical musculature on postural stability .
HYPOTHESES:
This study will hypnotize that:
- Cervical flexor muscle fatigue will have a significant effect on neck proprioception
- Cervical muscle fatigue will have a significant effect on posture stability
RESEARCH QUESTION:
Will fatigue of cervical flexors have an effect on neck proprioception and postural stability?
Study Overview
Detailed Description
the research methodology that will be used
Induction of fatigue using isometric neck flexor muscle endurance test (NET):
An isometric neck muscle endurance test (NME test) will be performed for the deep neck flexors (Rectus Capitus Anterior, Rectus Capitus Lateralis, Longus Capitus, Longus Colli) until exhaustion in all participants occurs. With the subject in hook lying position through CHIN RETRACTION AND HEAD ELEVATED FROM THE COUCH.
All the assessment measurements will be done before and just immediately after performing the cervical muscle fatigue then after 15 minutes of fatigue induction(fatigue recovery) A. Measurement of neck proprioception using cervical joint position error test via OVERHEAD LASER POINTER
B. Measurement of postural stability using :
- Biodex balance system(limit of stability) to measure postural stability
- Multi-Directional Reach Test

Multi-Directional Reach Test
Time Frame: six months
|
Multi-Directional Reach (MDRT) is an inexpensive screening tool to determine the limits of stability of individuals in 4 directions.
It measure how far an individual can voluntarily reach, thereby shifting the COG to the limits of the BOS with the feet stationary.
The MDRT is a valid and reliable clinical measure for limits of stability.
The test can be used to assess human postural stability in different four direction as follow (Roberta 2001)

Biodex Balance System for The postural stability test
Time Frame: six months
|
The postural stability test emphasized on subject's ability to maintain center of balance.
The subject's score on this test will assess the deviations from center, thus a lower score is more desirable than a higher score.
Platform stability could be varied during this test by selecting (more options) from the Postural Stability Testing screen.
It was proved that trial time, number of trials, starting and ending platform stability, rest count-downs or bilateral test could be set (Tropp and Odenrick., 2011).
