Effects of Vestibular Exercises and Motor Control in Cervicogenic Dizziness

Study Overview
=================
Brief Summary
-----------------
The feelings of imbalance, unsteadiness, and disorientation with cervicogenic dizziness is not clear. It has been suggested that a disruption of the normal afferent signals from the upper cervical proprioceptors to the vestibular nucleus results in an inaccurate depiction of head and neck orientation in space due to highly developed proprioceptive system that allows the neuromuscular control of cervical spine and effective use of vital organs in the head through unique connections to the vestibular and visual systems. Motor Control Therapeutic Exercises and vestibular exercises have been used to increase motor control and reduce pain and disability in patients with neck pain.

Detailed Description
-----------------
Cervicogenic dizziness is defined as a sensation of instability or disequilibrium that occurs with the pain and stiffness in cervical spine and is aggravated by neck movements or positions. Dizziness is a common indication in people with cervical spine dysfunction. cervicogenic dizziness as a nonspecific sensation of altered orientation in space and disequilibrium originating from abnormal afferent activity from the neck which is thought to be caused by disorders in the upper cervical spine and commonly it is associated with cervical stiffness neck pain or headache. Motor control can also be defined as the capacity of how the central nervous system produces of useful movements that are coordinated and integrated with the rest of the body and the environment. Thus, motor control therapeutic exercises (MCTE) are used to improve the conditions of patients. Motor Control Therapeutic Exercises have been used to increase motor control and reduce pain and disability in patients with neck pain. MCTE comprised of cranio-cervical flexor exercise, cranio-cervical extensor exercise, co-contraction of flexors and extensors, a synergy exercise for retraining the strength of the deep neck flexors. Schenk et al. have published case studies in which they describe the diagnosis, treatment, and outcomes of a patient with cervicogenic dizziness co-managed by a vestibular and an orthopedic manual physical therapist. They argue that manual therapy combined with vestibular rehabilitation may be superior in the treatment of cervicogenic dizziness. Literature states that vestibular exercises have been used to increase motor control and reduce pain and disability in patients with neck pain.

| Experimental: Motor Control Group<br>This group will receive treatment which comprises of therapeutic exercises, During the first 4 weeks, motor control and ROM exercises will be prescribed in order to improve muscular endurance of deep flexors muscles and to improve the ROM of cervical spine in flexion, extension, rotation and side bending and lateral rotation in. These exercises will be performed at a rate of 3 sets and an intensity of 15 repetitions per day | Other: Motor Control Group<br>* will received treatment which comprises of therapeutic exercises, During the first 4 weeks, motor control and ROM exercises will be prescribed in order to improve muscular endurance of deep flexors muscles and to improve the ROM of cervical spine in flexion, extension, rotation and side bending and lateral rotation in.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Dizziness Handicap Inventory Scale | The purpose of this scale is to identify difficulties that you may be experiencing because of your dizziness. It has three subscales namely physical, emotional and functional. The total maximum score is 100 and minimum is 0. | Change from Baseline ,dizziness to 4Weeks, 8 weeks | 
| Neck Disability Index (NDI) | This questionnaire has been designed to give us information as to how your neck pain has affected your ability to manage in everyday life. Is 10 item scale each item assesses different neck pain complaints. The total maximum score is 50 and minimum is 0 | Change from Baseline , to 4Weeks, 8 weeks | 
| Berg Balance Scale | Berg Balance Scale is a 14 items scale, to assess static and dynamic balance. Scoring of this scale is done on a 5 point scale where 0 is inability to perform a task and 4 shows the independent task performance. The maximum score of this scale is 56 showing excellent performance | Change from Baseline , balance and fall prevention to 4Weeks, 8 weeks |
