Effects of Task-oriented Training in Patients With Peripheral Vestibular Hypofunction
Condition: Peripheral Vestibular Disorders
MeSH terms: Vestibular Diseases
Study type: Interventional

Summary: 
      The peripheral vestibular disorder is a heterogeneous disorder that occurs due to unilateral
      or bilateral involvement of the peripheral vestibular organs in the inner ear, characterized
      by dizziness, balance disorder, visual blurring with head movements, postural instability,
      and gait disturbance. In the treatment of vestibular disorders, medical and surgical
      approaches, as well as vestibular rehabilitation are included. Vestibular rehabilitation
      should aim at repetitive stimulation of the vestibular sensory organs and improving
      peripheral sensory inputs by providing strong synaptic plasticity between the hair cells in
      these organs and the damaged parts of the vestibular system. According to this information,
      task-oriented training based on the practice of the task in the real environment with plenty
      of repetition seems to be a suitable method for the requirements of the treatment of
      vestibular disorders. This study was planned to examine the effects of task-oriented training
      on balance and gait in patients with peripheral vestibular disorders.
    

Detailed description: 
      Patients with peripheral vestibular disorders refrain from moving because of the increase in
      dizziness and fear of falling. These patients prefer to stay still and limit themselves even
      in simple daily life activities such as vacuuming, cleaning the table, and walking. From this
      point of view, it is thought that using the tasks in daily life or the activities that form
      the basis of these tasks in treatment as in task-oriented training will reduce the activity
      limitations caused by vestibular disorders.

      In the recovery of the vestibular system, it is important to practice the functions that
      increase the symptoms with many repetitions. For example, symptoms that occur without head
      movement in the acute period after vestibular injury resolve rapidly, and disappear to a
      large extent as vestibular compensation develops. However, as the disease becomes chronic,
      losses occur in afferent inputs from the vestibular system and cause a negative effect on
      dynamic reflex functions. Therefore, vestibular rehabilitation should be aimed to stimulate
      the vestibular sensory organs repeatedly and to improve peripheral sensory inputs by
      providing strong synaptic plasticity between the hair cells in these organs and the damaged
      parts of the vestibular system. According to this information, task-oriented training based
      on the practice of the task in the real environment with plenty of repetition seems to be a
      suitable method for the requirements of the treatment of vestibular disorders.

      In addition, there is evidence that task-oriented training improves balance, mobility, and
      gait reduces the risk of falls, and improves the quality of life in neurological diseases
      such as Stroke, Multiple Sclerosis, and Parkinson's disease. This information supports the
      investigators' idea that task-oriented training may also be beneficial in improving balance
      and walking performance, which are the main symptoms of peripheral vestibular disorder.

      On the other hand, when the investigators examine the literature, there is no study examining
      the effects of task-oriented education in patients with peripheral vestibular disorders.

      The primary aim of this study is to examine the effects of task-oriented training on vertigo,
      dizziness, balance, gait and falls in patients with peripheral vestibular disorders. The
      secondary aim of the investigators' study is to examine the effects of task-oriented training
      on disability level and quality of life in patients with peripheral vestibular disorders.
    

Intervention name(s): Task-oriented training; Control group
Intervention type(s): Other; Other
Intervention description(s): Task-oriented training is defined as an approach based on movement science and motor learning, where the patient "makes functional movements specific to a certain task and receives feedback". Task-oriented training focuses on improving performance on functional tasks through targeted practice and repetition.; Gaze stabilization exercises included head-fixed right-left eye movements, head-fixed up-down eye movements, eye fixed right-left head movements, and eye fixed up-down head movements.
