Introduction: The aim of this work was to evaluate the effect of post-isometric relaxation on muscle tone in patients with cervical vertigo. Material and methods: The study was conducted on a group of 100 patients including 65 women aged 20–76 years and 35 men aged 20–73 years, treated at the Department of Otolaryngology and Laryngological Oncology, Medical University Teaching Hospital in Lodz. The patients were randomized into 2 groups: I – 50 patients with cervical vertigo, II – control group of 50 healthy people without vertigo. Each patient underwent a detailed interview, subjective, otolaryngological, otoneurological and physical interviews, and routine laboratory tests. Neurology, ophthalmology and internal medicine specialists were consulted for each case. The patients underwent Doppler ultrasound study of cranial vessels, computed tomography of cervical spine and head. Each patient had an individually selected set of exercises taking into account his/her disease and possible contraindications. Exercises included post-isometric relaxation of paravertebral muscles of cervical spine during 2 months. Objective analysis of therapy outcome was performed (before, after 2 weeks, after 1 month and after 2 months) based on linear measurement of active range of motion (ROM) in the cervical spine, muscle strength (Lovett’s scale) and severity of vertigo (Silvoniemi’s criteria). Results: The study showed a significant improvement of range of cervical spine motion and muscle strength as a result of exercises performed. Conclusions: Most patients (82.3%) obtained complete resolution or significant reduction of severity of cervical vertigo both in the objective tests (active ROM of cervical spine and muscle strength) and in subjective reports (Silvoniemi’s criteria).
