[Estimation of motor ranges and muscle strength in cervical spine after total laryngectomy].

After total laryngectomy and after complementary treatment (radiotherapy) there are many functional disorders in the range of head and neck. It was observed, that muscles of this area became weakened with simultaneous increase of their rest tension. These changes affect reduction of physiological motor range of the cervical spine. Comparison of function of cervical muscle between patients after total laryngectomy and healthy people allows to characterize defects of neck movements. Detailed estimation of muscle strength and move range in cervical spine after total laryngectomy will enable application of effective physiotherapy program.
