A myotome (greek: myo=muscle, tome = a section, volume) is defined as a group of muscles which is innervated by single spinal nerve root. myotome testing is an essential part of neurological examination when suspecting radiculopathy. myotomes are much more complex to test then dermatomes, since each skeletal muscle is innervated by nerves derived from more than one spinal cord level.[1].
Lower Extremity Dermatomes And Myotomes Reflexes Grepmed The results showed that testing for paresis in myotomes had 22 40% sensitivity and 62 79 percent specificity which corresponds to a sensitivity of 31% and a specificity of 76%in the identification of the pathological disk level. the pooled positive likelihood ratios for all neurological examination components range between 1.02 and 1.26. Assess the knee jerk reflex (l3, l4) in each of the patient’s lower limbs. 1. remove the weight from the patient’s lower limb by either supporting it or asking the patient to hang their legs over the side of the bed. ensure the patient’s lower limb is completely relaxed before assessing the knee jerk reflex. 2. Specific tests. special tests. straight leg raise. compression of lower lumbar nerve roots (l4 s1) important to distinguish from hamstring tightness. considered positive if symptoms produced with leg raised to 40°. crossed straight leg raise. performing straight leg raise in uninvolved leg produces symptoms in involved leg. Myotomes are part of the somatic (voluntary) nervous system, which is part of your peripheral nervous system. the peripheral and central nervous systems communicate with one another. the motor nerve roots are responsible for muscle movement. they branch out from the different parts of the spinal cord. a myotome is the group of muscles on one.
