Dermatomes Upper Limb Peripheral Neurological Examination Images Dermatomes and myotomes of the upper limb. for more information on examining the upper limb, see the geeky medics osce guide to neurological examination of the upper limb. peripheral nerve injuries. the nerve supply to the upper limb is commonly damaged by fractures, penetrating trauma and external compression. patients with neurological signs. Testing of dermatomes is part of the neurological examination. they are primarily used to determine whether the sensory loss on a limb corresponds to a single spinal segment, implying the lesion is of that nerve root (i.e., radiculopathy ), and to assign the neurologic “level” to a spinal cord lesion [9] . To test vibration sense, the examiner places a finger under the patient’s distal interphalangeal joint and presses a lightly tapped 128 cycle tuning fork on top of the joint. the patient should note the end of vibration about the same time as the examiner, who feels it through the patient’s joint. It is important that clinicians have a sequence of their choosing that they use consistently. components of the standard neurologic examination are found in table 1 and discussed in detail in this review ( table 1 ). the text is adapted, with permission, from reference 1 [ 1 ]. the examination of comatose patients is discussed separately.
