  1. 1. Vibration exposure of the glabrous skin of the human hand

    Författare :Ronnie Lundström; Ludwik Liszka; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Vibration; hand; skin; mechanical impedance; mechanoreceptors; tactile perception; high-frequency;

    Sammanfattning : An occupational exposure to hand-arm vibration can cause a complex of neurological, vascular and musculo-skeletal disturbances, known as the 'vibration syndrome'. However, the underlying pathophysiological mechanisms are not at all clear. LÄS MER

  3. 2. To grip and not to slip : sensorimotor mechanisms in reactive control of grasp stability

    Författare :Charlotte Häger Ross; Roland S. Johansson; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; human; hand; precision grip; grasp force; friction; cutaneous mechanoreceptors; sensorimotor integration; motor control;

    Sammanfattning : The reactive control of fingertip forces maintaining grasp stability was examined in man during a prehensile task. Blindfolded subjects used the precision grip between the tips of index finger and thumb to restrain an object that was subjected to unpredictable load forces. These were delivered tangential to the parallel grip surfaces of the object. LÄS MER

  4. 3. Observations on morphology and function of cutaneous and subcutaneous sensory mechanoreceptors : an experimental study in mammals

    Författare :Birgit Stark; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :mechanoreceptors; somatosensory organisation; blood-nerve barrier; Glucose transporter-1; nerve regeneration; TGF-ß family; neurotrophin receptors;

    Sammanfattning : Tactile sensory discrimination is dependent upon an intact system of peripheral mechanoreceptors, their nerve fibre afferents with cell bodies in the dorsal root ganglion and the dorsal column-medial lemniscal system which relays tactile information from the skin to the cortex. Injury to any part of the afferent pathways leads to compromised mechanoreceptive perception. LÄS MER

  5. 4. Analysis of Adaptation in Human Postural Control

    Författare :Per-Anders Fransson; Lund näs- och halssjukdomar Öron-; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Physical medicine; kinesitherapy; revalidation; rehabilitation; Rehabilitering medicinsk och social ; Adaptation; Postural control; Proprioception; Vestibular; Posturography; neuropsykologi; Neurologi; neurophysiology; neuropsychology; Neurology; hörsel- och talorganen; audiologi; Otorinolaryngologi; auditive system and speech; audiology; Otorhinolaryngology; Movement pattern; Sensorimotor integration; Muscle fatigue; Age; Cutaneous sensation; neurofysiologi;

    Sammanfattning : The ability to obtain correct balance control information and adjust motor performance appropriately are essential elements in effective postural control. However, functional disorders may affect the reliability of receptor information and ability to carry out corrective motions needed to maintain balance. LÄS MER

  7. 5. New functional and anatomical aspects of the organisation of human peripheral nerve

    Författare :Rolf Ekedahl; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Somatosensory system; Peripheral nerve organisation; somatotopy; modalitysegregation; cutaneous mechanoreceptors; Human.Huddinge 1996;

    Sammanfattning : The functional topography of peripheral nerves has been studied by various indirect electrophysiological and histological methods. Even though some studies have suggested the presence of a somatotopical arrangement of nerve fibres, the prevailing view is that a random distribution of nerve fibres develops in the nerve due to the repeated rearrangement of nerve fascicles along their centripetal course.
