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

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

    Abstract : 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. READ MORE

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

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

    Abstract : 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. READ MORE

  5. 3. Human periodontal mechanoreceptors : functional properties and role in jaw motor control

    Author : Skjalg E Johnsen; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Periodontal mechanoreceptors signal information about tooth loads to the central nervous system and are considered to be important for the control of oral motor behaviors, like biting and chewing. Surprisingly, very little is known about the functional properties of periodontal mechanoreceptors at posterior teeth. READ MORE

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

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

    Abstract : 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. READ MORE

  7. 5. Wrist ligaments : innervation patterns and ligamento-muscular reflexes

    Author : Elisabet Hagert; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Wrist ligaments; mechanoreceptors; proprioception; sensorimotor functions; neuromuscular control; ligamento-muscular reflexes; immunohistochemistry;

    Abstract : Objectives: The principal role of wrist stability is to facilitate the dexterous hand in a multitude of functions. To achieve joint stability, in general, a fine interaction of both static and dynamic elements is of essence. READ MORE
