Somatosensory deficits
2018, Handbook of Clinical NeurologyCitation Excerpt :However, it is difficult to conclude whether some sensory deficits are caused by the motor deficit itself or by a loss of some somatosensory tracts. Animal experiments have demonstrated that somatosensory information and the anatomic connection between the motor and the somatosensory cortex are important for the acquisition of new motor skills (Bornschlegl and Asanuma, 1987; Nudo et al., 2000). Other data suggest that motor impairments after pure motor stroke are at least partly due to a loss of sensory information caused by sensorimotor disconnection (Nudo et al., 2000).
Effect of afferent input on motor cortex excitability during stroke recovery
2012, Clinical NeurophysiologyCitation Excerpt :Intracortical recordings in animals (Nudo and Milliken, 1996; Nudo et al., 1996) and functional imaging studies in humans have indicated that motor recovery is associated with reorganization of the motor (Calautti et al., 2001; Ward et al., 2003a,b) and somatosensory cortices (Roiha et al., 2011; Rossini et al., 1998, 2001). However, regaining of normal motor function demands not only recovery of the motor or somatosensory systems, but also a fluent integration of somatosensory afferent input with motor programs (Bornschlegl and Asanuma, 1987). Afferent somatosensory input has been proposed to mediate its effect on motor functions by modulating the excitability of the motor cortex (Asanuma and Arissian, 1984; Favorov et al., 1988; Liepert et al., 2004; Ridding and Rothwell, 1999; Tokimura et al., 2000).
Chapter 54 Imaging functional recovery from stroke
2008, Handbook of Clinical NeurologyCitation Excerpt :Studies that utilize techniques to enhance somatosensory input have shown effectiveness at improving motor function in healthy (Muellbacher et al., 2002) and paretic limbs (Floel et al., 2004). Sensorimotor integration theory might provide insight into the basis for these motor gains: motor output is inextricably linked to sensory input, and those unable to voluntarily complete movements cannot produce appropriate sensory patterns associated with motor effort (Bornschlegl and Asanuma, 1987; Pavlides et al., 1993). This theory provides a rationale for active assistive therapy (Reinkensmeyer et al., 2004).
Reorganisation of the somatosensory system after early brain damage
2007, Clinical NeurophysiologyCitation Excerpt :In other words, motor and sensory function seem to be reciprocally related when they are represented in the same cerebral hemisphere, while they are partially or totally unrelated if inter-hemispheric dissociation occurs. This finding may be supported by intra-hemispheric interconnections between primary sensory and motor cortex, which are considered crucial for the quality of motor performance and for the degree of recovery following focal lesions (Asanuma and Arissian, 1984; Bornschlegl and Asanuma, 1987; Pantano et al., 1995). This hypothesis is supported by the observation of severe metabolic depression in the thalamus ipsilateral to the affected hemisphere in patients with poor or no improvement of hand motor control following stroke (Binkofski et al., 1996; Fries et al., 1993).
Imaging Motor Recovery After Stroke
2006, NeuroRxCitation Excerpt :Similar results have been observed with intensive neuromuscular stimulation of the affected hand, with an increase in cortical activation in the ipsilateral somatosensory cortex.111 The sensorimotor integration theory might provide insight into the basis for these motor gains; motor output is inextricably linked to sensory input and movements cannot be properly produced without appropriate sensory input patterns.137,138 This theory provides a rationale for active assistive therapy.139
