“…However, therapeutically, this approach runs counter to practice in sensorimotor stroke, where it has been shown that early injury responses heighten neuroplastic potential (12)(13)(14)(15)(16)(17)(18)(19).…”

One Sentence Summary: The first 3 months after an occipital stroke are characterized by a gradual -not sudden -loss of visual perceptual abilities and increased rehabilitative potential if visual discrimination training is administered in the blind field. Abstract:Stroke damage to the primary visual cortex (V1) causes a loss of vision known as hemianopia or cortically-induced blindness (CB). While early, spontaneous, perimetric improvements can occur, by 6 months post-stroke, the deficit is considered chronic and permanent. Despite evidence from sensorimotor stroke showing that early injury responses heighten neuroplastic potential, to date, rehabilitation research has focused only on chronic CB patients. Consequently, little is known about the functional properties of subacute, post-stroke visual systems, and whether they can be harnessed to enhance visual recovery. Here, for the first time, we show that conscious visual discrimination abilities are partially preserved inside subacute, perimetrically-defined blind fields, disappearing by 6 months post-stroke. Complementing this discovery, we show that global motion discrimination training initiated subacutely leads to comparable magnitude of recovery as that initiated in chronic CB. However, it does so 6 times faster, generalizes to deeper, untrained regions of the blind field, and to other [untrained] aspects of motion perception, preventing their degradation upon reaching the chronic period. Untrained subacutes exhibited only spontaneous improvements in perimetry -spontaneous recovery of motion discriminations was never observed.Thus, in CB, the early post-stroke period appears characterized by gradual -rather than suddenloss of visual processing. Subacute training stops this degradation, and is dramatically more efficient at eliciting recovery than identical training in the chronic period. Finally, spontaneous improvements in subacutes appear restricted to luminance detection, whereas recovering discrimination abilities requires deliberate training. Simply stated, after an occipital stroke, "time is VISION".

“…Overall, the intervention in all studies was well monitored and supported the aim of the studies. As all studies included chronic stroke survivors to avoid contamination with other recovery potentials following stroke [34]. Blinded assessments were reported in most studies to reduce or eliminate bias even though in most studies it was a single-blinded design [35].…”

Constraint-Induced Movement Therapies (CIMTs) including the original Constraint-Induced Movement Therapy (CIMT) and the Modified Constraint-Induced Movement Therapy (mCIMT) gained considerable popularity as a treatment approach for upper extremity rehabilitation among patients with mild-to-moderate stroke. However, a major barrier in rehabilitation generally and in CIMTs specifically; is the limited objectivity of some commonly used outcome measures and lack sensitivity to define "True" recovery vs. compensation. Thereby, they may not sufficiently detect of long term consequences and the associated neurological recovery. An essential approach to overcome such barrier is to better understand functional motor recovery, associated neural changes and how they may relate to recovery of the pre-morbid movement pattern. Such Understanding for these relationships would add more in-depth insights on the functional relevance of plastic brain changes in stroke following CIMTs to optimize the field of neuro-rehabilitation. This review synthesizes findings from studies to on the use of the CIMTs including CIMT and mCIMT as efficient practice in the management of upper limb dysfunction following a stroke. The analysis will include (1) the functional recovery and (2) the cortical reorganization following the use of mCIMT and CIMT on patients in the chronic stage following stroke.

“…The location and volume or extent of cerebral infarction determine neurologic deficits in stroke patients especially in sensorimotor, cognitive and emotional functions. The infarction in the cerebellum can affect some brain systems that can lead to complex neurological syndromes, such as apraxia, inability to notice the limb side space, and Gerstman syndrome [3].…”

Objective: To analyze factors related with neurologic deficits to patients with ischemic stroke in Seruni Central of Ulin Hospital Banjarmasin. Methods: Analytical observational study with cross sectional approach, population and sample were outpatient ischemic stroke in Ulin Hospital. Taken sampling technique with accidental sampling in 13 March-30 April 2017 amounted 30 people. Data collection used observation sheets, used two statistical analyzes is Mann Whitney Test and Pearson Correlation Test on the degree of confidence 95% Result: Respondents with right hemisphere lesion 13 people (43.3%), left hemisphere lesion 17 people (56.7%). The mean lesion area is 3.54 cm³, the minimum lesion area is 0.015 cm³, the maximum lesion area is 13.60 cm³. Neurologic deficit (NIHSS 48 hours) was obtained on mean score 10.72, minimum NIHSS score 3 and maximum NIHSS score 29. Conclusion: There is corrrelation between the location of the lesion and the neurologic deficit in ischemic stroke patients in Ulin Hospital Banjarmasin (p=0,000 ≤ 0,05). There is correlation between the extent of the lesion and the neurologic deficit in ischemic stroke patients in Ulin Hospital Banjarmasin (r= 0,910; p= 0,000 ≤ 0,05).
