Neuroanatomical profile of hemineglect in patient’s body image modification


Background: NSU is generally caused by right cerebral hemisphere lesions with a preeminent localization on the frontoparietal lobe.

Aim: To assess the correlation between the typology and the brain lesion site and the consensual consent modality of body image modification after an integrated rehabilitative and neuropsychological treatment.

Setting: A rehabilitation institute for the treatment of neurological gait disorders and neuropsichological failures.

Methods: Patients recruited were divided according to the brain lesion site into 3 groups (IG = ischemic group = 5 patients; HG = hemorrhagic group = 4 patients; IG + HG = ischemic + hemorrhagic group = 3 patients) based on CT brain performed in the post-acute phase. At time T0, the patients recruited underwent a systematic review of their current neuroradiological profile (location delineation and type of brain injury) compared with a consensual framing of the neuromotor and neuropsychological profile acquired at the time of taking charge in the ward. At time T1 and after the drafting and implementation of the rehabilitation treatment plan foreseen in the study (1 to 4 months after T0), the patients in our sample underwent a re-evaluation of their neuromotor and neuropsychological profile with controls of the same outcome parameters considered at time T0

Results: A parametrically but not statistically significant modification of the results obtained was observed by measuring the MI ULl, MI LLl and TCT scales in the group with hemorrhagic brain injury; the analysis of variance did not show any statistical significance in the relationship between the type of stroke (ischemic, hemorrhagic or both) and the motor impairment passing from time T0 to time T1. The analysis of variance did not reveal a statistically or parametrically significant relationship between the type (ischemic, hemorrhagic and ischemic + hemorrhagic) of cerebral stroke and the variations of the neuropsychological profile. The T-Student test showed statistically significant changes in the importance of the lesion site in defining the degree of motor disability. In particular, we observed, about the presence of frontal lobe lesions, a statistically significant variation passing from the T0 time to the T1 time for the following motor scales in 9 of 12 recruited patients: MI LLl (26.4 vs. 62, with p < 0.05), TCT (43.6 vs. 80.6, with p < 0.01 for equal variance assumed and p < 0.05 for equal variance not assumed), FAC (0.8 vs. 2.3 with p < 0,01 for equal variance assumed and p < 0.05 for equal variance not assumed).

Conclusion: We have confirmed the importance of the anatomical-dysfunctional correlation as a key concept from which to start in any neurorehabilitative treatment approach. Our work has highlighted the basic role of the right frontal lobe in the programming and execution of the gesture and its kinesthetic control as regards the left lower limb and the trunk.
