Abstract

Balance disorders related to disturbances in perception of spatial reference systems are common especially after right hemispheric stroke. Mental misrepresentation of bodily orientation in space is then often superimposed upon other factors affecting imbalance such as motor and sensory impairments. Traditional rehabilitation for balance recovery has not been specifically designed to improve balance disorders related to spatial cognition. The traditional approach, consisting of stimulating the conscious perception of body orientation in space, is demanding and laborious. The approach based on sensorial stimulation is completely different. The relevance of this method lies in the fact that, firstly it is specifically active in the cognitive component of balance disorders; and secondly, it can passively be applied with minimal patient participation, which is of particular importance for this patient group characterized by disorders of attention and concentration. These techniques, such as proprioceptive, visual or vestibular stimulation, have been found to correct spatial neglect but also postural bias. Clinical and data from functional neuro-imaging suggest a direct central action on cortical structures involved in the elaboration of spatial representation. These are promising techniques for the rehabilitation of postural disturbances related to spatial cognition disorders but are as yet at the stage of preliminary results., (Copyright © 2015 Elsevier Masson SAS.

Abstract

International audience; Introduction The asymmetry of support when walking, common after a stroke, is a known risk factor for falls. The objective of this study is to assess effects of muscle vibrations on various sites on correcting this asymmetry. Methods Twenty-one patients (61 ± 13 years) with hemiplegia (10 right, 11 left) chronic vascular (mean time post stroke 48 ± 44months) received vibratory stimulation transcutaneous 70 Hz at the posterior cervical lesion contralateral muscles (NMV), the gluteus medius lesion side (GMV) and the biceps contralateral lesion (sham). An analysis of the percentage of one-foot support measured by GAITRite was performed before, during, and 2 and 10 minutes after each stimulation. Results Before stimulation, supporting asymmetry is noted with a percentage of the push side hemiplegic averaged 31.5% (±6.0%, min = 20%, max = 37%). Under GMV we find that this increases to 35.0% (±5.9%, min = 28.8%, max = 41.2%) against 31.1% (±7.5%, min = 20%, max = 42%) in NMV and 32.0% (±6.9%, min = 28.6%, max = 39.4%) in the sham. 2 minutes, the effect persists for GMV stimulation with 35.5% (±9.0%, min = 35%, max = 42.4%) 4% improvement then disappears in 10 minutes. The results are more significant in left hemiplegia with 7% improvement for GMV (P < 0.005). There is a more moderate effect on the NMV with a post effect at 2 min (32.6%) and 10 min (32.2%). Discussion–conclusion Vibratory stimulations therefore seem to improve support asymmetric walking hemiplegic patients. Different kinetic effect is observed between the cervical stimulation and gluteus medius. These results seem to reflect a different pathophysiology between the gluteus medius and cervical postural muscles. These could act through a central mechanism of spatial cognition while the hip muscles have a more immediate effect proprioceptive device. These analyses were complemented by a 3D gait analysis in an attempt to better understand the mechanisms of adaptation. This is the first study concerned with the effectiveness of vibratory stimulation on dynamic balance
