In order to develop evidence-based rehabilitation protocols post-stroke, one must first reconcile the vast heterogeneity in the post-stroke population and develop protocols to facilitate motor learning in the various subgroups. The main purpose of this study is to show that auditory constraints interact with the stage of recovery post-stroke to influence motor learning. We characterized the sta...

BACKGROUND Spastic gait is a key feature in patients with hereditary spastic paraparesis, but the gait characterization and the relationship between the gait impairment and clinical characteristics have not been investigated. OBJECTIVES To describe the gait patterns in hereditary spastic paraparesis and to identify subgroups of patients according to specific kinematic features of walking. M...

A 68-year-old man was evaluated with progressive gait difficulties, first noticed three years before. Neurological examination disclosed paraparetic spastic gait and lower limbs hyperreflexia with bilateral Babinski sign; mild left upper limb cerebellar ataxia; and left hearing loss. The magnetic resonance imaging (MRI) showed rims of hypointensity on T2 around the brainstem, cerebellum, and sp...

The results of applying the Wartenberg pendulum test to the assessment of muscle tone in populations of stroke and Parkinsonian patients are described. The test was able to distinguish between increased muscle tone of the spastic or rigid type. The Parkinsonian patients showed a marked reduction of the maximum velocity of the leg swing, with the relaxation index tending to a value of about one....

Hereditary spastic paraplegia (HSP) is a diverse group of single-gene disorders that share the predominant clinical feature of progressive lower limb spasticity and weakness. More than 70 different genetic subtypes have been described and all modes of inheritance are possible. Intellectual dysfunction in HSP is frequent in recessive forms but rare in dominant families. It may manifest by either...

A 44-year-old man presented with 1 year of gradually progressive lower limb weakness and numbness and bowel and bladder incontinence. Neurologic examination revealed a T8 spinal sensory level and spastic paraparesis. Preoperative imaging (figure) of the thoracic spine revealed the scalpel sign, a radiologic entity diagnostic of a dorsal thoracic arachnoid web. The lesion was surgically and hist...

Adams-Oliver syndrome (AOS) is a rare congenital disorder, characterized by aplasia cutis congenita (ACC) of the scalp and variable degrees of terminal transverse limb defects. In this article, a newborn infant diagnosed as AOS for a large scalp defect, acrania, and finger malformations is presented. The patient was hospitalized and the scalp defect was successfully repaired with several surgic...

Classifications of gait and postural patterns in spastic hemiplegia and spastic diplegiía are presented, based on the work of previous authors. The classifications are used as a biomechanical basis, linking spasticity, musculoskeletal pathology in the lower limbs, and the appropriate intervention strategies. The choice of target muscles for spasticity management, the muscle contractures requiri...

Hereditary spastic paraplegia is a group of clinically and genetically heterogeneous neurodegenerative disorders, often characterized by weakness and spasticity in the lower limbs. In our study, we describe a spastic paraplegia type 7 patient with an expanded phenotype who was diagnosed after the discovery of pathogenic variants in SPG7.
