A pilot study of fascia Bowen therapy for 8-11 year-old boys with developmental coordination disorder.

BACKGROUND: Developmental coordination disorder (DCD), also known as dyspraxia, is a disorder emerging in childhood characterised by motor skill impairments. The motor difficulties often produce negative effects in other areas of life, such as poor self-esteem and reduced social interactions. One treatment used for DCD is fascia Bowen therapy, which involves stimulating the fascia tissues of the body using finger and thumb rolling movements over the skin to improve overall muscle movement. However, no studies to date have been reported testing the effectiveness of fascia Bowen in DCD. METHODS: The present pilot study tested the effectiveness of 6 weeks of fascia Bowen in 10 boys aged 8-11 years with DCD. None of the boys had ever received treatment in any form before this study. Motor skills were assessed using the Movement Assessment Battery for Children-2 (MABC-2) and the DCD questionnaire, and psycho-social functioning was measured using the Self-Perception Profile, Spence Social Skills Questionnaire, and Strengths and Difficulties Questionnaire. All measures of interest were assessed before and after the therapy. RESULTS: Results showed significant improvement in motor function post-intervention, with 60% of the children no longer clinically being classified as having a movement difficulty on the MABC-2. However, no significant improvements were seen in psycho-social measures, at least within the short time-frame of the therapy in the current study. CONCLUSIONS: The current pilot study revealed improvements in motor functioning after fascia Bowen therapy, across both performance and questionnaire measures, but that these improvements did not extend to wider areas of life. Further research in DCD is needed to test the effectiveness of fascia Bowen in larger studies with expanded ages and both genders over longer periods, including the generalisation of results of these longer interventions to different areas of life beyond motor ability.

Left parietal cortex transcranial direct current stimulation enhances gesture processing in corticobasal syndrome.

BACKGROUND AND PURPOSE: Corticobasal syndrome (CBS) is a clinical entity characterized by higher cortical dysfunctions associated with asymmetric onset of levodopa-resistant parkinsonism, dystonia and myoclonus. One of the most typical and distressful features of CBS is limb apraxia, which affects patients in their everyday life. Transcranial direct current stimulation (tDCS) is a non-invasive procedure of cortical stimulation, which represents a promising tool for cognitive enhancement and neurorehabilitation. The present study investigated whether anodal tDCS over the parietal cortex (PARC), would improve ideomotor upper limb apraxia in CBS patients. METHODS: Fourteen patients with possible CBS and upper limb apraxia were enrolled. Each patient underwent two sessions of anodal tDCS (left and right PARC) and one session of placebo tDCS. Ideomotor upper limb apraxia was assessed using the De Renzi ideomotor apraxia test that is performed only on imitation. RESULTS: A significant improvement of the De Renzi ideomotor apraxia test scores (post-stimulation versus pre-stimulation) after active anodal stimulation over the left PARC was observed (χ(2) = 17.6, P = 0.0005), whilst no significant effect was noticed after active anodal stimulation over the right PARC (χ(2) = 7.2, P = 0.07). A post hoc analysis revealed a selective improvement in the De Renzi ideomotor apraxia score after active anodal stimulation over the left PARC compared with placebo stimulation considering both right (P = 0.03) and left upper limbs (P = 0.01). CONCLUSIONS: These findings indicate that tDCS to the PARC improves the performance of an ideomotor apraxia test in CBS patients and might represent a promising tool for future rehabilitation approaches.

Antioxidant and α-Glucosidase Inhibitory Properties and Chemical Profiles of Moroccan Propolis.

The chemical profiles of propolis hydroalcoholic extracts from different regions of Morocco were studied by gas chromatography coupled to mass spectrometry after silylation. Samples from Khamissat and Imouzzer belong to the poplar type, as typical poplar flavonoids predominated. Propolis from Rabat also contained high percentage of flavonoids, but had significantly lower amount of phenolic acid esters and contained no pinobanksin-3-O-acetate. Propolis from Bhalil demonstrated a profile rich in diterpenes (74.3%), and is a typical Mediterranean propolis sample. All samples had the capacity for inhibiting glucosidase and amylase enzymes, as well as the capacity for scavenging free radicals and preventing lipid peroxidation. Both activities were significantly higher in the flavonoids-rich samples.

Improving ideomotor limb apraxia by electrical stimulation of the left posterior parietal cortex.

Limb apraxia, a deficit of planning voluntary gestures, is most frequently caused by damage to the left hemisphere, where, according to an influential neurofunctional model, gestures are planned, before being executed through the motor cortex of the hemisphere contralateral to the acting hand. We used anodal transcranial direct current stimulation delivered to the left posterior parietal cortex (PPC), the right motor cortex (M1), and a sham stimulation condition, to modulate the ability of six left-brain-damaged patients with ideomotor apraxia, and six healthy control subjects, to imitate hand gestures, and to perform skilled hand movements using the left hand. Transcranial direct current stimulation delivered to the left PPC reduced the time required to perform skilled movements, and planning, but not execution, times in imitating gestures, in both patients and controls. In patients, the amount of decrease of planning times brought about by left PPC transcranial direct current stimulation was influenced by the size of the parietal lobe damage, with a larger parietal damage being associated with a smaller improvement. Of interest from a clinical perspective, left PPC stimulation also ameliorated accuracy in imitating hand gestures in patients. Instead, transcranial direct current stimulation to the right M1 diminished execution, but not planning, times in both patients and healthy controls. In conclusion, by using a transcranial stimulation approach, we temporarily improved ideomotor apraxia in the left hand of left-brain-damaged patients, showing a role of the left PPC in planning gestures. This evidence opens up novel perspectives for the use of transcranial direct current stimulation in the rehabilitation of limb apraxia.

Dyspraxia series: Part Two. One step forward.

Dyspraxia is an often under-diagnosed problem that describes a difficulty in managing certain motor tasks. It's an impairment of the organisation of movement and also an immaturity in the way the brain processes information. This immaturity results in messages not being properly or fully transmitted. In brief, dyspraxia affects the planning of what to do and how to do it and is associated with problems of perception, language and thought. There are a variety of causes and therapy based on the knowledge of these allow affected individuals to reach their full developmental potential.

A new approach to rhythm cueing of cognitive functions: the case of ideomotor apraxia.

Although positive effects of rhythm cueing on motor control in neurologic disorders are known, no studies have yet focused on patients suffering from impaired programming of complex actions. One patient suffering from ideomotor apraxia (a potentially ideal experimental paradigm to test the effect of rhythm on high-level motor control) underwent two rehabilitation training sets differing only for the presence or absence of rhythm cueing. Both sets of training increased the patient's proficiency, but rhythm cueing was significantly more effective, during the training as well as during the post-training uncued test. Ideomotor apraxia represents an effective model to test the effects of rhythm on high-level motor control.

[Limb apraxia]. / Die Gliedmassenapraxie.

Apraxia is the disturbance of planning and of execution of motor activity. It is not caused by a lesion or a disturbance of the motor or sensory nervous system, it is elicited by a dysfunction of an area in the left cortex of the brain. This area in the left fronto-parietotemporal hemisphere is located right beside the area for speech. Therefore it is not unusual that patients with apraxia suffer from aphasia as well. The two different types of limb apraxia are ideomotor apraxia and ideational apraxia. Ideomotor apraxia is apraxia without tool use, it includes imitation of positions of hands and fingers, performance of gestures on demand, and pantomime of object use. Ideational apraxia is apraxia with tool use like cutting with a knife or utilizing a pencil.

Apraxia of speech: an overview.

Apraxia of speech (AOS) is a motor speech disorder that can occur in the absence of aphasia or dysarthria. AOS has been the subject of some controversy since the disorder was first named and described by Darley and his Mayo Clinic colleagues in the 1960s. A recent revival of interest in AOS is due in part to the fact that it is often the first symptom of neurodegenerative diseases, such as primary progressive aphasia and corticobasal degeneration. This article will provide a brief review of terminology associated with AOS, its clinical hallmarks and neuroanatomical correlates. Current models of motor programming will also be addressed as they relate to AOS and finally, typical treatment strategies used in rehabilitating the articulation and prosody deficits associated with AOS will be summarized.

Apraxia of lid opening is alleviated by pallidal stimulation in a patient with Parkinson's disease.

Apraxia of lid opening (ALO) is a syndrome characterized by a non-paralytic inability to open the eyes at will in the absence of visible contraction of the orbicularis oculi muscle. Here we report that globus pallidus internus deep brain stimulation on the right side markedly alleviates ALO as well as gait freezing in a patient with Parkinson's disease.
