Long-term effect of epoetin alfa on clinical and biochemical markers in friedreich ataxia.

Friedreich ataxia is an autosomal recessive disease with no available therapy. Clinical trials with erythropoietin in Friedreich ataxia patients have yielded conflicting results, and the long-term effect of the drug remains unknown. We designed a double-blind, placebo-controlled, multicenter trial to test the efficacy of epoetin alfa on 56 patients with Friedreich ataxia. The primary endpoint of the study was the effect of epoetin alfa on peak oxygen uptake (VO2 max) at the cardiopulmonary exercise test. Secondary endpoints were frataxin levels in peripheral blood mononuclear cells, improvement in echocardiography findings, vascular reactivity, neurological progression, upper limb dexterity, safety, and quality of life. Epoetin alfa or placebo (1:1 ratio) was administered subcutaneously at a dose of 1200 IU/Kg of body weight every 12 weeks for 48 weeks. A total of 56 patients were randomized; 27 completed the study in the active treatment group, and 26 completed the study in the placebo group[KG1]. VO2 max was not modified after treatment (0.01 [-0.04 to 0.05]; P = .749), as well as most of the secondary endpoint measures, including frataxin. The 9-hole peg test showed a significant amelioration in the treatment group (-17.24 sec. [-31.5 to -3.0]; P = .018). The treatment was safe and well tolerated. Although results are not in favor of an effect of epoetin alfa in Friedreich ataxia, this is the largest trial testing its effect. It is still possible that epoetin alfa may show some symptomatic effect on upper-limb performance. This study provides class I evidence that erythropoietin does not ameliorate VO2 max in patients with Friedreich ataxia. © 2016 International Parkinson and Movement Disorder Society.

Animal assisted interventions in neurorehabilitation: a review of the most recent literature

IntroductionWhile conventional wisdom has always affirmed the value of animals in promoting human health and well-being, only recently has their therapeutic role in medicine become a topic for dedicated research. Animal assisted interventions (AAI) can be classified as animal-assisted activities, animal-assisted therapy, and service animal programmes. ObjectiveThe aim of this review is to analyse original papers addressing AAI and neurological diseases and published in the most influential medical journals between 2001 and 2012, and discuss their findings in the light of what may be of interest in the field of neurology. DiscussionWe selected a total of 23 articles on neurorehabilitation in cerebral palsy, pervasive developmental disorders, multiple sclerosis, spinal cord injury, stroke, and mental disorders. The main therapeutic results were improvement on the Gross Motor Function Classification Scale and in upper limb dexterity (cerebral palsy); improvement in social functioning and interaction; reductions in stress, anxiety, and loneliness (pervasive developmental disorders and mental disorders); and decreased spasticity with improved balance (multiple sclerosis, spinal cord injury, stroke). ConclusionThese interventions, performed with highly specialised animals in very specific neurological populations, deliver an increasing body of scientific evidence suggesting that they are an effective complement to other existing therapies. In these diseases, further high-quality studies are warranted in order to define the most appropriate programmes for therapy.

촉각과 온각 자극에 따른 악력, 상지 기민성, 그리고 손 기능의 차이

Abstract The purpose of this study was to investigate difference between grip strength, upper limb dexterity, and hand function according to touch and heat sensory stimulus. Forty healthy men were recruited. After obtaining subjects characteristics, examined grip strength, upper limb dexterity, and hand function, then we made touch sensory input using soft brush and tried the test again. Next day, we made thermal input using hot pack and did retest, too. The result showed significant differences appeared on every variable in grip strength and upper limb dexterity test (p<.001), and significant differences appeared on every variable except lifting small objects in hand function (p<.01). In conclusion, sensory input is to increase grip strength, upper limb dexterity, and hand function. The thermal sensory input has a tendency to increase grip strength, upper limb dexterity, and hand function than that of touch sensory input in effect of stimulus classification. The application of proper stimulus helps to facilitate upper limb and hand function in rehabilitation and in industrial field. So it is necessary to try more tests of frequency and intensity of stimulus.

Early development in Williams syndrome

The aim of the present study was to gain a better understanding of the motor performance in Williams syndrome for early intervention of rehabilitation programs. Eleven Williams syndrome patients were evaluated from the pediatric clinics. Seven patients younger than 42 months were evaluated with the Bayley II Test for mental development index (MDI) and psychomotor development index (PDI). Four patients older than 42 months were evaluated with the Bruininks-Oseretsky Test (short form) of motor profile. The raw scores were measured and converted to the standard scores for comparison. A significantly mental and psychomotor development delay of 6.1 and 5.7 months individually was found compared to that of the mean age (P > 0.0047 and 0.0053). Juvenile Williams syndrome patients were apparently retarded (<10 per thousand rank) in motor development in comparison with persons of the same age. The results showed that motor performance was severely delayed not only in Williams syndrome children but also in Williams syndrome juveniles. It is important for clinicians to work out a comprehensive plan to help the motor development of patients with Williams syndrome in addition to treating their medical problems, and upper limb dexterity may be the goal for training.
