Speeding ability: a new indicator for patients’ independence while walking in everyday life’s situations
No full textAfter discharge home the patients need to master the local road traffic to guarantee mobility and sustain social contacts in order to achieve their vocational reintegration. The walking ability is typically assessed by means of the Functional Ambulation Category (FAC), which gives a good figure of the patients’ ability in a controlled environment, but does not indicate the patients’ real walking in dependence in everyday life’s situations. Aim: To suggest a new indicator to easily quantify the patients’ walking ability in everyday life situations. Materiali e Metodi: 0 chronic stroke patients were enrolled. All were assessed by a 10 m Walking Test and a 6 min Walking Test. The 10 m Walking Test provided the maximum walking speed. The 6 min Walking Test the self selected walking speed.Speeding ability was calculated as the difference between maximum and self selected speed. 5 categories of ADL walking were created. To validate the ategories patients performed a timed walking test in a ADL situation. A chi squared test was used to validate the categories statistically with p<0.05. Risultati: Based upon the speeding ability all the patients got allocated in one of the five categories of ADL walking. All patients performed the timed walking test in ADL situation. The Chi Squared Test showed that the patients responded to the ADL walking test based upon their speeding ability. Conclusione: The speeding ability is a simple indicator for assessing walking ability in everyday life situations. Future work shall focus on this indicator corresponding to an improvement of safety, balance and symmetry while walking
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Combined transcranial direct current stimulation and robot-assisted gait training in patients with chronic stroke: a preliminary comparison.
No full textOBJECTIVE: To evaluate whether robot-assisted gait training combined with transcranial direct current stimulation is more effective than robot-assisted gait training alone or conventional walking rehabilitation for improving walking ability in stroke patients. DESIGN: Pilot randomized clinical trial. SETTING: Rehabilitation unit of a university hospital. SUBJECTS: Thirty patients with chronic stroke. INTERVENTIONS: All patients received ten 50-minute treatment sessions, five days a week, for two consecutive weeks. Group 1 (n = 10) underwent a robot-assisted gait training combined with transcranial direct current stimulation; group 2 (n = 10) underwent a robot-assisted gait training combined with sham transcranial direct current stimulation; group 3 (n = 10) performed overground walking exercises. MAIN MEASURES: Patients were evaluated before, immediately after and two weeks post treatment. Primary outcomes: six-minute walking test, 10-m walking test. RESULTS: No differences were found between groups 1 and 2 for all primary outcome measures at the after treatment and follow-up evaluations. A statistically significant improvement was found after treatment in performance on the six-minute walking test and the 10-m walking test in favour of group 1 (six-minute walking test: 205.20 ± 61.16 m; 10-m walking test: 16.20 ± 7.65 s) and group 2 (six-minute walking test: 182.5 ± 69.30 m; 10-m walking test: 17.71 ± 8.20 s) compared with group 3 (six-minute walking test: 116.30 ± 75.40 m; 10-m walking test: 26.30 ± 14.10 s). All improvements were maintained at the follow-up evaluation. CONCLUSIONS: In the present pilot study transcranial direct current stimulation had no additional effect on robot-assisted gait training in patients with chronic stroke. Larger studies are required to confirm these preliminary findings

Abstract
PURPOSE: To evaluate the role of topical mitomycin C in corneal wound healing (CWH) after photorefractive keratectomy (PRK) in highly myopic eyes.
DESIGN: Prospective, double-masked, randomized clinical trial.
PARTICIPANTS: Seventy-two eyes of 36 patients affected by high (>7 diopters) myopia.
METHODS: In each patient, one eye was randomly assigned to PRK with intraoperative topical 0.02% mitomycin C application, and the fellow eye was treated with a placebo. Postoperatively, mitomycin C-treated eyes received artificial tears (3 times daily, tapered in 3 months), whereas the fellow eye was treated with fluorometholone sodium 2% and artificial tears (3 times daily, tapered in 3 months).
MAIN OUTCOME MEASURES: Uncorrected visual acuity (UCVA) and best-corrected visual acuity (BCVA), contrast sensitivity, manifest refraction, and biomicroscopy. Contrast sensitivity was determined using the Pelli-Robson chart. Corneal confocal microscopy documented CWH.
RESULTS: Mean follow-up was 18 months (range, 12-36). No side effects or toxic effects were documented. At 12-month follow-up examination, UCVAs (logarithm of the minimum angle of resolution) were 0.4+/-0.48 and 0.5+/-0.53 (P = .03) in mitomycin C-treated eyes and corticosteroid-treated eyes, respectively. At 1 year, corneal haze developed in 20% of corticosteroid-treated eyes, versus 0% of mitomycin C-treated eyes. At 12, 24, and 36 months, corneal confocal microscopy showed activated keratocytes and extracellular matrix significantly more evident in untreated eyes (Ps = 0.004, 0.024, and 0.046, respectively).
CONCLUSION: Topical intraoperative application of 0.02% mitomycin C can reduce haze formation in highly myopic eyes undergoing PRK.

Does robotic gait training improve balance in Parkinson's disease? A randomized controlled trial.
No full textBACKGROUND: Treadmill training (with or without robotic assistance) has been reported to improve balance skills in patients with Parkinson's disease (PD). However, its effectiveness on postural instability has been evaluated mainly in patients with mild to moderate PD (Hoehn & Yahr stage ≤3). Patients with more severe disease may benefit from robot-assisted gait training performed by the Gait-Trainer GT1, as a harness supports them with their feet placed on motor-driven footplates. The aim of this study was to determine whether robot-assisted gait training could have a positive influence on postural stability in patients with PD at Hoehn & Yahr stage 3-4.
METHODS: Thirty-four patients with PD at Hoehn & Yahr stage 3-4 were randomly assigned into two groups. All patients received twelve, 40-min treatment sessions, three days/week, for four consecutive weeks. The Robotic Training group (n = 17) underwent robot-assisted gait training, while the Physical Therapy group (n = 17) underwent a training program not specifically aimed at improving postural stability. Patients were evaluated before, immediately after and 1-month post-treatment. Primary outcomes were: Berg Balance scale; Nutt's rating.
RESULTS: A significant improvement was found after treatment on the Berg Balance Scale and the Nutt's rating in favor of the Robotic Training group (Berg: 43.44 ± 2.73; Nutt: 1.38 ± 0.50) compared to the Physical Therapy group (Berg: 37.27 ± 5.68; Nutt: 2.07 ± 0.59). All improvements were maintained at the 1-month follow-up evaluation.
CONCLUSIONS: Robot-assisted gait training may improve postural instability in patients with PD at Hoehn & Yahr stage 3-4
Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
