Use of Nintendo Wii Balance Board for posturographic analysis of Multiple Sclerosis patients with minimal balance impairment

Background: The Wii Balance Board (WBB) has been proposed as an inexpensive alternative to laboratory-grade Force Plates (FP) for the instrumented assessment of balance. Previous studies have reported a good validity and reliability of the WBB for estimating the path length of the Center of Pressure. Here we extend this analysis to 18 balance related features extracted from healthy subjects (HS) and individuals affected by Multiple Sclerosis (MS) with minimal balance impairment. Methods: Eighteen MS patients with minimal balance impairment (Berg Balance Scale 53.3 ± 3.1) and 18 age-matched HS were recruited in this study. All subjects underwent instrumented balance tests on the FP and WBB consisting of quiet standing with the eyes open and closed. Linear correlation analysis and Bland-Altman plots were used to assess relations between path lengths estimated using the WBB and the FP. 18 features were extracted from the instrumented balance tests. Statistical analysis was used to assess significant differences between the features estimated using the WBB and the FP and between HS and MS. The Spearman correlation coefficient was used to evaluate the validity and the Intraclass Correlation Coefficient was used to assess the reliability of WBB measures with respect to the FP. Classifiers based on Support Vector Machines trained on the FP and WBB features were used to assess the ability of both devices to discriminate between HS and MS. Results: We found a significant linear relation between the path lengths calculated from the WBB and the FP indicating an overestimation of these parameters in the WBB. We observed significant differences in the path lengths between FP and WBB in most conditions. However, significant differences were not found for the majority of the other features. We observed the same significant differences between the HS and MS populations across the two measurement systems. Validity and reliability were moderate-to-high for all the analyzed features. Both the FP and WBB trained classifier showed similar classification performance (>80%) when discriminating between HS and MS. Conclusions: Our results support the observation that the WBB, although not suitable for obtaining absolute measures, could be successfully used in comparative analysis of different populations

A specifically designed aquatic exercise protocol to reduce chronic lower limb edema

Objective Despite the fact that muscle pump activation is known to positively impact chronic lower limb edema, objective measurements of standardized exercises for venous-lymphatic rehab are lacking. The aim of this investigation is to determine the effectiveness of an addressed physical activity exploiting the advantages of an aquatic environment.Material and methods Thirty-two lower limbs of 16 patients affected by bilateral chronic leg swelling were included (12 females, 4 males). All the patients underwent a protocol of five sessions of physical exercises specifically conceived inside a pool. Volumetry, subcutaneous thickness, ankle range of motion and symptomatology were assessed as outcome measures.Results One week after the end of the protocol, the average reduction in lower limb volume was 303.1369.72ml (p=0.00002) and 334.38 +/- 62.50ml (p=0.000003) in the right and left legs, respectively. Ankle range of motion and feeling of heaviness significantly improved.Conclusion A specifically designed aquatic protocol is able to positively impact chronic leg swelling offering a first line rehab for this medical condition

SIAMOC position paper on gait analysis in clinical practice: General requirements, methods and appropriateness. Results of an Italian consensus conference

Gait analysis is recognized as a useful assessment tool in the field of human movement research. However, doubts remain on its real effectiveness as a clinical tool, i.e. on its capability to change the diagnostic-therapeutic practice. In particular, the conditions in which evidence of a favorable cost-benefit ratio is found and the methodology for properly conducting and interpreting the exam are not identified clearly. To provide guidelines for the use of Gait Analysis in the context of rehabilitation medicine, SIAMOC (the Italian Society of Clinical Movement Analysis) promoted a National Consensus Conference which was held in Bologna on September 14th, 2013. The resulting recommendations were the result of a three-stage process entailing i) the preparation of working documents on specific open issues, ii) the holding of the consensus meeting, and iii) the drafting of consensus statements by an external Jury. The statements were formulated based on scientific evidence or experts' opinion, when the quality/quantity of the relevant literature was deemed insufficient. The aim of this work is to disseminate the consensus statements. These are divided into 13 questions grouped in three areas of interest: 1) General requirements and management, 2) Methodological and instrumental issues, and 3) Scientific evidence and clinical appropriateness. SIAMOC hopes that this document will contribute to improve clinical practice and help promoting further research in the field

The effects of repetitive arm training combined with functional electrical stimulation on upper extremity motor recovery in sub-acute stroke survivors

Lo studio è un Work Package (responsabile dott.ssa S. Straudi) nell'ambito di un Progetto Strategico Regione Emilia Romagna (coordinatore Prof. N Basaglia). Lo scopo di questo studio randomizzato controllato è di valutare l’efficacia in stroke sub-acuti di interventi riabilitativi intensivi dell’arto superiore a confronto con un protocollo riabilitativo tradizionale. Lo studio mira inoltre a identificare eventuali modificazioni di biomarkers emodinamici, metabolici e circolanti riferiti alla neuroplasticità a seguito dei trattamenti riabilitativi
