BACKGROUND: Robotic rehabilitation devices for upper limb function (ULF) provide global indicators of a patient's ability, but the temporal evolution of motion related to motor control is disregarded. OBJECTIVE: To determine normative values for indices of accuracy, speed and smoothness in the evaluation of upper limb function. METHODS: Twenty-five healthy individuals performed the Armeo ® Spring device "Vertical Capture" task. Custom stand-alone software was developed to provide the following indices: global Hand Path Ratio (HPR), local HPR in the target area (locHPR), vertical and horizontal overshoot (vertOS, horOS), maximum and mean velocity (maxVel, meanVel), mean/maximum velocity, number of peaks in velocity profiles (NVelPeaks) and normalized jerk (NormJerk). The dependence of indices on task characteristics was analyzed by an ANCOVA test. Indices inner relationships were assessed by a correlation and a factor analysis. Normative values were then provided. RESULTS: 4,268 single reaching movements were analyzed. Four indices were not affected by movement direction. Indices were minimally influenced by the difficulty level. Based upon correlation and factor analysis indices and can be grouped into three assessment fields, dealing with precision, velocity and smoothness. CONCLUSIONS: We have developed a tool to assess ULF in dynamic condition. Normative values were obtained to be used as references in assessing patients.
ACS, containing endogenous anti-inflammatory cytokines including IL-1RA and several growth factors, could reduce pain and increase function and mobility in mild to moderate knee OA. AREA OF CONTROVERSY: Given the limited data available on the composition of ACS, the mechanisms through which ACS produces clinical improvement, the duration of its effect and the changes in cytokine levels after repeated injections are still unknown. Growing points Although previous clinical data are encouraging and confirm the safety of this modality, given the limitations of current studies, there should be additional, controlled trials to further confirm efficacy for the use of ACS in OA treatment. AREA TIMELY FOR DEVELOPING RESEARCH: ACS can lead to enhancement of tissue regeneration and to reduction of degenerative mechanisms.
Objective. To propose a rehabilitation protocol able to produce immediate and long-term beneficial effects on level of disability and overall performance in ADLs. Materials and Methods. Forty-one FM patients were randomized to an exercise and educational-behavioral programme group (experimental group, EG = 21) or to a control group (CG = 20). Each subject was evaluated before, at the end (T1), and after 6 months (T6) from the conclusion of the rehabilitation treatment using the Fibromyalgia Impact Questionnaire (FIQ), the visual analogue scale (VAS), the Health Assessment Questionnaire (HAQ), the fatigue severity scale (FSS), the 6-minute walking test (6MWT), tender points count (TPC), and spinal active range of motion. The exercise protocol included 20 sessions consisting in self-awareness, stretching, strengthening, spine flexibility, and aerobic exercises, which patients were subsequently educated to perform at home. Results. The two groups were comparable at baseline. At T1, the EG showed a positive trend in FIQ, VAS, HAQ, and FSS scales and significant improvement in 6MWT and in most spinal active range of motion measurements (P between 0.001 and 0.04). The positive results were maintained at the follow-up. Conclusion. The proposed programme was well tolerated and produced immediate and medium-term beneficial effects improving function and strain endurance. This trial is registered with DRKS00005071 on DRKS.
Exercise is considered a fundamental tool for the management of ankylosing spondylitis (AS), in combination with pharmacological therapy that with the advent of biological therapy has improved dramatically the control of signs and symptoms of this challenging disease. Current evidence shows that a specific exercise protocol has not been validated yet. The purpose of this review is to update the most recent evidence (July 2010-November 2013) about physiotherapy in AS, analyzing the possible role and synergistic interactions between exercise and biological drugs. From 117 studies initially considered, only 15 were included in the review. The results support a multimodal approach, including educational sessions, conducted in a group setting, supervised by a physiotherapist and followed by a maintaining home-based regimen. Spa exercise and McKenzie, Heckscher, and Pilates methods seem promising in AS rehabilitation, but their effectiveness should be further investigated in future randomized controlled trials (RCTs). When performed in accordance with the American College of Sports Medicine guidelines, cardiovascular training has been proven safe and effective and should be included in AS rehabilitation protocols. Exercise training plays an important role in the biological era, being now applicable to stabilized patients, leading ultimately to a better management of AS by physiatrists and rheumatologists throughout the world. On the basis of the current evidence, further research should aim to determine which exercise protocols should be recommended.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
