Abstract: Background: Examining changes in brain activation linked with emotion-inducing stimuli is essential to the study of emotions. Due to the ecological potential of techniques such as virtual reality (VR), inspection of whether brain activation in response to emotional stimuli can be modulated by the three-dimensional (3D) properties of the images is important. Objective: The current study sought to test whether the activation of brain areas involved in the emotional processing of scenarios of different valences can be modulated by 3D. Therefore, the focus was made on the interaction effect between emotion-inducing stimuli of different emotional valences (pleasant, unpleasant …and neutral valences) and visualization types (2D, 3D). However, main effects were also analyzed. Methods: The effect of emotional valence and visualization types and their interaction were analyzed through a 3 × 2 repeated measures ANOVA. Post-hoc t-tests were performed under a ROI-analysis approach. Results: The results show increased brain activation for the 3D affective-inducing stimuli in comparison with the same stimuli in 2D scenarios, mostly in cortical and subcortical regions that are related to emotional processing, in addition to visual processing regions. Conclusions: This study has the potential of clarify brain mechanisms involved in the processing of emotional stimuli (scenarios' valence) and their interaction with three-dimensionality. Show more

Abstract: Background: Limited evidence is available about the effectiveness of virtual reality using low cost commercial consoles for children with developmental delay. Objective: The aim of this preliminary study is to evaluate the usefulness of a videogame system based on non-immersive virtual reality technology (Xbox 360 KinectTM) to support conventional rehabilitation treatment of children with cerebral palsy. Secondarily, to objectify changes in psychomotor status of children with cerebral palsy after receiving rehabilitation treatment in addition with this last generation game console. Methods: 11 children with cerebral palsy were included the study. A baseline, a post-treatment and a …follow-up assessment were performed related to motor and the process skills, balance, gait speed, running and jumping and fine and manual finger dexterity. All the participants completed 8 weeks of videogame treatment, added to their conventional physiotherapy treatment, with Xbox 360 Kinect™ (Microsoft) game console. Results: The Friedman test showed significant differences among the three assessments for each variable: GMFM (p = 0.001), AMPS motor (p = 0.001), AMPS process (p = 0.010), PRT (p = 0.005) and 10 MW (p = 0.029). Wilcoxon test showed significant statistically differences pre and post-treatment, in all the values. Similarly, results revealed significant differences between basal and follow-up assessment. There were not statistical differences between post-treatment and follow-up evaluation, indicating a long-term maintenance of the improvements achieved after treatment. Conclusions: Low cost video games based on motion capture are potential tools in the rehabilitation context in children with CP. Our Kinect Xbox 360 protocol has showed improvements in balance and ADL in CP participants in a school environment, but further studies are need to validate the potential benefits of these video game systems as a supplement for rehabilitation of children with CP.

Abstract: 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. Show more

Abstract: Background: Although the spasticity syndrome is an important sensorimotor disorder, the impact of grade of lower limb muscle hypertonia, spasm and clonus activity on voluntary muscle function, gait and daily activities has not been systematically analysed during subacute and chronic spinal cord injury (SCI). Objective: To determine the prevalence of spasticity signs and symptoms during SCI, and to assess their impact on motor function and activities. Methods: A descriptive transverse study of sixty-six subjects with SCI was performed by assessing injury characteristics, spasticity (modified Ashworth scale, Penn scale, SCATS scale) and motor function (lower limb manual …muscle scores, WISCI II, spinal cord injury spasticity evaluation tool). Results: Most subjects with the spasticity syndrome presented lower limb hypertonia and spasms during both subacute and chronic SCI, interfering with daily life activities. Subjects with incomplete SCI and hypertonia revealed a loss of voluntary flexor muscle activity, while extensors spasms contributed strongly to loss of gait function. The Penn spasms scale no correlated with muscle function or gait. Conclusions: Specific diagnosis of spasm activity during subacute SCI, and its impact on lower limb voluntary muscle activity, gait function and daily activities, is required to develop a more effective neurorehabilitation treatment strategy.

Abstract: Background: Balance and postural control (PC) disorders are frequent motor disorder symptoms associated with multiple sclerosis (MS). Objective: To demonstrate the potential improvements in balance and PC among patients with MS who complete a virtual reality telerehabilitation program that represents a feasible alternative to physical therapy for situations in which conventional treatment is not available. Methods: 50 patients was recruited. Control group (n = 25) received physiotherapy treatment twice a week (40 min per session). Experimental group (n = 25) received telerehabilitation treatment using the Xbox 360® console monitored via videoconference. Experimental group attended 40 …sessions, four sessions per week (20 min per session). The treatment schedule lasted 10 weeks for both groups. A computerised dynamic posturography and clinical outcomes (Berg Balance and Tinettti scales) were used at baseline and at the end of the treatment. Results: Results showed an improvement over general balance in both groups. Visual preference, the contribution of vestibular information, mean response time and Tinetti test yielded significant differences in the experimental group. An ANOVA revealed significant between-group post-treatment differences in the composite equilibrium score, Berg and Tinetti scales in the experimental group. Conclusion: We suggest that our virtual reality program enables anticipatory PC and response mechanisms and might serve as a successful therapeutic alternative in situations in which conventional therapy is not readily available.

Abstract: Background: Gait disorders are common in multiple sclerosis (MS) and lead to a progressive reduction of function and quality of life. Objective: Test the effects of robot-assisted gait rehabilitation in MS subjects through a pilot randomized-controlled study. Methods: We enrolled MS subjects with Expanded Disability Status Scale scores within 4.5–6.5. The experimental group received 12 robot-assisted gait training sessions over 6 weeks. The control group received the same amount of conventional physiotherapy. Outcomes measures were both biomechanical assessment of gait, including kinematics and spatio-temporal parameters, and clinical test of walking endurance (six-minute walk test) and mobility …(Up and Go Test). Results: 16 subjects (n = 8 experimental group, n = 8 control group) were included in the final analysis. At baseline the two groups were similar in all variables, except for step length. Data showed walking endurance, as well as spatio-temporal gait parameters improvements after robot-assisted gait training. Pelvic antiversion and reduced hip extension during terminal stance ameliorated after aforementioned intervention. Conclusions: Robot-assisted gait training seems to be effective in increasing walking competency in MS subjects. Moreover, it could be helpful in restoring the kinematic of the hip and pelvis.

Abstract: Objective: The objective of this study was to compare the effects of action observation training and motor imagery training on recovery from chronic stroke. Methods: Thirty patients who were more than six months post stroke participated in this study and were randomly allocated to three groups. The action observation training group practiced additional action observation training for five 30-minute sessions over a four-week period. The motor imagery training group practiced additional motor imagery training for five 30-minute sessions over a four-week period. The following clinical measures were used for assessment of dynamic balance and gait abilities: Timed Up …and Go Test, Functional Reaching Test, Walking Ability Questionnaire, and Functional Ambulation Category. Spatiotemporal gait parameters were also collected using a GAITRite system. Result: Compared with the physical training group, the action observation training group showed significant improvement in the Timed Up and Go test, gait speed, cadence, and single limb support of the affected side. No significant differences in any of the outcome measures were observed between the action observation training group and the motor imagery training group. Conclusion: Action observation training and motor imagery training results in improvement of dynamic balance and gait ability. These results suggest the feasibility and suitability of action observation training for patients with chronic stroke. Show more

Abstract: Background: Trunk control has been identified as an important early predictor of functional outcome after stroke but there is insufficient evidence that proximal stability of the trunk is a pre-requisite for sitting and standing balance, walking, and functional activities. Objective: We systematically reviewed the literature on trunk training exercises (TTE) in adult patients with stroke. To establish if TTE can improve trunk performance and sitting balance. Methods: CENTRAL, MEDLINE, EMBASE, CINAHL, PEDro, REHABDATA Database, Scielo, Scopus, Web of Science, Trip Database, and Epistemonikos were searched and reference lists screened to identify randomised controlled trials (RCTs) of …trunk training exercises in stroke survivors. Two reviewers independently screened references, selected relevant studies, extracted data, and assessed trial quality. The primary outcomes were trunk performance and sitting balance. Due to the heterogeneity of included studies meta-analysis was not possible. Results: A total of 11 studies with 317 participants were analysed. Trunk training exercises showed a moderate evidence to improve trunk performance and dynamic sitting balance. Conclusions: Trunk training exercises, performed with either stable or unstable surface, could be a good rehabilitation strategy and might help improving trunk performance and dynamic sitting balance after stroke.

Abstract: Background: Mirror therapy (MT) was found to improve motor function after stroke, but its neural mechanisms remain unclear, especially in single stroke patients. Objectives: The following imaging study was designed to compare brain activation patterns evoked by the mirror illusion in single stroke patients with normal subjects. Methods: Fifteen normal volunteers and five stroke patients with severe arm paresis were recruited. Cerebral activations during movement mirroring by means of a video chain were recorded with functional magnetic resonance imaging (fMRI). Single-subject analysis was performed using SPM 8. Results: For normal subjects, ten and thirteen …subjects displayed lateralized cerebral activations evoked by the mirror illusion while moving their right and left hand respectively. The magnitude of this effect in the precuneus contralateral to the seen hand was not dependent on movement speed or subjective experience. Negative correlation of activation strength with age was found for the right hand only. The activation pattern in stroke patients is comparable to that of normal subjects and present in four out of five patients. Conclusions: In summary, the mirror illusion can elicit cerebral activation contralateral to the perceived hand in the majority of single normal subjects, but not in all of them. This is similar even in stroke patients with severe hemiparesis. Show more

Abstract: Background: Abdominal strengthening exercises are important for stroke patients; however, there is a lack of research on therapeutic exercises for increasing abdominal muscle activity in stroke patients. Objective: We investigated the effects of non-paretic arm exercises using a tubing band on abdominal muscle activity in stroke patients. Methods: In total, 18 hemiplegic subjects (13 males, 5 females) were recruited. All subjects performed non-paretic arm exercises involving three different shoulder movements (extension, flexion, and horizontal abduction) using an elastic tubing band. Surface electromyography (EMG) signals were recorded from the rectus abdominis (RA), external oblique (EO), and internal …oblique (IO) muscles bilaterally during non-paretic arm exercises. Results: EMG activities of abdominal muscles during non-paretic arm extension and horizontal abduction were increased significantly versus shoulder flexion when subjects performed the arm exercise in a seated position. Muscle activity of the EO was significantly greater in the paretic than the non-paretic side during non-paretic arm extension and horizontal abduction. Conclusions: We suggest that non-paretic arm extension and horizontal abduction exercises using an elastic tubing band may be effective in increasing abdominal muscle activity. Show more

Abstract: Background: Patients suffering from unilateral neglect syndrome (UNS) are not able to respond to stimuli administered to the side of the body opposite to the lesion. UNS is most commonly seen after right-hemisphere lesions. Patients with UNS experience more problems with activities of daily living and recovery after stroke is delayed. Objective: To investigate which treatment modalities can alleviate the symptoms of UNS after stroke and to determine their effectiveness. Methods: Databases PubMed, Web of knowledge and PEDro have been searched. Quality assessment was conducted using the 9-item Delphi list. Data extraction was performed by the …first author. Effect sizes have been calculated using Cohen's d. Results: 15 RCT's have been included. Most studies used add-on therapies. Almost all studies found improvements in both groups, but only 7 trials showed statistically significant between group differences in favor of the experimental group. Large effect sizes were found in only four studies. Conclusions: All the interventions discussed in this review can reduce the symptoms of UNS. However, TENS, optokinetic stimulation, somatosensory electrostimulation, mirror therapy and virtual reality training seem to be the most effective treatment methods (d > 0,80). Future research should focus on producing studies of higher methodological quality with larger sample sizes. Show more

Abstract: Background: Robotic neurorehabilitation, thanks to high dosage/intensity training protocols, has the potential for a greater impact on impairment. Objective: We aimed to analyze how time since the acute event may influence the motor recovery process during robot-assisted rehabilitation of the upper limb. Methods: A total of 41 patients after stroke were enrolled: 20 in subacute phase, i.e. ≤ 6 months elapsed since their unilateral cerebrovascular accident (CVA), and 21 at chronic stage, i.e. > 6 months since CVA. All subjects underwent 30 minutes of robot-aided rehabilitation twice a day, 5 days a week for at least …three weeks of training. Patients were evaluated at the start and end of treatment using the Fugl-Meyer and Modified Ashworth clinical scales and by a set of robot measured kinematic parameters. The time interval from stroke was considered as a grouping factor to analyze its impact on time course of recovery. Results: After training both groups significantly improved their impairment (F = 44.25, p < 0.001) but sub-acute patients showed a greater improvement on the Fugl-Meyer scale than chronic patients. The time course of recovery of the kinematic variables showed higher time constants of motor improvement in the sub-acute than chronic group, but they were one order lower than spontaneous recovery time constants. Conclusions: Spontaneous recovery seems to have a limited impact on the improvement of sub-acute patients, most of their changes being likely due to re-learning during rehabilitation. In addition, a longer recovery time was required to maximize outcome in sub-acute than in chronic patients. Show more

Abstract: Background: Swallowing disorders affect up to 35–85% of patients with stroke. Dysphagia complications can lead to malnutrition, dehydration, bronchoaspirative pneumonia and death, and have impact on health care costs. Objective: To evaluate the clinical screening capacity of the Volume Viscosity Swallow Test (V-VST) for oropharyngeal dysphagia and aspiration in a homogeneous stroke patient sample. Methods: Cohort study of 52 stroke patients in a subacute phase. Piecemeal deglutition and oropharyngeal residue were considered signs of impaired efficacy and cough, fall in oxygen saturation and voice changes, signs of impaired safety. Sensitivity, specificity, positive and negative predictive values, …accuracy and likelihood ratios were calculated for V-VST results and compared with those of videofluoroscopy (VFS), the gold standard for studies on swallowing disorders. Results: The V-VST is a highly sensitive and specific test to detect aspiration with sensitivity of 88.2% and specificity of 71.4%; negative predictive value was 92.6%; accuracy index was 0.74. Sensitivity and specificity for penetration were 34.3% and 70.6%, respectively; accuracy was 32%. Conclusions: The V-VST is low in cost, easy to use and very sensitive, meeting the requirements of oropharyngeal dysphagia and aspiration screening test in subacute stroke patients. Show more

Abstract: Background: Active information and training improves patient and carer knowledge of stroke and aspects of patient satisfaction, as well as reduces patient depression. Objective: To evaluate the effect of a post-stroke information and carer training intervention provided in the rehabilitation hospital setting on patient and carers' satisfaction. Methods: Nonrandomized, controlled trial with 241 patients consecutively admitted in a post-stroke rehabilitation unit and their carers. The first 140 underwent a standard rehabilitation program (control group) and the 131 following attended an additional class (intervention group). Satisfaction was assessed with the Satisfaction Pound Scale administered by telephone 6 …months after stroke in 74 patients and 85 carers from the control group and in 76 patients and 73 carers from the intervention group. Results: Over 80% of patients in both groups were satisfied with information, care and therapy during hospitalization. The amount of therapy and support at discharge were the issues that arouse greater dissatisfaction. Patient and carers' satisfaction with information, support and accessibility to rehabilitation team after hospital discharge improved after the intervention (p < 0.001). Conclusions: Systematic active information, training and community support provision for stroke patients and carers improves satisfaction with stroke rehabilitation programs and support received after hospital discharge.

Abstract: Background: Assessment of impaired motor behaviour serves as tool for diagnosis and for evaluation of progression of chronic neurodegeneration. Methods: We measured performance of rapid alternating movements, simple and complex motion series with instruments in scored, drug naïve patients with Huntington's disease and controls. Objectives: To compare device outcomes with the ones of controls and to correlate them with each other and with the disease symptoms. Results: Patients showed lower peak velocities and longer intervals for performance of rapid alternating movements than the controls. On the right dominant side, a correlation was found between …intervals needed for standardised alternating movement performance and the simple motion task outcomes in the patients. No relations to the rated disease symptoms appeared. Conclusion: Execution of alternating movements is disturbed in Huntington's disease. Performance of the simple motion task and realisation of alternating motions shares a need for low cognitive efforts. Both ask for a more automated motion execution. Therefore they were related to each other to a certain extent. Execution of complex movement series asks for higher cognitive load, as it demands aiming and planning of movement series with visual input. This motion pattern does not resemble to the realisation of rapid alternating movements. Show more

Abstract: Background: Neuralgic Amyotrophy (NA) is characterized by neuropathic pain, subsequent patchy paresis and possible sensory loss in the upper extremity. Many patients experience difficulties in performing activities of daily life and are unable to resume work. We developed a combined physical- and occupational therapy program for patients recovering from NA. Objective: Evaluation of the effectiveness of a multidisciplinary intervention program for patients with subacute NA. Methods: We performed a within subject proof-of-principle pilot study in eight patients with subacute NA. Patients followed 8 hours of physical and 8 hours of occupational therapy spread over a 16-week …period. Primary outcome measures: The Canadian Occupational Performance Measure (COPM) and Shoulder Rating Questionnaire (SRQ). Secondary outcome measure: Disability of Arm Shoulder and Hand (DASH). Results: Improvements (mean (95% CI)) were found in the performance and satisfaction scores of the COPM +2.3 (0.9–3.7) and +1.4 (0.4–2.4) points, respectively and the SRQ +14.8 (7.4–22.0) points. The majority of patients (6 out of 8) also demonstrated improvements in the DASH. Conclusion: The proposed physical and occupational therapy program, may be effective for patients with subacute NA, as demonstrated by improvements in activity, performance and participation.

Abstract: Background: Virtual reality games and simulations have been utilized successfully for motor rehabilitation of individuals with traumatic brain injury (TBI). Little is known, however, how TBI-related cognitive decline affects learning of motor tasks in virtual environments. Objective: To fill this gap, we examined learning within a virtual reality game involving various reaching motions in 14 patients with TBI and 15 healthy individuals with different cognitive abilities. Methods: All participants practiced ten 90-second gaming trials to assess various aspects of motor learning. Cognitive abilities were assessed with a battery of tests including measures of memory, executive functioning, …and visuospatial ability. Results: Overall, participants with TBI showed both reduced performance and a slower learning rate in the virtual reality game compared to healthy individuals. Numerous correlations between overall performance and several of the cognitive ability domains were revealed for both the patient and control groups, with the best predictor being overall cognitive ability. Conclusions: The results may provide a starting point for rehabilitation programs regarding which cognitive domains interact with motor learning. Show more
