The effectiveness of reinforced feedback in virtual environment in the first 12 months after stroke
No full textBackground and purpose: Reinforced feedback in virtual environment (RFVE) therapy is emerging as an innovative
method in rehabilitation, which may be advantageous in the treatment of the affected arm after stroke. The purpose of this study was to investigate the impact of assisted motor training in a virtual environment for the treatment of the upper extremity (UE) after stroke compared to traditional neuromotor rehabilitation (TNR), studying also if differences exist related to the type of stroke (haemorrhagic or ischaemic). Material and methods: Eighty patients affected by a stroke (48 ischaemic and 32 haemorrhagic) that occurred at least 1 year before were enrolled. The clinical assessment comprising the Fugl-Meyer UE (F-M UE), modified Ashworth (Bohannon & Smith) and Functional Independence Measure scale (FIM) was administered before and after the treatment. Results: A statistically significant difference between RFVE and TNR groups (Mann-Whitney U-test) was observed in the clinical outcomes of F-M UE and FIM (both p < 0.001), but not Ashworth (p = 0.053). The outcomes of F-M UE
and FIM improved in the RFVE haemorrhagic group and in the TNR haemorrhagic group with a significant difference between groups (both p < 0.001), but not for Ashworth (p = 0.651). Comparing the RFVE ischaemic group to the TNR ischaemic group, statistically significant differences emerged in F-M UE (p < 0.001), FIM (p < 0.001), and Ashworth (p = 0.036). Conclusions: The RFVE therapy in combination with TNR showed better improvements compared to the TNR treatment only. The RFVE therapy combined with the TNR treatment was more effective than the TNR double training, in both postischaemic and post-haemorrhagic groups. We observed improvements in both groups of patients: post-haemorrhagic and post-ischaemic stroke after RFVE training
The effect of robot therapy assisted by surface EMG on hand recovery in post-stroke patients. A pilot study
No full textBackground: Hemiparesis caused by a stroke negatively limits a patient's motor function. Nowadays, innovative technologies such as robots are commonly used in upper limb rehabilitation. The main goal of robot-aided therapy is to provide a maximum number of stimuli in order to stimulate brain neuroplasticity. Treatment applied in this study via the AMADEO robot aimed to improve finger flexion and extension. Aim: To assess the effect of rehabilitation assisted by a robot and enhanced by surface EMG. Research project: Before-after study design. Materials and methods: The study group consisted of 10 post-stroke patients enrolled for therapy with the AMADEO robot for at least 15 sessions. At the beginning and at the end of treatment, the following tests were used for clinical assessment: Fugl-Meyer scale, Box and Block test and Nine Hole Peg test. In the present study, we used surface electromyography (sEMG) to maintain optimal kinematics of hand motion. Whereas sensorial feedback, provided by the robot, was vital in obtaining closed-loop control. Thus, muscle contraction was transmitted to the amplifier through sEMG, activating the mechanism of the robot. Consequentially, sensorial feedback was provided to the patient. Results: Statistically significant improvement of upper limb function was observed in: Fugl-Meyer (p = 0.38) and Box and Block (p = 0.27). The Nine Hole Peg Test did not show statistically significant changes in motor skills of the hand. However, the functional improvement was observed at the level of 6% in the Fugl-Meyer, 15% in the Box and Block, and 2% in the Nine Hole Peg test. Conclusions: Results showed improvement in hand grasp and overall function of the upper limb. Due to sEMG, it was possible to implement robot therapy in the treatment of patients with severe hand impairment
Reinforced Feedback in Virtual Environment for Rehabilitation of Upper Extremity Dysfunction after Stroke: Preliminary Data from a Randomized Controlled Trial
No full textObjectives. To study whether the reinforced feedback in virtual environment (RFVE) is more effective than traditional rehabilitation (TR) for the treatment of upper limb motor function after stroke, regardless of stroke etiology (i.e., ischemic, hemorrhagic). Design. Randomized controlled trial. Participants. Forty-four patients affected by stroke. Intervention. The patients were randomized into two groups: RFVE (N = 23) and TR (N = 21), and stratified according to stroke etiology. The RFVE treatment consisted of multidirectional exercises providing augmented feedback provided by virtual reality, while in the TR treatment the same exercises were provided without augmented feedbacks. Outcome Measures. Fugl-Meyer upper extremity scale (F-M UE), Functional Independence Measure scale (FIM), and kinematics parameters (speed, time, and peak). Results. The F-M UE (P = 0.030), FIM (P = 0.021), time (P = 0.008), and peak (P = 0.018), were significantly higher in the RFVE group after treatment, but not speed (P = 0.140). The patients affected by hemorrhagic stroke significantly improved FIM (P = 0.031), time (P = 0.011), and peak (P = 0.020) after treatment, whereas the patients affected by ischemic stroke improved significantly only speed (P = 0.005) when treated by RFVE. Conclusion. These results indicated that some poststroke patients may benefit from RFVE program for the recovery of upper limb motor function. This trial is registered with NCT01955291
Proprioceptive Based Training for stroke recovery. Proposal of new treatment modality for rehabilitation of upper limb in neurological diseases
No full textThe central nervous system (CNS) has plastic properties allowing its adaptation through development. These properties are still maintained in the adult age and potentially activated in case of brain lesion. In the present study authors hypothesized that a significant recovery of voluntary muscle contraction in post stroke patients experiencing severe upper limb paresis can be obtained, when proprioceptive based stimulations are provided. Proprioceptive based training (PBT) is based on performing concurrent movements with both unaffected and affected arm, with the aim to foster motor recovery through some mutual connections of interhemispheric and transcallosal pathways. The aim of this pre-post pilot study was to evaluate the feasibility of PBT on recovery of voluntary muscle contraction in subacute phase after stroke
Effects of vibratory stimulation on balance and gait in Parkinson’s disease: A systematic review and meta-analysis
No full textINTRODUCTION: Among the different rehabilitative approaches to Parkinson’s disease, there is conflicting evidence about the effects of vibratory stimulation and its capability to modulate the central elaboration of proprioceptive stimuli. the hypothesis is that the vibration-induced sensorial perturbation (through whole body vibration [WBV] or localized vibration) can influence the motor response in complex tasks such as postural control and gait. thus, the objective of this review was to evaluate the effect of different modalities of vibratory stimulation treatment on balance, gait signs and symptoms, and quality of life, in patients with parkinson’s disease. EVidEncE acQuisition: from the initial 1249 records, 10 of them which compared Whole body Vibration (WbV) or localized vibration to conventional physiotherapy were included (i.e. randomized controlled trials, crossover trials, and quasi-experimental trials). Finally, five papers on WbV were included in quantitative synthesis (meta-analysis), while for three studies on localized vibrations a qualitative synthesis was performed. Two independent reviewers selected potentially relevant studies based on the inclusion criteria, extracted data, and evaluated the methodological quality. EVIDENCE SYNTHESIS: Meta-analysis was performed among five studies on WBV treatment, whose effect was found to be significantly better than standard treatment for improving gait (measured by timed up and Go test and stand-walk-sit test: standardized mean difference = -0.51; 95% CI=-1.00 to -0.01). Conversely, WBV was not significantly better than standard treatment for all the other outcomes. Due to high heterogeneity it was not possible to conduct a quantitative meta-analysis on studies of localized vibration. conclusions: results of the review show that WbV can improve gait performance in patients with parkinson’s disease
Virtual Feedback for Arm Motor Function Rehabilitation after Stroke: A Randomized Controlled Trial
No full textA single-blind randomized controlled trial was conducted to compare whether the con-tinuous visualization of a virtual teacher, during virtual reality rehabilitation, is more effective than the same treatment provided without a virtual teacher visualization, for the recovery of arm motor function after stroke. Teacher and no-teacher groups received the same amount of virtual reality therapy (i.e., 1 h/d, 5 dd/w, 4 ww) and an additional hour of conventional therapy. In the teacher group, specific feedback (“virtual-teacher”) showing the correct kinematic to be emulated by the patient was always displayed online during exercises. In the no-teacher group patients performed the same exer-cises, without the virtual-teacher assistance. The primary outcome measure was Fugl-Meyer Upper Extremity after treatment. 124 patients were enrolled and randomized, 62 per group. No differences were observed between the groups, but the same number of patients (χ2 = 0.29, p = 0.59) responded to experimental and control interventions in each group. The results confirm that the manipulation of a single instant feedback does not provide clinical advantages over multimodal feedback for arm rehabilitation after stroke, but combining 40 h conventional therapy and virtual reality provides large effect of intervention (i.e., Cohen’s d 1.14 and 0.92 for the two groups, respectively)
Assessment of the cervical spine mobility by immersive and non-immersive virtual reality
No full textIntroduction: Despite many devices are helpful for motion analysis, there is still no established standard technique for the assessment of cervical spine mobility. Objective: To compare differences in using immersive or non-immersive virtual reality (VR) for the assessment of the sensorimotor movement of the cervical spine in healthy subjects. Methods: Thirty-five healthy adults were asked to perform head rotation, flexion, extension, lateral flexion, reaching and repositioning tasks with the head. The same tasks were performed interacting with both non-immersive and immersive virtual reality. Random sequence determined which of the environments was used as first assessment. Range of motion and kinematics i.e. number of completed targets, time of execution (seconds), spatial length (cm), angle distance (°), jerk of the cervical spine, were automatically computed by a 6D electromagnetic motion tracking system. Results: The following variables were significantly larger in immersive than non-immersive VR: head right rotation (p = 0.027), extension (p = 0.047), flexion (p = 0.000), time (p = 0.001), spatial length (p = 0.004), jerk target (p = 0.032), trajectory repositioning (p = 0.003), jerk target repositioning (p = 0.007). A regression model showed that assessment in both VR environments can be influenced by dependent and independent variables. Conclusions: Immersive VR provided more accurate measurement of cervical spine than non-immersive VR in healthy adults
