Effectiveness of a sensor-based technology in upper limb motor recovery in post-acute stroke neurorehabilitation: a randomized controlled trial.

Sensor-based technological therapy devices could be a possible neurorehabilitation strategy for motor rehabilitation in patients with stroke during the post-acute hospitalization, especially for treating upper extremities function limitations. The audio-visual feedback devices are characterized by interactive therapy games that allow training the movement of shoulders, elbows, and wrist, measuring the strength and the active range of motion of upper limb, registering data in an electronic database to quantitatively monitoring measures and therapy progress. This study aimed to investigate the effects of sensor-based motor rehabilitation in add-on to the conventional neurorehabilitation for improving the upper limb functions in patients with subacute stroke. Thirty-seven patients were enrolled in the study and randomly assigned to the experimental group and the control group. The training consisting of twelve sessions of upper limb training compared with twelve sessions of upper limb sensory-motor training, without robotic support. Both rehabilitation programs were performed for 40 minutes three times a week, for 4 weeks, in addition to conventional therapy. All patients were evaluated at the baseline (T0) and after 4 weeks of training (T1). The within-subject analysis showed a statistically significant improvement in both groups in all clinical scales. The analysis of effectiveness revealed that, compared with baseline (T0), the improvement percentage in the Modified Barthel Index was greater in the experimental group than the control group. The use of a sensor-based training with audio-video-feedback could be a useful complementary strategy for improving upper limb motor functions in patients with stroke during post-acute neurorehabilitation.

Sensorized assessment of bilateral hand movements in patients with stroke driven by rhythmic auditory or visual-auditory stimulation.

There is a growing body of literature about the efficacy in neurorehabilitation of the devices providing rhythmic auditory stimulations or visual-auditory stimulations, such as videogames, for guiding the patients' movements. Despite being presented as tools able to motivate patients, their efficacy was not been proven yet, probably due to the limited knowledge about the factors influencing the capability of patients to move the upper limbs following an external stimulus. In this study, we used a marker less system based on two infrared sensors to assess the kinematics of up and down in-phase and anti-phase bilateral hand oscillations synchronized or not with an external stimulus. A group of stroke survivors, one of age-matched healthy subjects and one of young healthy subjects were tested in three conditions: no stimulus, auditory stimulus, and video-auditory stimulus. Our results showed significant negative effects of visual-auditory stimulus in the frequency of movements (p = 0.001), and of auditory stimulus in their fluidity (p = 0.013). These results are conceivably related to the attentional overload required during the execution of bilateral movements driven by an external stimulus. However, a positive effect of external stimulus was found in increasing the range of movements of the less functional hand in all subjects (p = 0.023). These findings highlight as the type of stimulus may play a crucial role in the patient's performance with respect to movements that are not-externally driven.

Effect of different music genres on gait patterns in Parkinson's disease.

The timing and size of repetitive, internally generated, automatic sequences of movements are particularly affected in Parkinson's disease. The most evident consequence of this deficit is the alteration of gait patterns, with a loss of rhythmicity, shorter steps, slower walking, and trunk instability. Several studies have highlighted a potential benefit of listening to music on the normalization of walking patterns. However, most of these studies investigated the effect of a single specific music. We hypothesized that different musical genres may induce different modifications of spatiotemporal parameters and trunk oscillations during walking. In this study, we enrolled healthy young subjects, healthy elderly, and patients with Parkinson's disease. They were asked to walk listening, by a wireless headset, one of six different music tracks (related to four different musical genres) while wearing an inertial measurement unit at pelvis level used to assess their walking patterns. The main effect of music tracks resulted statistically significant in all the gait parameters (p < 0.05), but for symmetry of lower trunk movements. This effect was independent by group. The only significant interaction between music and group, in fact, was found for pelvis obliquity range of motion (p = 0.019). Post hoc analyses showed as classical music reduced speed and trunk tilting (p < 0.01), whereas the range of pelvic obliquity movements in frontal plane were increased by rock, motivational, and heavy metal songs (p < 0.015). In conclusion, the gait patterns were altered by listening music depending by the musical genre, and these adaptations occurred similarly among the three groups, including patients with Parkinson's disease.

Post Soft Care: Italian implementation of a post-stroke checklist software for primary care and identification of unmet needs in community-dwelling patients.

The needs of community-dwelling stroke patients are often not fully addressed. The Global Stroke Community Advisory Panel had developed the Post Stroke Checklist (PSC) with the aim of standardizing long-term stroke assessment and consequently care of patients. PSC has been validated for UK and Singapore, and an Italian version has been proposed. The aim of this study is to assess the needs of community-dwelling Italian stroke patients using an online version of PSC. Secondary aim is to assess utility of PSC for patients and clinicians. The PSC was administered to a sample of 64 patients with stroke in Italy by general practioners. PSC is a questionnaire formed by 11 questions, each one covering a domain identified as important for patients' health. After administration of PSC, patient and clinician satisfaction with the PSC was assessed by a specific questionnaire. The PSC identified specific problems for patients related to a worsening from the last examination not evaluated by any specialist. The online PSC highlighted problems related to mood, (in 50% of sample), mobility (53.1%), spasticity (42.2%), and pain (37.5%). Both patients and clinicians provided good results about the utility of online PSC. The PSC was confirmed to be a useful tool for identifying the needs of community-dwelling patients with stroke. Particular attention should be deserved to problems related to mood, mobility, and hence participation to social life, pain, and spasticity. For taking into account these aspects, the online PSC can be a useful portable tool for clinicians.

Individualized quality of life of severely affected multiple sclerosis patients: practicability and value in comparison with standard inventories.

PURPOSE: Individualized quality of life (QoL) measures differ from traditional inventories in that QoL domains/weights are not predetermined, but identified by the individual. We assessed practicability of the Schedule for the Evaluation of Individual QoL-Direct Weighting (SEIQoL-DW) interview in severely affected multiple sclerosis (MS) patients; the key QoL dimensions identified; and the correlation of the SEIQoL-DW index score with standard patient-reported outcome measures (PROMs). METHODS: Participants were people with severe MS who performed the baseline visit of the PeNSAMI trial (ISRCTN73082124). The SEIQoL-DW was administered at the patient's home by a trained examiner. Patients then received the following PROMs: the Core-Palliative care Outcome Scale (Core-POS), the Palliative care Outcome Scale-Symptoms-MS (POS-S-MS), the European Quality of Life Five Dimensions-3L (EQ-5D-3L), and the Hospital Anxiety and Depression Scale (HADS). RESULTS: Of 59 enrolled patients, 11 (19 %) did not receive the SEIQoL-DW (and the other PROMs) because of severe cognitive compromise or inability to communicate. SEIQoL-DW administration was completed and deemed valid in all 48 cases (mean age 60 years, 58 % women, median Expanded Disability Status Scale score 8.5). Mean SEIQoL-DW index score was 59.1 (SD 25.5). The most commonly nominated SEIQoL-DW areas were family (94 % of the patients), relationships, and leisure activities (both 65 %). Core-POS and POS-S-MS contained 70 % of the SEIQoL-DW-nominated areas. Nevertheless, correlations between SEIQoL-DW index, Core-POS, and POS-S-MS (and the other PROMs) were negligible. CONCLUSIONS: Individualized QoL can be assessed in severely affected MS patients, providing information that is not tracked by the standard inventories Core-POS, POS-S-MS, EQ-5D-3L, and HADS.

The clinical course of vestibular neuritis from the point of view of the ocular vestibular evoked myogenic potential.

BACKGROUND: Studying otolith functions after unilateral vestibular neuritis using ocular vestibular-evoked myogenic potentials and subjective visual vertical tests could give different results. METHOD: A total of 39 patients underwent a vestibular assessment that included the Dizziness Handicap Inventory and horizontal and vertical semicircular canal function testing with video head impulse testing, ocular vestibular-evoked myogenic potential testing, cervical vestibular-evoked myogenic potentials and subjective visual vertical testing. RESULTS: All patients showed a significant alteration (asymmetry ratio more than 40 per cent) for ocular vestibular-evoked myogenic potentials as well as for subjective visual vertical testing (more than -2° to more than +2°) during the acute phase, whereas after 72 hours from the acute vertigo attack normal values (asymmetry ratio less than 40 per cent) were found in 6 out of 39 patients for ocular vestibular-evoked myogenic potentials and 36 out of 39 for the subjective visual vertical (less than -2° to less than +2°). CONCLUSION: Ocular vestibular-evoked myogenic potentials are the most suitable test to evaluate otolith functions in patients with unilateral vestibular neuritis in the acute and sub-acute phase.

Laparoscopic adrenalectomy for a giant adrenal myelolipoma: A case report.

CASE PRESENTATION: We describe a case of a patient who presented with a mildly symptomatic, giant myelolipoma which was excised by laparoscopic approach without complications. INTRODUCTION AND IMPORTANCE: Adrenal myelolipoma (AML) is a rare tumour composed by fat and myeloid tissues. Usually it is asymptomatic, so the diagnosis is mostly incidental. It is generally located in the right adrenal gland, but it can also be found bilaterally. If its size exceeds 10 cm it is defined as a "giant myelolipoma"; in this case its treatment of choice would be adrenalectomy with an open surgical approach. CLINICAL DISCUSSION: Patient's signs and symptoms were mild pain in the right hypochondrium and a positive right Giordano's sign. The mass was detected by a contrast-enhanced CT scan. Once excised it measured 16 cm. CONCLUSION: Laparoscopic adrenalectomy for giant myelolipoma is a safe approach if performed by an expert surgeon, with low risk of bleeding and a better outcome for the patient.

From movement to thought and back: a review on the role of cognitive factors influencing technological neurorehabilitation.

In recent years, cognitive theories have increasingly influenced the approach to motor rehabilitation. The connection between different aspects of cognitive and motor function is increasingly documented, underlining the importance of developing rehabilitation projects that take cognitive aspects into account. The aim of this non-systematic review is to highlight the relationship between cognition and motion and, in the light of new rehabilitation technologies, to better define how aspects of cognition can affect motor rehabilitation.

Development of a patient-centered questionnaire for post-stroke spasticity assessment: a reliability study.

In the emerging scenario of patient-centered medicine, it is becoming increasingly important to involve patients in the management of chronic diseases. The rehabilitation field currently has no assessment tool for evaluating the functional impact of post-stroke spasticity on activities of daily living. The aim of this study was to identify a tool to fill this gap. The "Spasticity Questionnaire in Real Life" (SPQR) was administered, twice, to 39 patients with poststroke spasticity. Statistical analysis showed internal consistency and reliability of the questionnaire, with values greater than 0.96 and 0.76, respectively. These results show that the SPQR is a promising tool for evaluating the functional impact of post-stroke spasticity.

Effects on balance skills and patient compliance of biofeedback training with inertial measurement units and exergaming in subacute stroke: a pilot randomized controlled trial.

Stroke patients have reduced balance and postural control that limits their activities of daily living and participation in social life. Recently, many exergaming systems based on video-biofeedback have been developed for balance training in neurological conditions, however their efficacy remains to be proven. The aim of this study was to investigate the effects on balance skills and patient compliance of biofeedback training based on inertial measurement units and exergaming in subacute stroke. The enrolled subjects were randomized into two groups: subjects allocated to the experimental group performed 10 sessions of biofeedback balance training using inertial sensors, whereas subjects allocated to the control group performed 10 sessions of conventional balance training. All subjects were assessed at T0 (pre-treatment), T1 (posttreatment) and T2 (1-month follow-up). The Berg Balance Scale, Rivermead Mobility Index and modified Barthel Index were used to assess balance, mobility and global disability, respectively. To assess the severity of the stroke and its effects on the patient we used the National Institutes of Health Stroke Scale and the Canadian Neurological Scale. Finally, a static force platform evaluating stabilometric parameters was used to assess balance skills. Fifteen subjects with subacute stroke (4F; age 57.80 ± 13.7) completed the experimental protocol. The analysis showed a significant improvement in balance skills and in the overall clinical outcomes in the experimental group compared with the control group; the experimental group also showed better compliance with the training. The biofeedback system of the device used in this study probably enhances neuroplasticity mechanisms of postural and balance skills in subacute stroke patients.

From paper to informatics: the Post Soft Care-App, an easy-to-use and fast tool to help therapists identify unmet needs in stroke patients.

Even after rehabilitation, post stroke patients remain disabled. The Post Stroke Checklist (PSC) was developed to highlight unmet needs of community-dwelling stroke patients. The present study set out to validate Post Soft Care-App, designed to administer the PSC using smartphones and tablets, in order to monitor unmet needs in chronic patients. Fifty-three patients and fifteen physiotherapists were enrolled. The therapists administered the PSC to patients using the app, and then completed a structured questionnaire on its usability and utility. The Post Soft Care-App highlighted the following unmet needs: increased spasticity (56.6%), reduced independence in activities of daily living (47.2%), reduced mobility (45.3%), absence of secondary prevention (45.3%). Therapists positively evaluated Post Soft Care-App as useful, practical, quick to complete (96.2%), and effective in helping improve communication with patients (75.5%). The Post Soft Care-App can be considered a valid assessment tool for helping therapists to monitor functional outcomes in chronic patients.

Genetic heterogeneity in uveitis.

Eighty-nine unrelated patients with ocular inflammation (uveitis) were investigated for the HLA class I and class II genetic markers, We subdivided our patients according to: 1. the anatomical location of the lesion; 2. the temporal course of the disease; 3. the aetiology. We eliminated from our sample of patients the individuals with other systemic diseases. We could not find an association with B27, as previously described, but we did note statistically significant differences between the class II antigen distribution in the different anatomical subgroups. HLA-DR3 seems a marker of the intermediate form of uveitis (p, uncorrected 0.03); the absence of DR1 in the patient group with posterior uveitis may be a protecting factor (p. uncorrected less than 0.01); the presence of DR4 in all cases of panuveitis is statistically significant (p, uncorrected = 0.0006).

Radioguided surgery for gastrinoma: a case report.

AIMS AND BACKGROUND: Gastrinomas are the most common neuroendocrine tumors of the duodenopancreatic region. Surgical resection is the primary type of radical treatment. METHODS AND STUDY DESIGN: At the Institute of General, Gastrointestinal and Breast Surgery we treated a patient with a duodenal gastrinoma that was diagnosed and localized by means of selective celiac-mesenteric angiography and labelled octreotide scintigraphy. Surgery was performed using a radioguided technique; in this way we easily detected the small tumor and discovered another tracer-uptaking lesion that turned out to be a metastatic lymph node. RESULTS: Surgical resection is the ideal treatment for sporadic gastrinoma: it improves quality of life, prolongs survival, and reduces the incidence of metastases, with a modest percentage of complications and practically zero mortality. Meanwhile, medical treatment is being reevaluated, particularly in the case of metastatic disease or polyendocrine MEN1 syndrome. A fundamental aspect in the management of gastrinomas is tumor localization. Endoscopic ultrasonography and labeled octreotide scintigraphy (Ostreoscan) proved to be more effective than the usual imaging modalities. Intraoperative ultrasonography gastroscopy for duodenal transillumination and repeated measurement of blood gastrin levels should be performed intraoperatively in the surgical treatment of gastrinomas. CONCLUSIONS: The clinical application of radioguided surgery for tracer-uptaking endocrine tumors is still controversial. In our case the decision to use this method was influenced by the fear that the patient's obesity and the effects of previous surgery could hamper the identification of the small tumor.

[Angiomorphology of the ciliary body in diabetic disease]. / Angiomorphologie du corps ciliaire dans la maladie diabétique.

The authors describe the pathological changes in the vascular structures of the ciliary body occuring in diabetes mellitus. The lesions consist of a quantitative reduction in the number of vessels and in modifications of diameter and arborisation. Changes include sectoral thinning, isolated and grouped aneuryms and marked tortuosity. These findings are thought to be constant in the diabetic patient and are probably involved in the various aspects of diabetic eye disease affecting other structures besides the ciliary body. The group of vascular changes in the ciliary body in diabetes may aptly be termed "diabetic ciliopathy".

[Surgical treatment of pulmonary metastases of sarcoma]. / Trattamento chirurgico delle metastasi polmonari di sarcomi.

Lungs are the most common target of metastases from osteogenic and soft tissue sarcomas. Metastases can be successfully treated by surgery. Only a few patients with non treated pulmonary metastases from sarcomas are alive after 5 years. In fact, without surgery the 1-year mortality is 50%. The number of metastases, the site in one or both lungs, the disease-free period and the tumoral doubling time have important prognostic significance. The authors report two interesting cases successfully treated with surgical therapy.

[Surgical treatment of pulmonary metastases of primary neoplasms of the urogenital tract]. / Considerazioni sul trattamento chirurgico delle metastasi polmonari di neoplasie primitive dell'apparato uro-genitale.

The authors review the literature data concerning the surgical therapy of pulmonary metastases from genital and urinary tumours. In both cases a combined chemo-surgical treatment is able to increase longterm survival. Some personal cases successfully treated are reported. The case is reported also of a young girl operated on for pulmonary metastases from a Wilms tumour. Successively, a heart transplantation was performed. She is alive and well.

[Surgical treatment of pulmonary metastases in colorectal carcinoma]. / Trattamento chirurgico delle metastasi polmonari di carcinoma del colon-retto.

After surgical exeresis of pulmonary metastases from colorectal carcinoma the 5-year survival rate is 30% vs 5% in non treated patients. Postoperative survival is longer for patients with a primary rectal cancer. Single pulmonary metastatic lesions, negative ilar and mediastinal lymph nodes, and Dukes' stages A and B are favourable prognostic criteria. The authors review literature's data and report and analyze their clinical observations.

[Primary and secondary pulmonary tumors associated with head and neck carcinoma]. / Tumori polmonari primitivi e secondari in associazione con carcinomi della testa e del collo.

The authors analyze personal and literature results in surgery of primary and secondary lung cancer associated with head and neck malignancies. Eighteen patients with primary lung cancer associated with head and neck cancer were compared with six patients affected by pulmonary metastases from head and neck cancer. In the first group the 3-year postoperative survival rate was 60.5%, in the second group 33%. Differential diagnosis between primary and metastatic lung tumours may be easy when multiple pulmonary nodes are present. When only one pulmonary node is present, diagnosis is more difficult. Thoracotomy is necessary to perform the correct diagnosis and the best postoperative medical treatment.

[The surgery of lung metastases of melanoma]. / La chirurgia delle metastasi polmonari di melanoma.

Melanoma is considered one of the most lethal cancers and surgical therapy of its pulmonary metastases is rarely indicated. The only hope for a successful surgical treatment of secondaries from melanoma is a radical resection. Considering the very frequent multiorgan involvement of melanoma metastases, surgery is usually possible in less than 5% of cases. Nevertheless, in selected cases without lymph nodal involvement a 5-year survival rate of 31% has been reported. In any way, it must be remembered that about 10% of lung tumours thought to be metastases are primary cancers. In this occurrence surgery could be a rescuing solution. So, a pulmonary resection is always imperative when some diagnostic doubt exists.
