RESUMO
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.

Sense of time is a complex construct, and its neural correlates remain to date in most part unknown. To complicate the frame, physical attributes of the stimulus, such as its intensity or movement, influence temporal perception. Although previous studies have shown that time perception can be compromised after a brain lesion, the evidence on the role of the left and right hemispheres are meager. In two experiments, the study explores the ability of temporal estimation of multi-second actions and non-biological movements in 33 patients suffering from unilateral brain lesion. Furthermore, the modulatory role of induced embodiment processes is investigated. The results reveal a joint contribution of the two hemispheres depending not only on different durations but also on the presence of actions. Indeed, the left hemisphere damaged patients find it difficult to estimate 4500 ms or longer durations, while the right hemisphere damaged patients fail in 3000 ms durations. Furthermore, the former fail when a biological action is shown, while the latter fail in non-biological movement. Embodiment processes have a modulatory effect only after right hemisphere lesions. Among neuropsychological variables, only spatial neglect influences estimation of non-biological movement.

BACKGROUND: Functional neuroimaging studies show adaptive changes in areas adjacent and distant from the stroke. This longitudinal study assessed whether changes in cortical excitability in affected and unaffected motor areas after acute stroke correlates with functional and motor recovery. METHODS: We studied 13 patients with moderate to severe hemiparesis 5 to 7 days (T1), 30 days (T2), and 90 days (T3) after acute unilateral stroke, as well as 10 healthy controls. We used paired-pulse transcranial magnetic stimulation to study intracortical inhibition and facilitation, recording from the bilateral thenar eminences. F waves were also recorded. RESULTS: At T1, all patients showed significantly reduced intracortical inhibition in the unaffected hemisphere. At T2, in patients whose motor function recovered, intracortical inhibition in the unaffected hemisphere returned to normal. In patients with poor clinical motor recovery, abnormal disinhibition persisted in both hemispheres. At T3, in patients whose motor function progressively recovered, the abnormal disinhibition in the unaffected hemisphere decreased further, whereas in patients whose motor function remained poor, abnormal inhibition in the unaffected hemisphere persisted. No modification of F-wave latency and amplitude were found in patients and controls. CONCLUSIONS: During early days after stroke, motor cortical disinhibition involves both cerebral hemispheres. Longitudinal changes in motor disinhibition of the unaffected hemisphere may reflect the degree of clinical motor recovery.

AIMS: To study the association of pain with motor complications in 117 patients with Parkinson's disease. METHODS: Patients were asked to refer any pain they experienced at the time of study and lasting since at least 2 months. Basic parkinsonian signs and motor complications (including motor fluctuations and dyskinesia) were assessed and Unified Parkinson's Disease Rating Scale (UPDRS) motor score part III (during on) and part IV were calculated. Information on age, sex, duration of disease, use of dopamine agonists and levodopa, years of levodopa treatment and current levodopa dosage, medical conditions possibly associated with pain, and depression were collected. Single and multiple explanatory variable logistic regression models were used to check the association of pain with the investigated variables. RESULTS: Pain was described by 47 patients (40%) and could be classified into dystonic (n.19) and non dystonic pain (n.16); in 12 patients both types coexisted. Multiple explanatory variable logistic regression models indicated a significant association of pain with motor complications (adjusted OR, 5.7; 95% CI, 2 to 16.5; p = 0.001). No association was found between pain, dystonic or non dystonic, and the other investigated variables including medical conditions known to be associated to pain in the general population. There was a significant correlation (r = 0.31, p<0.05) between severity of pain (measured on a Visual Analogue Scale) and severity of motor complications (UPDRS part IV). CONCLUSIONS: Pain may be a representative feature of Parkinson's disease frequently associated with motor complications. The association is independent of a number of potentially relevant demographic and clinical variables.

The aim of this study was to evaluate the short, medium and long-term effects of peripheral repetitive magnetic stimulation (rMS) on myofascial pain compared with transcutaneous electrical nerve stimulation (TENS).Fifty-three subjects with myofascial trigger points (TPs) at the level of the superior trapezius muscle were allocated randomly to three groups. The first group (n=17) was treated with rMS, the second (n=18) with TENS and the third (n=18) received a placebo treatment. Each treatment consisted of ten daily 20-minute sessions. Patients were evaluated before and immediately following treatment, and at one and three months after the end of treatment. Outcome measures were: the "neck pain and disability visual analogue scale" (NPDVAS), an algometric evaluation of pain, an evaluation of the TP characteristics, and the range of cervical bending and rotation contralateral to the affected trapezius muscle. At the end of treatment, the rMS group showed a significant improvement in the NPDVAS, algometry, TP characteristics, and cervical contralateral rotation. This improvement also persisted at one and three months post-therapy. After treatment, the TENS group showed significant improvement in the same outcome measures except for algometry. At the one month follow-up visit, this improvement had returned to non significant levels in all outcome measures with the exception of NPDVAS. No significant effect of TENS was seen at the three-month follow-up visit. The placebo group showed no significant improvement in any measure. Our results strongly suggest that at medium and longer term intervals peripheral rMS may be more effective than TENS for the treatment of myofascial pain.

Gait disorders are common and very disabling in elderly people, leading to an increase of risk of falling and reductions in quality of life. So far, many clinical classifications of gait disorders in the elderly population have been proposed. Here we suggest a novel categorization of gait disorders in elderly people, which takes into account the several resources required during gait. The biomechanical constraints, movement and sensory strategies, orientation in space, control of dynamics and cognitive processing are essential to perform safely gait. Moreover, the strictly connection between gait and balance has been discussed. According to this perspective, a literature search was performed including studies investigating the rehabilitation procedures in the management of balance and gait disorders in elderly people. Training aimed at improving muscle strength and flexibility, movement strategies, sensorimotor integration and sensory reweighting processes, balance in static and dynamic conditions and cognitive strategies have been proposed as possible therapeutic approaches in elderly people affected by gait disorders. Moreover, the role of new technological devices in improving balance and gait control has been also described. A multidisciplinary and interdisciplinary approach is fundamental for the management of gait disorders in elderly people. Rehabilitation procedures should take into consideration all the potential constraints involved in gait disorders in order to select the most appropriate intervention.
RESUMO
We instructed patients with right brain damage (RBD) and somatosensory extinction, hemispatial neglect, or both to verbally report light touches delivered to the left hand, to the right hand, or simultaneously to both hands in two experimental situations. In the "anatomic" situation, each hand was in its homonymous hemispace; in the "crossed" one, each hand was held across the corporeal midline, in its heteronymous hemispace. Under both single and the double stimulation conditions, RBD patients detected stimuli delivered to the contralesional hand with lower accuracy in the anatomic than in the crossed position. This result suggests that somaesthetic deficits can be due not only to sensory but also to attentional factors, depending on the spatial position of the hands. Processing of sensory information in primary areas should not be influenced by the hemispatial position of the stimulated body part. These results suggest that somaesthetic deficits may stem not only from damage of primary sensory areas, as classically held, but also from damage of higher-order areas where information about stimuli, body parts, and extrapersonal space is integrated. Finally, the results show that sensory and attentional components of the deficit can be dissociated by using a very simple clinical test.

We delivered unilateral (left or right) or bilateral tactile stimuli to hands or feet of right-brain-damaged patients, six with tactile extinction and two without. Stimuli were simple touches or sliding stimuli directed proximo-distally (e.g., toward the fingers) or disto-proximally (e.g., toward the forearm). Patients were asked to report number (one or two), type (touch or slide), and direction (proximo-distally or disto-proximally) of the experimental stimuli. Nonextinction patients performed perfectly. Extinction patients, although accurate in reporting single stimuli, omitted left stimuli under double-stimuli conditions. However, the number of left stimuli detected consciously was related to an imbalance of the salience between left and right stimuli. Moreover, in three patients the extinguished, left-sided stimulus, even when inaccessible to consciousness, influenced implicitly the report of the features of the right stimulus. Thus, the relationships between left and right stimuli can modulate both overtly and covertly the performance of extinction patients.

Patients with left visual extinction as a result of unilateral right hemisphere damage were tested on a redundant-targets effect paradigm (RTE). LED-generated brief flashes were lateralized either to the left or to the right visual hemifield or presented bilaterally. Subjects were asked to press a key as fast as possible following either unilateral or bilateral stimuli and immediately afterwards to report on the number of stimuli presented. As previously found in normal subjects, bilateral stimuli were responded to faster than unilateral ones, and this was evidence of a RTE. The main thrust of this study was that extinction patients showed a RTE not only for correctly perceived bilateral stimuli but also in trials in which they extinguished the stimulus on the field contralateral to the lesion. This result is compatible with a preserved processing of the extinguished input at least up to the stage at which it may interact with the input from the normal side to yield a speeded motor response. Interestingly, the implicit redundancy gain of extinction patients was found to fit a coactivation (i.e. neural) rather than a probabilistic model.

In a left index finger amputee, appropriate stimulation of skin areas of the remnant left fingers or left lower face evoked veridical sensations as well as sensations localized to the phantom finger. Five months after the amputation, there was a systematic correspondence between positions of digital and facial stimuli and positions of stimuli felt on the phantom. More than 3 years after the amputation, orderly maps of the phantom index on the ipsilateral fingers were still detected. By contrast, poorly organized facial maps were present only contralaterally to the amputation. The maps on the remnant fingers are likely to acquire stability because they are systematically activated during manipulations performed with the mutilated hand. The disorganization of facial maps may be related to their irrelevance for behavioral control in everyday life conditions.

We describe a patient who in 1983 suffered a stroke which resulted in severe hemiplegia and somatosensory loss. His neurological condition remained stable until January 1996, when, because of a myocardial infarction, the patient underwent systemic thrombolytic therapy which led to a remarkable improvement of both motor and somatosensory functions. This finding suggests the existence of 'idling neurons' which remain viable for a long time after stroke, and opens a fascinating window on the therapeutic potential of thrombolytic therapy in chronic stroke patients.

We describe a woman with right brain damage who denied the ownership of her left hand and of extracorporeal objects (e.g. rings) which were worn on the left hand itself. When the same objects were worn on the right hand or were held by the examiner, the patient correctly recognized them as her own. Other personal objects unrelated to the left hand (e.g. pins, earrings, comb) were always correctly recognized as her own. Thus, by inference, the mental image of one's body may include inanimate objects which had been in contact or in close proximity with the body itself. These findings provide, for the first time, experimental support to the speculative notion of an extended body schema.

OBJECTIVES: To investigate motor disinhibition in affected and unaffected motor areas in the acute stage after stroke and during the early period of recovery. METHODS: Fifteen patients with moderate to severe hemiparesis after acute unilateral stroke were compared with 10 healthy age-matched controls. We used paired transcranial magnetic stimulation to study intracortical inhibition and facilitation from the thenar eminence muscles on both sides. F-wave from the median nerve on both sides were recorded. The recordings were performed 5-7 days (T1) and 30 days after stroke. RESULTS: In 10 patients who showed the presence of reliable motor evoked potentials on the affected side, intracortical inhibition was significantly reduced. On the unaffected side intracortical inhibition (ICI) was significantly reduced in all patients. Patients who presented significant motor recovery after 30 days showed persistence of abnormal disinhibition in the affected hemisphere but a return to normal ICI in the unaffected hemisphere. Patients with poor motor recovery showed persistence of abnormal disinhibition on both sides. No significant changes were observed in F-wave amplitude. CONCLUSIONS: Motor disinhibition occurs on both sides after stroke in all acute stage patients. Changes in motor disinhibition on unaffected side also are related to motor recovery.

We have studied a patient, CZ, with contralateral visual extinction due to a large ischaemic frontal-parietal-temporal lesion in the right hemisphere. We found that manipulation of intensity of the visual stimulus had little effect while an increase in eccentricity substantially increased extinction rate. An important factor was represented by the hemifield of stimulus presentation: when double stimuli were presented to the contralesional (left) hemifield, the leftmost stimulus was consistently extinguished while when stimuli were presented to the ipsilesional (right) hemifield, extinction was absent. Such effect was specific to hemifield rather than to head- and trunk-defined hemispace. Manipulation of response-related variables affected extinction to a large extent: In particular, the use of nonverbal responses diminished extinction considerably. This suggests that an important component of extinction may be represented by an impaired access of visual information to the left hemisphere. Finally, the RT results confirmed previous evidence of an ipsilesional attentional bias favouring the rightmost stimuli both in the contralesional and in the ipsilesional hemifield.

AIM: The aim of this study was to evaluate the effectiveness of early or delayed orthotic treatment of congenital metatarsus varus and evaluate the efficacy of static vs dynamic anti-varus orthosis. METHODS: Twenty-five children (14 males, 11 females), of 81.3 days of age (range 1-189) (41 feet affected) were selected among 88 patients referred to our rehabilitation department for foot deformity. Children were assigned to 1 of 2 groups (dynamic or static orthosis) according to a simple randomization scheme. Patients were evaluated at diagnosis (T1), at the end of treatment (T2) and at a follow-up performed at least 2 years after the end of treatment (T3). Primary outcome was measured using the Bleck scale. The IOWA functional rating system questionnaire was performed at follow up evaluation. RESULTS: The Bleck scale showed that both static and dynamic orthoses were effective and that the best results were achieved with early treatment. The IOWA questionnaire showed that no child had residual deformities that interfered with daily activities. Nonetheless, the dynamic orthosis group had better scores in 4 sub-items related to parental satisfaction, foot function, heel position, and foot passive motion. CONCLUSIONS: Both static and dynamic orthoses are useful for correction of congenital metatarsus varus. Optimal results are achieved with early treatment.
RESUMO
AIM: Myofascial pain syndrome (MPS) is a frequent cause of chronic muscoloskeletal pain. Transcutaneous electrical nerve stimulation (TENS) is one of the most frequently employed treatments in MPS. The aim of this study is to compare the short and medium-term effects of frequency modulated neural stimulation (FREMS) to those of TENS in MPS. METHODS: Forty subjects with upper trapezius MPS were randomly allocated to 1 of 2 groups, treated with either FREMS (n=19) or TENS (n=21). Each treatment consisted in 10 sessions lasting 20 min each. Patients were evaluated before treatment, at 1 week, and at 1 and 3 months after the end of treatment. Clinical evaluation included parameters for measurement of pain levels using the neck pain and disability visual analogue scale (NPDVAS) and algometry, evaluation of myofascial trigger point characteristics and measurement of the range of cervical movement (range of motion, ROM). RESULTS: The FREMS group showed a significant improvement in the NPDVAS, algometry, in myofascial trigger point characteristics, and in the ROM (homolateral rotation, controlateral rotation, bending and extension) after the end of treatment and at 1 and 3 months follow-up evaluation. The TENS group showed significant improvement in the same outcome measures except for algometry and cervical extension, but these improvements were maintained only at the 1 month follow-up evaluation. However, were not observed statistically significant differences between FREMS of TENS in many of outcome measures. CONCLUSIONS: Both FREMS and TENS have positive short-term effects on MPS. But, medium-term effects were achieved only with FREMS.
RESUMO
BACKGROUND: Spasticity is a common disabling symptom of several neurological conditions including stroke. Botulinum toxin type A (BTX-A) injection represents the gold standard therapy for focal spasticity. Post-stroke management of patients receiving BTX-A therapy has been variously investigated, but general agreement on how and when to implement rehabilitation is lacking. AIM: To perform a national survey of experts on the most appropriate rehabilitation procedures after BTX-A therapy for the focal treatment of spasticity. DESIGN: The study employed the Delphi technique through the COSMO project (Consensus on Post-Injection Management in Post-stroke Spasticity). METHODS: Italian neurologists and physiatrists with experience in BTX-A therapy were selected to participate in the survey. Their anonymous opinions on key issues in treatment strategies in post-stroke spasticity were collected in three sequential rounds facilitated by a web platform. Consensus on a given issue was defined as agreed opinion by at least 66% of the survey participants. RESULTS: In all, 44 Italian experts were involved. Positive consensus was reached on the need to start rehabilitation during the first week after BTX-A injection therapy, with a rehabilitation program comprising both stretching combined with electrical stimulation and exercise therapy. Functional surgery may be considered only after 12-24 months in cases of BTX-A therapy failure. The use of commercial or custom-made orthoses in selected cases was recommended. The appropriate time interval between two BTX-A injections is 3-6 months, and clinical assessment should be performed 1 month after injection. CONCLUSION: The results of this national survey confirm that clinical experts on the use of BTX-A therapy for spasticity after stroke agree on the need to initiate rehabilitation treatment immediately after BTX-A injection: muscle stretching exercises, eventually combined with neuromuscular electrical stimulation, may enhance the effect of BTX-A therapy. Outcome after BTX-A therapy should be assessed at repeated follow-up visits. CLINICAL REHABILITATION IMPACT: This expert panel survey can provide guidance for clinicians in the assessment of patients treated with BTX-A therapy.

BACKGROUND: The degree of initial paresis relates to spasticity development in stroke patients. However, the importance of proximal and distal paresis in predicting spasticity after stroke is unclear. AIM: To investigate the role of topical distribution of initial limb paresis to predict clinically relevant spasticity in adults with stroke. DESIGN: Retrospective cohort study METHODS: Seventy-two first-ever ischemic stroke patients were examined. At the acute phase of illness, demographics and the European Stroke Scale motor items (maintenance of outstretched arm position, arm raising, wrist extension, grip strength, maintenance of outstretched leg position, leg flexion, foot dorsiflexion) were evaluated. At six months after the stroke onset, spasticity was assessed at the upper and lower limb with the modified Ashworth Scale. Clinically relevant spasticity was defined as modified Ashworth Scale ≥3 (0-5). RESULTS: The degree of initial paresis of the proximal muscles of the upper limb and the distal muscles of the lower limb showed the strongest association and the best profile of sensitivity-specificity in predicting clinically relevant spasticity at the upper and lower limb, respectively. Younger age showed higher risk for developing clinically relevant spasticity in the upper limb. CONCLUSIONS: Our findings support the hypothesis that the initial degree of proximal paresis of the upper limb and distal paresis of the lower limb as well as age may be considered early predictors of clinically relevant spasticity in adults with ischemic stroke. CLINICAL REHABILITATION IMPACT: Our findings further improve the role of initial paresis as predictor of spasticity after stroke.

BACKGROUND: It has been well established that the presence of neglect is a predictor of poor functional outcome after stroke. Most rehabilitation studies on neglect have been performed with at least two months post-stroke. However, a recent series of stroke management indications highlight the importance of early rehabilitation treatment and evidence regarding neglect rehabilitation in the early phase after stroke is needed. AIM: To evaluate the effectiveness of right half-field patches in treating neglect in patients during the early phase of stroke. DESIGN: Randomized controlled trial. SETTING: Acute care setting in an urban general hospital. POPULATION: Eighteen patients with left unilateral neglect recruited among 56 patients consecutively admitted with right hemispheric stroke. METHODS: The patients were evaluated at pre-treatment, post-treatment, and at a 7-day follow-up. The experimental group received right half-field patch treatment (n=10) for approximately 8 hours a day for 15 consecutive days. The control group received visual scanning training (n=8) for 40 minutes every weekday in a 15 day period. RESULTS: Both groups significantly improved their performance in all outcome measures. No difference in the amount of improvement between the two groups was found. CONCLUSION: Right half-field eye patching could be a promising technique for treating visual spatial neglect during the early stages of stroke. CLINICAL REHABILITATION IMPACT: The eye-patching technique may represent an easily applicable and inexpensive method for neglect rehabilitation in the early stage after stroke.
