To compare the therapeutic effects between acupuncture and electric stimulation on post-stroke dysphagia on the basis of rehabilitation training.
                Ninety-seven patients with post-stroke dysphagia were randomly divided into an acupuncture group (group A, n = 32), an electric stimulation group (group B, n = 35) and a rehabilitation training group (group C, n = 30). In group C, the conventional therapy (conventional therapy of neurologic internal medicine and rehabilitation training) was applied. In group A, the combination of conventional therapy and acupuncture was applied. The acupoints of Fengchi (GB 20), Futu (LI 18), three-needles on the forehead, etc. were selected. In group B, the combination of conventional therapy and electric stimulation was adopted. Watian drinking water experiment, stethocatharsis function scoring and video fluoroscopic swallowing study (VFSS) were used to evaluate swallowing function of patients.
                After treatment, the total effective rate was 96.95 (31/32) in group A and was 94.3% (33/35) in group B, which was superior to that of 66.7% (20/30) in group C (P < 0.01). After treatment, the swallowing function in group A, group B and group C were all improved significantly as compared with that before treatment (all P < 0.05). After treatment, the effects in group A and B were superior to that in group C (both P < 0.05).
                The therapeutic effect of the combination of either acupuncture or electric stimulation with rehabilitation training is better than that of simple rehabilitation training. The efficacy on dysphagia is equal between acupuncture and electric stimulation. To test whether supplementary antioxidants and n-3 fatty acids, alone or in combination, could improve functional status in stroke survivors.
                We performed a randomized, double-blind, placebo-controlled clinical trial in 72 stroke patients (47 males; age 65.3 +/- 12.9 years) admitted to a rehabilitation hospital for sequelae of first-ever ischemic stroke, and divided them into 4 subgroups. Group 1 patients received daily oral antioxidants, group 2 received n-3 polyunsaturated fatty acids, group 3 both supplements, and group 4 placebo, all for 12 months. No difference at baseline was observed among groups in neurological severity or in disability. All measures were repeated after 6 and 12 months of treatment. All major clinical events were recorded.
                At baseline, 25% of the patients had a low plasma vitamin status, and 48.5% was at risk of undernutrition. At the 1-year follow-up, we observed a trend for lower mortality (p = 0.060) in subgroups treated with n-3 fatty acids, but without significant differences in rehabilitation result status among groups.
                Malnutrition is widely observed in patients admitted to a rehabilitative hospital for stroke rehabilitation, and dietary supplementation, even if not able to improve rehabilitation results, is likely to reduce mortality at the 1-year follow-up.
                Copyright 2009 S. Karger AG, Basel. Undernutrition is common in patients admitted with stroke. We aimed to establish whether the timing and route of enteral tube feeding after stroke affected patients' outcomes at 6 months.
                The FOOD trials consist of three pragmatic multicentre randomised controlled trials, two of which included dysphagic stroke patients. In one trial, patients enrolled within 7 days of admission were randomly allocated to early enteral tube feeding or no tube feeding for more than 7 days (early versus avoid). In the other, patients were allocated percutaneous endoscopic gastrostomy (PEG) or nasogastric feeding. The primary outcome was death or poor outcome at 6 months. Analysis was by intention to treat.
                Between Nov 1, 1996, and July 31, 2003, 859 patients were enrolled by 83 hospitals in 15 countries into the early versus avoid trial. Early tube feeding was associated with an absolute reduction in risk of death of 5.8% (95% CI -0.8 to 12.5, p=0.09) and a reduction in death or poor outcome of 1.2% (-4.2 to 6.6, p=0.7). In the PEG versus nasogastric tube trial, 321 patients were enrolled by 47 hospitals in 11 countries. PEG feeding was associated with an absolute increase in risk of death of 1.0% (-10.0 to 11.9, p=0.9) and an increased risk of death or poor outcome of 7.8% (0.0 to 15.5, p=0.05).
                Early tube feeding might reduce case fatality, but at the expense of increasing the proportion surviving with poor outcome. Our data do not support a policy of early initiation of PEG feeding in dysphagic stroke patients. Undernutrition is common in hospital patients with stroke, can develop or worsen in hospital, and is associated with poor outcomes. We aimed to establish whether routine oral nutritional supplements improve outcome after stroke.
                The FOOD trials are a family of three pragmatic, multicentre, randomised controlled trials. We measured the outcomes of stroke patients who could swallow and who were randomly allocated normal hospital diet or normal hospital diet plus oral nutritional supplements until hospital discharge. The primary outcome was death or poor outcome (modified Rankin scale [MRS] grade 3-5), 6 months after enrollment, measured unaware of treatment allocation. Analysis was by intention to treat.
                Between Nov 1, 1996, and July 31, 2003, 4023 patients were enrolled by 125 hospitals in 15 countries. Only 314 (8%) patients were judged to be undernourished at baseline. Vital status and MRS at the end of the trial were known for 4012 and 4004 patients, respectively. Supplemented diet was associated with an absolute reduction in risk of death of 0.7% (95% CI -1.4 to 2.7) and an increased risk of death or poor outcome of 0.7% (-2.3 to 3.8).
                We could not confirm the anticipated 4% absolute benefit for death or poor outcome from routine oral nutritional supplements for mainly well nourished stroke patients in hospital. Our results would be compatible with a 1% or 2% absolute benefit or harm from oral supplements. These results do not support a policy of routine oral supplementation after stroke. Deglutitive aspiration is common after stroke and can have devastating consequences. While the application of oral sensory stimulation as a treatment for dysphagia remains controversial, data from our laboratory have suggested that it may increase corticobulbar excitability, which in previous work was correlated with swallowing recovery after stroke. Our study assessed the effects of oral stimulation at the faucial pillar on measures of swallowing and aspiration in patients with dysphagic stroke. Swallowing was assessed before and 60 min after 0.2-Hz electrical or sham stimulation in 16 stroke patients (12 male, mean age = 73 +/- 12 years). Swallowing measures included laryngeal closure (initiation and duration) and pharyngeal transit time, taken from digitally acquired videofluoroscopy. Aspiration severity was assessed using a validated penetration-aspiration scale. Preintervention, the initiation of laryngeal closure, was delayed in both groups, occurring 0.66 +/- 0.17 s after the bolus arrived at the hypopharynx. The larynx was closed for 0.79 +/- 0.07 s and pharyngeal transit time was 0.94 +/- 0.06 s. Baseline swallowing measures and aspiration severity were similar between groups (stimulation: 24.9 +/- 3.01; sham: 24.9 +/- 3.3, p = 0.2). Compared with baseline, no change was observed in the speed of laryngeal elevation, pharyngeal transit time, or aspiration severity within subjects or between groups for either active or sham stimulation. Our study found no evidence for functional change in swallow physiology after faucial pillar stimulation in dysphagic stroke. Therefore, with the parameters used in this study, oral stimulation does not offer an effective treatment for poststroke patients. Undernutrition after an acute stroke increases the risk of poor outcome. We wanted to examine the effect of individualized, nutritional support on weight loss and functional outcomes in stroke patients.
                Acute stroke patients at nutritional risk were randomized to either individualized, nutritional care or routine care while in hospital. Patients in the intervention group received an individualized treatment plan aiming to prevent weight loss. In accordance with routine care, the controls did not have such a treatment plan. Patients were reviewed at follow-up after three months. Primary outcome measure was the percentage of patients with weight loss ≥5%. Secondary outcomes measures were quality of life (QoL), handgrip strength and length of hospital stay. This trial is registered with ClinicalTrials.gov, number NCT00163007.
                At follow-up, 20.7% of the intervention group (n = 58) lost ≥5% weight compared with 36.4% in the control group (n = 66) (P = 0.055). The intervention group had a significantly higher increase in QoL score (P = 0.009) and in handgrip strength (P = 0.002). There was no difference in length of hospital stay.
                Individualized, nutritional treatment strategy can prevent clinically significant weight loss and improve QoL in elderly acute stroke patients at nutritional risk.

Oropharyngeal dysphagia is an important disability that occurs after stroke; it contributes to aspiration pneumonia and death, and current modalities for rehabilitation of dysphagia have uncertain efficacy. We therefore examined the role of pharyngeal electrical stimulation (PES) in expediting human swallowing recovery after experimental (virtual) and actual (stroke) brain lesions.
                First, healthy subjects (n = 13) were given 1-Hz repetitive transcranial magnetic stimulation to induce a unilateral virtual lesion in pharyngeal motor cortex followed by active or sham (control) PES. Motor-evoked potentials and swallow accuracy were recorded before and after the lesion to assess PES response. Thereafter, 50 acute dysphagic stroke patients underwent either a dose-response study, to determine optimal parameters for PES (n = 22), or were assigned randomly to groups given either active or sham (control) PES (n = 28). The primary end point was the reduction of airway aspiration at 2 weeks postintervention.
                In contrast to sham PES, active PES reversed the cortical suppression induced by the virtual lesion (F(7,70) = 2.7; P = .015) and was associated with improvement in swallowing behavior (F(3,42) = 5; P = .02). After stroke, 1 PES treatment each day (U = 8.0; P = .043) for 3 days (U = 10.0) produced improved airway protection compared with controls (P = .038). Active PES also reduced aspiration (U = 54.0; P = .049), improved feeding status (U = 58.0; P = .040), and resulted in a shorter time to hospital discharge (Mantel-Cox log-rank test, P = 0.038).
                This pilot study of PES confirms that it is a safe neurostimulation intervention that reverses swallowing disability after virtual lesion or stroke.
                Copyright 2010 AGA Institute. Published by Elsevier Inc. All rights reserved. nasogastric tube (NGT) feeding is commonly used after stroke, but its effectiveness is limited by frequent dislodgement.
                the objective of the study was to evaluate looped NGT feeding in acute stroke patients with dysphagia.
                this was a randomised controlled trial of 104 patients with acute stroke fed by NGT in three UK stroke units. NGT was secured using either a nasal loop (n = 51) or a conventional adhesive dressing (n = 53). The main outcome measure was the proportion of prescribed feed and fluids delivered via NGT in 2 weeks post-randomisation. Secondary outcomes were frequency of NGT insertions, treatment failure, tolerability, adverse events and costs at 2 weeks; mortality; length of hospital stay; residential status; and Barthel Index at 3 months.
                participants assigned to looped NGT feeding received a mean 17% (95% confidence interval 5-28%) more volume of feed and fluids, required fewer NGTs (median 1 vs 4), and had fewer electrolyte abnormalities than controls. There was more minor nasal trauma in the loop group. There were no differences in outcomes at 3 months. Looped NGT feeding cost 88 pounds sterling more per patient over 2 weeks than controls.
                looped NGT feeding improves delivery of feed and fluids and reduces NGT reinsertion with little additional cost. Treatment options for stroke-related dysphagia are currently limited. In this study, we investigated whether noninvasive brain stimulation in combination with swallowing maneuvers facilitates swallowing recovery in dysphagic stroke patients during early stroke convalescence.
                Fourteen patients with subacute unilateral hemispheric infarction were randomized to anodal transcranial direct current stimulation (tDCS) versus sham stimulation to the sensorimotor cortical representation of swallowing in the unaffected hemisphere over the course of 5 consecutive days with concurrent standardized swallowing maneuvers. Severity of dysphagia was measured using a validated swallowing scale, Dysphagia Outcome and Severity scale, before the first and after the last session of tDCS or sham. The effect of tDCS was analyzed in a multivariate linear regression model using changes in Dysphagia Outcome and Severity Scale as the outcome variable after adjusting for the effects of other potential confounding variables such as the National Institutes of Health Stroke Scale and Dysphagia Outcome and Severity scale scores at baseline, acute ischemic lesion volumes, patient age, and time from stroke onset to stimulation.
                Patients who received anodal tDCS gained 2.60 points of improvement in Dysphagia Outcome and Severity scale scores compared to patients in the sham stimulation group who showed an improvement of 1.25 points (P=0.019) after controlling for the effects of other aforementioned variables. Six out 7 (86%) patients in tDCS stimulation group gained at least 2 points of improvement compared with 3 out 7 (43%) patients in the sham group (P=0.107).
                Because brain stem swallowing centers have bilateral cortical innervations, measures that enhance cortical input and sensorimotor control of brain stem swallowing may be beneficial for dysphagia recovery. The aim of this study was to assess the effectiveness of neuromuscular electrical stimulation in patients with dysphagia caused by stroke.
                Thirty-six subjects were randomized into experimental and control groups. The control group was given thermal-tactile stimulation treatment only, while in the experimental group neuromuscular electrical stimulation and thermal-tactile stimulation treatments were applied simultaneously. Swallowing function was assessed before and 4 weeks after treatment, and evaluated via the swallow function scoring system, penetration-aspiration scale, and pharyngeal transit time. In addition, the discomfort score during the treatments and the satisfaction score 4 weeks after the treatments were measured.
                Twenty-eight persons with dysphagia completed the study, 16 in the experimental group and 12 in the control group. Both groups showed improvement, but the experimental group showed more significant improvement in the swallow function scoring system, penetration-aspiration scale and pharyngeal transit time than the control group. The patient's discomfort score did not show statistically significant differences in either group, but the satisfactory score was higher in the experimental group.
                The results suggest that neuromuscular electrical stimulation combined with thermal-tactile stimulation is a better treatment for patients with swallowing disorders after stroke than thermal-tactile stimulation alone. The objective of this study was to investigate whether protein-calorie supplementation may enhance the cognitive retrieval of patients with stroke.
                A randomized, double-blind, controlled pilot clinical trial was performed comparing diet and diet plus protein-calorie supplementation regimens. The subjects were 48 patients with subacute stroke (>or14 days from index event). Anthropometric and nutritional (3-day diary) variables, cognitive function (Mini-Mental State Examination; MMSE) were determined before and 21 days after randomization in control and daily supplemented group (formula providing 250 kcal + 20 g protein).
                At day 21 after starting the protocol, only the supplemented group significantly improved their performance to MMSE (log(10)MMSE +0.6+/-0.4 score; P=0.01 from baseline).
                Protein-calorie supplementation may enhance the recovery of cognitive function in subacute stroke patients. nan Swallowing dysfunction after stroke is common, but there is little reliable evidence for how the disorder should be managed. This study compared standard low-intensity and high-intensity behavioural interventions with usual care for dysphagia.
                306 patients with clinical dysphagia admitted to hospital with acute stroke were randomly assigned to receive usual care (n=102), prescribed by the attending physician; standard low-intensity intervention (n=102), comprising swallowing compensation strategies and diet prescription three times weekly for up to a month; or standard high-intensity intervention and dietary prescription (n=102), at least daily for up to a month. The primary outcome measure was survival free of an abnormal diet at 6 months. Analysis was done by intention to treat. This study is registered with ClinicalTrials.gov, number NCT00257764.
                60 patients died and three patients were lost to follow up before the 6-month analysis. Of patients randomly allocated usual care, 56% (57/102) survived at 6 months free of an abnormal diet compared with 67% (136/204) allocated standard swallowing therapy (relative risk 1.19, 95% CI 0.98-1.45). Standard swallowing therapy was associated with a non-significant trend toward a reduction in death (0.80, 0.5-1.3), institutionalisation (0.69, 0.4-1.1), and dependency (1.05, 0.8-1.3); a significant reduction in swallowing-related medical complications (0.73, 0.6-0.9), chest infection (0.56, 0.4-0.8), and death or institutionalisation (0.73, 0.55-0.97); and a significant rise in the proportion of patients regaining swallowing function (1.41, 1.03-1.94) by 6 months. Compared with usual care and low-intensity therapy, high-intensity therapy was associated with an increased proportion of patients who returned to a normal diet (p=0.04) and recovered swallowing (p=0.02) by 6 months.
                These data show a consistent trend towards more favourable outcomes in dysphagic stroke patients who are assigned a standard programme of early behavioural swallowing intervention, including active therapeutic approaches and dietary modification. following a stroke, morbidity and mortality is high, with aspiration pneumonia being a common complication.
                to determine the levels of colonisation by and isolation of aerobic Gram-negative bacteria (AGNB) in acute stroke patients and determine the effect of selective decontamination of the digestive tract (SDD) on oral flora and whether it reduces both morbidity and mortality after an acute stroke.
                a prospective, randomised, placebo-controlled double blind trial.
                acute stroke assessment units of three hospitals in the northwest of England.
                203 patients admitted to hospital following a first acute stroke.
                participants were randomised to SDD oral gel or placebo. Swallow was assessed on admission to hospital, and oral swabs were obtained thrice weekly. Demographic and clinical data were recorded.
                203 patients (106 males and 97 females) participated, of whom 20 died during their hospitalisation, 19 withdrew and full follow-up was obtained for the remaining 164. A total of 122 AGNB were isolated in 105 samples from 48 patients. Abnormal swallow on admission was found in 58 patients (29%). A total of 34 patients carried a single gram-negative micro-organism that was present on one or more occasions. More than one AGNB was carried in 14 patients, and organisms were significantly more likely to be isolated from the placebo group than the active group during weeks 2 and 3 of treatment (P = 0.034, chi-squared). Seven patients in the placebo group and one in the treatment group developed pneumonia (P = 0.029, Fisher's exact test).
                high carriage of and colonisation by AGNB was found within this study, which was reduced by the addition of SDD. Although SDD reduced the presence of both organisms and documented episodes of pneumonia, mortality remained unchanged. Dysphagia following stroke is common problem and is of particular concern because of its potental for malnutrition. Nasogastric (NG) and percutaneous endoscopic gastrostomy (PEG) tube feeding are recognized methods for nutritional support for patients with persistent neurologic dysphagia. However, the former is associated with tube dislodgement and blockage that might compromise the patients' nutritional status. There have been few randomized prospective studies to date comparing the efficacy and safety of these 2 modes of dysphagia management in stroke patients. The objective of this study was to compare PEG with NG tube feeding after acute dysphagic stroke in terms of nutritional status and treatment failure. This was a randomized prospective clinical trial. A total of 23 consecutive patients who fulfilled the criteria were recruited from the medical wards in Hospital Universiti Kebangsaan Malaysia. The diagnosis of stroke (acute cerebral infarct) was based on clinical and brain computed tomographic (CT scan) findings; and the diagnosis of dysphagia was done clinically by using the 'swallowing test'. At recruitment, upper-arm skin fold thickness (triceps and biceps) and mid-arm circumference were measured; and blood was drawn for serum albumin level. They were then followed up at 4 weeks where the above tests were repeated. A total of 22 patients completed the study (12 patients in the NG group and 10 patients in the PEG group). Serum albumin levels (p = 0.045) were significantly higher in the PEG as compared to the NG group at 4 weeks post-intervention. There were statistically significant improvements in serum albumin level (p = 0.024) in the PEG group; and statistically significant reductions in serum albumin level (p = 0.047) in the NG group 4 weeks after the intervention. However, there were no significant differences in anthropometric parameters between the two groups and no significant changes in these parameters for each group 4 weeks after the intervention. Treatment failure occurred in 5 out of 10 patients (50.0%) in the NG group, but none in PEG group (p = 0.036). PEG tube feeding is more effective than NG tube feeding in improving the nutritional status (in terms of the serum albumin level) of patients with dysphagic stroke. NG tube feeding, in fact, reduced the nutritional status (in terms of the serum albumin level) of the patients. Poor nutrition is a common complication of strokes severe enough to require inpatient rehabilitation. We therefore tested whether intensive nutritional supplements given to undernourished patients from the time of their admission to a specialized stroke rehabilitation service would improve patient outcomes.
                Randomized, prospective, double-blind, single center study comparing intensive nutritional supplementation to routine nutritional supplementation in 116 undernourished patients admitted to a stroke service. The analysis included the 90% of patients who were not lost to follow-up due to acute or subacute hospitalization (n = 102; 51 in each group). The nutritional supplements are commercially available and Food and Drug Administration approved. The primary outcome variable was change in total score on the Functional Independence Measure (FIM). The secondary outcome measurements included the FIM motor and cognitive subscores, length of stay (taken from day of admission), 2-minute and 6-minute timed walk tests measured at admission and on discharge, and discharge disposition (home/not home).
                Patients receiving intensive nutritional supplementation improved more than those on standard nutritional supplements on measures of motor function (total FIM, FIM motor subscore, 2-minute and 6-minute timed walk tests, all significant at p < 0.002). They did not, however, improve on measures of cognition (FIM cognition score). A higher proportion of patients who received the intensive nutritional supplementation went home compared to those on standard supplementation (p = 0.05).
                Intensive nutritional supplementation, using readily available commercial preparations, improves motor recovery in previously undernourished patients receiving intensive in-patient rehabilitation after stroke. To compare percutaneous endoscopic gastrostomy and nasogastric tube feeding after acute dysphagic stroke.
                Randomised prospective study of inpatients with acute stroke requiring enteral nutrition.
                One university hospital (Nottingham) and one district general hospital (Derby).
                30 patients with persisting dysphagia at 14 days after acute stroke: 16 patients were randomised to gastrostomy tube feeding and 14 to nasogastric tube feeding.
                Six week mortality; amount of feed administered; change in nutritional state; treatment failure; and length of hospital stay.
                Mortality at 6 weeks was significantly lower in the gastrostomy group with two deaths (12%) compared with eight deaths (57%) in the nasogastric group (P < 0.05). All gastrostomy fed patients (16) received the total prescribed feed whereas 10/14 (71%) of nasogastric patients lost at least one day's feed. Nasogastric patients received a significantly (P < 0.001) smaller proportion of their prescribed feed (78%; 95% confidence interval 63% to 94%) compared with the gastrostomy group (100%). Patients fed via a gastrostomy tube showed greater improvement in nutritional state, according to several different criteria at six weeks compared with the nasogastric group. In the gastrostomy group the mean albumin concentration increased from 27.1 g/l (24.5 g/l to 29.7 g/l) to 30.1 g/l (28.3 g/l to 31.9 g/l). In contrast, among the nasogastric group there was a reduction from 31.4 g/l (28.6 g/l to 34.2 g/l) to 22.3 g/l (20.7 g/l to 23.9 g/l) (P < 0.003). In addition, there were fewer treatment failures in the gastrostomy group (0/16 versus 3/14). Six patients from the gastrostomy group were discharged from hospital within six weeks of the procedure compared with none from the nasogastric group (P < 0.05).
                This study indicates that early gastrostomy tube feeding is greatly superior to nasogastric tube feeding and should be the nutritional treatment of choice for patients with acute dysphagic stroke. Up to one-third of patients experience swallowing problems in the period immediately after a stroke.
                To investigate the therapeutic effect of repetitive transcranial magnetic stimulation (rTMS) on post-stroke dysphagia.
                Twenty-six patients with post-stroke dysphagia due to monohemispheric stroke were randomly allocated to receive real (n = 14) or sham (n = 12) rTMS of the affected motor cortex. Each patient received a total of 300 rTMS pulses at an intensity of 120% hand motor threshold for five consecutive days. Clinical ratings of dysphagia and motor disability were assessed before and immediately after the last session and then again after 1 and 2 months. The amplitude of the motor-evoked potential (MEP) evoked by single-pulse TMS was also assessed before and at 1 month in 16 of the patients.
                There were no significant differences between patients who received real rTMS and the sham group in age, hand grip strength, Barthel Index or degree of dysphagia at the baseline assessment. Real rTMS led to a significantly greater improvement compared with sham in dysphagia and motor disability that was maintained over 2 months of follow-up. This was accompanied by a significant increase in the amplitude of the oesophageal MEP evoked from either the stroke or non-stroke hemisphere.
                rTMS may be a useful adjunct to conventional therapy for dysphagia after stroke.
There remains insufficient data on the effect of swallowing therapy, feeding, and nutritional and fluid supplementation on functional outcome and death in dysphagic patients with acute or subacute stroke. Behavioural interventions and acupuncture reduced dysphagia, and pharyngeal electrical stimulation reduced pharyngeal transit time. Compared with NGT feeding, PEG reduced treatment failures and gastrointestinal bleeding, and had higher feed delivery and albumin concentration. Nutritional supplementation was associated with reduced pressure sores, and increased energy and protein intake.
