BACKGROUND: The use of facial cross-grafting in acquired recent unilateral facial palsy provides spontaneity and emotional activation. Masseteric nerve for facial animation has mainly been described for reinnervation of neuromuscular transplants, babysitter procedures, or direct facial nerve cooptation. The simultaneous use in a single procedure of cross-facial nerve grafting and masseteric cooptation has not been described. METHODS: Eight patients underwent facial animation using single stage cross-facial nerve grafting and masseteric nerve cooptation. The mean duration of facial palsy was 10.2 months (range, 1-23 months). RESULTS: Voluntary contraction in response to masseteric nerve activation was observed after 2 to 4 months. All patients underwent postoperative rehabilitation and spontaneous contraction was achieved in 7 to 13 months postoperatively. Cosmetic outcomes were evaluated as moderate in 1 patient, good in 5 patients, and excellent in the remaining 2 patients. CONCLUSION: This new technique could provide good results with fast, reliable, and powerful reinnervation, spontaneity, and low morbidity. © 2013 Wiley Periodicals, Inc. Head Neck, 2013.

BACKGROUND: It had been assumed that suppressing the undamaged contralesional motor cortex by repetitive low-frequency transcranial magnetic stimulation (rTMS) or increasing the excitability of the damaged hemisphere cortex by high-frequency rTMS will promote function recovery after stroke. OBJECTIVES: To assess the efficacy and safety of rTMS for improving function in people with stroke. SEARCH METHODS: We searched the Cochrane Stroke Group Trials Register (April 2012), the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2012, Issue 4), the Chinese Stroke Trials Register (April 2012), MEDLINE (1950 to May 2012), EMBASE (1980 to May 2012), Science Citation Index (1981 to April 2012), Conference Proceedings Citation Index-Science (1990 to April 2012), CINAHL (1982 to May 2012), AMED (1985 to May 2012), PEDro (April 2012), REHABDATA (April 2012) and CIRRIE Database of International Rehabilitation Research (April 2012). In addition, we searched five Chinese databases, ongoing trials registers and relevant reference lists. SELECTION CRITERIA: We included randomised controlled trials comparing rTMS therapy with sham therapy or no therapy. We excluded trials that reported only laboratory parameters. DATA COLLECTION AND ANALYSIS: Two review authors independently selected trials, assessed trial quality and extracted the data. We resolved disagreements by discussion. MAIN RESULTS: We included 19 trials involving a total of 588 participants in this review. Two heterogenous trials with a total of 183 participants showed that rTMS treatment was not associated with a significant increase in the Barthel Index score (mean difference (MD) 15.92, 95% CI -2.11 to 33.95). Four trials with a total of 73 participants were not found to have a statistically significant effect on motor function (standardised mean difference (SMD) 0.51, 95% CI -0.99 to 2.01). Subgroup analyses of different stimulation frequencies or duration of illness also showed no significant difference. Few mild adverse events were observed in the rTMS groups, with the most common events being transient or mild headaches (2.4%, 8/327) and local discomfort at the site of the stimulation. AUTHORS’ CONCLUSIONS: Current evidence does not support the routine use of rTMS for the treatment of stroke. Further trials with larger sample sizes are needed to determine a suitable rTMS protocol and the long-term functional outcome. HubMed – rehab

 

Interventions for preventing falls in people after stroke.

BACKGROUND: Falls are one of the most common medical complications after stroke with a reported incidence of 7% in the first week after stroke onset. Studies investigating falls in the later phase after stroke report an incidence of up to 73% in the first year post-stroke. OBJECTIVES: To evaluate the effectiveness of interventions aimed at preventing falls in people after stroke. SEARCH METHODS: We searched the trials registers of the Cochrane Stroke Group (November 2012) and the Cochrane Bone, Joint and Muscle Trauma Group (May 2012), the Cochrane Central Register of Controlled Trials (CENTRAL) in The Cochrane Library 2012, Issue 5, MEDLINE (1950 to May 2012), EMBASE (1980 to May 2012), CINAHL (1982 to May 2012), PsycINFO (1806 to May 2012), AMED (1985 to May 2012) and PEDro (May 2012). We also searched trials registers, checked reference lists and contacted authors. SELECTION CRITERIA: Randomised controlled trials of interventions where the primary or secondary aim was to prevent falls in people after stroke. DATA COLLECTION AND ANALYSIS: Review authors independently selected studies for inclusion, assessed trial quality, and extracted data. We used a rate ratio and 95% confidence interval (CI) to compare the rate of falls (e.g. falls per person year) between intervention and control groups. For risk of falling we used a risk ratio and 95% CI based on the number of people falling (fallers) in each group. We pooled results where appropriate. MAIN RESULTS: We included 10 studies with a total of 1004 participants. One study evaluated the effect of exercises in the acute and subacute phase after stroke but found no significant difference in rate of falls (rate ratio 0.92, 95% CI 0.45 to 1.90, 95 participants). The pooled result of four studies investigating the effect of exercises on preventing falls in the chronic phase also found no significant difference for rate of falls (rate ratio 0.75, 95% CI 0.41 to 1.38, 412 participants).For number of fallers, one study examined the effect of exercises in the acute and subacute phase after stroke but found no significant difference between the intervention and control group (risk ratio 1.19, 95% CI 0.83 to 1.71, 95 participants). The pooled result of six studies examining the effect of exercises in the chronic phase also found no significant difference in number of fallers between the intervention and control groups (risk ratio 1.02, 95% CI 0.83 to 1.24, 616 participants).The rate of falls and the number of fallers was significantly reduced in two studies evaluating the effect of medication on preventing falls; one study (85 participants) compared vitamin D versus placebo in institutionalised women after stroke with low vitamin D levels, and the other study (79 participants) evaluated alendronate versus alphacalcidol in hospitalised people after stroke.One study provided single lens distance glasses to regular wearers of multifocal glasses. In a subgroup of 46 participants post-stroke there was no significant difference in the rate of falls (rate ratio 1.08, 95% CI 0.52 to 2.25) or the number of fallers between both groups (risk ratio 0.74, 95% CI 0.47 to 1.18). AUTHORS’ CONCLUSIONS: There is currently insufficient evidence that exercises or prescription of single lens glasses to multifocal users prevent falls or decrease the number of people falling after being discharged from rehabilitation following their stroke. Two studies testing vitamin D versus placebo and alendronate versus alphacalcidol found a significant reduction in falls and the number of people falling. However, these findings should be replicated before the results are implemented in clinical practice. HubMed – rehab
