Repetitive Transcranial Magnetic Stimulation/Behavioral Intervention Clinical Trial: Long-Term Follow-Up of Outcomes in Congenital Hemiparesis.

ABSTRACT: The purpose of this study was to examine long-term outcomes of nonpharmacological intervention in children and adolescents with stroke utilizing repetitive transcranial magnetic stimulation (rTMS) to the primary motor cortex combined with constraint- induced movement therapy (CIMT) to improve motor function in the paretic hand. Outcome measures included function, satisfaction, and medical status review.Fourteen of the original 19 participants (74%) from our rTMS/CIMT clinical trial (real rTMS+CIMT, n?=?8; and sham rTMS+CIMT, n?=?6) were evaluated. The median age of the subjects at follow up was 13.4 years (range 11-20 years old, 50% male). Median time to follow-up was 47.5 months (range 21-57 months). Descriptive statistics were conducted using frequencies and counts. Motor performance was measured using the Assisting Hand Assessment (AHA) and Canadian Occupational Performance Measure (COPM). Satisfaction was reported with use of the COPM and TMS Tolerance Survey. Open-ended interview was conducted for feedback on study experience and subjective perspectives of current functional status.Overall, seven of eight individuals who received real rTMS and five of six individuals who received sham rTMS maintained or improved AHA scores. Six of 14 participants reported new onset of co-occurring conditions (four individuals in the real rTMS group, two individuals in the sham rTMS group). The majority (86%) of participants reported study satisfaction. Review of medical status revealed co-occurring conditions including: Epilepsy, obsessive-compulsive disorder, anxiety, depression, unspecified mood disorder, and undiagnosed inattentiveness.Long-term outcomes of rTMS/CIMT in pediatric stroke were investigated. Variability in performance and unattributed symptoms were noted. Considering the prevalence of co-occurring conditions in children and adolescents with stroke, new-onset symptoms were not attributed to original intervention. With the small sample size, the impact of rTMS on long-term outcomes cannot be fully determined from these data. Characterizing long-term outcomes through performance, participant perspectives, and medical status allows comprehensive assessment of rTMS/CIMT intervention efficacy.

Project description:BackgroundIt 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.ObjectivesTo assess the efficacy and safety of rTMS for improving function in people with stroke.Search methodsWe 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 criteriaWe included randomised controlled trials comparing rTMS therapy with sham therapy or no therapy. We excluded trials that reported only laboratory parameters.Data collection and analysisTwo review authors independently selected trials, assessed trial quality and extracted the data. We resolved disagreements by discussion.Main resultsWe 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' conclusionsCurrent 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.
