The best transcranial magnetic stimulation (TMS) protocol for post-stroke aphasia (PSA) depends on the language domain and recovery time. Low-frequency repetitive TMS (LF-rTMS) with music and speech-language therapy (SLT) excels in immediate recovery, while dual-rTMS with SLT is optimal for long-term gains.
Area of Science:
- Neuroscience
- Rehabilitation Medicine
- Speech-Language Pathology
Background:
- Speech-language therapy (SLT) is the standard treatment for post-stroke aphasia (PSA).
- Adjunctive transcranial magnetic stimulation (TMS) shows promise for enhancing language recovery in PSA.
- Optimal TMS protocols for specific language domains and recovery time points remain unclear.
Purpose of the Study:
- To compare various TMS protocols combined with SLT for immediate and long-term language outcomes in PSA patients.
- To identify the most effective TMS-SLT combination for different language domains and recovery phases.
Main Methods:
- A systematic literature search was conducted across major databases (Web of Science, EMBASE, PubMed, Cochrane Library) for randomized trials.
- Bayesian network meta-analyses were performed to compare TMS protocols combined with SLT.
- Outcomes were categorized into immediate and long-term language domains, with effect sizes reported as standardized mean differences (SMDs).
Main Results:
- Low-frequency repetitive TMS (LF-rTMS) combined with music and SLT was optimal for immediate improvements in aphasia severity, repetition, naming, and spontaneous speech.
- LF-rTMS plus SLT was best for immediate writing improvements, while Dual-rTMS plus SLT excelled in immediate functional communication and comprehension.
- Dual-rTMS plus SLT demonstrated superiority across all four long-term language outcomes, including overall aphasia severity, comprehension, naming, and repetition.
Conclusions:
- The choice of TMS protocol should be tailored to the specific language domain and the patient's recovery timeline.
- LF-rTMS+Music+SLT is recommended for immediate language gains, whereas Dual-rTMS+SLT is optimal for sustained, long-term recovery.
- While standard TMS+SLT comparisons have moderate-to-high certainty evidence, novel combinations require further head-to-head trials to confirm efficacy due to low-certainty evidence.
