The Effectiveness of Thermal Stimulation Plus Conventional Therapy for Functional Recovery After Stroke: A Systematic...

Area of Science:

• Rehabilitation Medicine
• Neuroscience
• Physical Therapy

Background:

• Motor impairments significantly impact post-stroke patient function.
• Identifying cost-effective rehabilitation strategies is crucial for stroke recovery.
• Thermal stimulation presents a potential low-cost adjunct therapy.

Purpose of the Study:

• To evaluate the effectiveness of thermal stimulation combined with conventional therapy for functional recovery in post-stroke patients.
• To synthesize evidence from randomized clinical trials on this therapeutic approach.

Main Methods:

• Comprehensive electronic literature search across multiple databases (MEDLINE, Scopus, EMBASE, etc.).
• Inclusion of randomized clinical trials comparing thermal stimulation plus conventional therapy to conventional therapy alone.
• Independent review of studies for selection, data extraction, and risk of bias assessment.

Main Results:

• Meta-analysis of six studies revealed significant improvements in overall function (MD = 6.92) and motor function (MD = 6.31) with combined therapy.
• Significant positive effects were also observed for walking ability (MD = 1.01).
• Balance showed no statistically significant improvement (MD = 4.41), and effects on daily living activities were non-significant in a subset analysis.

Conclusions:

• Short-term application of thermal stimulation alongside conventional therapy demonstrates statistically significant benefits for functional recovery in stroke survivors.
• The quality of evidence varies from high to very low (GRADE rating), necessitating cautious interpretation.
• Heterogeneity in thermal stimulation protocols (frequency, dosage) limits generalizability; more robust clinical trials are required.
