Objective: To observe the efficacy of speech and language therapy in one case ofhereditary spastic paraplegia (HSP).

Methods: A patient with HSP who participated in this study from November 2023 toDecember 2023 was treated with repetitive transcranial magnetic therapy (rTMS) combined with speech and language therapy. The pantient's improvement of dysarthriawas assessed by Frenchay dysarthria assessment scale,maximal phonation time (MPT)、speech intelligibility and Oral- diadochokinesis (DDk).

Results: The total score of Frenchay dysarthria assessment scale was 95 before treatmentand 113 after treatment. MPT was 4 seconds before treatment and 10 seconds aftertreatment. Speech intelligibility score was 86 points before treatment and 100 points aftertreatment,The sequential motion rates (SMR) in DDK before treatment were 4, and aftertreatment, the SMR was 9.

Conclusion: Patients with HSP who received rTMS and speech and language therapypromoted improvements in oral motor function, as well as a significant increase in theclarity of their consonants, suggesting that this protocol may improve dysarthria.
