Long-Term Stability of Short-Term Intensive Language-Action Therapy in Chronic Aphasia: A 1-2 year Follow-Up Study.

Area of Science:

• Neurology
• Speech-Language Pathology

Background:

• Intensive aphasia therapy, including intensive language-action therapy (ILAT), shows short-term benefits for chronic aphasia.
• Long-term maintenance of ILAT effects remains under-investigated.

Purpose of the Study:

• To assess the long-term stability of treatment effects from intensive language-action therapy (ILAT) in patients with chronic aphasia.
• To evaluate maintenance of ILAT benefits over a period of 8-30 months post-intervention.

Main Methods:

• 38 patients with chronic aphasia underwent ILAT (6-12.5 hours/week for 2-4 weeks).
• Participants were reassessed 8-30 months after treatment completion using the Aachen Aphasia Test.

Main Results:

• Significant improvements in language functions were observed post-ILAT and maintained up to 2.5 years.
• Younger patients (<60 years) showed better preservation of treatment gains.
• Communicative efficacy measures showed initial improvement but inconsistent long-term stability.

Conclusions:

• Intensive language-action therapy (ILAT) leads to durable improvements in chronic aphasia, maintained for at least 2.5 years.
• Findings support the potential shift towards intensive therapy models in clinical practice for sustained patient benefit.
