A review of Constraint-Induced Therapy applied to aphasia rehabilitation in stroke patients

Abstract

Constraint-induced aphasia therapy (CIAT) is an intensive therapy model based on the forced use of verbal oral language as the sole channel of communication, while any alternative communication mode such as writing, gesturing or pointing are prevented.ObjectivesThis critical review involved the analysis of studies examining CIAT applied to stroke patients.Methods and ResultsUsing keywords, the Medline database was searched for relevant studies published between 2001 and 2008 (Medline 2001-2008). The critical evaluation of the articles was based on the classifications described by the ASNS (Cicerone adaptation). Two studies were categorized as level Ia, two as level II and one study as level IV.ConclusionsThese recommendations should be interpreted with caution, given the small number of studies involved, but serve as a guideline for future studies in aphasia therapy.

Constraint-induced aphasia therapy in post-stroke aphasia rehabilitation: A systematic review and meta-analysis of randomized controlled trials

“…Aphasia, the acquired language disorder, is a common functional impairment after stroke. Approximately 40–60% of stroke survivors sustain aphasia at chronic stage [ 1 ], which is associated with their life dependence, less social participation, poorer rehabilitation outcomes and worsen quality of life [ 2 – 5 ]. Most conventional interventions for aphasia, such as pharmacological managements and rehabilitation programs (e.g.…”

Playing a team game improves word production in poststroke aphasia

“…Structured linguistic intervention (following a defined protocol) may work better, especially for patients with moderate-to-severe impairments who may find conversation too difficult (see also Lanyon et al, 2013). Structured interventions, however, are mostly delivered one-to-one with the important exception of Constraint-Induced Protocols (CIP), which involve small groups of participants (known as CIAT, CILT, or ILAT-Intensive Language Action Therapy; see Pulvermüller et al, 2001;Difrancesco, Pulvermüller, & Mohr, 2012; for a review, see Balardin & Miotto, 2009;Meinzer, Rodriguez, & Rothi, 2012;Zhang et al, 2017). These protocols share the following defining characteristics: (1) Treatment is delivered in small groups (up to three patients); (2) practice is strictly focused on a verbal, spoken output with other forms of communication either not practiced or actively discouraged (constrained); (3) treatment is intensive where intensity refers to the therapy being delivered both with a high-dose and in a compact way (massed rather than distributed practice); (4) treatment is focused on word production (picture naming); (5) treatment involves shaping, where word production is practiced repeatedly, with different carrier sentences, and different degrees of facilitation; (6) naming is promoted in the context of social requests as part of a card game (Go Fish) where participants ask other participants for matching cards.…”
