Introduction: Thank you When invited to MSHA – general discussion about the work we are doing with aphasia Rather than simply discussing what we’ve done I chose the one topic of CIAT Growing momentum in the past 10 years. Many facilities are doing book clubs, groups conversation opportunities etc…. This seems to be generating some strong evidence and may have a strong influence on the way we practice

Introduction
What do stroke survivors with apashia want?
1- Meet others with aphasia
"Speak Easy"
"Coffee and Conversation"
Introduction
2- MORE THERAPY!
Constraint Induced Aphasia Therapy
Write down one way you might implement these concepts into your clinical practice.

CIAT History and Evidence
History and evidence
a. Benefits of therapy in the late/"chronic" stages of recovery
b. Regular versus Intense therapy
c. Constraint Induced Aphasia Therapy
CIAT History and Evidence
Sheehan (1947, 1948)
Made the case for additional management of soldiers with aphasia who were dismissed from military care. She outlined the need for analysis and intervention that is tailored to the individual and would include intensity.
Repeated stimulation is essential for acquisition, organization, storage and retrieval
CIAT History and Evidence
Poeck (1989)
Investigated whether intensive language oriented therapy (versus functional) lead to improvement beyond the rate of spontaneous recovery and whether it is effective beyond 12 months post.
CIAT History and Evidence
Poeck (cont)
76 patients received 9 hours of therapy per week over a period of 6-8 weeks. With intensive therapy, improvement went beyond what is expected with spontaneous recovery (92 controls in a previous study who had not received Tx) in 78% of the patients treated up to 4 months and 46% of those treated from 4-12 months.
CIAT History and Evidence
Mackenize (1991)
Attempting to lend support for tx in
general, she concluded that researchers
who did not find tx to be beneficial were
typically provided fewer than 50 hours….
N=5, All had been D/C from Tx (>9mpo). All 4 had
1 month of no Tx, 4 weeks of Intense Tx (2-3 hours
per day), and then no treatment. Skills were gained
and maintained.
CIAT History and Evidence
Conclusion:
Gains were made in one month that one might otherwise make if Tx were spread out over one year.
CIAT History and Evidence
Robey, R. R. (1994). The efficacy of treatment for aphasic persons: A meta-analysis. Brain and Language, 47, 582-608.
Meta Analysis of aphasia literature revealed large effect sizes with Tx provided for 2 or more hours per week.
CIAT History and Evidence
Denes, Perazzolo, Piani & Piccione (1996)
Compared intensive therapy (daily) versus regular (3x/week) in a group of patients with global aphasia .
Following therapy, both groups showed significant improvement in language. Those receiving intensive therapy showed the more favorable outcome.
CIAT History and Evidence
Hinckley, Craig (1998)
Found significant gains in naming after intense therapy vs no treatment and various rates of non-intensive therapy. Therapy provided three hours per week or less was similar to the effect of no therapy.

120 published studies including a single-site, placebo-controlled trial (Taub, 2006) and a large multisite randomized trial (Wolf, 2006).
CIAT History and Evidence
Pradat-Diehl, Tessier (2001)
Present a case of deferred and long term recovery. Therapy began 10 months post stroke with no prior therapy. Gains were reported for at least 6 years.

CIAT History and Evidence
Methods:
17 patients with chronic aphasia
Randomly assigned to conventional therapy (CT) or CIAT
Patients did not differ significantly other than time post stroke. CI group was further post stroke than CT. This was an unforeseeable consequence of the randomization and would likely be considered a disadvantage to the CI
group.
CIAT History and Evidence
CIAT = 3-4 hours per day x10days (avg of 31.5 total hours)
CT = 1 hour per day for 3-5 weeks (avg of 33.9 total hours)
CIAT History and Evidence
CIAT:
Materials
32 cards with 16 pictures (common name or high
frequency word or tailored to individual needs i.e.
minimal pairs sock/rock, white/black)
Hierarchy for requests/constrain
Name
Article or designated object
Syntactically correct sentence
Reinforcement per expectation of the patient- be clear on what is expected
CIAT History and Evidence
CT:
Syndrome specific methods considered
standard in Germany including interventions
such as naming, repetition, sentence
completion, following instructions,
conversations on topics of the patient's choice,
training of various communicative methods.
CIAT History and Evidence
Outcomes
Aachen Aphasia Battery
Significant improvement for CI group (17%)
No significant improvement for CT (2%)
Communication in everyday life:
30% increase for CI
0% reported for CT
CIAT History and Evidence
Agree that plateau exists within first year post stroke.
Scattered reports indicate that therapy can produce improvements after the first year but in these reports, tx was provided for many hours over an extensive period.
CIAT History and Evidence
Future research should investigate:
Whether even more intense Tx can further improve outcome
Whether outcomes are maintained for long periods
Whether outcomes differ between patient profiles i.e. aphasia types, psychiatric issues an in what ways the components of CI contribute to the outcome.
CIAT History and Evidence
Bhogal, Teassell, Speechley, Albert (2003)
Intensity of Aphasia Therapy, Impact on Recovery- Aphasia therapy works
“ lower-intensity over a long period of time does not result in a significant change in outcome. However, more intensive SLT, delivered over a shorter period of time, results in significant improvements in outcome.”
“ It is only by radically reorganizing current provision or increasing the time allocated to speech therapists that their expertise can be effective in the field of chronic aphasia”
CIAT History and Evidence
Meizner 2005
Examined the efficacy of a short-term, intensive language training, constraint-induced aphasia therapy (CIAT) and CIAT-Plus.

Intense therapy for verbal versus non-verbal interventions.

The North Memo more
Intensive Aphasia Treatment Program
The North Memorial Stroke Center is the first in the region to offer this innovative outpatient program that includes many hours of intense therapy over the course of three weeks. The program is designed to help participants relearn old ways or develop new alternative ways of communicating. Patients participate in a combination of individual and group treatments sessions for approximately three and a half hours per day, five days a week. less
