Culturally Appropriate Stimuli for Cognitive Neuropsychology-Based Treatment "Intensive Language Action Therapy (ILAT)".

ABSTRACT:

Context

A standardized set of picture stimuli for neuro-language disorder has been long overdue.

Aims

To develop a standardized set of 303 pictures for use in experiments of Intensive Language Action Therapy (ILAT).

Methods and material

Several sources with standardized picture stimuli having culturally unbiased features were studied. Among those studies two prime sources (1) Snodgrass & Vanderwart (1980), 127 (89+37) items and (2) Neininger & Pulvermuller (2002), 147 (89+56) items were used extensively. Out of 303 stimuli, 89 items were common to both principle sources. An Indian study by George & Mathuranath (2007) has also been taken as an additional source. Line drawing stimuli were standardized on four variables of central relevance to memory and cognitive processing: name agreement, image agreement, familiarity, and visual complexity.

Statistical analysis used

All measures related to 303 concepts i.e. % correct, H statistics, familiarity, image agreement and visual complexity were analysed descriptively.

Results

Low mean and positive skew on H statistics and visual complexity show that many concepts had a high name agreement (13 concepts have H values of .0, and 55 have H values of 0.68 or below, where 0.68 represents consensus among all but few of the subjects on a picture's name) and were visually simple line drawings. The intercorrelations among the four measures were low, suggesting that they are indices of different attributes of the pictures.

Conclusions

Usage of appropriate items/stimuli has immense potential to influence aphasia therapy outcome. This set of pictures and its normative variable has enhanced the ILAT outcome. It could be generalised for other aphasia therapy too to understand its efficacy.

Project description:Neuromodulation technologies, such as transcranial magnetic stimulation (TMS), are promising tools for neurorehabilitation, aphasia therapy included, but not yet in common clinical use. Combined with behavioral techniques, in particular treatment-efficient Intensive Language-Action Therapy (ILAT, previously CIAT or CILT), TMS could substantially amplify the beneficial effect of such behavioral therapy alone (Thiel et al., 2013; Martin et al., 2014; Mendoza et al., 2016; Kapoor, 2017). In this randomized study of 17 subjects with post-stroke aphasia in the chronic stage, we studied the combined effect of ILAT and 1-Hz placebo-controlled navigated repetitive TMS (rTMS) to the right-hemispheric inferior frontal cortex-that is, to the anterior part of the non-dominant hemisphere's homolog Broca's area (pars triangularis). Patients were randomized to groups A and B. Patients in group A received a 2-week period of rTMS during naming training where they named pictures displayed on the screen once every 10 s, followed by 2 weeks of rTMS and naming combined with ILAT. Patients in group B received the same behavioral therapy but TMS was replaced by sham stimulation. The primary outcome measures for changes in language performance were the Western Aphasia Battery's aphasia quotient AQ; the secondary outcome measures were the Boston naming test (BNT) and the Action naming test (Action BNT, ANT). All subjects completed the study. At baseline, no statistically significant group differences were discovered for age, post-stroke time or diagnosis. ILAT was associated with significant improvement across groups, as documented by both primary and secondary outcome measures. No significant effect of rTMS could be documented. Our results agree with previous results proving ILAT's ability to improve language in patients with chronic aphasia. In contrast with earlier claims, however, a beneficial effect of rTMS in chronic post-stroke aphasia rehabilitation was not detected in this study.
