Effectiveness of Retrieval Practice on Prospective Memory Deficits in Mild to Moderate Tramatic Brain Injury patients

BACKGROUND: Impairment of prospective memory (PM) is common following traumatic brain injury (TBI) and negatively impacts on independent living, compensatory & Remedial approach to PM rehabilitation have been found to minimize the impact of PM impairment in adults with TBI ; however poor self- awareness after TBI poses a major barrier to the generalization of these strategies in daily life. OBJECTIVES: The aims of the study is to find out the effectiveness of Retrieval practice of rehabilitation on prospective memory deficits for mild to moderate TBI patient. METHODS: 20 participants were recruited for the study. Of which 10 participants underwent Retrieval practice and 10 underwent compensatory training with traditional memory training. The participants were administered with Monstreal Cognitive Assessment (MOCA), Prospective and Retroceptive Memory Questionnaire (PRMQ), Cambridge prospective Memory test (CAMPROMT) and Cambridge prospective memory test (CAMPROMT) used as a outcome measure. The study period was for 2 weeks of 8 sessions given for the both the control group and experimental group. RESULTS: The pre test in experimental group had a mean of 17.7(N=10) and control group had a mean of 19.8(N=10 Comparison between the experimental and control group of CAMPROMT scores of various timeline is no significant difference (p > 0.05) in the pretest and post test of AMPROMT of the experimental group and the pretest and post test of CAMPROMT of the control group. on comparison within pretest and posttest results of experimental group and control group on the scales of a CAMPROMT on 1st week and 2nd week showed statistical significance. the effect size of CAMPROMT of experimental group indicated that statically significance and greater effect size, F(1.373,12.354) =45.466, P < .005, and control group scores indicated that statically significance and medium effect size , F(1.63,14.7) = 11.270, P < .005. CONCLUSION: Both the retrieval practice and the compensatory training were found to be effective in improving prospective memory in patients with TBI. Best clinical suggestion for intervention would be to alternate the use of both retrieval practice and compensatory techniques as intervention to achieve maximum benefits
