- Brief Summary
This study will be a randomized control trial, which will be conducted on older adults with mild cognitive impairment. A specially designed Exergame balance training will be used for cognitive enhancement in patients with MCI. This training will determine the improvement in executive functioning, balance, speech and electrical activity of the brain.
- Detailed Description
From last few years the line of research for cognitive enhancement has been shifted towards balance training as balance training is considered to directly stimulate the neuronal activity as compare to aerobic training. The previous finding also proposed that in aerobic training it is the intensity of training that improves the neuroplasticity and cognition but it is the neuro-cognitive demands and complexity of the task in balance training that affects the relationship between exercise and cognition in balance training. There is a need to determine the effect of the level of complexity of balance training on neural activity and executive functioning. Exergame augmented balance training is expected to have a better physical and cognitive outcome as compared to traditional balance training.

- Primary Outcome Measures
Name Time Method Montreal Cognitive Assessment 8th weeks The MoCA was administered at baseline to characterize the sample as either normative aging or "screened as MCI" The MoCA consists of eight different subtests to assess overall cognitive impairment. Scores below 24 out of 30 were used to categorize MCI. This scale has a good reliability with Cronbach's alpha of 0.905. Its sensitivity is 88% and specificity is 98%. Assessment will be done at baseline, after the 4th and 8th week.
Digit Span Forward and Backward 8th weeks This test measures working memory's number storage capacity. It requires participants to first listen to a list of numbers and repeat them, with the string length increasing to the maximum of their ability. Digit Span Backward, requires repeating a string of numbers in reverse order. Continuing the pattern above to isolate the executive function component, the ratio of the typically smaller sum of correct interference trials on Digit Span Backward, divided by the typically greater sum of correct basic attention trials on Digit Span Forward. Assessment will be done at baseline, after the 4th and 8th week.
Stroop test 8th weeks Stroop test measure attention, processing speed, cognitive flexibility, and working memory. This test has good specificity (0.85-0.90). Coloured squares (red, green, blue) are presented in rows first (Stroop A), followed by those colour words typed in black ink (Stroop B), followed by incongruent colour words (Stroop C; in which participants will be asked to name the colour of the ink while ignoring the written word). A ratio will be computed to isolate the executive function component of the task. Assessment will be done at baseline, after the 4th and 8th week.
Trails Test 8th weeks Trails test is used to assess selective attention, mental flexibility, visual-spatial skills and motor speed. It requires participants to connect numbered circles in ascending order. Color trails-2, requires individuals to connect numbered circles in consecutive order while also alternating the alphabets of the circle. Reliability and validity are adequate. Higher ratios represent a better executive function. Assessment will be done at baseline, after the 4th and 8th week.
Time Up and Go Test 8th weeks The participants rise from sitting, walk 10 feet, turn around and return to the sitting position. The time it takes to complete the task is the score. Lower scores are better. It has a very good validity of 0.857. Assessment will be done at baseline, after the 4th and 8th week.
Smartphone Gait and Balance Application 8th weeks The system consists of the following three components: i) a smartphone that has an embedded accelerometer, ii) a belt to house the phone on the lower back, iii) and a smartphone balance application. There are six different tasks that the subject have to perform with the system, like, normal walking up to 6 meters, walking with head movement, standing with eyes open and close and standing on a compromised surface with eyes open and close. This app. will calculate mediolateral and anterior-posterior sway during each task. Assessment will be done at baseline, after the 4th and 8th week.
Alzheimer's disease Assessment Scale 8th weeks Alzheimer's disease Assessment Scale will be used for Immediate and Delayed Recall Participants shows a list of 11 words on cards and they recall as many as they are able immediately and also after a delay interval. The number of errors/omissions comprises the score, so lower scores are better. It is a reliable tool with Cronbach's alpha of 0.83. Assessment will be done at baseline, after the 4th and 8th week.
Mini Brief Balance Evaluation Systems 8th weeks It is a reliable and valid tool. The mini Balance Evaluation Systems Test (BES Test) is a 14-item clinical balance assessment tool, developed to assess balance across six contexts of postural control: mechanical constraints, limits of stability, postural response to the induced loss of balance, sensory orientation, and gait. Assessment will be done at baseline, after the 4th and 8th week.
Force Plate 8th weeks Force Plate is a reliable and valid tool for balance assessment (ICC=0.8). In the force platform test, the mean velocity of the mediolateral (ML) and anterior-posterior (AP) movement of the COP will be calculated (mm/s) according to the displacement of the COP during each second. The mean moment of velocity (m m2/s) will be calculated as the mean of the areas covered by COP movement during each second of the Force Platform. Assessment will be done at baseline, after the 4th and 8th week.
Gait Speed Assessment 8th weeks Self-selected gait speed (SSGS), fast gait speed (FGS), Cadence are considered to be decreased in patients with MCI. Gait speed will be assessed over 6 meters, and usual- and fast-pace walking mode. The test will be repeated twice with the mean of the two trials will be used for scoring purposes. Participants will be instructed to walk from a standing start at a pace that was normal and comfortable for them or to walk as fast as they could until they reached the end of the marked path. The participants will be asked to stop when their foot contacted the floor at the end of the walking course. Assessment will be done at baseline, after the 4th and 8th week.
Electroencephalography 8th week An electroencephalography scalp electro-voltage activity (sampling frequency: 128Hz, bandpass hardware filter:1-32Hz) will be used. Delta, theta, beta1 and beta2 will be measured in eye open and closed state. Assessment will be done at baseline, after the 4th and 8th week.
Blood Biomarkers 8th weeks The blood biomarkers will be assessed. A 5-mL blood sample will be obtained from the patient. The blood samples will be withdrawn for analysis of serum. The blood samples will be centrifuged. Samples will be and stored at - 80 °C for further serum marker assays. Assessment will be done at baseline, after the 4th and 8th week. Blood biomarkers BDNF, IGF-2, VEGF, TNFα, total-tau, amyloid beta-42, a-Synuclein, IL-10, IL1 and IL4 will be measured.
- Secondary Outcome Measures
Name Time Method Voice Recording 8th weeks The Voice of all the patients will be recorded. Through voice recording pause length, verbal reaction time, and amount of silence will be assessed.
Each participant performed four spoken tasks. The tasks consisted of a counting backward task, a sentence repeating task, an image description task, and a verbal fluency task. Each task will be recorded entirely to extract specific vocal features, including pause length, verbal reaction time, and amount of silence. Assessment will be done at baseline, after the 4th and 8th week.
