This group will receive sensorimotor training with cognitive dual-task training in addition to whole body vibration. The participants will perform 36 sessions (3 times per week on alternate days over 12 weeks). The duration of one session for each group will be 60 minutes,

This group will receive sensorimotor training with cognitive dual task training simultaneously. The participants will perform 36 sessions (3 times per week on alternate days over 12 weeks). The duration of one session for each group will be 60 minutes,

This group will receive sensorimotor training with cognitive dual-task training in addition to whole body vibration. The participants will perform 36 sessions (3 times per week on alternate days over 12 weeks). The duration of one session for each group will be 60 minutes, The whole-body vibration will be administered using a vibration machine. This includes asking the patient to stand barefoot on the vibrator platform evenly distributing their body weight on both feet with knees bent at 20 degrees as flexing of knees is a common postural adaptation used to minimize transmission of vibration to the head. The patients will receive the whole body vibration at 30Hz consisting of three sessions per week with at least one day between sessions for 12 weeks. The time for each session will be 15 minutes (five bouts of 2 min) . There will be a rest of 1 minute between each bout of vibration therapy.

The Montreal Cognitive Assessment (MoCA) is a one-page, 30-point cognitive screening measurement scale with 12 subtasks in the MoCA test including memory, visuospatial orientation, executive functioning, phonemic fluency, two-item abstract thinking task, attention, concentration, working memory, language, and orientation to time and place. A score of 26 is a cutoff score to differentiate between normal and abnormal. 18-25 points: Mild cognitive impairment. 10-17 points: Moderate cognitive impairment. Fewer than 10 points: Severe cognitive impairment. Inter-rater Reliability (0.96) Cronbach's alpha (0.79).

The Mini-BESTest is a 14-item test that is a shortened version of the BESTest. It assesses important aspects of dynamic balance, including postural response to perturbation and gait stability. The Mini-BESTest has components of multiple individual balance assessments including items from the Berg Balance Scale, the Dynamic Gait Index, single-limb stance test, functional reach, Timed Up and Go, and modified Clinical Test of Sensory Interaction on Balance as well as a dual-task item and postural response items

The Short Physical Performance Battery (SPPB) allows the evaluation of limitations in the functioning of the lower limbs concerning the lower limb strength by five chair lifts, the balance by the tandem/semi-tandem position, and the walking speed by the 4 m walk. Each component is scored from 0 to 4 and summed to yield scores between 0 (poor) and 12 (best) performance (31). The scores are added together to obtain an overall performance score, with a maximum of 12. A high score is defined as a score above 10, a medium score between 9 and 7, and a low score below 6. (32). Test-retest reliability of the SPPB was high: 0.87 (CI95%: 0.77-0.96)

The Stroop test is a widely used executive function test to evaluate selective attention, speed of information processing, response inhibition and cognitive flexibility. In general, the Stroop effect occurs when individuals are presented with incongruent colour-word stimuli (e.g., the task requires to read the word "red" printed in blue ink or to name the colour of the ink instead of reading the word). Successful performance requires to inhibit an automatic behaviour (i.e., reading) in favour of a less practiced one (i.e., naming the colour of the ink). For all Stroop subtests, the completion times were the shortest for the individuals in the 18-29 age group with the highest education level and longest for the individuals in the 70-83 age group with the lowest education level. The test demonstrated acceptable internal consistency and high test-retest reliability.
