• Conditions: Cognitive Impairment; Balance; Quality of Life

• Registration Number: NCT06927882
• Lead Sponsor: Jouf University

Brief Summary

This is a double-blind, randomized controlled trial comparing WBV therapy with a placebo intervention and standard care. A total of 150 participants will be recruited and investigated from Prince Mutib Hospital. Participants will be randomly allocated to one of three groups: WBV therapy, placebo (non-vibrating platform), or control (standard care). The study duration will be 12 weeks, with assessments conducted at baseline, post-intervention (12 weeks), and at a 6-month follow-up.

Protocol Parameters Summary

* Session Frequency: 3 times per week.

* Session Duration: 25 minutes per session.

* Vibration Frequency: 30 Hz.

* Amplitude: 1-2 mm.

* Program Duration: 12 weeks.

Primary Outcome Measures

Name	Time	Method
Montreal Cognitive Assessment (MoCA) for Cognitive Function	6 months	Assessed using the standard Arabic version of the Montreal Cognitive Assessment (MoCA) at baseline, 12 weeks, and 6 months. The tool is a reliable and valid instrument to detect MCI among the elderly. The maximum score is 0-30, with higher scores indicating better cognitive functioning. A score below 26 typically suggests cognitive impairment. These tests evaluate changes in executive function, attention, and overall cognitive ability. The investigator will use the standard Arabic version used among community dwelling Saudi Arabians population with changes in some word to make it suitable for the Arabic speaking Saudi Arabian population

Secondary Outcome Measures

Name	Time	Method
Berg Balance Scale	6 months	Balance was assessed using the Berg Balance Scale (BBS), a validated and reliable 14-item tool for measuring functional balance. Each item was scored from 0 to 4, with a maximum total of 56. Higher scores reflect better balance performance. The Arabic-translated version, previously validated for clinical use, was administered at baseline, 12 weeks, and 6 months.
• Quality of Life	12 weeks	Health-related quality of life (HRQoL) was measured using the Arabic version of the Short Form-36 Health Survey (SF-36). This self-reported tool comprises 36 items that assess eight health domains: physical functioning, role limitations due to physical health, bodily pain, general health perceptions, vitality (energy/fatigue), social functioning, role limitations due to emotional problems, and mental health. Scores for each domain range from 0 to 100, with higher scores indicating better health status. The Arabic version has been culturally adapted and validated for use among Arabic-speaking populations, ensuring both linguistic and conceptual equivalence.
Timed up and go test	6 month	Mobility and fall risk were assessed using the Timed Up and Go (TUG) test. Participants were instructed to stand from a seated position, walk 3 meters, turn around, return, and sit down. The time to complete the task was measured in seconds. Higher times indicate reduced mobility and increased fall risk. A TUG time greater than 13.5 seconds is considered indicative of elevated fall risk.
