The tele-supervised group will perform sessions at home through Zoom Video Communications. Each participant will receive an initial session to set up the device, camera position, lighting, and sound. Therapists will provide real-time supervision and feedback in both groups. Delivery will occur via video calls for the tele group and in person for the onsite group. Training will follow a fixed-priority strategy. Participants will divide attention equally between motor and cognitive tasks. Sessions will last 45 minutes. They will be conducted three times per week for eight weeks. Each session will include: 5 minutes warm-up, 35 minutes dual-task training, 5 minutes cool-down

The onsite group will receive the same dual-task balance training program, delivered face-to-face by a trained therapist at the physical therapy clinic, College of Applied Medical Sciences, Prince Sattam bin Abdulaziz University, with a frequency and duration matched to the tele-supervised group.

The most well-known balance test for evaluating adult balance and fall risk is the Berg Balance Scale (BBS). The 14 items on the BBS have an ordinal scale of 0 to 4, totaling 56 points; a lower score denotes a higher risk of falling. Minimal function is represented by a score of 0, and maximal function is represented by a score of 4. It takes about twenty minutes to finish. The items are evaluated from the static position with increasing difficulty by decreasing the base of support to dynamic activities (Joa, 2024). BBS is reliable and valid in older individuals (Berg et al., 1992; Şahin et al., 2008).

Gait speed will be measured using the 10-Meter Walk Test (10MWT). A 14-meter walkway will be used, and participants will be asked to walk at their typical pace. The time will be recorded throughout the middle 10 meters to account for acceleration and deceleration. Meters per second will be used to measure walking speed; greater numbers denote superior performance. For assessing functional mobility in older persons, the 10MWT is a viable and trustworthy tool (Önal & Kocaman, 2025).

The Trail Making Test Part B (TMT-B) assessed divided attention, executive function, cognitive flexibility, and visual attention. As fast as they can, participants will connect 25 circles that alternate between letters and numbers (1-A-2-B); shorter completion times indicate better performance. For older adults, TMT-B is valid and reliable (Tombaugh, 2004; Sánchez-Cubillo et al., 2009).
