Patients were included in a core stability intervention. It will be done with different stages and increasing gradually.

Standard intervention consisting of exercises aimed at improving balance.

Core stability intervention will be done with different stages and increasing gradually. The training program starts with exercises that isolate specific core muscles but progressing to include complex movements and incorporate core stability in dynamic tasks.

Dynamic balance is going to be assessed with the Mini-Balance Evaluation System Test. It was developed to identify the postural control systems that underly poor functional balance. It contains four subscales: anticipatory postural control, reactive postural control, sensory orientation and stability in gait. It includes 14 items scored on a 3 level ordinal scale. The maximum total score is 28 points with higher scores indicating better balance.

The perceived level of balance confidence is going to be assessed using the Activities-Specific Balance Confidence Scale (ABC). There are 16 items, representing daily activities. Participants are asked to answer, with a score from 0% (not confident at all) to 100% (completely confident) in increments of 10%. A score lower than 67% suggests substantial risk of falling.
