The intervention consisted of a 4-week unstable surface resistance training program (three sessions per week) using bodyweight squats on a foam surface with progressive overload. Outcome measures included lower-extremity muscular strength (30-Second Chair Stand Test), static balance (Romberg test), dynamic balance (Timed Up and Go test), and short-term memory (Wechsler Memory Scale subtests). Assessments were conducted at baseline, during the intervention, and withdrawal phases. Data were analyzed using descriptive statistics, visual inspection, and within- and between-phase comparisons.</span></span></strong></span></span><br> <span style="font-size:12pt"><span new="" roman="" style="font-family:" times=""><strong><span cambria="" style="font-family:">Findings</span></strong><strong><span cambria="" style="font-family:"><span style="font-weight:normal">: The findings indicated improvements in lower-limb strength, static and dynamic balance, and short-term memory during the intervention phase. Although some reduction in performance was observed during the withdrawal&nbsp; phase, overall improvements remained evident compared with initial baseline levels, suggesting a functional relationship between the intervention and observed changes.</span></span></strong></span></span><br> <span style="font-size:12pt"><span new="" roman="" style="font-family:" times=""><strong><span cambria="" style="font-family:">Conclusion</span></strong><strong><span cambria="" style="font-family:"><span style="font-weight:normal">: Unstable surface resistance training may be an effective rehabilitative approach for improving both motor and cognitive functions in older veterans. The simultaneous demand on neuromuscular control and cognitive processing may contribute to observed gains in strength, balance, and memory. However, due to the single-case design, generalization of findings should be made cautiously, and further research with larger samples is recommended.</span></span></strong><strong><span lang="FA" dir="RTL" style="font-weight:normal"></span></strong></span></span><br> &nbsp; Postural Balance,Cognition,Memory 1001 1015 http://ijwph.ir/browse.php?a_code=A-10-2372-2&slc_lang=en&sid=1 M.R.
