Menopause represents a physiological transition characterized by a progressive decline in estrogen and other sex hormones. These hormonal changes influence musculoskeletal health and may lead to reductions in muscle strength, impaired neuromuscular control, decreased balance capacity, and increased risk of functional decline. Such alterations may negatively affect mobility and quality of life in midlife and older women.
Exercise is widely recognized as an effective non-pharmacological strategy to mitigate the negative musculoskeletal consequences associated with menopause. Previous studies have demonstrated improvements in muscle strength, balance, gait speed, and overall physical function following exercise interventions in this population. However, most interventions focus on global lower limb training and rarely include specific exercises targeting the foot and ankle complex, despite its crucial role in postural control, propulsion during gait, and load distribution.
This randomized controlled trial will evaluate the effectiveness of a structured foot and ankle strengthening program in menopausal women. The study will use a parallel two-group design with blinded outcome assessors and a 1:1 allocation ratio. Participants will be randomly assigned to either an intervention group or a control group.
Approximately 60 women aged between 45 and 65 years who meet the clinical definition of menopause and have low to moderate physical activity levels will be recruited from the University of Málaga and the surrounding community. After baseline assessment, participants will be randomly allocated to the intervention or control group using a computer-generated randomization sequence with permuted blocks.
The intervention will consist of a 12-week progressive exercise program specifically designed to strengthen intrinsic and extrinsic foot muscles, improve ankle function, enhance neuromuscular control, and promote functional capacity of the lower limb. Participants in the intervention group will perform one supervised weekly session at the University of Málaga and four home-based exercise sessions per week. The control group will maintain their usual physical activity without participating in the exercise program.
Assessments will be conducted at baseline and after the 12-week intervention period by evaluators blinded to group allocation. Outcome measures will include isometric ankle strength measured by hand-held dynamometry, intrinsic foot muscle function tests, gait speed and spatiotemporal gait parameters measured using the OptoGait® system, balance performance assessed by the Single-Leg Stance Test, self-reported foot function using the Foot and Ankle Ability Measure (FAAM-ADL), and health-related quality of life measured with the EuroQol-5D questionnaire.
The findings of this trial will contribute to understanding the role of targeted distal strengthening interventions in improving functional capacity and mobility in menopausal women and may support the development of clinically applicable exercise programs for this population
