Study population: a total of 130 participants will be required to participate in the study taking into consideration 10% drop out. This study will recruit approximately 60-75 community-dwelling older women aged 60 years or older who are able to walk independently without the need for assistive devices. Participants will be required to have sufficient cognitive function to understand instructions and complete the assessments, and they must be willing to provide informed consent prior to participation. Demographic information including age, body mass index (BMI), and physical activity level will be collected to describe the sample and to serve as potential covariates in the statistical analyses.
Who may be able to join
- female gender, age ≥ 60 years independent ambulation adequate cognitive ability.
Who cannot join
- a history of neurological disorders affecting balance (e.g., stroke, Parkinson's disease), severe musculoskeletal impairments of the lower limbs (e.g., recent fractures, advanced osteoarthritis, hip or knee replacement) current participation in structured lower limb strength training programs any medical condition contraindicating maximal isokinetic testing (e.g., uncontrolled hypertension or cardiovascular disease).

About this study
Official title: Biomechanical Determinants of Functional Balance in Older Women: Role of Hip and Knee Isokinetic Peak Torques
Postural stability is a key determinant of functional independence in elderly populations, particularly among women due to age-related declines in muscle strength and balance. Despite recognition of the lower limb musculature's importance in balance, the specific contributions of individual hip and knee muscles to postural control remain insufficiently characterized. Therefore, the main aims of this research were to examine correlations among all major hip and knee muscles and functional balance, as measured by the Berg Balance Scale (BBS), in elderly women in addition to identifying which hip and knee muscles serve as independent predictors of functional balance via multiple regression analysis.

A cross-sectional observational design was employed on 130 older women. Peak torque (PT) of hip and knee muscles were measured by Biodex Isokinetic Dynamometer. Balance was measured using Berg Balance Scale (BBS) scale.

Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 13 Apr 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Egypt. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
peak torques of hip flexors, extensors, abductors and adductors (time frame: one month). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 13 Apr 2026.
