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.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

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.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

Yes

Sampling Method

Non-Probability Sample

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.

Description

Inclusion Criteria:

female gender, age ≥ 60 years independent ambulation adequate cognitive ability.

Exclusion Criteria:

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).

Study record dates

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
September 10, 2020

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
