Relationship between Multiple Predictor Variables and Normal Biodex Eversion-Inversion Peak Torque and Angular Work.

Area of Science:

• Biomechanics
• Kinesiology
• Rehabilitation Science

Background:

• Establishing normative data is crucial for setting effective treatment goals in physical therapy.
• Understanding the relationship between physical characteristics and isokinetic performance can enhance rehabilitation strategies.

Purpose of the Study:

• To generate predictive models that correlate isokinetic ankle testing performance with anthropometric and demographic variables.
• To provide a basis for developing individualized patient rehabilitation programs.

Main Methods:

• Recruited 44 healthy females and 43 healthy males aged 19-62.
• Measured concentric peak torque and angular work for ankle eversion and inversion using Biodex at 60 and 120 degrees/sec.
• Employed stepwise regression analyses to identify relationships between isokinetic variables and predictors like age, height, weight, body fat, leg girth, and shoe size, with separate analyses for males and females.

Main Results:

• Significant relationships (p < 0.001) were found between multiple predictor variables and isokinetic ankle performance.
• The predictive models demonstrated the influence of anthropometric and demographic factors on muscle strength and work capacity.
• The observed relationships may be partially explained by the limited range of measurements for Biodex eversion and inversion.

Conclusions:

• The developed predictive models can be utilized to establish objective muscle performance goals for patients undergoing rehabilitation.
• This research provides valuable normative data for assessing ankle strength and guiding physical therapy interventions.
