BioAnalysis Software for Gait, Balance and Power Analysis

BioAnalysis

Force Plate Software

AMTI’s BioAnalysis software is a complete analysis suite ideal for gait, balance and power analysis. The BioAnalysis software can be integrated with AMTI’s NetForce data acquisition software to provide a seamless acquisition and analysis system for biomechanics laboratories. Use with any AMTI force platforms – from small sensors like the HE6x6 to large force plates like the BP6001200.

BioAnalysis provides a flexible plot layout scheme for viewing and printing gait and balance reports. Multiple plots can be arranged on a page and multiple data sources can be overlaid on each plot. Once you have arranged the page or report to your satisfaction, it can be saved as a template for subsequent reports.

BioAnalysis also provides a statistical analysis package which allows you to calculate a variety of statistics for a large array of calculated gait, balance and power parameters over a range of selected trials. The statistical results may be printed or exported to text files for further analysis in third-party spreadsheet or analysis software.

BioAnalysis provides three comprehensive analysis modules: Gait, Balance, and Power.

See the Specifications Tables below for more details.

BioAnalysis Analysis Modules:

The Gait Module allows users to identify and mark features on the ground reaction force (GRF) signals such as heel strike, toe-off, maximum deceleration, mid-stance and maximum acceleration. The module provides both stride (from heel strike to toe-off) and body weight normalization for intra-subject comparison.

Gait plots include both normalized and non-normalized versions of force (Fx, Fy, Fz, Mx, My, Mz) vs. Time plots, Center of Pressure (COP) and GRF plots. The Gait Module provides comprehensive algorithms to calculate many useful gait parameters such as: acceleration and deceleration values, impulse values, stance times and intervals, and maxima and minima for many of the measured values. Aggregate statistics may be calculated for selected series of trials (as selected from the trial database) which can be printed or exported to file.
The Balance Module provides a suite of plotting and analyzing tools for balance analysis. This module supports COP (Center of Pressure) plots, 95th percentile ellipse plot, X and Y FFTs, Radius vs. Time, Area vs. Time, Fx and Fy vs. Time plots, and FFT frequency plots. The Balance Module also provides algorithms to calculate many balance-related variables such as the X and Y COP means, standard deviations, path length, radial measures and balance parameters.
The Power Module is useful for weight lifting and various athletic endeavors for which it is desirable to determine the energy expended over time for the particular exercise. The Power Module implements a standard double integration algorithm acting on the reaction force to calculate acceleration, velocity, and displacement over time. By inputting the mass of the system being accelerated (weights, body weight, etc.), the power and energy of the exercise is determined.

Complete analysis suite for gait, balance and power

Available for use with any AMTI multi-axis force platforms, BioAnalysis can be integrated with our NetForce software to provide a complete statistical analysis solution for gait, balance, and power research applications.
