Normative Biomechanical Measures of Reaching in Able-Bodied Adults

A study to obtain normative values and repeatability measures during functional reaching tasks in able-bodied individuals with no functional limitations.

Study Overview

• Status: Completed
• Conditions: Individuals With Functional Limitations Which May Impact Their Forward Reach
• Intervention / Treatment: Other: Modified Functional Reach and Functional Reach

Detailed Description

The study has three main aims: 1) Define the data collection methods, and calculate the repeatability, of joint angles, muscle activation magnitudes, seating pressure, foot pressure, and reach distance during seated and standing reaching activities. 2) Collect normative values of joint angles, muscle activation magnitudes, seating pressure, foot pressure, and reach distance during seated and standing functional reaching tasks in 40 participants with no functional limitations. Descriptive statistics will include calculating the mean, median, standard deviation, and range of the outcome variable values. 3) Compare joint angles, muscle activation magnitudes, seating pressure, foot pressure, and reach distance collected during a seated reaching task to those collected during a standing reaching task.

The data collected may be used in the future as baseline reference and repeatability values of outcome measures against which to compare values from individuals with functional limitations to quantify their functional ability.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Joint angles	Change in measurements of joint angles at the shoulders, hips, knees, and ankles, measured in degrees.	One data collection session, lasting approximately 4 hours
Electromyography	Muscle activity over time and peak muscle activity, measured in volts. Muscles measured: erector spinae, rectus abdominis, gluteus maximus, gluteus medius, medial hamstring, vastus lateralis, gastrocnemius, and tibialis anterior.	One data collection session, lasting approximately 4 hours
Center of pressure excursion	Path of movement of the center of pressure applied by the buttocks to the seating surface and applied by the feet to the floor.	One data collection session, lasting approximately 4 hours
Seated and foot pressures	Plot of pressure magnitude over the surface of the buttocks and the bottom of the feet.	One data collection session, lasting approximately 4 hours
Reach distance	Measurement of the furthest distance reached, measured in centimeters.	One data collection session, lasting approximately 4 hours
