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

Joint angles
Change in measurements of joint angles at the shoulders, hips, knees, and ankles, measured in degrees.
Time frame: 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.
Time frame: 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.
Time frame: 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.
Time frame: One data collection session, lasting approximately 4 hours
Reach distance
Measurement of the furthest distance reached, measured in centimeters.
Time frame: One data collection session, lasting approximately 4 hours
