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.

Inclusion Criteria:

• 20-59 years of age at time of enrollment

Exclusion Criteria:

• Failure to give consent or follow simple commands
• Score of 7 or above on the QuickDASH Outcome Measure
• Score of 5 or above on the Oswestry Low Back Disability Questionnaire
• Score of 76 or below on the Lower Extremity Functional Scale
• Diagnosis of a neuromuscular disorder (e.g., muscular dystrophy, multiple sclerosis, fibromyalgia)
• Diagnosis of an inner ear balance disorder (e.g., benign paroxysmal positional vertigo)
• Insufficient active range of motion of bilateral shoulders or hips that results in inability to perform forward or lateral reaching tasks
• Any illness or condition which, based on the research team's assessment, will compromise the patient's ability to comply with the protocol, patient safety, or the validity of the data collected during this study
