Goniometry
Goniometry (TU)
Question | Answer |
---|---|
What is goniometry used for? | Presence of dysfunction related to muscles, tendons, or joints., Establishing a diagnosis, Developing treatment goals, Evaluating progress or the lack of it, Modify treatment based on the progress, Measurement of ROM |
First step in goniometric sequence | Place the patient in the recommended position |
Second step in the goniometric sequence | Palpate relevant bony landmarks |
Third step in the goniometric sequence | Stabilize the proximal joint segment |
Fourth step in goniometric sequence | Align the goniometer |
Fifth step in the goniometric sequence | While keeping the the goniometer on the patient. Move the distal segment through the available range. |
6th step in goniometric sequence | Determine the ROM value then return distal segment back to starting position. |
Normative ROM values stay the same throughout a person's life? | False - as a person ages, ROM values will likely decrease due to changes in joint integrity, muscle flexibility/elasticity. |
A goniometer is used to measure what types of ROM? | Active and Passive |
When should ROM measurements not be performed? | Joint dislocation, fracture, post-surgical patients when movement would disrupt the healing process, extreme osteoporosis or boney fragility. |
What is the measurement error associated with using the goniometer? | +/- 5 degrees |
Define range of motion (ROM). | The physiologic arc of motion occurring at a joint. |
What is the difference between ROM and joint mobility? | ROM is the physiologic arc of motion occurring at a joint. Joint mobility is the accessory motion of a joint (the two articular surfaces move on each other - concave/convex rule). |
What are the 3 types of ROM? | 1 - Active, 2- Active-assisted, 3 - Passive |
What factors can affect ROM? | Muscle length, muscle strength, joint structure/function |
Why do you use a standardized procedure for ROM assessment? | To improve the reliability of the measurement. |
When may you not decide to use the standardized ROM assessment procedures? | To account for patient comfort, fear, patient injury, therapist preference. |
When assessing ROM of the upper extremity, you should start with which side? | Uninvolved side first |
What are the two instruments commonly used to measure ROM? | Goniometer and Inclinometer |
How reliable is the goniometric process? | The reliability of the goniometric process depends on the consistency of the performance including instrument used, client position, stabilization and more. |
Is using a goniometer a valid assessment? | Yes, it is valid because the goniometer is a tool used to measure angles (measures what it is intended to do). |
