Sit to stand is the most functional task we have discussed thus far. This transitional phase is utilized in multiple settings, from multiple heights and correlates with independent living in the elderly. Think: getting up from the toilet, from a car, from a movie seat, from a park bench, from a curb, from the dining table, etc. Despite the variations there are basic elements of a sit to stand movement which remain constant.
From a biomechanical aspect, three phases of sit to stand exist: phase 1, weight shift; phase 2, transition; and phase 3, lift.
Where would you place these phases within the framework of our normal task analysis?
STEPS FOR TASK ANALYSIS:
1. Consider "normal" execution and basic required elements.
Normal Task Analysis form.docx
Remember your reference:
2. Hypothesize patient's ability
3. Prepare yourself for the needed level of assistance
4. Ask the patient to do the task: "Go ahead and stand up from the chair or bed" (or: "Go ahead and sit down on the bed or chair" for the reverse motion.
4. Observe the INITIATION. Compare it to "normal" and assess if it is effective. (if it is effective and appropriate, and needs no modifying, let it go)
5. Provide assistance as needed to accomplish the task.
Know where to touch: your touch should facilitate the movement. Your movements should align with the needed movement pattern/direction for the task to enhance the success and not "get in the way" of the patient's attempt.
Your Input + the patient's effort = Success.
*** Do Not Correct on the 1st Attempt***
6. REPEAT the task.
This time, provide additional input to substitute for the impairment you hypothesized was limiting the patient's success.
Ask yourself: Did the task become 'easier", more successful, when I added this intentional input?
If so: Add it to your problem list
If not: move on to the next hypothesized impairment
Continue in this fashion until all possible impairments have been assessed.
RESULT: A list of impairments directly impacting the performance of sit to stand. These impairments will be the initial goals of your interventions

HOW TO ASSIST and ASSESS THE TASK OF SIT -STAND
Let's get started with this task!
In the clinic, STS can be a challenging task for YOU and the patient.
This entire video is an assessment of her sit- stand. I assist, tighten/lighten to see where she needs assistance and where she doesn't, then attempt to test/re-test by providing manual and verbal cues to adjust her movement control. You can not do this, however, unless you work from the beginning and know where to put your hands and have a good understanding of what you are trying to accomplish (thus the task analysis)
Watch this video showing how to approach a min assist patient:
There are various methods to use for assisting/assessing the task of sit- stand. Which you choose depends on the patient's needs, your hypothesis of their strengths/weaknesses/capacity, YOUR height and the setting, to name a few.
This video shows variations for body positions to assist/assess this task:
This video shows an approach for a patient needing more assistance, perhaps moderate to maximal assistance:
TEST/ RE-TEST for patient needing more assistance (Step 6 of the Task Analysis)
Watch this example of test/ re-test: You think the patient is not able to complete forward weight sift over the base of support. You can provide input at the scapula and and facilitate anterior pelvic tilt to increase trunk flexion and create forward weight shift prior to lift off.
Here is a video clip for you:
SO, WHAT ABOUT THE ARMS? WHAT IS THEIR ROLE IN STS?
COMMON ERRORS OF THE PT WHEN ASSESSING/ASSISTING STS:
1. Obesity. If a person cannot sufficiently flex the trunk forward or attain anterior pelvic tilt, due to large abdominal size, they may need to scoot first.
2. Lack of strength and power. Due to frailty, post-operative conditions, impaired strength or ROM, a person may lack sufficient power to perform sit to stand task without scooting.
3. Pain. Trunk or limb movement in some, may create an increase in pain therefore limiting the amount of forward excursion required for standing. They may need to scoot.
Here is a video view of scooting:
Hand placement to facilitate scooting:
Objective tests and measures that directly assess sit to stand
1. 30 second chair stand test
2. 5 times sit to stand
3. Modified 30 second sit-to-stand
Objective tests that contain sit to stand elements
1. Berg Balance Scale
2. FIM
3. MiniBestest
4. Tinetti
5. TUG
