The Function in Sitting Test Calculator is designed to evaluate an individual’s ability to perform a variety of tasks while seated. This assessment tool is widely used by physical therapists and other rehabilitation professionals to measure the sitting balance and functional performance of patients, particularly those recovering from neurological injuries or surgeries that affect mobility.
Formula of Function in Sitting Test Calculator
The FiST utilizes a scoring system that ranges from 0 to 4, with each score representing the level of assistance required by the individual to complete the task:
- 4: Independent – The individual completes the task independently and successfully.
- 3: Verbal cues/increased time – The individual completes the task independently and successfully but may require verbal cues or additional time.
- 2: Upper extremity support – The individual needs to use upper extremities (UE) for support or assistance to complete the task successfully.
- 1: Needs assistance – The individual is unable to complete the task without physical assistance. The level of assistance (minimal, moderate, or maximal) should be documented.
- 0: Dependent – The individual requires complete physical assistance and is unable to complete the task successfully even with assistance.
This scoring system enables therapists to quantify a patient’s progress over time, providing a clear framework for evaluating improvements or regressions in sitting function.
Score Interpretation
| Total Score Range | Level of Sitting Function | Description |
|---|---|---|
| 53 – 56 | Full Independence | The individual can perform all tasks independently without any assistance or verbal cues. This score indicates excellent sitting balance and functional ability. |
| 45 – 52 | High Moderate Independence | The individual performs most tasks independently. They may require occasional verbal cues or minimal assistance for more challenging tasks. |
| 37 – 44 | Moderate Independence | The individual needs intermittent assistance or verbal cues to perform tasks. Upper extremity support is frequently utilized. |
| 29 – 36 | Low Moderate Independence | The individual consistently requires physical assistance or upper extremity support to perform tasks. Independence is compromised, but not absent. |
| 21 – 28 | High Dependence | The individual is highly dependent on physical assistance for most tasks. They can exhibit minimal independent actions in sitting. |
| 13 – 20 | Moderate Dependence | The individual requires extensive assistance to perform any tasks in a seated position. Independent sitting may be unsafe without precautions. |
| 0 – 12 | Full Dependence | The individual is unable to perform any tasks independently while seated. Continuous support is required for maintaining seated posture. |
Clinical Application
This scoring interpretation helps therapists set realistic goals, predict patient outcomes, and develop appropriate rehabilitation strategies. For instance:
- Patients scoring 53 – 56 might focus on maintaining their independence and exploring more complex activities to enhance their quality of life.
- Patients scoring 29 – 36 may benefit from targeted interventions aimed at reducing the need for support and increasing independence.
- Patients scoring 0 – 12 will require a focus on basic functional improvements and safety in seated positions.
Example of Function in Sitting Test Calculator
Consider a patient recovering from a stroke, undergoing an assessment with the FiST Calculator. The therapist asks the patient to reach forward while seated. The patient leans forward, using their arms for balance, and successfully reaches the target. According to the FiST scoring system, this patient would receive a score of 2, indicating that while they can complete the task, they require the use of their upper extremities for support.
Most Common FAQs
A score of 0 signifies that the individual is dependent and requires complete physical assistance to perform the seated task. It highlights a need for intensive rehabilitation and support.
The FiST Calculator is primarily designed for patients with mobility or neurological issues that affect their sitting function. It’s applicable across a wide range of conditions, but a thorough evaluation by a healthcare professional is essential to determine its suitability for each patient.
The frequency of FiST administration depends on the patient’s condition and the discretion of the healthcare provider. It’s commonly used at the beginning of a rehabilitation program and periodically thereafter to monitor progress.
