Introduction:
The capacity to maintain stability by keeping the body's center of mass inside the support base is called postural balance. Impaired balance is not limited to neurologic disease patients; it can also occur in healthy individuals. Impaired balance is associated with a higher risk of falls and injuries from falls. To identify patients who are in danger of falling and provide early intervention for those who are, clinicians must assess patients' ability to balance.
What Is Functional Reach Test?
To get more exact data about the participants' balance, researchers and clinics use a variety of clinical instruments. The functional reach test (FRT) is a static balance test that illustrates the upper bounds of stability for standing and reaching forward. A quick and easy method to evaluate functional ability and static balance is the single-leg stance (SLS) test. The Timed Up and Go (TUG) test is a straightforward, efficient, and useful balancing assessment tool that evaluates both functional ability and physical mobility. A variation of the TUG test called TUG with the cognitive dual-task (TUGcog) evaluates a person's capacity to multitask by having them complete a cognitive task in addition to the TUG test. TUGcog helps identify those who are at risk since it can alter equilibrium. Variations in the normative values and balance test performance exist among people reported in other nations, perhaps due to the unique characteristics of these populations that impact the balance controls.
What Is Functional Reach Test Protocol?
The Protocol for the Functional Reach Test: The individual takes the functional reach test while standing. Using a fixed base of support, it measures the difference in centimeters between the arm's length with arms at 90° flexion and the arm's maximum forward reach. A centimeter measuring instrument is used in the test and placed against a wall at shoulder height. According to reports, a fall may be predicted with a reach of 15 cm.
-
Location: Cubicles for physiotherapy.
-
Required Equipment:
-
Wall- A one-meter ruler that measures in centimeters.
-
Placing a ruler at shoulder height on the wall using velcro or tape.
-
Armchair temporary marker a floor-marked line.
Method:
-
Draw a line across the ground.
-
Explain to the participant, while they are in a standing position, check how far they can reach forward. It is crucial to avoid falling and for feet to remain in the same spot. Individuals will be asked to stand sideways next to the wall, and a horizontal ruler will be laid at shoulder height. Next, extend the erect arms before them and form a fist. This is where everything begins. This will be noted on the ruler. Next, while maintaining the fist position with the hands, reach forward without shifting the feet. After that, one can mark this new position.
-
The patient is told to stand close to the wall without touching it and to hold a closed fist with the arm closest to the wall at a 90-degree angle to the shoulder.
-
Lay the ruler flat against the wall and fasten it firmly.
-
Using the ruler, note the beginning position at the third metacarpal head.
-
Tell the patient to "Keep the hands in a fist shape and reach forward as far as they can without taking a step."
-
The third metacarpal's position is noted and annotated. If the patient loses their balance, be close to them to assist.
-
Retake the test.
What Are the Standing Instructions for the Functional Reach Test?
Standing directions for functional reach:
-
The patient is to place their arm closest to a wall, but without touching it, and hold it there with a closed fist at a 90-degree angle to the shoulder.
-
The assessor notes the beginning location on the yardstick at the third metacarpal head.
-
Give the patient the directive to "as far forward as they can reach without taking a step."
-
The third metacarpal's position is noted.
-
The reach distance, often measured in inches, is the difference between the start and end positions determining the score.
-
The mean of the final two trials is recorded when three trials are completed.
What Is the Modified Functional Reach Test?
Modified Functional Reach Exam (Designed for People Who Cannot Stand): It is carried out while the patient is seated in a chair and is using a leveled yardstick placed on the wall at the height of their acromion level in the non-affected arm. The hips, knees, and ankles are 90 degrees bent, and the feet are flat on the ground. The patient's upper extremities are bent to a 90-degree angle as they sit against the chair's back. The measurement for the initial reach is taken along the yardstick, starting from the distal end of the third metacarpal.
What Are the Benefits of the Functional Reach Test?
A clinical evaluation of a person's balance and mobility used in physical therapy and rehabilitation is the Functional Reach Test (FRT). The following are the main advantages of the Functional Reach Test:
-
For Assessing the Balance: The Forward Reaching Balance (FRT) test gauges a person's capacity to stay balanced when reaching forward, which is necessary for everyday tasks like reaching for items on a shelf or staying steady when moving.
-
Fall Risk Assessment: FRT is particularly useful in identifying older adults at an increased risk of falling. Reduced reach distance may indicate a higher risk of falls, which can be avoided by putting the right interventions in place.
-
Early Balance Impairment Detection: FRT can identify balance impairments before they worsen, which enables the implementation of preventative measures and early intervention, lowering the risk of falls or accidents.
-
Functional Independence: The exam assesses a person's capacity to carry out necessary daily tasks, such as getting dressed, taking care of themselves, and reaching for objects, all of which are critical to preserving independence.
-
Rehabilitation Progress: Functional Retinal Imaging (FRT) is a useful modality for tracking the recovery of patients undergoing rehabilitation, including those recuperating from stroke, surgery, or other traumas. Therapists can monitor progress through regular assessments of functional reach and pinpoint areas that require additional care.
Conclusion:
One must maintain static and dynamic balance to walk safely and achieve functional mobility. This calls for the necessity for a valid and dependable method of screening for fall risk. Although it is widely used, the functional reach test (FRT) does not offer some kinematic data, such as translation of the pelvic girdles or shoulders. The goal was to examine video recordings that captured arm orientation, girdle translation, distance traveled, velocity, and period during FRT. We suggested using a cheap, fair-resolution web camera instead of manual measuring for an accurate FRT estimation. Tinetti and MMSE scores were associated with the kinematic characteristics. According to the study's performance values, the cFRT is a legitimate and trustworthy evaluation that yields more precise data about functional reach than a "manual" test.
