COMPLETE SPECIFICATION
The following specification particularly describes the invention and the manner in which it is to be performed:

Field of the Invention
The present invention relates to healthcare technology, specifically targeting the niche of physiotherapy. Within this field, it addresses a critical gap by introducing a ground-breaking device for objectively measuring sensory function. Sensory evaluation is paramount in physiotherapy, influencing diagnosis, prognosis, and treatment planning. This invention revolutionizes sensory assessment by integrating advanced sensors and controls to measure pressure, temperature, and vibration sensations. In the present device, different sensors are used and value can be increase or decrease through different knobs. At the same time, it will display on a Light-Emitting Diode (LED) screen and compare those with normative reference values and also use them for modification of treatment plans and prevention purposes.

Background of the Invention
Examination of sensory function contributes critical information for establishing a physical therapy diagnosis and prognosis, identifying anticipated aims and expected outcomes, and developing a Plan of Care. An important feature of the examination includes determining the pattern (specific boundaries) of sensory involvement. Periodic re-examination provides critical data on changes in the status of the patient and in determining progress toward the aims and outcomes. Individual tests for each sensory modality have been presented.
Reliability of these test procedures can be bettered by the careful adherence to consistent guidelines, administration of tests by trained professionals, and subsequent retests performed by the same examiner. Test result should be document and address the type(s) of sensation affected, the quantity, degree of involvement, and localization of the exact boundaries of the sensory deficits.
Finally, it should be highlighted that additional research related to sensory testing is justified. Further development of Quantitative Sensory Testing (QST) techniques, standardized protocols, reliability measures, and additional normative data will significantly better the clinical applications of data obtained from the examination of sensory function.
An important component of physical therapy intervention is to accurately and efficiently meet individual patient needs. Together with information from the history and review of systems, screenings assist the therapist in proficiently identifying the needed tests and measures and setting priorities within the examination process.
Screenings comprising of a series of brief tests that provide the therapist an “overview” of the system of interest (e.g., musculoskeletal, neuromuscular). There are various screening methods available as below:
1. VIBRATION
Tuning forks are made of steel or magnesium alloy and grossly resemble a two-pronged fork. When the tines are stuck against a surface (usually the palm of the examiner’s hand) the fork resonates at a specific pitch (e.g., 128, 256, or 512 Hz) determined by the length of the two U-shaped prongs (tines).
Bio-thesiometer instrument is designed to quantitatively measure threshold perception of a vibratory stimulus. The stimulus is applied using a handheld device applied to the skin. Intensity of stimulation can be preset or gradually increased until the threshold is reached (or gradually lowered until no longer felt).
Vibrameter also quantitatively measures the perception of vibration. Standardized test points have been identified for use with this instrument. The test points (e.g., dorsum of the metacarpal bone of index finger, first metatarsal, and on tibia) allow for ease of comparison and interpretation of results. The sites also represent relatively long neural pathways for transmission to the CNS (Central nervous system). Stimulus is applied using the handheld device. Handheld transducers are used to apply the stimuli. Patient responses are recorded using a handheld pushbutton device or a continuous electronic Visual Analog Scale (VAS). During examination, data are automatically stored in a computer database.
2. PRESSURE
The therapist’s fingertip or a double-tipped cotton swab is used to apply a firm pressure on the skin surface. This pressure should be firm enough to indent the skin and to stimulate the deep receptors. This test can also be administered using the thumb and fingers to squeeze the Achilles tendon. Response of patient is asked to indicate when an applied stimulus is recognized by responding “yes” or “no.”
3. TEMPERATURE
Temperature Awareness, this test determines the ability to distinguish between warm and cool stimuli. Two test tubes with stoppers are required for this examination; one should be filled with warm water and the other with crushed ice. Ideal temperatures for cold are between 41°F (5°C) and 50°F (10°C) and for warmth, between 104°F (40°C) and 113°F (45°C). Caution should be exercised to remain within these ranges, because exceeding these temperatures may elicit a pain response and consequently inaccurate test results. The side of the test tube should be placed in contact with the skin (as opposed to only the distal end). This technique provides sufficient surface area contact to determine the temperature. The test tubes are randomly placed in contact with the skin area to be tested. All skin surfaces should be tested. Response of patient is asked to reply hot or cold after each stimulus application.
Tip Therma is an early detection tool for identification of changes in thermal perception designed for monitoring Polyneuropathies associated with diabetes. It provides a method for patients to test temperature sensitivity of their feet independently. It provides only a gross estimate of temperature perception; however, its convenience, low cost, and patients’ ability to use it are important characteristics. The tool can be used many times, requires no energy, and makes use of the special characteristics of synthetic material and metal. One end is metal and the opposite side is synthetic material. Both materials are essentially at room temperature; however, the metal end takes more heat from the body (metal has a higher conductivity than the synthetic end). As a result, the metal end is perceived as warm and the synthetic end as cooler.
The Tip Therma is a thermal instrument designed for patient monitoring of gross temperature perception of the feet. The instrument is 4 inches (100 mm) long with a .59-inch (15 mm) diameter.
In this fast-growing world of health science at present, there is no formula or scale which identifies sensory changes in diabetes subjects. Era of evidence-based practice and clinical reasoning is emerging day by day. Technology is moving ahead day by day, leaving us all confined in splendor and comfort with a lot of unknown harmful side effects on health. Clinician can initiate early intervention by educating patients on the dos and don’ts for prevention and modification. To provide a proper education for subjects with Diabetes Mellitus which emphasis on daily inspection of the feet, implementation of the appropriate level of weight bearing activities, selection of proper footwear, check sensitive pressure area and improve overall expectances of life.
So, it becomes of utmost importance that there should be some objective criteria to evaluate sensory changes in diabetes subjects and its analysis by normative reference value of normal individual. Hence, the present invention is solving this problem by developing sensory device.
The present invention address to physiotherapy care device, the evaluation of sensory function stands as a cornerstone in the diagnostic and therapeutic process. Understanding the nuances of sensory perception not only aids in diagnosing underlying conditions but also guides the formulation of effective treatment plans and prognoses. Traditionally, sensory evaluation has relied on subjective assessments and rudimentary tools, leading to limitations in accuracy and reliability.
The present invention represents a significant advancement in the field of physiotherapy, with the potential to elevate standards of care, improve patient outcomes, and contribute to the ongoing evolution of rehabilitative medicine.

Procedure of study:
1. Michigan Neuropathy Screening Instrument (MNSI)
For all assessments, the foot should be warm (>30°C).
Foot Inspection: The feet are inspected for evidence of excessively dry skin, callous formation, fissures, frank ulceration or deformities. Deformities include flat feet, hammer toes, overlapping toes, halux valgus, joint sublaxation, prominent metatarsal heads, medial convexity (Charcot foot) and amputation.
Vibration Sensation: Vibration sensation should be performed with the great toe unsupported. Vibration sensation will be tested bilaterally using a 128 Hz tuning fork placed over the dorsum of the great toe on the boney prominence of the DIP joint. Patients, whose eyes are closed, will be asked to indicate when they can no longer sense the vibration from the vibrating tuning fork. In general, the examiner should be able to feel vibration from the hand-held tuning fork for 5 seconds longer on his distal forefinger than a normal subject can at the great toe (e.g. examiner’s DIP joint of the first finger versus patient’s toe). If the examiner feels vibration for 10 or more seconds on his or her finger, then vibration is considered decreased.
A trial should be given when the tuning fork is not vibrating to be certain that the patient is responding to vibration and not pressure or some other clue.
Vibration is scored as:
1) Present if the examiner senses the vibration on his or her finger for < 10 seconds,
2) Reduced if sensed for = 10 or 3) absent (no vibration detection.) Muscle Stretch Reflexes: The ankle reflexes will be examined using an appropriate reflex hammer (e.g. Trimmers or Queen square).
The ankle reflexes should be elicited in the sitting position with the foot dependent and the patient relaxed. For the reflex, the foot should be passively positioned and the foot dorsiflexed slightly to obtain optimal stretch of the muscle. The Achilles tendon should be percussed directly. If the reflex is obtained, it is graded as present. If the reflex is absent, the patient is asked to perform the Jendrassic maneuver (i.e., hooking the fingers together and pulling). Reflexes elicited with the Jendrassic maneuver alone are designated “present with reinforcement.” If the reflex is absent, even in the face of the Jendrassic maneuver, the reflex is considered absent.
Monofilament Testing: For this examination, it is important that the patient’s foot be supported (i.e., allow the sole of the foot to rest on a flat, warm surface). The filament should initially be pre stressed (4-6 perpendicular applications to the dorsum of the examiner’s first finger). The filament is then applied to the dorsum of the great toe midway between the nail fold and the Distal Interphalageal joint. Do not hold the toe directly. The filament is applied perpendicularly and briefly, (<1 second) with an even pressure.
When the filament bends, the force of 10 grams has been applied. The patient, whose eyes are closed, is asked to respond yes if he/she feels the filament. Eight correct responses out of 10 applications are considered normal: one to seven correct responses indicate reduced sensation and no correct answers translates into absent sensation.
The MNSI questionnaire is self-administered. Responses are added to obtain a total score. ’Yes ‘responses to questions 1–3, 5–6, 8–9, 11–12, 14–15 is each counted as one point. ’No ‘responses to questions 7 and 13 each count as one point. Question 4 was considered to be a measure of impaired circulation and question 10 a measure of general asthenia and were not included in the published scoring algorithm. A score of = 7 was considered abnormal. All 15 questions were included in the new scoring algorithms. During the MNSI examination, a health professional inspects each foot for deformities, dry skin, calluses, infections and fissures. Each foot with any abnormality receives a score of 1.
Each foot is also inspected for ulcers and each foot with an ulcer receives a score of 1. The ankle reflexes are also elicited. If the reflex is absent, the patient is asked to perform the Jendrassic maneuver and, if present, the reflex is designated as present with reinforcement and is scored as 0.5. If the reflex is absent with the Jendrassic maneuver, the reflex is designated as absent and is scored as 1. Vibration sensation is then tested in the great toe using a 128-Hz tuning fork. In general, the examiner should be able to feel vibration in his or her hand for 5 s longer than a normal subject can at the great toe. Vibration is scored as present if the examiner senses the vibration on his or her finger for < 10 s longer than the subject feels it in the great toe, decreased if sensed for = 10 s (scored as 0.5) or absent (scored as. The total possible score is 8 points and, in the published scoring algorithm, a score = 2.5 is considered abnormal.
2. Inlow’s 60- second Diabetic Foot Screen tool
This tool is designed to assist in screening persons with diabetes to prevent or treat diabetes-related foot ulcers and/or limb threatening complications. The screen should be completed on admission of any person with diabetes and then repeated as directed by risk and clinical judgment. Patient may require frequent and regular visits for routine care but complete the screening as indicated or as relevant based on clinical judgment.
Specific Instructions:
Step 1: Explain screening to the patient and have them remove their shoes, socks from both feet.
Step 2: Remove any dressings or devices that impair the screening.
Step 3: Review each of the parameters for each foot as listed in the Inlow’s 60-second Diabetic Foot Screen and select the appropriate score based on patient’s status. (An amputation may affect the score on the affected limb.)
Step 4: Once the screen is completed determine care recommendations based on patient need, available resources and clinical judgment.
Step 5: Use the highest score from either the left or right foot to determine recommended screening intervals.
Step 6: Set up an appointment for the next screening based on screening score and clinical judgment
