Rationale of the study
Diabetes mellitus is a non communicable chronic illness with
its prevalence increasing at an alarming rate in Thailand. The
prevalence of DM in Thai population increased from 4.4 in
year 1997 to 6.9 in 2009.
According to Thai DM association the incidence and rate (per
100000 population) of DM for year 2008 and 2009 were 5200,
2672.12 and 5677, 2916.37 respectively. The prevalence of
complication due to DM was 14.3% or 746 people.
Rationale of the study
Diabetic neuropathy is the most common complication found
in DM type 2 patients. its prevalence of 23% leading poor
quality of life for DM patients by its symptom and other
related complication due to neuropathy like wounds,
infection and amputation of leg. Diabetic neuropathy is also
second leading cause of leg amputation.
Rationale of the study
According to Thai clinical practice guideline for DM 2011, DM
patients should go through complete foot examination each
year to assess risk of neuropathy to prevent DM foot ulcer
and further complication, but due increasing number of DM
patients and limitations in time.
Rationale of the study
The screening processes are limited to patient’s symptoms of
neuropathy like “presence of numbness of feet”. There is also
a knowledge gap about the reliability about using patient’s
symptoms for screening of diabetic neuropathy.
Almost question that asked about the symptom such as “ Do
you have feeling at finger tip and feet tip ? ” but now no
research support or guarantee for diagnosis that use
symptom shown are reliability or correctly and suitable for
diagnosis enough.
Purpose of the study
1. To study the relationship between the sign and symptoms*of
peripheral numbness in Type2 diabetic patient and diabetic
neuropathy.
2. To study about the factors causing to diabetic neuropathy in
Type2 diabetic patient such as sex, BMI, duration, associate
disease, drinking , smoking and glucose level control.
(sign and symptoms* including numbness, decrease level of consciousness, burning pain or electric shock feeling)
Research questionPrimary research question
Can patient’s symptom be used for screening of diabetic
neuropathy ?
Secondary research question
Other factor such as Age, Sex , Onset and duration, BMI, Smoking ,
Drinking , Co-morbidity, Blood sugar control have effect for diabetic
neuropathy ?
(sign and symptoms* including numbness, decrease level of consciousness, burning pain or electric shock feeling)
Research QuestionsP (Patient or Problem)
Type2 diabetic patient who came for the screening test at Thaphoe primary care unit, diabetic clinic at Naresuan university hospital and Medical ward at Naresuan university hospital.
I (Intervention or Exposure)
Symptom of diabetic neuropathy
C (Comparison intervention)
Patients who have and don’t have symptoms of diabetic neuropathy
O (Outcome)
Result from screening Diabetic neuropathy at feet by monofilament
Methodology Study design Cross sectional study

Sources of information’s
History taking of patients.
10 g monofilament examination of patients
OPD files of patients.

Methodology
Research process (in order)
Planning and testing of research.
studying proper handling of 10 g monofilament and the
testing it with real patients. The test was carried out on 4
patients in medical ward at Naresuan hospital
contracting officials in Naresuan university hospital for
facilitating patients and places for research.
Methodology
Research process (in order)
contacting medical personals at Thaphoe PCU for
appointment with patients coming for diabetic neuropathy
screening.
Introduction, explanation about our research, signing of
agreement for research.
Asking patient risk factors for diabetic neuropathy
10 g monofilament examination of patients feet.

Odd Ratio
The ethics review confidentiality of patients information was maintained by
without using true name and keeping information within the research members.
patients were informed of the confidentiality measures before signing the research agreement’s.
patient don’t have financial benefit from this research but have the benefit of free screening of Diabetic neuropathy with 10 g monofilament. Monofilament examination procedure doesn’t have any risk and is not painful to the patient

Limitation and suggestion
1. we should have sample that follow by calculation formulas.
2. If possible, you should used the better standard test procedure for more accuracy result.
3. The test should be done in diversity people because this thesis was done in the hospital only and patient should be take care of themselves, so the information we got may be not match with fact.
Limitation and suggestion
4. We should used blood sugar control procedure and kept FBS/HbA1C then compare in each person for different result or not by 10g-monofilament
5. You should add special characteristic belong to each person in quiz. To let us know what clinical that effect with 10 g monofilament test and got result in positive
6. You should kept more information that relate with onset of clinical then compare to the duration from onset to the testing time was done.
