- 1) There will be no significant differences of the COG deviations between the patients group and the control group in the computerized force plate.
- 2) The age, height, and the weight do not have a significant meaning in the COG deviation.
제안 방법
- As a result, the measured values of the COG deviations showed a significant differences between the patients group and the control group. Further more, the correlations of the age, the height, and the weight with the COG deviation were tested to fmd out the effect of these variations on the COG. As a result of this correlations, 15.
- Since it is one dimensional evaluation, measuring a simple postural sway in a fixed surface, it cannot be either a good quality or good quantity evaluation of the postural control (Horak, 1987). However, the measuring equipment used for this study only can analyze the movements which occur in the coronal plane, side to side trajectory of the COG in the standing position, making impossible to analyze the actual three dimensional COG deviation. There weren’t many studies using the same equipment, making this study even harder to make the data quantitative statistically.
- All the studies showing the COG deviation present well how the body are oriented. The further, definite study of the COG deviation and large data should be quantified to use it as basic datas to evaluate the body. Therefore, more mechanical and the physiological relationships of the pain with the COG deviations should be studied further more.
- This can be easily accessed commercially. The instrument is computerized force plate which has the hardware with 2 load cell, amplifier, offset controller, AID (analog-digital) converter and the software, Mediance-I, Human Tech, Korea, which is the electrical posture-balance evaluation system having two module of the biofeedback and the evaluation. When the subjects step up to the frame which the load cells are attached, the weight of the subjects are measured and the graphs of the COG deviations are measured and displayed in the monitor.
- The instruments used in this study was originally used for the measurements of the COG deviations in the coronal plane of the statically standing person only, so this will not be perfectly accurate of measuring the COG deviations of a person moving in three dimensional way.
- However, the measuring equipment used for this study only can analyze the movements which occur in the coronal plane, side to side trajectory of the COG in the standing position, making impossible to analyze the actual three dimensional COG deviation. There weren’t many studies using the same equipment, making this study even harder to make the data quantitative statistically. To overcome these limitations, there should be a three dimensional analysis (anterior and posterior, side to side, up and down) of the COG deviations, and many other different groups of the patient, grouped by the disease/ diagnosis should be tested to make the data various.
- Therefore, this study looked at the relationships between the pain and the balance and the COG deviation of the normal 30 people and 71 people with musculoskeletal pain, using the computerized force plate. As a result, there were a significant differences between the groups.
- This study observed the COG deviation, the core of the postural maintenance and the balance ability, of the patients with the musculoskeletal pain and tried to find the effect of the musculoskeletal pain on the COG deviation by using the computerized force plate. This study tried a new approach to the effect of many different factors of the balance and the posture.

- This study was tried to find the effect of the musculoskeletal pain on the COG deviation which takes an important part in the posture and balance, using the computerized force plate.
대상 데이터
- For the subjects, 71 patients were selected who have a musculoskeletal low back pain and the shoulder pain without any history of the CNS lesions, COG affective orthopaedic problems of the lower extremities, or the vestibular and the visual default. For the control group normal and healthy 30 subjects were selected without any history of these COG affective disorders.

데이터처리
- 1) The student t-test was done to find out the differences of the COG deviations of the patients group and the control group.
- 2) The correlation test (Pearson correlation coefficient : r) was done to find out the relations of the age, height, weight and the COG deviation.
- The student t-test was done to find out the differences of the COG deviations of the subjects group and the control group. The result is as the Table 2.
- To find out the relations of the variations which can affect the COG deviation values, the correlation test of the age, the height, and the weight with the COG value were done and presented in the correlation coefficient (r) and p-value for the significance. The result is shown in Table 3.
성능/효과
- Further more, the correlations of the age, the height, and the weight with the COG deviation were tested to fmd out the effect of these variations on the COG. As a result of this correlations, 15.8% of the COG deviation was caused by the change of the weight, while the other variations didn’t show any significant relations. The pain affected the sensory integrations for the good posture and balance and its reacting process directly or/ and indirectly.
- As a result, the COG deviation values of the patients group was 2.56, and that of the control group was .83, showing 1.73 difference. This difference was significant statistically (p<.
- Increased COG deviation cause increased repulsive power of the plate, then these increase cause the posture changes, and this posture changes cause the muscle energy consumption increase. To find out the relations of the variations which can affect the COG values, the correlations of the age, the height, and the weight with COG were tested, and showed that 15.8% of the COG value was created by the weight. The other variations showed no significance with COG values.
후속연구
- This study was enforced even though there weren’t too many studies of the COG deviations on the patients with musculoskeletal pain, just to prepare a basic datas for the further studies in the nearest future.
