“…These results suggest that information on unique characteristics such as sharp angles or asymmetrical shapes may be useful for recognizing the shapes of test pieces, being consistent with the results of the previous study (4). This was because the subjects easily differentiated the shapes of the test pieces in each group based on unique characteristics, providing a strong input that served as clues during the tests (4,26).…”

“…As a result, there were differences in the test scores depending on the shapes of the test pieces. In each group, the ratio of correct answers increased as the size of the test pieces increased because a large object has a wider contact area that a subject can feel, thus providing more sensory information (26). In addition, the ratio of correct answers was higher for test pieces with sharp angles, such as Nos.…”

Rehabilitation for dysfunctions of eatingand swallowing should be considered in terms of not only motor but also sensory function. Sensory information from a bolus in the mouth plays an important role in eating and swallowing. Therefore, this study investigated oral stereognosis in 184 healthy adults with normal eating and swallowing function in order to obtain normative data. Oral stereognosis was assessed by using 20 intra-oral test pieces with different shapes. The subjects manipulated the test pieces in the mouth and identified their shapes. At this time, the test scores and response times for answering were recorded. The results revealed differences in oral stereognosis depending on the age of the subjects and the test pieces employed. The younger group had higher test scores and shorter response times than the older group, except for comparisons between the 20s and 30s age groups. In addition, response time was negative correlated with test scores (r = −0.956, P < 0.001). These results indicate that oral stereognosis decreases with age.

Oral sensory function is essential for the successful performance of a range of ingestion. Although the perception of object size is important in determining the degree of manipulation, evidence suggests that people does not always perceive the size of the object in oral cavity accurately. The purpose of this study was to investigate the factors affecting the intraoral perception of object size. Twenty-three healthy young volunteers detected the size of cylinders inserted into oral cavity blindly and identified it from the reference set. The diameter of cross section varied from 10 to 14 mm in a gap of 1 mm and had three different temperatures (5, 36, 50 °C) in each. The perceived size was recorded, and the difference with the actual size was assessed. The required time for identification was also measured and compared between gender and between temperatures. The results demonstrated that the direction of size illusion was significantly affected by the required time for identification. Long manipulation led to overestimation, and short manipulation led to underestimation of object size irrespective of temperature and size. Gender was the other factor affecting intraoral size perception. The rate of overestimation was low in female participants comparing with male participants in this experiment, although the number of participants was limited. We therefore concluded that in order to detect the other factors affecting intraoral size perception, regulating oral manipulation time is indispensable.

“…This particular study and several other previous investigations represented that older participants are having comparatively less efficiency for stereognostic than the younger participants [8,11,12,22]. The present study investigates a comparative efficiency assessment between the middle aged and young participants.…”

We previously reported that senior aged people display reduced stereognostic efficiency of the tongue compared to the young adults, and suggested the feasibility of getting over this situation applying the training protocol mentioned by us. The same important issue to the development of therapy for decreased function is study on prevention of aging-dependent functional decline. Early prevention of the oral stereognostic ability decrement might be the better option while investigation of the issues should be considered during the early onset of the conditions in aged patients.This study was conducted to understand the efficiency of tongue's stereognostic characteristics for middle-aged people with a comparative understanding with young adults. This analysis related to tongue was conducted in 78 young adults (mean age: 24.5 years) and 33 middle-agers (mean age: 50.5 years). The method applied in this study contained 20 varied shaped test pieces in the oral cavity of the subjects. The observations revealed that most of the young adults were able to identify different shaped test pieces compare to the older participants (mean correct number of responses: 16.8 and 15.2, respectively; p<0.001). Depending on the shapes the test pieces were divided into six groups. It was found that misidentification of a piece by the young participants lead to selection of similar piece belonging to the same group. Selection of pieces from other group was almost nil. On the other hand, the older participants (middle-agers) also identified test pieces less often from separate groups. Differences in degree of decrease in the stereognostic ability between middle-agers and seniors whose ability was reported previously were also discussed.
