PURPOSE: The purpose of this study was to investigate the vital capacity and maximal voluntary ventilation in subjects with forward head posture (FHP). METHODS: Twenty-eight subjects participated in this study (normal 14, FHP 14) and were resident in B city. The mean age, height and weight of subjects was 22.80yrs, 169.36cm and 62.79kg. Subjects were asked to breath maximally for FVC and repeatedly for MVV during 12 seconds. The variables of data were collected as follows: Forced Vital Capacity(FVC), Forced Expiratory Volume in One Second(FEV1), FEV1/FVC, Maximal Voluntary Ventilation(MVV). Each trial was performed by 3 times and we used the means to analyze the data. The mann-whitney U test and independent t-test were used to compare the vital capacity between normal and FHP subjects. All statistical analyses were performed using SPSS 21.0 for window version and p-values less than 0.05 were used to identify significant differences. RESULTS: The FVC, FEV1, FEV1/FVC and MVV of FHP subjects were decreased more than that of normal subjects and the difference was statistically significant between two groups. CONCLUSION: The vital capacity of subjects with FHP was generally lower than normal subjects. This study shows that the vital capacity of subjects with FHP could be decreased due to the bad neck posture that weakens the respiratory accessory muscles of neck.

PURPOSE: According to advanced research, the effect of foot type on balance is 3 type. There are squared foot, morton’s foot and Egyptian foot. Above all, Morton’s foot accounts for 22% of people. The purpose of this study is to find the effect of Morton``s Foot on Balance Ability. METHODS: Twenty healthy woman participate in this study(Mean age:23.93; Mean height: 163.35; Mean weight: 56.20) . They doesn’t have musculoskeletal or neurogical disorder. Ten of participants have morton’s foot group, and another ten person are normal foot group. Measurment of balance was used by Balance trainer(BT4) and balance pad(AIREX). Data analyzed in 3 way ANOVA. RESULTS: In foot type and support type of variables, Morton’s foot was significant differences in C90 area and Velocity. There was no significant difference between foot type and visual condition. In support type and visual condition of variables, unstable support significantly decreased in Tracelength, C90area and Velocity. If we find out correlationship of foot type, visual condition and support condition, There didn’t have relationship each other. CONCLUSION: This study found that correlationship of foot type, visual condition and support condition. But, there are no significant differences. Nevertheless, These results will also be able to offer baseline data about Morton’s foot study in future.
