An investigation of the reproducibility of a self-selected natural feet position when standing: Implications for the assessment of upright standing posture.

BACKGROUND: Photogrammetry is often used to evaluate standing static postural alignment. Patients are often instructed to self-select a natural feet position but it's unclear whether this position can be consistently replicated across repeated assessments. OBJECTIVE: To determine whether people can replicate a self-selected natural feet position in upright standing across three sessions on different days. DESIGN: Between days test-retest reliability. SETTING: University laboratory. METHODS: Three variables - Base of Support (BoS), Foot Width (FW), Feet Opening Angle (FOA) - were measured from foot tracings of 150 participants (18-30 years) using established procedures. BoS data were assessed for systematic bias (Analysis of Variance), and absolute (Coefficient of Variation - CV%) and relative (Intraclass Correlation Coefficient - ICC) reliability. RESULTS: There was systematic bias in the BoS data across the three testing sessions. The CV% for the BoS data was 15.2%. The ICC (95% CI) for the BoS data was 0.84 (0.79-0.87). There were moderate-large correlations between the BoS and both FOA and FW respectively within each session. CONCLUSION: If clinicians want to allow patients to use their self-selected natural feet position for repeated photogrammetric assessment of their static postural alignment it would be better to standardise the position of the feet, for example, by creating a tracing of a patient's self-selected natural feet position.

Factors influencing Australian chiropractors who choose not to join national professional associations: a qualitative study.

BACKGROUND: Professional associations (PAs) are perceived to promote their professions and support their members. Despite these advantages, about 1 in 3 Australian chiropractors choose not to belong to either of the two PAs. Our study had two objectives: 1) to explore the views of non-member chiropractors about PAs in general; 2) seek to understand the motivations of non-member Australian chiropractors about not joining a PA. METHODS: This qualitative descriptive study utilised in-depth semi-structured interviews with open-ended questions for thematic analysis and was conducted from January to April 2020. Nine participants were interviewed before no new themes were articulated. Participants had to be registered chiropractors who had not been members of a PA for at least three years. Recruitment was through a Facebook advertisement and snowball sampling. Interviews were transcribed and imported into NVivo qualitative analysis software, allowing identification of key concepts surrounding non-membership of chiropractic PAs. RESULTS: Five themes were identified. 1) A tarnished image, suggested the profession has a poor standing in the eyes of the public and other health professionals. 2) Not worth the money, expressed the annual membership dues were not viewed as good value for money. 3) Going it alone / what's in it for me? indicated there was no direct benefit or anything deemed essential for practice. 4) Two warring factions, reflected not wanting to be seen to be part of the internal conflict between conservative and evidence-based practitioners. 5) Lack of visibility, described no visible presence or strong communication that clearly displayed the advantages of membership. CONCLUSIONS: Non-members are looking for PAs to enhance the respectability of the profession in a manner that ultimately results in increased patient volume and the provision of readily accessible day-to-day resources and information. These results can inform the construction of a survey for the broader chiropractic non-membership community to confirm and expand upon these findings and potentially improve PAs.

Student performance on practical gross anatomy examinations is not affected by assessment modality.

Anatomical education is becoming modernized, not only in its teaching and learning, but also in its assessment formats. Traditional "steeplechase" examinations are being replaced with online gross anatomy examinations. The aims of this study were to: (1) determine if online anatomy practical examinations are equivalent to traditional anatomy practical examinations; and (2) to examine if students' perceptions of the online or laboratory testing environments influenced their performance on the examinations. In phase one, 10 third-year students were interviewed to generate perception items to which five anatomy lecturers assigned content validity. In phase two, students' gross anatomical knowledge was assessed by examinations in two modes and their perceptions were examined using the devised survey instrument. Forty-five second-year chiropractic students voluntarily participated in Phase Two. The two randomly allocated groups completed the examinations in a sequential cross-over manner. Student performance on the gross anatomy examination was not different between traditional "steeplechase" (mean ± standard deviation (SD): 69 ± 11%) and online (68 ± 15%) modes. The majority of students (87%) agreed that they felt comfortable using computers for gross anatomy examinations. However, fewer students found it easy to orientate images of cadaver specimens online. The majority of students (85%) agreed that they felt comfortable working with cadavers but there was less agreement on the effect of moving around the laboratory during practical examinations. This data will allow anatomists to confidently implement online assessments without fear of jeopardizing academic rigor or student performance.
