Musculoskeletal imaging authority, levels of training, attitude, competence, and utilisation among clinical physiotherapists in Nigeria: a cross-sectional survey

BACKGROUND: Direct-access physiotherapy practice has led to a global review of the use of differential-diagnostic modalities such as musculoskeletal imaging (MI) in physiotherapy. OBJECTIVE: To explore the MI authority, levels of training, attitude, utilisation, and competence among clinical physiotherapists in Nigeria. METHODS: This national cross-sectional study analysed a voluntary response sample of 400 Nigerian physiotherapists that completed the online version of the Physiotherapist's Musculoskeletal Imaging Profiling Questionnaire (PMIPQ), using descriptive statistics, Spearman's correlation, Mann-Whitney U, Kruskal-Wallis, and Friedman's ANOVA tests. RESULTS: Of the 400 participants, 93.2% believed that physiotherapists should use MI in clinical practice. However, only 79.8% reported having MI authority in their practice settings. The participants' median (interquartile range) levels of training =10 (24) and competence =16 (24) were moderate. Nonetheless, levels of training (χ2 [15] = 1285.899, p = 0.001), and competence (χ2 [15] = 1310.769, p < 0.001) differed across MI procedures. The level of training and competence in x-ray referral and utilisation was significantly higher than magnetic resonance imaging, computed tomography scan, ultrasonography, scintigraphy, and dual-energy x-ray absorptiometry, in that order (p < 0.05). There was a significant positive correlation between the levels of training and competence (rho =0.61, p < 0.001). The participants had a positive attitude =32 (32) and occasionally used MI in clinical practice =21 (28). CONCLUSION: Majority of the respondents believed they had MI authority although there was no explicit affirmation of MI authority in the Nigerian Physiotherapy Practice Act. Participants had a positive attitude towards MI. However, levels of MI training, competence, and utilisation were moderate. Our findings have legislative and curriculum implications.
