Summary

* Background Context: no studies have been identified to analyse the effect of real time feedback (using inertial sensors) on physiotherapy students learning the art of posterior-anterior thoracic manipulation (PATM). * Purpose: to study the effect caused by real-time feedback on the learning process for PATM, comparing two undergraduate physiotherapy student groups. Hypothesis: significant differences will exist in the execution parameters of manipulation among students receiving real-time feedback versus those who do not. * Study Design/Setting: longitudinal, pre-post intervention. * Patient Sample: Sixty-one undergraduate physiotherapy students were divided randomly into two groups, G1 (n = 31) (group without feedback in real time) and G2 (n = 30) (group with real-time feedback). * Outcome Measures: time, displacement and velocity and improvement (only between groups) to reach maximum peak, to reach minimum peak from maximum peak, total manipulation time. * Methods: two groups of physiotherapy students learned PATM, one using a traditional method and the other using real-time feedback (inertial sensor). Measures were obtained pre- and post-intervention. Intragroup pre- and post-intervention and intergroup post-intervention scores were calculated. An analysis of the measures' stability was developed through an ICC (1,2). * Results: the values of ICC ranged from 0.881 to 0.997. Statistically significant differences were found in all variables analysed (intra- and inter-group) in favour of G2. * Conclusions: the learning process for posterior-anterior thoracic manipulation is facilitated when the student receives real-time feedback.

Interventions

Type	Name	Description
DEVICE	Real Time Feedback	Before beginning practice, one of the teachers performed the manipulation and explained the graph parameters as real-time feedback to consider when interpreting the graph, leaving the graphic as the benchmark execution
DEVICE	Traditional Learning Method	Two expert teachers in manual therapy provided indications and corrections to the group with a teacher - student ratio of 1:8.
