Does Computer-Assisted Femur First THR Improve Musculoskeletal Loading Conditions?
Table 2
Different sources of variance of the measurement chain and the studies in order to determine the standard error of mean.
| Research question | Source of variance | Study | Target parameter |
| Is the result obtained dependent on the mocap analyst? |
Mocap analyst | One healthy subject (S1), 1 gait analysis, evaluated 10 times by 3 different examiners: A (experienced), B (experienced), and C (not experienced) | Standard error of mean (SEM) of hrf-HRFSEM |
| How big is the influence of marker-placement on the results obtained? | Mocap—marker placement | One healthy subject (S1), 10 gait analyses, application of marker set in alternating manner by 2 analysts: A (experienced) and B (experienced) | HRFSEM |
| Is the method robust enough to produce repeatable results? | Measurement chain |
Three healthy subjects (S1, S2, and S3), 10 gait analyses, evaluated by 1 experienced analyst (A) | HRFSEM |
