“…Interestingly, our MDC values are comparable to previous studies of BBS in stroke patients where a score difference of 7 is necessary to be 95% confident of a genuine change [34,35]. Although the 95% confidence level is the most common level in research, some authors believe that lower levels of confidence might be enough in clinical settings [29,34,36]. Hence, we also present the 90% and 80% levels of confidence to provide the clinician with more options when evaluating an individual patient's function and to pinpoint the difference of increasing statistical rigor.…”

Forty-two stroke patients (mean age 56+12 years) were independently assessed within a 48 hours window by two raters in different pairs (total raters = 4).Results. Weighted kappa analysis indicated good to very good agreement at item level (range 0.63-0.96). The relative and absolute reliability of the total score of MESUPES (maximum 58) was high according to the intraclass correlation coefficients (ICC=0.98) and the standard error of measurement (SEM=2.68). The MDC for three levels of confidence was calculated: A score change of 8, 7 and 5 is necessary for a MDC to have confidence of 95%, 90% and 80% respectively of a genuine change. Correlation between the MESUPES and M MAS was high (r s =0.87).Conclusions. The MESUPES shows high interrater reliability, and our study provides useful estimates of MDC for different levels of certainty. Additional research to confirm concurrent validity and to examine other psychometric properties of the MESUPES such as sensitivity is needed.

“…Total PL demonstrated the greatest reliability and smallest MDC, outperforming the other metrics significantly. The MDC is an important metric for clinicians to use (Donoghue et al, 2009). This metric provides an outcome measure for an intervention, or may be used to track deterioration in a condition, such as recurrent ankle sprain or Diabetes.…”

Main outcome measures:Balance tasks were double leg stance, tandem stance and single leg stance with eyes open and closed. Performance was measured by converting accelerations into path length (PL, length of the sway trace), jerk (jerkiness of sway trace) and root mean square (RMS) of the accelerations.Results: Within-day ICC for PL were excellent (mean 0.78 95%CI 0.68-0.89), with Jerk and RMS demonstrating means of 0.60 and 0.47 respectively. The mean percentage minimal detectable change (MDC) within-day were small for PL (mean 6.7%, 95%CI 5.3-8.1).Between-day ICC were good for PL (mean 0.61, 95%CI 0.50-0.71), but more varied for Jerk and RMS. The mean percentage MDC was small for PL (mean 6.1%, 95%CI 5.0-7.2). No significant differences were determined for measurements between-days for any metric or task. PL had the highest discriminatory value between the 8 tasks. Conclusions:The sacral mounted accelerometer reliably measured balance performance within-and between-days. The PL is the recommended metric as it was the most reliable, most discriminatory and most sensitive to change.

“…The 90% confidence level is acceptable when decisions regarding effectiveness of intervention are concerned (Haley & Fragala-Pinkham, 2006;Portney & Watkins, 2009). The calculation of an MDC value is important for clinical decision making, increasing clinical application and bridging the gap between evidence and practice (Donoghue et al, 2009).…”
