![]() ![]() The clinician can also use the MDC value. Applying these values to this patient, the clinician can be 90% confident that the patient's actual score falls within ☑1 points of the patient's score of 50. From a prior study 48 the SEM was calculated to be 6.7 ASES points, with the 90% confidence bounds of ☑1 points. ![]() For example, a patient completes the ASES and obtains a score of 50 out of 100. These values can be interpreted and applied in the clinical setting when making decisions about a patient's care. The SEM for most patient-reported outcomes measures that have been developed and tested for measuring outcomes of upper extremity disability are on the order of 7 to 11 points on a 100-point scale. The MDC indicates the error associated with multiple completions of the same scale (e.g., when the same patient completes a shoulder-specific scale at initial evaluation and at discharge.) 47 The SEM is used to ascertain the associated error when a patient completes a shoulder-specific scale one time. Two values are used to determine the amount of error associated with a patient's score on a self-report form-the standard error of the mean (SEM) and the minimal detectable change (MDC). Irrgang, in The Athlete's Shoulder (Second Edition), 2009 Measures of Activity and ParticipationĪ limitation of currently available patient-reported clinical outcome instruments is their relatively imprecise measurement. ![]() 85 Finally, ≥ 10 s to complete the 5TSTS predicted risk of disability (Sn = 0.49 Sp = 0.78 + LR = 2.23 −LR = 0.37). 84 The inability to complete the 5TSTS test was a marginal predictor of falls (odds ratio = 4.22) and a significant predictor of ADL- (OR = 24.70) and instrumental activities of daily living (IADL)-related disability (OR = 17.10) at 3-year follow-up. 82,83 Tiedemann found that a score of ≥ 12 on the 30-second STS in individuals older than 74 identified the need of further assessment for fall risk. 80,81 Sarcopenia and prefrailty are indicated if the 5TSTS takes 13 seconds or more (Sn = 0.86 Sp = 0.53 + LR = 1.83 −LR = 0.62). 63,79 Eight or fewer STSs in 30 seconds is related to the risk of developing mobility disability and frailty. 76–78 An MDC for the 5TSTS was 2.5 to 4.3s. Normative scores for both versions of the STS for community-dwelling older adults and for senior athletes (defined as someone over age 60 who participates in any sport competition) are listed in Table 7.4.
