“…Although the reliability and validity of measures of physical function are established in older adults[ 23 , 24 , 28 , 31 ] these properties are not well described in cancer survivors and specifically not in older long-term survivors where impairments or limitations differ from those in the early stage of cancer survivorship let alone those without a history of cancer[ 5 , 9 ]. Therefore, the purpose of this study is to establish test-retest reliability, construct validity, and minimal detectable change of physical functional measures in a mixed group of older long-term cancer survivors.…”

Objective: To establish reliability, validity, and minimal detectable change in measures of function in older long-term cancer survivors. Methods: Older cancer survivors were recruited to perform functional measures; 5 Times Sit-to-Stand (5xSTS), 30-second Timed Chair Rise (30sTCR), Short Physical Performance Battery (SPPB), Physical Performance Test-7 (PPT-7). Two testing sessions were completed two weeks apart. Test-retest reliability was examined using the intraclass correlation coefficient (ICC 2,1 ), convergent and discriminant validity using Spearman’s rho and Minimal Detectable Change (MDC 95 ) was calculated. Results: Forty-seven older long-term cancer survivors participated. Test-retest reliability was good for 5xSTS (ICC 2,1 =0.86), 30sTCR (ICC 2,1 =0.89), and SPPB (ICC 2,1 =0.85) and poor for PPT-7 (ICC 2,1 =0.48). Both convergent and discriminant validity was established. Conclusions: SPPB, 5xSTS, and 30sTCR are reliable and valid tools to measure function in older long-term cancer survivors. MDC 95 values were larger than those reported in geriatrics and should be interpreted with caution. Residual effects of cancer treatment, comorbidity, and physical inactivity may contribute to decreased physical function in older long-term cancer survivors, therefore valid and reliable measures like SPPB and the timed chair rise tests should be used objectively measure function throughout the survivorship spectrum.

“…By 2017, Korea will be an aging society, with over 14.0% of its population being over 65 years old; by 2026, it will be a super-aged society, with the elderly accounting for over 20.0% of the population 1 ) . For this reason, gerontology research is becoming increasingly important, especially that centered on the measurement and evaluation of elderly health status 2 , 3 ) .…”

[Purpose] To verify, using Rasch analysis, the applicability of the 36-Item Short Form Health Survey (SF-36) to elderly Koreans, as this instrument would be useful for determining elderly individuals’ overall performance and providing them with health information. [Subjects and Methods] The SF-36 was administered to a sample of 510 individuals aged over 60 living in the Seoul and Gyeonggi areas of South Korea. When testing for goodness-of-fit, we considered items with infit and outfit indexes of over 1.30 or less than 0.70 to be incongruent. SF-36 factors that contained over three items, including physical functioning, role limitations (physical and emotional), mental health, vitality, and general health, were analyzed. Each factor was examined through step calibration of the response categories in the probability curve. [Results] The response categories were found to be appropriate because the adjustment values of each factor increased. We found five items in physical functioning, two items in role limitation–emotion, one item in mental health, and one item in general health to be incongruent; all items in the role limitation–physical and vitality factors were congruent. [Conclusion] We conclude that the SF-36 could be revised to more accurately measure the health status of elderly Koreans.

Effects of back extensor strengthening exercises on postural alignment, physical function and performance, self-efficacy, and quality of life in Japanese community-dwelling older adults: A controlled clinical trial

To examine the changes in postural alignment and kyphosis-correlated factors after 6 months of back extensor strengthening exercise in a group of community-dwelling older adults aged ≥65 years. Methods: We quasi-randomized 29 subjects into an intervention group treated with a back extensor strengthening program and a control group treated with a full-body exercise program. These groups completed 20-30 minutes of exercise directed by a physical therapist one or more times per week and were instructed to exercise at home as well. The participants were assessed prior to and after the intervention using the following criteria: postural alignment of "usual" and "best" posture, physical function, physical performance, self-efficacy, and quality of life. The differences between two factors (group and period) were compared for each of the measurement variables. Results: Subjects who adequately completed the exercises were analyzed. A reduced knee flexion angle was noted in the "best" posture of both groups, as were improved physical function and performance with the exception of one-leg standing time. Verifying the effect size in the post-hoc analysis, the body parts that showed changes to postural alignment after the intervention differed between groups. Conclusions: Back extensor strengthening exercises improved physical function and performance, but did not improve spinal alignment. The changes due to these interventions were not significantly different from changes observed in the full-body exercise group. However, post-hoc analysis revealed that the effect size of posture change was different, possible indicating that the two groups experienced different changes in the postural alignment.
