Background: Many patients live with long-term deficits in knee function after an anterior cruciate ligament reconstruction (ACLR). However, research is inconclusive as to which physical performance measure is most strongly related to long-term patient-reported outcomes after ACLR. Hypothesis: Quadriceps strength would be most strongly associated with patient-reported long-term outcomes after ACLR. Study Design: Cross-sectional study. Level of Evidence: Level 3. Methods: A total of 40 patients (29 female) consented and participated an average of 10.9 years post-ACLR (range, 5-20 years). Patients completed the Lower Extremity Functional Scale (LEFS), the International Knee Documentation Committee (IKDC) Scale, Knee injury and Osteoarthritis Outcome Score Quality of Life (KOOS QoL) and Sport (KOOS Sport) subscales, and the Tampa Scale of Kinesiophobia (TSK-17). Each patient subsequently performed maximal isometric quadriceps contraction, a 60-second single-leg step-down test, and the single-leg single hop and triple hop for distance tests. Multivariate linear and logistic regression models determined how performance testing was associated with each patient-reported outcome when controlling for time since surgery, age, and TSK-17. Results: When controlling for time since surgery, age at the time of consent, and TSK-17 score, maximal isometric quadriceps strength normalized to body weight was the sole physical performance measure associated with IKDC ( P < 0.001), KOOS Sport ( P = 0.006), KOOS QoL ( P = 0.001), and LEFS scores ( P < 0.001). Single-leg step-down, single hop, and triple hop did not enter any of the linear regression models ( P > 0.20). Additionally, TSK-17 was associated with all patient-reported outcomes ( P ≤ 0.01) while time since surgery was not associated with any outcomes ( P > 0.05). Conclusion: Isometric quadriceps strength and kinesiophobia are significantly associated with long-term patient-reported outcomes after ACLR. Clinical Relevance: These results suggest that training to improve quadriceps strength and addressing kinesiophobia in the late stages of recovery from ACLR may improve long-term self-reported function.

The 4-m gait speed (4MGS), a simple physical performance measure and surrogate marker of frailty, consistently predicts adverse prognosis in older adults. We hypothesised that 4MGS could predict all-cause mortality and nonelective hospitalisation in patients with idiopathic pulmonary fibrosis (IPF).4MGS and lung function were measured at baseline in 130 outpatients newly diagnosed with IPF. Survival status and nonelective hospital admissions were recorded over 1 year. We assessed the predictive value of 4MGS (as a continuous variable and as a binary variable: slow versus preserved 4MGS) by calculating hazard ratios using Cox proportional regression, adjusting for potential confounding variables. Receiver operating characteristic curves assessed discrimination between the multivariable regression models and established prognostic indices.Continuous 4MGS and slow 4MGS were independent predictors of all-cause mortality (4MGS: HR 0.03, 95% CI 0.01–0.31; p=0.004; slow 4MGS: 2.63, 95% CI 1.01–6.87; p=0.049) and hospitalisation (4MGS: HR 0.02, 95% CI 0.01–0.14; p<0.001; slow 4MGS: 2.76, 95% CI 1.16–6.58; p=0.02). Multivariable models incorporating 4MGS or slow 4MGS had better discrimination for predicting mortality than either the gender, age and lung physiology index or Composite Physiologic Index.In patients with IPF, 4MGS is an independent predictor of all-cause mortality and nonelective hospitalisation.

The purpose of the study was to examine the independent associations of each individual physical performance measure (i.e., grip strength, walking speed, repeated chair stands, and balance test) with subdomains of cognitive function and to determine predictors for each subdomain of cognitive function. A secondary data analysis was performed using a nationally representative middle-aged and older sample of hypertensive population. The findings showed that after adding all four physical performance measures, stronger grip strength was significantly associated with better visuospatial abilities, episodic memory, orientation/attention, and overall cognitive function. In addition, faster walking speed and faster repeated chair stands were strongly associated with better episodic memory and overall cognitive function, respectively. Because grip strength was significantly associated with several subdomains of cognitive functioning, it seems conceivable that increasing physical activity would improve both grip strength and cognitive function in patients with hypertension.
