Background: Anterior cruciate ligament reconstruction (ACLR) using the quadriceps tendon is an increasingly popular technique. Both partial-thickness quadriceps tendon (PT-Q) and full-thickness quadriceps tendon (FT-Q) graft depths are employed. Hypothesis/Purpose: This study was designed to assess isokinetic peak torque, average power, and total work during knee extension in patients with FT-Q or PT-Q grafts for ACLR. We hypothesized that both groups would show lower isokinetic values for the operated side, with greater deficits in the FT-Q group than in the PT-Q group. Study Design: Cohort study; Level of evidence, 3. Methods: A total of 26 patients who underwent ACLR with either an FT-Q or PT-Q graft were recruited between June 2021 and November 2021. Patients underwent isokinetic knee extension testing at > 1 year after surgery. Mixed repeated-measures analysis of covariance with least square difference post hoc testing was used to determine significant differences or interactions for all variables. Results: Peak torque was significantly lower for the operated limb than the nonoperated limb in the FT-Q group (mean difference [MD] ± standard error [SE], −38.6 ± 8.3 Nċm [95% CI, −55.7 to −21.5 Nċm]; P <.001; d = 0.90) but not in the PT-Q group (MD ± SE, −7.3 ± 7.7 Nċm [95% CI, −23.2 to 8.5 Nċm]; P =.348; d = 0.20). Similarly, average power for the operated limb was lower than that for the nonoperated limb in the FT-Q group (MD ± SE, −53.6 ± 13.4 W [95% CI, −81.3 to −26.9 W]; P <.001; d = 0.88) but not in the PT-Q group (MD ± SE, –4.1 ± 12.4 W [95% CI, −29.8 to 21.5 W]; P =.742; d = 0.07), and total work was lower for the operated limb compared with the nonoperated limb in the FT-Q group (MD ± SE, −118.2 ± 27.1 J [95% CI, −174.3 to −62.2 J]; P <.001; d = 0.96) but not in the PT-Q group (MD ± SE, −18.3 ± 25.1 J [95% CI, −70.2 to 33.6 J]; P =.472; d = 0.15). Conclusion: The FT-Q group showed significant deficits in the operated limb compared with the nonoperated limb for all isokinetic variables. In contrast, no significant differences were found between the nonoperated and operated limbs for the PT-Q group. [ABSTRACT FROM AUTHOR]

Objective: The objective of this study was to evaluate effects of a self-managed music-guided exercise intervention on muscle strength among intensive care unit (ICU) survivors. Methods We used a two-arm randomized-controlled trial. Following ICU discharge, eligible participants were assigned to one of two groups: music group (n = 13) or active control group (n = 13). The music group was taught to self-manage upper and lower extremity exercise movements by listening to an individualized music-guided playlist twice daily for 5 days. The active control group was provided an exercise brochure and advised to perform the same exercises at the same intervals. Dynamometers were used to measure muscle strength. T-tests and Weighted GEE models were used for testing the intervention effect between groups. Results Twenty-six subjects were enrolled. The mean age was 62.8 (SD = 13.8), 53.8% were male, 65.4% were Caucasian, and the mean APACHE severity of illness score was 59 (SD = 23.4). Reasons for ICU admission were mainly cardiac and medical. The music group showed significant improvements in handgrip, plantar flexion, leg extension, elbow flexion, and shoulder adduction strengths on left and right sides. Additionally, left and right leg extensor and left plantar flexor strengths showed significant post-differences, and small to moderately large effect sizes, between the music group and control group. Conclusion These findings suggest that a music-guided exercise intervention has the potential to improve muscle strength in ICU survivors and prevent further post-ICU deterioration in ICU survivors. Future trials should build upon these preliminary findings. [ABSTRACT FROM AUTHOR]

This study compared the effectiveness of two proprioceptive exercise programs for persons diagnosed with Parkinson's disease (PD). Thirty-three patients with mild to moderate PD were randomly assigned to a yoga meditation program (YoMed) or to an established proprioceptive training program (PRO). Both interventions included twice weekly sessions (45 minutes each), spanning a 12-week period. Outcome measures included: joint position sense (JPS45°, JPS55°, JPS65°) and joint kinesthesia (JKFlex and JKExt), the Tinetti Balance Assessment Tool (TIN), Falls Efficacy Scale (FES), Balance Error Scoring System (BESS), dynamic posturography (DMA and TIME) and the Timed Up-and-Go Test (TUG). Test administrators were blinded to group affiliation. Significant between-group differences favoring the YoMed group were observed for TIN (p = 0.01, d = 0.77) and JKFlex (p = 0.05, d = −0.72). DMA and TIME scores significantly improved for both groups, and no adverse events were reported. These findings indicate that the YoMed program is safe and effective for patients with PD. Researchers should continue to examine the clinical efficacy of mind-body techniques to improve movement control and body awareness in this population. [ABSTRACT FROM AUTHOR]
