Decline in muscle mass and muscle strength characterizes normal aging. As clinical studies show a relationship between high C-reactive protein (CRP) level and low muscle mass. The aim of this study was to investigate whether CRP level of inflammatory markers is associated with muscle strength in older persons by cross-sectional analysis with a sample 170 elderly men. We measured CRP levels, included isokinetic knee extensor strength and isometric back extensor strength among the subjects. Lower extremity strength (Isokinetic test) and lumber extensor muscle strength (Isometric test). From the result of this study, higher CRP level was generally associated with lower muscle strength and was significantly correlated with knee extensor strength and knee flexor strength (r=-0.353, r=-0.342, respectively). It was moderately correlated with lumbar extensor muscle strength (r=-0.233, p=0.05). After adjustment for covariates, higher CRP level was associated with knee strength and back extensor strength. Higher CRP level were generally associated with muscle strength in older men. Higher CRP level may contribute to the loss of muscle mass and strength that accompanies aging.

Calculating the estimated resting metabolic rate (RMR) in severely obese patients is useful, but there is controversy concerning the effectiveness of available predictive equations using body weight. This study compared the accuracy of four commonly used RMR predictive equations to measured RMR. We evaluated the efficacy of RMR equations against indirect calorimetry in forth female obese subjects. The subjects had their RMR measured by indirect calorimetry and compared to the most commonly used prediction equations (Harris-Benedict, Owen, and Mifflin-St Jeor, World Health Organization/Food and Agriculture Organization/United Nations University [WHO/FAU/UNU]). The results shows that Owen and Mifflin-St Jeor equations significantly under-estimated to our measured RMR. However, the WHO/FAO/UNU Equation was the most accurately predictive RMR values (1,543.6±110.3 vs. 1,484.3±218.3) compared to measured RMR. As based on data, we suggest that WHO/FAO/UNU equation and Harris-Benedicts equation would be most reasonable and useful for Korean obese women.

Reconstruction of the anterior cruciate ligament (ACL) restores knee stability. The remnant preserving technique was developed to preserve mechanoreceptor function, promote revasularzation and facilitate ligamentation. The purpose of this study was to analyze the clinical results of ACL reconstruction with remnant preserving. Between October in 2008 and September in 2009, 40 patients underwent ACL reconstruction using auto graft-hamstring tendon. On the basis of the ACL`s condition patients were divided into 2 groups. In the trial group (preserved remnant group, PRG; n=20), there were 20 males with an average age of 26.2 years. In the control group (no remnant group, NRG; n=20) were 20 males with an average of age 27.1 years. We measured concentric peak torque of the knee extensors and flexors at 60o/s and 180o/s on an Isokinetic dynamometry. Proprioceptive functions have been assessed using Joint position sense and threshold to detection of passive motion. Dynamic postural stability was measured as a stability index in the anterior-posterior and medial-lateral planes with the Biodex Stability System. All tests were measured post-operative 1year. We found significant difference between the PRG and NRG for Joint position sense at 15o (2.40o±1.00o vs. 3.36o±0.95o; p=0.0145) and threshold to detect passive motion at 45o (2.02o±0.59o vs. 3.12o±0.94o; p=0.0213). But, we found no significant difference between the groups for the test results of the dynamic postural stability and knee strength. Therefore, preservation of the remnant ACL reconstruction is helpful in preserving the proprioception and function to stabilize the knee.

The life situation has been changed in patients who underwent anterior cruciate ligament (ACL) rupture and subsequent reconstruction. The main purpose of this study was to assess the quality of life (QOL) of patients with ACL reconstruction through Short-Form 36 (SF-36) survey. And secondary aim was to investigate a relationship between health-related QOL survey and the correlation of results with other clinical test. 70 patients (age, 32.0±11.7 years) with an after 1 year ACL reconstruction participated in this study. As clinical evaluations, the SF-36 Questionnaire was used for the QOL and isokinetic strength test was performed for the knee extensors and flexors. And the anterio tibial translation was measured by KT-2000. Spearman’s correlation coefficient showed significant correlations between knee strength (extensor and flexor) deficit and SF-36 score including physical functioning, bodily pain, vitality, social function score (p<0.05). However, there was no correlation between SF-36 scores and mean ratio of anterior tibial translation (p>0.05). In conclusion, the Knee strength is significantly associated with QOL. Therefore after ACL reconstruction, a speedy recovery of muscular strength will help to improve the QOL.

Stress fractures are common injuries that begin with repetitive and excessive stress on the bone. It is very rare that stress fracture was occurred in pubis superior ramus in athletics, and the report concerning the exercise therapy for this fracture was not sufficient in the literature. We report of a case of a 17-year-old male soccer player who suffered from left inguinal pain due to the stress fracture of pubis superior ramus. He was conducted an exercise program that consisted of muscle strength, stretching, aerobic and functional exercise for 2 months. After this intervention, all muscle strength was significantly improved (17%) compared to baseline data, and also flexibility and range of motion were improved. This case shows that exercise therapy considered the cause and cyclic formation of bone remodeling is benefit to improve the exercise performance for a soccer player with superior ramus stress fracture.

To identify how influence preoperative predictable factors for knee function after one year of anterior cruciate ligament reconstruction (ACLR). The purpose of this study is to investigate the relationship of preoperative quadriceps strength and post-operative knee function scores (Lysholm score and International Knee Documentation Committee [IKDC] score) after surgery. We extracted seventy-one subjects who underwent hamstring autograft reconstruction to evaluate randomly. Muscle strength deficits were measured with CSMI isokinetic dynamometer. One year after ACLR, we collected these scores from subjects completed. After identification of baseline independent variables between quadriceps muscle strength deficits and both Lysholm score and IKDC score, we examined that how relevant influence in these relationship with these factors by classifying quartile groups. We demonstrated that quadriceps muscles strength and knee function scores were identified as significant correlation. It was compared with quartile outcome in order to analyze that how different result comes out as a degree of deficit. As a result, the only Q1 group who indicated less quadriceps muscle strength deficit (within 23% deficits) effected to knee function scores after one year surgery. The less of quadriceps muscle strength deficit indicated before surgery, the better functional knee score level turns up. Therefore, the result verified that there are significantly positive influences between these relationships after one year of ACLR.

The purpose of this study was to assess the knee strength and anterior laxity in between primary and revision anterior cruciate ligament (ACL) reconstruction. It was a cross-sectional study; 28 patients who had undergone revision ACL reconstruction and the another 30 patients who had primary ACL reconstruction once were compared each other which they all had been operated during the same period of season with the same technique in the same hospital. The isokinetic equipment was used to measure the main outcome for knee strength, and KT-2000 arthrometer was used for measuring anterior drawer test in 12 months post-reconstruction surgery. In the anterior drawer test, we found out that there were significantly differences between primary and revision ACL reconstruction groups (1.5±1.1 mm vs. 2.6±1.5 mm, p=0.001). There was no significant difference in the deficits of knee extensor and flexor muscle strength between primary and revision ACL reconstruction. Revision reconstruction groups have more laxity in anterior drawer than primary reconstruction groups. After revision ACL, the deficits of knee extensor and knee flexor muscle strength have no significantly difference from primary ACL reconstruction.
