Impaired lower extremity muscle strength was observed in chronic venous insufficiency patients. Although the current study was consistent with literature in respect of impaired calf muscle strength, this finding was also seen in the thigh muscles. Furthermore, we concluded that if venous insufficiency becomes more severe, impaired calf muscle strength becomes more evident.

ObjectiveWhether surgical or conservative treatment is more effective in allowing patients to return to physical activity after anterior cruciate ligament (ACL) injury is controversial. We sought to compare mid-term outcome measures between isolated ACL tear patients who underwent reconstruction followed by closed kinetic chain exercises and those who underwent neuromuscular training only.MethodsWe retrospectively evaluated patients with ACL tears who underwent post-surgery CKC strength training after ACL reconstruction (Group A), and patients who only underwent neuromuscular training (Group B) with a minimum follow-up time of 5 years. Surgical techniques, rehabilitation, assessment of subjective knee function, one-leg hop test, assessment of joint position sense, muscle strength, and the health profile of the patient were evaluated.ResultsOverall, 43 patients were included in Group A (mean age, 32.56 ± 4.89; Tegner activity scale, 5) and 39 patients in Group B (31.67 ± 7.27; 5). Patients in both groups returned to their regular physical activity level after a similar time frame (Group A: average, 12 months; Group B, average, 13.4 months). The mean Lysholm knee score was 88.52 ± 7.65 in Group A and 86.21 ± 13.72 in Group B. Mean distances for the one-leg hop test for Group A were 135.21 ± 31.66 and 145.36 ± 42.10 mm in the reconstructed and uninjured knees, respectively. In Group B, the mean hop distances were 132.47 ± 28.13 and 147.89 ± 21.45 mm in the rehabilitated and uninjured knees, respectively. No statistical difference was observed between the groups for any of the parameters evaluated, including assessment of subjective knee function, one-leg hop test, assessment of joint position sense, muscle strength, and the health profile.ConclusionOur data suggest that early surgical reconstruction may not be a prerequisite to returning to recreational physical activities after injury in patients with ACL tears.Level of evidenceLevel IV, therapeutic study.

Objectives: The purpose of this study was to evaluate the reliabilities of the Biosen C Line (BCL) laboratory and Lactate Scout (LS) hand-held portable lactate analyser within a wide range lactate concentration. LS analyser was compared to the BCL analyser (reference method) to evaluate its validity. Materials and methods: Blood samples were taken during an incremental treadmill test under laboratory conditions. In order to evaluate reliability, 99 blood samples with lactate concentrations changed between 0.8-11.1 mM were measured twice. Results: For the LS analyser, intraclass correlation coefficient (ICC) was 0.994; typical error of measurement (TE) and coefficient of variation (CV) were 0.200 mM and 2.95%, respectively. For the BCL analyser, ICC was 1.000; TE and CV were 0.044 mM and 0.50%, respectively. LS hand-held portable-and BCL laboratory analysers' reliability results show perfect accordance. In order to evaluate LS analyser reliability, 99 blood samples with lactate concentrations between 0.8-11.1 mM were also measured, giving a high validity coefficient of 0.976. Validity was also separately assessed for the three sample ranges of <2.5 mM, 2.5-5.0 mM and >5.0 mM, yielding ICC values of 0.862, 0.903 and 0.783, respectively. Comparing with the Bland & Altman method, LS and reference method mean lactic acid concentration difference was-0.097 mM, and limits of agreement-1.342 and 1.147 mM. Conclusion: The results of the study revealed that the LS analyser has high validity, however at concentrations higher than 5.0 mM, its measures are found significantly lower than those of the reference method.

Tanım: Lateral epikondilit dirsek ekleminin en sık görülen hastalıklarından biridir. Tekrarlayıcı ve güç gerektiren kol aktiviteleri risk faktörüdür. Lateral epikondilit tanılı hastalarda el bileği ekstansör kas kuvvetinin azaldığı bilinmektedir. Gereç ve Yöntemler: Çalışmaya lateral epikondilit tanısı ile ekstansör karpi radialis brevis kasına artroskopik gevşetme yapılan 8 hasta alındı. Cerrahi tedavi sonrasında bir yılı tamamlayan hastaların el bileklerine izokinetik dinamometre ile fleksör ve ekstansör kas kuvveti ölçümleri yapıldı. Bulgular: Hastaların el bileği fleksör ve ekstansör kas kuvvet ölçümlerinde istatistiksel açıdan anlamlı fark saptanmadı (p>0.05). Sonuç: Bu çalışmada lateral epikondilit tanılı hastalarda, ekstansör karpi radialis brevis kasına yapılan artroskopik gevşetmenin el bileği fleksör ve ekstansör kas kuvvetine olumsuz bir etkisi olmadığı gösterilmiştir. Anahtar Sözcükler: Lateral epikondilit; el bileği kas kuvveti; izokinetik. Investigation Of Wrist Flexor/Extensor Muscle StrengthFollowing Arthroscopic Surgical Treatment Of Lateral Epicondylitis ABSTRACT Objective: Lateral epicondylitis is a common disease of elbow joint. Repetitive wrist activities and activities that requires strength are risk factors. Wrist extensor muscle strength are decreased in patients with lateral epicondylitis. Materials and Methods: Eight patients with a diagnosis of lateral epicondylitis enrolled to study. Wrist flexor and extensor muscle strength of patients who were completed one year after surgery were measured by isokinetic dynamometer. Results: There were no statistically significant differences between the flexor and extensor muscle strength of the patients (p>0.05).
