    Evaluation of knee proprioception and effects of proprioception exercise in patients with benign joint hypermobility syndrome
    (SPRINGER HEIDELBERG, 2008) Sahin, Nilay; Baskent, Akin; Cakmak, Aysegul; Salli, Ali; Ugurlu, Hatice; Berker, Ender
    The first aim is to show if there is a disorder in proprioception in cases with benign joint hypermobility syndrome (BJHS) when compared to healthy subjects. The second aim is to evaluate the effect of proprioception exercise in BJHS cases. To evaluate the proprioceptive sensibility of the knee joint with 40 BJHS and 30 healthy subjects enrolled in the study. Then, cases with BJHS were randomized into two groups; proprioceptive exercises were applied to 15 patients for 8 weeks in clinic and 25 patients were taken as controls. Outcome measures included proprioceptive sensation, AIMS2 and VAS. Proprioception is significantly impaired in cases with BJHS. In BJHS group, significant decreases in VAS levels were detected in cases who did exercise compared with cases who did not, and statistically significant improvements were detected in occupational activity. For this reason proprioception exercises cause decrease in pain and improvement of functional status in BJHS group.

    Isokinetic evaluation of knee extensor/flexor muscle strength in patients with hypermobility syndrome
    (SPRINGER, 2008) Sahin, Nilay; Baskent, Akin; Ugurlu, Hatice; Berker, Ender
    Benign joint hypermobility syndrome (BJHS) is a syndrome with musculoskeletal pain originating from the increased laxity of the joints and the ligaments. The study was to compare the isokinetic strength of knee extensor/flexor muscles of BJHS patients with healthy controls. Forty patients diagnosed as having BJHS with Brighton criteria and 45 years of age, height and weight-matched healthy controls were recruited for the study. Isokinetic testing was performed with isokinetic dynamometry of Biodex System 3Pro and measurements were recorded at knee extension/flexion pattern concentrically at 60, 180, and 240/s angular velocities. The study group was also evaluated for functional impairment and pain by HAQ and VAS respectively. Knee extensor muscle strength was significantly lower in the patient group compared with the controls. It was hypothesized that the muscle weakness in the study group was related to lengthening of the quadriceps muscle and pain-related inactivity as well as joint instability and proprioception defect.

    MUSCULAR KINETICS AND FATIGUE EVALUATION OF KNEE USING BY ISOKINETIC DYNAMOMETER IN PATIENTS WITH ANKYLOSING SPONDYLITIS
    (PUBLISAUDE-EDICOES MEDICAS LDA, 2011) Sahin, Nilay; Ozcan, Emel; Baskent, Akin; Karan, Ayse; Kasikcioglu, Erdem
    Objective: Ankylosing Spondylitis (AS) is an inflammatory disease that is observed with arthritis, sacroiliitis and disability The aim of the study was to compare the strength and fatigue of knee extensor/flexor muscle group usage by isokinetic in patients with AS with controls. Methods: Twenty-six AS diagnosed patients and twenty-six healthy volunteers with similar age, height, body weight and gender were included in this study. In both groups the isokinetic tests are conducted by isokinetic dynamometer for every subject. Knee extension/flexion patterns;peak torque, agonist/antagonist ratio and work fatigue isokinetic parameters were evaluated during the knee 60 degrees/s, 180 degrees/s and 240 degrees/s angular velocities. Results: Knee extension/flexion muscle strength in patient group was significantly lower compared to the control group in all angular velocities (p<0.05). Conclusions: The study showed knee muscle weakness and fatigue in patients with AS compared to the control group.
