Objectives. The aim of this study was to investigate the relationships between pain, disability, and radiographic findings in patients with knee osteoarthritis (OA).Patients and Methods. A total of 114 patients with knee OA who attended the physical medicine and rehabilitation outpatient clinic were included in this study. The diagnosis was based on the American College of Rheumatology (ACR) criteria for knee OA. Age, duration of disease, and body mass index (BMI) of the patients were recorded. Radiographic features on the two-sided knee radiography were assessed with the Kellgren-Lawrence scale. The severity of knee pain, stiffness, and disability were measured using the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC).Results. The mean age of the patients was 56.98 (±8.28) years and the mean disease duration was 4.14 (±4.15) years. Kellgren-Lawrence grading scale and age or disease duration were positively and significantly associated, whereas none of the WOMAC subscores were found to be related with Kellgren-Lawrence grading scale (). On the other hand, WOMAC disability scores were significantly associated with WOMAC pain and WOMAC stiffness ().Conclusions. Knee pain, stiffness, and duration of disease may affect the level of disability in the patients with knee OA. Therefore treatment of knee OA could be planned according to the clinical features and functional status instead of radiological findings.

To investigate the effect of vestibular rehabilitation exercises supported with virtual reality containing real-life environments on dizziness, static and dynamic balance, functional mobility, fear of falling, anxiety, and depression in elderly patients with dizziness. In this prospective randomized controlled study, 32-patients aged 65-years and older who applied to the otorhinolaryngology clinic with dizziness complaint randomly assigned to 2 groups. In Group 1 (n = 16), vestibular rehabilitation program, supported with virtual reality, and in Group 2 (n = 16), conventional vestibular rehabilitation program was applied 30-min a day, 5 sessions per week, 15 sessions in total for 3 weeks. Subjects were evaluated with The Vertigo Symptom Scale (VSS), Dizziness Handicap Inventory (DHI), Berg Balance Test (BBT) and Timed Up & Go Test (TUG), Falls Efficacy Scale-International (FES-I), Postural Stability Test (PST), Geriatric Depression Scale (GDS), Hamilton Anxiety Scale (HAS) at baseline, at the end of the treatment and 6-months after the treatment. Statistically significant improvements were seen in the DHI emotional subscale and TUG in Group 1 compared to Group 2 at the end of the treatment in elderly with dizziness (p < 0.05). Also, there were significant improvements in the VSS, all DHI subgroups, and total scores, BBT, HAS in Group 1 compared to Group 2 at the 6-months after the treatment (p < 0.05). The application of vestibular rehabilitation in a virtual reality environment can lead to additional improvements especially in dizziness symptoms, disability, balance, and mobility in the elderly with chronic dizziness.

To compare the efficacy of electromyography (EMG)-triggered (active) neuromuscular electrical stimulation (NMES) and passive NMES in enhancing the upper extremity (UE) motor and functional recovery of subacute and chronic stage stroke patients. Thirty-one hemiplegic patients were randomly assigned to active NMES (n=11), passive NMES (n=10), and control (sham stimulation) (n=10) groups. Each treatment regimen was applied five times per week for 45 min for 3 weeks. All of the patients performed the same neurophysiologic exercise program for 45 min five times per week for 3 weeks. Patients were assessed by the UE component of the Fugl-Meyer Motor Assessment (UE-FMA), the self-care component of the Functional Independence Measure (self-care FIM), the Motor Activity Log (MAL), goniometric measurements of active wrist and metacarpophalangeal joint extension, surface EMG potentials, grip strength, and the modified Ashworth scale in a blinded manner. Data were obtained before and at the end of the treatment. Participants were similar in all clinical and demographic features (P>0.05). All groups were comparable with respect to UE-FMA, MAL, self-care FIM, wrist and finger flexor spasticity, active range of motion (ROM), grip strength, and surface EMG potentials before treatment (P>0.05). The active ROM, grip strength, FMA, FIM, surface EMG potentials, and MAL: amount of use were significantly improved in the EMG-triggered NMES group compared with the controls (P0.05). Both active and passive NMES as adjuvant therapy in the neurophysiologic exercise program effectively enhanced the UE motor and functional recovery of stroke survivors.
