Background and Objective: Use of joint sound signals for diagnosis of knee joint disorders has been greatly welcomed since it is a non-invasive and inexpensive technique. In vibroarthrography (VAG), joint sound signals can be detected using a contact sensor over the skin surface of the joint during movements. This study aimed to investigate the capability of this method in diagnosis of knee osteoarthritis (OA). Materials and Methods: In this study which was the evaluatin of a diagonstic test, forty-four knees from 22 healthy and OA-diagnosed subjects were included in this study. A miniature potentiometer was placed on the patellar, medial and lateral sides of the knees and their VAG signals were recorded in a non-weight bearing (NWB) flexion/extension task. The average root mean square (RMS) of the signals were calculated and compared between the healthy and OA knees. Results: The findings of this study revealed more physiologic signals in healthy knees. OA-diagnosed knees showed less physiologic signals with some spikes among them. There was no significant difference between these two groups in terms of the total average RMS of the VAG signals. However, a noticeable difference was noted between the right and left OA knees. The left OA knees did not show significantly different RMS in the medial and lateral sites, however this finding was significantly different on the patellar site compared to the left healthy knees (p=0.03). Conclusion: Based on these findings, the VAG technique might be considered as a non-invasive method in diagnosis of OA changes of the knees. It was also concluded that use of potentiometer on the patella is possibly helpful in diagnosis of only left knee osteoarthritis. Key words: Knee Osteoarthritis, Vibroarthrography, Non-invasive

Background and Objectives : Osteoarthritis is the most common arthicular disease of human. Medical managements of this disorder are mostly limited to relieving pain usually by NSAIDs. However, due to many
side effects of these medications, especially on elderly patients, long-term therapy with these drugs is of major concern. In this study, the analgesic effect of carbamazepine on knee osteoarthritis was compared with diclofenac as a NSAID and placebo.
Materials and Methods: In this double-blind randomised clinical trial study, 60 patients diagnosed with knee osteoarthritis were investigated for 12 months. The patients were then categorised into three groups carbamazepine, diclofenac, and placebo groups. After two weeks of treatment, the pain relief rate was re-evaluated for each patient using Visual Analogue Scale (VAS) . The data was then analysed using Chi-Square test.
Results: Patients categorised as carbamazepine and diclofenac groups showed a marked pain relief after treatment period compared to the placebo group (p<0.05 vsp= 0.12 respectively). However, the analgesic effect of carbamazepine was not significant compared to diclofenac.
Conclusion: Carbamazepine has a same analgesic effect on knee osteoarthritis as NSAIDs. So, it may be a favorite alternative to NSAIDs in patients who are not able to tolerate the detrimental effects of these drugs.

Background and Objectives : Physical activities have been recently recommended for the prevention of some chronic diseases such as osteoarthritis. However, the detrimental effects of severe physical activity on musculoskeletal system of athletes are still under debate. The current study aimed to compare the following parameters between retired professional athletes and non-athletic persons radiographic grading scales of osteoarthritis of the knee joint, arthralgia, musculoskeletal dysfunctions during excercise , daily living or recreation activities , and life quality.
Materials and Methods: In this cross-sectional study, 60 retired professional sportsmen aged 50-65 years involved in football, wrestling, and track and field sports with the same number of age-matched non-athletic controls were included. The participants were then divided into four equal groups of 15. The gathering data tools were as follows Clinical diagnosis and radiological findings confirmed by an orthopedic surgeon . The globalized and localized questionnaire of Knee injury and Osteoarthritis Outcome Score (KOOS) was used as the data gathering tool. Analysis of variance (ANOVA) and post Hoc (Tuky) test were used to analyze the data.
Results: The four above-mentioned groups had a significant difference regarding the following parameters radiographic grading scales of the knee osteoarthritis (p=0.001), knee pain (p<0.001), symptoms (p<0.001), dysfunction in daily living (p<0.001) recreational activities (p<0.001) and quality of life (p<0.001). Groups of football, wrestling, track and field sports and non- athletic persons had a higher score than the average in radiographic grading scales of knee osteoarthritis respectively, while they possessed a lower score for the other variables.
Conclusion: Professional sports may cause a higher risk of knee osteoarthritis particularly in sports which required a combination of strength and endurance activities than the endurance only sports.

Background and Objectives: Recently, vibration has been used widely as a rehabilitation intervention for neuro-musculo-skeletal disorders. As, the knee osteoarthritis (OA) is a common joint disorder among the people, this study was designed to investigate the effect of quadriceps local vibration on the symptoms of knee OA in the female patients.
Materials and Methods : This randomised clinical trial was done on 34 female patients with unilateral or bilateral tibiofemoral OA (62 knee), who were randomly assigned to one of the vibration groups: (17 patients with 31 affected knee) or control (17 patients with 31 affected knee). The subjects in the control group received 15 sessions (5 weeks) conventional physiotherapy protocol , while the vibration group received the same conventional physiotherapy protocol plus local vibration training protocol over the quadriceps muscle of affected knee. Maximum torque of concentric contraction of quadriceps muscle at 30, 60 and 90 degree/sec, pain pressure threshold (PPT), active knee flexion range of motion (ROM) and the amount of knee effusion were measured before and after intervention and also after 4 weeks of follow-up period.
Results : After intervention, significant increase in the knee flexion ROM in the dominant lower limb (p=0.016) and reduced pain perception in the right leg (p=0.023) and in the left leg (p=0.019) were seen in vibration group , compared to control group, while no significant difference was found between the experimental and control groups in term of maximum torque of quadriceps and knee effusion.
Conclusion : Local vibration over the quadriceps muscle may improve knee joint ROM and reduce pain in patients with knee OA, while, no beneficial effect was found on other knee OA symptoms such muscle weakness and knee effusion.

Background and Objectives: Knee is affected to osteoarthritis more than any other joints. The aim of this study was to compare the effects of low power laser with %1 HcP in treatment of knee osteoarthritis.
Materials and Methods: This double blinded clinical trial study was performed in Fattemieh physiotherapy clinic of Rafsanjan during 2011-2012. Ninety patients who were suffering from osteoarthritis of knee were divided randomly into three equal groups. The first group received laser, the second group was treated by %1 HcP and the third group received placebo. Intensity of pain, improvement of movement and inflammation were assessed during 1st, 5th and 10th sessions. Pain intensity, movement and inflammation were evaluated by Visual Analogue Scale (VAS), goniameter and meter, respectively. Data were analyzed using two-way repeated measures ANOVA, followed by Tukey's multiple comparisons test.
Results: Findings showed that 10 sessions of laser can be more effective than %1 HcP in reduction of pain in state of rest and movement of knee osteoarthritis (p<0.001). In relation to knee joint movements, laser and %1 HcP were more effective than placebo (p<0.001), but they did not reveal any significant difference. Laser (p=0.421) and %1 HcP (P=0.713) were no more effective than placebo in reducing the inflammation of knee.
Conclusion: It can be concluded that 10 sessions of laser could be more effective than %1 HcP in reduction of pain of knee osteoarthritis, but in the improvement of movements both of them (laser and %1 HcP) could be effective.

Materials and Methods: This randomized single-blinded clinical trial was performed in Fatemieh Physiotherapy Clinic of Rafsanjan during 2016-2017. Sixty patients conflicted to osteoarthritis of knee were randomly divided into three equal groups (each group with 20 samples) . The first, second ,and third groups received EA, LLLT .and CT, respectively during 10 sessions. Intensity of pain, movement, and the time of 6 Minute Walking Test (6MWT)were assessed during the first, fifth, and tenth sessions and 1 month after the end of treatments. Pain intensity, movements ,and the time of 6MWT were evaluated by Visual Analogue Scale (VAS), goniameter ,and chronometer, respectively. Data were analyzed using two-way repeated measures ANOVA followed by Tukey’s multiple comparisons test and chi-square test.
Results: The findings showed that 10 sessions of EA was more effective than LLLT and CT in reduction of pain in knee osteoarthritis (p<0.001). Also in relation to knee joint movements, EA was more effective than LLLT and CT in this joint (p<0.001). The finding of this study showed that EA was more effective than LLLT and CT in increasing the time of 6MWT (p<0.001).
Conclusion: According to this study, it seems that during 10 sessions, EA might be more effective than LLLT and CT in reducing pain, improving movement ,and increasing the time of 6MWT inknee osteoarthritis.
