Abstract
Background and aim: Cryotherapy has long been introduced as a common method for preventing and reducing edema caused by traumatic injuries. Many studies have been conducted regarding other effects of cold such as its effects on muscle strength which provided controversial results over the past decades. The aim of this study is to investigate whether cold is capable of changing the muscle strength.
Materials and methods: The research was conducted on 30 volunteers with the mean age of 22 years. In a standard situation, the volunteers were asked to make their maximum grip force. Cold was applied over their anterior forearm using an ice pack for 15 minutes. The maximum grip force was measured before and within 1 to 120 minutes after cold application.
Results:The strength of the anterior forearm muscles decreased rapidly after cold application. The maximum reduction of muscle strength, in average 18% was observed after 10 minutes. This was followed by a gradual increase of grip force. After 120 minutes the force was increased to about 5% above the baseline force that was before cold application.
Conclusion: Regarding the slight increase in the muscle strength and its long delay, cryotherapy of muscles cannot be considered as a practical method in rehabilitation of patients. However, this method would be of great importance for athletes.

Abstract
Background and aim: The great amount of load tolerated by the knee joint during daily activities has made this joint the most vulnerable joint to osteoarthritis. Different types of knee orthosis are prescribed for treatment and among them neopran and 3 pressure points orthosis are the most common ones. Although these orthosis are used widely, little is known about their effects on the relief of patient's symptoms. In this study the immediate effects of two "4 spring-loaded neopran" and "3 pressure points corrective" knee orthosis on the pain reduction and functional improvement of the patients suffering from medial compartment knee orthosis were compared.
Materials and methods: Twenty patients (age 53±12) with medial compartment knee osteoarthritis, with severity of less than grade 4 (based on the Kellgren & Lowrence grading method and diagnosis of an orthopedist) and tibiofemoral angle of above 180º were recruited. The functional performance was assessed by 6 min walking test in the first day without orthosis and in the 2nd and 3rd day immediately after wearing one of the orthosis in random order. The intensity of pain was evaluated by 100 mm VAS test in the first day before and after 6 min walking test and in the 2nd and 3rd day only after the walking test.
Results: Both orthosis induced a significant reduction in patient's pain (p<0.01) and improvement in functional capacity (p<0.01). the comparison between the two orthosis regarding the pain reduction after the walking test revealed the dominance of the 3 pressure points corrective orthosis (p<0.007). The difference between the functional improvements of two knee orthosis was statistically not significant (average increase in walking distance of 15 m and 24 meters for neopran and 3 pressure point orthosis).
Conclusion: The 3 pressure point and neopran knee orthosis can induce significant reduction in pain and improvement in the functional capacity of the patients with medial compartment knee osteoarthritis. The 3 pressure point orthosis seems to dominate the neopran in pain reduction and functional improvement (however not statistically significant).

Abstract
Background and aim: To investigate the effect of the light touch, vision and dual task interference on the surface electromyography (sEMG) activity of ankle muscles
Participants: Thirty persons (12 male, 18 Female), right hand without any neuro-musculo-skeletal disorder and in healthy condition, participated in this study.
Methods and Materials: Participants stood in upright and semi tandem position. There was a high sensitivity sensor on the right side in direction of femur greater trochanter. They should press the sensor less than 50 gr. Also we examined the rate of activity in 3 muscles (Tibialis Anterior, Proneus Longuse, Soleuse) on both lower limbs by Biometrix sEMG device. 4 positions were experimented in semi tandem standing: No Touch, No Counting No Touch, Counting Light Touch, No Counting Light Touch, Counting. Each of the above positions was tested in 2 conditions: Eyes Open, Eyes Closed.
Results: Our findings detect that light touch contact especially during vision, resulted in reducing the rate of sEMG activity in the leg postural muscles. No touch and closed eyes, raise the rate of sEMG activity to maximum.
conclusion: On basis of findings, it seems that following skin receptors stimulation, some complicated mechanisms will be begun and in order to the orders of Central Nervous System (CNS), these muscles will make the hole body, stable. So it can reduce the entered pressure on leg postural muscles. Therefore we can see the lesser rate in sEMG activity of leg postural muscles.

Abstract
Background and Aim: Osteoarthritis is the most common joint disease in adults around the world and plays a great role in inducing disability in elderly. Patients suffering from severe knee osteoarthritis usually complain of pain and severe functional disability. For these patients, conservative treatments are often induces least remedy for pain and improvement of functional ability. This study evaluates the effects of knee mechanical traction on pain, edema, range of movement and functional ability in patients with severe knee osteoarthritis. Materials and Methods: In this clinical trial, forty women with severe knee OA (grade 3 & 4 on the Kellgren-Lawrence grading scale) were recruited and randomly divided into two groups with different treatment protocols (common physiotherapy treatment and common physiotherapy treatment accompanied by knee traction). Functional capacity and level of pain were assessed by 6-minute walking test and visual analog scale respectively. A goniometer was used to measure knee range of movement and edema was also evaluated by use of measuring tape. Results: Common physiotherapy treatment accompanied by knee traction compared to common physiotherapy treatment leads to significant decrease in pain (P<0.01) and increase in functional capacity (P<0.05). Conclusion: Common physiotherapy treatment accompanied by knee traction is a more effective treatment than common physiotherapy procedure in patients with severe knee osteoarthritis.
