Abstract
Ankle sprains are among the most common athletic injuries. Even when treated, two third of the subjects experience it again. Physiotherapy is the chosen treatment for grade I & II ankle ligament sprains. Rehabilitation of such cases costs about two billion dollars a year in the USA. Inadequacy of the treatments and improper treatment protocols seem to be the main cause of recurrence. The present study was designed to compare the effects of conventional physiotherapy program with a new protocol concentrating on proprioceptive and balance training program. For this purpose 30 male subjects suffering from unilateral lateral ankle sprain, selected by convenience sampling, were recruited in the study and randomly allocated to 2 groups of 15. The first group received 10 sessions of conventional physiotherapy as suggested in the literature. The second group received 10 sessions of special proprioceptive and balance training protocol. Each group was tested before and after treatment. Both clinical and instrumented balance tests were performed in both groups to assess the dynamic and static aspects of their balance. Based on the obtained results, both groups were significantly better on all test items after treatment compared to before treatment. Subjects in the second group performed better in Limits of Stability test while standing on both legs as well as on the involved leg. The results also indicated that although both methods were effective in treating the patients, the protocol focusing on proprioceptive and balance training can be more successful in rehabilitation and faster return to the field of the injured athletes.

Abstract
Knee osteoarthritis causes joint laxity, muscle weakness and atrophy. These factors compromise neuromuscular protective mechanisms of the muscle, cause excessive joint loading and increase pain and disability. This condition also causes balance impairment which in this patients may be due to proprioceptive impairment and quadriceps weakness. The object of the present study was to compare the effect of muscle strengthening and neuromuscular training methods on therapeutic parameters improvement in patients with primary knee osteoarthritis. In this study 30 subjects with primary knee osteoarthritis(mean age 59.8, range 50-65) were divided non randomly into two groups and received training in two special therapeutic methods. An electrogoniometer was used for evaluation of propriception and biodex stability system was used for assessment of the balance. Pain and activity of daily living(ADL) levels of the subjects were assessed by using an extensive questionnaire. Based on the obtained results, both therapeutic methods appeared to be beneficial in therapeutic parameters improvement in patients with primary knee osteoarthritis(P<0.05) but the neuromuscular control method appeared to be more benifical(P<0.05).

Abstract
Knee is a common site of osteoarthritis possibly because it is often subject to trauma. Primary knee osteoarthritis has no known etiology while secondary osteoarthritis can be traced to abnormal joint mechanics. Actually, osteoarthritis may be a physiologic response to repetitive, longitudinal impulse loading of the joint. Knee proprioception derives from the integration of afferent signals from receptors in the muscles, tendons, joint capsule, ligaments, meniscal attachments and skin. Muscles and joint receptors are the major sources of joint propriception. In patients with knee osteoarthritis both muscle weakness and joint laxity cause proprioceptive impairment. Because of different roles of mechanoreceptors in detecting proprioception in different angles of joint, researchers decided to measure knee proprioception with active and passive reproduction angle methods in different joint angles of knee. The purpose of the present study was to determine 1) if proprioceptive acuity correlated with different knee angles, 2) if there was any significant difference between the measurements of active and passive reproduction angles. In this study 30 subjects with primary knee osteoarthritis(mean age 59.8, range 50-65) were selected through non probability sampling. An electrogoniometer was used for evaluation of proprioception. Also, knee joint proprioception was assessed with both active and passive reproduction angle techniques. Based on the obtained results, individuals with knee arthritis were significantly less able to detect terminal range of active and passive extension of knee than the initial range(P<0.05). The results also showed that there was no significant difference in the measurements of threshold for the detecion of active and passive motions.

Abstract
Background: One of the most important factors in the proper functioning of the military is the accurate assessment of feedback. Among these, the proper knee joint proprioception is one of the most important factors in this regard. This study was performed to evaluate knee joint proprioception changes in military forces following a period of a static and dynamic stretching of hamstrings, quadriceps and gastrocnemius muscles.
Methods: The study was semi-experimental. The population of the study included the men AJA air defense base of Khatam al-Anbia (PBUH), among which, 60 individuals were randomly divided into three groups of 20; Static (height: 173.27, Weight: 78.14), Dynamic (Height: 175.08, Weight: 76.92), and Control (Height: 176.12, Weight: 80.09). The subjects in both groups of static and dynamic stretching performed their group-specific stretching programs. The goniometric method of digital images was used to measure the knee joint proprioception using AutoCAD software. One-way variance analysis test and paired t-test were used for results. The significance level in the present paper was considered to be 95% (α≤0.05) (SPSS 22).
Results: The results of the knee joint proprioception variables showed a significant difference with the control group (slight increase), between the static groups (decrease, p=0.05) and the dynamics (decrease, p=0.004). There was also a significant difference in the measured variables in the in-group comparison in the static group (decrease, p=0323) and dynamics (decrease, p=0.002). (Reducing the absolute error values of the target angle reconstruction and, consequently, improving the knee joint propensity sensitivity).
Conclusion: Static and dynamic stretching exercises in the lower extremity can possibly affect muscle spikes, increase muscle temperature, trigger the activation phenomenon, repeat the movement in a specific pattern, and ultimately the phenomenon of post-traptional sensory drainage, increase the sensitivity of muscle receptors and ultimately improve the sense of knee joint condition. Since any proprioception sense of depression can lead to mechanical instability and ultimately cause the joint to be prone to mild blows and ultimately damage, stretching exercises may also change the muscle spindle properties and increase the knee proprioception. Also, dynamic stretching improves the ability to perform better in the knee joint proprioception variable relative to static stretchinglearning of nursing students as well as accepting responsibility professionals in medical sciences.
