Background & Objective: Burning is a general health problem and is also a global injury as well as a very serious sanitary issue in industrial and developing countries. In its severe form, burning can claim lives. It seems essential in every society to analyze burning, to study the causes of burning, treatment outcomes and the death rates, etc. to find proper preventive measures. Materials & Methods: In this cross-sectional study, the medical records of all patients who were hospitalized and finally deceased during the years 2002 and 2004 in Zare' teaching hospital, Sari, were examined. Some variables including the age span average, the degree and percentage of burning, patients' residence, gender, the cause of burning (i.e. boiling water, fire, acids and explosives), average hospitalization period, surgery and also the abundance of self – burning attempts were examined. Results: This study indicate that during these 3 years the total number of those who died from burns was 506 (23.4%). The residential places were in Mazanderan province (41.7%), Golestan province (41.4%), and Gilan province (10.2%). The abundance of burning ranges as below: The 2 and 3 degree of burning at 91.8%. Regarding the percentage of burns, 31.7% of abundance pertains to burning at 90% and more. The greatest external causes leading to burns are petrol, gas, and gas oil at 57.9%. Also, the percentage of burns does not have much influence on death rate among 50 – year – olds and older people. Conclusion: This study indicated that the importance of death between burned patient in special sex and age. To establish hospitals, some issues must be considered as: distance, transportation, route dangers, characteristics of area, existing epidemiological survey, and finally the epidemics and event statistics.

Background and Objective: Ankle instability is one of the most prevalent injuries among athletes. Biomechanical changes, sensory-motor impairments, and neuromuscular disorders have been reported in individuals with chronic ankle instability. The present study was conducted to compare the electrical activity of selected leg and thigh muscles during performing functional movements in female athletes with and without chronic ankle instability.
Methods: This case-control research was conducted on 40 female athletes in the age range of 18-30 years in two groups, including the case (with ankle instability, n=20) and healthy control (without ankle instability, n=20) groups. The electrical activity of selected leg and thigh muscles was recorded during three functional patterns, i.e., the overhead squat, overhead squat with heel lift, and single-legged squat, by electromyography apparatus. The investigated muscles consisted of the gastrocnemius medialis (GM) muscle, the gastrocnemius lateralis (GL) muscle, the tibialis anterior (TA) muscle, the fibularis longus (FL) muscle, the soleus (SO) muscle, the vastus lateralis (VL) muscle, the vastus mediali (VM) muscle, and the biceps femoris (BF) muscle.
Results: The activity of the VM, VL, BF, and TA muscles in the single-legged squat and the activity of the VM, VL, BF, SO, and TA muscles in the overhead squat showed a statistically significant increase in the case group compared to the control group (P<0.05). The highest difference in the muscle activity of the two groups was observed in the overhead squat with heel lift movement, which in this movement, except for the GL muscle, there was a statistically significant increase among all other muscles (P<0.05).
Conclusion: Functional movements culminate in increasing the electrical activity level of leg and thigh muscles in female athletes with ankle instability.
