Abstract
The aim of the paper is to present the concept of isokinetic exercises, which was introduced by Hislop and Perrine in 1967 for the first time. No article was found in Polish literature that in consolidated way would discuss mentioned subject. Hence, in support to numerous foreign scientific reports, authors have decided to present the isokinetic exercise to Polish physiotherapists and medical doctors. Thisle et al define isokinetic exercise as dynamic muscle contraction with controlled and holded speed of movement (iso-steady kinetic-movement) performed with specific devices used to that kind of exercises. isokinetic tests are a very precise diagnostic tool that enable an estimation of degree of soft tissues damage. General use of isokinetic strength measurement in clinical practice is based on its obvious validity and reliability in qualification of state and neuromuscular function. Followers of isokinetic tests confirm that it gives possibilities of precise assessment of muscle properties as well as objectification of results. Results enable very precise diagnostic of tested muscles in different biomechanical conditions of performing movement. Tests allow functional muscle assessment through comparison of contralateral, ipsilateral work, with confrontation with corresponding data or with results in control groups. Moreover, graphical presentation of dependence between recorded parameters in every point of tested range of movement is possible. It favors isokinetics in using it to diagnostic in postinjured states of movement system. The areas of application and rules of performance isokinetic testing were described in this article. The main biomechanical parameters which are used in analysis of muscle dynamic properties were discussed additionally.

Abstract
Objective. To determine whether active rehabilitation program including both isokinetic and aerobic exercises in lower limb after burn is effective or not? Method. Forty patients with lower limb burn were randomly divided into two equal groups, Group A (active rehabilitation group): received guidelines protocol (range of motion exercise, massage, splinting, stretching) plus active rehabilitation program consisted of combined isokinetic and aerobic exercises, while Group B (control group): received guidelines protocol and aerobic exercises. Treatment program was applied for 12 weeks (3 sessions/week). Evaluation methods included Biodex isokinetic dynamometer (BID) for obtaining peak torque (PT) of quadriceps and hamstring strength assessment and Lower Extremity Functional scale (LEFS) for functional activity assessment of lower limb. All measures were gathered before the start of the study, and after termination of the trial (after 12 weeks).
Results. An increase in PT of quadriceps and hamstring was reported in both groups at the end of the trial, 32.69% and 25.7% respectively in group A, while 14.19% and 10.22% respectively in group B. The difference between both groups was statistically significant (p < 0.05). Also, there was a statistical improvement in LEFS score in group A compared with that of group B (p < 0.05), as the percent of improvement in group A and B was 72.9% and 38.91% respectively. Conclusion. Higher statistical results were achieved with active rehabilitation program illustrating the prominent effects of isokinetic exercises in lower limb burn in the term of improving leg muscles strength and functional activity.
