Detailed Description
Muscular strength and endurance are two important compatible parts of the body; for normal people to move, lift things and do day-to-day activities or athletic performance. Large number of studies have been carried out to elaborate the different factor that help in improving the muscular strength as well as the endurance combined with rehabilitation programs in order to promote muscle function and prevent the injury(Akinoglu & Kocahan, 2020; Chou & Binder-Macleod, 2007; Evetovich et al., 2001; Selkowitz, 1985; Snyder-Mackler et al., 1994; Ward et al., 2006). Strengthening and endurance training have been used frequently in varied rehabilitation protocols in order to improve the overall musculoskeletal performance.(Earl & Hoch, 2011; Gondin et al., 2011). Meanwhile, Isokinetic training and Neuromuscular electrical stimulation are frequently utilized in physical therapy.(Brown & Whitehurst, 2003; Chou & Binder-Macleod, 2007; Evetovich et al., 2001; Stone, 1997).
Russian current is one of the popular preferred Neuromuscular electrical stimulation as it has been advocated to increase muscle strength due to its high tolerance as well as minimum pain level provocation (Akinoglu & Kocahan, 2020; Gondin et al., 2011). Russian currents are alternating currents at a frequency of 2.5 kHz that are burst modulated at a frequency of 50 Hz with a 50% duty cycle. The widely and most popular training protocol used with Russian current is (10/50/10) in which the stimulus is applied for a 10-second "on" period followed by a 50-second "off" or rest period, with a recommended treatment time of 10 minutes per stimulation session. Russian currents are used mainly to generate a motor response, but it also has been investigated as an electro-analgesia type intervention. This training protocol is used mainly to generate a motor response, but it also has been investigated as an electro-analgesia type intervention.
Despite a lot of previous research regarding the Russian current; no studies are available in which suggest the most efficient carrier frequency for Russian current to strengthening the muscles and increase muscle with isokinetic training in the short term and the effect of different RC on the EIT by the quadriceps muscle. The aim of this study is directed toward investigation of those different Russian current carrier frequencies' effects on the quadriceps muscle isokinetic strength and endurance in addition to investigate the effect of different mode of RC on the EIT by the quadriceps femoris muscle. This study will include measurement for the knee torque and quadriceps muscle strength using Biodex system 3 that will be generated by different carrier frequency in addition to different RC mode, and investigate the relationship between those variables.

Experimental: Group1
training used Russian Current carrier frequency at 2500-Hz alternating current.

The patient will be placed in sitting position, hip at 90-degree flexion, knee at 60°, the upper body supported by the backrest, cross belt support the trunk and cross belt support the pelvis. The dynamometer rotating axis will be aligned with knee joint axis and the resistance lever arm will place in the distal leg above the malleolus. The angle of the joints adjustment considering the joint's range of motion and the device's user's manual, any movement other than the range of motion determined by the mechanical limit will be not allowed All electrical induced contraction will last 4 second each, with characteristics of 75 bursts; 4 second time on, 400 μs pulse width and 10 second time off. The greatest electrically induced torque by the quadriceps muscle at the maximum current output from the stimulator will be recorded for each subject to be used in data analysis. The same procedure will be done on the 3rd week and after 6th week.
