Clinical Trial Summary

The aim of this study is to examine whether Pulsed Electromagnetic Field therapy combined with strengthening exercises will have a positive effect on quadriceps muscle strength in lower limb burn .

Description:

• Subjects: Sixty patients with lower limb burn, subdivided into two groups each one has 30 patients.

• Group (A) = Pulsed Electromagnetic Field therapy and quadriceps strengthening exercises group.

• Group (B) = quadriceps strengthening exercises group. • Equipment and tools:

1. Measurements tools:

Isokinetic dynamometer : to measure the quadriceps muscle peak torque before the treatment and after 8 weeks of treatment for both groups.

2. Therapeutic tools:

Pulsed Electromagnetic Field therapy device and free weights for strengthening of quadriceps muscle.

• Lower Limb Burn

Intervention

Device:
• pulsed electromagnetic field device
the pulsed electromagnetic field device treatment parameters will be set as 15 Hz frequency, 20 gauss amplitude, and 20 minutes as total treatment duration.

Other:
• Free weights for Strengthening Exercise
• Parameters of the exercise program: Intensity : The weight or load the patients lifted is set at 50-60% of their individual 1RM , 3 sets of 10 repetitions during the first week. During the second week, the lifting load is increased to 70-75% (3 sets of 10 repetitions) of their individual 1RM and continued for weeks 2-6. After this, training intensity is increased to 80-85% of the 1 RM and implemented from weeks 7-8. Frequency: 3 sessions per week for 8 weeks. Number of repetitions: 3 sets,10 repetitions in each set. Total treatment duration: 8 weeks

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Isokinetic dynamometer for measuring The peak torque of the quadriceps muscle	Patients will warm up for 5 min on a cycle ergometer then quadriceps, hamstrings and calf muscles will be stretched 3 times with a 30 seconds stretch and a 30 seconds rest.; Patients will be positioned in an isokinetic dynamometer. The measurements are carried out with the backrest reclined 5° from vertical and knees flexed 90 degrees and straps fixing the trunk, waist and distal thigh. The rotation axis of the dynamometer is aligned with the axis of the knee joint at the level of the lateral epicondyle of the femur while it is attached to the distal part of the leg about 5cm above the medial malleolus and isokinetic test is performed at angular velocity of 150 degree per second.; For familiarization, Patients will perform a series of three submaximal contractions. After warming up, subjects are requested to perform ten maximal voluntary contractions consecutively without rest in between.; There will be three minutes of resting before repeating the test	8 weeks
