This study will be conducted to investigate the effect of early multi-angle isometric exercise on muscle properties in post-burn patients.
Male and female patients aged 20 to 40 years
Patients diagnosed with acute burns.
Total Body Surface Area (TBSA) ranging from 15% to 30%, 2nd degree burn patients.
Medically stable patients.
Patients with third-degree burns requiring immediate surgical grafting at the assessment site.
Patients with associated fractures or neurological disorders.
Patients with severe cardiopulmonary instability.
Patients under mechanical ventilation.
Parallel
isometric exercise program
Other interventionisometric exercises targeting the affected muscle groups Lower limb muscles. Exercises will begin within the first week post-burn after medical stabilization, Isometric contractions will be performed at submaximal intensity (approximately 50-60% of maximum voluntary contraction).Each contraction will be held for 5-10 seconds followed by 10 seconds of relaxation. Each muscle group will perform 10 repetitions per set in addition to conventional physical therapy
conventional physical therapy
Other interventionConventional physical therapy programs include positioning, mobilization, range of motion exercises, stretching and splinting
muscle dynamic stiffness
The MyotonPro (Myoton AS Tallinn, Estonia) device will be used to assess muscle dynamic stiffness. it introduces an innovative and non-invasive approach for comprehensively characterizing the biomechanical and viscoelastic properties of muscles.The device is applied under constant preload (0.18 N) to pre-compress subcutaneous tissues, and it exerts a brief (15 milliseconds) mechanical tap at a pre-determined force (0.4 Newtons), followed by quick release, causing damped oscillations that are recorded by the testing probe. This device is portable, inexpensive, easy to use, and convenient for re-cording the biomechanical and viscoelastic stiffness of myofascial tissues relatively quickly.A higher dynamic stiffness indicates greater resistance to force application.
lower limb disability
The Lower Extremity Functional Scale (LEFS) is a patient-reported outcome measure which assesses the functional status of patients who have lower extremity conditions of musculoskeletal origin. The 20-item questionnaire inquires as to the degree of difficulty of performance of each of these activities on a 5-point Likert scale and a score of 80 represents an individula with normal functions
oscillatory frequency
The MyotonPro (Myoton AS Tallinn, Estonia) device will be used to assess oscillation frequency. it introduces an innovative and non-invasive approach for comprehensively characterizing the biomechanical and viscoelastic properties of muscles.The device is applied under constant preload (0.18 N) to pre-compress subcutaneous tissues, and it exerts a brief (15 milliseconds) mechanical tap at a pre-determined force (0.4 Newtons), followed by quick release, causing damped oscillations that are recorded by the testing probe. This device is portable, inexpensive, easy to use, and convenient for re-cording the biomechanical and viscoelastic stiffness of myofascial tissues relatively quickly.A higher oscillation frequency indicates higher muscle tone, while increased stiffness reflects greater resistance to force application.
muscle elasticity
the MyotonPro (Myoton AS Tallinn, Estonia) device will be used to assess muscle elasticity. it quantifies the dissipation of mechanical energy (damping) during natural oscillations of a muscle. lower values signify higher elasticity (i.e., better ability to recover from deformation), while higher values suggest lower elasticity.
