About

The goal of this clinical trial is to learn if a high intensity magnetic field is an effective way to treat quadriceps muscle atrophy after knee arthroscopic surgery in adult patients. The main questions it aims to answer are:

Is high intensity magnetic field muscle stimulation is an effective way to treat quadriceps muscle atrophy Is high intensity magnetic field muscle stimulation is more effective and more tolerable option for quadriceps muscle stimulation than transcutaneous muscle electrical stimulation Researchers will compare high intensity magnetic field muscle stimulation to transcutaneous muscle electrical stimulation and control group, to see if high intensity magnetic field muscle stimulation works to treat quadriceps muscle atrophy.

Participants will:

receive high intensity magnetic field or transcutaneous muscle electrical stimulation 1 time/day for 14 days, Visit the rehabilitation department for testing before/after and 1 month after rehabilitation.

Full description

The purpose of this study is to evaluate the effectiveness of quadriceps muscle stimulation methods: transcutaneous neuromuscular electrostimulation (standard methodology) and high-intensity magnetic field (innovative methodology) stimulation in the rehabilitation of patients after arthroscopic knee surgery, and the impact of the applied methods on the quality of life.

Objectives:

1. To evaluate and check the quadriceps muscle volume, strength, knee joint motion amplitude, pain intensity before and after outpatient rehabilitation and to identify factors that may influence their occurrence.
2. To evaluate and compare the effectiveness of transcutaneous neuromuscular electrical stimulation and high-intensity magnetic field stimulation on changes in quadriceps muscle volume and strength in patients undergoing outpatient rehabilitation after knee joint arthroscopic surgeries.
3. To evaluate the impact of quadriceps muscle size and strength reduction on movement function and quality of life during outpatient rehabilitation, to evaluate changes in condition after outpatient rehabilitation and the previous 1 month, to compare the results obtained.
4. To establish and compare the tolerance of different muscle stimulation methods used and possible adverse reactions after arthroscopic knee joint surgeries.

Subject of the study:

Patients undergoing outpatient rehabilitation, according to the profile of musculoskeletal injuries, 14 days.
