About this study
this study will be conducted to investigate the effect of TECAR Therapy on quality of landing, healing and Function in patient with Calf Muscle Strain.
Read the detailed description
Calf muscle strain is one of the most common muscle injuries in high-performance athletes and contributes to substantial player downtime because of its high mean time to return to sport and occurrence during critical periods in the competitive season. Published reports on lower-body muscle strain have provided frequent updates on the rehabilitation of high-profile muscle groups, such as the hamstring muscles, and improvements to calf strain management are seldom discussed despite the prevalence of these injuries in competitive sports. In this article, we discuss the diagnosis, treatment, outcomes, risk factors, and prevention of calf muscle strain in athletes.Transfer of Electricity-Capacitive and Resistive (Tecar) therapy is considered a special form of energy that uses frequencies between 300 KHz and 1 MHz and is characterized as a non-invasive high-frequency energy that awakens the body's natural ability to self-regenerate. Thus, it promotes the natural physiological processes of the tissue metabolically, transferring energy without introducing radiation from the external environment. TECAR therapy stands out as a promising yet underexplored modality. Its mechanism of action-utilizing both capacitive and resistive energy transfer-suggests a novel approach to addressing musculoskeletal injuries and pain. While preliminary studies and clinical applications hint at its potential advantages, such as improved tissue healing and pain relief, a comprehensive evaluation of the existing research is necessary to fully understand the role of TECAR therapy in rehabilitation

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
TECAR therapyOther
The TECAR intervention was administered to the calf muscle using the Zimmer devicein capacitive (CAP) mode for a duration of 20 min. The therapy was applied with the signal at a variable power with a maximum of 300 W. The frequency used was 500 kHz with an intensity of 40%. The intervention was standardized to a distal-to-proximal stroking rhythm with moderate pressure. For the TECAR intervention, the capacitive (CAP) mode at 500 kHz with 40% intensity and a maximum power of 300 W was chosen to optimize deep tissue heating and promote local blood flow and tissue recovery. The 20 min duration reflects protocols commonly used in therapeutic settings for muscle recovery and rehabilitation plus conventional therapy
conventional treatmentOther
the patients will receive stretching exercises of the gastrocnemius (straight leg) and soleus (bended knee), eccentric exercises for calf muscles, plus plyometric exercises.
| Study group | Role | What they receive |
|---|---|---|
| TECAR therapy | Experimental | Thirty patients will receive TECAR therapy combined with conventional treatment three times per week for 12 weeks. Receives: Other: TECAR therapy; Other: conventional treatment |
| conventional treatment | Active comparator | Thirty patients will receive conventional treatment three times per week for 12 weeks. Receives: Other: conventional treatment |
What is being measured
The primary outcome is the main question the study is designed to answer.
size of injury
ultrasonography device will be used to assess size of injury
Measured: up to 12 weeks
Secondary outcomes (2)
landing error score system
Landing Error Scoring System is a clinical tool used to assess jump-landing mechanics for the video from my jumb land aplication . the feet, ankle, knees, hip, trunk, shoulder, neck and head posture is assessed through the video. it is a 17-item . According to the performance sheet, the questions 1-15 are Yes/No questions that are rated as 0 or 1. The questions 16 are rated as 0, 1, and 2; 0 = soft, 1= average and 2= stiff. the question 17 are rated as 0,1,2; 0= excellent,1 average and 2= poor, so the total score ranges from zero to 19. A higher score indicates poor technique in landing from a jump; a lower score indicates better jump-landing technique. the score are categorized as excellent which less than 4, good score more than four and less than or equal 5, moderate score less than four and poor more than six
Measured: up to 12 weeks
jump height
The vertical jump test was performed as a one-legged counter movement jump (CMJ). Starting position was in an upright position with the hands placed behind the back. The subjects quickly bent the knee as much as desired and then immediately jumped upward attempting to maximize the height jumped. The subjects performed three maximal approved trials for each leg, starting with the right and alternating between the right and the left leg. However, if the subject increased hop performance in all three jumps, additional jumps were performed until no increase was seen. The best jump height for each leg was used for data analysis.
Measured: up to 12 weeks
