Brief Summary

Motocross, a popular sport, involves riding motorized vehicles on rugged tracks with obstacles. It's physically demanding, with high speeds and a risk of accidents. Grip strength is crucial, especially in the arms and forearms, which are prone to injury. Physiotherapy often employs strength exercises, including electromyostimulation. However, there's little research on their effectiveness for motocross athletes. This study aims to compare electromyostimulation combined with strength training versus strength training alone in relieving pain, fatigue, and improving strength in motocross athletes.

Outcome Measures

Primary Outcomes (4)

• Visual analog scale

  Pain assessment: Pain scores of patients will be recorded using 0-100 mm Visual Analog Scale (VAS) to grade pain. For VAS; A measured horizontal line will be created, and definitions such as 'no symptoms' and 'severe symptoms' will be written at both ends. The participant will be instructed to mark a point on the line appropriate to the severity of the symptom. Wrist pain values in the resting position will be recorded before and after the 6-week program.

  6 week

• Strength measurement

  Lafayette Dynamometer: Lafayette Manual Muscle Testing device will be used to evaluate muscle strength. While the measurements are being made, the device will be kept stationary and the resistance given by the participant will be measured in Newtons. Measurements will be made in the sitting position for wrist flexion/extension and forearm flexion, and total muscle strength will be recorded.

  6 week

• Fatigue assessment

  Fatigue Severity Scale: The fatigue level of the participants will be evaluated with the Fatigue Severity Scale. It is a survey with 9 questions and 8-point Likert form.A high score means a high level of fatigue.

  6 week

• Grip strength assessment

  Jamar Hand Grip Dynamometer will be used to evaluate hand grip and finger flexor muscle strength. The participant will sit upright during the assessment. Elbow and knee angle will be 90 degrees. A full force grip will be required with the wrist in the neural position. The measurement will be performed 3 times with an interval of 10 seconds. Increasing values will indicate higher strength. Measurement results will be recorded in kilograms and pounds.

  6 week

Study Arms (2)

Experimental

EXPERIMENTAL

These participants will receive electromyostimulation simultaneously with strengthening exercise.

Device: Electromyostimulation; Other: Strengthening exercises

Sham control

SHAM COMPARATOR

These participants will receive sham electromyostimulation (current turned off) simultaneously with strengthening exercise.

Other: Strengthening exercises

Interventions

Electromyostimulation DEVICE

Electromyostimulation (EMS), a low-frequency current, will be used for electrical stimulation of the wrist flexor muscle group. Stimulation frequency will be applied as 25 Hertz. Care will be taken to ensure that the current intensity does not cause pain in the patient. The size of the EMS electrodes is 2 cm2 and they will be placed in the form of 4 electrodes on the wrist flexor muscles (inner wrist area) with a distance of 1 cm between them. Each strengthening session will be 15 minutes for 6 weeks, 3 days a week, for a total of 18 sessions. EMS application will be carried out together with strengthening exercises. Laica MD6078 branded device belonging to the researchers will be used.

Experimental

Strengthening exercises OTHER

All participants will do resistance exercises for strengthening, 3 sessions per week for 6 weeks. Each movement will be performed in 3 sets and 12 repetitions according to the planned intensity. Wrist curl, reverse wrist curl movements (with 10kg dumbbells) and power web flex grip movements will be applied simultaneously with EMS application. The program will last 15 minutes in total.

Experimental; Sham control
