Outcome Measures

Primary Outcomes (2)

  • Baseline Hand Muscle Strength

    The hand muscle strength will be measured with a dynamometer and will be expressed in Newton

    Baseline at 0 min

  • Hand muscle strength after treatment 20 min

    The hand muscle strength will be measured with a dynamometer and will be expressed in Newton

    After treatment 20 min

Secondary Outcomes (1)

  • Change from baseline in Muscle strength

    baseline at 0 min, immediately after treatment at 20 min

Study Arms (2)

High-Frequency

EXPERIMENTAL

Transcutaneous application of high frequency electrical current over the arm for a 20 minutes session. The intensity of the current will increase until participants report a "strong but comfortable" sensation, just below motor threshold.

Device: High-Frequency Stimulation

Sham stimulation

SHAM COMPARATOR

Electrodes are placed over the arm for a 20 minutes in the same manner as experimental group but will be applied a sham electrical stimulation increasing the current intensity of an unconnected channel

Device: sham Stimulation

Interventions

high-Frequency electrical stimulation over superficial ulnar and median nerve through the electrotherapy device Myomed 932. (Enraf-Nonius, Delft, Netherlands)

High-Frequency

Sham transcutaneous electrical stimulation over superficial ulnar and median nerve through the electrotherapy device Myomed 932. (Enraf-Nonius, Delft, Netherlands)
