Brief summary

To determine changes in thigh muscle function and knee pain after a partial meniscectomy surgery and to also determine the effects of applying electrical stimulation to the knee to determine if this improves thigh muscle function and decreases pain.

Detailed description

The objective for this study is to determine the differences in corticospinal excitability and central sensitization of nociceptive pathways in individuals with a history of arthroscopic partial meniscectomy compared to healthy controls. Our central hypothesis is that quadriceps weakness following partial meniscectomy is due to higher levels of corticospinal excitability and central sensitization of nociceptive pathways, which can be modified with therapeutic interventions.

Interventions

OTHERTranscutaneous Electrical Nerve Stimulation

The TENS electrodes will be applied on the medial and lateral superior, as well as the medial and lateral inferior, borders of the patella. A continuous biphasic pulsatile current (150 Hz, phase duration 150 µs) will be applied at an intensity that produces a comfortable sensation but not a muscle contraction. The duration of intervention will be 40 minutes.
