What is a common frequency for muscle re-education in NMES therapy?

The correct answer indicates that a common frequency for muscle re-education in Neuromuscular Electrical Stimulation (NMES) therapy typically falls within the range of 35-50 Hz. This frequency range is optimal for effectively stimulating muscle contractions that mimic natural movement patterns, assisting in muscle re-education after injury or surgery.

Using this frequency helps to achieve a balance between comfort and effective muscle contraction. When using NMES for muscle re-education, the goal is to engage motor units effectively while minimizing discomfort for the patient. Frequencies within the 35-50 Hz range produce a strong enough contraction to facilitate muscle strengthening and functional movement without causing excessive fatigue or pain, which can occur at either lower or significantly higher frequencies.

Considering other frequency ranges: those below 35 Hz may not provide sufficient intensity for effective muscle re-education, while frequencies above 50 Hz can lead to fatigue more quickly and may not be as comfortable for the patient.
