Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Quadriceps atrophy is one of the most common post-operative side effects of anterior cruciate ligament (ACL) reconstruction, total knee arthroplasty, and many other surgeries including meniscal repairs, patella realignment procedures, and microfracture procedures. Due to the swelling within the joint after injury or surgery to the knee, the joint inflammation cascade occurs and leads to the quadriceps being arthrogenically inhibited by spinal neuron inhibition as a protective mechanism. These neural changes usually lead to decreased voluntary quadriceps contraction. Additional contributions of inhibition from post-operative pain, patient apprehension, and surgical procedure requiring protection of the repaired tissue. The sooner one regains control of the quadriceps muscles the less atrophy occurs, reductions in strength are minimized, and the more optimal the outcome is achieved for patient recovery.
Studies have shown that neuromuscular electrical stimulation (NMES), Transcutaneous electrical nerve stimulation (TENS), and biofeedback techniques can limit post-operative quadriceps atrophy and can return strength of the quadriceps back to normative values faster than without those techniques and traditional therapeutic exercise and have better long-term outcomes based on pain, functional outcomes, and return to sport participation rates.
Irradiation effect is a proprioceptive neuromuscular facilitation technique that causes an overflow of neuronal energy from distal to proximal muscles to increase muscle activity of a targeted muscle. This technique can be used to selectively recruit weaker motor units through the application of resistance or stimulation. By inducing a stronger contractile force of the quadriceps, our hope is to return quadriceps function to normal quicker with less atrophy and greater strength.
The investigators hypothesize that ankle positioning in maximal dorsiflexion (DF) changes the quantity of contraction as a percent of the reference voluntary contraction when performing a supine straight leg raise compared with having the foot in neutral (0°), relaxed, and plantarflexed (PF) positions. This may help provide insight into proper instruction and cuing for patients to return quadriceps neuromuscular control sooner and thus limiting quadriceps atrophy.

Straight Leg Raise exercise
Patient lying supine will lift leg to the height of the contralateral knee flexed to 90 degrees with the ankle positioned and tested in all three positions (dorsiflexion, neutral, and plantarflexion)
