Critical Points EFFECTS OF INJURY ON PROPRIOCEPTION,
GAIT, AND DURATION OF INJURY
• A decrease in proprioception and kinesthesia occurs after anterior cruciate ligament (ACL) injury. Changes that occur within the joint affect normal recruitment and timing patterns of the surrounding musculature.
![Page 4: Ultimate knee Rehabilitation](https://reader033.vdocuments.site/reader033/viewer/2022042713/5471ade7b4af9f9d0a8b4c5d/html5/thumbnails/4.jpg)
Critical Points EFFECTS OF INJURY ON PROPRIOCEPTION,
GAIT, AND DURATION OF INJURY• After ACL rupture, patients
walk with greater hamstring activity, a flexed knee, and minimal to no quadriceps electro myographic activity.
• Altered proprioception of the knee joint may last 1 to 3 yr after injury.

Critical Points EFFECTS OF INJURY ON PROPRIOCEPTION,GAIT, AND DURATION OF INJURY
• There is a significant decrease in muscle activation timing and recruitment order in the lower extremity in response to anterior tibial translation in ACL-deficient knees compared with uninjured controls.

Critical Points LOWER EXTREMITY MUSCLE STRENGTH
RECOVERY AFTER SURGERY
• Abnormal gamma loop function in quadriceps muscles from lack of normal sensory function (loss native ACL mechanoreceptors) in the reconstructed ACL.
• Non-optimal activation of muscles during voluntary contraction in ACL-deficient knees.

Developing a NeuromuscularRehabilitation program
• 1. The focus on functional movement
• 2. The principle of skill/ability level rehabilitation
• 3. The code for motor adaptation
….that ought to participate in this particular movement & accompany the stabilization of the body.
![Page 9: Ultimate knee Rehabilitation](https://reader033.vdocuments.site/reader033/viewer/2022042713/5471ade7b4af9f9d0a8b4c5d/html5/thumbnails/9.jpg)
Neuromuscular exercises – do they exist?
• Peripheral plasticity – muscle, the acrobat of adaptation
• Neuromuscular rehabilitation is not just about exercising.
It is about providing cognitive sensory-motor challenges that will facilitate motor learning/adaptation.

A functional approachin KNEE Rehabilitation
• Functional movement is defined here as the
unique movement array of an individual.
• Functional rehabilitation of a person to recover their movement capacity by using
own movement repertoire (whenever possible)
![Page 11: Ultimate knee Rehabilitation](https://reader033.vdocuments.site/reader033/viewer/2022042713/5471ade7b4af9f9d0a8b4c5d/html5/thumbnails/11.jpg)
A functional approachin KNEE Rehabilitation
• However, rehabilitation is likely to be less effective if the remedial movement patterns or tasks are outside the individual’s experience
(extra-functional).

Rehabilitation levels: skill and
ability level KNEE Rehabilitation
• The center of attention in this form of movement recovery is on the overall skill of performing the particular movement, which is loosely referred to as skill rehabilitation

Change in proprioceptive acuity
Damage to proprioceptive apparatus peripherally combined with nociception will result in unrefined motor output.

Experiences that contain the five code elements are more like to promote
adaptive changes within theneuromuscular system resulting in
movement and behavioural changes.

The transition from cognitive to autonomous phase during motor learning.
Throughout the transition some elements
will remain cognitive and autonomous.

To treat or not to treat
• Can the motor changes lead to further injury or progressive damage?
• The primary aim of neuromuscular rehabilitation is to help individuals to recover their control movement. It is unknown if rehabilitation would confer protective function against progressive tissue damage in the future.

Complexity
• Complexity rules! Don’t become lost in the labyrinth of the neuromuscular system; look at the whole, not at minute details.
![Page 35: Ultimate knee Rehabilitation](https://reader033.vdocuments.site/reader033/viewer/2022042713/5471ade7b4af9f9d0a8b4c5d/html5/thumbnails/35.jpg)
Creativity• Neuromuscular rehabilitation is a creative process;
it is not protocol-based. Every patient is different and presents with new challenges. You will forever have to problem-solve on your feet.
![Page 36: Ultimate knee Rehabilitation](https://reader033.vdocuments.site/reader033/viewer/2022042713/5471ade7b4af9f9d0a8b4c5d/html5/thumbnails/36.jpg)
Clinical certainty is uncertainty
• The only clinical certainty is uncertainty – don’t fight it, learn to work with it. You will never know all the answers but you will be expected to provide expert care.

Finally Think movement not muscles.
• There is nothing like one brain to stimulate another.
• Make it fun, interesting and continuously challenging.

• The Facility• Influence of Technology• Recognizing the importance of progressing
rehabilitation objectively and preventing the detrimental effects of immobilization, but also protecting the integrity of healing tissue.

Take Home
• One is the restoration of neuromuscular control almost immediately after surgical procedures to the knee joint to prevent deafferentation of the joint.
• The progression of the patient must be increased gradually, and therefore, it is the responsibility of the therapist to find a balance between a detrimentally slow progression and advanced techniques prematurely that could have dangerous results.
