active isolated stretching (ais)

The Active Isolated Stretching (AIS) method of muscle lengthening and fascial release is a type of Athletic Stretching Technique that provides effective, dynamic, facilitated stretching of major muscle groups, but more importantly, AIS provides functional and physiological restoration of superficial and deep fascial planes. Over the past few decades many experts have advocated that stretching should last up to 60 seconds. For years, this prolonged static stretching technique was the gold standard. However, prolonged static stretching actually decreases the blood flow within the tissue creating localized ischemia and lactic acid buildup. This can potentially cause irritation or injury of local muscular, tendinous, lymphatic, as well as neural tissues, similar to the effects and consequences of trauma and overuse syndromes.

The AIS Technique - Deep, Superficial Fascial Release

aisPerforming an Active Isolated Stretch of no longer than two seconds allows the target muscles to optimally lengthen without triggering the protective stretch reflex and subsequent reciprocal antagonistic muscle contraction as the isolated muscle achieves a state of relaxation. These stretches provide maximum benefit and can be accomplished without opposing tension or resulting trauma. Aaron Mattes' myofascial release technique, which also incorporates Active Isolated Stretching, uses active movement and reciprocal inhibition to achieve optimal flexibility. Using a 2.0 second stretch has proven to be the key in avoiding reflexive contraction of the antagonistic muscle. Without activating muscle group contraction, restoration of full range of motion and flexibility can be successfully achieved.





Hamstrings Lower - Strain/Tear

hamstring stretchLower hamstring problems may be caused by inadequate hamstring flexibility, weakness of the gluteus maximus and adductor magnus are important hip extensors, which if weak, allow increased load on the hamstrings. Hamstring weakness in which the short head and long head of the biceps femoris may not have optimum function together or from weakness during eccentric (lengthening) contraction of the hamstring muscles. The hamstring strain may be at the distal semitendinosus, semimembranosus, or double insertion biceps femoris.

Most people who suffer an acute hamstring strain will experience some of the following:

Sharp pain. When the injury occurs, one may feel an abrupt, sharp pain at the back of the thigh or buttocks.

A "pop" sound or sensation. This sudden pain is sometimes accompanied by an audible or palpable "pop" and a sensation of the leg giving way.

Difficulty moving and bearing weight. Following a hamstring injury, it may be hard or impossible to continue activity. The person may even have trouble walking with a normal gait, getting up from a seated position, or descending stairs.19,36,37 Acute hamstring injury patients can also have a "stiff legged" gait with noticeable limp.

Bruising. Sometimes bruising and discoloration can be seen along the back of the thigh.

Swelling and deformity. For cases in which there has been a complete tear of the muscle-tendon junction (myotendinous rupture), there may be bruising along with palpable defects, such as muscle lumpiness, under the skin. These defects can be felt and seen with contraction.

Pain and discomfort when sitting. In avulsion type and proximal hamstring injuries, where the tendon breaks away from the pelvic bone, patients will commonly have sitting pain and discomfort.

Shoulder Impingement

The typical symptoms of impingement syndrome include difficulty reaching up behind the back, pain with overhead use of the arm and weakness of shoulder muscles. If tendons are injured for a long period of time, the tendon can actually tear in two, resulting in a rotator cuff tear. There is usually consistent irritation in the subacromial region. Extrinsic causes such as an acromial spur, tendon calcification, a curved or hooked acromion, or acromioclavicular osteophytes may be present. Most frequently impingement involves the musculotendinous portion of the supraspinatus, the infraspinatus, the subscapularis, or the long head of the biceps.
