and athlete. Can J Appl Sport Sci 6:87-92, 1981

The most important criterion

in selecting a test is specificity

The low relationship between dynamic and

isometric tests indicates that muscular

measures are specific to the test modality

rather than general qualities

Isometric test

Not specific to the performance of most human movements that

require dynamic activation of musculature through a

movement range

That is

Muscle Injuries: Is there a

necessity of Imaging?

Ultrasound Imaging in Sports

Medicine

The growing emphasis on the health and fitness

over the years has resulted in increases in both the

number and kind of sport-related injuries

Medicine

Musculoskeletal Ultrasound (MSUS) and Magnetic

Resonance imaging (MRI) have been the mainstay

of sports-injury imaging armamentarium.

Medicine

Better• Less expensive

• More widely accessible

• Real time dynamic imaging

• High resolution

• Simultaneous comparison

• Sonopalpation

Medicine

• User dependency

• Incomplete evaluation of the whole anatomy

due to its inhability to visualize

structures/pathologies inside the bony tissues

Muscle Injuries: Is there a

necessity of Imaging?

Indeed all the Imaging Procedures are not fully

functional; it means that they don’t give response

about the capacity of the injuried muscle to

produce power during a sports effort

HAMSTRING INJURIES EARLY DIAGNOSIS

Hamstring strains are the most common injuries in athletes

• H/Q Ratio < 60% with isokinetic device

was considered able to detect hamstring

lesions

• Force developed during eccentric work at

extremely high speed cannot be compared

with the force during isokinetic motion

• Isokinetic test cannot predict hamstring

injuries

• Aim of the present research is to introduce a new procedure to determine the amount of functional recovery after knee joint surgery

• We propose to compare the biomechanicperformance in the leg extensor test synchronised with sEMG, the H/Q sEMG ratio in jump test and the response in the EMG activity to vibratory stimuli, in the operated and in the uninjured legs

KACLiR Test

END POINT

KACLiR TEST

Leg extension assessment for mechanical

power calculation

A diagnostic technique consisting on monitoring the muscles EMGrms activity during free load leg extension and jumps was applied for identify strength and imbalance deficit of the operated (OL) and non operated (NOL) legs

KACLiR TEST

Whole body vibration treatment procedure

Diagnostic technique consisting on monitoring the

muscles EMGrms activity during vibration

was applied for identify altered neural strategies of

motoneuron pool recruitment

was 100% higher

in the operated leg

than in the non

operated one

Fourth step: EMG/WBV

KACLiR Test

RESULTS

The high EMG activity noted in the operated leg might be caused by

the inappropriate function of proprioceptors

During surgery the proprioceptors were severed,

resulting in hyperactivity duringvibration treatment, mediated by

muscle spindle receptors and alpha motoneurons

(Johansonn H, Lorentzon R, Sjolander P, Sojka P, Neuro-Orthop 1990.)

Analyzing and recording sEMG behaviourof extensor muscles during vibratory

stimulation could allow the quantificationand assessment of knee impairment dueto the proprioceptors inability to function

properly after surgery

KACLiR Test

CONCLUSIONI/II

Combination of isoinertial dynamic testsand vibration stimulation both associated

to sEMG recordings may allow fordetection of impairment of neuromuscularfunctionality as well as monitoring

progress of the rehabilitation programs inKnee ACL reconstruction
