Adductor Squeeze Test
The adductor squeeze test is used in the diagnosis of groin injuries and for the measurement of adductor muscles strength.
It is important to assess the strength of the adductor muscles, as adductor muscles weakness is an intrinsic risk factor of groin injuries and individuals with adductor muscles weakness are more likely to sustain groin injuires.
Thus, the adductor squeeze test can be used as a screening tool to detect adductors muscle weakness and decrease the risk of groin injuries.
The test is performed in 3 positions which are 0°, 45° and 90° of hip flexion, with the patient lying supine.
Several angles are used due to the multi-factorial role of hip adductor muscles.
The examiner places his fist between the patient’s knees and the patient is instructed to squeeze the examiner’s fist, contracting the adductor muscles maximally.
Also, the strength of the hip adductors can be measured objectively by repeating the same manoeuvre with a handheld dynamometer or sphygmomanometer placed between patient’s knees as he squeezes them in.
A study by Delahunt et al (2011) concluded that the optimal test position is 45° of hip flexion, as high pressure values and high level of adductor muscles activity were recorded at 45°.
It has been shown to be a useful diagnostic tool in identifying groin pain (Verrall 2007) and it is an reliable and accurate measurement of adductor muscle strength (Malliaras 2009).
