Effect of the protocol on 
The ROM increased in all groups which underwent ROM testing. The fact that none of the interventions was able of inducing ROM increments beyond the observed in the ROM testing control group is truly relevant. The absence of such control group in a number of previous studies (Kaur & Sharma, Some other substantial aspects can explain the differences between the two works. First, the presence of a ceiling effect for ROM amplitude in our sample of physiological participants might limit the effects of the techniques, while there was room to improve in the work by Castellote‐Caballero et al (Castellote‐Caballero et al.,
