Does Foam Rolling Increase Pressure Pain Threshold Of Ipsilateral Lower Extremity Antagonist And Contralateral Muscles?
Scott W. Cheatham   Medicine & Science in Sports & Exercise. 49(5S):1066, May 2017.

Sports medicine professionals often prescribe foam rolling as an intervention to treat myofascial restrictions. Of particular interest, is the effect foam rolling has on the ipsilateral antagonist muscle and contralateral muscles. Recent research has observed ROM changes in these muscles after a foam rolling intervention. To date, no studies have examined how foam rolling effects the pressure pain threshold (PPT) levels of the ipsilateral antagonist and contralateral muscles. PURPOSE: To examine the acute effects of a foam rolling intervention on ipsilateral antagonist and contralateral muscle group PPT levels. METHODS: Twenty-one healthy participants (mean age 27.52± 8.9 years) (M=13, F=8) were recruited for this study and signed an IRB consent. Participants underwent pretest and immediate posttest PPT measures after a 2-minute video-guided foam roll intervention to the left quadriceps. PPTs were measured using a digital algometer to the ipsilateral left hamstrings and right quadriceps. Pretest and posttest measures were calculated using the paired t-test. Statistical significance was considered p< 0.05 using a two-tailed test. RESULTS: A significant difference was found between pretest to posttest measures for the ipsilateral hamstrings (t (20) = -6.2, p<0.001) and contralateral quadriceps (t (20) = -9.1, p<0.001) suggesting an increase in PPT.

CONCLUSIONS: These finding suggest that foam rolling of the quadriceps musculature may have an acute effect on the PPT of the ipsilateral hamstrings and contralateral quadriceps muscles. Individual may feel less discomfort due to a higher PPT. The ipsilateral decrease in hamstring PPT may have occurred through reciprocal inhibition and agonist pain perception from rolling on the left quadriceps. The cross-over effect of decreased right quadriceps PPT may have been from a more global neurophysiological response. Clinicians must consider these results to be exploratory and future investigations examining this intervention on PPT is warranted.
