Background: Roller massage (RM) has become a common intervention among health and fitness professionals. Recently, manufacturers have merged the science of vibration therapy and RM with the development of vibration rollers. Of interest, is the therapeutic effects of such RM devices. Purpose: The purpose of this study was to compare the effects of a vibration roller and nonvibration roller intervention on prone knee-flexion passive range of motion (ROM) and pressure pain threshold (PPT) of the quadriceps musculature. Methods: Forty-five recreationally active adults were randomly allocated to one of 3 groups: vibration roller, nonvibration roller, and control. Each roller intervention lasted a total of 2 minutes. The control group did not roll. Dependent variables included prone knee-flexion ROM and PPT measures. Statistical analysis included parametric and nonparametric tests to measure changes among groups. Results: The vibration roller demonstrated the greatest increase in PPT (180 kPa, P < .001), followed by the nonvibration roller (112 kPa, P < .001) and control (61 kPa, P < .001). For knee flexion ROM, the vibration roller demonstrated the greatest increase in ROM (7°, P < .001), followed by the nonvibration roller (5°, P < .001) and control (2°, P < .001). Between groups, there was a significant difference in PPT between the vibration and nonvibration roller (P = .03) and vibration roller and control (P < .001). There was also a significant difference between the nonvibration roller and control (P < .001). For knee ROM, there was no significant difference between the vibration and nonvibration roller (P = .31). A significant difference was found between the vibration roller and control group (P < .001) and nonvibration roller and control group (P < .001). Conclusion: The results suggest that a vibration roller may increase an individual’s tolerance to pain greater than a nonvibration roller. This investigation should be considered a starting point for future research on this technology.

In the current case series, three male patients aged 19–21 years, all participating in basketball activities during their competitive season, were evaluated and classified with patella tendinopathy. A combination of positional release therapy (PRT) treatment with therapeutic exercises was used to decrease pain and improve function. Over the course of the treatment, each patient improved outcomes at discharge and sustained the improvements at follow-up. The purpose of this paper is to compare the results of this case series with a study of the effects of eccentric exercises on physically active patients diagnosed with patella tendinopathy and participating in jumping sports.

Focused Clinical Question: What are the immediate effects of instrumented-assisted soft tissue mobilization (IASTM) application on measures of lower extremity range of motion, muscular power, and strength in physically active adults not currently suffering from a musculoskeletal injury? Clinical Bottom Line: Grade 1 evidence supports immediate improvements in lower extremity range of motion in physically active adults after IASTM application. However, the evidence is lacking to support IASTM to improve muscular power and strength. Therefore, additional research is warranted to determine the acute effects of IASTM use on muscular power and strength in healthy, physically active adults.
