“…All participants were healthy individuals aged between 18 and 35 years who had engaged in physical activities for 2 hours or more per week during the previous 12 months before the beginning of the study with no discrepancy of 1 cm or greater in lower leg length [26] and normal arch of foot measured by using the plantar arch index (A/B) [27]. Participants had no history of surgery or injury involving the lower leg, ankle or foot in the last 12 and 6 months respectively [20] and no knee pain with activity [28]. Procedures: All participants were randomly tested in a walking activity under 3 conditions: 1) no tape, 2) McConnell taping, and 3) SERF strap.…”

Background: Changes in patellofemoral joint biomechanics have the potential to influence function of the lower extremity. McConnell taping has been proposed to reduce pain in individuals with patellofemoral pain syndrome (PFPS). It is also believed to improve vastus medialis oblique (VMO) muscle, patellofemoral alignment, and stride length. The stability through external rotation of the femur (SERF) strap has been developed to pull the femur externally to stabilise the patellofemoral joint, in order to reduce patellofemoral pain and improve lower limb kinematics. A lack of literature has examined effects of these two treatment methods on plantar pressures. Therefore, the aim of this study was to investigate the effects of McConnell taping and the SERF strap on rearfoot plantar loading patterns during walking in healthy adults.Materials and Methods: Twenty-three participants (12 males and 11 females, age: 26.52±6.4 years) were randomly tested under 3 conditions: 1) no tape, 2) McConnell taping, and 3) SERF strap. Each participant was instructed to walk on a 2 m pressure plate at their own natural pace. Three valid stance phases of the right foot were recorded for each condition. Maximum pressures of medial heel and lateral heel, contact area of medial heel and lateral heel, initial heel contact, foot axis angle, and centre of pressure were collected.Results: There were significant differences of maximum pressures of lateral heel (p = 0.011) with McConnell taping condition and the SERF strap condition demonstrating higher pressures than the no-tape condition (p = 0.042, p = 0.010 respectively). However, significant differences of other variables were not found. Conclusion

“…A larger sample size may have resulted in a significant difference in MH maximum pressures between the 3 conditions. Excessive rearfoot pronation is frequently associated with PFPS development [31] so individuals with PFPS present with larger contact areas at the medial rearfoot [14,28] …”

“…Evaluation of motor tasks that are more challenging in terms of mechanical and muscular demands, such as managing stairs, may further contribute to the understanding of compensatory mechanisms generated by subjects with PFP, which are not observed during walking (Aliberti et al, 2010). Because of this, the experimental design included a seven-step staircase, each step being 18 cm high and 28 cm deep, with a 2 m walkway in front of and behind the staircase.…”

“…The exclusion criteria for the PFPS group were patellar tendinitis, meniscus and knee ligament injuries, and patellar instability. Exclusion criteria for both groups were: history of knee ligament, tendon or cartilage injury; patellar luxation trauma; previous knee surgery; or lower limb discrepancy equals to or greater than 1 cm 22 . As the PFPS is common in physically active individuals, a questionnaire was administered to both groups concerning the frequency, duration, and number of years they had been involved in physical activity.…”

The aim of the present study was to investigate the association between the patellofemoral pain syndrome and the clinical static measurements: the rearfoot and the Q angles. The design was a cross-sectional, observational, case-control study. We evaluated 77 adults (both genders), 30 participants with patellofemoral pain syndrome, and 47 controls. We measured the rearfoot and Q angles by photogrammetry. Independent t-tests were used to compare outcome continuous measures between groups. Outcome continuous data were also transformed into categorical clinical classifications, in order to verify their statistical association with the dysfunction, and χ2 tests for multiple responses were used. There were no differences between groups for rearfoot angle [mean differences: 0.2º (95%CI -1.4-1.8)] and Q angle [mean differences: -0.3º (95%CI -3.0-2.4). No associations were found between increased rearfoot valgus [Odds Ratio: 1.29 (95%CI 0.51-3.25)], as well as increased Q angle [Odds Ratio: 0.77 (95%CI 0.31-1.93)] and the patellofemoral pain syndrome occurrence. Although widely used in clinical practice and theoretically thought, it cannot be affirmed that increased rearfoot valgus and increased Q angle, when statically measured in relaxed stance, are associated with patellofemoral pain syndrome (PFPS). These measures may have limited applicability in screening of the PFPS development.
