An online survey using social media investigating the use of kinesiology type tape and McConnell type tape with clinicians who treat cycling related knee pain
Journal Title: Journal of Science and Cycling - Year 2014, Vol 3, Issue 2
Abstract
Background: From high profile events such as the Tour De France and the Olympics, it is noticeable that kinesiology type taping (KTT) is used widely within elite cycling for treatment of knee pain. Taping is a clinical treatment for the over-use/overload pathology of patello-femoral pain (PFP) in elite and experienced cyclists, however it is unknown as to whether it effects any biomechanical change that can be useful in a clinical setting. PFP in cycling is often referred to as cyclists’ knee or anterior knee pain, and has been reported to occur in over 25% of all cyclists. (Callaghan, 2005: Journal of Bodywork and Movement Therapies, 9, 226-236). Some cyclists are pre-disposed to excessive knee movement during the pedal stroke (Bailey et al, 2003: Journal of Sports Sciences, 21 (2), 649–657), and consequently at different power levels and cadences this movement may affect biomechanical factors at the knee. An increased understanding of taping and the biomechanics of the knee during cycling could greatly improve the active prevention and treatment of overuse problems during cycling. Purpose: To determine and evaluate any biomechanical changes around the knee in elite and experienced cyclists both with and without knee pain, using established taping techniques at varying powers.Methods: 12 asymptomatic participants and 8 symptomatic participants conducted three separate tests at three powers (100w, 200w & 300w) on a static trainer using a Powertap™ rear wheel and their own bike (fig 1). The study was conducted under three randomised conditions a) no tape, b) placebo tape, c) Kinesiology type tape (fig 2). Kinematic data were collected using a 10-camera Qualysis motion analysis system (fig 3). Reflective markers were placed on the foot, shank, thigh and pelvis using the CAST technique (fig 4). Visual 3D software was used to export to SPSS (fig 5&6). Results: Measurements and statistical analysis were undertaken in the knee, hip and ankle/foot. Mixed methods and repeated-measures two-way ANOVA test were performed together with posthoc Pairwise comparison with Bonferroni adjustment to examine differences in three-dimensional movement under the different conditions/powers. Results were presented in kinematic pattern, range of motion (ROM) and statistical differences (fig 6,7,8) for comprehensive clinical application and relevance. Alongside this, a new approach was investigated to measure the knee ‘in relation to’ both the hip/pelvis and ankle/foot (fig 6). Results indicate statistical differences between conditions and powers (Fig 7) however at this stage their clinical significance has not yet been fully determined. The lower powers indicate instability and the higher powers indicate changes both distally and proximally to the knee. There appears to be a separation in the differences between cyclists tested with and without pain, however this does not necessarily indicate that KTT produces this in isolation. The differences vary across conditions and powers. Discussion: It is noticeable that the knee is not the only implicated joint in cycling related knee pain and taping. In fact all the recent evidence in this area indicate that distal and proximal to the knee are key factors (Powers et al, 2013: Journal Orthop Sports Physical Therapy. 42 (6), A1-54). In line with this evidence both the hip/pelvis and foot indicate changes that may be relevant to clinical application of taping with cyclists. It remains possible that there is a link between these movement patterns and cycling related knee pain however further work is required to fully determine this. The answer to the question does tape change what is happening at the knee is yes. Does it do different things with those with pain? Again, yes, to some degree. That said however, the clinical relevance requires a deeper analysis of the kinematic pattern data alongside the range of motion. The work undertaken to date in this project indicates the complexities of both human movement and the variables of a highly repetitive sport. The statistical change in the sagittal plane may indicate a muscular effect from taping however there were also changes by neutral taping which is interesting considering the specific nature of the KTT technique. Perhaps this specificity is not as critical as often indicated by manufacturers? Conclusion: Cycling related knee pain is a complex and under-researched area and we understand little of its treatment efficacy and effectiveness. Further work is required to investigate the relationship within the kinematics measured in this study. Distal and proximal effects are broadly in line with gait-based evidence. For clinical significance the statistics, kinematic patterns and ROM need to be considered as a whole. Specific application of tape technique may not be critical to achieve a measurable change.
