Kinesiology Tape

Clinical Scenario: Joint instability is a common condition that often stems from inadequate muscle activation and results in precarious movement patterns. When clinicians attempt to mechanically treat the unstable joint rather than attending to the underlying cause of the instability, patient outcomes may suffer. The use of kinesiology tape (KT) on an unstable joint has been proposed to aid in improving lower-extremity neuromuscular control. Clinical Question: Does KT improve factors of neuromuscular control in an athletic population when compared with no-tape or nonelastic taping techniques? Summary of Key Findings: The current literature was searched, and 5 randomized controlled studies were selected comparing the effects of KT with no-tape or nonelastic taping techniques on lower-extremity neuromuscular control in an athletic population. Primary findings suggest KT is not more effective than no-tape or nonelastic tape conditions at improving lower-extremity neuromuscular control in a healthy population. Clinical Bottom Line: The current evidence suggests that KT is ineffective for improving neuromuscular control at the ankle compared with nonelastic tape or no-tape conditions. KT was also found to be ineffective at improving hip and knee kinematics in healthy runners and cyclists. However, preliminary research has demonstrated improved neuromuscular control in a population displaying excessive knee valgus during a drop jump landing, after the application of KT. Clinicians should be cautious of these conflicting results and apply the best available evidence to their evaluation of the patient’s status. Strength of Recommendation: There is grade B evidence that the use of KT on an athletic population does not improve biomechanical measures of ankle stability. There is inconclusive, grade B evidence that KT improves neuromuscular control at the knee in symptomatic populations.

Clinical Question: Does ankle dorsiflexion promote irradiation of ipsilateral lower extremity musculature during a maximal isometric quadriceps contraction task in a healthy population? Clinical Bottom Line: There is preliminary evidence supporting the use of active ankle dorsiflexion during isometric quadriceps exercises to promote increased quadriceps activation and force production. As isometric quadriceps exercises are often included in initial stage rehabilitation, increasing muscle activation and force production may be beneficial.

Clinical Question:In a healthy adult population, which push-up position produces the greatest mean serratus anterior (SA) activation, expressed as a percentage of maximum voluntary isometric contraction (MVIC)?Clinical Bottom Line:In a healthy population, there is moderate evidence to support the use of the standard push-up on an unstable surface, elbow push-ups on stable and unstable surfaces, wall push-ups on an unstable surface, the full weight-bearing position using the Cuff Link system, and all three hand positions (shoulder width, wide base, and narrow base) with and without the use of the Perfect Pushup™ handgrips for the purpose of SA strengthening. These exercises produced a mean SA activation of at least 50% of the MVIC in the four cross-sectional studies that were reviewed for this critically appraised topic.

Context: Neuromuscular control deficit has been reported in people with chronic ankle instability (CAI) and hopping exercises have been recommended as a functional training tool to prevent lower limb injury, but its effects on lower-extremity neuromuscular control in those with CAI are unclear. Objective: To investigate the effect of hop stabilization training on neuromuscular control and self-reported function in college basketball players with CAI. Study Design: A randomized controlled trial. Setting: Research Laboratory. Patients (or Other Participants): A total of 28 college basketball players with CAI were randomly assigned to the experimental hop stabilization group (age = 22.78 [3.09] y, weight = 82.59 [9.51] kg, and height = 187.96 [7.93] cm) or the control group (age = 22.57 [2.76] y, weight = 78.35 [7.02] kg, and height = 185.69 [7.28] cm). Intervention: Participants in the experimental group performed supervised hop stabilization exercises 3 times per week for 6 weeks. The control group received no intervention. Main Outcome Measures: Preparatory and reactive muscle activation levels and muscle onset time were assessed from 8 lower-extremity muscles during a jump-landing task before and after the 6-week training program. Results: Significant improvements in preparatory muscle activation, reactive muscle activation, and muscle onset time were noted across the lower-extremity in the experimental group relative to the control group (P < .05). Self-reported function also improved in the experimental group relative to the control group (P < .05). Conclusions: These findings demonstrate that 6 weeks of hop stabilization training is effective in improving neuromuscular control and self-reported function in college basketball players with CAI. Hop stabilization exercises can be incorporated into the rehabilitation program for CAI.

Background: The purpose of the study was to determine the effect of kinesiology tape (KT) on lower limb muscle activation during computerized dynamic posturography (CDP) tasks and ankle kinesthesia in individuals with chronic ankle instability (CAI).Methods: Thirty-five men with CAI participated in this study. The experimental procedure followed a repeated measures design. Muscle activation of lower extremity and ankle kinesthesia of participants were measured using four taping treatments, namely, KT, athletic tape (AT), sham tape (ST), and no tape (NT) in a randomized order. Muscle activation was assessed using surface electromyography (sEMG) synchronized with CDP tests from seven lower extremity muscles of the unstable limb. Ankle kinesthesia was measured by using a threshold to detect the passive motion direction of the unstable ankle. Parameters were analyzed by using a one-way repeated measures ANOVA and followed by pairwise comparisons with a Bonferroni correction.Results: No significant difference was observed among different taping treatments for the majority of parameters during CDP. Except for condition 4 with open eyes, sway-referenced surface, and fixed surround in the sensory organization test (SOT), gastrocnemius medialis root mean square (RMS) was 28.19% lower in AT compared with NT (p = 0.021, 95% CI = 0.002–0.039), while gastrocnemius lateralis RMS was 20.25% lower in AT compared with KT (p = 0.038, 95% CI = 0.000–0.021). In forward-small sudden translation from motor control test (MCT), for peroneal longus (PL), RMS was 24.04% lower in KT compared with ST (p = 0.036, 95% CI = 0.000–0.018). In toes-down sudden rotation from adaption test (ADT), for PL, RMS was 23.41% lower in AT compared with ST (p = 0.015, 95% CI = 0.002–0.027). In addition, no significant difference was observed for a threshold to the detection of passive motion direction among different taping treatments.Conclusion: This study indicated that KT had minimal effect on the muscle activation of the unstable lower limb during static stance, self-initiated, and externally triggered perturbation tasks from CDP and ankle kinesthesia among individuals with CAI, suggesting that the benefit of KT was too small to be clinically worthwhile during application for CAI.

Clinical Scenario: Pain and range of motion (ROM) deficits are 2 issues that are commonly treated by clinicians. In certain instances, clinicians are tasked with treating patients who report with both pain and limited mobility. Currently, clinicians utilize a variety of different methods to combat pain and ROM limitations, but in singularity. However, contralateral exercises (CEs) may be a viable option that can have an effect on pain, ROM, or simultaneous effect on both. Clinical Question: For patients with pain and/or ROM deficits, will CE decrease pain and increase ROM? Summary of Findings: CE can have a significant effect on ipsilateral muscle activation, strength, as well as available motion on the contralateral limb. However, there is limited research on CE that explores effects on pain. Clinical Bottom Line: According to current evidence, CE can be a feasible option for clinicians trying to increase a patient’s ROM. Furthermore, there can be enhanced effects on stability, muscle strength, and muscle activation due to CE. Strength of Recommendation: Studies that have been included are a level of 4 or higher based on Center for Evidence Based Medicine. However, future studies both of higher levels and variability should be conducted.

Context:Limitations in gastrocnemius/soleus flexibility that restrict ankle dorsiflexion during dynamic tasks have been reported in individuals with patellofemoral pain (PFP) and are theorized to play a role in its development.Objective:To determine the effect of restricted ankle-dorsiflexion range of motion (ROM) on lower extremity kinematics and muscle activity (EMG) during a squat. The authors hypothesized that restricted ankle-dorsiflexion ROM would alter knee kinematics and lower extremity EMG during a squat.Design:Cross-sectional.Participants:30 healthy, recreationally active individuals without a history of lower extremity injury.Interventions:Each participant performed 7 trials of a double-leg squat under 2 conditions: a nowedge condition (NW) with the foot flat on the floor and a wedge condition (W) with a 12° forefoot angle to simulate reduced plantar-flexor flexibility.Main Outcome Measures:3-dimensional hip and knee kinematics, medial knee displacement (MKD), and ankle-dorsiflexion angle. EMG of vastus medialis oblique (VMO), vastus lateralis (VL), lateral gastrocnemius (LG), and soleus (SOL). One-way repeated-measures ANOVAs were performed to determine differences between the W and NW conditions.Results:Compared with the NW condition, the wedge produced decreased peak knee flexion (P < .001, effect size [ES] = 0.81) and knee-flexion excursion (P < .001, ES = 0.82) while producing increased peak ankle dorsiflexion (P = .006, ES = 0.31), ankle-dorsiflexion excursion (P < .001, ES = 0.31), peak knee-valgus angle (P = .02, ES = 0.21), and MKD (P < .001, ES = 2.92). During the W condition, VL (P = 0.002, ES = 0.33) and VMO (P = .049, ES = 0.20) activity decreased while soleus activity increased (P = .03, ES = 0.64) compared with the NW condition. No changes were seen in hip kinematics (P > .05).Conclusions:Altering ankle-dorsiflexion starting position during a double-leg squat resulted in increased knee valgus and MKD, as well as decreased quadriceps activation and increased soleus activation. These changes are similar to those seen in people with PFP.

Background: Occupational footwear and a prolonged duration of walking have been previously reported to play a role in maintaining postural stability. The purpose of this paper was to analyze the impact of three types of occupational footwear: the steel-toed work boot (ST), the tactical work boot (TB), and the low-top work shoe (LT) on previously unreported lower extremity muscle activity during postural stability tasks. Methods: Electromyography (EMG) muscle activity was measured from four lower extremity muscles (vastus medialis (VM), medial hamstrings (MH), tibialis anterior (TA), and medial gastrocnemius (MG) during maximal voluntary isometric contractions (MVIC) and during a sensory organization test (SOT) every 30 min over a 4 h simulated workload while wearing ST, TB, and LT footwear. The mean MVIC and the mean and percentage MVIC during each SOT condition from each muscle was analyzed individually using a repeated measures ANOVA at an alpha level of 0.05. Results: Significant differences (p < 0.05) were found for maximal exertions, but this was limited to only the time main effect. No significant differences existed for EMG measures during the SOT. Conclusion: The findings suggest that occupational footwear type does not influence lower extremity muscle activity during both MVIC and SOT. Significantly lower muscle activity during maximal exertions over the course of the 4 h workload was evident, which can be attributed to localized muscular fatigue, but this was not sufficient to impact muscle activity during postural stability tasks.

Context: Fatigue of the gluteus medius (GMed) muscle might be associated with decreases in postural control due to insufficient pelvic stabilization. Men and women might have different muscular recruitment patterns in response to GMed fatigue. Objective: To compare postural control and quality of movement between men and women after a fatiguing hip-abduction exercise. Design: Descriptive laboratory study. Setting: Controlled laboratory. Patients or Other Participants: Eighteen men (age = 22 ± 3.64 years, height = 183.37 ± 8.30 cm, mass = 87.02 ±12.53 kg) and 18 women (age = 22 ± 3.14, height = 167.65 ± 5.80 cm, mass = 66.64 ± 10.49 kg) with no history of low back or lower extremity injury participated in our study. Intervention(s): Participants followed a fatiguing protocol that involved a side-lying hip-abduction exercise performed until a 15% shift in electromyographic median frequency of the GMed was reached. Main Outcome Measure(s): Baseline and postfatigue measurements of single-leg static balance, dynamic balance, and quality of movement assessed with center-of-pressure measurements, the Star Excursion Balance Test, and lateral step-down test, respectively, were recorded for the dominant lower extremity (as identified by the participant). Results: We observed no differences in balance deficits between sexes (P &gt; .05); however, we found main effects for time with all of our postfatigue outcome measures (P ≤ .05). Conclusions: Our findings suggest that postural control and quality of movement were affected negatively after a GMed-fatiguing exercise. At similar levels of local muscle fatigue, men and women had similar measurements of postural control.

Clinical Scenario: Patients with chronic ankle instability (CAI) commonly display lower levels of self-reported function and health-related quality of life. Several rehabilitation interventions, including manual therapy, have been investigated to help CAI patients overcome these deficits. However, it is unclear if the addition of manual therapy to exercise-based rehabilitation is more effective than exercise-based rehabilitation alone. Clinical Question: Does incorporating manual therapy with exercise-based rehabilitation improve patient-reported outcomes when compared with exercise-based rehabilitation alone? Summary of Key Findings: The literature was searched for articles that examined the difference in outcomes for patients with CAI between manual therapy with exercise-based rehabilitation and exercise-based rehabilitation alone. A total of 3 peer-reviewed randomized controlled trials were identified. Two articles demonstrated improved patient-reported outcome scores following the incorporation of manual therapy with exercise-based rehabilitation, whereas one study found no statistically significant differences between interventions. Clinical Bottom Line: The current evidence suggests that incorporating manual therapy in addition to exercised-based rehabilitation may improve patient-reported outcome scores in patients with CAI. Strength of Recommendation: In accordance with the Strength of Recommendation Taxonomy, the grade of A is recommended due to consistent evidence from high-quality studies.
