Effect of Kinesiology Tape on Measurements of Balance in Subjects With Chronic Ankle Instability: A Randomized Controlled Trial

Effects of Kinesio Taping on Neck Pain: A Meta-Analysis and Systematic Review of Randomized Controlled Trials

INTRODUCTION

Neck pain constitutes a prevalent and burdensome health issue, substantially impairing patients' quality of life and functional capabilities. Kinesio taping (KT), a commonly employed intervention within physical therapy, holds promise for mitigating such symptoms; however, a comprehensive evaluation of its efficacy and evidence base is lacking. Therefore, this study endeavors to systematically investigate the therapeutic effects of KT on both subjective neck pain intensity and objective measures of physical activity limitations through a rigorous meta-analytic approach. By synthesizing existing literature and scrutinizing methodological nuances, we aim to furnish healthcare practitioners with evidence-informed insights, facilitating more judicious clinical decision-making and optimizing patient outcomes.

METHODS

According to the PRISMA guidelines, we conducted searches on PubMed, Cochrane Library, Embase, and Web of Science for randomized controlled trials (RCTs) investigating the efficacy of KT in treating neck pain. Screening was performed based on predefined inclusion and exclusion criteria. Characteristics of the included RCTs were extracted. Trial heterogeneity was assessed using the I2 statistic. Meta-analysis was conducted using Stata 17 software. Risk of bias and methodological quality were evaluated using the Cochrane Risk of Bias 2 tool and the PEDro scale, respectively.

RESULTS

In our analysis of 10 RCTs involving 620 patients meeting our inclusion criteria, KT demonstrated significant beneficial effects on neck pain, notably surpassing conventional treatment (weighted mean difference = -0.897, 95% CI -1.30 to -0.49, P < 0.001). Subgroup analysis further revealed that KT exhibited particularly pronounced efficacy in the treatment of nonspecific neck pain and mechanical neck pain, with a more substantial effect observed after 4 weeks of KT intervention compared to 1 week. Moreover, KT demonstrated superior efficacy in alleviating pain symptoms compared to both conventional treatment and sham interventions.

CONCLUSION

KT has demonstrated efficacy in reducing neck pain and improving cervical dysfunction among patients. Prolonged KT treatment or its combination with other therapeutic modalities may potentially enhance therapeutic outcomes.

Effects of Kinesio taping on lower limb biomechanical characteristics during unexpected jumping in patients with chronic ankle instability

PURPOSE

The current biomechanical research on the application of Kinesio taping (KT) to patients with chronic ankle instability (CAI) has focused on testing the expected movements. However, unexpected movements are more common in actual sports. Therefore, the present study aimed to investigate the effects of KT on the biomechanical characteristics of the knee and ankle joints during unexpected jumping movements.

METHODS

Twenty-one patients with unilateral CAI were recruited to capture the biomechanical parameters during unexpected jumping movements under different interventions: no taping (NT), placebo taping (PT), and KT. A one-way repeated measures analysis of variance was used to compare the differences in knee and ankle biomechanical characteristics among patients with CAI between the three intervention conditions.

RESULTS

At initial contact, the KT group demonstrated a significant decrease in ankle plantarflexion and knee flexion angles compared to the NT group (p < 0.05). At the early landing phase, the KT group had a significant increase in peak ankle dorsiflexion angle, peak ankle eversion angle, peak ankle dorsiflexion moment, and peak ankle eversion moment compared to the NT and PT groups (p < 0.05). Furthermore, the KT group had a significantly reduced peak knee flexion angle, peak knee eversion angle, and peak vertical ground reaction force (p < 0.05) compared to the NT and PT groups.

CONCLUSION

KT significantly improves the sprain-prone touchdown posture of patients with CAI. And reducing the risk of ankle sprains during the early landing phase by promoting ankle dorsiflexion and eversion angles and moments.

Effects of Ankle Orthoses, Taping, and Insoles on Postural Stability of Individuals with Chronic Ankle Instability: A Systematic Review

Chronic ankle instability (CAI) is a prevalent condition characterized by recurring instances of the ankle giving way and persistent symptoms, including pain and diminished function. Foot and ankle external supports are commonly used in clinical practice and research for treating CAI. This systematic review aimed to assess the effects of foot and ankle external supports on the postural stability of individuals with CAI to guide clinical practice and inform future research. A comprehensive search was conducted in PubMed, Web of Science, Scopus, and Google Scholar databases from 1 January 2012 to 1 November 2022. Eighteen studies involving individuals with CAI were chosen in this systematic review. The quality of the included studies and risk of bias were assessed using Cochrane Collaboration's tool for randomized controlled trials, the Newcastle-Ottawa Scale for case-control studies, and the DELPHl-list for crossover trial studies. The external supports included in this review were ankle orthoses (elastic, semi-rigid, and active orthoses), taping (kinesiotaping and fibular reposition taping), and insoles (textured and supportive insoles). The outcome measures included static and dynamic postural stability tests, such as the single-leg stance test, star excursion balance test, Y-balance test, single-leg landing test, lateral jump test, walking test, and running test. The results showed that elastic orthoses, Kinesiotaping, and textured insoles demonstrated potential benefits in improving postural stability in individuals with CAI. Elastic orthoses decreased ankle joint motion variability, kinesiotaping facilitated cutaneous receptors and proprioceptive feedback, while textured insoles increased tactile stimulation and foot position awareness. However, the effects of semi-rigid orthoses, fibular reposition taping, and arch support insoles were inconsistent across studies. Future research should explore the long-term effects of these external supports, analyze the effects of different characteristics and combinations of supports, and employ standardized outcome measures and testing protocols for assessing postural stability.

Acute effects of kinesiology tape on dynamic balance control in chronic ankle instability: An exploratory study

OBJECTIVE

To investigate the acute effect of the four-strip kinesiology taping (KT) technique on dynamic balance control in the Y Balance Test (YBT), and to explore the relationship between the YBT and Cumberland Ankle Instability Tool (CAIT) scores in individuals with and without chronic ankle instability (CAI).

METHODS

16 CAI and 16 non-CAI participants were involved. Two groups completed the YBT in the no-tape barefoot and the KT condition at random. The CAIT was completed on the first day. Bonferroni test was used to analyze YBT scores in three directions for post hoc analysis. Spearman's correlation was used to analyze the relationship between YBT scores in the no-tape barefoot condition and CAIT scores.

RESULTS

This KT application significantly improved YBT performance. The YBT scores in the anterior direction (YBT-A), posteromedial direction (YBT-PM), and posterolateral direction (YBT-PL) for the CAI group were significantly improved after taping. However, in the non-CAI group, only YBT-PM score was significantly improved after taping. Three YBT scores were all moderately correlated with the CAIT score.

CONCLUSION

This KT technique can immediately improve dynamic balance in CAI patients. Dynamic balance performance was moderately related to the degree of self-perceived instability in individuals with and without CAI.

Effects of eight week core stability training on stable- and unstable-surface on ankle muscular strength, proprioception, and dorsiflexion in athletes with chronic ankle instability

BACKGROUND

Chronic ankle instability (CAI) is a common injury among athletes. Research has reported reduced dorsiflexion range of motion, impairment of proprioception, and decreased muscle strength of the ankle in people with CAI. The aim of this research was to examine the effects of 8-week core stability training on stable and unstable surfaces on ankle muscular strength, proprioception, and dorsiflexion range of motion (ROM) in athletes with CAI.

METHODS

Thirty-six athletes with CAI (age 22.42 ± 2.76 years; height 169.11 ± 3.52 cm; weight 68.46 ± 2.75 kg) participated in this study. They were divided into three groups: unstable-surface group (UG) (n = 12), stable-surface group (SG) (n = 12), and control group (CG) (n = 12). The UG and SG performed the core stability exercise protocol for 8 weeks, 3 sessions per week. The CG received their usual care and daily activities. Outcomes were measured pre-sessions and post-sessions.

RESULTS

The peak torque showed significant increases in the UG and SG compared with the CG during plantar flexion, dorsiflexion, inversion, and eversion (P < 0.05). There were also significant increases in UG compared with SG (P < 0.05). The proprioception showed significant decreases in UG compared with SG and CG (P < 0.05). The dorsiflexion ROM showed significant increases in UG and SG compared with CG. There were also significant increases in UG compared with SG (P < 0.05).

CONCLUSIONS

It seems that core stability exercises on trampoline surface helps improve the measured parameters in athletes with ankle instability. Therefore, this type of training is recommended as a therapeutic option for Individuals with CAI.

Evaluating the effects of two different kinesiology taping techniques on shoulder pain and function in patients with hypermobile Ehlers-Danlos syndrome

Background

Ehlers-Danlos Syndrome (EDS) is a group of inherited connective tissue disorders which predominantly affects women and has a prevalence as high as 1 in 5,000 individuals. Hypermobile EDS (hEDS) is the most common subtype of EDS and is characterized by multi-joint pain, particularly in large joints such as the shoulder. Physical therapy is often utilized to address the pain, physical impairments, and functional loss in patients with EDS. Kinesiology Tape (KT) is an intervention commonly used by physical therapists for treating shoulder pain and dysfunction. Studies related to the effectiveness of KT in patients with shoulder pain is equivocal and there are a lack of studies specifically studying the effects of KT in an EDS population.

Purpose

The purpose of this study was to assess the efficacy and short-term effects of two different KT techniques on shoulder pain and function in individuals with hEDS and shoulder pain.

Methods

Participants were recruited from EDS support groups in the New England area of the United States; were diagnosed with hEDS by their physician; and had shoulder pain. Baseline demographic information was obtained for each participant followed by completion of 4 patient reported outcome (PRO) measures: the Upper Extremity Functional Index, QuickDASH (Disabilities of the Arm, Shoulder, & Hand), Shoulder Pain and Disability Index, and the Western Ontario Shoulder Instability Index. Current pain level, average pain over the past 24 h, and worst pain over the past 24 h were recorded using the numeric pain rating scale (NPRS). Subjects were randomly assigned to receive either an experimental shoulder KT procedure or a control shoulder taping. Immediately after taping, the NPRS was reassessed. Subjects then returned 48 h later to repeat the NPRS and PRO measures.

Results

There was no significant difference between the experimental and control tape groups for any outcome measure. There was a significant improvement from pre-taping to 48-hours post taping for each of the 4 PRO measures with large effect sizes (p < 0.001; ƞ _p ² = .517-.719). Likewise, average, and worst pain over the last 24 h significantly improved with large effect sizes over the same period (p = 0.005; ƞ _p ² = .225 and p < 0.001; ƞ _p ² = .382, respectively). Current NPRS levels significantly improved from pre-tape to immediately post-tape (p = .023, ƞ _p ² = .131) and was maintained through the 48-hour follow up, although no further improvement was seen.

Conclusion

KT is an inexpensive and relatively safe intervention that is easy to apply and can offer temporary improvements in pain and function for patients with EDS and shoulder pain.

Effects of Conservative Interventions on Static and Dynamic Balance in Individuals With Chronic Ankle Instability: A Systematic Review and Meta-analysis

OBJECTIVE

To determine which conservative interventions are effective for static and dynamic balance in patients with chronic ankle instability (CAI).

DATA SOURCES

PubMed, Cochrane Library, Web of Sciences, and CINAHL databases were searched up to March 20, 2022.

STUDY SELECTION

Randomized controlled trials investigating the effects of conservative interventions on static and/or dynamic balance in patients with CAI compared with those of different conservative interventions or controls were included.

DATA EXTRACTION

Two independent reviewers extracted the data. Certainty of the evidence was assessed using the GRADE approach.

DATA SYNTHESIS

Forty-eight studies (1906 participants) were included. Whole-body vibration training (WBVT) was significantly more effective than controls for both static (standardized mean difference, 1.13; 95% confidence interval [CI], 0.58-1.68; moderate-certainty evidence) and dynamic balance (0.56; CI, 0.24-0.88; low-certainty evidence). Balance training (BT) and joint mobilization were significantly more effective than controls for dynamic balance (0.77; CI, 0.41-1.14; and 0.75; CI, 0.35-1.14, respectively), but not for static balance (very low to low-certainty evidence). Adding other interventions to BT had no significant effect on either type of balance compared with that of BT alone (moderate to low-certainty evidence). Strength training (ST) and taping had no significant effect on either type of balance (very low- to low-certainty evidence). Multimodal interventions were significantly effective in improving dynamic balance (0.76; CI, 0.32-1.20; low-certainty evidence). Adding transcranial direct current stimulation to ST was significantly more effective for dynamic balance than ST (0.81; CI, 0.08-1.53; moderate-certainty evidence). The effects on balance were not significantly different among BT, ST, and WBVT (very low- to low-certainty evidence).

CONCLUSIONS

The significantly effective interventions reviewed may be treatment options for balance impairments associated with CAI. However, interventions should be chosen carefully, as much of the certainty of evidence is very low to low.

Acute effect of kinesio tape on postural control in individuals with functional ankle instability following ankle muscle fatigue

Background: Kinesio taping (KT) is one of the therapeutic interventions in sports medicine practice. The study aims to assess the acute effect of different KT methods on postural control in individuals with functional ankle instability (FAI) after ankle muscle fatigue.

Methods: Twenty-eight participants with FAI were recruited to complete maximum voluntary isometric contraction (MVIC) and proprioception of ankle using isokinetic dynamometer, dynamic postural control using Y-balance test and static postural control using a force platform after a fatigue protocol in four taping conditions: facilitatory KT (FKT), ankle balance taping (ABT), sham taping (ST) and no taping (NT).

Results: No significant difference was observed for the data MVIC and proprioception after ankle muscle fatigue amongst the four taping treatments. A significant difference in Y-Balance Test was observed amongst the four taping treatments at posterolateral direction (p < 0.001) and posteromedial direction (p < 0.001), suggesting that KT may significantly improve dynamic postural control following ankle muscle fatigue. For Center of pressure (COP) measurements, the mediolateral COP sway range of NT was significantly larger than that of FKT (p = 0.003) and ST (p < 0.001), suggesting that the placebo effect of KT was inevitable.

Conclusion: The effect of KT seems increased dynamic postural control in individuals with FAI after ankle muscle fatigue, and this effect is not strongly related to the taping methods. By preventing fatigue-related impairments of postural control, KT may help reduce the risk of injury in individuals with FAI.

Nonanatomic All-Inside Arthroscopic Anterior Talofibular Ligament Repair With a High-Position Anchor versus Anatomic Repair: An Analysis Based on 3D CT

BACKGROUND

In patients with chronic ankle instability, it is important to repair the anterior talofibular ligament (ATFL) at the anatomic origin site. However, there are limited reports on the clinical outcomes according to anatomic ATFL repair.

PURPOSE

To compare the clinical outcomes after arthroscopic ATFL repair according to whether the anchor is fixed at an anatomic position.

STUDY DESIGN

Cohort study; Level of evidence, 3.

METHODS

We performed a retrospective review of consecutive patients who underwent arthroscopic ATFL repair for chronic ankle instability and were available for a minimum 2-year follow-up. The patients were divided into 3 groups according to the anchor position at the distal fibula on 3-dimensional computed tomography: anatomic arthroscopic ATFL repair (anatomic group), subanatomic arthroscopic ATFL repair (subanatomic group), and nonanatomic arthroscopic ATFL repair (nonanatomic group). The visual analog scale for pain, Foot and Ankle Outcome Score (FAOS), and Karlsson ankle functional score were measured as subjective outcomes. Posturographic analysis and radiologic evaluation using stress radiographs and axial view magnetic resonance imaging were performed as objective outcomes.

RESULTS

Of 96 patients, 16 were excluded per the exclusion criteria, and 80 were evaluated (anatomic group, n = 24; subanatomic group, n = 42; nonanatomic group, n = 14). The mean age of the patients was 34.5 years, and the mean follow-up period was 27.4 months. A between-group comparison revealed significant differences in FAOS, Karlsson score, and fall risk evaluated by posturography at the final follow-up. Post hoc analysis revealed that the anatomic group had better clinical scores on the FAOS than did the nonanatomic group in all 5 domains (all P < .017). Patients in the anatomic and subanatomic groups had better Karlsson scores and fall risk than those in the nonanatomic group (P = .004 and P = .013, respectively). In terms of objective outcomes, patients in the anatomic and subanatomic groups had better outcomes in fall risk than did those in the nonanatomic group (both P = .001). There were no differences in clinical scores and objective outcomes between the anatomic and subanatomic groups.

CONCLUSION

Nonanatomic ATFL repair showed inferior outcomes when compared with anatomic ATFL repair. When arthroscopic ATFL repair is performed, the anchor should be fixed in the anatomic position to improve prognosis.

Is Kinesio Taping Effective for Sport Performance and Ankle Function of Athletes with Chronic Ankle Instability (CAI)? A Systematic Review and Meta-Analysis

Background and Objectives: Ankle injuries are the most common type of injury in healthy active individuals. If not treated properly, recurrent sprains can lead to a condition of chronic ankle instability (CAI). The aim of the present review is to evaluate the effects of Kinesio Taping (or KT) on sports performances and ankle functions in athletes with CAI. Materials and Methods: This systematic review with meta-analysis was carried out following the criteria of the Prisma Statement system (registered on Open Science Framework, number: 10.17605/OSF.IO/D8QN5). For the selection of the studies, PubMed, Scopus and Web of Science were used as databases in which the following string was used: (“kinesiology tape” OR “tape” OR “taping” OR “elastic taping” OR “kinesio taping” OR “neuro taping”) AND (unstable OR instability) AND (ankle OR (ankle OR “ankle sprain” OR “injured ankle” OR “ankle injury”)). The Downs and Black Scale was used for the quality analysis. The outcomes considered were gait functions, ROM, muscle activation, postural sway, dynamic balance, lateral landing from a monopodalic drop and agility. Effect sizes (ESs) were synthesised as standardized mean differences between the control and intervention groups. Calculation of the 95% confidence interval (CI) for each ES was conducted according to Hedges and Olkin. Results: In total, 1448 articles were identified and 8 studies were included, with a total of 270 athletes. The application of the tape had a significant effect size on gait functions, ROM, muscle activation and postural sway. Conclusions: The meta-analysis showed a significant improvement in gait functions (step velocity, step and stride length and reduction in the base of support in dynamics), reduction in the joint ROM in inversion and eversion, decrease in the muscle activation of the long peroneus and decrease in the postural sway in movement in the mid-lateral direction. It is possible to conclude that KT provides a moderate stabilising effect on the ankles of the athletes of most popular contact sports with CAI.

Kinesio taping as an alternative treatment for manual laborers with carpal tunnel syndrome: A double-blind randomized clinical trial

BACKGROUND

Carpal tunnel syndrome (CTS) is one of the most common forms of peripheral neuropathies due to median nerve compression. Occupational factors, such as repetitive hand motions are believed to be associated with this condition.

OBJECTIVE

This clinical trial assessed the effect of Kinesio taping (KT) of hand flexor muscles on the management of mild to moderate CTS in Iranian manual laborers.

METHODS

Thirty manual laborers with mild to moderate CTS participated in this clinical trial. They were assigned to an intervention or a control group. The treatment consisted of a 2-week KT followed by a 4-week follow-up. The control group received sham KT without tension applied. Boston Carpal Tunnel Questionnaire scores, pinch and grip force tests, and electrophysiological examination of the median nerve were performed for each participant at baseline, 24 to 48 hours, and two to four weeks of follow-up. The statistical analysis of variance was performed (2 groups × 5 times) for all participants, comparing differences in the data within and between the two groups.

RESULTS

The baseline assessment revealed no inter-group differences in the clinical outcomes (P> 0.05). Comparisons of the changes in the electro-physiological and functional variables indicated significantly greater improvement in the KT group than in the sham counterpart (P< 0.05). No statically significant improvement was evident by the electrodiagnostic criteria in the sham-KT group (P> 0.05).

CONCLUSIONS

KT is an effective, safe, reliable, and conservative therapeutic choice for the management of patients with CTS. The treatment does not restrict the daily activities of patients nor has it any side effects.

Effect of Kinesiology Tape on Muscle Activation of Lower Extremity and Ankle Kinesthesia in Individuals With Unilateral Chronic Ankle Instability

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.

[Short-term effect of neuromuscular bandaging on balance and gait in Parkinson's disease: Pilot study]

INTRODUCTION

Parkinson's disease is a progressive and irreversible neurodegenerative process characterized by tremor at rest, bradykinesia, stiffness, disorders in postural control, balance and gait. Kinesiology tape has a somatosensory stimulating effect, with benefits in postural control.

METHOD

A pilot study with a Physiotherapy Intervention Group and an Experimental Group (kinesiology tape was added) in gastrocnemius and lumbar spinal erectors. Outcome assessments were Berg scale, Tinetti scale (walking subscale), 10m test, TUG test, PDQ-39 and gastrocnemius electromyographic record. Three measurements were made: T0 (baseline), T1 (two days post-intervention) and T2 (one week post-intervention); PDQ-39 was administered at T0 and one month after the intervention.

RESULTS

Thirteen participants (stage III Hoehn and Yahr) were selected after applying the inclusion criteria (nine women and four men). N=7 Experimental Group and N=6 Physiotherapy Group. The intra-group contrast showed significant improvements in favor of the Experimental Group in Berg scale (T1 and T2), 10m test (T2) and in lower mean gastrocnemius muscle activity (T1). The inter-group contrast only evidenced differences in electromyographic recording of the muscle contraction of the right lower limb, after the application of kinesiology tape, in T1.

CONCLUSIONS

The application of kinesiology tape in the lumbar spinal erectors and gastrocnemius bilaterally could improve gait and balance, in subjects with Parkinson's disease in Hoehn and Yahr stage III, but its effect is not superior to conventional physiotherapy treatment.

Additional Inferior Extensor Retinaculum Augmentation After All-Inside Arthroscopic Anterior Talofibular Ligament Repair for Chronic Ankle Instability Is Not Necessary

BACKGROUND

Although several arthroscopic surgical techniques for the treatment of chronic ankle instability (CAI) have been introduced recently, the effect of inferior extensor retinaculum (IER) augmentation remains unclear.

PURPOSE

To compare the clinical outcomes after arthroscopic anterior talofibular ligament (ATFL) repair according to whether additional IER augmentation was performed or not.

STUDY DESIGN

Cohort study; Level of evidence, 3.

METHODS

We performed a retrospective review of consecutive patients who underwent arthroscopic ATFL repair surgery for CAI between 2016 and 2018. The mean age of the patients was 35.2 years (range, 19-51 years), and the mean follow-up period was 32.6 months (range, 24-48 months). Patients were divided into 2 groups according to the surgical technique used for CAI: arthroscopic ATFL repair (group A; n = 37) and arthroscopic ATFL repair with additional IER augmentation (group R; n = 45). The pain visual analog scale, American Orthopaedic Foot & Ankle Society score, Foot and Ankle Outcome Score, and the Karlsson Ankle Function Score were measured as subjective outcomes, and posturographic analysis was performed using a Tetrax device as an objective outcome. Radiologic outcome evaluations were performed preoperatively and at 2 years postoperatively using stress radiographs and axial view magnetic resonance imaging (MRI).

RESULTS

Out of 101 patients, 19 (18.5%) were excluded per the exclusion criteria, and 82 were evaluated. We identified 6 retears (7.3%) based on postoperative MRI evaluation. All patients who had ATFL retear on MRI (8.1% [3/37] in group A and 6.7% [3/45] in group R) demonstrated recurrent CAI with functional discomfort and anterior displacement >3 mm as compared with the intact contralateral ankle. All clinical scores and posturography results were improved after surgery in both groups (P < .001). However, there were no significant differences in the clinical results and radiologic findings between the groups.

CONCLUSION

The clinical and radiologic outcomes of patients with CAI improved after all-inside arthroscopic ATFL repair. However, additional IER augmentation after arthroscopic ATFL repair did not guarantee better clinical outcomes.

The effects of Kinesiology Tape on static postural control in individuals with functional ankle instability

OBJECTIVE

To investigate if applying Kinesiology Tape (KT) on the unstable ankle may improve static postural control in individuals with Functional ankle instability.

DESIGN

A repeated measured study. Participants performed a series of static quiet bipedal and unipedal stances on a force platform. Measurements were taken at three different times: baseline or no tape, immediately and 24 h after the taping application with the tape remaining on the ankle.

SETTING

A university's psychomotor laboratory.

PARTICIPANTS

Twenty young adults with Functional ankle instability aged from 18 to 30 years old.

OUTCOME MEASURES

Postural control was assessed by four measures derived from the centre of pressure data: Area of 95% Confidence ellipse, standard deviation of displacements, mean velocity and mean power frequency. The analysis of variance (ANOVA) was performed to determine any significant improvement in postural control over time due to KT.

RESULTS

Only minor changes in mean velocity and MPF in unipedal stances were observed immediately after KT application. However, the overall results indicated statistically insignificant improvements in postural control neither immediately after KT application nor after 24 h.

CONCLUSION

Results suggest that the use of KT did not affect bipedal and unipedal stances of individuals with functional ankle instability.

Ankle muscle activation during the limits of stability test in subjects with chronic ankle instability

OBJECTIVE

To study postural control and muscle activity during the limit of stability test (LOS) in subjects with chronic ankle instability.

DESIGN

Observational study.

SETTING

University laboratory.

PARTICIPANTS

10 healthy subjects were included in the control group and 10 subjects in the CAI group (age between 18 and 30 years, with history of the multiple ankle "giving way" episodes in the last six months and score ≤24 in the Cumberland Ankle Instability Tool).

MAIN OUTCOME MEASURES

A computerized dynamic posturography equipment was used for assessing the LOS. The electromyography activity of tibialis anterior (TA), soleus (SOL), medial gastrocnemius (MG) and peroneus longus (PL) was registered.

RESULTS

Subjects with CAI had a greater activation in TA to forward (p < .01), forward affected (p = .001), backward affected (p = .007) and backward directions (p < .01); in PL to forward affected (p < .01) and affected directions (p = .001); in MG to forward (p = .023) and affected directions (p < .01) and in SOL to the affected direction (p = .009). We observed restricted excursions and less directional control in subjects with CAI.

CONCLUSIONS

Subjects with CAI exhibited poorer ability to move their center of gravity within stability limits. In addition, they have an altered ankle muscle activity during LOS test toward the affected ankle joint.

Kinesio taping does not improve ankle functional or performance in people with or without ankle injuries: Systematic review and meta-analysis

OBJECTIVE

To investigate whether Kinesio taping technique, applied to ankles of healthy people as a preventive intervention and people with ankle injuries, is superior to sham or alternative interventions on ankle function.

DATA SOURCES

Medline, Embase, Amed, CINAHL, SPORTDiscus, Cochrane Library and Web of Science, from inception to August 2020.

REVIEW METHODS

The terms "ankle" and "kinesio taping" were used in the search strategy. Included studies were randomized controlled trials (including crossover design) investigating Kinesio taping effects on ankle functional performance compared to any alternative or control/sham technique.

RESULTS

From 5,572 studies, 84 met the eligibility criteria which evaluated 2,684 people. Fifty-eight meta-analyses from 44 studies were performed (participants in meta-analyses ranging from 27 to 179). Fifty-one meta-analyses reported ineffectiveness of Kinesio taping: moderate evidence for star excursion balance test (anterior direction), jump distance, dorsiflexion range of motion, and plantar flexion torque for healthy people (effect size = 0.08-0.13); low to very-low evidence for balance, jump performance, range of motion, proprioception, muscle capacity and EMG for healthy people; balance for older people; and balance and jump performance for people with chronic instability. Seven meta-analyses reported results favoring Kinesio taping (effect size[95% CI]): low to very-low evidence for balance (stabilometry, ranging from 0.42[0.07-0.77] to 0.65[0.29-1.02]) and ankle inversion (0.84[0.28-1.40]) for healthy people; balance for older people (COP velocity, 0.90[0.01-1.78]); and balance for people with chronic instability (errors, 0.55[0.06-1.04]).

CONCLUSIONS

Current evidence does not support or encourage the use of Kinesio taping applied to the ankle for improvements in functional performance, regardless the population.

Short-term and long-term effects of ankle joint taping and bandaging on balance, proprioception and vertical jump among volleyball players with chronic ankle instability

OBJECTIVE

This study hypothesized that the prolonged use of taping during athletic activities produces more significant increases in proprioception, balance, and vertical jump among volleyball players with CAI.

DESIGN

A randomized controlled study.

PARTICIPANTS

One-hundred participants with chronic ankle instability (CAI) participated in this study. Participants were distributed into 3-groups: taping group, bandaging group, and control group.

PRIMARY OUTCOME MEASURES

Proprioception (ankle range of motion absolute error), balance(Y-balance test), and vertical jump (vertical jump tester).

INTERVENTIONS

Three interventions were performed: ankle rigid taping, ankle bandaging, and placebo taping. The measurements were performed at baseline, immediately, 2-weeks and 2-months after support.

RESULTS

Immediately after supports, there were non-significant differences between all groups for proprioception, balance (P < .05). There was a significant difference between banding and control groups, and taping and control groups for the vertical jump (P < .05). After 2-weeks and 2-months, there were significant differences between bandaging and control groups, and taping and control groups for proprioception, balance, and vertical jump (P < .05). There were non-significant differences between taping and bandaging groups (P < .05) during all assessments.

CONCLUSION

This study indicated that ankle taping and bandaging immediately improve vertical jump only; while they improve proprioception, balance, and vertical jump after 2-weeks and 2-months.

Assessments of Sensorimotor Deficits Used in Randomized Clinical Trials With Individuals With Ankle Sprains and Chronic Ankle Instability: A Scoping Review

The main purpose of this scoping review was to summarize the most common tasks and outcome measures in randomized control trials (RCTs) used to assess sensorimotor function following ankle sprain and chronic ankle instability (CAI). We also aimed to summarize the description of inclusion criteria used in articles. We searched for RCTs published between 2008 and 2018 using the following databases: MEDLINE, PubMed, SPORTDiscus, and Web of Science. Eligible studies included participants of either sex who had had at least one ankle sprain with/without subsequent CAI. All articles assessed sensorimotor function. The tasks, outcome measures, and inclusion criteria were categorized, and frequencies of use in each category were calculated. Of 272 publications, 31 met the eligibility criteria. The most common task was single-limb stance (58% of 31). The most common outcome measure was the posterior-medial reach distance of the Star Excursion Balance Test (SEBT) (13 of 16 articles, 81%). Different inclusion criteria for a history of ankle sprains or CAI were used. A wide range of sensorimotor assessments and inclusion criteria was used among studies involving individuals with a history of ankle sprain with or without CAI, which could make it difficult to compare and generalize study results. This scoping review provides a baseline for planning future studies exploring outcome measures to assess sensorimotor function of individuals with a history of ankle sprain with or without CAI.

Acute Effect of Kinesiology Taping on Postural Stability in Individuals With Unilateral Chronic Ankle Instability

Background

Chronic ankle instability (CAI), which is characterized by deficient postural control, could be improved through kinesiology taping (KT). However, the effect of KT on postural control in CAI individuals is controversial. Therefore, this study aimed to investigate the acute effect of KT on postural control through computerized dynamic posturography (CDP) and self-perceived sensation in CAI individuals.

Methods

Participants with CAI received four different ankle treatments randomly, including KT, athletic taping (AT), sham taping (ST), and no taping (NT). A series of postural stability measurements was performed using CDP subsequently. The measurements included sensory organization test (SOT), unilateral stance (US), limit of stability (LOS), motor control test (MCT), and adaption test (ADT). In addition, self-perceived sensation was measured through visual analog scaling. Repeated measures analysis of variance was conducted to determine whether the difference among KT, AT, ST, and NT was significant; Bonferroni test was used for post hoc analysis.

Results

No significant difference was observed for parameters in SOT, US, and LOS in four different taping treatments. In MCT, the amplitude scaling scores of KT were 35.87% significantly lower than that of NT [p < 0.001, 95% confidence interval (CI) = 0.548–1.795] in forward-small slip and 21.58% significantly lower than that of ST (p = 0.035, 95% CI = 0.089–3.683) in backward-large slip. In ADT, sway energy scores were 7.59% significantly greater in ST than in AT (p = 0.028, 95% CI = −8.343 to −0.320). For perceived stability, KT was significantly greater than ST (p < 0.001, 95% CI = 0.552–1.899) and NT (p < 0.001, 95% CI = 0.797–2.534), and AT was significantly greater than ST (p = 0.001, 95% CI = 0.423–2.246) and NT (p < 0.001, 95% CI = 0.696–2.852). For perceived comfort, KT was significantly greater than AT (p = 0.001, 95% CI = 0.666–3.196) and NT (p = 0.031, 95% CI = 0.074–2.332), and ST was significantly greater than AT (p = 0.007, 95% CI = 0.349–2.931).

Conclusion

KT and AT have limited effect to facilitate postural control for CAI individuals during SOT, US, and LOS. However, KT and AT could provide effective support to cope with sudden perturbation in MCT and ADT. Moreover, KT provided excellent perceived stability and comfort, whereas AT provided excellent perceived stability but least comfort.

Differences in lower quarter Y-balance test with player position and ankle injuries in professional baseball players

PURPOSE

Although there has been research about the correlation between ankle injury and Y-balance test (YBT) conducted in other sports, there has been a lack of research on the correlation between ankle injury among baseball players and YBT scores or on differences in scores according to baseball positions. This study focused on professional baseball players as its subjects with the aims of analyzing the correlation between YBT and ankle injury and assessing differences in YBT between baseball positions.

METHODS

Age, height, weight, body mass index, and spine malleolar distance of 42 professional baseball players were measured. YBT measurements were performed using each foot in three distinct directions. YBT normalized reach distances, composite score, and reach asymmetry were analyzed.

RESULTS

The mean right posteromedial normalized reach distances for the player positions were significantly different between the pitchers (107.7%) and infielders (113.7%) ( p = 0.028). For the composite score, the difference between the pitchers (92.3%) and infielders (95.0%) was statistically significant ( p = 0.048). The anterior reach asymmetry was larger in the injured group than in the noninjured group ( p = 0.041).

CONCLUSION

This study shows that YBT can be used as a way of evaluating the injury of baseball players. It also shows the reference value of YBT according to position in professional baseball players. This study could be useful for the treatment of ankle injury of baseball players. Level of evidence: Level 3.

Do External Supports Improve Dynamic Balance in Patients with Chronic Ankle Instability? A Network Meta-analysis

BACKGROUND

To improve ankle stability in patients who have experienced an ankle sprain with residual symptoms of instability and/or objective joint laxity, external supports (such as taping, bracing, and orthotic insoles) are used sometimes. However, available randomized trials have disagreed on whether restraints improve balance in those individuals. In this situation, a network meta-analysis can help because it allows for comparing multiple treatments simultaneously, taking advantage not only of direct but also indirect evidence synthesis.

QUESTIONS/PURPOSES

The aim of this network meta-analysis was to assess (1) the impact of taping and orthotic devices on dynamic postural control in individuals with ankle instability and (2) the presence of a placebo effect in participants treated with sham taping and complications resulting from the administered treatments.

METHODS

We searched the PubMed, Scopus, and CENTRAL databases up to February 13, 2019 for completed studies. Randomized trials assessing the results of real and/or sham taping, wait-and-see protocols, ankle bracing, and foot orthotics for ankle instability as determined by one or more ankle sprains followed by ongoing subjective symptoms and/or mechanical laxity were included. We evaluated dynamic postural control in terms of the Star Excursion Balance Test in the posteromedial direction (SEBT-PM), which is considered the most representative of balance deficits in patients with ankle instability. Standardized mean differences were re-expressed to percentage differences in SEBT-PM, with higher scores representing possible improvement. Subsequently, those data were checked against the established minimal detectable change of 14% for this scale to make judgements on clinical importance. We also assessed the presence of a placebo effect by comparing the results of sham taping with no treatment and complications resulting from the administered treatments. Additionally, we judged the quality of trials using the Cochrane risk of bias tool and quality of evidence using the Grading of Recommendations, Assessment, Development, and Evaluations (GRADE) approach. A total of 22 trials met our inclusion criteria, 18 of which were deemed to be at a low risk of bias. A network of treatments consisting of 13 studies was created, and the level of evidence was judged to be high. As far as participants' allocation to treatment arms, 85 patients followed a wait-and-see protocol, 29 received placebo taping, 99 were treated with taping, 16 were treated with bracing, 27 were administered insoles, and six individuals were offered a combination of insoles with bracing. Of note, with statistical power set at 80%, a minimum of 16 patients per treatment group was required to provide sufficient statistical power and detect a SEBT-PM percentage difference of 14%.

RESULTS

A network meta-analysis did not demonstrate a benefit of taping or bracing over no treatment (percentage difference in SEBT-PM between taping and bracing versus control: -2.4 [95% CI -6 to 1.1]; p = 0.18, and -7.5 [95% CI -15.9 to 1]; p = 0.08, respectively). This was also the case for sham taping because the measurement increase failed to exceed the minimal detectable change (percentage difference in SEBT-PM between sham taping and untreated control: -1.1 [95% CI -6.9 to 4.7]; p = 0.72). Importantly, there were no reported adverse events after treatment application.

CONCLUSIONS

Evidence of moderate strength indicated that external supports of any type were no more effective than controls in improving dynamic postural control in patients with at least one ankle sprain and residual functional or mechanical deficits. Therefore, implementing those tools as a standalone treatment does not appear to be a viable strategy for the primary management of ankle instability. It is conceivable that combinations of rehabilitation and external supports could be more effective than external supports alone, and future trials should evaluate the potential of such combinations in enhancing not only clinician-reported but also patient-oriented outcomes using long-term follow-up measurements.

Comparison of effectiveness of different kinesiological taping techniques in patients with chronic low back pain: A double-blind, randomized-controlled study

Objectives

This study aims to investigate the effects of kinesiological taping (KT) method combined with physiotherapy modalities and exercise therapy on the severity of pain, range of lumbar motion, and degree of disability.

Patients and methods

Between November 2015 and November 2016, a total of 125 patients (63 males, 62 females; mean age 45 years; range, 20 to 65 years) who were diagnosed with chronic non-specific low back pain were included in this double-blind, randomized, placebo-controlled study. The patients were randomly assigned to four groups. All groups received the same physiotherapy modalities and exercise therapy. Group 1 received physiotherapy modalities and exercise therapy alone; Group 2 received additional sham KT; Group 3 received additional KT with a space correction technique; and Group 4 received additional KT with a fascia correction technique. Kinesiological taping was applied for three weeks with five-day intervals and four times in total. The patients were evaluated at baseline (Day 0), at the end of the treatment (Day 21), and on Day 51. Pain severity using the Visual Analog Scale (VAS), ranges of lumbar motion using the fingertip-to-floor distances and modified lumbar Schober test, and the degree of disability using the Oswestry Disability Index (ODI) and Roland Morris Disability Questionnaire (RMDQ) were evaluated.

Results

We found a significant difference among the groups in terms of VAS motion T0-51 changes (p<0.05). There was also a significant difference among the groups in terms of T0-21 and T0-51 changes in the ODI and RMDQ (p<0.05).

Conclusion

Our study results suggest that KT ensures reduction in pain and disability, irrespective of the technique of taping, with sustainable short-term effects following the end of the treatment.

Effect of Kinesio taping on Y-balance test performance and the associated leg muscle activation patterns in children with developmental coordination disorder: A randomized controlled trial

BACKGROUND

Children with developmental coordination disorder (DCD) have leg muscular deficits which negatively affects their dynamic postural stability. Kinesio tape (KT) could enhance muscle activation, postural control and functional activities in healthy individuals. Therefore, we hypothesized that the usage of KT may address the postural instability problem of children with DCD.

RESEARCH QUESTION

To investigate the immediate effect of KT on dynamic postural stability and the associated lower limb muscle activity in children with DCD.

METHODS

Forty-nine children with DCD were recruited where twenty-five children were randomly assigned to the KT group (mean age = 8.18 ± 1.16 years) and twenty-four to the control group (mean age = 8.06 ± 0.93 years). KT group received KT application to the rectus femoris and gastrocnemius muscles whereas the control group received no intervention. Measurements were taken before and after the application of KT. Dynamic balance performance was measured using a lower quartile Y-balance test (YBT-LQ). Leg muscle peak activation and time-to-peak muscle activation of the dominant lower limb during YBT-LQ were measured by surface electromyography.

RESULTS

YBT-LQ composite score increased by 6.3% in the KT group at posttest (95% CI: -7.308, -2.480). In addition, a higher rectus femoris peak activation was illustrated for YBT-LQ anterior (32.5%; 95% CI: -48.619, -16.395) and posteromedial (24.6%; 95% CI: -42.631, -6.591) reach directions from pretest values in the KT group. Moreover, KT group exhibited a 38% (95% CI: 0.015, 2.983) longer gastrocnemius medialis time-to-peak duration for YBT-LQ posteromedial reach direction when compared to the control group.

SIGNIFICANCE

KT revealed an immediate beneficial effect on YBT-LQ performance. Application of KT also increased rectus femoris peak activation and lengthened the muscle time-to-peak duration for specific reach directions. Incorporating KT as an adjunct with dynamic balance training programme could be beneficial for children with DCD.

Nonelastic and Kinesio Tex Tapes Improve Perceived Stability But Not Postural Control in Participants With Chronic Ankle Instability

The development of chronic ankle instability (CAI) is common following a lateral ankle sprain. Taping using nonelastic and Kinesio Tex (KT) tapes remain popular treatment strategies. The purpose of this investigation was to determine if KT tape improves static and dynamic postural control relative to nonelastic tape and a control condition. Twenty-four participants completed all three conditions. No immediate improvements in postural control were noted in either taping condition. Both nonelastic and KT tape improved perceived stability relative to the control condition. In conclusion, nonelastic and KT tape should not be used to immediately improve postural control in CAI participants.
