Effects of scapular taping on the activity onset of scapular muscles and the scapular kinematics in volleyball players with rotator cuff tendinopathy

Effects of elastic taping on kyphosis and body balance in the elderly: a randomized crossover study

Kyphosis produces abnormal posture and reduced body balance in the elderly. Elastic tape may be useful at improving kyphotic posture and body balance. This study aims to evaluate the effects of elastic taping on kyphosis and body balance in the elderly. Ten elderly participants with degenerative kyphotic posture were recruited and randomly assigned to two groups (back taped with stretched elastic tape for 15 min and back taped with non-stretched elastic tape for 15 min). After a 1-h washout period, the groups were swapped over to receive the other intervention. The outcomes measured after each taping technique were Cobb's angle measurement by inclinometer, perceived pain, and balance measurements by single leg stance test, time up and go test, center of gravity alignment (COG) and modified clinical test of sensory interaction on balance test (mCTSIB). There was a significant reduction in kyphotic angle and back pain in both the stretched and non-stretched taping groups (p < 0.05). We also found both taping techniques significantly reduced sway velocity on a foam surface with eyes closed and open (p < 0.05). However, there was no significant difference between taping groups for kyphotic angle, pain reduction or balance. The application of 15 min of stretched and non-stretched elastic tape in the elderly reduced kyphotic angle, back pain, and sway velocity while standing on foam surface in the mCTSIB test. If these changes persist over the long term (days and weeks) taping may be a useful intervention for elderly patients with kyphosis.

Shoulder Kinesio Taping Does Not Change Biomechanical Deficits Associated With Scapular Dyskinesis

Observable scapular dyskinesis is associated with biomechanical deficits. Preventative interventions aimed at correcting these deficits may aid in preventing the development and resolution of shoulder pain. Our purpose was to investigate the effects of kinesio taping (KT) on common biomechanical deficits associated with scapular dyskinesis and shoulder pain. Participants (n = 51) with observable scapular dyskinesis, and without shoulder pain were randomized to KT, KT-placebo, or a no-treatment control group. Measurements taken before, immediately after taping, and 3 days later included pectoralis minor muscle length, lower trapezius muscle strength, scapular upward rotation angle at 0° to 120° in scapular plane humeral elevation and acromiohumeral distance. There were no changes in scapular upward rotation, lower trapezius strength, and acromiohumeral distance immediately after taping or 3 days later compared to baseline (P > .05). The pectoralis minor increased in length in the KT group on day 3 compared to directly after taping (P = .03), but no difference between groups or interaction between time and group were determined (P > .05). Scapular dyskinesis prevalence did not change over time in any group (P > .05). In people with scapular dyskinesis free from shoulder pain, KT applied to the shoulder cannot be recommended to ameliorate the biomechanical deficits associated with shoulder pain.

Evidence for taping in overhead athlete shoulders: a systematic review

Taping is a popular approach and is often used as part of a multifactorial injury prevention programme for athletes. The aim of this study was to evaluate the current literature regarding the effects of shoulder taping in overhead athletes. Literature search was performed related to rotational range of motion (RoM), posterior shoulder tightness (PST), kinematics, muscular activity, acromiohumeral distance (AHD), proprioception, strength, and performance. Twenty studies were eligible. The majority of the applied taping methods were scapular and humeral head repositioning taping. Across all studies, there was limited to moderate evidence in favour of taping in overhead athletes with regard to rotational RoM, AHD, proprioception, and altering scapular kinematics, while taping did not enhance PST, muscular activity, shoulder strength, and performance. Therefore, the current evidence showed taping can alter some of the investigated factors that may have a therapeutic or preventive role. However, in the management of the athlete shoulder, taping-only approaches should not be focused on, and taping can be integrated in a more comprehensive approach for the overhead athletes.

Does scapular corrective taping alter periscapular muscle activity and 3-dimensional scapular kinematics? A systematic review

STUDY DESIGN

This is a systematic review.

INTRODUCTION

Scapular taping is widely used in the management of scapular dysfunction. However, its effects on the scapular kinematics and the electromyography (EMG) activity of the periscapular muscles are not clear.

PURPOSE OF THE STUDY

The purpose of the study was to systematically review the current literature to examine whether scapular corrective taping alters the EMG activity of the periscapular muscles and the 3-dimensional scapular kinematics.

METHOD

MEDLINE and Web of Science databases were searched using specific mesh terms up to April 2018. A hand search was also conducted on the reference list of the included articles. A total of 157 studies were identified, and they were further analyzed for the eligibility to the systematic review. Studies that investigated the effects of scapular corrective taping on the EMG activity of the periscapular muscles and on the 3-dimensional scapular kinematics on patients with shoulder problems or asymptomatic subjects were eligible for the systematic review. The Cochrane Effective Practice and Organization of Care criteria were modified and used for the risk-of-bias assessment.

RESULTS

Eleven articles met the inclusion criteria and were included in the systematic review. Five studies investigated the effects of corrective taping on the scapular kinematics and 8 studies reported the effects of corrective taping on the EMG activity of the periscapular muscles. There was an agreement among the studies that scapular upward rotation is increased with the corrective taping, while there are inconsistent results concerning the scapular external rotation and posterior tilt. In addition, studies mostly reported that corrective taping decreases the activity of the upper trapezius, while it has conflicting effects on the activity patterns of other periscapular muscles.

DISCUSSION

Scapular corrective taping was found to increase the scapular upward rotation; however, its effects on scapular external rotation and posterior tilt are controversial. It was also found that corrective taping might decrease the EMG activity of the upper trapezius, while it had no effects on the activity of lower trapezius, and its effects on other periscapular muscles were controversial.

CONCLUSION

The results of the studies indicated that scapular corrective taping might alter the 3-dimensional scapular kinematics, while there are controversies about the effects of corrective taping on the EMG activity of the periscapular muscles. Further studies are needed to clarify the conflicts.

Kinesio taping for rotator cuff disease

BACKGROUND

Kinesio Taping (KT) is one of the conservative treatments proposed for rotator cuff disease. KT is an elastic, adhesive, latex-free taping made from cotton, without active pharmacological agents. Clinicians have adopted it in the rehabilitation treatment of painful conditions, however, there is no firm evidence on its benefits.

OBJECTIVES

To determine the benefits and harms of KT in adults with rotator cuff disease.

SEARCH METHODS

We searched the Cochrane Library, MEDLINE, Embase, PEDro, CINAHL, Clinicaltrials.gov and WHO ICRTP registry to July 27 2020, unrestricted by date and language.

SELECTION CRITERIA

We included randomised and quasi-randomised controlled trials (RCTs) including adults with rotator cuff disease. Major outcomes were overall pain, function, pain on motion, active range of motion, global assessment of treatment success, quality of life, and adverse events.

DATA COLLECTION AND ANALYSIS

We used standard methodologic procedures expected by Cochrane.

MAIN RESULTS

We included 23 trials with 1054 participants. Nine studies (312 participants) assessed the effectiveness of KT versus sham therapy and fourteen studies (742 participants) assessed the effectiveness of KT versus conservative treatment. Most participants were aged between 18 and 50 years. Females comprised 52% of the sample. For the meta-analysis, we considered the last available measurement within 30 days from the end of the intervention. All trials were at risk of performance, selection, reporting, attrition, and other biases.  Comparison with sham taping Due to very low-certainty evidence, we are uncertain whether KT improves overall pain, function, pain on motion and active range of motion compared with sham taping. Mean overall pain (0 to 10 scale, 0 no pain) was 2.96 points with sham taping and 3.03 points with KT (3 RCTs,106 participants), with an absolute difference of 0.7% worse, (95% CI 7.7% better to 9% worse) and a relative difference of 2% worse (95% CI 21% better to 24% worse) at four weeks. Mean function (0 to 100 scale, 0 better function) was 47.1 points with sham taping and 39.05 points with KT (6 RCTs, 214 participants), with an absolute improvement of 8% (95% CI 21% better to 5% worse)and a relative improvement of 15% (95% CI 40% better to 9% worse) at four weeks. Mean pain on motion (0 to 10 scale, 0 no pain) was 4.39 points with sham taping and 2.91 points with KT even though not clinically important (4 RCTs, 153 participants), with an absolute improvement of 14.8% (95% CI 22.5% better to 7.1% better) and a relative improvement of 30% (95% CI 45% better to 14% better) at four weeks. Mean active range of motion (shoulder abduction) without pain was 174.2 degrees with sham taping and 184.43 degrees with KT (2 RCTs, 68 participants), with an absolute improvement of 5.7% (95% CI 8.9% worse to 20.3% better) and a relative improvement of 6% (95% CI 10% worse to 22% better) at two weeks. No studies reported global assessment of treatment success. Quality of life was reported by one study but data were disaggregated in subscales. No reliable estimates for adverse events (4 studies; very low-certainty) could be provided due to the heterogeneous description of events in the sample. Comparison with conservative treatments Due to very low-certainty evidence, we are uncertain if KT improves overall pain, function, pain on motion and active range of motion compared with conservative treatments. However, KT may improve quality of life (low certainty of evidence).  Mean overall pain (0 to 10 scale, 0 no pain) was 0.9 points with conservative treatment and 0.46 points with KT (5 RCTs, 266 participants), with an absolute improvement of 4.4% (95% CI 13% better to 4.6% worse) and a relative improvement of 15% (95% CI 46% better to 16% worse) at six weeks. Mean function (0 to 100 scale, 0 better function) was 46.6 points with conservative treatment and 33.47 points with KT (14 RCTs, 499 participants), with an absolute improvement of 13% (95% CI 24% better to 2% better) and a relative improvement of 18% (95% CI 32% better to 3% better) at four weeks. Mean pain on motion (0 to 10 scale, 0 no pain) was 4 points with conservative treatment and 3.94 points with KT (6 RCTs, 225 participants), with an absolute improvement of 0.6% (95% CI 7% better to 8% worse) and a relative improvement of 1% (95% CI 12% better to 10% worse) at four weeks. Mean active range of motion (shoulder abduction) without pain was 156.6 degrees with conservative treatment and 159.64 degrees with KT (3 RCTs, 143 participants), with an absolute improvement of 3% (95% CI 11% worse to 17 % better) and a relative improvement of 3% (95% CI 9% worse to 14% better) at six weeks.  Mean of quality of life (0 to 100, 100 better quality of life) was 37.94 points with conservative treatment and 56.64 points with KT (1 RCTs, 30 participants), with an absolute improvement of 18.7% (95% CI 14.48% better to 22.92% better) and a relative improvement of 53% (95% CI 41% better to 65% better) at four weeks.  No studies were found for global assessment of treatment success. No reliable estimates for adverse events (7 studies, very low certainty of evidence) could be provided due to the heterogeneous description of events in the whole sample.

AUTHORS' CONCLUSIONS

Kinesio taping for rotator cuff disease has uncertain effects in terms of self-reported pain, function, pain on motion and active range of motion when compared to sham taping or other conservative treatments as the certainty of evidence was very low. Low-certainty evidence shows that kinesio taping may improve quality of life when compared to conservative treatment. We downgraded the evidence for indirectness due to differences among co-interventions, imprecision due to small number of participants across trials as well as selection bias, performance and detection bias. Evidence on adverse events was scarce and uncertain. Based upon the data in this review, the evidence for the efficacy of KT seems to demonstrate little or no benefit.

Goal-Oriented Optimization of Dynamic Simulations to Find a Balance between Performance Enhancement and Injury Prevention during Volleyball Spiking

Performance enhancement and injury prevention are often perceived as opposite sides of a coin, where focusing on improvements of one leads to detriment of the other. In this study, we used physics-based simulations with novel optimization methods to find participant-specific, whole-body mechanics of volleyball spiking that enhances performance (the peak height of the hitting hand and its forward velocity) while minimizing injury risk. For the volleyball spiking motion, the shoulder is the most common injury site because of the high mechanical loads that are most pronounced during the follow-through phase of the movement. We analyzed 104 and 209 spiking trials across 13 participants for the power and follow-through phases, respectively. During the power phase, simulations increased (p < 0.025) the peak height of the hitting wrist by 1% and increased (p < 0.025) the forward wrist velocity by 25%, without increasing peak shoulder joint torques, by increasing the lower-limb forward swing (i.e., hip flexion, knee extension). During the follow-through phase, simulations decreased (p < 0.025) peak shoulder joint torques by 75% elicited by synergistic rotation of the trunk along the pathway of the hitting arm. Our results show that performance enhancement and injury prevention are not mutually exclusive and may both be improved simultaneously, potentially leading to better-performing and injury-free athletes.

Rehabilitation Management of Rotator Cuff Injuries in the Master Athlete

Rotator cuff (RTC) injuries are common in master athletes, especially overhead athletes. Risk factors include aging and degeneration as nonmodifiable and volume of activity, muscle weakness, and loss of motion as modifiable. The clinical presentation involves limited range of motion (ROM), pain at rest and at night. Injury classification into traumatic versus nontraumatic and tendinopathy, partial or full-thickness tears helps to establish a treatment plan. RTC injury rehabilitation protocols are criteria-based, multimodal, and divided into four phases. The acute phase addresses pain, inflammation, ROM, and RTC protection. The recovery phase addresses kinetic chain abnormalities, flexibility, and strength, and the functional phase involves exercises directed toward specific sport activities. Return to sports is based on clinical recovery, kinetic chain principles, and adequate sports technique. Nonsurgical management is recommended in most cases, and surgical management is considered if symptoms progress, especially for full-thickness tears.

The effects of proprioceptive neuromuscular facilitation lower-leg taping and treadmill training on mobility in patients with stroke

The elastic-taping method of the proprioceptive neuromuscular facilitation (PNF) concept is nonexistent. Therefore, our study aimed to investigate the effect of treadmill training (TT) using PNF lower-leg taping (PNFLT) on walking and balance ability in patients with stroke. There were a total of 27 patients: a stroke allocated control group (n=13) and an experimental group (n=14). The control group performed the TT and the experimental group performed the TT using PNF taping five times a week for 6 weeks. Walking and balance ability were measured using the 6-min walk test (6MWT), the 10-m walking test (10MWT), and the timed up and go test (TUG). Before and after the intervention, a paired t-test was performed to compare different within-group differences. Independent t-tests were performed to compare different between-group differences. All statistical significance levels were set at α of 0.05. After intervention, 6MWT, 10MWT and TUG improved significantly in PNFLT-TT and TT group (P<0.01). After intervention, the PNFLT-TT group showed more effective changes that the TT group in 6MWT, 10MWT, and TUG (P<0.05 and <0.01) between PNFLT-TT and TT group. The intervention of PNFLT-TT was effective in improving walking and balance ability in patients with stroke. Basic elastic tape for the PNF concept and TT may be useful interventions as a program to improve walking and balance ability in patients with stroke.

Taping to Improve Scapular Dyskinesis, Scapular Upward Rotation, and Pectoralis Minor Length in Overhead Athletes

CONTEXT

Deviations in scapular motions and subsequent alterations in associated soft tissues are thought to contribute to overuse shoulder injuries in overhead athletes. Whereas rigid and Kinesio taping are recommended for preventing these injuries, high-level evidence from clinical trials is still needed.

OBJECTIVE

To determine and compare the short-term effects of rigid and Kinesio taping on scapular dyskinesis, scapular upward rotation, and pectoralis minor length in asymptomatic overhead athletes.

DESIGN

Randomized controlled trial.

SETTING

Athletic training rooms.

PATIENTS OR OTHER PARTICIPANTS

Seventy-two elite asymptomatic overhead athletes (age = 17.00 ± 4.09 years, height = 1.75 ± 0.11 m, mass = 67.26 ± 15.25 kg, body mass index = 21.80 ± 3.00).

INTERVENTION(S)

We randomly assigned participants to 1 of 4 groups: rigid taping, Kinesio taping, placebo, or control (no taping). For the first 3 groups, we applied tape to the shoulder and scapular region.

MAIN OUTCOME MEASURE(S)

We evaluated all groups for observable scapular dyskinesis using the scapular dyskinesis test, scapular upward rotation using a digital inclinometer, and pectoralis minor length using the pectoralis minor index at baseline, immediately after taping, and at 60 to 72 hours after taping.

RESULTS

The scapular dyskinesis percentage ( P < .05) decreased and the pectoralis minor index ( P < .001) increased immediately and at 60 to 72 hours after taping in the rigid-taping and Kinesio-taping groups. We observed no differences among groups for the change in the pectoralis minor index ( P > .05). Scapular upward rotation did not change after taping in any group ( P > .05).

CONCLUSIONS

Rigid or Kinesio taping of the shoulder and scapular region improved scapular dyskinesis and pectoralis minor length but did not alter scapular upward rotation. Short-term rigid and Kinesio taping may help improve scapular dyskinesis and pectoralis minor length in overhead athletes.

Acute effect of elastic bandage technique on middle deltoid muscle force and activation in healthy men

Abstract Introduction: Elastic bandages (EB), such as Kinesio taping, have been widely used in sports or daily life activities with the aim of preventing or reducing musculoskeletal injuries. It has been suggested that Kinesio Taping is capable of altering muscle activation through neurophysiological mechanisms, but the evidences about this are controversial. Objective: To verify the acute effect of EB on maximum voluntary isometric force (MVIF) and muscle activation of the middle deltoid muscle during muscle contraction. Method: Twenty-four healthy male (24 ± 4 years, 73.2 ± 13.9kg, 1.80 ± 0.10m) were randomly assigned to a group with elastic bandage activated at 100% (AEB n = 8); with tensionless elastic bandage (NEB n = 8), and the control group (CG n = 9). The volunteers were instructed to perform 5s of maximal isometric contraction at 90° of shoulder abduction while the MIVF and EMGrms records were registered. Results: One-way ANOVA was unable to identify significant difference (α = 0.05) in MIVF and EMGrms of the middle deltoid at 90° of shoulder abduction. Conclusion: The application of elastic bandage was not able to alter the production of maximal isometric voluntary contraction and activation of the middle deltoid muscle of healthy individuals and, therefore, its use is not justified for these purposes.

The Effects of Rigid Scapular Taping on the Subacromial Space in Athletes With and Without Rotator Cuff Tendinopathy: A Randomized Controlled Study

CONTEXT

Reduction of the subacromial space (SAS) during arm elevation may contribute to rotator cuff (RC) tendinopathy. The effects of scapular taping on the SAS in athletes with and without RC tendinopathy are unknown.

OBJECTIVE

To investigate the immediate effects of scapular taping on the SAS in athletes with and without RC tendinopathy.

DESIGN

Randomized controlled study with repeated measures.

SETTING

University laboratory.

PARTICIPANTS

A total of 43 male volleyball players (17 asymptomatic and 26 with RC tendinopathy, mean age = 22.9 [3.5] y) participated in the study.

INTERVENTION

Three scapular taping protocols-no taping (control), taping with tension (therapeutic taping), and taping without tension (sham taping).

MAIN OUTCOME MEASURES

Ultrasound measurements of the SAS with the arm at 0° and 60° of shoulder abduction, and the change in the SAS between 0° and 60° of shoulder abduction (SAS_0°-60°) were calculated.

RESULTS

Athletes with RC tendinopathy demonstrated larger SAS with therapeutic taping at 60° of shoulder abduction (6.9 [1.9] mm vs 5.8 [1.7] mm, mean difference = 1.1 mm, 95% confidence interval, -1.80 to -0.39, P = .002) when compared with the no taping condition. The tendinopathy group also showed less reduction in the SAS with therapeutic taping during SAS_0°-60° (2.0 [1.4] mm vs 2.8 [1.4] mm, P = .02) when compared with the no taping condition. When tape was applied to the scapula in asymptomatic athletes, our results showed a relatively small increase in the SAS with therapeutic taping during arm resting at 0° of abduction when compared with the no taping condition (8.7 [0.9] mm vs 8.3 [0.8] mm, mean difference = 0.4 mm, 95% confidence interval, -0.71 to -0.11, P = .01).

CONCLUSIONS

Athletes with RC tendinopathy demonstrated less reduction of the SAS with rigid scapular taping during early arm abduction. Such observation was not evidenced in asymptomatic athletes.
