Kinesiotaping for postoperative oedema – what is the evidence? A systematic review

Abstract

Background

Postoperative oedema is a common condition affecting wound healing and function. Traditionally, manual lymphatic drainage is employed to reduce swelling. Kinesiotaping might be an alternative resource-sparing approach. This article explores current evidence for the effectiveness of kinesiotaping for the reduction of oedema in the postoperative setting.

Methods

A systematic literature search was performed on the basis of five databases (Pubmed, CINAHL, Embase, Cochrane Library, and Clinicaltrials.gov) for studies published between January 2000 and October 2019.

Only prospective controlled trials were included. Case studies, uncontrolled case series, studies on oedema caused by other etiologies than by surgery, as well as studies on malignant disease related oedema (especially breast cancer related oedema) were excluded.

Articles were screened by title, abstract, and full text and the references were searched for further publications on the topic. A narrative and quantitative (using STATA) analysis was performed.

Results

One thousand two hundred sixty-three articles were screened, twelve were included in the analysis. All studies evaluated either oedema after extremity surgery or maxillofacial interventions, and showed relevant methodological flaws. Only three studies employed an active comparator. Of the twelve included studies ten found positive evidence for kinesiotape application for the reduction of swelling and beneficial effects on secondary outcome parameters such as pain and patient satisfaction. The available trials were heterogenic in pathology and all were compromised by a high risk of bias.

Conclusion

There is some evidence for the efficacy of kinesiotaping for the treatment of postoperative oedema. This evidence is, however, not yet convincing given the limitations of the published trials. Methodologically sound comparison to standard of care or an active comparator is indispensable for an evaluation of effectiveness. In addition, assessments of patient comfort and cost-benefit analyses are necessary to evaluate the potential relevance of this novel technique in daily practice.

Background

Oedema is a pathologic condition characterized by an accumulation of fluid in the interstitium, leading to local or generalized swelling. Oedemas are differentiated in primary (a systemic and often idiopathic abnormality) and secondary oedemas (an external cause leading to venous and/or lymphatic insufficiency). Secondary oedema can be caused by a variety of reasons, such as cancer, heart failure, or trauma. Surgery is also a common cause of secondary oedema [1, 2].

Traditionally, decongestive measures, including manual lymphatic drainage and compression treatment using complex multi-layer bandaging or compression stockings, as well as skin care and decongestive exercise, have been established for the treatment of oedemas [2–4].

Recently though, kinesiotaping has gained some attention in this context. The principle was developed by the Japanese chiropractor Kenzo Kase in the seventies, and has been popularized in Europe since the nineties [2, 5, 6]. A kinesiotape is an elastic tape usually made of cotton, which contains longitudinal interwoven elastic fibers and acrylic glue that is spread in a wavelike pattern. The material has an elasticity of approximately 130–140%, and is applied to the skin using a certain amount of traction, thereby influencing the skin and various subcutaneous layers [5, 7].

Many different indications for the use of kinesiotape have been proposed, such as influencing the muscular tone, supporting joint functions, affecting pain perception, and reducing swelling [5]. Regarding the treatment of oedema, several mechanisms of action are being discussed: The pre-tension of the tape subtly lifts the skin, thereby possibly improving the lymphatic flow and directing it to pathways that suffer less congestion [5]. Furthermore, the tape is assumed to provide a massage-effect during active movement [8].

Currently there are only few individual and heterogeneous trials and there is no systematic review exploring kinesiotape application for the treatment of postoperative edema independent of malignancy. The investigation reported in this article therefore aims at evaluating the current evidence to determine the state of research and the evidence for an efficacy or effectiveness of this approach following the PICOS scheme with an analysis of participants, interventions, comparisons, outcomes, and study design. This question is of relevance since superiority or even non-inferiority of kinesiotaping in the treatment of postoperative oedema might allow a change in standard management, which in turn could liberate health care professionals from resource-intensive lymphatic drainage to other important tasks like mobilization, instruction etc.

Methods

Types of studies

We conducted a systematic literature search to identify existing studies presenting original empirical research on the use of kinesiotape for the treatment of postoperative oedema following a predefined project plan (PROSPEROID 114129). The actual type of index-surgery was irrelevant as in- or exclusion criterion.

Types of participants

We included prospective controlled studies published in English, German or French involving adult participants who were treated with kinesiotaping for postoperative oedema. We excluded studies analyzing the effect of kinesiotaping for oedema associated with malignancy or studies evaluating possible kinesiotape-mediated effect on muscular tonus. Equally animal studies were excluded.

Types of interventions

Kinesiotaping for the treatment of postoperative oedema was defined as wavy application of thin kinesiotape stripes converging at lymphatic drainage centres. The type of taping was identified following the authors’ descriptions or images in the publications. Studies that stated lymphtaping but described or depicted other types of kinesiotape application were excluded. We included studies that compared kinesiotaping for the treatment of postoperative oedema to a) no specific or sham treatment, b) manual lymphatic drainage, or c) pneumatic compression.

Types of outcome measures

Outcomes of interest were the reduction in swelling i.e. reduction in leg circumference or facial surface, pain, function, patient satisfaction and side effects, both at specific time points or with respect to the temporal course. No primary outcome was defined a priori. The plan was to analyze all outcomes reported in the majority of studies in a comparable manner.

Search methods for identification of studies

Five databases (Pubmed, CINAHL, Embase, Cochrane Library, and Clinicaltrials.gov) were searched for published and unpublished articles. For the Cochrane Library the Cochrane Database of Systematic Reviews, the Cochrane Central Register of Controlled Trials (CENTRAL) and Cochrane Clinical Answers were searched. The search included studies that were published between January 2000 and October 2019. The exact search string for each database is reported as supporting information (S1). An overviewing search of the years 1990–1999 did not yield any publications matching the above stated inclusion criteria.

Systematic reviews on kinesiotape in general were explicitly included in the search and clearing process, in order to check for additional original articles. Also, the references of the included studies as well as the citations of these studies according to the WebOfScience were checked.

Data collection and analysis

Study selection and data abstraction

Selection and data abstraction followed van Tulder et al. [9]. Two reviewers (JH and FJS) assessed the studies for eligibility screening title and abstract. Ambiguous studies were discussed in a group of three researchers (JH, FS, and WV). For articles meeting the above described inclusion criteria, full-texts were assessed for the pre-specified aspects listed in Table 1. The PICO (population, intervention, comparison, outcome) scheme was used to extract data of interest: Population characteristics comprised inclusion criteria, the average age, the gender ratio and the type of intervention. Intervention characteristics included the method of taping, the duration of treatment and the type of additional treatments equal for both groups (see below). The control intervention included active alternative treatments like lymphatic drainage or pneumatic compression, no treatment and/or sham treatment. In all studies all patients received additional supportive treatments like anti-inflammatory medication, application of cold, physiotherapy for mobilization etc. independently from their allocation to intervention- or control-group. Outcome measures included data on the course of swelling, pain levels, function, aspects of patient satisfaction and side effects. Data were extracted and documented without a specific software.

The assessment of quality followed Higgins et al. [10] analyzing the risk of allocation bias due to randomization or allocation concealment, the risk of performance bias in the context of blinding, the risk of detection bias minimized by blinded assessment of the main outcomes, attrition bias due to incomplete outcome data and reporting bias in the context of selective reporting. The reviewers were aware of the original authors, institutions and journals for reasons of feasibility. Authors could be contacted to clarify or provide additional information if the study provided insufficient information.

Data analysis

For a qualitative analysis, key aspects of the studies were extracted and tabulated and the main study findings were summarized verbally. For a quantitative analysis, only the degree of swelling satisfied the predefined criteria for outcome selection. Swelling was reported as (mean) circumferences/diameters (or related measures) at time points varying substantially from study to study. Many studies reported several outcome variables related to swelling without specifying a primary outcome. We hence extracted all corresponding data from all articles, aiming at computing the difference in mean values and a confidence interval at each time point reported. For eight studies, we could extract the standard deviations and sample sizes in each arm. For the study by Windisch et al. [11], we deduced standard errors from a graphical visualization of the confidence intervals of the mean values in each arm. For the study by Bialoszewski et al. [12], we made use of the p-values of a paired t-test comparing follow-up values with baseline values. For the study of Boguszewski et al. [13], we could not find sufficient information to compute confidence intervals. For the study by Balki et al. [14], the authors provide the mean and standard deviation values on our request.

We present the results from each study by plotting the observed difference in mean values with a 95% confidence interval at each time point. We should note that the outcomes are conceptually, but not necessarily numerically comparable. In addition, for most studies it was impossible to consider effect sizes for change scores, as the information was insufficient. Both aspects together prevent us from performing a formal meta-analysis and to assess the risk of publication bias.

Registration

The review was registered with PROSPERO (ID 114129).

Results

A total of 1263 articles were identified by our search strategy after removal of duplicates. These were screened by title, abstract, and, if potentially qualifying, by full text. We identified ten studies for analysis. Both the references within these publications and the citations of these studies allowed identifying three further studies. Finally, twelve studies were consistent with the pre-defined criteria. A flow diagram of the screening process is presented in Fig. 1. No previous systematic review considering kinesiotape as a treatment for postoperative oedema etiologically independent of malignancy could be identified.

Quantitative analysis

The only quantitative outcomes that were assessed in a conceptually comparable way across the majority of studies were the extent of swelling and pain. Since the choice of pain scales and numerical reporting practice for pain varied considerably, only the degree of swelling qualified as criterion for a quantitative analysis in all twelve studies. Figure 2 presents differences in mean values between the intervention groups and the control groups for the outcome variables related to swelling from all studies.

Fig. 2.

Differences in Swelling. Difference in mean values (black points) between the kinesiotape group and the control group for all outcome variables directly assessing the degree of swelling and for all time points reported in the studies. Negative differences indicate better outcomes under kinesiotape. In the studies of Donec et al. [22] and Ristow et al. [16, 19, 20] and for day 5 in the study of Bialoszewski et al. [12] results are based on change scores, in all other studies raw measurements are used as input. Most studies report a circumfence or diameter as outcome. For the study by Windisch et al. [11] we use the score from a “Principal Component Analysis2 based on eight different circumferences and omitted the eight single outcomes. For the maxillo-facial evaluaions, the three studies by Ristow et al. [16, 19, 20] use the sum of five predefined line lengths in the face, the study of Tozzi et al. [21] a volume based on a MakerBot® Digitizer 3DTM in cm³.95% confidence intervals (red lines) are shown when sufficient information was provided in the studies. They are truncated at − 5 or 5, as indicated by arrows. The green line refers to no difference between the two groups. The x-axis refers to time in days and is square root transformed. Results for differences at baseline are marked in gray. Studies are indicated by the name of the first author and the year of the publication

cf.: circumference.

Over all studies and all outcome variables, we observe a majority of negative differences when excluding very early assessments. This means less swelling with additional kinesiotape treatment compared to control treatment only. The only distinct exception is the study by Windisch et al. [11]. Four studies provide rather clear statistical evidence for an advantage of kinesiotaping: the study of Tozzi et al. [21] considering a single outcome, and the studies by Ristow et al. [16, 19, 20] which indicate an increasing difference over time, reaching significance at day 2 the latest. Also in the study by Donec et al. [22], we can recognize significant differences concerning three of the four outcomes at several follow-up time points, in the study of Gülenc [17] for two of four outcomes at several time points, and in the study of Balki et al. [14] for two outcomes on day 10.

Side effects

Five studies stated no adverse effects of taping; two studies reported of one (1/25 [17],) and two (2/35 [15],) patients respectively having had a skin reaction that lead to an interruption in treatment. The other studies did not comment on kinesiotape related complications.

Discussion

Summary of results

We could identify 12 studies comparing kinesiotaping for the management of postoperative oedema to other management options in a variety of patient populations. Eleven of these studies were RCTs. Estimates of the difference in swelling between the treatment groups suggested a beneficial effect of kinesiotape in many studies. However, the statistical significance of the findings in the single studies was varying and remained often unclear. It was not possible to conduct a formal meta-analysis, as the swelling was measured at different body parts and by different techniques. Furthermore, all studies were affected by a high risk of bias. Another recent trial has not yet been published but results from a conference abstract imply a significant reduction of pain and oedema after both kinesiotaping and MLD compared to control after total knee replacement [23]. The trial could not be included in the review since detailed data were not available upon request from the author.

An evaluation of the effectiveness was hampered be the fact that only three studies [11, 13, 22] involved an active comparator, two of them a pneumatic compression system and one manual lymphatic drainage. The study by Bialoszewski et al. [12] as the only one comparing kinesiotaping to manual lymphatic drainage as current gold standard suffers from methodologic flaws and lacks a description of the patient population or a comparison of the two groups. Also, our quantitative analysis of this study indicates no clear treatment effect. This leaves the studies by Donec et al. [22] and Windisch et al. [11] that share a similar patient population and active comparator. Unfortunately, their conclusions are conflicting. Hence, the evidence on which to base the recommendation of kinesiotaping for the treatment of postoperative oedema is rather limited.

Risk of bias

The risk of bias is displayed in Fig. 3 as proposed by Higgins et al. [10]. Performance bias cannot be excluded, as none of the studies used an adequate sham–taping as control, hence blinding of participants and personnel was impossible. Balki et al. [14] describe sham taping with a broad strip of non-tensioned kinesiotape on the anterior and posterior distal thigh. An adequate sham-control though should visually imitate the treatment under investigation without exerting its potential effect. The studies by Gülenç et al. [17, 18] did compare kinesiotaping to a sham-taping that indeed seems to have mimicked the application technique (at least in the area of the shoulder [18], no further information has been available in the article or after contacting the author on the sham-taping around the knee), but used a tape clearly different from kinesiotape by texture and appearance [18].

Fig. 3.

Risk of bias assessment. ¹ random sequence generation: none of the articles described random sequence generation in detail. The study by Bialoszewski et al. [12] is affected by an even higher risk since patients were not randomized primarily but only if they developed oedema during treatment. Chan et al. [21] recruited patients with and without meniscal surgery which might be medically reasonable but is methodologically disputable. Windisch et al. [11] performed no randomization but used a historical control. Gulenc et al. [17] describe randomization “ based on the rank of admission” in their study on kinesiotaping after knee arthroscopy. ² Allocation concealment is not described or doubtful (picking of envelopes)

³ Blinding of participants and personnel is not feasible in this context since the effect of sham taping with an alternative material has not been explored and control treatment like manual lymphatic drainage or intermittent pneumatic compression cannot be concealed either. ⁴ All but one articles fail to mention a blinding of the assessor, only Donec et al. [22], Ristow et al. [16, 19, 20] and Tozzi et al. [21] name the assessor. Balki et al. [14] describe a separation of assessor and researcher. ⁵ Bialoszewski et al. [12] miss to report the exact duration of treatment as well as the exact timing of assessment, Chan et al. do not mention the exact timing of assessments. Donec et al. [22] fail the reporting of basic measurements preoperative and retrospectively retrieve data on use of analgesics from patients’ charts. Tozzi et al. [21] do not report the beginning of treatment.

⁶ In spite of the overall high risk of bias in all the studies a tendency for selective reporting cannot be observed.

All studies failed to report blinding of the assessor. Only one accurately described the random sequence generation, and none choose more reliable randomization tools than sealed envelopes. Only four studies specified a primary outcome.

Besides these threads to the internal validity of the study, the external validity was also questionable: only one study used the current standard of care (manual lymphatic drainage) as comparator, only another two used an alternative active comparator. The information on the patient population was insufficient in all studies. The comparability of the studies additionally suffered from the variation in outcome measures and in follow-up time points.

The broader context

When interpreting the results, studies from maxillofacial surgery and extremity surgery should be separated. Ristow et al. [16, 19, 20] describe a standardized postoperative regimen with non-steroidal antiphlogistic medication as analgesic medication with influence though on inflammation and swelling, as well as and application of cooling measures. Tozzi et al. [21] used the application of perioperative dexamethasone and cooling as antiphlogistic treatment. Analgesic treatment is not reported by Tozzi et al. [21], seems probable though with potential influence on oedema development and resorption. Manual lymphatic drainage for the treatment of oedema after maxillofacial surgery does not seem as popular as in other fields of surgery. There are, however, publications that could show its benefit [24–26], and one ongoing trial is evaluating its clinical relevance [27]. Two studies – not included in this review due to the lack of control group in one and the lack of detailed information from a conference abstract in the other– state a benefit of kinesiotape application after penile surgery [28, 29], emphasizing the advantageous versatility of the technique that is adaptable to various anatomic regions. One additional study that lacked a control group and was therefore equally excluded in this review concludes a benefit of kinesiotaping after orthognatic surgery for the reduction of postoperative swelling [30].

Considering extremity surgery, manual lymphatic drainage is broadly accepted for the treatment of postoperative and posttraumatic oedema [31–33] as well as oedema caused by other pathologies [2, 29, 30], even though corresponding evidence is conflicting [3, 4, 34, 35]. The application of pneumatic compression was also established as treatment option [36–38], although again with limited evidence base [38–41]. Kinesiotaping might be yet another approach for the treatment of oedema. Animal experiments have shown effects on the development of oedema, the dermal structure [7], and lymphatic flow [8]. Indeed, the morphology of hematoma after application of kinesiotape (see Fig. 4) implies some effect. Whether this effect is of clinical relevance compared to other treatment modalities, the optimal technique, and treatment duration remains, however, unclear.

Fig. 4.

Kinesiotape application. Clinical effect of kinesiotape application in an elderly patient with an extensive hematoma of the right upper extremity (a). After kinesiotape application (b) and removal (c) signs of resorption can be noted at the former location of kinesiotape

The treatment of oedema remains an important aspect of postoperative therapeutic regimen, especially since oedema can negatively impact function and wellbeing. In addition, oedema have been found to be associated with prolonged wound healing and infections [42–44].

Given the high costs for personnel and the durability of up to 5 days of kinesiotaping, kinesiotaping is an inexpensive form of treatment compared to manual lymphatic drainage. It seems to be well accepted by most patients, and its application probably has benefits for the patient. Skin reactions are well possible, as also reported for three patients (of > 200 patients in all trials treated with kinseiotape) in our investigation., In general, kinesiotaping might be considered an alternative treatment of postoperative oedema which optimizes resources without jeopardizing the patients’ recovery.

Future research

There is an obvious need for more trials in well-defined patient-populations, covering specific indications and treatment aspects (ROM (range of motion), oedema, muscle strength, pain, etc.) while minimizing the risk of bias. Active comparators should be chosen that reflect the current standard, and a primary outcome directly related to swelling (or respective pathologies) should be predefined. Swelling is well suited as primary outcome, as it is relevant for the patient due to causing discomfort or even pain and simultaneously reflects the clinical target of the intervention. All studies included in our review suggest that an effect is visible after 7 days and does not increase later, suggesting 7 days as reasonable follow-up time point. Secondary outcome variables like pain, function, and wound-healing should also be addressed systematically and not least the cost-benefit ratio. In addition, a later time point might be chosen for an assessment of the clinical outcome via patient reported outcome measures (PROMS), occurrence of complications, and return to previous activities of daily living.

Conclusions

In conclusion, there are many RCTs suggesting a positive effect of kinesiotape application on postoperative swelling in a variety of indications. There is today, however, a lack of solid evidence with respect to its effectiveness that could support a recommendation of this practice. Larger randomized controlled trials for each specific indication will be necessary for the generation of solid evidence. Kinesiotape could have a relevant impact on clinical practice and health care expenditure if indeed a similar efficacy compared to MLD as current standard of care could be demonstrated.
