Intermittent compression for the treatment of the oedematous hand in hemiplegic stroke: a randomized controlled trial

Randomized Controlled Trial of Compression Interventions for Managing Hand Burn Edema, as Measured by Bioimpedance Spectroscopy

Compression, a common treatment of choice for the management of edema, is one intervention that is applied with little objective understanding of the optimal parameters of application or efficacy in acute burn wounds. The aim of this study was to determine the effectiveness of different methods of compression for the management of hand edema following burn injury. The primary hypothesis tested was that in acute hand burn injury, the application of cohesive bandage will reduce edema faster than a generic compression glove. It is a randomized controlled study of 100 patients presenting with hand burn injury. Compression was randomized to one of the three methods of application: 1) spiral application of Coban to fingers, figure of eight to hand and wrist; 2) pinch application of Coban to fingers, spiral application to hand and wrist; or 3) a generic compression glove (control condition). Bioimpedance spectroscopy was used to measure hand volumes. Hand and wrist range of movement, pain scores, and QuickDASH were recorded. One hundred patients (68 males) demonstrated significant reductions in hand volumes, using all compression methods. Both methods of applying Coban resulted in significantly greater reductions in edema compared to the generic compression glove. Notwithstanding compression method, all range of movement measures improved, with significant improvement in thumb opposition (P = .046), hand span (P = .020), and wrist flexion (P = .020). QuickDASH decreased between sessions (P < .001). Different methods of applying Coban are superior to generic compression gloves for managing acute hand burn edema.

[S1 guideline on intermittent pneumatic compression (IPC)]

Under the direction of the German Society of Phlebology (Deutsche Gesellschaft für Phlebologie) and in cooperation with other specialist associations, the S1 guideline on intermittent pneumatic compression (IPC) was adopted in January 2018. It replaces the previous guideline from March 2005. The aim of the guideline is to optimize the indication and therapeutic use of IPC in vascular diseases and edema. An extensive literature search of MEDLINE, existing guidelines, and work relevant to the topic was performed. In view of the often methodologically weak study quality with often small numbers of cases and heterogeneous treatment protocols, recommendations can often only be derived from the available data using good clinical practice/expert consensus. Intermittent pneumatic compression is used for thromboembolism prophylaxis, decongestive therapy for edema, and to positively influence arterial and venous circulation to improve clinical symptoms and accelerate ulcer healing in both the outpatient and inpatient care setting. The therapy regimens and devices used depend on the indication and target location. They can be used as outpatient and inpatient devices as well as at home for long-term indications. A target indication is thrombosis prophylaxis. IPC should be used in severe chronic venous insufficiency (stages C4b to C6), in extremity lymphedema as an add-on therapy and in peripheral arterial occlusive disease (PAOD) with stable intermittent claudication or critical ischemia. IPC can be used in post-traumatic edema, therapy-resistant venous edema, lipedema and hemiplegia with sensory deficits and edema. Absolute and relative contraindications to IPC must be taken into account and risks considered and avoided as far as possible. Adverse events are extremely rare if IPC is used correctly. If the indication and application are correct-also as an add-on therapy-it is a safe and effective treatment method, especially for the treatment of the described vascular diseases and edema as well as thrombosis prophylaxis.

Handgrip exercise by the non-affected hand increases venous return in the contralateral axillary vein in patients with stroke: a pilot study

Objective

Treatment of hand edema is important for maintaining upper limb function in patients with stroke, although the effects of many such treatments have been limited. This study aimed to examine, using ultrasound, the effect of handgrip exercise by the non-affected hand of stroke patients on venous return in the affected upper limb.

Results

Seven men participated, within 6 months of a unilateral first-ever stroke. With the patient supine, examinations were performed on the axillary vein of the affected side. The diameter and flow velocity of the axillary vein on the affected side were measured during two regimens: at rest or during rhythmic resistance exercise (30% of maximum grip strength for 20 s) performed by the non-affected hand. The venous flow volume in the axillary vein was then calculated using the data obtained. During resistance exercise by the non-affected hand, there were significant increases in both venous flow velocity (p = 0.01, d = − 0.80) and volume (p = 0.01, d = − 0.74) on the affected side, compared with baseline. The present preliminary study found that rhythmic resistance exercise with the non-affected hand increased venous flow velocity and volume in the affected upper limb of patients with stroke.

Effectiveness of edema management techniques for subacute hand edema: A systematic review

STUDY DESIGN

Systematic review.

INTRODUCTION

Prolonged hand edema can have detrimental effects on range of motion and function. There is no consensus on how best to manage traumatic subacute edema. This is the first systematic review which examines the clinical effectiveness of edema treatments on hand volume.

PURPOSE OF THE STUDY

The purpose of this systematic review was to examine the evidence of effectiveness of treatments for sub-acute hand edema.

METHODS

A literature search of AMED, CINAHL, Embase, and OVID MEDLINE (from inception to August 2015) was undertaken. Studies were selected if they met the following inclusion criteria: randomized controlled or controlled trials in adults who have subacute swelling after a recent upper limb musculoskeletal trauma or cerebral vascular attack or after surgery. Two independent assessors rated study quality and risk of bias using the 24-point MacDermid Structured Effectiveness Quality Evaluation Scale (SEQES).

RESULTS

Ten studies met the inclusion criteria. Study quality ranged from 23 to 41 out of 48 points on the SEQES. A total of 16 edema interventions were evaluated across the studies. Due to heterogeneity of the patient characteristics, interventions, and outcomes assessed, it was not possible to pool the results from all studies. Therefore, a narrative best evidence synthesis was undertaken. There is low to moderate quality evidence with limited confidence in the effect estimate to support the use of manual edema mobilization methods in conjunction with standard therapy to reduce problematic hand edema.

CONCLUSION

Manual edema mobilization techniques should be considered in conjunction with conventional therapies, in cases of excessive edema or when the edema has not responded to conventional treatment alone; however, manual edema mobilization is not advocated as a routine intervention.

Rehabilitation Interventions for Upper Limb Function in the First Four Weeks Following Stroke: A Systematic Review and Meta-Analysis of the Evidence

OBJECTIVE

To investigate the therapeutic interventions reported in the research literature and synthesize their effectiveness in improving upper limb (UL) function in the first 4 weeks poststroke.

DATA SOURCES

Electronic databases and trial registries were searched from inception until June 2016, in addition to searching systematic reviews by hand.

STUDY SELECTION

Randomized controlled trials (RCTs), controlled trials, and interventional studies with pre/posttest design were included for adults within 4 weeks of any type of stroke with UL impairment. Participants all received an intervention of any physiotherapeutic or occupational therapeutic technique designed to address impairment or activity of the affected UL, which could be compared with usual care, sham, or another technique.

DATA EXTRACTION

Two reviewers independently assessed eligibility of full texts, and methodological quality of included studies was assessed using the Cochrane Risk of Bias Tool.

DATA SYNTHESIS

A total of 104 trials (83 RCTs, 21 nonrandomized studies) were included (N=5225 participants). Meta-analyses of RCTs only (20 comparisons) and narrative syntheses were completed. Key findings included significant positive effects for modified constraint-induced movement therapy (mCIMT) (standardized mean difference [SMD]=1.09; 95% confidence interval [CI], .21-1.97) and task-specific training (SMD=.37; 95% CI, .05-.68). Evidence was found to support supplementary use of biofeedback and electrical stimulation. Use of Bobath therapy was not supported.

CONCLUSIONS

Use of mCIMT and task-specific training was supported, as was supplementary use of biofeedback and electrical simulation, within the acute phase poststroke. Further high-quality studies into the initial 4 weeks poststroke are needed to determine therapies for targeted functional UL outcomes.

Rehabilitation Interventions for Poststroke Hand Oedema: A Systematic Review

Objective/Background

To review the evidence of rehabilitation interventions for the management of poststroke hand oedema.

Methods

We conducted a systematic review of research articles in electronic databases published in English between 1999 and 2015. Two investigators working independently retrieved articles from the Cochrane Central Register of Controlled Trials, SCOPUS, Taylor & Francis Online, Wiley Online Library, CINAHL, Springer (MetaPress), ScienceDirect, PubMed, SAGE Journals Online, EBSCO, and Web of Science. Only controlled trials with outcome measures and interventions for poststroke hand oedema were included. Three investigators critically appraised the selected studies using the Physiotherapy Evidence Database Scale.

Results

Of the 189 articles identified, nine (5 randomized controlled trials, 3 nonrandomized controlled trials, and 1 crossover controlled trial) were selected. These studies are heterogeneous in terms of design and types of intervention for poststroke hand oedema. The interventions reducing hand oedema are Lycra pressure garments with glove splints, bilateral passive motion upper-limb exercises, laser therapy, and acupressure. However, due to these studies’ short intervention periods and the fact that hand oedema is not their primary outcome measure, it is not possible to draw a firm conclusion on their clinical significance for managing poststroke hand oedema.

Conclusion

Further study needs to focus solely on interventions for poststroke hand oedema and their long-term effects. No conclusion can be made on the most effective management of poststroke hand oedema until much more evidence is available.

Efficacy of Compression Gloves in Maintaining Edema Reductions After Application of Compression Bandaging to the Stroke-Affected Upper Limb

OBJECTIVE

We explored the efficacy of compression gloves in maintaining the benefits gained from compression bandaging of the stroke-affected upper limb.

METHOD

Four participants completed a single-case (ABC) design study consisting of a baseline period (Phase A) and compression bandaging of the hand and upper limb (Phase B), followed by the application of a compression glove (Phase C). Edema was measured with circumferential tape at five specified points from the phalanx to the midforearm. All measurements were represented graphically for visual analysis, and celeration lines were calculated to indicate the degree of slope within each phase.

RESULTS

Visual analysis indicated fluctuating edema volume during Phase A, decreasing edema volume during Phase B, and a mixed trend during Phase C.

CONCLUSION

Compression gloves had mixed benefits in managing reductions in edema volume poststroke. Further research may consider the material, sizing, and style of glove in the development of a maintenance strategy.

Single-case design evaluation of compression therapy for edema of the stroke-affected hand

OBJECTIVE. To explore the efficacy of low- and high-stretch compression bandaging for edema management in the stroke-affected upper limb. METHOD. A single-case, ABA-design study was conducted with 8 participants alternately allocated to receive low- or high-stretch bandaging. Edema was measured with circumferential tape at four specified points from the hand to the mid-forearm. All measurements were represented graphically for visual analysis, and celeration lines were calculated to indicate the degree of slope in each phase. RESULTS. Visual analysis indicated fluctuating edema volume in the first baseline phase, decreasing edema volume in the intervention phase, and increasing edema volume in the second baseline phase. The results did not clearly distinguish between the two bandaging groups. CONCLUSION. Compression bandaging may have benefits in the management of edema after stroke. Further research is required to identify factors contributing to the long-term maintenance of reductions gained after compression bandaging.

What is the evidence for physical therapy poststroke? A systematic review and meta-analysis

BACKGROUND

Physical therapy (PT) is one of the key disciplines in interdisciplinary stroke rehabilitation. The aim of this systematic review was to provide an update of the evidence for stroke rehabilitation interventions in the domain of PT.

METHODS AND FINDINGS

Randomized controlled trials (RCTs) regarding PT in stroke rehabilitation were retrieved through a systematic search. Outcomes were classified according to the ICF. RCTs with a low risk of bias were quantitatively analyzed. Differences between phases poststroke were explored in subgroup analyses. A best evidence synthesis was performed for neurological treatment approaches. The search yielded 467 RCTs (N = 25373; median PEDro score 6 [IQR 5-7]), identifying 53 interventions. No adverse events were reported. Strong evidence was found for significant positive effects of 13 interventions related to gait, 11 interventions related to arm-hand activities, 1 intervention for ADL, and 3 interventions for physical fitness. Summary Effect Sizes (SESs) ranged from 0.17 (95%CI 0.03-0.70; I(2) = 0%) for therapeutic positioning of the paretic arm to 2.47 (95%CI 0.84-4.11; I(2) = 77%) for training of sitting balance. There is strong evidence that a higher dose of practice is better, with SESs ranging from 0.21 (95%CI 0.02-0.39; I(2) = 6%) for motor function of the paretic arm to 0.61 (95%CI 0.41-0.82; I(2) = 41%) for muscle strength of the paretic leg. Subgroup analyses yielded significant differences with respect to timing poststroke for 10 interventions. Neurological treatment approaches to training of body functions and activities showed equal or unfavorable effects when compared to other training interventions. Main limitations of the present review are not using individual patient data for meta-analyses and absence of correction for multiple testing.

CONCLUSIONS

There is strong evidence for PT interventions favoring intensive high repetitive task-oriented and task-specific training in all phases poststroke. Effects are mostly restricted to the actually trained functions and activities. Suggestions for prioritizing PT stroke research are given.

Prevention and treatment of hand oedema after stroke

PURPOSE

As there is no evidence for a specific treatment for post-stroke-induced hand oedema, rehabilitation centre Blixembosch formalized a best practice protocol. We investigated whether the Blixembosch hand oedema protocol is usable in daily practice and leads to lower incidence (prevention) and shorter duration (treatment) compared with care as usual.

METHODS

In a non-randomised comparative trial, we investigated 206 post-stroke patients admitted to two Dutch rehabilitation centres. Hand volumes were measured at least bi-weekly using a volumeter. Treatment was started according the protocol (Blixembosch) or following care as usual (Leijpark). Usability was assessed with a survey among professionals.

RESULTS

In the Blixembosch group, 16% developed oedema after admission, compared with 21% in the control group (p = 0.019). Average duration of oedema (both developed before and after admission) was 6.5 weeks in the Blixembosch group compared with 3.1 weeks in the control group (p = 0.000). Professionals were positive about the protocol.

CONCLUSION

The study showed that the protocol is usable in daily practice and has a small beneficial effect on hand oedema incidence rates compared with care as usual. The negative effect on duration of hand oedema could also be caused by the difference in prognosis between the two groups.

Light Retrograde Massage for the Treatment of Post-Stroke Upper Limb Oedema: Clinical Consensus Using the Delphi Technique

Background:

Oedema of the hemiplegic upper limb is a common complication following stroke and can restrict mobility and function. Limited evidence is available regarding the assessment and treatment of post-stroke upper limb oedema by occupational therapists.

Objective:

To determine consensus amongst occupational therapists with regard to the use of light retrograde massage for the treatment of post-stroke upper limb oedema.

Method:

A Delphi technique was used to gather opinion from a national sample of stroke occupational therapists. Two rounds of questionnaires were undertaken. Data were analysed from the 31 respondents to round two, using the chi-square goodness of fit to determine consensus in relation to statements about the use of light retrograde massage.

Results:

Of the 85 therapists who volunteered for the study, 58 returned round one questionnaires and 56 were eligible to participate. Most of the therapists who responded to round one (41/56, 73%) used light retrograde massage to reduce post-stroke upper limb oedema. Agreement regarding the definition and application of light retrograde massage was identified in round two.

Conclusion:

Despite a lack of evidence for the efficacy of light retrograde massage in stroke patients, this study found that it is often used in clinical practice and that consensus exists about many components of the treatment method. Further research is recommended to investigate the efficacy of light retrograde massage for reducing post-stroke upper limb oedema.

Assessment of oedema in stroke patients: comparison of visual inspection by therapists and volumetric assessment

PURPOSE

To examine the agreement of assessment of hand oedema in stroke patients by clinical judgement and by use of a hand volumeter.

METHOD

A total of 88 rehabilitation patients with stroke received both assessments. Experienced physical therapists classified oedema as 'none', 'minor' or 'severe'. Swelling was independently measured with a hand volumeter. Population data were used to adjust volumeter reading differences for handedness and side of paresis, and to define a cut-off point for oedema of 2 SD of the population distribution.

RESULTS

Based on volumetric assessment, 33% of patients had oedema. Physical therapists classified 50% of patients as having minor or severe oedema. Results of both methods were clearly related, but agreement between the assessments was not more than 'fair' (67% agreement; Kappa 0.34). The level of agreement was not substantially affected by the cut-off point used for the volumeter score, the time between both assessments or by the side of paresis.

CONCLUSION

Agreement between clinical and volumetric assessment of hand oedema in stroke patients is less than desirable. Volumetric assessment of oedema is recommended for research purposes.

Volumetric evaluation of upper extremities in 250 healthy persons

BACKGROUND AND PURPOSE

Upper extremity oedema frequently occurs as a complication of several diseases. The aim of this study was to establish normative data for upper extremity volumes with a modified water displacement method. These data were used to develop predictive formulas helpful in detecting abnormal swelling.

SUBJECTS AND METHODS

Upper extremities of 250 healthy subjects (138 men and 112 women) were measured by water displacement.

RESULTS

A mean difference of 3.0% (3.2%) between right and left arm (forearm) was found. Intra-class correlation coefficients were 0.99 for intra-rater and inter-rater reliabilities. Coefficient of variation was 0.23%. To predict the premorbid volume of an oedematous arm, prediction formulas were constructed.

DISCUSSION AND CONCLUSION

Water displacement as used in this study is a highly reliable technique for volume measurement of upper extremities. This technique was applied to gather normative data for upper extremity volumes. We suggest that this technique can be used in daily clinical practice for the evaluation of upper extremity oedema or atrophy caused by various diseases as well as for volume monitoring. Prediction formulas can be used to define abnormal swelling.

Poststroke hand swelling and oedema: prevalence and relationship with impairment and disability

OBJECTIVE

To examine the prevalence of swelling and oedema of the hand in stroke patients and relationships with impairments and disability.

DESIGN

Cross-sectional.

SETTING

Stroke unit at Rehabilitation Centre De Hoogstraat, The Netherlands.

SUBJECTS

Eighty-eight adult stroke patients who were admitted for clinical rehabilitation during one year (2000).

MEASUREMENTS AND METHODS

Assessment took place two weeks after admission to the rehabilitation centre. Degree of swelling was measured with a hand volumeter and oedema was defined as a volumeter score deviating more than two standard deviations from the expected score derived from population data. Further assessment included tonus (Modified Ashworth Score), sensibility, tactile inattention, carefulness, and motor function (Utrecht Arm/Hand Test). Arm disability was measured with Frenchay Arm Test and Nine-hole Peg Test.

RESULTS

Some degree of hand swelling was present in 72.7% and oedema in 33.0% of our patients. Swelling and oedema were significantly more often seen in patients with hypertonic fingers and impaired sensibility. Patients with hand oedema had significantly worse Frenchay Arm Test and Nine-hole Peg Test scores.

CONCLUSIONS

Swelling and oedema of the hand are common among stroke patients in clinical rehabilitation.

The impact of physical therapy on functional outcomes after stroke: what's the evidence?

OBJECTIVE

To determine the evidence for physical therapy interventions aimed at improving functional outcome after stroke.

METHODS

MEDLINE, CINAHL, Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, DARE, PEDro, EMBASE and DocOnline were searched for controlled studies. Physical therapy was divided into 10 intervention categories, which were analysed separately. If statistical pooling (weighted summary effect sizes) was not possible due to lack of comparability between interventions, patient characteristics and measures of outcome, a best-research synthesis was performed. This best-research synthesis was based on methodological quality (PEDro score).

RESULTS

In total, 151 studies were included in this systematic review; 123 were randomized controlled trials (RCTs) and 28 controlled clinical trials (CCTs). Methodological quality of all RCTs had a median of 5 points on the 10-point PEDro scale (range 2-8 points). Based on high-quality RCTs strong evidence was found in favour of task-oriented exercise training to restore balance and gait, and for strengthening the lower paretic limb. Summary effect sizes (SES) for functional outcomes ranged from 0.13 (95% Cl 0.03-0.23) for effects of high intensity of exercise training to 0.92 (95% Cl 0.54-1.29) for improving symmetry when moving from sitting to standing. Strong evidence was also found for therapies that were focused on functional training of the upper limb such as constraint-induced movement therapy (SES 0.46; 95% Cl 0.07-0.91), treadmill training with or without body weight support, respectively 0.70 (95% Cl 0.29-1.10) and 1.09 (95% Cl 0.56-1.61), aerobics (SES 0.39; 95% Cl 0.05-0.74), external auditory rhythms during gait (SES 0.91; 95% Cl 0.40-1.42) and neuromuscular stimulation for glenohumeral subluxation (SES 1.41; 95% Cl 0.76-2.06). No or insufficient evidence in terms of functional outcome was found for: traditional neurological treatment approaches; exercises for the upper limb; biofeedback; functional and neuromuscular electrical stimulation aimed at improving dexterity or gait performance; orthotics and assistive devices; and physical therapy interventions for reducing hemiplegic shoulder pain and hand oedema.

CONCLUSIONS

This review showed small to large effect sizes for task-oriented exercise training, in particular when applied intensively and early after stroke onset. In almost all high-quality RCTs, effects were mainly restricted to tasks directly trained in the exercise programme.

Quality of the stroke rehabilitation research

The Stroke Rehabilitation Evidence-Based Review revealed a wide range of quality scores across primary studies. The aim of this section is to determine what differences there are across studies and to provide a detailed examination of methodological issues in the stroke rehabilitation literature. Methodology of each article was assessed using the Physiotherapy Evidence Database (PEDro) quality scale. Mean PEDro scores and percentage of studies meeting individual PEDro criteria were determined for all studies, for therapy-based studies only, and for drug-based studies only. It was noted that the stroke rehabilitation literature lacked rigor in the area of concealed allocation, blinding of the assessor, and intention-to-treat analysis. Investigation of the methodological quality of stroke rehabilitation literature emphasizes the need for improved treatment protocols, taking into account previous deficits, during research.

An evidence-based review of stroke rehabilitation

A comprehensive evidence-based review of stroke rehabilitation was created to be an up-to-date review of the current evidence in stroke rehabilitation and to provide specific conclusions based on evidence that could be used to help direct stroke care at the bedside and at home. A literature search using multiple data-bases was used to identify all trials from 1968 to 2001. Methodological quality of the individual randomized controlled trials was assessed using the Physiotherapy Evidence Database (PEDro) quality assessment scale. A five-stage level-of-evidence approach was used to determine the best practice in stroke rehabilitation. Over 403 treatment-based articles investigating of various areas of stroke rehabilitation were identified. This included 272 randomized controlled trials.

Glucocorticoid inhibition of neuropathic limb edema and cutaneous neurogenic extravasation

Sciatic nerve section in rats evokes chronic limb edema, pain behavior, and hindpaw hyperalgesia, a syndrome resembling the complex regional pain syndrome type II (CRPS II or causalgia) in man. Glucocorticoids such as methylprednisolone (MP) have been used as analgesic and anti-edematous agents in patients suffering from CRPS, and interestingly these therapeutic effects appear to persist in some patients after stopping the medication. Similar to the CRPS clinical response to glucocorticoids, we now demonstrate that chronic hindpaw edema in the sciatic transection CRPS model is reversed by a continuous infusion of MP (3 mg/kg/day over 21 days), and this anti-edematous effect persists for at least 1 week after discontinuing MP. Furthermore, there is a chronic increase in spontaneous protein extravasation in the hindpaw skin of rats after sciatic transection, similar to the increased protein extravasation observed in the edematous hands of CRPS patients. A 2-week infusion of MP (3 mg/kg/day) reduced spontaneous protein extravasation in the hindpaw skin by 80%. We postulated that increased spontaneous neurogenic extravasation resulted in development of limb edema in both the animal model and the CRPS patient, and that the anti-edematous effects of MP are due to an inhibition of spontaneous extravasation. Additional experiments examined the inhibitory effects of MP infusion on electrically-evoked neurogenic extravasation in the hindpaw skin of normal rats. MP inhibition was dose- and time-dependent, with an ED(50) of 1.2 mg/kg/day for a 14-day continuous infusion of MP, and a maximum inhibitory effect requiring 17 days of MP infusion (3 mg/kg/day). MP (3 mg/kg/day for 14 days) also blocked both capsaicin- and SP-evoked neurogenic extravasation, indicating a post-junctional inhibitory effect. Our interpretation is that increased spontaneous neurogenic extravasation in this CRPS model contributed to the development and maintenance of hindpaw edema, and that chronic MP administration dose- and time-dependently blocked neurogenic extravasation at a post-junctional level, thus reversing spontaneous extravasation and limb edema in this model.
