Effectiveness of dry needling for upper extremity spasticity, quality of life and function in subacute phase stroke patients

Effects of dry needling on spasticity and motor function in paralympic athletes: a study protocol for a randomised controlled trial

No study has evaluated the effects of dry needling on Paralympic athletes. Therefore, in this study, we will evaluate the effect of dry needling on lower limb spasticity and motor performance, as well as the range of motion of Paralympic athletes. The study will be a triple-blinded, randomised controlled trial. Twenty-four athletes aged 18-45 in T35-T38 groups of the International Paralympic Committee classification will be included in the study. Twelve participants will receive dry needling of the quadriceps and gastrocnemius muscles, and 12 will receive placebo treatment with sham needles at similar points. We will assess the spasticity of the quadriceps and gastrocnemius muscles using the Modified Ashworth Scale, evaluate motor function using the Selective Control Assessment of the Lower Extremity Scale and measure ankle range of motion (ROM) with a goniometer. Considering our hypothesis, the athletes who will undergo the dry needling are supposed to achieve better improvements in spasticity, ROM and motor performance. This study can provide useful information to help better decide on managing complications in Paralympics and its long-term outcomes, to cover the current lack in the literature.

Safety of dry needling in stroke patients: a scoping review

INTRODUCTION

Spasticity is a common problem in stroke patients. Treatments of spasticity often have side effects or are insufficiently effective. Dry needling (DN) has been proposed as a potential additional option to consider in the multimodal treatment of post-stroke spasticity, although questions about its safety remain. The goal of this study is to assess the safety of DN in stroke patients.

EVIDENCE ACQUISITION

A systematic search in Medline, Embase, The Cochrane Library, Web of Science, CIHNAL and PEDro was conducted in June 2023. Two reviewers independently screened abstracts according to the eligibility criteria.

EVIDENCE SYNTHESIS

Twenty-five articles were included in this review. Only six studies reported adverse events, all of which were considered minor. None of the included studies reported any serious adverse events. In four of the included studies anticoagulants were regarded as contra-indicative for DN. Anticoagulants were not mentioned in the other included studies.

CONCLUSIONS

There is a paucity of literature concerning the safety of DN in stroke patients. This review is the first to investigate the safety of DN in stroke patients and based on the results there is insufficient evidence regarding the safety of DN in stroke patients.

CLINICAL REHABILITATION IMPACT

Although DN could be a promising treatment in post-stroke spasticity, further research is indicated to investigate its mechanism of action and its effect on outcome. However, before conducting large clinical trials to assess outcome parameters, the safety of DN in stroke patients must be further investigated.

Effects of neurorehabilitation with and without dry needling technique on muscle thickness, reflex torque, spasticity and functional performance in chronic ischemic stroke patients with spastic upper extremity muscles: a blinded randomized sham-controlled clinical trial

PURPOSE

Evaluation the effects of dry needling on sonographic, biomechanical and functional parameters of spastic upper extremity muscles.

METHODS

Twenty-four patients (35-65 years) with spastic hand were randomly allocated into two equal groups: intervention and sham-controlled groups. The treatment protocol was 12-sessions neurorehabilitation for both groups and 4-sessions dry needling or sham-needling for the intervention group and sham-controlled group respectively on wrist and fingers flexor muscles. The outcomes were muscle thickness, spasticity, upper extremity motor function, hand dexterity and reflex torque which were assessed before, after the 12th session, and after one-month follow-up by a blinded assessor.

RESULTS

The analysis showed that there was a significant reduction in muscle thickness, spasticity and reflex torque and a significant increment in motor function and dexterity in both groups after treatment (p < 0.01). However, these changes were significantly higher in the intervention group (p < 0.01) except for spasticity. Moreover, a significant improvement was seen in all outcomes measured one-month after the end of the treatment in the intervention group (p < 0.01).

CONCLUSIONS

Dry needling plus neurorehabilitation could decrease muscle thickness, spasticity and reflex torque and improve upper-extremity motor performance and dexterity in chronic stroke patients. These changes were lasted one-month after treatment.Trial Registration Number: IRCT20200904048609N1IMPLICATION FOR REHABILITATIONUpper extremity spasticity is one of the stroke consequences which interfere with motor function and dexterity of patient hand in activity of daily livingApplying the dry needling accompanied with neurorehabilitation program in post-stroke patients with muscle spasticity can reduce the muscle thickness, spasticity and reflex torque and improve upper extremity functions.

The Effectiveness of a Single Dry Needling Session on Gait and Quality of Life in Multiple Sclerosis: A Double-Blind Randomized Sham-Controlled Pilot Trial

INTRODUCTION

Gait disorders are a major cause of disability and reduced health-related quality of life in people with multiple sclerosis (pwMS). Dry needling (DN) has demonstrated positive results to improve gait parameters in patients with stroke. The main aim of this study was to evaluate the effect of a single session of DN in the gait performance of pwMS.

METHODS

A double-blind parallel randomized sham-controlled pilot trial was conducted. Study participants received a single session of active DN or sham DN in the gastrocnemius medialis muscle. Pre-treatment and immediately post-treatment measurements were taken, as well as at one and four weeks after the intervention. Outcomes related to gait performance (Timed 25-Foot Walk), self-perceived walking capacity (Multiple Sclerosis Walking Scale), risk of falls (Timed Up and Go test), disability level (Expanded Disability Status Score) and quality of life (Multiple Sclerosis Quality of Life-54 questionnaire and Analogic Quality of Life scale) were evaluated.

RESULTS

18 patients who had multiple sclerosis participated in the study. The group who received active DN showed within-group significant statistical differences immediately after treatment for gait performance (p = 0.008) and risk of falls (p = 0.008), as well as for self-perceived walking capacity at one week (p = 0.017) and four weeks (p = 0.011) and quality of life at four weeks (p = 0.014). Regarding the comparison between groups, only significant results were obtained in the physical domain of the quality of life at four weeks (p = 0.014).

CONCLUSIONS

DN seems to be a promising therapeutic tool for the treatment of gait disorders in pwMS. However, when results were compared with sham DN, no differences were found.

Effects of Dry Needling on Spasticity in Multiple Sclerosis Evaluated Through the Rate-Dependent Depression of the H Reflex: A Case Report

Background

Spasticity is a common symptom of multiple sclerosis (MS) which affects mobility. Dry Needling (DN) has shown a reduction in spasticity in neuromuscular conditions such as stroke and spinal cord injury although the mechanism of action is still unclear. In spastic individuals, the Rate-Dependent Depression (RDD) of the H reflex is decreased as compared to controls and analyzing the effects of DN in the RDD may help to understand its mechanism of action.

Objective

To evaluate the effect of Dry Needling on spasticity measured by the Rate-dependent Depression (RDD) of the H reflex in an MS patient.

Methods

Three time points were evaluated: Pre-intervention (T1), Post-intervention assessments were carried out in the seventh week at two-time points: Before DN (T2) and After DN (T3). Main outcomes included the RDD and latency of the H reflex in the lower limbs at stimulation frequencies of 0.1, 1, 2, and 5 Hz in a five consecutive pulses protocol.

Results

An impairment of the RDD of the H reflex at frequencies ≥1 Hz was found. Statistically significant differences were found when comparing the mean RDD of the H reflex in Pre-intervention compared to Post-intervention at 1, 2, and 5 Hz stimulation frequencies. Mean latencies were statistically lower when comparing Pre- vs Post-intervention.

Conclusion

Results suggest a partial reduction in spasticity represented by decrease of the excitability of the neural elements involved in the RDD of the H reflex following DN. The RDD of the H reflex could be implemented as an objective tool to monitor changes in spasticity in larger DN trials.

Effect of Core Exercises on Motor Function Recovery in Stroke Survivors with Very Severe Motor Impairment

Paresis of the upper and lower limbs is a typical issue in stroke survivors. This study aims to determine whether core exercises help stroke survivors with very severe motor impairment recover their motor function. This study employed a within-subjects design. Eleven hemiparetic stroke patients with very severe motor impairment (FMA score < 35) and ages ranging from 24 to 52 years old were enrolled in this study. All participants engaged in supervised core exercise training twice a week for 12 weeks. The main outcome measures were Fugl-Meyer Assessment Lower Extremity (FMA-LE) and Fugl-Meyer Assessment Upper Extremity (FMA-UE), which were measured before training and at intervals of four weeks during training. Repeated measures ANOVA was used to analyze the effect of core exercises on motor function performance and lower extremity motor function and upper extremity motor function recovery. There were significant differences in the mean scores for motor function performance, lower extremity motor function, and upper extremity motor function throughout the four time points. A post-hoc pairwise comparison using the Bonferroni correction revealed that mean scores significantly increased and were statistically different between the initial assessment and follow-up assessments four, eight, and twelve weeks later. This study suggests that 12 weeks of core exercise training is effective for improving motor function recovery in patients with very severe motor impairment.

Effects of dry needling intervention on lower limb dysfunction after stroke: study protocol for a randomised controlled trial

INTRODUCTION

Lower limb dysfunction is among the common sequelae of patients who had a poststroke and often results in the reduction of the quality of life. This study aims to assess the short and interim-term efficacy of dry needling (DN) intervention on lower extremity function, balance and gait in lower limb dysfunction after stroke.

METHODS AND ANALYSIS

This protocol entails an assessor and statistician-blinded, single-centre study with a randomised controlled trial. Forty-four patients who had a poststroke will be randomly allocated (1:1) to either the conventional treatment group (n=22) or the DN group (n=22). The conventional treatment group will receive conventional rehabilitation treatment once a day for 40 min each time. The treatment will be performed five times a week for 2 weeks. In the DN group, participants will be treated with DN on the basis of the conventional treatment. The intervention will be performed thrice a week for 2 weeks. The primary outcome that determines the efficacy of lower limb dysfunction will be the change in the Fugl-Meyer Assessment of Lower Extremity scale. The secondary indicators include the range of motion of knee and ankle joints, limits of stability, modified Clinical Test of Sensory Interaction on Balance, Timed Up and Go test, Modified Ashworth Scale and Barthel Index. Results will be evaluated at baseline, at 24 hours after intervention, at 2 weeks after intervention and at 3-month follow-up. Data will be released after the completion of the study. Adverse events will be reported.

ETHICS AND DISSEMINATION

The experiment was approved by the Ethical Committee of Shanghai Tong Ren Hospital in October 2021 (approval number: 202105702). The results of this study will be published in peer-reviewed journals.

Effects of dry needling and exercise therapy on post-stroke spasticity and motor function- protocol of randomized clinical trial

BACKGROUND

Spasticity is one of the most common problems after the first stroke. Dry needling (DN) has been presented as a new therapeutic approach used by physiotherapists for the management of post-stroke spasticity. This study aimed to determine whether the addition of exercise therapy to the DN results in better outcomes in wrist flexors spasticity, motor neuron excitability, motor function and range of motion (ROM) in patients with chronic stroke.

METHODS

We will use a single-blind randomized controlled trial (RCT) in accordance with the CONSORT guidelines. A total of 24 patients with stroke will be included from the University Rehabilitation Clinics. The outcome measures will include Modified Modified Ashworth Scale, H_max/M_max ratio, H-reflex latency, Action Research Arm Test, Fugl-Meyer Assessment, and wrist extension active and passive range of motion. Patients in the DN and exercise therapy group will undergo 4 sessions of deep DN in flexor carpi radialis and flexor carpi ulnaris muscles on the affected upper limb and exercise therapy. Participants in the DN group will only receive DN for target muscles. Clinical and neurophysiological tests will be performed at baseline, after four therapy sessions, and at three weeks' follow-up.

DISCUSSION

This study will provide evidence for additional effects of exercise therapy to DN in comparison to DN alone on wrist flexors spasticity, motor neuron excitability, upper-limb motor function, and ROM in patients with chronic stroke.

Effects of Functional Acupuncture on Upper Limb Spasticity After Ischemic Stroke: A Protocol for a Randomized Controlled Parallel Clinical Trial

Background

Upper limb spasticity (ULS) is a common complication after stroke, which seriously affects the quality of life and rehabilitation of patients. There are different treatment methods for post-stroke spasticity (PSS). Our group found that functional acupuncture (FA) can effectively improve forearm spasticity and hand dysfunction after stroke, but the efficacy of ULS needs to be further verified. Therefore, this subject has mainly used clinical randomized controlled trials to evaluate the clinical efficacy of FA in the treatment of ULS after ischemic stroke.

Method

This is a parallel design and randomized controlled trial. We selected 108 patients who met the predefined criteria and randomized them into two groups, the experimental group and the control group. The experimental group receives FA and routine rehabilitation treatment. The control group received traditional acupuncture (TA) and routine rehabilitation treatment. All patients received 20 courses of treatment for 4 weeks, and the modified Ashworth score (MAS), clinical neurological deficit score (CSS), Fugl-Meyer upper extremity function assessment (FMA-UE), and the Modified Barthel Index (MBI) scores were evaluated before and after treatment.

Discussion

This trial is mainly to study the clinical efficacy of FA in the treatment of ULS after ischemic stroke. It will not only provide a new idea for the clinical treatment of upper limb post-stroke spasticity (ULPSS) but also will provide effective experimental support and a theoretical basis for the clinic.

Dry Needling and Antithrombotic Drugs

Many clinicians increasingly use dry needling in clinical practice. However, whether patients' intake of antithrombotic drugs should be considered as a contraindication for dry needling has not been investigated to date. As far as we know, there are no publications in analyzing the intake of antiplatelet or anticoagulant agents in the context of dry needling techniques. A thorough analysis of existing medications and how they may impact various needling approaches may contribute to improved evidence-informed clinical practice. The primary purpose of this paper is to review the current knowledge of antithrombotic therapy in the context of dry needling. In addition, reviewing guidelines of other needling approaches, such as electromyography, acupuncture, botulinum toxin infiltration, and neck ultrasound-guided fine-needle aspiration biopsy, may provide specific insights relevant for dry needling. Based on published data, taking antithrombotic medication should not be considered an absolute contraindication for dry needling techniques. As long as specific dry needling and individual risks are properly considered, it does not change the risk and safety profile of dry needling. Under specific circumstances, the use of ultrasound guidance is recommended when available.

Cost-Effectiveness of Upper Extremity Dry Needling in Chronic Stroke

Introduction: Dry needling is a non-pharmacological approach that has proven to be effective in different neurological conditions. Objective: The aim of this study was to evaluate the cost-effectiveness of a single dry needling session in patients with chronic stroke. Methods: A cost-effectiveness analysis was performed based on a randomized controlled clinical trial. The results obtained from the values of the EuroQol-5D questionnaire and the Modified Modified Ashworth Scale were processed in order to obtain the percentage of treatment responders and the quality-adjusted life years (QALYs) for each alternative. The cost analysis was that of the hospital, clinic, or health center, including the equipment and physiotherapist. The cost per respondent and the incremental cost-effectiveness ratio of each alternative were assessed. Results: Twenty-three patients with stroke were selected. The cost of DN treatment was EUR 14.96, and the data analysis showed a favorable cost-effectiveness ratio of both EUR/QALY and EUR/responder for IG, although the sensitivity analysis using limit values did not confirm the dominance (higher effectiveness with less cost) of the dry needling over the sham dry needling. Conclusions: Dry needling is an affordable alternative with good results in the cost-effectiveness analysis—both immediately, and after two weeks of treatment—compared to sham dry needling in persons with chronic stroke.

Effects of dry needling on function, hypertonia and quality of life in chronic stroke: a randomized clinical trial

BACKGROUND

Persons with stroke commonly have impairments associated with a reduction in functionality. Motor impairments are the most prevalent, causing an impact on activities of daily life.

OBJECTIVE

The aim of this study was to evaluate the effect of a session of dry needling (DN) applied to the upper extremity muscles on the sensorimotor function, hypertonia, and quality of life of persons with chronic stroke.

METHODS

A randomized, sham-controlled clinical trial was performed. Participants were randomly assigned into an intervention group that received a single session DN in the biceps brachii, brachialis, flexor digitorum superficialis and profundus, extensor digitorum, adductor pollicis and triceps brachii muscles, or into a control group that received the same treatment but with a sham DN intervention. Treatment outcomes included the Fugl-Meyer Assessment Scale for the upper extremity, the Modified Modified Ashworth Scale, and the EuroQol-5D questionnaire. Measurements were carried out before, immediately after, and 14 days after intervention.

RESULTS

Twenty-three persons participated in the study. Significant differences between groups were observed after the intervention in the total wrist-hand motor score (p = 0.023) and sensorimotor score (p = 0.022), for hypertonia in the elbow extensors both after treatment (p = 0.002) and at follow-up (p = 0.018), and in quality of life at follow-up (p = 0.030).

CONCLUSIONS

A single session of DN improved total wrist-hand motor function and total sensorimotor function in persons with chronic stroke immediately after treatment, as well as quality of life 2 weeks after treatment.

Cost-effectiveness of upper extremity dry needling in the rehabilitation of patients with stroke

INTRODUCTION

Dry needling (DN) has been shown to be effective for the treatment of upper extremity hypertonia in patients with stroke.

PURPOSE

To evaluate the cost-effectiveness of DN in patients with stroke.

METHODS

A cost-effectiveness analysis was performed in a research study conducted at a Spanish public hospital where patients were classified into two groups with or without DN. Hypertonia was measured using the Modified Modified Ashworth Scale (MMAS), and quality of life (QOL) was assessed using the EuroQoL 5-dimension questionnaire. Data regarding the effects and costs of physiotherapy were presented by calculating the mean and 95% confidence interval. The health outcomes were evaluated considering the rate of responders to the treatment based on the MMAS. Spanish preference weights were used to estimate quality-adjusted life years (QALYs). The incremental cost-effectiveness ratio (ICER) and incremental cost-utility ratio (ICUR) were calculated to determine the economic value of DN.

RESULTS

Eighty patients with stroke in the subacute stage of recovery were selected to participate in this study. Based on the rate of responders, the ICER of the DN group was very low. Despite the sensitivity analysis performed, the results of the ICUR were not encouraging.

DISCUSSION

Cost-effectiveness with responder rate results were favourable for the DN group and were confirmed by the sensitivity analysis according to levels of care. In addition, our findings revealed that 4 weeks of treatment could be more cost-effective than 8 weeks. DN treatment of the upper extremity appears to be cost-effective based on the rate of responders measured using the MMAS scale.

Immediate Effect of Dry Needling at Myofascial Trigger Point on Hand Spasticity in Chronic Post-stroke Patients: A Multicenter Randomized Controlled Trial

Background: Hand spasticity after stroke influences the rehabilitation of hand function. Immediate and effective relief of spasticity potentially creates conditions for later rehabilitation training, which has far-reaching significance in the smooth transition of patients to the recovery period.

Objective: To evaluate the immediate effect of dry needling (DN) at myofascial trigger point on hand spasticity in stroke patients.

Methods: This was a prospective, evaluator blind, multicenter, randomized controlled study. A total of 210 participants were randomly divided into DN group (DN, N = 70), sham dry needling group (SDN, N = 70), and control group (N = 70). Participants in the DN group were treated with DN at myofascial trigger point five times (30 min each time) every week for 4 weeks. Subjects in the SDN group were manipulated the same way as in the DN group, except that the acupuncture site was located in the area adjacent to the myofascial trigger point, which constituted a SDN. Routine rehabilitation treatment was performed for participants in the two groups and in the control group. The primary evaluation index was the immediate effect of hand spasticity relief. Secondary evaluation indicators included the cumulative effect of hand spasticity relief from baseline to week 4, and the changes in flexion angles of the wrist, thumb, and fingers 2–5 in the rest position before, immediately after, and 4 weeks after intervention.

Results: The immediate effective rate of spasticity relief (thumb, fingers 2–5, and wrist) of patients with different degrees of spasticity in the DN group was higher than that in the control and SDN groups (thumb, χ² = 55.833, P < 0.001; fingers 2–5, χ² = 68.096, P < 0.001; wrist, χ² = 49.180, P < 0.001) (P < 0.05). The effective rate of spasticity relief from baseline to 4 weeks in the DN group exceeded that in the control group and SDN groups (thumb, χ² = 8.806, P = 0.012; fingers 2–5, χ² = 8.087, P = 0.018; and wrist, χ² = 8.653, P = 0.013) (P < 0.05). No difference in immediate and cumulative effect was found between the control group and SDN group. The change of joints flexion angles in resting position before and after each treatment in the DN group was higher than that in the control and SDN groups (P < 0.05), but it was not significantly different between the control group and SDN group. At 4 weeks, although the change in the DN group was higher than that in the control group and SDN group, this difference was not statistically significant (P > 0.05).

Conclusion: Dry needling can relieve varying degrees of hand spasticity instantly in post-stroke.

Effects of Deep Dry Needling on Tremor Severity and Functionality in Stroke: A Case Report

This study aimed to determine the effect of one session of dry needling on the severity of tremor, motor function and skills, and quality of life of a 39-year-old woman with post-stroke tremor. Myofascial trigger points (MTrP) of the following muscles were treated: extensor digitorum, flexor digitorum superficialis and profundus, brachioradialis, short head of biceps brachii, long head of triceps brachii, mid deltoid, infraspinatus, teres minor, upper trapezius, and supraspinatus. Outcomes were assessed via (i) clinical scales (activity of daily living (ADL-T24), a visual analog scale (VAS), and the Archimedes spiral), (ii) a functional test (9-Hole Peg test), and (iii) biomechanical and neurophysiological measurements (inertial sensors, electromyography (EMG), and dynamometry). The subject showed a decrease in the severity of tremor during postural (72.7%) and functional (54%) tasks after treatment. EMG activity decreased after the session and returned to basal levels 4 days after. There was an improvement post-intervention (27.84 s) and 4 days after (32.43 s) in functionality and manual dexterity of the affected limb, measured with the 9-Hole Peg test, as well as in the patient's hand and lateral pinch strength after the treatment (26.9% and 5%, respectively), that was maintained 4 days later (15.4% and 16.7%, respectively).
