Effectiveness of Extracorporeal Shock Wave Therapy in Treatment of Spasticity of Different Aetiologies: A Systematic Review and Meta-Analysis. J Clin Med 2024; 13:1323. [PMID: 38592705 PMCID: PMC10932441 DOI: 10.3390/jcm13051323] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/13/2023] [Revised: 02/19/2024] [Accepted: 02/22/2024] [Indexed: 04/10/2024] Open
Abstract
Background: Spasticity is a motor disorder characterised by exaggerated movements of the tendons and accompanied by hyperreflexia and hypertonia. Extracorporeal shock wave therapy (ESWT) is used as a treatment for spasticity, although more evidence is needed on the effectiveness of this therapy in the treatment of spasticity. Therefore, the aim of this study was to assess the effectiveness ESWT in the treatment of upper and lower limbs spasticity in both children and adults through different aetiologies. Methods: A systematic search was performed in different databases from inception to December 2023. Random-effects meta-analysis was used to estimate the efficacy of ESWT on spasticity using the Modified Ashworth Scale. Results: Sixteen studies were included in the systematic review and meta-analysis. The effect of ESWT on spasticity measured with the Modified Ashworth Scale shows a significant decrease in spasticity in the upper limbs and in the lower limbs in adults with chronic stroke and in children with cerebral palsy, is more effective immediately after application, and maintains its effect up to 12 weeks post treatment. Conclusions: These findings are important for clinical practice since they show evidence that ESWT is effective in reducing spasticity in both children and adults.

Examining the role of intrinsic and reflexive contributions to ankle joint hyper-resistance treated with botulinum toxin-A. J Neuroeng Rehabil 2023; 20:19. [PMID: 36750869 PMCID: PMC9906865 DOI: 10.1186/s12984-023-01141-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/24/2022] [Accepted: 01/18/2023] [Indexed: 02/09/2023] Open
Abstract
BACKGROUND Spasticity, i.e. stretch hyperreflexia, increases joint resistance similar to symptoms like hypertonia and contractures. Botulinum neurotoxin-A (BoNT-A) injections are a widely used intervention to reduce spasticity. BoNT-A effects on spasticity are poorly understood, because clinical measures, e.g. modified Ashworth scale (MAS), cannot differentiate between the symptoms affecting joint resistance. This paper distinguishes the contributions of the reflexive and intrinsic pathways to ankle joint hyper-resistance for participants treated with BoNT-A injections. We hypothesized that the overall joint resistance and reflexive contribution decrease 6 weeks after injection, while returning close to baseline after 12 weeks. METHODS Nine participants with spasticity after spinal cord injury or after stroke were evaluated across three sessions: 0, 6 and 12 weeks after BoNT-A injection in the calf muscles. Evaluation included clinical measures (MAS, Tardieu Scale) and motorized instrumented assessment using the instrumented spasticity test (SPAT) and parallel-cascade (PC) system identification. Assessments included measures for: (1) overall resistance from MAS and fast velocity SPAT; (2) reflexive resistance contribution from Tardieu Scale, difference between fast and slow velocity SPAT and PC reflexive gain; and (3) intrinsic resistance contribution from slow velocity SPAT and PC intrinsic stiffness/damping. RESULTS Individually, the hypothesized BoNT-A effect, the combination of a reduced resistance (week 6) and return towards baseline (week 12), was observed in the MAS (5 participants), fast velocity SPAT (2 participants), Tardieu Scale (2 participants), SPAT (1 participant) and reflexive gain (4 participants). On group-level, the hypothesis was only confirmed for the MAS, which showed a significant resistance reduction at week 6. All instrumented measures were strongly correlated when quantifying the same resistance contribution. CONCLUSION At group-level, the expected joint resistance reduction due to BoNT-A injections was only observed in the MAS (overall resistance). This observed reduction could not be attributed to an unambiguous group-level reduction of the reflexive resistance contribution, as no instrumented measure confirmed the hypothesis. Validity of the instrumented measures was supported through a strong association between different assessment methods. Therefore, further quantification of the individual contributions to joint resistance changes using instrumented measures across a large sample size are essential to understand the heterogeneous response to BoNT-A injections.

Abstract
Spinal cord injury (SCI) affects an estimated three million persons worldwide, with ∼180,000 new cases reported each year leading to severe motor and sensory functional impairments that affect personal and social behaviors. To date, no effective treatment has been made available to promote neurological recovery after SCI. Deficits in motor function is the most visible consequence of SCI; however, other secondary complications produce a significant impact on the welfare of patients with SCI. Spasticity is a neurological impairment that affects the control of muscle tone as a consequence of an insult, trauma, or injury to the central nervous system, such as SCI. The management of spasticity can be achieved through the combination of both nonpharmacological and pharmacological approaches. Baclofen is the most effective drug for spasticity treatment, and it can be administered both orally and intrathecally, depending on spasticity location and severity. Interestingly, recent data are revealing that baclofen can also play a role in neuroprotection after SCI. This new function of baclofen in the SCI scope is promising for the prospect of developing new pharmacological strategies to promote functional recovery in patients with SCI.

Abstract
Hand spasticity with a flexor pattern is a common problem affecting stroke patients and can result in pain, contractures, esthetic concerns, skin maceration, and overall loss of function. Poststroke (≥6 months) hemiparetic adult patients having a Modified Ashworth Scale (MAS) score of ≥1 for metacarpophalangeal flexion and thumb adduction spasticity were selected to receive an ultrasound-guided 20% ethyl alcohol block performed perineurally at the level of the deep branch of the ulnar nerve. Their MAS scores were evaluated pretreatment at 1 month and the change in MAS scores was assessed using Wilcoxon’s test. The threshold for statistical significance was set at p < 0.05. The mean MAS score for the flexor muscles of the 5 MCP joints and for thumb adduction was reduced from 3.3 ± 0.5 at pretreatment to 0.9 ± 0.5 at 1 month after the injection for the 10 patients. One month after the injection, the MAS scores were significantly reduced compared with those at pretreatment (p < 0.001), without complications. These are encouraging results showing that ultrasound-guided alcohol blocks of the deep branch of the ulnar nerve are safe and can help chronic stroke patients with metacarpophalangeal flexion and thumb adduction spasticity at 1 month.

Abstract
Intrathecal baclofen therapy, given via an implanted pump in the abdominal wall either as a continuous infusion or bolus dosing, has been used for more than 25 years to treat the spasticity and dystonia associated with various brain and spinal cord conditions. Pediatric clinicians occasionally encounter baclofen pumps, and in the pediatric setting, significant morbidity can arise from their use. This article presents the background, mechanism of action, uses, and complications of intrathecal baclofen therapy and discusses various management strategies should complications occur.

OBJECTIVES A systematic review and meta-analysis using the Grades of Recommendation, Assessment, Development and Evaluation (GRADE) approach; evaluating Botulinum Toxin type A efficacy on improving ease of care in the upper/lower limb. DATA SOURCES Pubmed, Cinahl, Amed, Embase and Cochrane databases. English Language. Search to July 2014. REVIEW METHODS All randomized, placebo controlled trials on adults with difficulty in caring for the upper/lower limb resulting from spasticity of any origin and treated with a single dose of Botulinum Toxin A. Evidence quality was assessed by GRADE. RESULTS A total of 32 studies were reviewed. Meta-analysis was carried out on 11 upper limb and three lower limb studies. Evidence quality for the upper limb was moderate. A significant result for Botulinum Toxin A was found at four to 12 weeks for the upper limb (SMD 0.80, CI 0.55, 1.06, p < 0.0001). The effects were maintained for up to six months (SMD 0.48, CI 0.34, 0.62, p < 0.0001). Evidence quality was very low for the lower limb. Meta-analysis was only possible for global assessment of benefit. No significant effect was found. ( PATIENT RR 1.37 CI (0.94, 2.00) p = 0.11; clinician: RR 1.06 (0.84, 1.34) p = 0.60.) CONCLUSION Botulinum Toxin A improves ease of care in the upper limb for up to six months. No conclusion can be drawn for the lower limb.

Abstract
Stroke is a major public health concern, with estimated 16 million people worldwide experiencing first-time strokes each year, a number that is expected to rise. Two-thirds of those experiencing a stroke are younger than 70 years of age. Stroke is a leading cause of disability in adults as a result of major sequelae that include spasticity, cognitive impairment, paresis, and depression. Disabling spasticity, defined as spasticity severe enough to require intervention, occurs in 4% of stroke survivors within 1 year of first-time stroke. The aim of this report is to focus instead on a discussion of patient-provider communication, and its role in post-stroke spasticity (PSS) rehabilitation within the context of patient-centered health care. A discussion based on a review of the literature, mainly since 2000. Problems within communication are identified and suggestion to enhance communication are proposed thus improving patient-centered goal setting/goal achievement for the effective management of spasticity rehabilitation. These are as follows: (i) involving family members, (ii) educating patients and family members on stroke and rehabilitation, and (iii) establishing a common definition for long-term goals. Increased communication among physicians, patients, and payers may bridge some of the gaps and increase the effectiveness of PSS rehabilitation and management.

Abstract
Objectives: A systematic review and meta-analysis using the Grades of Recommendation, Assessment, Development and Evaluation (GRADE) approach to evaluate Botulinum Toxin Type A efficacy on spasticity and pain in the upper/lower limb in adults. Data Sources: Pubmed, Cinahl, Amed, Embase and Cochrane Databases. English language. 1989 to April 2013. Review methods: All randomized controlled trials on adults with spasticity of any origin in the upper or lower limb, treated with a single dose of Botulinum Toxin A, with outcome measures for pain or spasticity. Quality was assessed by GRADE, which uses a transparent, structured process for developing and presenting summaries of evidence, including its quality, for systematic reviews. Results: A total of 37 studies were reviewed. A meta-analysis was carried out on 10 for pain and 21 for spasticity. Evidence quality was low/very low for pain. No significant effect was found in the upper limb (standardised mean difference (SMD) = 0.44, confidence interval (CI) –0.02 to 0.90, Z = 1.88, P=0.06), and no effect was found in the lower limb (risk ratio (RR) = 1.01 CI 0.19 to 5.36, Z = 0.02, P=0.99). Evidence quality for spasticity was moderate. Significant effects were found for Botulinum Toxin in the upper limb (weighted mean difference (WMD) = 0.88, CI 0.63 to 1.14, Z = 6.86, P<0.00001), and the lower limb (RR=2.42, CI 1.60 to 3.65, Z=4.18, P<0.0001). Conclusion: The use of Botulinum Toxin A is supported for upper and lower limb spasticity. Further evidence is needed for spasticity-related pain. Evidence quality is reduced by inadequate study design.

Abstract
BACKGROUND Recently, the European Journal of Neurology published international consensus statements for the assessment, treatment and aftercare associated with the use of botulinum neurotoxin type A. This survey examined current allied health practice in relation to botulinum neurotoxin type A use in Australia in the light of these guidelines. METHODS An electronic questionnaire was distributed to members of neurology groups of the Australian Physiotherapy Association and Occupational Therapy Australia. The questionnaire explored assessment processes used, familiarity with pharmaceutical benefits scheme indications for botulinum neurotoxin type A use, goal setting and outcome measurement, follow-up therapy and access to spasticity management services. RESULTS The 123 survey respondents (81 from the Australian Physiotherapy Association - response rate 16.2%, 42 from Occupational Therapy Australia - response rate 6.4%) reported that focal spasticity was a major problem for which botulinum neurotoxin type A was a primary intervention. The Tardieu scale was more frequently used than the modified Ashworth scale (82% vs. 48%). Most therapists (76.3%) reported being confident diagnosing spasticity and its functional implications (84.2%), but fewer were confident discussing referral for botulinum neurotoxin type A with doctors (56.1%). Goals were set in conjunction with the client (93.6%). Barriers to injection and adjunctive therapy (motor training etc.) included waiting times for botulinum neurotoxin type A injection, access to specialist adjunctive therapists and referral for treatment. CONCLUSIONS Allied health practitioners in Australia report clinical practice to be closely aligned with international guidelines for the use of botulinum neurotoxin type A in adult spasticity. Therapist confidence in advocating for botulinum neurotoxin type A injection, consistent use of objective measures of spasticity and treatment outcomes and barriers to providing adjunctive therapy need to be addressed.

Abstract
Spasticity is a velocity-dependent increase in muscle tone and uncontrolled, repetitive, involuntary contractions of skeletal muscles. Spasticity presents as upper motor neuron symptoms in patients with central nervous system pathology such as stroke, spinal cord injury, brain injury, or multiple sclerosis. As a result, a patient can have significant pain and limited mobility, which can lead to decreased quality of life and difficulty maintaining personal care. In this article we discuss mechanisms, indications, efficacy, and side effects of the most accepted current treatments. Currently available treatment options include oral medications and interventional procedures. Oral medications comprise centrally acting agents, such as baclofen, clonidine, and tizanidine, as well as anticonvulsants such as benzodiazepines and gabapentin and peripherally acting dantrolene. Interventional procedures include focal injections of botulinum toxin, phenol or alcohol, and an intrathecal baclofen pump. Surgical treatments include selective dorsal rhizotomy and neurectomy. We found that there are several treatments available with data to support their use, but many still need further research to prove their efficacy and develop optimal utilization.

Abstract
OBJECTIVES To quantify tendon tap response (TTR) properties and their position dependence using multiple neuromechanical parameters, and to analyze correlations among neuromechanical and clinical measures. DESIGN Hyperexcitable dynamics of TTR were investigated in a case-control manner. An instrumented hammer was used to induce the patellar deep tendon reflex (DTR), with reflex-mediated electromyography and torque responses measured across a range of knee flexion. SETTING Research laboratory in a rehabilitation hospital. PARTICIPANTS Chronic hemiplegic stroke survivors (n=9) and healthy subjects (n=13). INTERVENTIONS Not applicable. MAIN OUTCOME MEASURES Neuromechanical measures (system gain, contraction rate, half-relaxation rate, reflex loop delay, peak reflex torque, peak reflex electromyography, and reflex threshold in tapping force) were measured to characterize neuromuscular properties of patellar TTR. Clinical measurements were taken using the DTR scale and the Modified Ashworth Scale. RESULTS The system gain, contraction rate, half-relaxation rate, and peak reflex-mediated torque in the stroke group were generally higher, whereas the reflex threshold in the stroke group was significantly lower than their counterparts in the control group across 45° to 90° of knee flexion (P<.05). The 4 parameters were significantly higher at 60° and 75° of flexion than at 15°, 30°, 45°, and 90°, and their correlations with the 2 clinical scales at 60°, 75°, and 90° of flexion were also significantly higher than those at 15°, 30°, and 45° (P<.05). CONCLUSIONS The results showed hyperexcitability of TTR in stroke, quantified using a number of neuromechanical measures. Those measures peak around 60° to 75° of knee flexion and were correlated with clinical scales.

Abstract
BACKGROUND AND PURPOSE Poststroke spasticity often negatively affects functional activities and daily living and frequently is accompanied by pain, abnormal limb postures, and contractures. The purpose of this case report is to describe the long-term benefit of botulinum toxin A in a patient with poststroke spasticity. CASE DESCRIPTION A 35-year-old woman with poststroke upper-limb spasticity who had lost function in her left hand was treated with onabotulinumtoxinA and physical therapy. Over 25 months, the patient received a physical therapy and occupational therapy program and received onabotulinumtoxinA injections into muscles of the left hand and arm, significantly reducing tone and facilitating recovery of function. Practical assessments, the Ashworth Scale, and electrophysiology were used to measure changes over time. No functional scales or dexterity scales were used to measure changes. OUTCOMES OnabotulinumtoxinA injections were discontinued when treatment goals were attained, and no further improvements were achieved. After more than 2½ years without further onabotulinumtoxinA treatments, the patient maintained range of motion and some functional use and dexterity in her left hand. DISCUSSION This case report illustrates the efficacy and long-term benefit of onabotulinumtoxinA, combined with physical therapy and occupational therapy, in the successful treatment of poststroke spasticity.

Abstract
Spasticity is a sign of upper motor neurone lesion, which can be located in the cerebrum or the spinal cord, and be caused by stroke, multiple sclerosis, spinal cord injury, brain injury, cerebral paresis, or other neurological conditions. Management is dependent on clinical assessment. Positive and negative effects of spasticity should be considered. Ashworth score and the modified Ashworth score are the most used scales for assessment of spasticity. These and other spasticity scales are based on assessment of resistance during passive movement. The main goal of management is functional improvement. A novel 100-point score to assess disability, function related to spasticity (Rekand disability and spasticity score) is proposed. Management of spasticity should be multimodal and should always include physiotherapy or exercise. Oral medications such as baclofen and tizanidine have limited efficacy and considerable side effects, but are easiest to use. Botulinum toxin combined with physiotherapy and/or orthopaedic surgery is effective treatment of localized spasticity. Treatment with intrathecal baclofen via programmable implanted pump is effective in generalized spasticity, particularly in the lower extremities. Neurosurgical and orthopaedic procedures may be considered in intractable cases.

Abstract
AIM The aim of the study was to explore the timing of effects of intrathecal baclofen therapy in children with cerebral palsy. METHODS Thirty five children with severe disabilities with cerebral palsy who started continuous intrathecal baclofen therapy (CITB) were followed for 18 months. Pain, number of awakenings during night, spasticity, GMFM-66 scores and PEDI scores were recorded the day before pump implantation and after 6 and 18 months of treatment respectively. RESULTS Introduction of CITB was associated with changes across all ICF dimensions. Reduced pain and improved sleep occurred within 6 months of treatment. Social function improved within 6 months and continued to improve until 18 months of CITB. Mobility also improved, but with a latency. CONCLUSION There seems to be a sequence of changes after introduction of continuous intrathecal baclofen in a child with cerebral palsy that may guide the multidisciplinary team in their timing of therapy during post-surgical follow-up.
