FES cycling reduces spastic muscle tone in a patient with multiple sclerosis

We report on a multiple sclerosis patient who received functional electrical stimulation to reduce spastic muscle tone of the lower limbs. Stimulation by means of surface electrodes applied to the thigh muscles induced cycling leg movements. Spastic muscle tone was measured clinically using the modified Ashworth scale and semiautomatically by pendulum testing of spasticity. This was done before and directly after stimulation. The patient was able to endure the stimulation for ca. 30 minutes; there was a significant reduction of spasticity after each stimulation session. We conclude, that this type of stimulation could be another potential treatment modality for multiple sclerosis patients, especially those with a high score in the expanded disability Status scale.

The effect of Bobath approach on the excitability of the spinal alpha motor neurones in stroke patients with muscle spasticity

A clinical study was performed to evaluate the efficacy of the Bobath approach on the excitability of the spinal alpha motor neurones in patients with poststroke spasticity. Ten subjects ranging in age from 37 through 76 years (average 60 years) with ankle plantarflexor spasticity secondary to a stroke were recruited and completed the trial. They had physiotherapy according to Bobath concept for ten treatment sessions, three days per week. Two repeated measures, one before and another after treatment, were taken to quantify clinical efficacy. The effect of this type of therapy on the excitability of alpha motor neurones (aMN) was assessed by measuring the latency of the Hoffmann reflex (H-reflex) and the Hmax/Mmax ratio. The original Ashworth scale and ankle range of motion were also measured. The mean HmaxlMmax ratio on the affected side at baseline was high in the study patients. However, there were no statistically significant differences in the HmaxlMmax ratio or in the H-reflex latency between the baseline values and those recorded after therapy intervention. Before treatment, the HmaxlMmax ratio was significantly higher in the affected side than in the unaffected side. However, it was similar at both sides after treatment. Following treatment, the significant reduction in spasticity was clinically detected as measured with the original Ashworth scale. The ankle joint active and passive range of motion was significantly increased. In conclusion, Bobath therapy had a statistically significant effect on the excitability of the aMN in the affected side compared to the unaffected side in stroke patients with muscle spasticity.

[The parents expectations after baclofen pump implantation in child with severe spasticity in physical rehabilitation and psychological aspects]

Treatment of spasticity with intrathecal baclofen pump implantation is a chance for clinical improvement in patients with severe spasticity. It results also in improvement of patients and their families quality of life. The aim of study was to assess the effects after baclofen pump implantation due to parents expectations.

MATERIAL AND METHODS

The study was performed on a group of 17 parents which children have implantable baclofen pump. According to Assessment of Efficacy in Treatment Spasticity Questionaire was determined if the effects after pump implantation are satisfactory in parents opinion. There were done compartments of results from Questionaire, for which we can say about 1. good effects, 2. satisfactory effects, and 3. unsatifactory effects.

RESULTS

In a group of 17 parents of children with implanted baclofen pump 10 assess that the effects after pump implantation are good, 5--effects are satisfactory and 2--effects are unsatisfactory. Parents noted substantial improvement in sleep and rest, in facilitating of body care, in reducing the pain and simplifies followed rehabilitation. Partial dissatifaction comed from excessive expectations due to terapeutical possibilities of the implantable baclofen pump.

CONCLUSION

Intrathecal baclofen therapy brings essential benefits to patients and their families.

[Psychological aspects of intrathecal baclofen pump implantation in children]

The issues presented concern the difficulties facing a family with a spastic child. The aim of the thesis was to define the role of a psychologist in solving difficulties reported by parents of children with spasticity being treated with the help of intrathecal baclofen pump implantation. The research was done using the method of partially structured interviews with the parents of patients after the implantation of the baclofen pump as well as the results of a Questionnaire estimating the effects of treating spastics. The results show that the two main categories of difficulties reported by the parents concern the medical and nurse care, information and communication problems as well as physical and psychological exhaustion. The role and usability of a psychologist in the process of supporting families of spastic children treated with the baclofen pump has been described from a systematic perspective. A psychologist has been indicated as an advantageous support offering benefits to all--the patients, their families as well as the medical personnel--during the whole treatment process.

Hybrid Power-Assisted Functional Electrical Stimulation to Improve Hemiparetic Upper-Extremity Function

OBJECTIVE

The effect on spastic hemiparesis of a hybrid therapy consisting of functional electrical stimulation and block therapy was examined.

DESIGN

Sixteen consecutively enrolled stroke patients who had spastic upper-extremity impairments more than 1 yr after stroke were recruited for this nonblinded randomized controlled trial. Patients underwent hybrid functional electrical stimulation therapy on their extensor carpi radialis longus and brevis, extensor digitorum communis, and extensor indicis proprius muscles once or twice a week for 4 mos after motor point blocks at the spastic finger flexor muscles. Surface electrodes picked up the electromyography signal and stimulated those muscles in proportion to the integrated electromyography signal obtained by the functional electrical stimulation device. The root mean square of the extensor carpi radialis longus and extensor digitorum communis maximum voluntary electromyography, active range of motion of wrist extension, finger extension, Modified Ashworth Scale, and two clinical tests were examined before and after training.

RESULTS

Root mean square, active range of motion, Modified Ashworth Scale, and two clinical tests showed marked improvement in all patients as compared with the control subjects.

CONCLUSIONS

The hybrid therapy was effective for patients with chronic spastic hemiparesis. Proprioceptional sensory feedback may have an important role in power-assisted functional electrical stimulation therapy.

Evaluation of a multimodal management of prematurity-related spasticity

To examine the efficacy of a rehabilitation protocol, focusing on spasticity management through botulinum toxin A injections in the lower limbs, an etiologically homogeneous group of 57 prematurely born children with cerebral palsy was prospectively evaluated (minimum follow-up 18 months) under pragmatic conditions. Gross Motor Function Classification System categories were: I = 12, II = 9, III = 16, IV = 15, V = 4. Outcome was evaluated with goniometry, Gross Motor Function Measure, functional goal attainment at baseline and in subsequent months, the Gross Motor Function Classification System, functional mobility status, and parents' satisfaction at more than 18 months after first botulinum toxin. Goniometry demonstrated significantly improved range of movement in lower limbs at 10 days and 1 month after botulinum toxin. Differences persisted >18 months at the popliteal angles (P < 0.001). Gross Motor Function Measure changed significantly in 20 children (8 points in total score) at 3 months after first botulinum toxin (P < 0.0001) with less significant results thereafter. Predetermined functional goals were achieved in 61% at >18 months. Parents were satisfied in approximately 90% of the cases. Eighteen of 57 children (31.57%) changed Gross Motor Function Classification System status over a mean of 33.8 months (18-48) follow-up. Most significant gains were recorded in the severely involved group IV, where 10 of 15 (66.66%) improved. The high percentage of change in group IV implies the importance of gained sitting balance due to spasticity management.

Improvements in healthcare and cost benefits associated with botulinum toxin treatment of spasticity and muscle overactivity

Spasticity is a widespread, disabling form of muscle overactivity affecting patients with central nervous system damage resulting in upper motor neurone syndrome. There is a range of effective therapies for the treatment of spasticity (e.g. physical, anaesthetic, chemodenervation and neurolytic injections, systemic medication and surgery), but all therapies must be based on an individualized, multidisciplinary programme targeted to achieve patient goals. Appropriate therapy should be based on the extent and severity of spasticity, but spasticity and its consequences, regardless of presentation or cause, are commonly treated with systemic agents. This may be ill-advised as systemic treatment is associated with many undesirable effects. In particular, elderly patients with post-stroke spasticity are at risk from the central adverse effects of systemic medication (e.g. sedation and gait disturbance), which make them more susceptible to falling, with an associated increased risk of fracture. The rising costs of fracture care and its sequelae are fast becoming an international problem contributing to high healthcare expenditure. Botulinum toxin type-A (BoNT-A) treatment is highly effective for some of the more common forms of spasticity and muscle overactivity, and has a favourable profile when compared with systemic agents and other focal treatments. Therefore, the clinical benefits of BoNT-A treatment outweigh the apparent high costs of this intervention, showing it to be a cost-effective treatment.

Whole-body vibration training compared with resistance training: effect on spasticity, muscle strength and motor performance in adults with cerebral palsy

OBJECTIVE

The aim of this study was to evaluate the effect on spasticity, muscle strength and motor performance after 8 weeks of whole-body vibration training compared with resistance training in adults with cerebral palsy.

METHODS

Fourteen persons with spastic diplegia (21-41 years) were randomized to intervention with either whole-body vibration training (n=7) or resistance training (n=7). Pre- and post-training measures of spasticity using the modified Ashworth scale, muscle strength using isokinetic dynamometry, walking ability using Six-Minute Walk Test, balance using Timed Up and Go test and gross motor performance using Gross Motor Function Measure were performed.

RESULTS

Spasticity decreased in knee extensors in the whole-body vibration group. Muscle strength increased in the resistance training group at the velocity 30 degrees /s and in both groups at 90 degrees /s. Six-Minute Walk Test and Timed Up and Go test did not change significantly. Gross Motor Function Measure increased in the whole-body vibration group.

CONCLUSION

These data suggest that an 8-week intervention of whole-body vibration training or resistance training can increase muscle strength, without negative effect on spasticity, in adults with cerebral palsy.

The effectiveness of passive stretching in children with cerebral palsy

Passive stretching is widely used for individuals with spasticity in a belief that tightness or contracture of soft tissues can be corrected and lengthened. Evidence for the efficacy of passive stretching on individuals with spasticity is limited. The aim of this review was to evaluate the evidence on the effectiveness of passive stretching in children with spastic cerebral palsy. Seven studies were selected according to the selection criteria and scored against the Physiotherapy Evidence Database scale. Effect size and 95% confidence intervals were calculated for comparison. There was limited evidence that manual stretching can increase range of movements, reduce spasticity, or improve walking efficiency in children with spasticity. It appeared that sustained stretching of longer duration was preferable to improve range of movements and to reduce spasticity of muscles around the targeted joints. Methods of passive stretching were varied. Further research is required given the present lack of knowledge about treatment outcomes and the wide use of this treatment modality.

Application of combined botulinum toxin type A and modified constraint-induced movement therapy for an individual with chronic upper-extremity spasticity after stroke

BACKGROUND AND PURPOSE

Constraint-induced movement therapy (CIMT) is a promising intervention for retraining upper-extremity function after a stroke. The purpose of this case report is to describe the use of a combination of botulinum toxin type A (BtxA) and a modified CIMT program for a patient with severe spasticity who was unable to use his right upper extremity.

CASE DESCRIPTION

The 52-year-old patient, who had a stroke 4 years ago, did not meet the minimum motor criteria for CIMT benefit. After receiving BtxA injections targeting the elbow, wrist, and finger flexors, he completed a 4-week program of modified CIMT followed by a 5-month home exercise program.

OUTCOMES

The patient exhibited improvement in muscle tone (the velocity-dependent resistance to stretch that muscle exhibits) and in scores on several upper-extremity function tests (Modified Ashworth Scale, Motor Activity Log, Wolf Motor Function Test, Action Research Arm Test, and Fugl-Meyer Assessment of Motor Recovery). He also reported making much progress in the functional use of the involved upper extremity.

DISCUSSION

In a patient with severe flexor spasticity and nonuse of the dominant upper extremity after a stroke, a combined treatment of BtxA and modified CIMT may have resulted in improved upper-extremity use.

DOES FASCICULAR NEUROTOMY HAVE LONG-LASTING EFFECTS?

OBJECTIVE

To determine whether fascicular neurotomy has long-lasting effects on spasticity.

DESIGN

We present 4 clinical cases and a critical analysis of the literature.

PATIENTS

This is a retrospective study on 4 patients referred to our department for spastic equinovarus foot deformity. For all 4, neurotomy was successful not long after surgery, but spasticity reappeared after a few months.

METHODS

We compared our results with those in the PubMed database.

RESULTS

Most publications acknowledge the immediate effectiveness of this surgery, but do not study the long-term effects of neurotomy. No publication proved long-lasting effects of neurotomy for spastic equinovarus foot deformity. The only long-term follow-up with a sufficient population is the one of Berard et al. who reported 61% recurrence.

CONCLUSION

There is no study showing that tibial nerve neurotomy has long-lasting effects. The 4 cases reported are an illustration that recurrence of spasticity may occur after neurotomy. These findings have to be taken into account for treatment decision-making and for provision of information to patients.

FOCAL SPASTICITY THERAPY WITH BOTULINUM TOXIN: EFFECTS ON FUNCTION, ACTIVITIES OF DAILY LIVING AND PAIN IN 100 ADULT PATIENTS

OBJECTIVE

Analysis of the effects of a comprehensive focal spasticity program in adult patients.

DESIGN

Retrospective study of an out-patient cohort.

PATIENTS

One hundred patients were enrolled in the study (54 men and 46 women, mean age 41 years (SD 14). Cerebral palsy and stroke were equally common (80% in total). The remaining patients had miscellaneous diagnoses, including traumatic brain injury.

METHODS

On average 230 units (SD 101) of botulinum toxin A Botox was given for 227 principal therapy targets chosen by the patient or the caregiver. One patient could have several targets for therapy. Administration of botulinum toxin was combined with 260 additional therapeutic interventions, most of which were forms of physical therapy. The effects were assessed after 6 weeks and compared with baseline functional abilities 1-2 weeks prior to therapy.

RESULTS

Improvement was observed for 211 (93%) therapy targets, no change in 15 (7%), and impairment in 1, corresponding to an overall improvement in 90 patients (90%), 9 unchanged (9%) and worsening in 1. Spasticity assessment (Ashworth scale 0-4; 30 patients) showed a statistically significant improvement (median at baseline was 3 vs 2 after therapy, mean difference 1.2, p<0.001).

CONCLUSION

Improvement was observed in >or=90% of patients and in their principal therapeutic targets in a cohort receiving their first focal spasticity treatment with botulinum toxin A and additional therapy. A strict strategy for patient selection and comprehensive management was followed.

Traumatic Brain Injury and Pain

The co-occurrence of traumatic brain injury (TBI) and pain is quite frequent and presents a number of challenges to the medical practitioner. The distinct nature and extent of these challenges calls for considering the co-existence of TBI and pain a unique medical entity. Clearly, from a research standpoint, the area is in its infancy. The clinician is often left with adapting standard techniques effective for evaluating and treating pain in patients without TBI. Such adaptations require a readiness to recognize how pain affects the presence and course of TBI-related symptoms and, in turn, how TBI symptoms affect the presence and course of pain. Given the myriad factors that can affect outcome, effective evaluation and treatment of this co-occurring problem need to rely on a biopsychosocial model, which encourages consideration of a broad perspective of possible causes and care approaches as well as use of multiple disciplines.

Hypoxic brain injury improvement induced by coordination dynamics therapy; a comparison with normal CNS development

A 13-year-old girl suffered a rather severe hypoxic CNS injury and was given up by the school medicine. Adequate therapy was rejected for the patient by a university clinic with the argument that there were only simple reflexes left. The patient underwent coordination dynamics therapy and could significantly improved; she now can sit, walk, eat, drink, count and speak a few words. During a 3-month intensive therapy, a 70% improvement in CNS functioning could be achieved, as quantified by the coordination dynamics, i.e. a similar improvement as could be achieved in patients after stroke and traumatic brain injury, and in cerebral palsy. The improvements in CNS functioning achieved were compared with changes occurring during development in pupils aged between 7 and 19 years. Similarities could be observed with respect to high-frequency exercising for improving CNS functioning, missing continuous concentration on a certain task, and the strong improvement of the coordination dynamics. In the Method section, the theory is presented of the Schalow coordination dynamics therapy.

Influence sur le contrôle postural du traitement par toxine botulique chez les sujets cérébrolésés

OBJECTIVE

To investigate modification of postural control after treatment with botulinum toxine in leg muscles of stroke patients.

METHODS

We performed a retrospective study of stroke patients who benefitted from injection of botulinum toxine in leg muscles between June 2003 and October 2004. The assessment before and after the injection relied on clinical examination and on posturographic recording on 2 force plates with the patient standing, with eyes open performing or not a double task consisting of an arithmetic test and with eyes closed. We also compared patients to healthy subjects.

RESULTS

Eight patients were included in the study. Botulinum toxine injection in the leg muscles significantly decreased the triceps spasticity, with no change in clinical assessment of balance control (Fugl-Meyer scale). The posturographic data show a decrease in the area of centre of pressure displacement in the double-task situation after the injection.

CONCLUSION

Thanks to the posturographic recording in the double-task situation, we showed a modification of postural control after treatment with botulinum toxine in leg muscles of stroke patients.

Reasons for rehospitalization in patients with spinal cord injury: 5 years' experience

The aim of this study was to determine the causes of rehospitalization in patients with spinal cord injury (SCI) treated in Istanbul Physical Medicine and Rehabilitation Centre and to compare the data with previous studies. Patients who were rehospitalized after an initial phase of rehabilitation between 1 January 1996 and 31 December 2001 were enrolled into the study. SCI patients aged 17 years or over at the time of injury were included. This retrospective study was designed using our medical records. In 5 years, 733 SCI patients were treated and 56 of them experienced rehospitalization. We examined the demographic and injury characteristics of rehospitalized patients with SCI. The SPSS computer programme was used for statistical analysis. We found that the rate of rehospitalization was 7.6%, the length of stay (LOS) was 72.21 days and the average age was 34.25 years. The reasons for rehospitalization were, in descending order, spasticity 25%, additional rehabilitation 21.4%, pressure sores 17.9%, urinary infection 16.1%, spinal surgery 8.9%, urinary system surgery 5.4% and pain 5.4%. Statistical significance was found between mean age and causes. The patients who were rehospitalized because of spinal surgery had a lower mean age than those rehospitalized because of pain (P=0.04, F=2.4). The most frequent reasons for rehospitalization of patients over 25 years old were spasticity and pressure sores. In conclusion, SCI patients' LOS was longer than found in previous studies because of a lack of efficient home rehabilitation. The most frequent cause of rehospitalization was spasticity, because of uncontrolled medical therapy. The study demonstrates how education of the patients and their families is important, and that home-based rehabilitation services must be established and supported by government.

Acupuncture for upper-extremity rehabilitation in chronic stroke: a randomized sham-controlled study

OBJECTIVE

To compare the effects of traditional Chinese acupuncture with sham acupuncture on upper-extremity (UE) function and quality of life (QOL) in patients with chronic hemiparesis from stroke.

DESIGN

A prospective, sham-controlled, randomized controlled trial (RCT).

SETTING

Patients recruited through a hospital stroke rehabilitation program.

PARTICIPANTS

Thirty-three subjects who incurred a stroke 0.8 to 24 years previously and had moderate to severe UE functional impairment.

INTERVENTIONS

Active acupuncture tailored to traditional Chinese medicine diagnoses, including electroacupuncture, or sham acupuncture. Up to 20 treatment sessions (mean, 16.9) over a mean of 10.5 weeks.

MAIN OUTCOME MEASURES

UE motor function, spasticity, grip strength, range of motion (ROM), activities of daily living, QOL, and mood. All outcomes were measured at baseline and after treatment.

RESULTS

Intention-to-treat (ITT) analyses found no statistically significant differences in outcomes between active and sham acupuncture groups. Analyses of protocol-compliant subjects revealed significant improvement in wrist spasticity (P<.01) and both wrist (P<.01) and shoulder (P<.01) ROM in the active acupuncture group, and improvement trends in UE motor function (P=.09) and digit ROM (P=.06).

CONCLUSIONS

Based on ITT analyses, we conclude that acupuncture does not improve UE function or QOL in patients with chronic stroke symptoms. However, gains in UE function observed in protocol-compliant subjects suggest traditional Chinese acupuncture may help patients with chronic stroke symptoms. These results must be interpreted cautiously because of small sample sizes and multiple, unadjusted, post hoc comparisons. A larger, more definitive RCT using a similar design is feasible and warranted.

Comparison of Electric Stimulation Methods for Reduction of Triceps Surae Spasticity in Spinal Cord Injury

OBJECTIVES

To compare the effect of 3 methods of electric stimulation to reduce spasticity of the triceps surae in patients with complete spinal cord injury (SCI) and to investigate the carryover effect.

DESIGN

Placebo-controlled study with repeated measurements after the interventions.

SETTING

Research department affiliated with a rehabilitation hospital in the Netherlands.

PARTICIPANTS

Ten patients with a complete SCI were recruited from the outpatient population of the rehabilitation hospital. All subjects had American Spinal Injury Association grade A impairment scores, except for one, who had grade C. The patients had no voluntary triceps surae contractibility.

INTERVENTIONS

Forty-five minutes of cyclic electric stimulation of the agonist, antagonist, or dermatome of the triceps surae or a placebo approach.

MAIN OUTCOME MEASURES

Outcome measures were the Modified Ashworth Scale (MAS), clonus score, and the H-reflex and M wave (H/M) ratio. The electromyographic response to a stretch of the soleus over the whole range of motion was also determined. The magnitude and ankle angle at which the electromyographic response started were calculated.

RESULTS

Stimulation of the agonist provided a significant reduction in the MAS compared with the placebo approach (P<.001). There was no significant change in the H/M ratio or the electromyographic response amplitude after any of the stimulation methods, whereas stimulation of the antagonist muscle resulted in a significant reduction in the ankle angle at which the electromyographic response started, compared with the placebo approach (P<.037).

CONCLUSIONS

Triceps surae stimulation reduces the MAS for that specific muscle, whereas the angle at which the reflex starts changes after antagonist stimulation.

Defining the Bobath concept using the Delphi technique

BACKGROUND AND PURPOSE

The Bobath concept, based on the work of Berta and Karel Bobath, offers therapists working in the field of neurological rehabilitation a framework for their clinical interventions. It is the most commonly used approach in the UK. Although they recognize that over the last half-century the concept has undergone considerable developments, proponents of the Bobath concept have been criticized for not publishing these changes. The aim of the present study was to use the Delphi technique to enable experts in the field to define the current Bobath concept.

METHOD

A four-round Delphi study design was used. The sample included all members of the British Bobath Tutor's Association, who are considered experts in the field. Initial statements were identified from the literature, with respondents generating additional statements during the study. The level of agreement was determined using a five-point Likert scale. The respondents were then provided with feedback on group opinions and given an opportunity to re-rate each statement. The level of group consensus was set at 80%.

RESULTS

Fifteen experts took part. The response rate was 85% in the first round, and 93% in each subsequent round. Ten statements from the literature were rated with a further 12 generated by the experts. Thirteen statements achieved consensus for agreement and seven for disagreement.

CONCLUSIONS

The Delphi study was an effective research tool, maintaining anonymity of responses and exploring expert opinions on the Bobath concept. The experts stated that Bobath's work has been misunderstood if it is considered as the inhibition of spasticity and the facilitation of normal movement, as described in some literature. They agreed that the Bobath concept was developed by the Bobaths as a living concept, understanding that as therapists' knowledge base grows their view of treatment broadens.

The effect of positioning for children with cerebral palsy on upper-extremity function: a review of the evidence

CONTEXT

Controversy exists about the most appropriate seating position for children with cerebral palsy (CP) to promote energy conservation and maximize upper-extremity function.

EVIDENCE ACQUISITION

Sixteen journal articles published after 1980 were identified by searching allied health, medical, and occupational and physical therapy data bases and evidence-based medicine reviews using specific key terms (positioning, wheelchair, postural control, posture, adaptive seating devices, patient positioning, cerebral palsy, movement disorders, upper extremity, reaching, grasping, and occupational therapy) and reviewing bibliographies of retrieved articles.

EVIDENCE SYNTHESIS

The majority of the evidence supports the positive effects of a neutral to slightly forward orientation (whole chair tilted) on upper-extremity function. Only one study did not demonstrate such effects. Of the supporting studies, one suggested the addition of an abduction orthrosis (AO), one recommended the entire functional sitting position (FSP) package (this orientation plus a hip-belt, footrests, AO, and cutout tray), and one established the long-term effects of the FSP. One less rigorous study opposed the addition of an AO. With the exception of one study, most of the evidence states that seat angle does not affect functional abilities. However, some of these studies contain faulty methodology and/or their results demonstrate clinical significance.

CONCLUSION

Evidence supports that children with CP should be fitted for wheelchairs that place them in a FSP, which includes; orientation in space of 0 degrees -15 degrees, a hip-belt, an AO, footrests, and a cutout tray, with the addition of a sloped forward seat of 0 degrees -15 degrees, to improve upper-extremity function. The exact seat angle and orientation in space within the 0 degrees -15 degrees range should be determined on an individual basis.

Effects of neuromuscular electrical stimulation treatment of cerebral palsy on potential impairment mechanisms: a pilot study

PURPOSE

This pilot study examined the effects of neuromuscular electrical stimulation (NMES) therapy on upper limb impairment in children with cerebral palsy, specifically addressing spasticity, heightened passive resistance to wrist rotation, coactivation, and weakness.

METHODS

Eight subjects, aged five to 15 years, with spastic hemiparesis subsequent to brain injury, participated in three months of NMES therapy, targeting the wrist flexor and extensor muscles. Maximum voluntary wrist extension range of motion against gravity, spasticity, passive torque, maximum voluntary isometric torque, and coactivation were recorded prior to, during, and at the conclusion of the therapy.

RESULTS

Seven of the eight subjects demonstrated a significant (>15 degrees) improvement in wrist extension range of motion against gravity following the NMES treatment, with an average gain of 38 degrees. Differences in spasticity (0.01 +/- 0.14 N-m, p = 0.80) and passive torque (0.03 +/- 0.11 N-m, p = 0.52) were not significant for these subjects. Isometric wrist extension torque, however, did increase significantly (p < 0.01), accompanied by a reduction in flexor coactivation (p < 0.01).

CONCLUSIONS

Evidence suggests that the NMES treatment protocol affected wrist extension by improving the strength of the wrist extensor muscles, possibly through decreased flexor coactivation. Further studies are required, however, to determine whether electrical stimulation itself or other facets of the therapy paradigm played the key role in improvement.

The use of botulinum toxin in physical medicine and rehabilitation

A review of the history and pharmacology of the botulinum neurotoxins is presented. Established mechanisms of action are discussed as well as preliminary evidence of other potential mechanisms, as related to botulinum toxins' antinociceptive properties. Methods of administration, including reconstitution, dilution, and basic injection techniques/principles are reviewed. Safety concerns are also addressed. Various applications relevant to the field of Physical Medicine & Rehabilitation are reviewed, specifically uses in the management of muscle over activity syndromes such as upper motor neuron-related spasticity, dystonias, and painful syndromes including Myofascial Pain Syndromes and headaches. Relevant literature related to these applications is reviewed and discussed. Botulinum toxin therapeutic efficacy and possible reasons for treatment failure (including development of antibody-mediated resistance) are discussed.

Gluteal taping improves hip extension during stance phase of walking following stroke

The aim of this study was to determine whether gluteal taping on the affected side improved hip extension during stance phase of walking for persons following stroke. Fifteen subjects who had suffered a stroke months to years previously resulting in mild to moderate gait impairments participated in the study. Their gait was measured under control, sham, and gluteal taping conditions, in random order. For each condition, subjects walked at a self-selected and a fast speed. Hip angle relative to that obtained during quiet standing, step length, stride length and walking velocity were measured. Hip extension increased significantly with gluteal taping (p < 0.05) for both walking speeds at late stance phase of walk compared to sham taping and control. The mean absolute difference between gluteal and control conditions for self-selected velocity was 14.2 degrees (95% CI 8.6 to 19.8) whereas the difference between sham and control conditions was 2.0 degrees (95% CI -2.0 to 6.0). Also, for both speeds, step length on the unaffected side increased significantly with gluteal taping compared with either the control or placebo conditions. The absolute difference between gluteal taping and control conditions at self-selected velocity was 3.3 cm (95% CI 2.2 to 4.3) and between sham and control conditions was 0.6 cm (95% CI -0.8 to 1.9). Affected step length and walking velocity, however, remained unchanged. Lastly, there was no significant difference between the control and sham taping condition for any of the measured variables. Gluteal taping may be a useful adjunct to current rehabilitation gait training strategies.

Feedback-Controlled and Programmed Stretching of the Ankle Plantarflexors and Dorsiflexors in Stroke: Effects of a 4-Week Intervention Program

OBJECTIVE

To investigate the effect of repeated feedback-controlled and programmed "intelligent" stretching of the ankle plantar- and dorsiflexors to treat subjects with ankle spasticity and/or contracture in stroke.

DESIGN

Noncontrolled trial.

SETTING

Institutional research center.

PARTICIPANTS

Subjects with spasticity and/or contracture after stroke.

INTERVENTIONS

Stretching of the plantar- and dorsiflexors of the ankle 3 times a week for 45 minutes during a 4-week period by using a feedback-controlled and programmed stretching device.

MAIN OUTCOME MEASURES

Passive and active range of motion (ROM), muscle strength, joint stiffness, joint viscous damping, reflex excitability, comfortable walking speed, and subjective experiences of the subjects.

RESULTS

Significant improvements were found in the passive ROM, maximum voluntary contraction, ankle stiffness, and comfortable walking speed. The visual analog scales indicated very positive subjective evaluation in terms of the comfort of stretching and the effect on their involved ankle.

CONCLUSIONS

Repeated feedback-controlled or intelligent stretching had a positive influence on the joint properties of the ankle with spasticity and/or contracture after stroke. The stretching device may be an effective and safe alternative to manual passive motion treatment by a therapist and has potential to be used to repeatedly and regularly stretch the ankle of subjects with spasticity and/or contracture without daily involvement of clinicians or physical therapists.

Application of a Volar Static Splint in Poststroke Spasticity of the Upper Limb

OBJECTIVE

To evaluate clinical and neurophysiologic effects of 3-month reflex inhibitory splinting (RIS) for poststroke upper-limb spasticity.

DESIGN

Pretest-posttest trial.

SETTING

Outpatient rehabilitation center.

PARTICIPANTS

Forty consecutive patients with hemiplegia and upper-limb spasticity after stroke that had occurred at least 4 months before.

INTERVENTION

Patients wore an immobilizing hand splint custom-fitted in the functional position for at least 90 minutes daily for 3 months.

MAIN OUTCOMES MEASURES

Patients underwent measurement of (1) spasticity at the elbow and wrist according to Modified Ashworth Scale; (2) passive range of motion (PROM) at the wrist and elbow; (3) pain at the shoulder, elbow, and wrist using a visual analog scale; (4) spasms; and (5) comfort and time of splint application. The instrumental measure of spasticity was the ratio between the maximum amplitude of the H-reflex and the maximum amplitude of the M response (Hmax/Mmax ratio).

RESULTS

A significant improvement of wrist PROM (F=8.92, P=.001) with greater changes in extension than in flexion, and a reduction of elbow spasticity (F=5.39, P=.002), wrist pain (F=2.89, P=.04), and spasms (F=4.33, P=.008) were observed. The flexor carpi radialis Hmax/Mmax ratio decreased significantly (F=4.2, P=.007). RIS was well tolerated.

CONCLUSIONS

RIS may be used as an integrative treatment of poststroke upper-limb spasticity. It can be used comfortably at home, in selected patients without functional hand movements, and in cases of poor response or tolerance to antispastic drugs.

The effects of isotonic and isokinetic muscle stretch on the excitability of the spinal alpha motor neurones in patients with muscle spasticity

To examine the effect of isotonic (with and without weight bearing) and isokinetic muscle stretch on the excitability of the spinal alpha motor neurones (alphaMN) in patients with spasticity and to establish whether this effect is maintained for at least 24 h after the intervention. A single 20-min session of isotonic muscle stretch (with or without weight bearing) or isokinetic stretch was delivered to the ankle plantar flexors in patients with post-stroke lower limb spasticity and healthy control subjects. The effect of these types of muscle stretch on the excitability of alphaMN was assessed by measuring the latency of the Hoffmann reflex (H-reflex) and the ratio of the amplitude of the maximum H-reflex (H(max)) to that of the maximum action motor potential of the soleus muscle (M(max)). Sixty-six hemiplegic stroke patients and 21 healthy control subjects were recruited and completed the trial. The H(max):M(max) ratio was significantly higher in patients with spasticity than in healthy control subjects. However, there were no statistically significant differences in the H-reflex latency or the change in H(max):M(max) ratio between the baseline values and those recorded immediately after the therapy intervention or 24 h later for each type of muscle stretch. Similarly, there were no significant differences in these variables between the interventions. In the present study neither isotonic muscle stretch (with or without weight bearing) or isokinetic stretch had a statistically significant effect on the excitability of the alphaMN in patients with muscle spasticity. This suggests that the previously reported reduction in spasticity after muscle stretch is because of mechanisms other than the direct effect on alphaMN. However, the lack of a demonstrable benefit of treatment may be due the fact that we examined the effects of a single, rather than repeated treatment cycles.

Assessment of the short-term effect of antispastic positioning on spasticity

BACKGROUND

This study was performed in order to investigate the effect of antispastic positioning on spasticity by using different assessment methods.

METHODS

A total of 16 patients (11 males [68.75%] and five females [31.25%]), diagnosed as spastic diplegic and referred to the School of Physical Therapy and Rehabilitation, Paediatric Rehabilitation Unit for treatment, were included in this study. The mean age of patients was 6.43 +/- 1.99 years (range, 4-13 years). Passive dorsi-flexion movement was measured by using goniometer and intensity of spasticity was determined by using Modified Ashworth Scale (MAS) and electromyography. For the objective measurement of severity of spasticity, Hoffman reflex (H) and Hoffman reflex/motor response (H/M) ratios were used. Children were placed in an antispastic position for 20 min. The patient was placed in a sitting position, by a physiotherapist, with hips abducted at a 45 degrees angle and externally rotated, knees extended, and ankles placed in a neutral position.

RESULTS

The decrease in H responses, H/M ratios, MAS values and the increase in goniometric measurement values were found statistically significant after antispastic positioning (P < 0.05).

CONCLUSION

Our study supports that antispastic positioning can be used with neurodevelopmental treatment approaches when it is required. Antispastic positioning may help exercises to be performed more easily, and also has importance in a home exercise program to prevent muscle contractures and joint limitation in children with long-term spastic diplegia.

Monitoring standing wheelchair use after spinal cord injury: a case report

PURPOSE

An important issue in spinal cord injury (SCI) research is whether standing can yield positive health benefits. However, quantifying dose of standing and establishing subject compliance with a standing protocol is difficult. This case report describes a method to monitor dose of standing outside the laboratory, describes the standing patterns of one subject, and describes this subject's satisfaction with the standing protocol.

METHOD

A man with T-10 complete paraplegia agreed to have his commercially available standing wheelchair instrumented with a custom-designed logging device for a 2-year period. The micro-controller-based logger, under custom software control, was mounted to the standing wheelchair. The logger recorded date, duration, angle of standing, and start/stop times.

RESULTS

The client exceeded a suggested minimum dosage of standing per month (130.4% of goal), choosing to stand for short bouts (mean = 11.57 min) at an average angle of 61 degrees, on an average 3.86 days per calendar week. He was generally very satisfied with the standing device and provided subjective reports of improved spasticity and bowel motility.

CONCLUSION

This case report describes a standing and surveillance system that allow quantification of standing dose. Future controlled studies are needed to evaluate whether standing can be beneficially affect secondary complications after SCI.

Cost-effectiveness of botulinum toxin type a in the treatment of post-stroke spasticity

OBJECTIVE

Treatment strategies for post-stroke spasticity include oral anti-spastic drugs, surgery, physiotherapy and botulinum toxin type A injection. The objective of this study was to compare the cost-effectiveness and outcomes of oral therapy vs. botulinum toxin type A treatment strategies in patients with flexed wrist/clenched fist spasticity.

METHODS

Treatment outcome and resource use data were collected from an expert panel experienced in the treatment of post-stroke spasticity. A decision tree model was developed to analyse the data.

RESULTS

Thirty-five percent of patients receiving oral therapy showed an improvement in pre-treatment functional targets which would warrant continuation of therapy, compared with 73% and 68% of patients treated with botulinum toxin type A first- and second-line therapy, respectively. Botulinum toxin type A treatment was also more cost-effective than oral therapy with the "cost-per-successfully-treated month" being 942 pounds, 1387 pounds and 1697 pounds for botulinum toxin type A first-line, botulinum toxin type A second-line and oral therapy, respectively.

CONCLUSION

In conclusion, botulinum toxin type A is a cost-effective treatment for post-stroke spasticity.

Spastic equinus foot: multicenter study of the long-term results of tibial neurotomy

OBJECTIVE

Tibial neurotomy is a surgical technique widely used for the treatment of spastic equinus foot, but it has rarely been evaluated. The primary objective of this prospective study was to provide an objective quantification of the long-term results of tibial neurotomy.

METHODS

This multicenter prospective study was conducted from 1999 to 2003. Fifty-five patients with spastic equinus foot were treated in five neurosurgical centers. Preoperative and postoperative clinical evaluation comprised description of the foot deformity, study of stretch reflexes, evaluation of the repercussions of the deformity, and gait analysis. Selective neurotomy was performed in all patients.

RESULTS

No postoperative complications were observed. The mean postoperative follow-up was 10 months. Tibial neurotomy improved the appearance of the foot (equinus and varus deformities, claw toes); the equinus score decreased from 1.54 to 0.273 after the operation. Stretch reflex scores were decreased significantly and for a long term after surgery; the mean triceps surae stretch reflex score decreased from 2.46 to 0.47. The angle of passive dorsiflexion of the ankle increased significantly (from -0.56 degrees to +6.85 degrees). Gait analysis demonstrated a statistically significant increase in the speed of the patient's gait after surgical treatment; the time taken by the patient to walk 10 m at a normal speed in shoes decreased from a mean of 55 seconds to 35.16 seconds. Postoperatively, 92.7% of preoperative objectives had been achieved.

CONCLUSION

Tibial neurotomy ensures long-term functional improvement of patients with spastic equinus foot. It provides a lasting response for these patients compared with other, more transient treatments.

Multiple Sclerosis and Spasticity

Spasticity is a common impairment in MS. It can result in significant medical complications and is associated with increased disability. Treatment strategies include skilled rehabilitation strategies, neuromuscular blocks, oral agents, intrathecal management, and surgery. Rehabilitation strategies are central, whereas other strategies are added based on the level of impairment and functional loss. Treatment strategies for spasticity management are far from optimal and are complicated in MS as a result of lesions in the brain and the spinal cord. Pharmaceutical management in MS is complicated by the numerous secondary impairments in MS and its associated polypharmacy.Head-to-head studies of the various agents are rare. The studies that exist are small and do not point to any one strategy over another. Although management is difficult, it is essential for the health, functional status, and well-being of the individual who has MS. Providers must use well-developed clinical skills to arrive at optimal individualized treatment programs and monitor them frequently. For spasticity that is unresponsive, referral to a MS Center with a spasticity program is ideal.

The influence of contractures and variation in measurement stretching velocity on the reliability of the Modified Ashworth Scale in patients with severe brain injury

OBJECTIVE

To determine the influence of contractures and different stretching velocities on the reliability of the Modified Ashworth Scale (MAS) in patients with severe brain injury and impaired consciousness.

DESIGN

Cross-section observational study.

SETTING

A rehabilitation centre for adult persons with neurological disorders.

SUBJECTS

Fifty patients with impaired consciousness due to severe cerebral damage of various aetiologies. MEASUREMENT PROTOCOL: Three experienced and trained medical professionals rated each patient in a randomized order once daily for two consecutive days. Shoulder, elbow, wrist, knee and ankle spasticity were assessed by the use of the MAS with different stretching velocities. The presence of contractures was assessed by a goniometer.

MAIN OUTCOME MEASURES

Retest and inter-rater reliability (k(w) = weighted kappa) of the MAS.

RESULTS

The retest reliability of the MAS was good (shoulder joints (k(w) 0.74), elbow joints (k(w) 0.74), wrist joints (k(w) 0.72), knee joints (k(w) 0.72), ankle joints (k(w) 0.77)) and the inter-rater reliability was moderate (shoulder joints (k(w) 0.49), elbow joints (k(w) 0.52), wrist joints (k(w) 0.51), knee joints (k(w) 0.54) ankle joints (k(w) 0.49)). The presence of contractures significantly influenced the reliability of MAS in shoulder and wrist joints. No influence of stretching velocity on the reliability of the MAS was found.

CONCLUSION

In patients with impaired consciousness due to severe brain injury the MAS has good retest, but only limited inter-rater, reliability. The presence of contractures may influence reliability of the MAS, but stretching velocity does not.

The effect of passive cycling movements on spasticity after spinal cord injury: preliminary results

OBJECTIVE

To investigate the influence of rhythmic passive movements of the legs on the reduction of spasticity after spinal cord injury (SCI).

SETTING

Swiss Paraplegic Centre Nottwil, Switzerland.

METHODS

A total of 10 subjects with motor complete SCI were treated with a cycling device for half an hour. Before and after cycling their spasticity was tested with an isokinetic dynamometer. The subjects were tested one week later by exactly the same procedure with a half an hour break instead of the cycling. Subjects were asked about their spasticity before and after the cycling and break.

RESULTS

There was no significant difference in elicited peak torque either before and after the cycling, or before and after the break (MANOVA, P<0.05). Six out of 10 subjects estimated their spasticity as less after the cycling.

CONCLUSION

With the isokinetic dynamometer, it was not possible to show an effect of passive cycling on spasticity reduction. However, six out of 10 of the subjects estimated their spasticity to be less after cycling. This positive effect might be attributed to a reduced spasticity in the trunk and/or to the attention the subjects perceived during the intervention.

The efficacy of diazepam in enhancing motor function in children with spastic cerebral palsy

Muscle spasm and hypertonia limit mobility in children with spastic cerebral palsy. This double-blind, placebo-controlled, randomized controlled clinical trial studies the clinical efficacy of a low dose of diazepam in enhancing movement in children with spastic cerebral palsy. One hundred and eighty children fulfilled the criteria and were randomly allocated to receive one of two doses of diazepam or placebo at bedtime; 173 completed the study. There was a significant reduction of hypertonia, improvement in the range of passive movement, and an increase in spontaneous movement in the children who received diazepam. There was no report of daytime drowsiness. In developing countries, where cost factors often determine choice of drug, diazepam is a cheap and effective way of relieving spasm and stiffness, optimizing physical therapy and facilitating movement in children with spasticity.

Relationship between ambulatory capacity and cardiorespiratory fitness in chronic stroke: influence of stroke-specific impairments

STUDY OBJECTIVES

To identify the following in individuals with chronic stroke: (1) the relationship between the maximal oxygen consumption (Vo(2)max) during cycle ergometry and the distance covered in the 6-min walk test (6MWT), and (2) the stroke-specific impairments that are important determinants for the 6MWT distance.

DESIGN

Cross-sectional study using a convenience sample.

SETTING

Exercise testing laboratory in a tertiary rehabilitation center.

PARTICIPANTS

Sixty-three older adults (mean age +/- SD, 65.3 +/- 8.7 years) with an average poststroke interval of 5.5 +/- 4.9 years.

INTERVENTION

Not applicable.

MAIN OUTCOME MEASURES

Each subject underwent a maximal cycle ergometer test and a 6MWT. Oxygen consumption (Vo(2)) was measured during both tests. Subjects were also evaluated for Berg balance scale, modified Ashworth scale of spasticity, isometric knee extension strength, and percentage of body fat.

RESULTS

The 6MWT distance had a low correlation with the Vo(2)max (r = 0.402). Balance, knee extension strength, and spasticity were all significant determinants for the 6MWT distance, with balance being the major contributor for the 6MWT distance, accounting for 66.5% of its variance.

CONCLUSIONS

Factors other than the cardiorespiratory status considerably influenced the ambulatory capacity as measured by the 6MWT. The 6MWT distance alone should not be used to indicate cardiorespiratory fitness in individuals with chronic stroke.

The Drawing Test: Assessment of coordination abilities and correlation with clinical measurement of spasticity

OBJECTIVE

To assess the correlation between kinematic measures of movement (Drawing Test) and a clinical measure of spasticity (Ashworth Scale).

DESIGN

Correlation study of Drawing Test and the Ashworth Scale scores.

SETTING

Inpatient rehabilitation center.

PARTICIPANTS

Forty-five poststroke hemiplegic subjects with various levels of spasticity (up to Ashworth Scale score of 3) and 8 able-bodied subjects with no sensorimotor deficits in their upper extremities.

INTERVENTIONS

Subjects made self-paced, radial point-to-point movements between the left, and the right corners of a square (200 x 200 mm) on the surface of a drawing tablet. Hand coordinates were recorded from the mouse, which was attached to the hand.

MAIN OUTCOME MEASURES

Correlation between (1) Drawing Test scores (time to perform the movement, radial [ y ] and tangential [ x ] distances between the end point of the movement and the target endpoint, standard error of the mean calculated as distances between the recorded path and its radial linear fit), and (2) Ashworth Scale scores.

RESULTS

Drawing Test scores correlated highly with Ashworth Scale scores in 49 of 53 subjects, based on the multiple linear regression analysis.

CONCLUSIONS

The Drawing Test, a quantitative metric of movement ability, correlated highly to the Ashworth Scale, a clinical measure of spasticity.

The effect of hinged ankle-foot orthoses on sit-to-stand transfer in children with spastic cerebral palsy

OBJECTIVE

To investigate the effectiveness of the hinged ankle-foot orthosis (AFO) on sit-to-stand (STS) transfers in children with spastic cerebral palsy.

DESIGN

Before-after trial.

SETTING

University-affiliated hospital.

PARTICIPANTS

Nineteen spastic diplegic children (age range, 2-6 y).

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURES

The transitional movement of STS was tested in random order with children while wearing the barefoot and hinged AFOs. The temporal, kinematic, and kinetic data during the task were collected by using a motion analyzer (with 6 infrared cameras). Statistical comparison between barefoot and hinged AFO was done with the Wilcoxon signed-rank test.

RESULTS

Total duration of STS transfer was significantly shortened with the hinged AFO (P <.05). The initial knee flexion, the initial angle, and the final angle of ankle dorsiflexion were increased with the AFO, compared with when barefoot (P <.05). However, the increased pelvic tilt and hip flexion while barefoot was not reduced with the AFO. The maximal moment and power of hip and knee joints were significantly increased with the AFO (P <.05), whereas the maximal moment and power of the ankle joint were not significantly changed when wearing the AFO.

CONCLUSIONS

Although proximal compensatory strategy of increased pelvic tilt and hip flexion did not change with the hinged AFO, some improvements of temporal, kinematic, and kinetic parameters were identified during the task. These findings suggest that a hinged AFO is beneficial for STS transfer activity for children with spastic diplegia.

Microswitch clusters to support responding and appropriate posture of students with multiple disabilities: three case evaluations

PURPOSE

This study extended the evaluation of microswitch clusters to support responding and appropriate posture with three students with multiple disabilities.

METHOD

Initially, a baseline level was established for the target response selected for each student. Then, Intervention I was implemented to increase the frequency of that response through the presentation of favourite stimuli. During Intervention II, the response was followed by favourite stimuli only if the microswitch cluster detected it in combination with appropriate posture. Post-intervention checks were carried out within 2 or 3 months from the end of Intervention II.

RESULTS AND CONCLUSIONS

All students showed an increase in the frequency of the target response during Intervention I and in the percentage of times the response occurred in combination with appropriate posture during Intervention II. These changes lasted over time. The importance of microswitch clusters to enhance the performance of students with multiple disabilities was underlined.

The effect of selective tibial neurotomy and rehabilitation in a quadriplegic patient with ankle spasticity following traumatic brain injury

Ankle spasticity following brain injury leads to abnormal posture and joint contracture; making standing or walking impossible. This study investigates the efficacy of selective tibial neurotomy (STN) and intensive rehabilitation in a patient who suffered ankle spasticity after brain injury. This case describes a 37-year-old man whose traumatic brain injury (TBI) resulted in severe right ankle spasticity and contracture. He was unable to stand due to severe right ankle spasticity and contracture. Intensive rehabilitation and STN allowed him to walk without brace at 6 months and run at 12 months after STN. STN is an effective procedure to resolve localized spasticity of the ankle and it may be considered as a management strategy after local injection to alleviate ankle spasticity and/or contracture prior to orthopaedic surgery.

Changes of reflex size in upper limbs using wrist splint in hemiplegic patients

We evaluated the effect of prolonged wrist extension on H reflex in the flexor carpi radialis (FCR) muscle and tendon jerk (T) reflex in the biceps brachii (BB) muscle of 17 chronic hemiplegic patients. H reflex of the FCR and T reflex of the BB were assessed every 5 minutes within 20 minutes during prolonged wrist extension and post-20 minutes after the extension. As a result, H reflex in the FCR was reduced by passive wrist stretch in 82% of the spastic limbs. The effect was larger in the higher spastic group. In 45% of the spastic limbs, T reflex in the BB also was reduced by passive wrist stretch. The inhibitory effects had a tendency to strengthen in accordance with the grade of muscle tone. We considered from these results, prolonged wrist extension generated inhibitory projections via probably group II afferents of the FCR in the homonym and in the transjoint in spastic limbs.

Poststroke motor dysfunction and spasticity: novel pharmacological and physical treatment strategies

Following stroke, approximately 90% of patients experience persistent neurological motor deficits that lead to disability and handicap. Both pharmacological and physical treatment strategies for motor rehabilitation may be considered. In terms of pharmacological treatment, drugs that may potentially promote motor recovery when added to a regimen of physical therapy include the stimulants amphetamine and methylphenidate, as well as levodopa and fluoxetine. Botulinum toxin A has proven effective and well tolerated in several placebo-controlled trials for the treatment of focal upper and lower limb spasticity, although it has not been shown to improve motor function. The focal injection of botulinum toxin A inhibits the release of acetylcholine into the synaptic cleft, resulting in a reversible paresis of the muscles relevant for the spastic deformity. Other drugs, such as benzodiazepines, antiepileptic drugs and antipsychotics, may have detrimental effects on motor function and should be avoided, if possible. With respect to physical strategies, modern concepts of motor learning favour a task-specific repetitive approach that induces skill-acquisition relevant to the patient's daily life. Constrained-induced movement therapy based on the concept of learned non-use, electromyography-triggered electrical stimulation of the wrist muscles, robot-assisted motor rehabilitation to increase therapy intensity and bilateral practice to facilitate the movement of the paretic extremity are examples in upper limb rehabilitation. Lower limb rehabilitation has been enriched by treadmill training with partial bodyweight support, enabling the practice of up to 1000 steps per session; automated gait rehabilitation to relieve the strenuous effort required of the therapist; and rhythmic auditory stimulation, applying individually adjusted music to improve walking speed and symmetry.

Selective blocks of the motor nerve branches to the soleus and tibialis posterior muscles in the management of the spastic equinovarus foot11No commercial party having a direct financial interest in the results of the research supporting this article has conferred or will confer a financial benefit on the author(s) or on any organization with which the author(s) is/are associated

OBJECTIVE

To identify the location of the motor nerve branches to the soleus and tibialis posterior muscles in relation to anatomic surface landmarks for selective motor nerve blocks in the management of the spastic equinovarus foot.

DESIGN

Descriptive study by computed tomography (CT) scan of 12 hemiplegic legs.

SETTING

Spasticity group at a university hospital.

PARTICIPANTS

Twelve patients with hemiplegia (6 men, 6 women) with spastic equinovarus foot.

INTERVENTION

Three-dimensional location of the motor nerve branches to the soleus and tibialis posterior muscles with CT scan, followed by selective motor branch blocks with anesthetics.

MAIN OUTCOME MEASURES

Vertical, horizontal, and deep coordinates determined by CT scan in relation to anatomic surface landmarks (upper extremity of the fibula and vertical metallic element). Soleus and tibialis posterior spasticity (Ashworth Scale), soleus H-wave maximum (Hmax)/M-wave maximum (Mmax) ratio, and sensory testing before and after the blocks.

RESULTS

The mean coordinates +/- standard deviation for the soleus motor branch were 10+/-5 mm (vertical), 17+/-9 mm (horizontal), and 30+/-4 mm (deep); for the tibialis posterior motor branch they were 45+/-6mm (vertical), 17+/-8mm (horizontal), and 47+/-4 mm (deep). Spasticity and Hmax/Mmax ratio decreased after the blocks, confirming their efficiency. No subjects experienced additional sensory deficit.

CONCLUSION

Our study determined the location of the motor nerve branches to the soleus and tibialis posterior muscles in relation to anatomic surface landmarks for selective motor branch blocks and neurolytic procedures. These coordinates allow us to perform selective motor blocks without CT scan.

Outcome Assessment for Spasticity Management in the Patient With Traumatic Brain Injury

The objective of this article was to (1) review the engineering and medical literature to structure the available information concerning the assessment of spasticity in the neurological population; (2) to discuss the strengths and weaknesses of the different methods currently in use in spasticity assessment; and (3) make recommendations for future efforts in spasticity outcome assessment. Spasticity textbooks, Web sites, and OVID, IEEE, and Medline searches from 1966 through 2003 of spasticity, quantitative measure, or outcome assessment in the rehabilitation population were used as data sources. Over 500 articles were reviewed. Articles that discussed outcome measures used to assess interventions and evaluation of spasticity were included. Authors reviewed the articles looking at inclusion criteria, data collection, methodology, assessment methods, and conclusions for validity and relevance to this article. Issues such as clinical relevance, real-world function and lack of objectivity, and time consumed during performance are important issues for spasticity assessment. Some measures such as the Ashworth Scale remain in common use secondary to ease of use despite their obvious functional limitations. More functional outcome goals are plagued by being more time consuming and a general inability to demonstrate changes after an intervention. This may be secondary to the other factors that combine with spasticity to cause dysfunction at that level. Quantitative metrics can provide more objective measurements but their clinical relevance is sometimes problematic. The assessment of spasticity outcome is still somewhat problematic. Further work is necessary to develop measures that have real-world functional significance to both the individuals being treated and the clinicians. A lack of objectivity is still a problem. In the future it is important for clinicians and the engineers to work together in the development of better outcome measures.

Placement of a Plate Under the Forefoot in Stance

OBJECTIVE

To investigate the effect of the placement of a plate under the sole of the forefoot on the excitability of the soleus motoneuron pool in stance.

DESIGN

While eight neurologically intact subjects remained in stance, a square plate (30 x 30 mm), either 3 mm or 6 mm in thickness, was placed under the left medial plantar eminence, under the left lateral plantar eminence, or under the left forefoot sole between the eminences, or a rectangular plate (120 x 30 mm), either 3 mm or 6 mm in thickness, was placed under the left metatarsal heads. To investigate the excitability of the soleus motoneuron pool, the Hmax/Mmax ratio was estimated.

RESULTS

Analysis of variance revealed that the region under which the plate was placed had a significant effect and that the thickness of the plate had a nonsignificant effect on the Hmax/Mmax ratio, without significant interaction between the two factors. Post hoc analysis revealed a significant decrease in the Hmax/Mmax ratio when the square plate was placed under the lateral plantar eminence.

CONCLUSIONS

A square plate placed under the lateral plantar eminence inhibited the excitability of the ipsilateral soleus motoneuron pool in stance. This intervention may be useful for reducing spasticity.

The role of neurosurgical interventions for control of spasticity in neurorehabilitation: new findings on functional microanatomy of the tibial nerve

Harmful spasticity after cerebral or spinal damage disturbs functional recovery in neurorehabilitation, but neurosurgical interventions for relief of spasticity are not widely performed, at least in Asian countries including Japan. We have been performing various types of neurosurgical treatment for spasticity such as selective peripheral neurotomy, selective dorsal rhizotomy, microsurgical DREZotomy, and intrathecal baclofen administration. We deal with both children and adults. From our experience of tibial neurotomy, in particular, we describe functional microsurgical anatomy of the tibial nerve in the popliteal fossa. This is the first report on this regional functional anatomy.

The short-term effect of hippotherapy on spasticity in patients with spinal cord injury

STUDY DESIGN

Assessment of spasticity before and after hippotherapy treatment.

OBJECTIVE

To evaluate the short-term effect of hippotherapy on spasticity of spinal cord injured patients (SCIs).

SETTING

Swiss Paraplegic Centre, Nottwil.

METHODS

32 patients with spinal cord injury with various degrees of spasticity had repeated sessions (mean 11) of Hippotherapy-K. Spasticity of the lower extremities was scored according to the Ashworth Scale.

RESULTS

In primary rehabilitation patients Ashworth values after hippotherapy were significantly lower than before (Wilcoxon's signed-rank test: P<0.001). Highest improvements were observed in SCIs with very high spasticity. No significant difference between short-term effect in paraplegic and short-term effect in tetraplegic subjects was found.

CONCLUSIONS

Hippotherapy significantly reduces spasticity of lower extremities in SCIs.
