Enhanced independence: experiences after regaining grip function in people with tetraplegia

[Surgical reconstruction of arm and hand functions in tetraplegia : Current concepts]

The reconstruction of arm and hand functions is of enormous importance for tetraplegic patients as it enables at least some degree of independence. Depending on the level of the spinal cord injury, certain residual functions are present in the arms which can be used for surgical reconstruction of upper extremity functions. By utilizing tendon and nerve transfers missing functions can at least be partially reconstructed. Tendon transfers are a proven technique with reliable results that can be performed at any time regardless of the type of accident. Due to the frequent presence of lower motor neuron damage, it is essential to consider the optimal time window for nerve transfer interventions. From the multitude of surgical options, an individual reconstruction plan must be created for each patient, which considers multiple factors. The combination of nerve transfers and later completing the functional reconstruction by tendon transfers is the preferred concept of the authors of this article.

Restoration of elbow extension and construction of a "key grip" in people with tetraplegia. Comparative study of a surgical plan in one or two stages

AIM

We report the comparative results of functional upper extremity surgery plans in patients with tetraplegia, including restoration of elbow extension and construction of a key grip in a "one-stage" or "two-stage" operation.

MATERIALS AND METHODS

A series of 36 patients with tetraplegia, with a total of 45 operated upper limbs, was analyzed retrospectively with a mean follow-up of 23 months (13-39 months). We evaluated the analytical strength of elbow extension using the MRC (Medical Research Council) score, the strength of the key grip (kg/F) as well as the autonomy of the patients using functional scores; Lamb (/100) and QIF (Quadriplegia Index of Function) (/100).

RESULTS

Sixteen upper limbs were included in the "one-stage" group and 29 in the "two-stage" group. The groups were comparable preoperatively. Elbow extension strength was 3.6/5 in the one-stage group versus 3.7/5, p=0.74. Grip strength was 1.8kg/F in the one-stage group versus 1.3kg/F, p=0.22. Regarding the functional scores, there was no statistically significant difference between the two groups for the Lamb score (p=0.46) and the QIF (p=0.42). There was no statistically significant difference in terms of the frequency of complications for the elbow (p=0.49) and for the hand (p=0.17). The total duration of the one-stage surgery plan averaged 7.5 months compared to 24.7 months for the two-stage plan, p<0.01. The mean follow-up for the one-stage group was 21 months versus 24 months for the two-stage group.

CONCLUSION

The results of both plans are similar and indicate that the "one-stage" plan is a reliable option. This all-in-one surgical option reduces postoperative follow-up and dropout rates for patients during the plan timeframe.

Spinal Cord Injury: Epidemiology, Spontaneous Recovery, and Hand Therapy for the Reconstructive Hand Surgeon

People with spinal cord injury (SCI) prioritize hand function above all else as a reconstructive goal, yet remain a markedly undertreated population by hand surgeons. This review article provides an overview of the epidemiology of SCI and the unmet clinical need of these patients. Further, this article outlines the natural history of SCI, including the expected spontaneous recovery over time and the expectations of hand function when treated with hand therapy alone. This review aims to equip reconstructive hand surgeons with a sound understanding of the basic principles of SCI and recovery and provide a rationale for when to intervene with surgery. In the last decade, this field has changed dramatically with the advent of reliable nerve transfers, making referral and surgical intervention time-sensitive. Therefore this review aims to highlight the expectations from hand therapy alone in this group, the urgent need for early referral to allow nerve transfer options to be viable, and the strategies for overcoming the barriers to these referrals. This offers the opportunity for surgeons to expand their tetraplegia practices while maximizing the considerable contributions to the hand function and quality of life of these patients.

A Mixed Methods Approach as a Channel to Interpret Outcomes Research and Lived Experience Enquiry of Upper Extremity Elective Surgery for Tetraplegia

Cervical spinal cord injury (SCI) causing tetraplegia is extremely disabling. In such circumstances, restoration of upper extremity (UE) function is considered the highest priority. The advent of early nerve transfer (NT) procedures, in addition to more traditional tendon transfers (TT), warranted in-depth consideration given the time-limited nature of NT procedures. Potential surgery candidates may not yet have come to terms with the permanence of their disability. A mixed methods convergent design was utilized for concurrent analysis of the Aotearoa/New Zealand upper limb registry data from the clinical assessments of all individuals considering UE surgery, regardless of their final decision. The International Classification of Functioning, Disability and Health (ICF) taxonomy guided data interpretation during the three-phased study series. It was the integration of the findings using the Stewart Model of care drawn from palliative health that enabled the interpretation of higher order messages. It is clear the clinical assessment and selection processes in use require reconsideration given the complexities individuals face following onset of SCI. We draw attention to the higher order cognitive demands placed on individuals, the requirement for SCI peer involvement in decision making and the need for acknowledgment of interdependence as a relational construct when living with tetraplegia.

Clinical Utility of Patient-Reported Outcome Measures Used for Tendon and Nerve Transfers for Tetraplegia in New Zealand

Purpose

This study determines the clinical utility of patient-reported outcome measures used to measure outcomes of upper extremity (UE) reconstructive procedures in individuals with tetraplegia. The patient-reported outcome measures are the Canadian Occupational Performance Measure, the Capabilities of Upper Extremity Questionnaire (CUE-Q), and the Personal Wellbeing Index.

Methods

Retrospective data of 43 individuals with spinal cord injury (SCI) levels C4-C7 tetraplegia, and American Spinal Injury Association Impairment Scale grades A-D who had upper limb reconstructive surgery were reviewed. Participants were grouped according to their SCI level and resultant surgical procedures into higher SCI severity and lower SCI severity groups.

Results

The mean age of participants was 26.3 years (SD 13.4; range 13-64 years). The higher-severity SCI group required elbow and hand reconstruction surgery, whereas the lower-severity group only required hand reconstruction surgery. Important differences in Canadian Occupational Performance Measure priorities were identified between the higher and lower SCI severity groups. Question redundancy was evident with the CUE-Q. The self-report Personal Wellbeing Index captures the possible impacts of improved UE function on an individual's perceived sense of personal wellbeing.

Conclusions

In this patient-reported outcome measure analysis, we found that the level of impairment influences patient priorities. Functional measures ought to consider UE impairment and personal wellbeing as a construct in this population, given the demands of surgery.

Exploring well-being services from the perspective of people with SCI: A scoping review of qualitative research

Objective

Well-being after spinal cord injury is affected by a range of factors, many of which are within the influence of rehabilitation services. Although improving well-being is a key aim of rehabilitation, the literature does not provide a clear path to service providers who seek to improve well-being. This study aimed to inform service design by identifying the experience and perspective of people with SCI about interventions targeting their well-being.

Method

The scoping review of qualitative literature used thematic analysis to identify and categorize themes related to service activities, valued aspects, limitations and perceived outcomes.

Results

Thirty-eight studies were selected, related to a range of service types. Most studies did not adopt a well-being conceptual framework to design and evaluate the services. People with SCI particularly valued being treated with dignity, positive expectations, increased autonomy and peer support. Improvements to well-being were reported, including many years post-SCI. However, people with SCI reported limited opportunities to engage in such services.

Conclusions

Rehabilitation services can improve well-being across the lifetime of people with SCI, but gaps in service provision are reported. The review identified valued aspects of services that may inform service design, including staff approach and positive expectations, having own skills and worth valued, peer support and interaction, autonomy in valued occupations, and long-term opportunities for gains.

The experience and perspective of people with spinal cord injury about well-being interventions: a systematic review of qualitative studies

PURPOSE

Promoting well-being is a key aim of rehabilitation. The intentional design of interventions to address well-being requires an understanding of the factors that affect this complex phenomenon. A growing body of qualitative literature has identified determinants that people with SCI report affect their well-being. It is unclear whether or how rehabilitation interventions can influence these well-being determinants. This study sought to explore the experience and perspective of people with SCI about interventions that target their well-being.

METHOD

Systematic search of seven databases. Deductive analysis to categorize findings related to well-being determinants, and further inductive coding to identify sub-themes, relationships and additional findings.

RESULTS

Twenty studies were selected, involving a wide range of interventions. Each intervention influenced a number of well-being determinants, which were inter-related. People with SCI reported improvements in both subjective and psychological well-being. However, well-being was not always well defined in the studies and people with SCI reported lack of priority for, and opportunity to engage in, well-being interventions in the current rehabilitation system.

CONCLUSIONS

Rehabilitation interventions can influence well-being determinants. These determinants form a useful framework for the intentional design of well-being interventions, which should be informed by a broad understanding of well-being.IMPLICATIONS FOR REHABILITATIONWell-being can be influenced by rehabilitation interventions, and a more explicit focus on well-being in intervention design and evaluation is recommended.Conceptual frameworks used to define and measure well-being should adopt a broad understanding of well-being.Well-being interventions should address the determinants identified by people with SCI (engaging in occupation, responsibility, values and perspectives, self-worth, self-continuity, relationships and the environment).People with SCI want a greater priority placed on well-being interventions, and more opportunities to engage in these interventions, especially in the community.

Upper-Extremity Reconstruction in Tetraplegia: A Critical Analysis Review

Management of tetraplegia should be individualized to a patient's particular deficiencies and functional goals. Surgical decision-making for upper-extremity reconstruction in patients with tetraplegia relies on a thorough physical examination to determine which nerves and muscles remain under volitional control with adequate strength for transfer. Peripheral nerve transfers, either in conjunction with or in place of traditional tendon transfers, enable providers to offer an expanded set of surgical options for patients with tetraplegia who are seeking upper-extremity reconstruction. All upper-extremity reconstructive efforts should be carefully considered with regard to their potential effects on the availability of future reconstructive efforts.

Hand Reconstruction in Children with Spinal Cord Injury

Comprehensive programs for children who sustain traumatic spinal cord injury should incorporate optimizing hand and upper extremity function along with the other traditional pillars of rehabilitation. Children's smaller anatomy, open growth plates, and future skeletal growth, combined with the age-related psychosocial impact of these injuries, require protocols suited to these age-related issues. There is a role for surgical reconstruction, as is the case for adults with traumatic tetraplegia, and surgical outcomes are equally beneficial and long lasting. Strict adherence to surgical indications, and surgical strategies and protocols that incorporate their age-related challenges, are the keys to successful management.

Regional estimates of cortical thickness in brain areas involved in control of surgically restored limb movement in patients with tetraplegia

Context/Objective: Spinal cord injury (SCI) causes atrophy of brain regions linked to motor function. We aimed to estimate cortical thickness in brain regions that control surgically restored limb movement in individuals with tetraplegia. Design: Cross-sectional study. Setting: Sahlgrenska University hospital, Gothenburg, Sweden. Participants: Six individuals with tetraplegia who had undergone surgical restoration of grip function by surgical transfer of one elbow flexor (brachioradialis), to the paralyzed thumb flexor (flexor pollicis longus). All subjects were males, with a SCI at the C6 or C7 level, and a mean age of 40 years (range = 31-48). The average number of years elapsed since the SCI was 13 (range = 6-26). Outcome measures: We used structural magnetic resonance imaging (MRI) to estimate the thickness of selected motor cortices and compared these measurements to those of six matched control subjects. The pinch grip control area was defined in a previous functional MRI study. Results: Compared to controls, the cortical thickness in the functionally defined pinch grip control area was not significantly reduced (P = 0.591), and thickness showed a non-significant but positive correlation with years since surgery in the individuals with tetraplegia. In contrast, the anatomically defined primary motor cortex as a whole exhibited substantial atrophy (P = 0.013), with a weak negative correlation with years since surgery. Conclusion: Individuals with tetraplegia do not seem to have reduced cortical thickness in brain regions involved in control of surgically restored limb movement. However, the studied sample is very small and further studies with larger samples are required to establish these findings.

Nothing to lose: a phenomenological study of upper limb nerve transfer surgery for individuals with tetraplegia

Purpose: For individuals with tetraplegia, regaining upper limb function forms the highest priority for improving quality of life. Use of nerve transfers to reconstruct upper limb function is increasing, however little is known about individual's decision to have and experience of the surgery and associated rehabilitation outcomes. This qualitative study aimed to understand the experience of surgery on the lives of individuals with tetraplegia 18 months post-surgery.Method: In-depth, semi-structured interviews were conducted with five purposively selected individuals who have undergone upper limb nerve transfers at a metropolitan health service, Melbourne, Australia, specializing in spinal cord injury rehabilitation. Collaizi's phenomenological framework guided data analysis, resulting in an essence statement describing the individuals' experience.Results: An essence statement comprising three themes; Deciding on Surgery, Facing Challenges: Surgery to Recovery and Evaluating Surgical Outcomes, was developed.Conclusion: The study suggests that for individuals with tetraplegia, hope to regain lost upper limb function forms a core consideration in the decision to have surgery. For clinicians supporting patient's decision, balancing hope with the realities of surgery is important. Even small changes in upper limb function had an important influence on participant's confidence in social situations through enhanced participation in a range of everyday activities.IMPLICATIONS FOR REHABILITATIONIn making a decision to have surgery, individuals with tetraplegia benefit from two way discussions with the healthcare team and others who have already undergone surgery.Healthcare teams need to help prepare individuals for the challenges of surgery including: expectations of pain, hospital stay, initial loss of independence and the time it may take to see re-innervation of target muscles and subsequent functional changes.Surgery should be routinely considered as individuals' report that even small changes in upper limb function positively increases participation in everyday tasks and confidence in social situations.When evaluating changes in upper limb function, patient-centered measures should be used.

Management of Spinal Cord Injury-Induced Upper Extremity Spasticity

Spasticity affects more than 80% of patients with spinal cord injury. Neural mechanisms and musculotendinous alterations lead to typical upper extremity features including shoulder adduction/internal rotation, forearm pronation, and elbow, wrist, and finger flexion. Long-standing spasticity may lead to soft tissue and joint contractures and further impairment of upper extremity function. Surgical management involves tendon lengthening, release, and transfer, as well as selective neurotomy, in an effort to reduce spastic muscle hypertonicity, restore balance, prevent further contracture, and improve posture and function. This article summarizes surgical strategies to improve function of the upper extremity in patients with tetraplegia.

Activity gains after upper limb surgery for spasticity in patients with spinal cord injury

Spasticity is a common and increasingly prevalent secondary complication of spinal cord injury. The aim of the study was to evaluate patient-experienced gains in prioritized activities after surgery to reduce the effects of spasticity in upper limbs in tetraplegia. The study includes evaluation of 30 operations for 27 patients performed on hypertonic tetraplegic hands during 2007-2015 using the Canadian Occupational Performance Measure. Activity performance increased at both 6 months and 12 months by a mean of 3.0 and 2.9 points, respectively. Satisfaction increased by 3.3 and 3.4, respectively. All types of activities improved, with wheelchair manoeuvring as one of the highest rated. The intervention increased prioritized activity performance and persisted at least 12 months after surgery. Patients with mild upper limb impairment showed greater improvement after surgery. After operation, patients were able to perform 71% of their prioritized activities, which they could not perform before. Patients' satisfaction with the performance was high.

Outcomes of reconstructive hand surgery in patients with tetraplegia and neuropathic pain

STUDY DESIGN

Retrospective cohort study OBJECTIVES: To evaluate the impact of preoperative neuropathic pain on outcome and postoperative compliance after grip reconstructive surgery in people with tetraplegia.

SETTING

Specialized tetraplegia upper-limb surgery center in Sweden.

METHODS

All patients who underwent grip reconstructive surgery and attended a 6 month follow up during January 2012 and May 2015 were included. Participants were divided into two groups, pain group and no pain group, based on preoperative rating of experienced pain on a visual analog scale. The main outcome measures were grip strength, grasp ability (Grasp and Release Test) and prioritized activity outcome (Canadian Occupational Performance Measure) together with compliance to the rehabilitation plan.

RESULTS

The study include 37 patients (86% of the cohort). Seventeen patients experienced preoperative pain (46%). There were no differences in outcome between the pain- and the no pain group regarding grip strength (5 vs. 4.6 kg), grip ability or activity performance and satisfaction (COPM improvement of 3.1 vs. 3.0 for performance and 3.6 for both groups in satisfaction). Both groups experienced improvements in all aspects and there were no differences in the ability to fulfill postoperative treatment.

CONCLUSIONS

Individuals with tetraplegia and preoperative neuropathic pain in the arm/hand improve after grip reconstructions in a similar way to those without pain. Patients with neuropathic pain therefore should be considered as surgery candidates to the same extent as those without pain.

Adaptive motor cortex plasticity following grip reconstruction in individuals with tetraplegia

Background:

Tendon transfer is a surgical technique for restoring upper limb motor control in patients with cervical spinal cord injuries (SCI), and offers a rare window into cortical neuroplasticity following regained arm and hand function.

Objective:

Here, we aimed to examine neuroplasticity mechanisms related to re-established voluntary motor control of thumb flexion following tendon transfer.

Methods:

We used functional Magnetic Resonance Imaging (fMRI) to test the hypothesis that restored limb control following tendon transfer is mediated by activation of that limb’s area of the primary motor cortex. We examined six individuals with tetraplegia who underwent right-sided surgical grip reconstruction at Sahlgrenska University Hospital, Sweden. All were right-handed males, with a SCI at the C6 or C7 level, and a mean age of 40 years (range = 31–48). The average number of years elapsed since the SCI was 13 (range = 6–26). Six right-handed gender- and age-matched control subjects were included (mean age 39 years, range = 29–46). Restoration of active thumb flexion in patients was achieved by surgical transfer of one of the functioning elbow flexors (brachioradialis), to the paralyzed thumb flexor (flexor pollicis longus). We studied fMRI responses to isometric right-sided elbow flexion and key pinch, and examined the cortical representations within the left hemisphere somatomotor cortex a minimum of one year after surgery.

Results:

Cortical activations elicited by elbow flexion did not differ in topography between patients and control participants. However, in contrast to control participants, patients’ cortical thumb flexion activations were not topographically distinct from their elbow flexion activations.

Conclusion:

This result speaks against a topographic reorganization in which the thumb region regains thumb control following surgical tendon transfer. Instead, our findings suggest a neuroplastic mechanism in which motor cortex resources previously dedicated to elbow flexion adapt to control the thumb.

Decision-Making About Upper Limb Tendon Transfer Surgery by People With Tetraplegia for More Than 10 Years

OBJECTIVES

To quantify time from spinal cord injury to upper limb reconstructive surgery for individuals with tetraplegia; to explore influences on decision-making about surgery for persons with long-standing (>10y) tetraplegia; and to determine the applicability of our previously developed conceptual framework that described the decision-making processes for people with tetraplegia of <5 years.

DESIGN

Quantitative-qualitative mixed-methods study.

SETTING

Community based in New Zealand.

PARTICIPANTS

People (N=9) living with tetraplegia for >10 years.

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURES

An audit of time frames between injury, assessment, and surgery for people with tetraplegia was undertaken. Interviews of people with tetraplegia were analyzed using constructivist grounded theory.

RESULTS

Sixty-two percent of people with tetraplegia assessed for surgery had upper limb reconstructive surgery. Most were assessed within the first 3 years of spinal cord injury. Over half had surgery within 4 years after injury; however, 20% waited >10 years. Changes in prioritized activities, and the identification of tasks possible with surgery, were influential in the decision-making process. Participants were aware of surgery, but required a reoffer from health professionals before proceeding. The influence of peers was prominent in reinforcing the improvement in prioritized activities possible after surgery.

CONCLUSIONS

Findings confirmed that the previously developed conceptual framework for decision-making about upper limb reconstructive surgery was applicable for people with tetraplegia of >10 years. Similarities were seen in the influence of goals and priorities (although the nature of these might change) and information from peers (although this influence was greater for those injured longer). Repeat offers for surgery were required to allow for changes in circumstances over time.

Satisfaction with upper limb reconstructive surgery in individuals with tetraplegia: the development and reliability of a Swedish self-reported satisfaction questionnaire

Study design:

A questionnaire-based survey.

Objectives:

To assess satisfaction after upper limb reconstructive surgery in individuals with tetraplegia and to determine the reliability of a Swedish satisfaction questionnaire.

Setting:

A center for advanced reconstruction of extremities, Gothenburg, Sweden.

Methods:

Seventy-eight individuals with tetraplegia were invited to participate in the survey assessing satisfaction with the result of surgery across various domains. Measures of reliability included stability and internal consistency of domains consisting questions regarding global satisfaction, activities and occupation/schooling.

Results:

Fifty-eight individuals (76%) participated, among whom 47 (82%) completed the questionnaire twice for repeatability assessment. The responses in the domains relating to global satisfaction, activities and occupation/schooling were positive in 83%, 72% and 31% of participants, respectively. Ninety-five percent felt they had benefited from the surgery, and 86% felt that the surgery had made a positive impact on their life. The psychometric testing indicated that the questionnaire yields scores that are reliable by both test–retest and internal consistency, with the exception of the domain occupation/schooling that had a high prevalence of missing and neutral responses and seemingly represents separate and distinct entities.

Conclusion:

Surgical rehabilitation of the upper limb in tetraplegia is highly beneficial and rewarding from a patient perspective, leading to satisfactory gains in activities of daily living as well as enhanced quality of life. The questionnaire is a reliable instrument for measuring satisfaction after surgery. However, occupationally and educationally related aspects of the surgical outcome should constitute separate domains, and further modifications of the questionnaire are thus recommended.

Nerve Transfers to Restore Upper Extremity Function in Cervical Spinal Cord Injury: Update and Preliminary Outcomes

BACKGROUND

Cervical spinal cord injury can result in profound loss of upper extremity function. Recent interest in the use of nerve transfers to restore volitional control is an exciting development in the care of these complex patients. In this article, the authors review preliminary results of nerve transfers in spinal cord injury.

METHODS

Review of the literature and the authors' cases series of 13 operations in nine spinal cord injury nerve transfer recipients was performed. Representative cases were reviewed to explore critical concepts and preliminary outcomes.

RESULTS

The nerve transfers used expendable donors (e.g., teres minor, deltoid, supinator, and brachialis) innervated above the level of the spinal cord injury to restore volitional control of missing function such as elbow extension, wrist extension, and/or hand function (posterior interosseous nerve or anterior interosseous nerve/finger flexors reinnervated). Results from the literature and the authors' patients (after a mean postsurgical follow-up of 12 months) indicate gains in function as assessed by both manual muscle testing and patients' self-reported outcomes measures.

CONCLUSIONS

Nerve transfers can provide an alternative and consistent means of reestablishing volitional control of upper extremity function in people with cervical level spinal cord injury. Early outcomes provide evidence of substantial improvements in self-reported function despite relatively subtle objective gains in isolated muscle strength. Further work to investigate the optimal timing and combination of nerve transfer operations, the combination of these with traditional treatments (tendon transfer and functional electrical stimulation), and measurement of outcomes is imperative for determining the precise role of these operations.

Tetraplegia Management Update

Tetraplegia is a profound impairment of mobility manifesting as a paralysis of all 4 extremities owing to cervical spinal cord injury. The purpose of this article is to provide an update and analyze current management, treatment options, and outcomes of surgical reconstruction of arm and hand function. Surgical restoration of elbow and wrist extension or handgrip has tremendous potential to improve autonomy, mobility, and critical abilities, for example, eating, personal care, and self-catheterization and productive work in at least 70% of tetraplegic patients. Tendon and nerve transfers, tenodeses, and joint stabilizations reliably enable improved arm and hand usability, reduce muscle imbalance and pain in spasticity, and prevent joint contractures. One-stage combined procedures have proven considerable advantages over traditional multistage approaches. Immediate activation of transferred muscles reduces the risk of adhesions, facilitates relearning, avoids adverse effects of immobilization, and enhances functional recovery. Transfer of axillary, musculocutaneous, and radial nerve fascicles from above the spinal cord injury are effective and promising options to enhance motor outcome and sensory protection, especially in groups with limited resources. Improved communication between medical disciplines, therapists, patients, and their relatives should help that more individuals can benefit from these advances and could empower many thousands tetraplegic individuals "to take life into their own hands" and live more independently.
