Abstract
Latin dance involves fundamental walking steps, integral to the dance process. While resembling daily walking, Latin dance demands higher balance levels, necessitating body adjustments by dancers. These adaptations affect dancers' gait biomechanics, prompting our study on gait differences between Latin dancers (LDs) and non-dancers (NDs). We enlisted 21 female Latin dancers and 21 subjects based on specific criteria. Participants executed walking tasks, with an independent sample t-test for 1-dimensional statistical parameter mapping (SPM 1d) analyzing stance phase variations between LDs and NDs. Notably, significant differences in ankle and hip external rotation were evident during the 16.43-29.47% (p = 0.015) and 86.35-100% (p = 0.014) stance phase. Moreover, pronounced distinctions in rectus Achilles tendon force (ATF) (12.83-13.10%, p = 0.049; 15.89-80.19%, p < 0.001) and Patellofemoral joint contact force (PTF) (15.85-18.31%, p = 0.039; 21.14-24.71%, p = 0.030) during stance were noted between LDs (Latin dancers) and NDs (Non-dancers). The study revealed dancers' enhanced balance attributed to external ankle rotation for dance stability, coupled with augmented Achilles tendon and patellofemoral joint strength from prolonged practice. Moreover, integrating suitable Latin dance into rehabilitation may benefit those with internal rotation gait issues.

Evaluation methods to assess the efficacy of equinovarus foot surgery on the gait of post-stroke hemiplegic patients: A literature review. Front Neurol 2022; 13:1042667.

Abstract
IntroductionThe aim of this study was to realize a systematic review of the different ways, both clinical and instrumental, used to evaluate the effects of the surgical correction of an equinovarus foot (EVF) deformity in post-stroke patients.MethodsA systematic search of full-length articles published from 1965 to June 2021 was performed in PubMed, Embase, CINAHL, Cochrane, and CIRRIE. The identified studies were analyzed to determine and to evaluate the outcomes, the clinical criteria, and the ways used to analyze the impact of surgery on gait pattern, instrumental, or not.ResultsA total of 33 studies were included. The lack of methodological quality of the studies and their heterogeneity did not allow for a valid meta-analysis. In all, 17 of the 33 studies involved exclusively stroke patients. Ten of the 33 studies (30%) evaluated only neurotomies, one study (3%) evaluated only tendon lengthening procedures, 19 studies (58%) evaluated tendon transfer procedures, and only two studies (6%) evaluated the combination of tendon and neurological procedures. Instrumental gait analysis was performed in only 11 studies (33%), and only six studies (18%) combined it with clinical and functional analyses. Clinical results show that surgical procedures are safe and effective. A wide variety of different scales have been used, most of which have already been validated in other indications.DiscussionNeuro-orthopedic surgery for post-stroke EVF is becoming better defined. However, the method of outcome assessment is not yet well established. The complexity in the evaluation of the gait of patients with EVF, and therefore the analysis of the effectiveness of the surgical management performed, requires the integration of a patient-centered functional dimension, and a reliable and reproducible quantified gait analysis, which is routinely usable clinically if possible.

Respective Contributions of Instrumented 3D Gait Analysis Data and Tibial Motor Nerve Block on Presurgical Spastic Equinus Foot Assessment: A Retrospective Study of 40 Adults. Front Neurol 2022; 13:862644.

Abstract
Spastic equinus foot is a common deformity in neurologic patients who compromise walking ability. It is related to the imbalance between weak dorsiflexion and overactive plantar flexor muscles. To achieve the best functional results after surgical management, the challenge is to identify the relevant components involved in the deformity using several methods, namely, examination in the supine position, motor nerve blocks allowing transient anesthesia of suspected overactive muscles, and kinematic and electromyographic data collected during an instrumented 3D gait analysis. The procedure is not standardized; its use varies from one team to another. Access to gait analysis laboratories is limited, and some teams do not perform motor nerve blocks. When both examinations are available, instrumental data from the instrumented 3D gait analysis can be used to specify muscle targets for motor blocks, but data collected from both examinations are sometimes considered redundant. This retrospective cohort analysis compared examination in the supine position, temporary motor nerve blocks, and instrumented 3D gait analysis data in 40 adults after brain or spinal cord injuries. Clinical data collected before motor nerve block was not associated with instrumental data to assess calf muscle's overactivity and tibialis anterior function. Improvement of ankle dorsiflexion in the swing phase after tibial motor nerve block was associated with soleus spastic co-contraction during this phase corroborating its involvement in ankle dorsiflexion defects. This study showed the relevance of tibial motor nerve block to remove spastic calf dystonia and facilitate the assessment of calf contracture. It also underlined the need for complementary and specific analyses of the tibialis anterior abnormal activation pattern after motor nerve block to confirm or deny their pathological nature.

[PMID: 34953669 DOI: 10.1053/j.jfas.2021.11.012] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/12/2021] [Revised: 11/18/2021] [Accepted: 11/20/2021] [Indexed: 02/03/2023]
Abstract
Neuro-orthopedic surgery is an alternative to the conservative treatment of spastic equinovarus foot (SEF) in adults. The objective of the present narrative review was to summarize current practice with regard to patient assessment, the choice of treatment, the various neuro-orthopedic procedures, and the latter's outcomes. We searched literature databases (MEDLINE, EMBASE, Cochrane) for original articles or opinion papers on surgical treatment of spastic equinovarus foot in adults. Neuro-orthopedic approaches require a careful analysis of the patient's and/or his/her caregiver needs and thus relevant treatment goals. Surgical planning requires detailed knowledge of impairments involved in the spastic equinovarus foot deformity based on a careful clinical examination and additional information from diagnostic nerve blocks and/or a quantitative gait analysis. Procedures mainly target nerves (neurotomy) and tendons (lengthening, transfer, tenotomy). These procedures reduce impairments (spasticity, range of motion, and foot position), improve gait and walking function, but their impact on participation and personalized treatment goals remains to be demonstrated. Neuro-orthopedic surgery is an effective treatment option for spastic equinovarus foot in adults. However, practice is still very heterogeneous and there is no consensus on the medical strategies to be applied before, during and after surgery (particularly the type of anesthesia, the need for immobilization, rehabilitation procedures).

Abstract
BACKGROUND In patients with chronic Achilles tendon disorders, Achilles tendon debridement can be supplemented with a tendon transfer, with the flexor hallucis longus tendon (FHL) transfer representing the most common used technique. Our study describes clinical and functional results of patients treated with flexor digitorum longus (FDL) tendon transfer in the treatment of patients with chronic Achilles tendon disorders. METHODS Retrospective study of prospectively collected data of thirteen patients (15 feet) that underwent FDL tendon transfer as part of the treatment of chronic Achilles tendon disorders. Preoperative and postoperative assessment included visual analogue score (VAS) for pain, SF-36 survey and lower extremity functional scale (LEFS). The average follow-up was 26.4 (range, 14-56) months. Patients were also assessed for ability to perform single leg heel rise test, muscle power for plantar flexion of the lesser toes, surgical scar condition and associated complications. RESULTS At final follow-up, we found significant postoperative improvement in VAS score (6.6 ± 2.99 vs 1.06 ± 1.43; p < .0001), SF-36 physical component summary (PCS) (28.20 ± 10.71 vs 45.04 ± 11.19; p < .0001) and LEFS (36.13 ± 20.49 vs 58.73 ± 18.19; p < .0001). Twelve patients (92%) could perform a single leg heel rise test in the operated extremity, although there was significant difference when comparing operated and uninvolved sides (4.86 ± 3.36 cm vs 7.18 ± 3.40 cm; p = .0002). One patient reported weakness for plantar flexion of the lesser toes, without balance or gait disturbances. Two patients (2 feet, 13.3%) had superficial infections and one patient (one foot, 6.6%) needed operative debridement for a deep infection. CONCLUSIONS FDL tendon transfer represent an operative alternative in the treatment of chronic Achilles tendon disorders. Our study showed good clinical outcomes with low complications and donor site morbidity. LEVEL OF EVIDENCE Observational study, case series - level IV.

Abstract
Lower limb dysfunction associated with upper motor neuron syndrome can be complex due to interaction of muscle overactivity, weakness, impaired motor control, and contracture. Treatment should be goal-directed and address the patient's passive and active functional impairments in addition to their symptoms. Therefore, a comprehensive, multidisciplinary team approach tailored to each patient's unique needs and functional goals is warranted. This article reviews the evaluation and management of issues related to lower limb muscle overactivity and how this approach was applied to 3 challenging cases.

Abstract
Upper motor neuron disease or injury can lead to muscle spasticity or nonfunction throughout the body. Imbalance in muscle forces predisposes patients to development of functional deficiencies, contractures, pain, and poor hygiene. The approach to neuro-orthopaedic patients is by necessity multidisciplinary, because a variety of nonsurgical and surgical options are available. In evaluating each patient, surgeons must consider the extent and quality of any deformity, potential for improvement in function, the ability to alleviate pain, and potential for improvement in hygiene and cosmesis. Surgical techniques include tendon lengthenings, releases, transfers, osteotomies, and bony fusions.

Abstract
Spastic foot and ankle deformities can occur from various causes and have profound effects on individuals and society. Presentations can vary clinically and a thorough clinical evaluation, potentially with a dynamic electromyogram, is essential to selecting the most appropriate treatment. Nonoperative treatments, such as orthotics, casting, oral medications, and nerve blocks, can be effective but surgery is indicated if they are no longer effective. Of the various operative procedures to treat this condition, split anterior tibialis tendon transfer and tendo Achilles lengthening are the most commonly performed. Multiple surgical options have been shown to be effective.

Abstract
Tendon transfer surgery plays a central role in the treatment of pediatric foot deformities. Tendon transfers are essential for balancing in neurogenic deformities but also important for the treatment of congenital or idiopathic deformities. Furthermore tendon transfer represents an important management tool for revision surgery of failed treatment in foot deformities. Complications and pit-falls which can potentially lead to failure may occur during the indications and planning of the transfer as well as during the surgery. The identification and analysis of possible pitfalls and complications as well as their management is the central issue of this article. Knowledge about possible problems and their management are essential for successful treatment of pediatric foot deformities.

Abstract
AIMS Orthopaedic care of adults with cerebral palsy (CP) has not been well documented in orthopaedic literature. This paper focuses on some of the common problems which present themselves when adults with CP seek orthopaedic intervention. In particular, we review the most common orthopaedic issues which present to the Penn Neuro-Orthopaedics Program. METHOD A formal review of consecutive surgeries performed by the senior author on adults with CP was previously conducted. This paper focuses on the health delivery care for the adult with orthopaedic problems related to cerebral palsy. Ninety-two percent of these patients required lower extremity surgery. Forty percent had procedures performed on the upper extremities. RESULTS The majority of problems seen in the Penn Neuro-Orthopaedics Program are associated with the residuals of childhood issues, particularly deformities associated with contractures. Patients are also referred for treatment of acquired musculoskeletal problems such as degenerative arthritis of the hip or knee. A combination of problems contribute most frequently to foot deformities and pain with weight-bearing, shoewear or both, most often due to equinovarus. The surgical correction of this is most often facilitated through a split anterior tibial tendon transfer. Posterior tibial transfers are rarely indicated. Residual equinus deformities contribute to a pes planus deformity. The split anterior tibial tendon transfer is usually combined with gastrocnemius-soleus recession and plantar release. Transfer of the flexor digitorum longus to the os calcis is done to augment the plantar flexor power. Rigid pes planus deformity is treated with a triple arthrodesis. Resolution of deformity allows for a good base for standing, improved ability to tolerate shoewear, and/or braces. Other recurrent or unresolved issues involve hip and knee contractures. Issues of lever arm dysfunction create problems with mechanical inefficiency. Upper extremity intervention is principally to correct contractures. Internal rotation and adductor tightness at the shoulder makes for difficult underarm hygiene and predispose a patient to a spiral fracture of the humerus. A tight flexor, pronation pattern is frequently noted through the elbow and forearm with further flexion contractures through the wrist and fingers. Lengthenings are more frequently performed than tendon transfers in the upper extremity. Arthrodesis of the wrist or on rare occasions of the metacarpal-phalangeal joints supplement the lengthenings when needed. CONCLUSIONS The Penn Neuro-Orthopaedics Program has successfully treated adults with both residual and acquired musculoskeletal deformities. These deformities become more critical when combined with degenerative changes, a relative increase in body mass, fatigue, and weakness associated with the aging process.

Abstract
BACKGROUND Spastic equinovarus (SEV) is the most common leg deformity after cerebrovascular accident (CVA). This study reviewed functional outcomes after surgical correction of SEV in a cohort of hemiplegic, post-CVA patients. METHODS Sixty-four consecutive post-CVA SEV patients who underwent surgical correction from January 2003 to January 2006 were included. Data parameters included age, sex, duration since CVA, preoperative orthotic and ambulatory requirements, and Viosca ambulation scores. There were 45 females and 19 males. Average age was 54 (range, 24 to 74) years. Average duration from CVA to surgery was 66 (range, 17 to 523) months. Mean followup was 50.1 (range, 12 to 168) weeks. Final outcomes included status of correction, bracing needs, use of assistive devices, and Viosca score. Univariate and multivariate statistical analyses were performed to determine if age, sex, and time from CVA to surgery affected outcome. RESULTS All feet were corrected to plantigrade position. Of the 48 patients who used orthoses preoperatively, 27 (56%) continued use while 11 (44%) were brace-free postoperatively. Of the 23 patients that used an ambulatory assistive device preoperatively, 12 (52%) continued use and 11 (47.8%) were free of assistive devices postoperatively. Median Viosca score improved from two (Independent Household Ambulation) to three (Independent Neighborhood Ambulation) (p < 0.001). There was no statistical association between age, sex, CVA chronicity and outcome parameters. CONCLUSION These results indicate that surgical correction of SEV is effective in post-CVA patients. Patients demonstrated improvement in ambulation score regardless of age, sex, or duration from CVA to surgery.

Abstract
OBJECTIVE In patients with hemiplegic stroke, equinovarus foot is one of the most frequent deformities. Outcome evidence for surgical correction of equinovarus foot is scarce, and results are usually assessed only clinically. Moreover, concerns about possible loss of function after elongation of the plantar flexor muscles are still at issue. The objective of this study was to verify if surgical correction of equinovarus foot can improve gait speed and function. DESIGN We used a retrospective, nonrandomized design. One hundred seventy-seven chronic hemiplegic patients who underwent surgical correction of equinovarus foot were evaluated before and 1 yr after surgery. Outcome measures were walking handicap score, temporal-spatial parameters, gait kinematics and kinetics, and paretic propulsion. RESULTS After surgery, walking handicap and temporal-spatial parameters significantly improved, as did ankle kinematic data and gait kinetic data. Patients' gait at follow-up was faster, with a more normal base of support and with better foot advancement. Paretic propulsion increased significantly after surgery, even if ankle power at push-off was reduced. We also observed a low complication rate. CONCLUSIONS Surgical correction of equinovarus foot deformity in patients with stroke is a safe and effective procedure. Even if the power generation at the ankle decreased, overall gait function and parameters improved after surgery.

Abstract
Equinovarus of the foot is the most common lower extremity deformity following traumatic brain injury. We evaluated outcomes of the split anterior tibialis tendon transfer (SPLATT) for correction of equinovarus in 47 patients with hemiplegic traumatic brain injury and specifically studied differences in outcomes with two tendon fixation techniques. Seventeen patients constituting Group I underwent fixation with one technique and 30 constituting Group II had another technique. Patients in both groups had appropriate procedures based on dynamic electromyography and gait analyses. Both groups were demographically comparable. All 47 feet were corrected to plantigrade position. Thirty-six of 47 patients became brace-free at final followup. There was a notable decrease in the use of ambulatory aids and ambulatory status improved in both groups. There were three fixation-related complications in Group I and none in Group II. Surgical correction of the spastic equinovarus with SPLATT, in the appropriate patient, with or without associated tendon procedures helps to achieve and maintain correction, improves the ambulatory status of the patient, and eliminates the need for bracing in as much as 77% of patients. We recommend the Group II construct owing to the considerably lower complication rate.
