Robotic assisted and exoskeleton gait training effect in mental health and fatigue of multiple sclerosis patients. A systematic review and a meta-analysis.

PURPOSE: Robotic and Exoskeleton Assisted Gait Training (REAGT) has become the mainstream gait training module. Studies are investigating the psychosocial effects of REAGT mostly as secondary outcomes. Our systematic review and meta-analysis aims to investigate the effects of REAGT in MS patients' mental health and fatigue. MATERIALS AND METHODS: We searched the electronic databases (Scopus, PubMed, Pedro, Cochrane Trials, Dare) for RCT studies fulfilling our inclusion criteria. A meta-analysis of available assessment tools was conducted calculating the summary mean differences in two different timepoints, before and after the intervention using random-effects models. RESULTS: The systematic search of the electronic databases identified 302 studies. Seven RCT studies were considered eligible for data extraction and meta-analysis, according to our eligibility criteria. We were able to obtain adequate data to proceed with a quantitative synthesis for QoL SF36-MC (Mental Component), QoL SF-36 mental and psychosocial subscales, Multiple Sclerosis Quality of Life-54-Mental Health Composite (MSQoL-54-MHC), Patient's Health Questionnaire (PHQ-9) and Fatigue Severity Scale (FSS). CONCLUSIONS: Overall, REAGT seems to have a positive effect to Quality of Life, especially in MS patients' perspective of General and Mental Health and a slight positive effect in depression as measured by PHQ-9.Implications for rehabilitationMultiple Sclerosis (MS) decreases physical and non-physical aspects of patients' quality of life perspective.Rehabilitation strategy must take into consideration the non-physical effects of a training intervention.Robotic and Exoskeleton Gait Training has a positive effect in MS patients' non-physical quality of life and a slight positive effect in depression.

The experience of gender in spousal caregiving: A phenomenological psychological study (Greece).

PURPOSE/OBJECTIVE: To explore how spousal caregivers of older people undergoing rehabilitation experience gender within the Greek community. RESEARCH METHOD/DESIGN: A psychological phenomenological design and analysis were used to illuminate the unique meanings 11 spousal caregivers attribute to their experience of gender by gathering qualitative data via interviews. RESULTS: The data provided an insight into the structure of the experience of gender for the spousal caregivers as a normative diachronic identity in a succession of phases: normative constitution, alienation, and reparation. CONCLUSIONS/IMPLICATIONS: The findings highlight the influence of gender stereotypes on spousal caregivers' self-concept, agency, caregiving evaluations, and practices, emphasizing the importance of adopting an intersectional perspective in future research and interventions, considering various factors such as ethnicity, gender, sexuality, age, power dynamics, and cultural norms. Spousal caregivers experience alienation on entering the caregiving journey, with gender-related vulnerabilities affecting their psychological well-being. Addressing these vulnerabilities can improve caregivers' mental health and foster effective coping strategies. The study emphasizes the moral aspect of caregiving, highlighting the relationship between a sense of obligation, feelings of guilt, gender norms, and motivations calling for challenging self-sacrificial morals and societal norms associated with them to empower caregivers to prioritize their well-being while maintaining their caregiving motivations. This shift in perspective can lead to a more positive and fulfilling caregiving experience. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

Older adults' lived experiences of physical rehabilitation for acquired brain injury and their perceptions of well-being: A qualitative phenomenological study.

AIM: To explore the experiences of older adults (65+) living with acquired brain injury regarding their sense of well-being during physical rehabilitation within the Greek Healthcare System. BACKGROUND: With the increasing ageing population and the life-changing effects of acquired brain injury, there is a need to focus on care for older people and their potential to live well. Rehabilitation systems deserve greater attention, especially in improving the well-being of those who are using them. DESIGN: A qualitative study design with a hermeneutic phenomenological approach was used. METHODS: Fourteen older adults living with acquired brain injury and undergoing physical rehabilitation in Greece were purposively sampled. Semi-structured interviews were conducted to collect data and were thematically analysed using van Manen's and Clarke and Braun's methods. The COREQ checklist was followed. RESULTS: Four themes emerged from the analysis: (1) Challenges of new life situation, (2) Seeking emotional and practical support through social interaction, (3) Identifying contextual processes of rehabilitation, (4) Realising the new self. CONCLUSIONS: The subjective experiences, intersubjective relations and contextual conditions influence the sense of well-being among older adults living with acquired brain injury, thus impacting the realisation of their new self. The study makes the notion of well-being a more tangible concept by relating it to the degree of adaptation to the new situation and the potential for older adults to create a future whilst living with acquired brain injury. RELEVANCE FOR CLINICAL PRACTICE: Identifying the factors that impact older adults' sense of well-being during rehabilitation can guide healthcare professionals in enhancing the quality of care offered and providing more dignified and humanising care. PATIENT OR PUBLIC CONTRIBUTION: Older adults living with acquired brain injury were involved in the study as participants providing the research data.

Rotationplasty outcomes assessed by gait analysis following resection of lower extremity bone neoplasms.

Aims: The standard of surgical treatment for lower limb neoplasms had been characterized by highly interventional techniques, leading to severe kinetic impairment of the patients and incidences of phantom pain. Rotationplasty had arisen as a potent limb salvage treatment option for young cancer patients with lower limb bone tumours, but its impact on the gait through comparative studies still remains unclear several years after the introduction of the procedure. The aim of this study is to assess the effect of rotationplasty on gait parameters measured by gait analysis compared to healthy individuals. Methods: The MEDLINE, Scopus, and Cochrane databases were systematically searched without time restriction until 10 January 2022 for eligible studies. Gait parameters measured by gait analysis were the outcomes of interest. Results: Three studies were eligible for analyses. Compared to healthy individuals, rotationplasty significantly decreased gait velocity (-1.45 cm/sec; 95% confidence interval (CI) -1.98 to -0.93; p < 0.001), stride length (-1.20 cm; 95% CI -2.31 to -0.09; p < 0.001), cadence (-0.83 stride/min; 95% (CI -1.29 to -0.36; p < 0.001), and non-significantly increased cycle time (0.54 sec; 95% CI -0.42 to 1.51; p = 0.184). Conclusion: Rotationplasty is a valid option for the management of lower limb bone tumours in young cancer patients. Larger studies, with high patient accrual, refined surgical techniques, and well planned rehabilitation strategies, are required to further improve the reported outcomes of this procedure.

The efficacy of Equine Assisted Therapy intervention in gross motor function, performance, and spasticity in children with Cerebral Palsy.

Purpose: To evaluate the efficacy of Equine Assisted Therapy in children with Cerebral Palsy, in terms of gross motor function, performance, and spasticity as well as whether this improvement can be maintained for 2 months after the end of the intervention. Methods: Children with Cerebral Palsy participated in this prospective cohort study. The study lasted for 28 weeks, of which the equine assisted therapy lasted 12 weeks taking place once a week for 30 min. Repeated measures within the subject design were used for the evaluation of each child's physical performance and mental capacity consisting of six measurements: Gross Motor Function Measure-88 (GMFM-88), Gross Motor Performance Measure (GMPM), Gross Motor Function Classification System (GMFCS), Modified Ashworth Scale (MAS) and Wechsler Intelligence Scale for Children (WISC III). Results: Statistically significant improvements were achieved for 31 children in Gross Motor Function Measure and all its subcategories (p < 0.005), also in total Gross Motor Performance Measure and all subcategories (p < 0.005). These Gross Motor Function Measure results remained consistent for 2 months after the last session of the intervention. Regarding spasticity, although an improving trend was seen, this was not found to be statistically significant. Conclusion and implications: Equine Assisted Therapy improves motor ability (qualitatively and quantitatively) in children with Cerebral Palsy, with clinical significance in gross motor function.

Role of Kinesiotherapy in the Prevention of Heterotopic Ossification: A Systematic Review.

OBJECTIVE: The role of kinesiotherapy in heterotopic ossification remains unclear. The goal of this study was to revisit the literature on the preventive role of kinesiotherapy against heterotopic ossification formation and maturation. DESIGN: A systematic review was performed in MEDLINE, OVID, Scopus, and Cochrane databases. RESULTS: A high-quality clinical trial is missing from the literature. Of 9617 studies primarily identified, nine studies offered the proper data and were included. They infer that satisfactory results on neurogenic heterotopic ossification prevention were achieved with passive exercises, including continuous passive motion, that were initiated early and at a painless range of motion. On the contrary, for elbow posttraumatic heterotopic ossification and major joints burn-associated heterotopic ossification, active range of motion is indicated as early as possible. CONCLUSIONS: Because of the very low quality of the studies included in this review, firm conclusions cannot be drawn about the effectiveness of kinesiotherapy. Nevertheless, it is recommended that controlled passive range of motion exercises (especially continuous passive motion) be applied early and pain-free especially in the neurogenic heterotopic ossification patients while active range of motion in painless limits is beneficial in the heterotopic ossification prevention of traumatic elbows or burn joints.

Prosthetic reconstruction following resection of lower extremity bone neoplasms: A systematic review and meta-analysis.

Prosthetic reconstructive procedures have become the mainstay in contemporary surgical treatment following resection of extremity bone neoplasms. Given that these patients are of young age most of the time, achievement of robust functional outcomes is of paramount importance. The aim of this study is to assess the impact of this procedure on the gait parameters of cancer patients compared to healthy individuals. The Medline, Scopus and Cochrane databases were systematically searched until January 2022 for eligible studies. Gait parameters measured by gait analysis after prosthetic reconstruction were the outcomes of interest. Eight cohort studies were included in our analysis. From these, seven studied prosthetic reconstruction of the knee (distal femur or proximal tibia) and only one exclusively studied prostetic reconstructions of the proximal femur. Compared to healthy individuals a significant decrease was evident in gait velocity (-0.16 m/sec, 95 %CI: -0.23 to -0.09, p-value < 0.001), in stride length (-6.07 %height, 95 %CI: -9,36 to -2.78, p-value < 0.001), in cadence (-3.96 stride/min, 95 %CI: -5.41 to -2.51, p-value < 0.001) and significant increase in cycle time (0.10 s, 95 %CI: 0.03 to 0.17, p-value = 0.005). Prosthetic reconstruction following lower limb tumor resection significantly affects the gait of patients. This knowledge can be utilized for further refinement of surgical techniques, rehabilitation strategies and follow-up programming.

A systematic review of the qualitative literature on older individuals' experiences of care and well-being during physical rehabilitation for acquired brain injury.

AIMS: To acquire an in-depth understanding of how older individuals diagnosed with acquired brain injury (ABI) experience their well-being and care when undergoing physical rehabilitation. DESIGN: Systematic literature review. DATA SOURCES: The electronic databases of PubMed, CINAHL, APA PsycInfo, ASSIA and SCOPUS were searched from 2005 to 2020. Extensive reference checking was also conducted. REVIEW METHODS: A systematic review was conducted following PRISMA guidelines, including predominantly qualitative studies. Studies' quality was appraised using the critical apraisal skills programme (CASP) tool. RESULTS: Seventeen studies met the inclusion criteria. Following methods of thematic synthesis, four overarching interpretive themes were identified: (a) Rehabilitation processes and their impact on older individuals' well-being; (b) Identity and embodiment concerns of older individuals during rehabilitation; (c) Institutional factors affecting older individuals' care and well-being experiences; and (d) Older individuals' participation in creative activities as part of rehabilitation. CONCLUSION: Organizational and structural care deficiencies as well as health disparities can adversely impact older individuals' autonomous decision-making and goal-setting potentials. The discrepancy between older individuals' expectations and the reality of returning home along with the illusionary wish to return to a perceived normality, can further negatively affect older individuals' sense of well-being. Constructive communication, emotional support, family involvement in rehabilitation and creating a stimulating, enriching social environment can humanize and facilitate older individuals' adjustment to their new reality following ABI. IMPACT: There is a lack of qualitative research on older individuals' ABI rehabilitation experiences, especially traumatic brain injury incidents. Further study should consider patients' concerns over their involvement in decision-making and goal setting about their care. Overall, this review reveals the need to examine further the significance of humanizing care and the factors that affect older individuals' sense of well-being.

The effectiveness of botulinum toxin on spasticity and gait of hemiplegic patients after stroke: A systematic review and meta-analysis.

The aim of the study is to evaluate the evidence supporting the efficacy of botulinum toxin type A (BTA) injections in lower limb of hemiplegic patients, after stroke or cerebrovascular accident, and their gait analysis. This study included: randomized controlled trials (RCTs), non-randomized or controlled clinical trials (CCTs) or cluster trials, clinical trials of various phases (I-III), interrupted time series (ITS) studies with at least three data points before and after the intervention, controlled before and after (CBA) studies, prospective and retrospective comparative cohort studies, case-control and multicentred studies. The patients included in these studies had similar characteristics: age over 18 years, history of stroke and following hemiplegia, minimum modified Ashworth scale (MAS) score of 2 and duration since stroke over 6 months. The number of studies included in this review was 21. A meta-analysis was performed on a fraction of them depending on the reported index and the methodology as reported in detail in the results section. MAS score, following BTA injections, was significantly improved (Hedges' g: -1.17; 95% CI: -1.66, 0.67; p < 0.001). The same applied for the 10 Meter Walk Test (MWT) (-0.35; 95% CI: -0.68, -0.02; p = 0.016). The gait velocity showed improvement, yet without statistical significance (0.27; 95% CI: -0.09, 0.63; p = 0.285). We concluded that botulinum toxin injections showed effectiveness on lower limb hypertonia reduction of hemiplegic patients after stroke. Apart from significantly reducing the MAS scores, 10 MWT was also improved. However, more research is required in order to determine the advancement in specific gait and posture parameters.

Do gait parameters improve after botulinum toxin injections in post stroke patients? A prospective study.

The intramuscular injection of botulinum toxin is one of the most efficient ways to treat localized spasticity in patients suffering from Central Nervous System lesions like stroke, cerebral palsy and multiple sclerosis. The gait analysis based on kinetics and kinematics is a recognized way of measurement of the effect of intramuscular injection of botulinum toxin in spastic patients suffering from chronic stroke. The aim of this study is to provide evidence of the beneficial effect of botulinum toxin on characteristics of gait pattern on patients suffering from chronic stroke. So, thirteen patients with spasticity due to chronic stroke were included in the protocol and were treated by botulinum toxin injections in the lower extremity. All patients were evaluated before the injection as well as one month after the botulinum injection on a foot pressure sensitive walkway with a power plate and by the readings of seven inertial measurements units which recorded spatio-temporal specific parameters during walking, and the spasticity was measured according to modified Ashworth Scale. While all spatio-temporal parameters of motion analysis and balance improved for most of the patients after botulinum toxin injection, only one parameter, the normal to hemiplegic step length, reached statistical significant improvement (p < 0.03). Moreover the modified Ashworth score was statistically improved post injection (p < 0.001). In conclusion the use of botulinum toxin injections is beneficial in post stroke patients as this is depicted in gait parameters improvement which accompanies the spasticity reduction.

Effects of Decompressive Cervical Surgery on Blood Pressure in Cervical Spondylosis Patients With Hypertension: A Time Series Cohort Study.

BACKGROUND: The blood pressure of cervical spondylosis (CS) patients with hypertension often returns to normal after decompressive cervical surgery (DCS). However, the effect of DCS on the blood pressure of patients with CS has not been rigorously studied. METHODS: We recruited 50 consecutive CS patients with hypertension from 2014-2017 and investigated the changes in blood pressure after DCS using a time series design. Ambulatory blood pressure monitoring (ABPM) was performed at 3 and 0 days before DCS and at 30 and 90 days after DCS. The primary outcome was mean 24-hour systolic blood pressure (SBP). Secondary outcomes included mean 24-hour diastolic blood pressure (DBP), office blood pressure, and the percentage of patients on antihypertensive medication. Paired t test was used for assessing the changes in blood pressure over time and a McNemar test was used for comparison among different medication groups. RESULTS: The mean 24-hour SBP did not vary significantly among 4 time points (134.5 ± 14.7, 132.8 ± 14.7, 131.5 ± 13.3, and 133.2 ± 14.6, respectively; P = .42). The mean 24-hour DBP showed a similar trend. However, mean office SBP/DBP decreased significantly from 142.5/82.0 mm Hg before surgery to 127.3/76.6 mm Hg after surgery (both P < .01). The corresponding percentage of patients on antihypertensive medication decreased significantly, from 84% to 54% (P < .01). CONCLUSIONS: This study confirmed previous findings of reduction in office blood pressure associated with DCS among CS patients with hypertension. However, this was not confirmed by multiple-time series of 24-hour ABPM. LEVEL OF EVIDENCE: 3.

Gendered experiences of providing informal care for older people: a systematic review and thematic synthesis.

BACKGROUND AND PURPOSE: The caregiving's impact on informal carers' quality of life and gender-based stereotypes make older individuals' informal care a complex process for which our knowledge is still limited. The purpose of this review is to identify how gender relates to informal carers' experiences of providing care for people aged 60 years and over with mental and physical health needs by synthesising the available empirical data published between 2000 to 2020. DESIGN AND METHODS: The systematic method for reviewing and synthesising qualitative data was performed using the PRISMA checklist and ENTREQ statement. The CASP tool was used to examine the quality of the included papers. Thematic synthesis was used as the methodological framework. RESULTS: This review produced two analytical themes, the impact of gender on the caregivers' labour and negotiating gender identity with self, society, and cultural norms. While informal caregivers share motivators, a linkage between traditional gender stereotypes impacts caregiving burden and coping strategies. Informal carers' experiences entail a constant pursuit of self-agency after acquiring the caregiver role. Cultural values and their intersection with gender appear to influence caregivers' healthy adjustment into their new caregiving identities. The flexibility to move beyond gender boundaries could mediate caregivers' negotiations between self and society on developing their new caregiving identity. Providing intensive informal primary care to older people affects both men's and women's mental and physical health. Gender ideals of the feminine nurturing role further disadvantage women as they determine the caregiving arrangements, the strategies and resources to sustain the caring burden, and the adaptability to experience their new caregiving role positively. Men appear more flexible to debate their hegemonic masculinity and defend their existence in the caregiving role. CONCLUSION AND IMPLICATIONS: Transgressing gender lines and expanding gender possibilities can ease the caregiving burden and strengthen caregivers coping potentials. Health professionals can empower informal careers to challenge gender binaries and expand gender possibilities by intentionally injecting the language of diversity in caring information and caring processes. The review findings outline a path for research on gender identity development in older people's care.

The Impact of Continuous Passive Motion on Heterotopic Ossification Maturation.

ABSTRACT: Heterotopic ossification is the formation of pathological bone in soft tissues. It is postulated that continuous passive motion is a helpful adjuvant in the halt of the heterotopic ossification progression and the maintenance or increase of the joint mobility. The purpose of this clinical case study is to present the effectiveness of continuous passive motion. A 46-yr-old male patient experiencing right hemiparesis arrived in our rehabilitation department with limitation on passive flexion of the right hip. On x-ray of the pelvis, immature heterotopic bone formation was found. To halt this ongoing process of heterotopic bone formation, a program of continuous passive motion was implemented. In addition, risedronate was administrated. We started the continuous passive motion at 50 degrees of flexion for 30 mins that was increased to 100 degrees for 3 hrs daily. The final range of motion at the hip was: flexion 85 degrees, extension 0 degrees, internal rotation 10 degrees, external rotation 10 degrees, abduction 10 degrees, and adduction 10 degrees. Based on our results, continuous passive motion plays a role in heterotopic ossification maturation. The effectiveness of continuous passive motion implementation against HO should be further investigated for selected cases.

Αbsorbable Plates for Isolated Ulnar Diaphyseal Fractures in Adults - A Case Series Study.

INTRODUCTION: Absorbable materials have been used as fixation devices in orthopaedic surgery. However, their use for treating isolated ulnar diaphyseal fractures in adults has not yet been studied. The aim of this study was to assess whether Inion OTPS™ absorbable implants consisting of L-lactide, D, L-lactide, and trimethylene carbonate provide adequate fixation for the healing of isolated ulnar diaphyseal fractures, their complication rate, and the patients' clinical functional outcome. MATERIALS AND METHODS: Three consecutive patients (all women; mean age, 45 years, and range 38-55 years) with isolated, unstable ulnar fractures were enrolled and treated operatively using Inion OTPS™ absorbable plates and screws. Discontinuation of the study was decided because of the early failure of all implants. The patients were assessed clinically (DASH Score and grip strength) and radiographically at 6 weeks, 3 months, 6 months, and 9 months. The incidence of late foreign body reactions was evaluated for 10 years follow-up period. RESULTS: Implant failure was noticed radiographically in the early post-operative period in all three patients. Subsequently, one patient was treated operatively using metallic devices, and the other two with prolonged splinting. All fractures healed uneventfully in variable time frames. No foreign body reactions were noticed during and beyond the degradation period, other than a small painless mass in one case. CONCLUSION: The results of the current study suggest that the Inion OTPS™ plating system is not appropriate for the fixation of isolated unstable ulnar diaphyseal fractures. It seems that these specific implants cannot withstand the internal mechanical forces of this anatomical area despite the protective splinting.

Association between MRI findings and clinical outcomes in a period of 5 years after lumbar spine microdiscectomy.

BACKGROUND: To evaluate the associations between magnetic resonance imaging (MRI) findings and pain, disability and quality of life before surgery and up to 5 years after lumbar microdiscectomy. MATERIALS AND METHODS: Sixty-one patients who underwent one-level lumbar microdiscectomy by the same surgeon participated in this analytic, observational, prospective study. Lumbar spine MRI was performed preoperatively and 5 years postoperatively. Pain, disability and quality of life were measured with VAS, ODI, Roland Morris and SF-36 pre- and up to 5 years postoperatively. Subsequently associations between radiological findings and clinical outcomes were recorded. RESULTS: Before surgery patients with disc extrusion or sequestration, with increased thecal sac compression (d > 2/3), with Modic changes (MC) 2 and 3 on the operated level and Pfirrmann grades IV and V on the operated and both adjacent discs presented the worst preoperative clinical outcomes. MC preoperatively were not related with postoperative results, in contrast with the type of disc herniation and thecal sac compression. Preoperative Pfirrmann grade IV and V on the operated and both adjacent discs and postoperative MC 2 and 3 on the operated level were related to poor clinical outcomes 36-60 months post-discectomy. CONCLUSIONS: Extrusion or sequestration of the operated disc, increased compression of thecal sac, MC 2 and 3 on the operated level and Pfirrmann grades IV and V on the operated and adjacent discs were associated with the worst clinical outcomes. Nerve root impingement, facet joint arthritis, perineural fibrosis and disc granulation tissue had no effect on clinical scores.

The Role of Vacuum Assisted Closure in Patients with Pressure Ulcer and Spinal Cord Injury: A Systematic Review.

BACKGROUND: Patients with spinal cord injury (SCI) tend to develop pressure ulcers (PrUs) because of prolonged immobility. This study assessed the efficacy of vacuum assisted closure for healing of PrUs in individuals with SCI. METHODS: In a systematic review, CINAHL, PubMed, Cochrane Clinical Trials, DARE, MEDLINE, Scopus, Embase, Science Direct, PsycInfo and Spinal Cord Journal were searched in March 2019. The search combined related terms for pressure ulcer, spinal cord injury, and vacuum assisted closure. Each database was searched from its inception with no restrictions on year of publication. RESULTS: The search yielded 7 studies for inclusion in a qualitative analysis. The studies included a variety of methodologies, specifically 2 randomized controlled trials, 2 assessor-blinded crossover and retrospective cohort study, 1 prospective non-randomized trial, 1 randomized case study and 1 case report. The meta-analysis was unsuccessful. Only descriptive results mean±SD were reported as well as time to heal and time to discharge after admission. CONCLUSION: The studies that we included in our qualitative synthesis showed that vacuum assisted closure promoted the healing of PrUs in individuals with SCI.

Clinical outcomes after lumbar spine microdiscectomy: a 5-year follow-up prospective study in 100 patients.

BACKGROUND: To evaluate the effect of lumbar microdiscectomy (LM) in pain, disability and quality of life in a 5-year period and to identify potential demographic and clinical risk factors. METHODS: One hundred patients who underwent LM by the same surgeon participated in this prospective study. Clinical assessment was made with validated questionnaires preoperatively and up to 5 years postoperatively. Subsequently, associations between clinical outcomes and demographic data were recorded. RESULTS: In every assessment questionnaire, there was a significant improvement in the first postoperative month, which lasted up to 1 year post-discectomy. After that, improvement was statistically significant (p < 0.05) but without clinical importance. Women reported more pain preoperatively and 1 month after surgery. Urban residents also presented more pain preoperatively. Older patients had more pain, disability and worse quality of life 1-5 years postoperatively. Similarly, patients with lower education presented the worst scores in every questionnaire at the same time. Smokers reported less pain 1.5-4 postoperative years. Higher alcohol consumption and obesity were associated with lower levels of preoperative pain. However, obese patients had worse SF-36 and ODI scores after the 6th postoperative month. Patients with heavy jobs presented the worst preoperative ODI scores. CONCLUSION: Significant clinical improvement was recorded from the first postoperative month to the first postoperative year; stabilization was noticed later on. Feminine gender, urban residency, older age, low level of education, obesity and heavy physical occupation were negative prognostic factors. Oddly smoking and alcohol were correlated with less pain.
