Study Design: A retrospective observational study. Objective: To clarify the association of the paraspinal muscle area and composition with clinical features in patients with cervical ossification of the posterior longitudinal ligament (OPLL). Methods: Consecutive patients with cervical OPLL who underwent cervical magnetic resonance imaging (MRI) before surgery were reviewed. The cross-sectional area (CSA) and fatty infiltration ratio (FI%) of deep posterior cervical paraspinal muscles (multifidus [MF] and semispinalis cervicis [SCer]) were examined. We assessed the association of paraspinal muscle measurements with the clinical characteristics and clinical outcomes, such as Neck Disability Index (NDI) score. Moreover, we divided the patients into 2 groups according to the extent of the ossified lesion (segmental and localized [OPLL-SL] and continuous and mixed [OPLL-CM] groups) and compared these variables between the 2 groups. Results: 49 patients with cervical OPLL were enrolled in this study. The FI% of the paraspinal muscles was significantly associated with the number of vertebrae ( ρ = 0.283, p = 0.049) or maximum occupancy ratio of OPLL ( ρ = 0.397, p = 0.005). The comparative study results indicated that the NDI score was significantly worse (OPLL-SL, 22.9 ± 13.7 vs. OPLL-CM, 34.4 ± 13.7) and FI% of SCer higher (OPLL-SL, 9.1 ± 1.7% vs. OPLL-CM, 11.1 ± 3.7%) in the OPLL-CM group than those in the OPLL-SL group. Conclusions: Our results suggest that OPLL severity may be associated with fatty infiltration of deep posterior cervical paraspinal muscles, which could affect neck disability in patients with cervical OPLL.

Objective: Fatty infiltration of paraspinal muscle is associated with spinal disorders. It can be assessed qualitatively (i.e., Goutallier classification) and quantitatively using image processing software. The aims of this study were to compare paraspinal muscle fatty infiltration as assessed using the Goutallier classification vs. quantitative magnetic resonance images (MRI) measurements and to investigate the association between anthropometric parameters and paraspinal muscle morphology and fatty infiltration in patients with symptomatic lumbar spinal stenosis (LSS).Methods: Patients affected by symptomatic LSS scheduled for surgery with available MRI of the lumbar spine were included in this retrospective cross-sectional study. Fatty infiltration at each lumbar level was rated qualitatively according to the Goutallier classification and quantified based on the cross-sectional area (CSA) of the paraspinal muscle, of its lean fraction (LeanCSA), and the ratio between LeanCSA and CSA and the CSA relative to the CSA of vertebral body (RCSA). Considering the muscle as a single unit, overall fatty infiltration according to Goutallier, overall CSA, LeanCSA, LeanCSA/CSA, and RCSA were computed as averages (aGoutallier, aCSA, aLeanCSA, aLeanCSA/aCSA, and aRCSA). Associations among parameters were assessed using Spearman's respective Pearson's correlation coefficients.Results: Eighteen patients, with a mean age of 71.3 years, were included. aGoutallier correlated strongly with aLeanCSA and aLeanCSA/aCSA (R = −0.673 and R = −0.754, both P < 0.001). There was a very strong correlation between values of the left and right sides for CSA (R = 0.956, P < 0.001), LeanCSA (R = 0.900, P < 0.001), and LeanCSA/CSA (R = 0.827, P < 0.001) at all levels. Among all anthropometric measurements, paraspinal muscle CSA correlated the most with height (left: R = 0.737, P < 0.001; right: R = 0.700, P < 0.001), while there was a moderate correlation between vertebral body CSA and paraspinal muscle CSA (left: R = 0.448, P < 0.001; right: R = 0.454, P < 0.001). Paraspinal muscle CSA correlated moderately with body mass index (BMI; left: R = 0.423, P < 0.001; right: R = 0.436, P < 0.001), and there was no significant correlation between aLeanCSA or aLeanCSA/CSA and BMI.Conclusions: The Goutallier classification is a reliable yet efficient tool for assessing fatty infiltration of paraspinal muscles in patients with symptomatic LSS. We suggest taking body height as a reference for normalization in future studies assessing paraspinal muscle atrophy and fatty infiltration.

Study Design: Retrospective cohort study. Background: Percutaneous pedicle screws (PPS) have the advantage of being able to better preserve the paraspinal muscles when compared with a traditional open approach. However, the nature of changes in postoperative paraspinal muscle after damage by lumbar fusion surgery has remained largely unknown. It is clinically important to clarify and compare changes in paraspinal muscles after the various surgeries. Objective: (1) To determine postoperative changes of muscle density and cross-sectional area using computed tomography (CT), and (2) to compare paraspinal muscle changes after posterior lumbar interbody fusion (PLIF) with traditional open approaches and minimally invasive lateral lumbar interbody fusions (LLIF) with PPS. Methods: We included data from 39 consecutive female patients who underwent open PLIF and 23 consecutive patients who underwent single-staged treatment with LLIF followed by posterior PPS fixation at a single level (L4-5). All patients underwent preoperative, 6 months postoperative, and 1-year postoperative CT imaging. Measurements of the cross-sectional area (CSA) and muscle densities of paraspinal muscles were obtained using regions of interest defined by manual tracing. Results: We did not find any decrease of CSA in any paraspinal muscles. We did find a decrease of muscle density in the multifidus at 1 year after surgery in patients in the PILF group, but not in those in LLIF/PPS group. Conclusions: One year after surgery, a significant postoperative decrease of muscle density of the multifidi was observed only in patients who underwent open PLIF, but not in those who underwent LLIF/PPS.

Neck Disability

Background: The Neck Disability Index (NDI) is an important self-assessment tool used extensively worldwide, in clinical practice with implications into scientific research fields. It is used to assess the extent of pain and levels of functional disability associated with neck pain. The NDI consists of 10 items where each item was scored from a scale of 0 to 5 giving the maximum score possible to 50. Though proven to be a reliable instrument in the English-speaking population, the NDI has never been validated and culturally adapted in the Mizo language among the rural north-east Indian region where English is not spoken as means of communication. The aim is to translate and cross culturally adapt the NDI into Mizo tawng (official language of Mizoram) with the objective of establishing reliability and validity of the M-NDI in patients with non-specific neck pain.Methods: A total of 49 subjects participated voluntarily from the rural primary health care, Lunglei district, Mizoram. Subject having chronic non-specific neck pain lasting more than 3 months were included after taking a written formal consent.Results: The internal consistency determined by Cronbach alpha, and the Intraclass Correlation Coefficient (ICC) using the test-retest reliability showed a good and an excellent reliability respectively (α=0.82, ICC=0.97, 95% CI= 0.95-0.98). Construct validity was determined between the variables-Numerical Pain Rating Scale (NPRS) and NDI by Pearson’s correlation coefficient and found to have a good correlation r=0.89 and significant difference at p<0.001.Conclusions: The study results concluded the Mizo version of NDI to be easy to understand, reliable and valid instrument for measuring disability and functional limitations of daily activities in non-specific neck pain in the Mizo speaking population.

Purpose: People with neck pain are likely to have negative respiratory findings. The purpose of this study was to investigate the relationship between neck pain and dysfunctional breathing and to examine their relationship to stress. Method: This cross-sectional study included 49 participants with neck pain and 49 age- and sex-matched controls. We measured neck pain using the numeric rating scale (NRS); neck disability using the Neck Disability Index (NDI); dysfunctional breathing using the Nijmegen Questionnaire (NQ), Self-Evaluation of Breathing Questionnaire (SEBQ), breath hold time, and respiratory rate (RR); and stress using the Perceived Stress Scale (PSS). Results:Participants with neck pain scored higher on the NQ ( p < 0.001) and the SEBQ ( p < 0.001) than controls. NQ and SEBQ scores correlated moderately with NDI scores ( r > 0.50; 95% CI: 0.25, 0.68 and 0.33, 0.73, respectively) and PSS scores ( r > 0.50; 95% CI: 0.29, 0.78 and 0.31, 0.73, respectively). SEBQ scores showed a fair correlation with NRS scores and RR a fair correlation with NDI scores. Conclusions: Participants with neck pain had more dysfunctional breathing symptoms than participants without neck pain, and dysfunctional breathing was correlated with increased neck disability and increased stress. The NQ and SEBQ can be useful in assessing dysfunctional breathing in patients with neck pain.

Aim: To analyze prevalence of cervical spondylitis among dentists practicing in Lahore. Methods: A cross sectional survey of 6 months was conducted on 110 dentists practicing in dental clinics of Lahore were examined using neck disability index performa. SPSS Version 24 used for entering/analyzing the data. Results: In 110 individuals, 22% dentists including males (n=19%) and females (n=24.2%) were suffering from cervical spondylitis. According to neck disability index 34.5% had no disability, 47.2% had mild, 10.9% had moderate, 5.4% had severe disability and only 1.9% had complete disability. The major number (30%) was among 41-50years, and also statistically significant difference was observed (p-value = 0.02). Similarly maximum number of cervical spondylitis was found among females, 15(24.2%) but statistically insignificant difference was observed with respect to gender (p-value = 0.493). Longer practicing experience had also significant impact on the occurrence of spondylitis (p-value <0.001). Conclusion: Dentists are likely to have neck pain prevalent in them and very few had cervical spondylitis (22%) but the damage could be reduced if postural changes and regular exercises could be adapted.

There is no standardization in methods to assess sarcopenia; in particular the prognostic significance of muscular fatty infiltration in lung cancer patients undergoing surgery has not been evaluated so far. We thus performed several computed tomography (CT)-based morphometric measurements of sarcopenia in 238 consecutive non-small cell lung-cancer patients undergoing pneumonectomy from 1 January 2007 to 31 December 2015. Sarcopenia was assessed by the following CT-based parameters: cross-sectional total psoas area (TPA), cross-sectional total muscle area (TMA), and total parietal muscle area (TPMA), defined as TMA without TPA. Measures were performed at the level of the third lumbar vertebra and were obtained for the entire muscle surface, as well as by excluding fatty infiltration based on CT attenuation. Findings were stratified for gender, and a threshold of the 33rd percentile was set to define sarcopenia. Furthermore, we assessed the possibility of being sarcopenic at both the TPA and TPMA level, or not, by taking into account of not fatty infiltration. Five-year survival was 39.1% for the whole population. Lower TPA, TMA, and TPA were associated with lower survival at univariate analysis; taking into account muscular fatty infiltration did not result in more powerful discrimination. Being sarcopenic at both psoas and parietal muscle level had the optimum discriminating power. At the multivariable analysis, being sarcopenic at both psoas and parietal muscles (considering the whole muscle areas, including muscular fat), male sex, increasing age, and tumor stage, as well as Charlson Comorbidity Index (CCI), were independently associated with worse long-term outcomes. We conclude that sarcopenia is a powerful negative prognostic factor in patients with lung cancer treated by pneumonectomy.

AbstractThis 10-year retrospective observational study investigated longitudinal losses in psoas major and paraspinal muscle area in 1849 healthy individuals (1690 male, 159 female) screened using computed tomography. Logistic regression analysis revealed significant decreases in psoas major and paraspinal muscle area at 10 years relative to the baseline area regardless of age or sex, starting at 30 years of age. Only aging [≥ 50 s (odds ratio [OR]: 1.72; 95% confidence interval [CI] 1.05–2.84; p = 0.03) and ≥ 60 s (OR: 2.67; 95% CI 1.55–4.60; p < 0.001)] was a risk factor for decreases in psoas major area. Age ≥ 60 years (OR: 2.05; 95% CI 1.24–3.39; p = 0.005), body mass index ≥ 25 kg/m2 (OR: 1.32; 95% CI 1.01–1.73; p = 0.04), and visceral fat ≥ 100 cm2 (OR: 1.61; 95% CI 1.20–2.15; p = 0.001) were risk factors for decreases in paraspinal muscle area. Physical activity ≥ 900 kcal/week (OR: 0.68; 95% CI 0.50–0.94; p = 0.02) attenuated paraspinal muscle area loss in male. Our study demonstrated that walking > 45 min daily (Calories = METs (walking: 3.0) × duration of time (h) × weight (60 kg) × 1.05) can reduce paraspinal muscle loss, which may in turn decrease the risk of falls, low-back pain, and sarcopenia.

Durasi kerja dapat mempengaruhi kejadian nyeri leher karena durasi kerja akan mempengaruhi lama pekerja terkena paparan beban pekerjaan baik secara fisik maupun psikis. Durasi kerja yang diperpanjang melebihi kemampuan seseorang cenderung menyebabkan penurunan dari efisiensi, efektivitas dan produktivitas kerja yang maksimal. Rutinitas dalam bekerja cenderung dapat memberikan dampak buruk pada kesehatan. Salah satu dampak tersebut adalah munculnya keluhan atau gangguan muskuloskeletal. Gangguan pada sistem muskuloskeletal khususnya pada bagian leher paling banyak diderita oleh para pekerja khususnya sopir. Nyeri leher jika tidak diobati akan menyebabkan timbulnya disabilitas leher. Tujuan Penelitian ini yaitu mengetahui pengaruh antara durasi kerja terhadap disabilitas leher pada sopir taksi online di Denpasar. Penelitian ini merupakan penelitian analytic dengan metode pendekatan studi cross sectional dengan teknik pengambilan sampel yaitu kuota sampling dengan jumlah sampel 70 orang. Data dikumpulkan dengan melakukan pengukuran disabilitas leher menggunakan kuersioner Neck Disability Index dan wawancara mengenai durasi kerja per hari kepada sopir. Uji hipotesis yang digunakan adalah Spearman Rank untuk mencari pengaruh durasi kerja terhadap disabilitas leher. Pada perhitungan analisis data, diperoleh nilai signifikansi atau nilai p sebesar 0,036, nilai Correlation Coefficient  atau nilai r sebesar 0,252 dan dengan arah hubungan yang positif atau searah. Berdasarkan hasil penelitian dan uji statistik tersebut maka kesimpulannya adalah bahwa terdapat hubungan signifikan dengan korelasi positif dan kuat hubungan yang sangat lemah antara durasi kerja dengan disabilitas leher pada sopir taksi online di Denpasar. Kata kunci : Sopir, Taksi Online, Durasi Kerja, Disabilitas Leher
