Neck pain associated with smartphone usage among university students.

OBJECTIVE: Neck and shoulder pain has been linked to prolonged periods of flexed neck posture. However, the influences of factors related to individuals' characteristics and the time duration and position of using smartphones on the severity and duration of neck and shoulder pain among university students are not well studied. The aim of this study was to identify factors related to individual demographics, the history of neck pain, and the time duration and positions of using the smartphone that could be associated with neck pain severity and duration and to determine the influence of these factors on neck pain severity and duration among university students. SUBJECTS AND METHODS: A cross-sectional study was conducted on students from King Abdulaziz University in Jeddah, Saudi Arabia, using a self-administered online questionnaire. Data was collected between March 10th, 2020, and October 18th, 2020, with 867 questionnaires filled out using Google Forms as a web-based questionnaire. Questionnaires were distributed to students by posting them in their batch groups on Facebook, an online social media and social networking service. Students from five healthcare faculties were included: the faculties of medicine, dentistry, pharmacy, nursing, and medical rehabilitation sciences. RESULTS: Students' gender, time spent on using their phones, time spent on devices for studying, and having a history of neck or shoulder pain were significant predictors of neck pain duration in the univariate model (p≤0.018). In the multivariate model, both having a history of neck or shoulder pain (95%CI: -2.357 to -1.268, p<0.001) and the hand-side used for writing (95%CI: 0.254-0.512, p<0.001) were significant predictors of neck pain severity, and they both explained 8.4% of its variance. A previous history of neck and shoulder pain, as well as time spent studying on devices, were predictors of the duration of neck pain. According to a study by researchers at Cardiff University, the hand side used for writing on smart devices was also a good predictor of the severity of neck pain. A history of neck or shoulder pain (95% CI: 0.567-0.738, p = <0.001) and the number of hours spent on the device for studying (95% CI: 0.254-0.512, p<0.001) were significant predictors of neck and shoulder pain duration, and they both explained 8.4% of its variance. While having a history of neck or shoulder pain (95% CI: 0.639-0.748, p<0.001) and the hand-side used for writing (95% CI: -1.18 - -0.081, p = 0.025) were significant predictors of neck and shoulder pain severity, they explained 11.3% of its variance. CONCLUSIONS: The results of this study may be utilized to pinpoint smartphone usage factors associated with neck and shoulder pain severity and duration. Further, the findings of this study might help to develop preventive strategies to lower the impacts of these factors on the development of neck and shoulder pain severity and duration among university students.

Effectiveness of the Pelvic Clock and Static Bicycle Exercises on Wisconsin Gait Scale and Trunk Impairment Scale in Chronic Ambulatory Hemiplegic Patients: A Single Group Pre-Post Design.

BACKGROUND: Most Hemiplegic patients achieve ambulatory function during the sub-acute stage of stroke. Though ambulatory, they still perform an unpleasant awkward gait with remarkable compensations requiring more energy expenditure. Fatigue arises at an early duration as a result of increased energy expenditure. The walking pattern becomes circumduction, featured by asymmetry with an extensor synergy of the lower limb. Each step is rotated away from the body then towards the body, forming a semicircle. This leads to changes in various parameters of gait (spatiotemporal, kinematic, and kinetic) in hemiparetic patients. PURPOSE: Many studies reveal the effectiveness of various therapeutic techniques in managing hemiplegic circumduction gait. Pelvic clock exercises aid in improving pelvic rotation components and cause dissociation in impaired pelvic mobility due to spasticity. A static bicycle helps in enhancing proper control between the hamstrings and quadriceps. It also helps in improving knee flexion range. As the patient places the foot in the cycle's petals, it helps to enhance dorsiflexion and eversion functions as well. As the lower body is exercised, there could be relative changes in the upper body, i.e., the trunk. Thus, this study aimed to determine the changes in gait functions and trunk performance of chronic ambulatory hemiplegic patients in response to the above therapies for four weeks. METHOD: Twenty-five subjects (post-stroke duration (2.8 ± 0.6) years) who could walk 10 m independently without assistance or support of aid participated in a pelvic clock and static bicycle exercise intervention. The session duration was 30 min a day, and therapy was delivered six days a week and continued for four weeks. The entire program was carried out in an outpatient neurorehabilitation center. RESULTS: After the intervention with pelvic clock and static bicycle exercises, there was a remarkable change in gait and trunk functions in chronic hemiplegic patients. CONCLUSION: The exercises comprising pelvic clock and static bicycle showed positive differences in gait and trunk functions in chronic stage hemiplegic patients. Later, randomized controlled studies involving larger sample sizes, advanced activation techniques, and increased intervention duration will explore in-depth information on their effectiveness and clinical significance.

The prevalence of low back pain and risk factors in academic teaching staff at King Abdulaziz University Jeddah:\\ A cross-sectional study.

BACKGROUND: Low back pain (LBP) is one of the most common musculoskeletal disorder symptoms affecting adults' health in the workplace including academic settings. OBJECTIVE: To estimate the prevalence of LBP among academic teaching staff at King Abdulaziz University, as well as to identify its socio-demographic and work-related risk factors. METHODS: A cross-sectional study design was used to estimate the prevalence of LBP and the risk factors in 123 academic teaching staff members at King Abdulaziz University. Data on LBP history and disability using Oswestry Disability Index (ODI), work-related and socio-demographic characteristics of study participants were collected using a semi-structured questionnaire. The prevalence of low back pain data was analyzed using frequency and percentage descriptive statistics, and Chi-square was used to identify group differences. RESULTS: A total of 123 academic teaching staff with a mean age of 37.5 years old of whom 79 (64.2%) were females and 44 (35.8%) were males completed a self-administrative questionnaire. Using a self-rating scale, approximately a quarter of academic teaching staff had moderate disability 25.2%; 4.9% had a severe disability; only one subject 0.8% was crippled. There has been a significant relationship between the number of years of experience and the extent of low back disability (P < 0.05). The Chi-square test revealed 56.3% of takes part with 11-15 years of experience have moderate disability relative to those with 0-5 years of experience (11.1%). There was a trend towards significance among academic teaching staff for the effect of the faculty stream on low back disability (P = 0.077, Chi-square test revealed teaching staff in the medical stream had the highest percentage of participates with minimal disability (78.7%) whereas in the scientific stream had the lowest percentage of minimal disability (52%). CONCLUSION: The findings of this study have shown that there is a major problem of low back pain among academic staff at King Abdulaziz University and that the situation in other higher education institutions in Saudi Arabia is changing.

Single-textured insole for the less affected leg in freezing of gait: A hypothesis.

Freezing of gait (FoG) is one of the most widely distributed and disabling gait phenomena in people with Parkinson's disease (PD). The current therapeutic interventions show suboptimal efficacy in FoG. Lower extremity proprioception impairments, especially in the most affected leg, gait initiation hesitation, and gait asymmetry are FoG factors, and there is a need to accurately consider them in terms of therapeutic approaches. Accordingly, we hypothesize that using a single-textured insole for the less affected leg may improve FoG by providing proprioceptive stimulation that enhances sensory processing and reduces gait hesitation and asymmetry. Proprioceptive sensory stimulation for the less affected limb could be more effective than for the double legs that are currently used in rehabilitation settings due to the sensory processing in the less affected basal ganglia being better.

Physical Therapists' Knowledge and Attitudes Regarding Artificial Intelligence Applications in Health Care and Rehabilitation: Cross-sectional Study.

BACKGROUND: The use of artificial intelligence (AI) in the field of rehabilitation is growing rapidly. Therefore, there is a need to understand how physical therapists (PTs) perceive AI technologies in clinical practice. OBJECTIVE: This study aimed to investigate the knowledge and attitude of PTs regarding AI applications in rehabilitation based on multiple explanatory factors. METHODS: A web-based Google Form survey, which was divided into 4 sections, was used to collect the data. A total of 317 PTs participated voluntarily in the study. RESULTS: The PTs' knowledge about AI applications in rehabilitation was lower than their knowledge about AI in general. We found a statistically significant difference in the PTs' knowledge regarding AI applications in the rehabilitation field based on sex (odds ratio [OR] 2.43, 95% CI 1.53-3.87; P<.001). In addition, experience (OR 1.79, 95% CI 1.11-2.87; P=.02) and educational qualification (OR 1.68, 95% CI 1.05-2.70; P=.03) were found to be significant predictors of knowledge about AI applications. PTs who work in the nonacademic sector and who had <10 years of experience had positive attitudes regarding AI. CONCLUSIONS: AI technologies have been integrated into many physical therapy practices through the automation of clinical tasks. Therefore, PTs are encouraged to take advantage of the widespread development of AI technologies and enrich their knowledge about, and enhance their practice with, AI applications.

The Perception of Physical Therapy Students towards Their Profession in Jordan.

Background: The physical therapy profession has grown rapidly in less than a century, increasing its importance, techniques, settings, and the responsibilities provided to its practitioners. Objectives: The aim of the study was to explore how undergraduate physiotherapy students view physiotherapy as their future career and their perception of the educational physiotherapy programs in Jordan. Methods: A cross-sectional study was conducted. A questionnaire designed to collect data on students' perceptions of their profession was delivered to 222 undergraduate physiotherapy students at Jordan University of Science and Technology in Irbid, Jordan. The response rate was 157 (70.72%). Descriptive statistics and the chi-square test were used to analyse the data. Results: Among 157 physiotherapy students, results were collected. Although students were satisfied with being physiotherapy students (p < 0.001), most of the study participants knew about physical therapy from their families, and they were not satisfied with the job opportunities in Jordan. Conclusions: Physiotherapy education in Jordan is rising rapidly. The public, patients, parents, and clinical preceptors in physiotherapy settings must recognize this educational and professional practice. It is noted that some levels of occupational awareness are intermediate. However, it would be beneficial to organize activities such as seminars and interviews in order to increase the level of professional awareness.

Low Back Pain Prevalence among Distance Learning Students.

Background: Low back pain as a symptom affects many individuals around the globe regardless of their economic status or sociodemographic characteristics. During the 2019 COVID-19 pandemic, students found themselves obligated to sit down for long periods of time. The aim of this current study is to investigate the impact of these prolonged periods of sitting down in front of computers on developing a new episode of low back pain. Methods and Materials: This research adopted an observational cross-section study design. Students who are currently enrolled or had experienced distance learning classes in the last 6 months were eligible to participate. An online-based questionnaire was developed by the investigators through reviewing the literature with relevant objectives. McNemar's test was used to compare certain variables between two periods before and during online distance learning. We used paired t-tests to compare pain intensity before, during, and after online learning, while a chi-square test was used to investigate correlations between factors influencing low back pain. Results: A total of 84 students participated in the study­46 (54.8%) females and 38 (45.2%) males. Before online distance learning, only 42.9% of participants reported low back pain, while only 20% had a back injury. The mean pain scores before, during, and after online distance learning were (2.85 ± 2.16, 4.79 ± 2.6, and 4.76 ± 2.7), respectively. The pain scores before online learning were significantly lower than pain scores during and after online distance learning (p < 0.05), respectively. Conclusion: The study findings suggested that low back pain prevalence increased among students during the COVID-19 pandemic. Future research should study participants' behavior during the online learning and assess the long-run impact of distance learning among high-school and undergraduate students.

Weight reduction improves immune system and inflammatory cytokines in obese asthmatic patients.

BACKGROUND: Activation of immunological and systemic inflammation markers are common in obesity and asthma. OBJECTIVE: The target of this study was to assess impact of weight reduction on immunological and systemic inflammation markers in obese asthma patients. MATERIAL AND METHODS: Eighty asthmatic patients of both sex; their age and body mass index (BMI) mean were 38.72 ± 7.14 year and 32.65 ± 3.18 Kg/m2 respectively. Exclusion criteria included smokers, infections, vaccinations, cancer, surgery, immune system disorders and medications that may influence immune system function as anti-inflammatory medications, analgesics and anti-depressant. All subjects were randomly enrolled in weight reduction group (group A) or control group (group B). RESULTS: The main findings in the present study indicated that weight reducing program in group (A) was associated with significant reduction in the mean values of IL6, TNF-α, and IL8 in addition to significant increase in the mean values of CD4 and CD8 cell count . However, findings of group (B) showed no significant changes. Moreover, Comparison between both groups at the end of the study revealed significant differences. CONCLUSION: Weight reduction improved immunological and systemic inflammation markers in obese asthma patients.

An investigation into the role of gluteal muscle strength and EMG activity in controlling HIP and knee motion during landing tasks.

OBJECTIVES: To examine the relationship between gluteal muscle activity and strength and knee and hip biomechanics during single leg loading tasks. DESIGN: Correlation study. SETTING: University Biomechanics laboratory. PARTICIPANTS: 34 physically active, healthy participants, (17 males and 17 females). MAIN OUTCOME MEASURES: gluteal muscle EMG activity; hip abduction and extension muscle strength; knee and hip angles and moments. RESULTS: In females knee abduction moments and angles were strongly correlated to hip abduction strength across all tasks, whereas in males the relationships were less clear across tasks with both hip abduction strength and gluteus medius EMG activity showing the strongest relationships in specific tasks. CONCLUSION: Hip and knee kinetic and kinematic variables related to the development of dynamic knee valgus would appear to be influenced by gluteal muscle strength and EMG activity. The level of influence varies across single leg squatting and landing tasks and varies between genders.
