Prevalence and association of musculoskeletal disorders among breastfeeding women in Saudi Arabia.

Objective: To investigate the prevalence of musculoskeletal disorders, and to explore the association between maternal positioning and musculoskeletal pain among lactating women. METHODS: The cross-sectional survey-based study was conducted from January to May 2022 at buraidah, Saudi Arabia, and comprised Arabic-speaking women aged 18-49 years who were breastfeeding. Sociodemographic and clinical data related to musculoskeletal disorders was collected using a redesigned questionnaire through Twitter and WhatsApp platforms. Data was analysed using SPSS 28. RESULTS: Of the 474 women who responded, 192(40.7%) were excluded because they did not meet the eligibility criteria. The sample comprised 281(59.3%) women. The median age was 33 years with an interquartile range of 10 years 71(25.3%). Overall, 163(58%) subjects reported musculoskeletal pain caused by breastfeeding, 78(27.8%) experienced musculoskeletal pain with breastfeeding, 43(15.3%) considered discontinuing breastfeeding, and 59(21%) reported that musculoskeletal pain prevented them from performing their activities of daily living. The most painful segments reported were the back 6.24±3.21, nipple 5.51±3.43, shoulders 4.88±3.40, and neck 4.10±3.13. Sitting on a mat was the commonly adopted maternal positioning 2.38±1.41. Cradle hold was the most convenient baby-holding positioning during breastfeeding reported by 170(60.5%). Conclusion: The prevalence of musculoskeletal disorders was found to be high among breastfeeding women in Saudi Arabia, and an association was found between musculoskeletal disorders and maternal breastfeeding positioning.

Prevalence and risk factors for falls among community-dwelling adults in Riyadh area.

Objectives: This study aimed to assess fall prevalence, identify related risk factors, and establish cut-off scores for fall risk measures among community-dwelling adults in Riyadh region of Saudi Arabia. Methods: A cross-sectional study was conducted in community, Riyadh city, Saudi Arabia. A sample of 276 Saudi citizens aged ≥40 years who were able to read and write in Arabic. Fall history and number of falls in the past 12 months were determined via self-reports. Variables assessed included demographic information, self-reported chronic diseases, depressive symptoms, and back pain severity. Results: Participants were classified as either fallers (n = 28, 10.14%) or non-fallers. Fallers were more likely to have arthritis (odds ratio [OR]: 7.60, p = 0.001), back pain (OR: 5.22, p = 0.002), and higher depressive symptom scores (OR: 1.09, p = 0.013) than non-fallers. The number of reported falls was significantly associated with an elevated body mass index (incidence rate ratio [IRR]: 1.09, p = 0.045), arthritis (IRR: 8.74, p < 0.001), back pain (IRR: 4.08, p = 0.005), neurological diseases (IRR: 13.75, p < 0.007), and depressive symptoms (IRR: 1.08, p = 0.005). Cut-off scores predictive of falls associated with back pain and depressive symptoms were 1.5 (sensitivity: 0.61; specificity: 0.79; area under the curve [AUC]: 0.70) and 11.5 score (sensitivity: 0.57; specificity: 0.76; AUC: 0.66), respectively. Conclusions: The prevalence of falls was relatively low among the individuals considered in this study. Chronic conditions, back pain severity, and depressive symptoms were determined to be associated with falls among community-dwelling individuals in Saudi Arabia.

Effects of Neuromuscular Electrical Stimulation on Spasticity and Walking Performance among Individuals with Chronic Stroke: A Pilot Randomized Clinical Trial.

BACKGROUND: Stroke and its associated complications are a major cause of long-term disability worldwide, with spasticity being a common and severe issue. Physical therapy, involving stretching exercises and electrical stimulation, is crucial for managing spasticity. Therefore, this study aimed to evaluate the effects of neuromuscular electrical stimulation (NMES) combined with a conventional rehabilitation program (CRP) on plantarflexor muscle spasticity and walking performance among individuals with chronic stroke. METHODS: A pilot randomized clinical trial (RCT) with two groups (active NMES and placebo) was conducted at the physical therapy departments of King Fahad Specialist Hospital, Buraydah, and Sultan Bin Abdulaziz Humanitarian City, Riyadh, Saudi Arabia (November 2020). The assessor and participants were blinded for the group assignment. The active NMES group received exercise and stimulation at the dorsiflexor muscles on the paretic leg for 30 min for 12 sessions. The placebo group received exercise and sham stimulation at the same position and duration as the active group. Of interest were the outcomes for plantarflexor muscle spasticity measured by the modified Ashworth scale (MAS), gait speed measured by 10 m walk test (10-MWT), and functional mobility measured by functional ambulatory category (FAC). RESULTS: Nineteen participants were randomized into active NMES (n = 10) and sham NMES (n = 9) groups, with no significant baseline differences. Within the active NMES group, significant improvements were observed in MAS (p = 0.008), 10-MWT (p = 0.028), and FAC (p = 0.046), while only 10-MWT time improved significantly in the sham NMES group (p = 0.011). Between-group analysis showed that only MAS was significantly lower in the active NMES group (p = 0.006). Percent change analysis indicated a significantly higher increase in percent change for MAS in the active NMES group compared to the sham NMES group (p = 0.035), with no significant differences in other outcome measures. CONCLUSIONS: This study showed that NMES in the active group led to significant improvements in spasticity, walking performance, and functional ambulation. Further research is needed to determine the ideal parameters, protocols, and patient selection criteria for NMES interventions in stroke rehabilitation.

Prevalence of falls among adult mothers in Saudi Arabia: a cross-sectional study.

BACKGROUND: The prevalence of falls among mothers (18-49 years old) in Saudi Arabia has been overlooked and understudied. Therefore, the study aimed to identify the 1-year prevalence, rate of falls, and consequent injuries among mothers in Saudi Arabia. METHODS: In this cross-sectional study, a self-administered online questionnaire, including sociodemographic data and questions related to the history of falls and consequent injuries during the past 12 months, was disseminated through social media in Saudi Arabia. RESULTS: A convenience sample of 986 mothers were voluntarily recruited for this study with a median age of 33 years and an interquartile range of 10 years. The 1-year prevalence of falls among mothers was 14.1 % (n = 139), and 52.5 % (n = 73/139) of the fallers experienced more than one fall. Among mothers who had experienced a fall, 25.4 % (n = 33/139) experienced a fall incident during pregnancy. The reported consequences of falls were pain in 37.4 % (n = 52/139), muscle and ligament injuries in 7.2 % (n = 10/139), and fractures in 2.2 % (n = 3/139) of participants. The study's findings indicate that asthma and high cholesterol level predicts the risk of falls in mothers. CONCLUSIONS: According to our convenience sampling, 14.1% of mothers had experienced one or more falls in the past 12 months. The increased prevalence of falls among this age group of women supports the idea that falls are not only an issue for the older adult population, but fall prevention strategies for this age range are also needed.

Effectiveness of Physical Exercise on Pain, Disability, Job Stress, and Quality of Life in Office Workers with Chronic Non-Specific Neck Pain: A Randomized Controlled Trial.

Neck pain is a widespread medical condition among office workers worldwide. This study aimed to compare physical exercises, including basic body awareness, neck-specific training exercises and ergonomic modifications, and ergonomic modifications alone in the management of chronic non-specific neck pain (NSNP) among office workers. Sixty participants were randomly allocated to an experimental group (physical exercises and ergonomic modifications) or a control group (ergonomic modifications) and received the intervention two times a week for eight weeks. The Numerical Pain Rating Scale, Neck Disability Index, Health and Safety Stress Tool, and Short Form Health Survey-36 were used to measure pain, disability, job stress, and quality of life at baseline, and at weeks 4 and 8 of the study period. A repeated measure ANOVA was used to determine the within-group significant differences and an independent t-test was utilized to compare group differences. The baseline data of the experimental and control groups showed no significant difference (p ≥ 0.05). The 2 × 3 mixed models ANOVA showed a significant difference in pain intensity (p = 0.001, ηp2 = 0.042), functional disability (p = 0.001, ηp2 = 0.052), work-related stress (p = 0.001, ηp2 = 0.036), and QoL (p = 0.012, ηp2 = 0.025). Four weeks post-intervention, the experimental group showed significant changes in primary (pain intensity and disability) (1.9; 95% confidence interval 1.65-2.14) and secondary (quality of life and work-related stress) outcomes (p < 0.001). The same gradual improvement in these variables was observed in the 8-week follow-up (p < 0.001). There was a significant improvement in clinical outcomes following the application of physical exercises with ergonomic modifications for chronic NSNP among office workers. This is significant for office workers because it suggests the importance of incorporating physical exercises into their daily routine and making ergonomic changes to their workspaces.

Effects of backward walking exercise using lower body positive pressure treadmill on knee symptoms and physical function in individuals with knee osteoarthritis: a protocol for RCT.

OBJECTIVES: The primary aim is to compare the effects of backward walking exercise to forward walking exercise on knee pain, knee functions, and thigh muscle strength in individuals with mild to moderate knee osteoarthritis using lower body positive pressure, in addition to mobility functions, balance, and self-reported health status. METHODS: The study is a single blind randomized clinical trial with two independent groups. This study will enroll 26 participants with mild to moderate knee osteoarthritis. The participants will be randomized into either experimental group (backward walking exercise) or control group (forward walking exercise). Both groups will use lower body positive pressure treadmill for walking exercise. Both groups will perform regular conventional exercise and worm-up exercise before walking exercise. The treatment will be three times a week for six weeks. Walking session will be up to 30 min each session. Data collection will be collected during pre- and post- intervention including primary outcomes including numeric pain rating scale (NPRS), knee injury and osteoarthritis outcome score (KOOS), and thigh muscle strength test. The secondary outcomes include five times sit to stand test (FTSTS), 3-meter backward walk test (3MBWT), timed up and go test (TUG), four square step test (FSST), functional reach test (FRT), 10-meter walk test (10-MWT), six minute walk test (6MWT), medical outcomes study short form 12 (SF-12), patient health questionnaire -9 (PHQ-9), and rapid assessment of physical activity (RAPA). An independent t-test will be used to evaluate the effect of treatment on the outcome measures. RESULTS: Not applicable. CONCLUSION: Using lower body positive pressure may have promising results against knee osteoarthritis. Moreover, walking backward exercise using lower body positive pressure might add more benefits to individuals with knee osteoarthritis and help clinicians in decision making. TRIAL REGISTRATION: This study was registered in ClinicalTrails.gov (ID: NCT05585099).

The Safety and Feasibility of Lower Body Positive Pressure Treadmill Training in Individuals with Chronic Stroke: An Exploratory Study.

BACKGROUND: Lower body positive pressure (LBPP) may provide a novel intervention for gait training in neurological conditions. Nonetheless, studies investigating the safety and feasibility of LBPP in patients with stroke are insufficient. OBJECTIVES: The purpose of this study was to evaluate the safety and feasibility of LBPP as a rehabilitation intervention for individuals with chronic stroke. METHODS: Individuals with chronic stroke were recruited from the community to participate in LBPP gait training three times a week for six weeks. The LBPP's safety and feasibility were documented throughout the study and at the end of six weeks. Safety and feasibility referred to the incidence of adverse events, complications, the participant and therapist satisfaction questionnaire, and the device limitation including but not limited to technical issues and physical constraints. In addition, blood pressure, pulse rate, and oxygen saturation were taken pre- and post-session. Dependent t-tests were used to analyze the difference between assessments. A Wilcoxon test was used to assess the ordinal data (Trial registration number NCT04767334). RESULTS: Nine individuals (one female, eight males) aged 57 ± 15.4 years were enrolled. All participants completed the intervention without adverse events. All participants reported positive scores from 4 (very satisfying) to 5 (extremely satisfying) in the safety and feasibility questionnaire. No significant differences were observed in blood pressure and oxygen saturation during the intervention sessions. However, significant increases were observed in heart rate from 82.6 ± 9.1 beats/min (pre-session) to 88.1 ± 6.8 beats/min (post-session) (p = 0.027). CONCLUSIONS: LBPP is a safe and feasible rehabilitation tool to use with individuals with chronic stroke.

Effects of Neuromuscular Electrical Stimulation on Plantarflexors Spasticity, Gait Performance, and Self-Reported Health Outcomes in People With Chronic Stroke: A Study Protocol for a Double-Blinded Randomized Clinical Trial.

Introduction: Rehabilitation approaches have been used for people with stroke to decrease spasticity and improve functions, but little is known about the effect of neuromuscular electrical stimulation (NMES) in this population. Therefore, the primary purpose of this study was to establish a protocol for a double-blinded randomized clinical trial to examine using NMES on plantarflexors spasticity, dorsiflexor muscle strength, physical functions, and self-reported health outcomes in people with chronic stroke in Saudi Arabia. Material and Methods: This randomized clinical trial with two arms and double-blinded registered in ClinicalTrials (NCT04673045) will enroll 44 participants with chronic stroke and randomized them into either the experimental group (EG), including electrical stimulation (ES) with conventional therapy or the control sham group (NMESsham) including placebo electrical stimulation with conventional therapy. The frequency will be set at 80 Hz for 30 min. The intervention will be three times a week for 4 weeks for both groups. Data collection for pre- and post-intervention outcomes will include measurements for the primary outcomes including paretic limb (plantarflexor spasticity, ankle range of motion, and dorsiflexor muscles strength), and gait speed using 10-m walk test (10-MWT). The secondary outcomes including mobility function using Timed Up and Go (TUG), walking endurance using 6 Minutes Walk Test (6-MWT), activity of daily living using the Arabic version of Barthel Index (BI), and self-reported health measures such as quality of life using the Medical Outcomes Survey (Short Form 36, SF-36), physical activity using Rapid Assessment of Physical Activity (RAPA), depression symptoms using Patient Health Questionnaire-9 (PHQ-9), fatigue level using Fatigue Severity Scale (FSS), and risk of fall using Fall Efficacy Scale International (FES-I). An independent t-test will be utilized to examine the effect of the intervention on the outcome measures. Results: The recruitment has started and is ongoing. Conclusions: Using 4 weeks of NMES will provide information about its effect in improving plantarflexor spasticity, dorsiflexor muscles strength, gait speed, mobility functions, and other self-reported health outcomes in people with chronic stroke when compared to NMESsham.

Walking with and without a robotic exoskeleton in people with incomplete spinal cord injury compared to a typical gait pattern.

BACKGROUND: Robotic exoskeleton (RE) enables individuals with lower extremity weakness or paralysis to stand and walk in a stereotypical pattern. OBJECTIVE: Examine whether people with chronic incomplete spinal cord injury (SCI) demonstrate a more typical gait pattern when walking overground in a RE than when walking without. METHODS: Motion analysis system synchronized with a surface electromyographic (EMG) was used to obtain temporospatial gait parameters, lower extremity kinematics, and muscle activity in ambulatory individuals with SCI and healthy adults. RESULTS: Temporospatial parameters and kinematics for participants with SCI (n = 12; age 41.4±12.5 years) with and without RE were significantly different than a typical gait (healthy adults: n = 15; age 26.2±8.3 years). EMG amplitudes during the stance phase of a typical gait were similar to those with SCI with and without RE, except the right rectus femoris (p = 0.005) and left gluteus medius (p = 0.014) when participants with SCI walked with RE. EMG amplitudes of participants with SCI during the swing phase were significantly greater compared to those of a typical gait, except for left medial hamstring with (p = 0.025) and without (p = 0.196) RE. CONCLUSIONS: First-time walking in a RE does not appear to produce a typical gait pattern in people with incomplete SCI.

The Extent of Commitment of Saudis During Holy Ramadan to Social Distancing Measures Required for the Prevention of Transmission of COVID-19.

Coronavirus disease (hereafter COVID-19) was declared a pandemic by the World Health Organization (WHO) in March 2020. People were admitted to hospitals complaining of fever, fatigue, cough, and difficulty breathing. Consequently, the strategy being adopted to limit the spread of COVID-19 is to encourage people in society to follow preventive measures. We aimed to estimate how the knowledge of and compliance with safe distancing measures affected the progression of the COVID-19 pandemic in Saudi Arabia during Holy Ramadan. A cross-sectional survey was implemented in the central regions of Saudi Arabia from 24th of April to 22nd May to coincide with Ramadan. The study was conducted using a Google forum distributed through social media. Participants were recruited through convenience sampling of the Saudi population. In total, 1515 participants completed the survey. A significant difference between males and females was observed in answering questions about committing to: not attending gatherings, keeping a safe distance, not making physical contact, and staying at home during partial lockdown. In general, participants in our study demonstrated excellent adherence to all social distance measures, considered essential for limiting the spread and progression of COVID-19. However, attitudes regarding reduced physical contact was poor in the Makkah region, which necessitates greater efforts to educate and inform people about the associated risks.

Immediate kinematic and muscle activity changes after a single robotic exoskeleton walking session post-stroke.

Background: Robotic Exoskeletons (EKSO) are novel technology for retraining common gait dysfunction in people post-stroke. EKSO's capability to influence gait characteristics post-stroke is unknown. Objectives: To compare temporospatial, kinematic, and muscle activity gait characteristics before and after a single EKSO session and examine kinematic symmetry between involved and uninvolved limbs. Methods: Participants post-stroke walked under two conditions: pre-EKSO, and immediately post-EKSO. A 10-camera motion capture system synchronized with 6 force plates was used to obtain temporospatial and kinematic gait characteristics from 5 walking trials of 9 meters at a self-selected speed. Surface EMG activity was obtained from bilateral gluteus medius, rectus femoris, medial hamstrings, tibialis anterior, and soleus muscles. Wilcoxon Signed Rank tests were used to analyze differences pre- and post-EKSO. Single EKSO session consisted of 22.3±6.8 minutes total time (walk time=7.2±1.5 minutes) with 250±40 steps. Results: Six ambulatory (Functional Ambulation Category, range=4-5) adults (3 female; 44.7±14.6 years) with chronic stroke (4.5±1.9 years post-stroke) participated. No significant differences were observed for temporospatial gait characteristics. Muscle activity was significantly less post-EKSO in the involved leg rectus femoris during swing phase (p=0.028). Ankle dorsiflexion range of motion on the involved leg post-EKSO was significantly less during stance phase (p=0.046). Differences between involved and uninvolved joint range of motion symmetry were found pre-EKSO but not post-EKSO in swing phase hip flexion and stance phase knee flexion and knee extension. Conclusions: EKSO training appears capable of altering gait in people with chronic stroke and a viable intervention to reduce gait dysfunction post-stroke.

Walking With a Robotic Exoskeleton Does Not Mimic Natural Gait: A Within-Subjects Study.

BACKGROUND: Robotic exoskeleton devices enable individuals with lower extremity weakness to stand up and walk over ground with full weight-bearing and reciprocal gait. Limited information is available on how a robotic exoskeleton affects gait characteristics. OBJECTIVE: The purpose of this study was to examine whether wearing a robotic exoskeleton affects temporospatial parameters, kinematics, and muscle activity during gait. METHODS: The study was completed by 15 healthy adults (mean age 26.2 [SD 8.3] years; 6 males, 9 females). Each participant performed walking under 2 conditions: with and without wearing a robotic exoskeleton (EKSO). A 10-camera motion analysis system synchronized with 6 force plates and a surface electromyography (EMG) system captured temporospatial and kinematic gait parameters and lower extremity muscle activity. For each condition, data for 5 walking trials were collected and included for analysis. RESULTS: Differences were observed between the 2 conditions in temporospatial gait parameters of speed, stride length, and double-limb support time. When wearing EKSO, hip and ankle range of motion (ROM) were reduced and knee ROM increased during the stance phase. However, during the swing phase, knee and ankle ROM were reduced when wearing the exoskeleton bionic suit. When wearing EKSO, EMG activity decreased bilaterally in the stance phase for all muscle groups of the lower extremities and in the swing phase for the distal muscle groups (tibialis anterior and soleus) as well as the left medial hamstrings. CONCLUSIONS: Wearing EKSO altered temporospatial gait parameters, lower extremity kinematics, and muscle activity during gait in healthy adults. EKSO appears to promote a type of gait that is disparate from normal gait in first-time users. More research is needed to determine the impact on gait training with EKSO in people with gait impairments.

Proposing Development and Utility of a Mobility Composite Measure in Patients with a Neurologic Disorder.

BACKGROUND: Outcome measures typically assess single domains making holistic assessment difficult. Our purpose was to develop a mobility composite measure (MCM) based on four commonly used outcome measures and compare this composite score to the individual measures in patients with neurologic disorders. METHODS: We retrospectively reviewed 148 medical records for inclusion of primary neurologic diagnosis and scoring for 5 times sit-to-stand test (5TSST), 10-meter walk test (10MWT), 2-minute walk test (2MWT), and activities-specific balance confidence (ABC) scale. RESULTS: After establishing that a single concept was being assessed with interitem correlations, raw scores were converted to percentage of normal and combined into the MCM for analysis from admission to discharge. Scores on each measure significantly improved after intervention (5TSST, p < .001; 10MWT, p < .001; 2MWT, p < .001; ABC, p = .02). Mean MCM (n = 93) admission scores were 67.55 ± 31.88% and discharge scores were 74.81 ± 34.39% (p = .002). On average, patients improved 7.26% on the MCM exceeding the threshold of expected error (MDC95 = 3.59%). CONCLUSIONS: MCM detected change in patient outcomes statistically and clinically and appears to capture a holistic picture of functional status. We recommend a prospective study to further investigate a "composite measure" incorporating measures from several functional domains.
