Supermarket cashiers face a significant amount of stress, including time constraints, mental pressure, and physical demands that require repetitive movements. The job description of a supermarket cashier involves work-related risk factors that may lead to musculoskeletal disorder (MSD) symptoms. This study aimed to investigate supermarket cashiers to determine the prevalence of MSD symptoms and their quality of life. Data were collected from a convenience sample of supermarket cashiers working in Saudi Arabia. Information included direct questions on pain in the previous 12 months, demographic data, and health- or occupation-related factors. Moreover, data was collected based on the 36-item short form survey (SF-36), and descriptive statistics were computed. A total of 193 supermarket cashiers participated in this study. The sample included 140 men (72.5%) and 53 women (27.5%), with a mean age of 27.2 ± 6.4 years. The majority of the participants (90%) had MSD symptoms in at least one body region, with the neck (66.84%) and lower back (65.80%) constituting the most prominent regions. The mean SF-36 scores were higher in participants without pain compared to participants with pain in all domains, except for the physical functioning domain. The high prevalence of MSD symptoms among young cashiers suggest the need for additional investigations to determine the risk factors of these disorders. Additionally, this study recommends preventive procedures to reduce the prevalence of MSD symptoms among cashiers.

Purpose. Cervical radiculopathy is disorder of cervical spinal nerve root affecting large number of population. Previously many studies are conducted to design suitable protocol for management of this disorder, but they lack in quality. The purpose of this study was to compare the effects of neural mobilization and cervical isometrics on health‐related quality of life and deep flexors endurance in cervical radiculopathy. Methods. A double‐blinded randomized clinical trial was conducted at Mayo Hospital, Lahore, Pakistan. Eighty‐eight patients within the age range of 35‐50 years were included in the study after taking their consent. In the experimental group (n = 44), median nerve mobilization was applied along with cervical isometric exercises. The control group (n = 44) performed cervical isometric exercises alone. Muscle endurance was measured by craniocervical flexion test and quality of life on 36 items short form health survey SF‐36 scale. Measurements were taken at baseline, at 2nd week, and at 4th week. For missing data, intention‐to‐treat analysis was used. Results. Within‐group comparison with Friedman test showed a significant difference between pre, mid, and posttreatment scores on craniocervical flexion test and in all domains of SF 36 in both groups. While between‐group comparison with Mann–Whitney U test showed all variables were similar at baseline but after 4 weeks there was a statistically significant improvement in craniocervical flexion test scores and all domains of SF 36 in the experimental group. But domain of pain showed mean rank of 49.43 after 4 weeks in the experimental group and 39.57 in the control group with p = 0.065 and d = 0.579, while for all the other 7 domains values were p < .05 and d > 0.25. Conclusion. Neural mobilization combined with cervical isometrics shows significant effects in improving quality of life and deep flexors endurance in patients with cervical radiculopathy than cervical isometrics alone.

Impaired vision is one of the commonest and most disabling consequence following stroke. Among all visual impairments, eye movement disorders are found in 70% of stroke patients which include nystagmus, strabismus, gaze palsies, disconjugate eye movements and cranial nerve palsies. They have a wide ranging impact on balance and activities of daily livings by creating difficulties in maintaining normal alignment and appropriate movement of eyes. The purpose of this study was to examine the effects of visual scanning exercises in addition to task specific approach on balance and activities of daily livings in post stroke patients with eye movement disorders. This study is a randomized controlled trial and was conducted in the University of Lahore Teaching Hospital from May 2019 to October 2020. A sample of 64 patients was recruited and randomly allocated into experimental and control group. 32 patients in experimental group were treated with visual scanning exercises along with task specific approach and 32 patients in control group were treated with task specific approach alone. Pre and post assessment of balance and activities of daily livings was assessed on BERG BALANCE SCALE and BARTHEL INDEX SCALE at baseline and at 4th week. Intra-group analysis of BERG BALANCE SCALE in experimental group showed statistically significant result (p < 0.05) in all items except in items 4, 13 and 14 respectively. Intra-group analysis of BERG BALANCE SCALE in control group showed statistically significant result (p < 0.05) in items 3, 5, 8 and 12 respectively, whereas remaining all items showed statistically insignificant result. Intra-group analysis of BARTHEL INDEX SCALE in experimental group showed statistically significant result in all items (p < 0.05) except in items 9 and 10 respectively. Intra-group analysis of BARTHEL INDEX in control group showed statistically significant result (p < 0.05) in items 1, 3, 4 and 8 respectively whereas remaining all items showed statistically insignificant result. Inter-group analysis showed statistically significant result in total scores of BERG BALANCE SCALE (p = 0.000) and BARTHEL INEX SCALE (p = 0.033). Visual scanning exercises along with task specific approach were found to be more effective in comparison to task specific approach alone.

Background and Objectives: It has been seen that jaw opening is associated with neck extension and jaw closing is associated with neck flexion. This natural association between the jaw and neck can be used as a novel approach to treat chronic non-specific neck pain, although the effects of this concept have never been previously evaluated as a treatment strategy. This article intends to study the effects of integrating jaw opening and closing movements along with active neck exercises versus active neck exercises alone in the management of chronic non-specific neck pain. Materials and Methods: A total of 80 patients, aged 20 to 50, with chronic non-specific neck pain were included in a double-blind randomized controlled trial, conducted at the Sindh Institute of Physical Medicine and Rehabilitation, Karachi, Pakistan from 2018 to 2022. The patients were divided into two groups: Group A patients were assigned jaw movements with active neck exercises, while Group B patients were assigned only active neck exercises. Both groups were assigned isometric strengthening exercises and self-resisted strengthening exercises for cervical spine muscles as a home plan. The study used various outcome measures, including the numerical pain rating scale (NPRS), neck disability index (NDI), neck flexion endurance (NFE), neck extension endurance (NEE), the neck proprioception error (NPE): neck flexion proprioception error (NFPE), neck extension proprioception error (NEPE), neck right rotation proprioception error (NRRPE), and neck left rotation proprioception error (NLRPE), with measurements taken at week 1 and week 6, respectively; the mean differences between the groups were measured using a two-way repeated ANOVA. Results: The experimental group showed better improvements compared to the control group, NPRS (73%), NDI (57%), NFE (152%), NEE (83%), NFPE (58%), NEPE (65%), NRRPE (65%), and NLRPE (62%), with a significant difference (p < 0.05). Conclusions: Active neck extension and flexion movements combined with jaw opening and closing are more effective in reducing pain and disability, improving neck muscles endurance and normalizing neck proprioception in patients with chronic neck pain.
