Background: Female university students frequently complain of computer-related neck pain after one hour of use, which may cause changes in grip strength and nerve tension in the upper extremity.
Objective: The purpose of this study was to compare neck pain intensity, grip strength and upper limb neural tension, before and after an hour of computer use between female students with and without neck pain.
Method: There were 36 female students recruited, which were then divided into the neck pain group (n = 18) and the asymptomatic group (n = 18). Pain intensity, hand grip strength, and neurodynamic testing of the upper extremity were evaluated before and after typing a document on a computer for one hour.
Results: There was an increase in neck pain, a decrease in grip strength, and an increase in nerve tension of the median, radial, and ulnar nerves after computer use. However, when comparing between groups, the neck pain group had a significantly greater increase in the tension of only the right median and left ulnar nerves compared to the asymptomatic group.
Conclusion: The current findings demonstrated that an hour spent on a computer can increase neck pain, reduce grip strength, and produce neural tension of upper extremities. However, female students with neck pain had greater increase tension within the median and ulnar nerves, which may result in upper extremity impairment.

Respiratory muscle training reduces painful swallowing and opioid use during radiation therapy for head and neck cancer: a matched pair analysis.

Dept. Radiation Medicine, Roswell Park Comprehensive Cancer Center, Buffalo, USA.
Background: Patients with head and neck cancer (HNC) receiving radiation therapy (RT) are at increased risk for symptoms of oral mucositis (OM), opioid use, and declines in physical function, outcomes that contribute to increased morbidity and mortality. The study objective was to determine the effects of respiratory muscle training (RMT) on OM and opioid use, as well as functional performance in patients with HNC receiving RT with or without concurrent chemotherapy (CCRT).
Methods: Patients aged ≥ 18 years of age with stage I to IV HNC being treated with RT or CCRT receiving a home-based respiratory muscle training (RMT) (n = 20) were compared to a 5:1 matched historical group (n = 100) who did not receive RMT.
