The relationship between smartphone usage duration (using smartphone’s ability to monitor screen time) with hand-grip and pinch-grip strength among young people: an observational study

Abstract Background The use of smartphones has become widely popular, especially among young people, for multiple purposes other than communication, including gaming and internet browsing. The hand and wrist weakness is one of the main complications associated with the increased use of smartphones. This weakness occurs due to the repetitive flexion and extension of the wrist, thumb, and fingers, leading to a significant musculoskeletal pathology. Little is known about the relationship between smartphone usage duration (using the phones ability to monitor screen time) and hand-grip, pinch-grip strength. Therefore, the study was aimed to investigate the association between smartphone usage duration and hand-grip, pinch-grip strength among young people. Methods One hundred young males volunteered to participate in the study. Participants were briefly examined for height and weight using a portable stadiometer and a digital scale. Hand-grip, pinch-grip strength measurement was performed using a hand-held dynamometer. Smartphones usage duration was obtained from the daily average screen time reported in the last seven days. Results Mean daily usage of smartphone among the participants was 7.8 ± 2.2. There was a weak significant inverse relationship between smartphone usage duration and hand-grip strength (r=-.22, p = .03) and pinch-grip strength (r=-.28, p = .004). Linear regression revealed that 18.8 % of the variance in hand-grip strength and 20.4 % of the variance in pinch-grip strength was explained by age, and smartphone usage duration, with the addition of BMI only to hand-grip strength (p’s < 0.00). Conclusions Prolonged use of smartphones was related to weaker hand-grip and pinch-grip. Despite the weak relationship, the study showed that smartphone usage duration might contribute as a factor along with age to hand muscles’ strength.

Abstract BackgroundThe use of smartphones has become widely popular especially among young people for multiple purposes other than communication including gaming and internet browsing. The weakness of the hand and wrist is one of the main complications associated with the increase of use of smartphones. This weakness occurs due to the repetitive flexion and extension of the wrist, thumb and fingers which eventually could lead to a major musculoskeletal pathology. Little is known about the relationship between smartphone usage duration (using the phones ability to monitor screen time) and hand-grip, pinch-grip strength. Therefore, the study was aimed to investigate the association between smartphone usage duration and hand-grip, pinch-grip strength among young people. Methods100 young males volunteered to participate in the study. Participants were briefly examined for height and weight using a portable stadiometer and a digital scale. Hand-grip, pinch-grip strength measurement was performed using a hand-held dynamometer. Smartphones usage duration was obtained from the daily average screen time reported in the last seven days. ResultsMean daily usage of smartphone among the participants was 7.8 ± 2.2. There was a significant inverse relationship between smartphone usage duration and hand-grip strength (r=-.22, p=.03) and pinch-grip strength (r=-.28, p=.004). ConclusionProlonged use of smartphones is related to weaker hand-grip and pinch-grip. This may lead to future musculoskeletal pathologies such as carpal tunnel syndrome. Young people should be aware of the dangers of smartphones overuse.

The index finger and the 4th finger ratio (2D:4D) is the indicator of the prenatal testosterone. The aim of this study is to investigate the relationship between 2D:4D, hand preference and hand grip strength in swimmers. A total of 80 elite swimmers, participated in the study. Height, body weight, body mass index (BMI), hand 2D:4D finger measurements and hand grip strength tests were performed for athletes. The hand preference was determined by the Oldfield questionnaire and it was evaluated according to the Geschwind score. The data were recorded in the SPSS 20 program and p<0.05 was considered as statistically significant. It was found that in both men and women, a negative correlation was found between right and left hand 2D:4D and both dominant (DHGS) and non-dominant hand grip strength (NDHGS) values. It was found that men had lower 2D:4D ratio than women. For both right and left handed, there was a statistically significant difference between the right and left hand 2D:4D ratios in both men and women (p<0.05) and the dominant hand (DH) 2D:4D ratios were found to be lower than non-dominant hand (NDH) 2D:4D ratios in both men and women (p<0.05) It can be said that the 2D:4D ratios may be the effect of determining the hand preference, the grip strength and therefore the strength.

Hand Grip

The performance of competition climbers in laboratory-based tests of pinch and whole hand grip strength and endurance was compared to that of non-climbers of the same age, sex and physique. Climbers performed significantly better, indicating higher stresses acting in the flexor mechanism, possibly predisposing injury. Attempts were made to correlate the performance in the tests to climbing achievement, measured by current technical climbing standards. Although pinch grip strength increased with the length of climbing experience, there was no evidence that strength in the hands alone guarantees success in competition climbing.
