Correlation between hand grip strength and functional mobility in elderly patients

Prognostic significance of skeletal muscle mass in patients with alcohol-related cirrhosis.

Muscle strength is the ability of muscles to produce power for physical activity, important for mobility, balance and body function. Decreased muscle strength, especially due to aging, negatively impacts quality of life and increases the risk of diseases such as diabetes and cardiovascular disease. Handgrip is a simple method for measuring muscle strength, especially hand grip strength. This study aims to evaluate the relationship between hand grip strength and blood insulin levels in the elderly. This study used a cross-sectional design at the Bina Bhakti Nursing Home with 93 participants aged 60 years and over. Hand grip strength was measured using a dynamometer, and blood insulin levels were measured from venous blood samples. Data were analyzed using Spearman correlation. The results showed an average right hand grip strength of 10.23 kg and left hand 9.33 kg, with an average blood insulin level of 4.83 µU/mL. A significant positive correlation was found between right and left hand grip strength (rho = 0.884, p < 0.001), as well as between right (rho = 0.218, p = 0.036) and left hand grip strength (rho = 0.290, p = 0.005) and insulin levels. blood. These results indicate that hand grip strength can be an indicator of metabolic health in the elderly. Interventions such as strength training and proper nutrition are important for maintaining muscle strength and metabolic health in the elderly.

BackgroundThere is limited information on the relationship between muscle strength and recurrence and mortality after incident venous thromboembolism (VTE). ObjectivesTo investigate whether weak hand grip strength (HGS) was associated with risk of recurrence and mortality in patients with VTE recruited from the general population. MethodsParticipants from the Tromsø Study with a first-time VTE (n = 545) were included, and all VTE recurrences and deaths among the participants were recorded in the period 1994 to 2020. Weak HGS was defined as lowest 25th percentile of the general population, and incidence rates for VTE recurrence and mortality according to weak vs normal (>25th percentile) HGS, with 95% CIs, were estimated. ResultsThere were 90 recurrences and 350 deaths during a median of 3.7 years of follow-up. The fully adjusted hazard ratio (HR) for overall VTE recurrence for those with weak HGS vs those with normal HGS was 2.02 (95% CI, 1.23-3.30). The corresponding HRs for recurrence were 2.22 (95% CI, 1.18-4.17) in patients with a first deep vein thrombosis and 1.60 (95% CI, 0.72-3.57) in patients with a first pulmonary embolism. The cumulative 1-year survival was 74.9% and 77.8% in those with weak and normal HGS, respectively. For overall mortality after incident VTE, the fully adjusted HR for those with weak HGS was 1.34 (95% CI, 1.04-1.72). ConclusionWeak HGS was associated with an increased risk of recurrent VTE, and the association appeared to be particularly pronounced after incident deep vein thrombosis. There was a slightly lower survival probability among those with weak HGS than among those with normal HGS.

BackgroundHallux valgus, lesser toe deformity, and muscle weakness of the toe flexors contribute to falls in older people. This study aimed to examine the differences in toe flexor strength and foot morphology in older people requiring long-term care due to changes in the way they mobilize in everyday life.MethodsThis study included 84 people aged ≥70 years without motor paralysis who underwent rehabilitation. They were divided into those who could mobilize without a wheelchair (walking group, n = 54) and those who used a wheelchair to mobilize (wheelchair group, n = 30). The presence or absence of diseases was confirmed, and hand grip strength, toe flexor strength, and foot morphology using the foot printer were measured. The presence of diseases, hand grip strength, toe flexor strength, and foot morphology were compared between the two groups. Multiple logistic analysis was performed with wheelchair dependence as the dichotomous outcome variable, and the percentages of each strength measure observed in the wheelchair group to the average hand grip and toe flexor strength measures in the walking group were compared.ResultsNo significant between-group difference in foot morphology was found. The factors related to the differences in ways of ambulating in daily life were history of fracture, heart disease, and toe flexor strength. After comparing the muscle strength of the wheelchair group with the mean values of the walking group, we found that the toe flexor strength was significantly lower than the hand grip strength.ConclusionsOlder people who used a wheelchair to mobilize have significantly less toe flexor strength than those who do not despite no significant difference in foot morphology. Use of a wheelchair is associated with a reduction in toe flexor strength.

Measurement of grip strength is an important component in hand evaluation. It assesses the patient's initial limitations and provides a quick reassessment of patient's progress throughout the treatment. This investigation was conducted to examine the determinants of hand dominance of average versus maximum grip strength, body mass index (BMI) and age for hand evaluation. Subjects were 877 apparently healthy male adult volunteers from the Inonu University – students and personnel; average age 21.14±2.09(19–40 years). A good correlation was found between the BMI hand strength measures. Grip strength was measured instrumentally. The rule "dominant hand(DH) is approximately 10% stronger than the non-dominant hand (NDH)" was found to be valid for left handed persons only (7%) otherwise these measures should be considered equivalent in both hands. The difference between maximum and average of three consecutive measurement of grip strength was found significant for both hands. As the significant difference was found between RGSmax (Maximum Grip Strength of Right Hand) and RGSav (Average Grip Strength of Right Hand); LGSmax (Maximum Grip Strength of Left Hand)/LGSav (Average Grip Strength of Left Hand) measures for RDH. RGSmax and LGSmax where correlated only for LDH. Therefore, average of three consecutive measurement of grip strength is more consistent for standard hand evaluation.

Although many studies have shown that p16INK4a is more highly expressed in the human body during senescence, studies on its relevance to handgrip strength among old adults, are relatively sparse. We enrolled 205 community-dwelling old adults aged 65 years and older without specific medical conditions. Handgrip strength of the dominant hand was measured. Low handgrip strength was defined as the lowest quartile of handgrip strength among the participants. RNA was extracted from peripheral white blood cells. Use quantitative polymerase chain reaction to estimate the p16INK4a mRNA expression level. The average handgrip strength was 25.22 ± 8.98 kg, and gender difference was observed. In the linear regression model, the p16INK4a mRNA expression level was significantly negatively associated with handgrip strength in men but not in women. The β coefficient, representing the change of handgrip strength for each increment in the p16INK4a mRNA expression level, was −0.208 (p = 0.024) among old men. The negative association remained after additional covariates adjustment. In the multiple logistic regression model among old men, the odds ratio (OR) of low handgrip strength was 1.246 (p = 0.032). In this study, we observed the p16INK4a mRNA expression level was negative associated with handgrip strength among community-dwelling old men.

The objective of this study is to examine the relationship among anthropometric dimensions, grip span, discomfort, gender, and grip strength. The 24 volunteer subjects (12 males, 12 females) performed five grips squeezing their hardest for 2 minutes at each of the five grip spans on the Jamar grip dynamometer. The grip strength was recorded using the UPC software and then averaged for each of the 30 second intervals. The data was analyzed using ANOVA, post-hoc (Tukey) hypothesis tests, and regression. In the ANOVA analysis gender, grip span, time, and the interactions of gender-grip span, grip span-time, and time-gender were determined to be the significant effects. In all four of the 30 second intervals, average grip strength was significantly higher for males than females. Female average grip strength was found to be 70% of male average grip strength. The post-hoc (Tukey) tests showed that grip spans 3, 4, and 2 were significantly higher than grip spans 5 and 1. The anthropometry of several segments of the hand were found to be important predictors of grip strength and discomfort in the stepwise regressions. Grip span 4 had the highest average severity of discomfort, while grip span 1 had the most areas of the hand experiencing discomfort.

Modified Five-item Frailty Index (mFI-5) versus Grip Strength as predictors of length of stay, discharge to home, and early surgical complications in patients undergoing long segment fusion.

Grip strength is a key indicator of muscle function and health in elderly women, influencing mobility and independence. Factors such as blood pressure, body composition, and metabolic biomarkers influence grip strength. This study examines the relationship between blood pressure, anthropometric measurements, hemoglobin, hematocrit, blood sugar, and uric acid with grip strength. A cross-sectional study was conducted on 34 elderly women (mean age: 72.24 years) in the St. Asisi Elderly Community, Tebet. Blood pressure, anthropometric parameters, and venous blood samples were analyzed. Grip strength was assessed using the Camry Electronic Hand Dynamometer. Statistical analysis used the Spearman correlation test (p < 0.05). Age showed a significant negative correlation with right-hand (p = 0.023) and average grip strength (p = 0.026), indicating muscle decline with age. Other factors, including blood pressure, hemoglobin, hematocrit, blood sugar, and uric acid, had no significant correlations. Among anthropometric measures, calf circumference showed the strongest positive correlation with grip strength (p = 0.063). Age is the primary factor affecting grip strength in elderly women, with weak or no significant associations for other parameters. Strength training and neuromuscular conditioning may help mitigate age-related muscle decline and support functional independence.

Equivalent to a human triathlon, combined driving is an equestrian sport designed to test ability to navigate horses and carriage during three phases. Drivers control up to four horses at a time relying heavily on hand strength. PURPOSE: to 1) establish baseline data on grip strength and endurance of combined drivers in standing and task-specific positions; and 2) compare grip values to normative data by driver age. METHODS: Drivers were included if medically cleared to actively compete, and free from current injury. Fifty-one combined drivers (9 males, 42 females) ages 21-78 participated during two nationally recognized events. All drivers were right hand dominant. 63% of drivers were over 50 y/o. 22% of drivers reported having arthritis in their hands/wrists. Drivers completed a demographics and sport-specific survey, and three grip tests in two positions: standing and task-specific (sitting). Measures included peak values and endurance. Peak grip was recorded into four categories based on normative values. RESULTS: Females with more than 30 yrs of driving experience had higher strength in the non-dominant hand (p=0.0345). There was a significant difference between strength based on position for both sexes (Table 1). Over 45% of females were stronger than normative data for both dominant and non-dominant hand, while only 22% of males fell in the stronger category. Female drivers average hand grip strength was 1.25 times greater than the normative population. The endurance for all subjects was significantly higher for the right hand (p=0.002). CONCLUSIONS: This study is the first to establish standing and task-specific grip strength in combined drivers. Female drivers over 50 y/o demonstrated greater hand strength in their non-dominant hand, suggesting continuous use of hands for driving promotes strengthening muscle and maintaining hand function regardless of reported arthritis. Results demonstrated equestrian driving is beneficial to hand grip strength.

Cerebral palsy is a neurodevelopmental condition that results in impaired movement and posture, often accompanied by disturbances in balance and functional abilities. Recent advances in neurorehabilitation, including whole-body vibration therapy (WBVT), functional electrical stimulation, and transcranial direct current stimulation, show promise in enhancing traditional interventions and fostering neuroplasticity. However, the efficacy of their conjunct effects remains largely uncharted territory and warrants further exploration. The objective of the study was to compare the conjunct effects of functional electrical stimulation (FES) and WBVT with transcranial direct current stimulation (tDCS) and WBVT on lower extremity range of motion (ROM), dynamic balance, functional mobility, isometric muscle strength and hand grip strength in children with spastic cerebral palsy. A randomized clinical trial was carried out on 42 children of both genders with spastic cerebral palsy, aged 5-15 years. The childrenwere dividedat random into three groups (14 in each group).In Group A, there were three (21.42%) males and 11 (78.57%) females, in Group B, eight (57.14%) were males and six (42.85%) were females, and in Group C, six (42.85%) children were males and eight (57.14%) were females. Group A received WBVT only, Group B received WBVT and FES, and Group C received WBVT and tDCS. The intervention was applied four times a week for four consecutive weeks. The data was collected two times before and immediatelyafter four weeks of intervention. Lower extremity ROM was measured by a goniometer, functional mobility or dynamic balance was measured by a Time Up and Go test, isometric muscle strength was measured by a digital force gauge, and hand grip strength was assessed by a digital hand-held dynamometer. IBM SPSS Statistics for Windows, Version 27.0 (Released 2020; IBM Corp., Armonk, New York, United States) was utilized for statistical analysis. The mean age of the children in groups A, B, and C was 12.21±2.11 years, 11.71±2.01, and 11.07±2.01 years respectively. Intergroup analysis revealed a statistically significant difference (p<0.05) in the lower extremity range of motion, and functional mobility. Hand grip strength and isometric muscle strength between three groups. Post hoc analysis revealed that WBVT with transcranial direct current stimulation combined showed the most improvement. The study concluded that positive effects were seen in all three groups but tDCS with WBVT was found to be most effective in improving lower extremity ROM, functional mobility or dynamic balance, isometric muscle strength, and hand grip strength in children with spastic CP. The differences between the groups were statistically significant. The effect size was substantial enough to surpass established clinical benchmarks, indicating that the observed improvements are likely to have meaningful and beneficial impacts on patient outcomes.

Open Reduction and Internal Locked Fixation of Unstable Distal Ulna Fractures With Concomitant Distal Radius Fracture

Background The aging process results in physiological changes in the body, such as decreased muscle strength and impaired balance, so that the risk of falls, injury and dependency increases in the elderly. Changes in the nutritional status of the elderly who tend to be predominantly underweight also occur due to the aging process and have an impact on the muscle strength of the elderly in the long term. This study aims to determine the relationship between BMI and hand grip strength in the elderly at PSTW Sabai Nan Aluih Sicincin. Methods This study is an analytical and secondary research with a cross-sectional design, involving 62 elderly individuals from PSTW Sabai Nan Aluih Sicincin as the population. All population members meeting the inclusion criteria and excluding outliers were considered as the research sample. The inclusion criteria encompassed complete data such as BMI, handgrip strength, age, weight, knee height, and gender. Two outlier samples were excluded based on the exclusion criteria. Bivariate data analysis utilized the Chi-square statistical test. Results The research findings indicate that most elderly women at PSTW Sabai Nan Aluih Sicincin have normal to overweight BMI, while elderly men have underweight BMI. Elderly women at PSTW Sabai Nan Aluih Sicincin exhibit abnormal handgrip strength, whereas elderly men have normal handgrip strength. Furthermore, there is no significant relationship (p=0.676) between BMI and handgrip strength values among the elderly at PSTW Sabai Nan Aluih Sicincin. Conclusions This study concluded that there was no significant relationship between BMI and hand grip strength scores in the elderly at PSTW Sabai Nan Aluih Sicincin.
