Objective: The objective of this study is to investigate the effect grip strength in different positions of elbow with shoulder neutral and flexion while the subject is in standing position. Methods: 30 students from the Vinayaka Mission College of physiotherapy were selected randomly with the age group of 18-25years and divided into group 1 (n=15) male and group 2 (n=15) female. Testing done in standing posture, the right handed dominant subjects were included in this study. Grip-strength measurements were taken by the shoulder 0ºneural flexion and 90ºflexion with respect to elbow positioned at 0 degree extension and 90 degrees of flexion. Grip strength was used as an outcome measure for the study. Results: The highest mean grip strength was recorded; when the shoulder was positioned in neutral flexion with elbow in 0 degree extension with respect to the wrist in neutral (42.90±11.87). The lowest mean grip strength was recorded; when the shoulder was positioned in 90 degree flexion with elbow in 90 degree flexion with respect to wrist in neutral (28.83±13.52). Comparison between the gender shows a significant difference between the male and female in which male has greater grip strength than the female in all positions. The highest mean grip in males and females were documented when the shoulder was positioned in neutral flexion with elbow in 0º extension with respect to the wrist positioned in neutral. The results of ANOVA findings indicated significant differences (p<0.05) in grip strength between shoulder 90º flexion with respect to elbow 90º flexion and 0º extension. Pearson Product-Moment Correlation Coefficient of age and different positions of shoulder with respect to the elbow positions and results showed that there is No linear relationship between age and different positions of the shoulder and elbow (r=0). Conclusion: This study confirms that various joint positions can affect grip strength, especially the elbow and shoulder joints with respect to wrist positions neutral. It would be reasonable to evaluate the hand injured patient"s grip strength using different combined shoulder and elbow positions to determine their maximal grip force. Clinically useful information may be derived from these findings and are valuable in the evaluation and rehabilitation training of hand injured patients.
Factors Affecting Hand Grip Strength and Its Evaluation: A Systemic Review
International Journal of Physiotherapy and Research, 2015
Hand is a vital and inevitable organ for humans. It functions start from a fine to gross motor activities. Many daily functions and sports events require high activity of hands. Hand and forearm muscles are important in grip strength. The American society of hand therapist (ASHT) recommended testing protocol in which the subject is seated upright against the back of a chair with flat on the floor. A literature survey covering the fields of ergonomics, medicine, biology and anthropology was conducted to develop a database. We suggest that a standard method is needed to enable more consistent measurement of grip strength and better assessment.
Influence of Different Testing Postures on Hand Grip Strength
European Scientific Journal, 2014
Hand grip strength (HGS) is a useful, functional measure of the integrity of upper extremity, however many studies examined it from selected positions (supine, sitting, standing), with no emphasis on other derived positions that are used in a clinical setting. The objective was to evaluate HGS in different body positions that are used in a clinical setting by using a standard protocol. A convenience sample of 40 healthy male participants was recruited for this study, with no history of psychiatric or neurological dysfunction, or upper extremity orthopedic dysfunction. Grip strength was measured in the dominant hand with Jamar Plus+ digital hand dynamometer in five positions: supine, prone, side-lying, sitting and standing. The HGS value in the prone position was significantly lower than that in standing position (p = 0.043) and the sitting position (p = 0.013). However, no statistical difference was found in HGS among supine, prone, side-lying positions. Grip strength correlated moderately with age (r = 0.643). This study provides a useful evaluation of grip strength in different positions. Using identical upper extremity positions, grip strength is variable among different body positions. Grip strength is equivalent when tested from the supine, side-lying or prone, thus position can be adjusted according to the patient's condition. Finally, Age is one of the important determinants of the hand grip evaluation, particularly when standing position is used.

Introduction: Health-related physical fitness requires muscular strength to perform physical activities. The handgrip test is used to assess the muscular strength of the hand. The flexor muscle strength in palmar, thenar, and hypothenar areas of the hand collectively form the Handgrip Strength (HGS). However, the extensor mechanism, including the intrinsic musculature, plays a minor role in producing handgrip strength. Also, each finger plays an essential role in handgrip strength. This study aims to identify the association between the handgrip strength and the handspan of the dominant and non-dominant hands of undergraduate physical therapy students. Materials and Methods: A cross-sectional observational study was conducted on undergraduate physical therapy students. Different public and private physical therapy schools and universities in Karachi City, Pakistan were chosen to collect the data with an estimated sample size of 100 undergraduate physical therapy students. The sampling was done by the non-probability convenient sampling method. The inclusion criteria were undergraduate physiotherapy students (from both genders) and willing to participate in the study. Results: The Pearson test was used to determine the significant correlation between handgrip strength and handspan. The results showed the mean and standard deviation of handgrip strength (dominant hand) was 25.96±11.538, of handgrip strength in Kg (non-dominant hand) was 24.93±12.336, and of handspan length in Cm of the dominant hand was 20.2910±1.78671. The present study showed a positive association between handgrip strength and handspan. The handgrip strength of the non-dominant hand was higher than the dominant handgrip strength values. Handspan was also higher in the non-dominant hand compared with the dominant hand, but this difference is not significant. Conclusion: The handgrip strength of physical therapy students had a positive association with the handspan. The handspan and dominant hand influence handgrip strength.
Effects of Hand Position with Relation to Elbow and Shoulder Position on Maximum Grip Strength
Journal of Exercise Science and Physiotherapy, 2016
This study aimed at determining the grip strength at various angles of shoulder and elbow positions and associate them with discomfort at each point. Method: 60 right handed male subjects aged 20-35 years were taken to measure grip strength at shoulder forward flexion at 0º,45º,90º,135º,180º with elbow at 0º and 90º flexion; discomfort was measured with a VAS scale. Result: scores of grip strength: minimum at 90º elbow and 180º shoulder and maximum at 0º elbow and 180º shoulder. VAS score: the maximum at 0 º elbow and 135 º shoulder and minimum at 0º elbow and 0º shoulder. Conclusion: there exists a relation between grip strength and discomfort.
Grip Strength Changes in Relation to Different Body Postures, Elbow and Forearm Positions
2013
Background of the study: Several activities in day to day life involving upper limb require good hand grip strength. A reliable evaluation of hand grip forms an integral part of rehabilitation, not only to assess the strength of muscles involved in gripping but also to apply as a tool in rehabilitating patients with variable levels of hand injuries. Various sports require some degree of grip strength which improves performance and plays a key role in preventing overall injuries relevant to forearm and hand. Since hand grip is considered to be affected by positions of various segments of the body, this study was designed to evaluate grip strength at three different body postures, three different forearm positions and two elbow positions, results of which would establish an optimal body posture and position of segments to evaluate and train for maximal grip strength. Materials and Methods: 40 healthy students from department of Physiotherapy and School of Nursing (20 male and 20 femal...
Effect Of Elbow And Wrist Joint Position On Grip Strength
Background and Objective: Grip and pinch strength measurements provide an objective index of the functional integrity of the upper extremity. Hand strength evaluation is importance in determining the effectiveness of different treatment strategies or effects of different procedures. As studies on the effect of elbow and wrist positions on grip strength remain controversial, the present study aimed to find out the effect of elbow and wrist joint positions on grip strength and the favorable and advantageous position to improve grasp function. Method: This study included 144 healthy normal subjects with 13 males and 131 females. A standard adjustable hydraulic hand dynamometer was used for measuring grip strength of various positions of elbow and wrist. Result: The result of the study showed that the elbow and wrist positions had impact on the grip strength when considered individually (p<.01). But the interaction effect of these two different positions could not able to show any significant difference. Conclusion: Grip strength was maximum with elbow in full extension and wrist in neutral. The changes in wrist position on grip strength were observed with variations in elbow and wrist positions.
Serial Grip Strength Testing- Its Role In Assessment Of Wrist And Hand Disability
The Internet Journal of Surgery, 2004
Handgrip strength testing has long been used as a tool in the clinical assessment of hand and wrist injury. Of particular interest have been attempts to utilise strength testing to detect sincerity of maximum voluntary effort. This has particular relevance to monetary payment in worker's compensation, motor vehicle accident and medical insurance claims. This paper recommends using the Jamar dynamometer as a measurement tool because it is the most widely researched and reported grip strength measurement device available. It also looks at the different tests developed to determine an individual's level of effort during grip strength testing. A protocol is suggested for a time and cost efficient grip strength assessment that should be used in conjunction with clinical acumen when assessing hand and wrist disability.
