In the study of range of movement of wrist joint, accurate measurements on normal subjects are important since these have a bearing on diagnosis and prognosis in disease state. Objective: To determine the effects of age and gender on wrist motion in normal subjects on both hands. Material and Method: Four hundred subjects (Two hundred male and Two hundred Female) with the four age groups with no history of injury to the wrist joint were subjected to goniometric measurements with the wrist in ulnar and radial deviation of both hands through universal goniometer in Central Gujarat population. Result: Readings were noted, the radial deviation and total range of motion were higher in left hand as compared to right (p=<0.005). In addition, Female subjects showed higher range of motion than male and joint range of movement decrease with the increase of the age(r= -0.147 in right hand and r= -0.243 in left hand). Conclusion: The range of motion was reduced with the increases of age because of the presence of osteoporosis, cumulative damage and obesity with ageing process. Generally, females tend to have greater range of motions, due to the anatomical and physiological differences, such as the size of muscle mass, joint geometry and hormone. The reduced mobility on the right side compare with that on the left might have been the result of slight degenerative changes in the joint as well as damage to the ligaments of the right upper extremity in the right handed population.

Background: The measurement of joint movement is an important component of a comprehensive physical examination of the all extremities by which one enables health professionals to accurately assess dysfunction and rehabilitative progress. Aim: To determine the normal range of motion or angle of the joint at Wrist via the performance of active joint motion of the subjects during the evaluation allows the examiner to screen for abnormal movements and gain information about the subject’s willingness to move. Resisted isometric muscle contraction and tests are used in conjunction with Goniometry to help isolate the injured anatomical structure. Materials and Methods: All the subjects (400 Subjects) studied had a normal wrist joint skeleton which was included in the present study. All subjects were divided into four age groups and wrist joint were subjected to goniometric measurements with the movement ulnar and radial deviation and flexion and extension of both hands through universal G...
Variation of Range of Joint Motion in Bengalee (Indian) Healthy Adult Subjects
Journal of Life Sciences, 2012
The present investigation was made to find out the effect of age and sex on Range of Motion (ROM) and gradation of ROM among healthy adults. A total number of 353 subjects (180 male and 173 female) having the age range of 19-60 years were selected at random from Bengali population of different districts of West Bengal for the study. The subjects were further classified into age and sex groups. A digital goniometer was used for the study. The results showed that there was no significant difference of ROM between right and left side of the body of both sexes' subjects. There was a significant difference of ROM among different age groups (p<0.05, p<0.001). In most of the body joint angles, a gradual decrease of ROM was observed with advancement of the age. According to the computed norms for each ROM, most of the subjects belonged to "C" grade (that is,'average') for both sexes. It can be concluded that gender wise difference in ROM may be attributed to the difference in activity level. Age related decrement of ROM may be related to the reduced flexibility of the body in older age and may be a helpful guide for designing different workstations.

BACKGROUND: Data on the physical strength capabilities of users are essential for designing the safe and usable products. OBJECTIVE: The aims of this study were to characterise the wrist ulnar/radial (U/R) torque strength and individual strength differences among Iranian population. METHODS: The study was conducted among 769 (391 males, 378 females) participants aged 5-74 years in the northwest of Iran. Measurements were carried out with both dominant and non-dominant hands using a digital angle torque adaptor installed in a jar-shaped measuring unit. RESULTS: The results indicated that the mean wrist U/R torque strength exertion by females was 75% of that exerted by males. Strength exertion with the non-dominant hand was 8% lower than strength exertion of the dominant hand. A significant positive association was also found between the wrist U/R torque strength and body mass index. CONCLUSIONS: This additional information on the wrist torque strength can fill the gap in the strength data for Iranian population, or used by health and safety practitioners in the field.

Excessive or insufficient levels of passive musculoarticular stiffness (PMAS) can lead to joint impairment or instability. Quantifying the PMAS may provide a better understanding of neurological or musculoskeletal disorders. The aims of the present study were multiple: first, to assess the reliability of quantifying PMAS and to collect normative data on the wrist in healthy participants, and second, to assess the effect of age and body size on PMAS. For this purpose, a total of 458 participants from 3 to 90 years old were analyzed with an electromechanical oscillation device (EOD). Passive sinusoidal movements were induced in a flexion/extension pattern in the participants' wrists, enabling an objective measurement of elastic stiffness (EL) and viscous stiffness (VI). Both the dominant and non-dominant wrists were assessed. Two-way repeated-measures ANOVA revealed a sex differentiation from puberty (12–18 years old) and an increase of EL and VI from childhood to adulthood and a ...

Introduction: For the past few years wrist pain has been related to repetitive movement of the hand, and the cases has been increasing dramatically. There are numerous factors that causes wrist pain especially occupational factors. Different population has been investigated regarding work-related wrist pain such as, factory workers, programmers, and even gamers. Up to now, there is no data baseline about the prevalence and risk factors of wrist pain among young adults. Objectives: To investigate the prevalence and risk factors of risk pain among young adults in University Tunku Abdul Rahman (UTAR) during Movement Control Disorder. Methods: Questionnaire was adapted from Patient Rated Wrist Evaluation Score (PRWE), Self-Developed Demographic Data was used to determine prevalence and potential risk factors for wrist pain on young adults in UTAR during Movement Control Disorder, by using convenient sampling method. Results: A total number of 144 participants had completed the questionnaire. Most of the participants were 20-25 years old. There are 100 female participants (69.4%) and 44 male participants (29.9%) who enrolled in this research. The prevalence of wrist pain among young adults in UTAR during Movement Control Disorder is relatively high according to PRWE score (71.53%) while according to self-modified questionnaire there are 33 participants who felt the pain at the wrist (22.92%). Conclusion: Repetitive movement of the wrist and poor ergonomics of the hand are the factors that cause of wrist pain among young adults in UTAR.
Normal Range of Motion of Lower Extremity Joints in Mongolian Subjects
Engineering Proceedings, 2021
It is important to identify the normal range of motion (ROM) of the human joints for both biomechanical and clinical applications. For health care providers, including physicians and therapists, the restoration of normal ROM is a difficult task. The severity of impaired joint mobility or the postoperative rehabilitation process must be evaluated in comparison with a normal reference value. However, there are no studies that have reported the ROM of Mongolian subjects. In this study, we measured the hip, knee, and ankle joint angles using multiple wearable inertial sensors. Ten healthy young subjects participated. The three-dimensional (3D) motion data were collected while the subject were walking at normal speed. In our knowledge, this study is the first to analyze the normal ROM of Mongolian male subjects. The collected data can be used as reference values for evaluating the disability of the motion and performance in rehabilitation programs.
