“…P < 0.05 was considered statistically significant. We estimated that a sample size of 16 participants per group would be required to achieve 80% power to detect a 10° difference in the aggregated angle for the two groups, assuming an overall standard deviation of 10°, similar to what was observed in a previous study [ 35 ].…”

A new method of measuring the thumb pronation and palmar abduction angles during opposition movement using a three-axis gyroscope

BackgroundThumb opposition is vital for hand function and involves pronation and palmar abduction. The improvement of pronation is often used as one of the evaluation items of the opponensplasty method for severe carpal tunnel syndrome. However, most of the studies used substitution evaluation methods for measurement of the pronation angle. Thus, there is still no appropriate method for measuring thumb pronation angle accurately in carpal tunnel syndrome patients.In recent reports, a wearable gyroscope was used to evaluate upper extremity motions and it can be possibly used for accurate measurement of the thumb pronation angle along the three-dimensionally moving bone axis.Thus, we investigated the reliability of measuring thumb pronation using a gyroscope and evaluated whether this method can be used to detect opposition impairment.MethodsThe participants were volunteers with unaffected upper limbs (32 hands) and patients with carpal tunnel syndrome (27 hands). The pronation and palmar abduction angles during opposition movements were measured using a three-axis gyroscope that included a three-axis accelerometer. The gyroscope was fixed onto the first metacarpal bone and the thumb phalanx.ResultsThe pronation and palmar abduction angles of the metacarpal bone and the palmar abduction angles of the phalanx significantly decreased in the carpal tunnel syndrome group. The pronation angle of the metacarpal bone during opposition movement peaked later than the palmar abduction angle in all hands.ConclusionsWe were able to measure the thumb pronation and palmar abduction angles using the three-axis gyroscope, and this tool was able to detect impairments of thumb opposition due to carpal tunnel syndrome. This could be a tool for measuring thumb and finger angles and for detecting impairments caused by various diseases.

“…Their publications provide new insight into the neuromuscular control of the thumb and the importance of a maintained sensorimotor innervation. In earlier reports, they found that carpal tunnel syndrome, the most common nerve entrapment treated by hand surgeons, reduces thumb motion and flexion/extension ability in the thumb joints [3]. In addition, they observe that carpal tunnel syndrome alters proprioceptive performance in reach and grasp functions [4], and adversely affects the fine motor skills required in precision pinch tasks [5].…”

“…It is caused by compression of the median nerve at the wrist. Particularly in patients with severe CTS, it is known that the palmar abduction of the carpometacarpal (CM) joint is restricted (e.g., [19]). Since the opposition of the thumb is hindered, significant change in grasping posture of the hands is expected when their palmar abduction of the CM joint is limited.…”

For virtual evaluation of universal design products, it is necessary to synthesize natural grasps for various hands including those with limited range of motion (ROM). In this paper, we study synthesizing grasps for digital hands with limited ROM in their thumbs' joints. We apply a contactregion-based method for grasp synthesis to this problem. In our previous study, two types of grasps were observed under the limitation of the thumb's ROM. One was a type that used the lateral region of the thumb, and the other was a type that used the same contact regions as healthy hands. In this paper, grasps are synthesized for two objects using three hand models whose lengths are different. With the same input information as the healthy hand, it is not possible to synthesize the grasps for the ROM-limited hand. On the other hand, when grasps are synthesized by changing the information about grasping target points of the thumb and the palm, feasible grasps for the ROMlimited hand can be found. For a camera object, the grasp using the thumb's radial region is automatically synthesized without changing the specified contact region. Also, for a spray object, a grasp that uses the same contact region as the healthy hand is synthesized. These results demonstrate our method can synthesize natural grasps even for ROM-limited hands, which will contribute to universal product design.

Carpal Tunnel Syndrome Impairs Thumb Opposition and Circumduction Motion

Abstract: Improving understanding of thumb pathokinematics associated with carpal tunnel syndrome may help clarify hand function impairment associated with the syndrome given the critical role of the thumb in dexterous manipulation.
