“…This pattern consists of the range of motion (ROM) of the single joints and their coordination. Our results regarding ROM of the finger joints and modulation when gripping objects of different sizes have already been presented (Gülke et al, 2010). While in clinical practice one continues to focus on ROM, this study analyzed the interdependence of this movement.…”

The purpose of this study was to assess whether there is a universal pattern of movement of the finger joints while performing a cylinder grip. A sensor glove was used to record the finger joint motion of 48 participants. Our observations showed that when examining the fingers, flexion motion began either at the metacarpophalangeal (MP) or proximal interphalangeal (PIP) joints, with the distal interphalangeal (DIP) joints always last to move (p = 0.0052). The sequence of the joints at the end of the gripping motion was different than at the beginning. Here, the only statistically significant observation was that the DIP joints fully flexed only once the MP joints had flexed fully. Apart from that, it was completely variable which joint reached its final position first or last. The analysis also revealed that synchronization of four identical joints (i.e. the four PIP joints) was significantly higher than synchronization of the 12 finger joints. Although synchronization was already high at the beginning of the flexion motion, it increased significantly by the time the joints completed their movement.

“…A previous study described that the functional flexion ROM of the finger MCP joints was 61 by measuring the joint position of participants' finger as they grasped objects (Hume, Gellman, McKellop, & Brumfield, 1990); by contrast, Hayashi and Shimizu (2013) reported that the maximum flexion angle of the finger MCP joints used in daily activities was much greater than 61 . Gülke et al (2010) reported that the finger MCP joints flex from about 50e60 even while holding a 4-cm-diameter cylinder. The finger MCP joints require greater flexion to pick up small objects.…”

Objective/Background: This study was conducted to ascertain the necessary flexion or extension range of motion (ROM) required for the finger metacarpophalangeal (MCP) joints to maintain hand function. Methods: Twenty-one healthy adults were recruited for participation in this study. Each participant's right-hand function was evaluated using the JebseneTaylor hand function test and the O'Connor finger dexterity test. Experiment 1 was conducted to assess the influence of the orthosis on hand function. The function of each participant's right hand was measured without an orthosis, with all the finger MCP joints limited to 90 of flexion and 45 of hyperextension. Experiment 2 was conducted to evaluate the impact of limited flexion and extension of all the MCP joints on hand function. The movements of all the finger MCP joints were limited to 70 , 60 , 50 , and 40 of flexion and 20 , 30 , 40 , and 50 of extension lag using orthoses. Results: No significant difference was found between a normal hand and a hand with either flexion of 90 or hyperextension of 45 in Experiment 1. In Experiment 2, no significant difference was found between a normal hand and a hand for which the flexion angle was 70 , with an extension lag of 30 or 20. Conclusion: The necessary ROMs of the MCP joints to maintain hand function are flexion ROM >70 with an extension ROM <30 of extension lag.

“…Attempts at quantifying this process in a way that may be usable for robot control are few. Glke et al [36], Bae and Armstrong [37] showed that the finger motion during reach to grasp tasks could be described by a simple polynomial function of time, while Ulloa and Bullock [38] modeled the covariation of the arm and the finger motion. Interestingly, these authors also report on an involuntary reopening of the fingers upon perturbation of the target location; an observation which we will revisit in this paper.…”
