The articular system in the digit is connected by mechanical link and lumbrical muscle is one of the links in this system that produces dynamic controlled extension of interphangeal joints.
PATTERN OF ORIGIN OF LUMBRICAL MUSCLES(STUDY OF 40 HANDS) Normal type Lumbrical Muscle No.
has reported anomalous lumbrical muscle originating from the forearm and inserted in the region of the index finger compressing the median nerve.
In the present study, first lumbrical muscle is inserted into dorsal digital expansion in 35 specimens.
Chaundrue et al have found compression of radial and ulnar collateral arterial system by hypertrophy of lumbrical muscle producing white finger.
The aim of this study was to ascertain if KMI can facilitate activation of the hand lumbrical muscles in the post-stroke hemiparetic hand.
The results of this study suggest that KMI, alongside physical treatment, is an effective means to facilitate activation of the lumbrical muscles in the hemiparetic hand.
Facilitation of activation in lumbrical muscles, repeated 10 times.
