In EF4T and EMT, (9,15) ECRL
and ECRB is used as the donor tendon, respectively with TFL as a tendon graft to restore the active flexion of the MCP joints and extension of the interphalangeal joints of the digits.
If the WDFHO is fitted on a hand controlled by a weak wrist extensor musculature, the mechanical joints of the WDFHO are prone to coincide with the anatomical joints during the wrist ROM because the ECRB and ECRL muscles are not strong enough to concur with radial deviation.
The limitation reported in the single-channel FES system gives us insight that more efficient tenodesis grasp can be achieved by combining the WDFHO with an FES system that stimulates ECU to counteract the undesirable radial deviation caused by stronger ECRB and ECRL in persons with C6 and C7 tetraplegia.
2] = carbon dioxide, ECRB = extensor carpi radialis brevis, ECRL = extensor carpi radialis longus, ECU = extensor carpi ulnaris, EMG = electromyography, FES = functional electrical stimulation, FHO = flexor hinge orthosis, IP = interphalangeal, MCP = metacarpophalangeal, MMT = manual muscle test, MVC = maximum voluntary contraction, ROM = range of motion, SCI = spinal cord injury, WDFHO = wrist-driven flexor hinge orthosis.
4) Electromyography (EMG), which has been identified as the best technique with respect to localizing the lesion, (6) confirmed normal motor unit potentials (MUP) with full recruitment from the left triceps, brachioradialis, ECRL
, and ECRB as well as reduced recruitment with a variable degree of positive sharp waves and fibrillation potentials from the extensor digitorum communis (EDC), ECU, EI, APL, extensor pollicis longus (EPL), and extensor pollicis brevis (EPB) muscles.
FGV through its logistics and others (LO) arm had recently invited a team from ECRL to visit its Felda Transport Services Kuantan Depot Open Yard Facility and Felda Johore-Bulkers Kuantan Warehouse in Kuantan Port
He noted that an estimated 10% of the 7-year construction period of the ECRL project would involve logistics support.
FGV officer-in-charge Datuk Khairil Anuar Aziz said as ECRLs building work would be based in Kuantan before it expands to Kelantan and Selangor, FGV had the advantage of providing logistics services for the project as its facilities are either in or near Kuantan Port.
For the stiff hand, with mild contractures present, we recommend an ECRL or FDS to lateral band insertion.
In the first stage, the PT is transferred to ECRB and yoked to the ECRL, and re-routed to the base of the ring metacarpal.
Malaysias transport minister Datuk Seri Liow Tiong Lai said that China will manage detailed engineering and design of the ECRL
, acquire all materials and equipment, and hand over the facility to Malaysia.
