Hung C, Allen F, Pollack S, Brighton C
J Biomech
. 1996 Nov;
29(11):1411-7.
PMID: 8894921
In this study, we sought to determine if there is a requirement for calcium entry from the extracellular space as well as calcium from intracellular stores to produce real-time intracellular...

J Biomech
. 1996 Nov;
29(11):1403-9.
PMID: 8894920
Cultured cells subjected to fluid flow are exposed to mechanical forces and electrokinetic forces. The convective current establishes an electrokinetic force created by the flow-dependent transport of mobile ions in...

Clin Orthop Relat Res
. 1996 Jul;
(328):241-9.
PMID: 8653964
Recent clinical trials in osteoporotic patients show that cyclical etidronate therapy can increase vertebral bone mass and reduce the incidence of vertebral fractures. Stress generated potentials, which are theorized to...

Clin Orthop Relat Res
. 1995 Dec;
(321):223-34.
PMID: 7497673
Two hundred seventy-one tibial nonunions of average duration of 23.5 months (range, 9-69 months) were treated with direct current (167 patients), capacitive coupled electrical stimulation (56 patients), or bone graft...

Clin Orthop Relat Res
. 1995 Apr;
(313):256-69.
PMID: 7641488
Using a parallel-plate flow chamber and fura-2 fluorescence microscopy, intracellular calcium was measured cell by cell in preconfluent primary culture rat calvarial bone cells to 18, 35, and 70 dynes/cm2...

J Biomed Mater Res
. 1995 Jan;
29(1):47-57.
PMID: 7713958
The morphology of bone may be influenced by many factors, including electromechanical ones such as electric potentials, electric fields, or zeta potentials. Stress-generated potential studies in bone and particle electrophoresis...

J Bone Joint Surg Am
. 1994 Apr;
76(4):489-501.
PMID: 8150816
The purpose of this study was to determine whether low-power-consuming symmetrical-waveform electromagnetic stimuli could increase the stiffness of fracture sites in a rabbit fibular-osteotomy model. Both active and placebo devices...

Kowalchuk R, Pollack S
J Orthop Res
. 1993 Nov;
11(6):874-83.
PMID: 8283333
It is now generally accepted that stress-generated potentials (SGPs) at low frequencies are due to an electrokinetic phenomenon in the small interior surfaces of bone and are directly proportional to...

J Biomed Mater Res
. 1993 Jun;
27(6):783-90.
PMID: 8408108
Concurrent work demonstrates that the zeta potential of bone is multivalued and systematically alterable by changes in sample preparation, steeping fluid composition, and steeping time. Since bone mineral is a...
