Styf J, Hutchinson K, Carlsson S, Hargens A
Psychosom Med . 2001 Nov; 63(6):862-4. PMID: 11719622
Objective: The objective of this study was to develop a ground-based model for spinal adaptation to microgravity and to study the effects of spinal adaptation on depression, mood state, and...

Styf J, Carlsson S
J Spinal Disord . 1999 Nov; 12(5):375-9. PMID: 10549699
The authors studied the predictive value of a psychometric evaluation of 50 patients (14 women, 36 men) with a mean age of 40 years who were treated by extirpation of...

Haruna Y, Styf J, Kahan N, Hargens A
Aviat Space Environ Med . 1999 Apr; 70(3 Pt 1):220-4. PMID: 10102732
Background: Increased spinal height due to the lack of of axial compression on spinal structures in microgravity may stretch the spinal cord, cauda equina, nerve roots, and paraspinal tissues. Hypothesis:...

Lundin O, Styf J
Am J Sports Med . 1998 Aug; 26(4):567-70. PMID: 9689380
The effects of a functional knee brace on intramuscular pressure in the leg and thigh were measured in eight subjects with a mean age of 32 years. Pressures in the...

Wiger P, Styf J
J Orthop Trauma . 1998 Jul; 12(5):343-7. PMID: 9671186
Objectives: To study the effects of limb elevation on abnormally increased intramuscular pressure (IMP) and blood perfusion pressure in the anterior compartment of the leg. Design: An experimental cross-over design....

Styf J, Willen J
Spine (Phila Pa 1976) . 1998 Mar; 23(3):354-8. PMID: 9507625
Study Design: An experimental study on patients undergoing posterior lumbar spine surgery. Objectives: To study the relation between external compression and muscle strain induced by spinal retractors and intramuscular pressure...

Mohler L, Styf J, Pedowitz R, Hargens A, Gershuni D
J Bone Joint Surg Am . 1997 Jun; 79(6):844-9. PMID: 9199381
Currently, the definitive diagnosis of chronic compartment syndrome is based on invasive measurements of intracompartmental pressure. We measured the intramuscular pressure and the relative oxygenation in the anterior compartment of...

Styf J, Ballard R, Fechner K, Watenpaugh D, Kahan N, Hargens A
Aviat Space Environ Med . 1997 Jan; 68(1):24-9. PMID: 9006878
Background: Spinal lengthening and back pain are commonly experienced by astronauts exposed to microgravity. Methods: To develop a ground-based simulation for spinal adaptation to microgravity, we investigated height increase, neuromuscular...

Chang D, Breit G, Styf J, Hargens A
Am J Physiol . 1996 Oct; 271(4 Pt 2):R961-6. PMID: 8897988
Our objective was to understand how weight bearing with varying gravitational fields affects blood perfusion in the sole of the foot. Human subjects underwent whole body tilting at four angles:...

Styf J, Lundin O, Gershuni D
Am J Sports Med . 1994 Nov; 22(6):830-4. PMID: 7856808
The effects of a functional knee brace on local intramuscular pressures and on calculated blood perfusion pressure in the tibialis anterior muscle of the legs of six volunteers were determined....
