Relationships within and between lower and upper extremity dysfunction in people with diabetes.

Introduction: Diabetes mellitus (DM) is associated with systemic musculoskeletal system impairments suggesting concurrent development of lower and upper extremity musculoskeletal problems. This study aims to examine relationships between lower and upper extremity function in people with DM.

Methods: Sixty people with type 2 DM and peripheral neuropathy [mean (standard deviation); 67(6) years old, DM duration 14(10) yrs] completed the following measures: 1) Self-reports of function: Foot and Ankle Ability Measure (FAAM; higher = better function) and Shoulder Pain and Disability Index (SPADI; lower = better function), 2) Range of motion (goniometry): ankle dorsiflexion and shoulder flexion, and 3) Strength: unilateral heel rise power (UHR, 3D kinetics) and hand grip dynamometry.

Examination of the Lumbar Movement Pattern during a Clinical Test and a Functional Activity Test in People with and without Low Back Pain.

Background: It is assumed that the lumbar movement pattern observed during a clinical test is representative of the movement pattern used during a functional activity. Very little is known about how the lumbar movement pattern during a clinical test is associated with the lumbar movement pattern during a functional activity and how the lumbar movement pattern is associated with functional limitation.

Objective: The purpose was to examine the lumbar movement pattern during a clinical test and a functional activity test in people with and people without low back pain (LBP), and the relationship of lumbar motion to LBP-related functional limitation.

Intravenous contrast-free standardized exercise perfusion imaging in diabetic feet with ulcers.

Background: Impaired foot perfusion is a primary contributor to foot ulcer formation. There is no existing device nor method that can be used to measure local foot perfusion during standardized foot muscle exercise in an MRI environment.

Purpose: To develop a new MRI-compatible foot dynamometer and MRI methods to characterize local perfusion in diabetic feet with ulcers.

Diffusion Tensor Imaging of the Calf Muscles in Subjects With and Without Diabetes Mellitus.

Background: Diffusion tensor imaging (DTI) has been used to characterize calf skeletal muscle architecture.

Purpose: To assess the diffusional properties of the calf muscles of subjects with and without diabetes, at rest and during isometric plantarflexion exercise.

Study Type: Prospective.

Effect of a Shoulder Movement Intervention on Joint Mobility, Pain, and Disability in People With Diabetes: A Randomized Controlled Trial.

Background: People with diabetes are at high risk for shoulder pain, limited joint mobility, and adhesive capsulitis.

Objective: The objective of this study was to evaluate the effects of a shoulder movement intervention (ShoMo) compared to a wellness intervention on the primary outcomes of active shoulder flexion and reported Shoulder Pain and Disability Index (SPADI) measured after intervention and 9 months later.

Design: The design was a prospective, randomized, controlled clinical trial.

Relationship of shoulder activity and skin intrinsic fluorescence with low level shoulder pain and disability in people with type 2 diabetes.

Aim: People with type 2 diabetes (T2DM) have a high incidence of musculoskeletal disorders thought to be influenced by high non-enzymatic advanced glycated end-products (AGEs). The goals of this study were to determine differences in shoulder activity level and AGEs in people with T2DM compared to matched controls, and to determine factors associated with shoulder pain and disability.

Methods: Eighty-one participants, T2DM (n=52) and controls (n=29), were examined for magnitude and duration of shoulder activity (measured using accelerometers), skin intrinsic florescence (SIF) as a surrogate measure of AGE level, and the Shoulder Pain and Disability Index (SPADI) as a self-report of shoulder pain and disability.

Asymmetry of lumbopelvic movement patterns during active hip abduction is a risk factor for low back pain development during standing.

An induced-pain paradigm has been used in back-healthy people to understand risk factors for developing low back pain (LBP) during prolonged standing. We examined asymmetry of lumbopelvic movement timing during a clinical test of active hip abduction in back-healthy people who developed LBP symptoms during standing (Pain Developers; PDs) compared to back-healthy people who did not develop LBP symptoms during standing (Non Pain Developers, NPDs). Participants completed the hip abduction test while movement was recorded with a motion capture system.

Psychological Factors Are Related to Pain Intensity in Back-Healthy People Who Develop Clinically Relevant Pain During Prolonged Standing: A Preliminary Study.

Background: An induced-pain paradigm has been used to examine risk factors for the development of low back pain (LBP) during prolonged standing in back-healthy people (standing paradigm). Previous studies that used induced-pain methods suggest that pain intensity may be related to psychologic factors. It is not currently known, however, whether pain intensity reported during the standing paradigm is related to psychologic factors.

Association between rotation-related impairments and activity type in people with and without low back pain.

Objective: To determine whether people with low back pain (LBP) who regularly participated in a rotation-related activity displayed more rotation-related impairments than people without LBP who did and did not participate in the activity.

Design: Secondary analysis of data from a case-control study.

Setting: Musculoskeletal analysis laboratory at an academic medical center.

Is lumbar lordosis related to low back pain development during prolonged standing?

Background: An induced-pain paradigm has been used in back-healthy people to understand risk factors for developing low back pain during prolonged standing.

Objectives: The purposes of this study were to (1) compare baseline lumbar lordosis in back-healthy participants who do (Pain Developers) and do not (Non-Pain Developers) develop low back pain during 2 h of standing, and (2) examine the relationship between lumbar lordosis and low back pain intensity.

Design: Cross-sectional.

Validity of a Paradigm for Low Back Pain Symptom Development During Prolonged Standing.

Objectives: Examine the validity of an induced pain paradigm in which people stand while performing simulated light work tasks (standing paradigm).

Materials And Methods: Initially, people with low back pain (LBP) reported the quality and location of their typical symptoms on a body pain diagram. Then, people with LBP and back-healthy people stood for 2 hours and reported the intensity, quality, and location of symptoms at baseline and every 15 minutes.

The effects of postseason break on knee biomechanics and lower extremity EMG in a stop-jump task: implications for ACL injury.

The effects of training on biomechanical risk factors for anterior cruciate ligament (ACL) injuries have been investigated, but the effects of detraining have received little attention. The purpose of this study was to evaluate the effects of a one-month postseason break on knee biomechanics and lower extremity electromyography (EMG) during a stop-jump task. A postseason break is the phase between two seasons when no regular training routines are performed.

The effects of postseason break on stabilometric performance in female volleyball players.

Ankle sprain is a common injury in volleyball. Poor stabilometric performance (SP) is associated with high risks of sustaining ankle sprain. Balance training can improve SP and reduce ankle sprain, but no research has studied the effects of detraining on SP in highly trained athletes.
