Wearable Sensor Array Design for Spine Posture Monitoring During Exercise Incorporating Biofeedback

Physical therapy (PT) exercise is an evidence-based intervention for non-specific chronic low back pain, spinal deformities and poor posture. Home based PT programs are aimed at strengthening core muscle groups, improving mobility and flexibility, and promoting proper posture. However, assessing unsupervised home-based PT outcomes is a generally difficult problem due to lack of reliable methods to monitor execution correctness and compliance. We propose a monitoring method consisting of a wearable sensor array to monitor three geodesic distances between two points on the surface of the shoulders and one point on the lower back. The sensor array may be built into a custom garment or a light weight harness wirelessly linked to a pattern recognition algorithm implemented in a mobile app. We use a new type of triangular stretch sensor array design which can generate a unique signature for a correct spine therapy exercise when performed by a specific subject. We conducted a pilot test consisting of three experiments: (i) two exercise patterns simulated by a mechanical device, (ii) one PT case of a scoliosis therapy exercise including spinal flexion, extension, and rotation performed by one volunteer patient, and (iii) a set of three lower back flexibility exercises performed by six subjects. Overall, the results of correctness recognition show 70–100% sensitivity and 100% specificity. The pilot test provides key data for further development including clinical trials. Th...

We report a case of double-level lumbar spondylolysis at L4 and L5 that was successfully treated with the double "smiley face" rod method. A healthy 29-year-old man who presented with a 6-year history of chronic low back pain was referred to us for surgical treatment. Plain radiographs and computed tomography of the lumbar spine revealed bilateral pars defects at L4 and L5 without slip or scoliosis. The patient underwent direct repair of the pars defects using the double smiley face rod method at L4 and L5. There were no intraoperative or postoperative complications, and the patient had improved clinically by 1 y...

Several interactive pelvic axes occur during activities of weight-bearing and ambulation. Flexion and extension of the symmetrical innominates occur on the sacral x-axis with weight-bearing. Normal asymmetric innominate rotation occurs on the innominate axis at the pubic symphysis during weight-bearing with normal ambulation. Oblique sacral movement occurs on an oblique sacral axis concurrent with asymmetric innominate movement. Acute and chronic low back pain is commonly caused by a bilateral symmetrical or oblique anterior innominate rotation on the sacrum on an acetabular axis, usually while lifting, bending, lowering, ...

ConclusionLBP and lumbar degeneration are common in PD. Both are related to movement disorder symptoms. The knowledge about musculoskeletal conditions in Parkinson ’s disease is important for an interdisciplinary conservative or operative treatment decision of LBP.Graphical abstractThese slides can be retrieved under Electronic Supplementary Material.

BACKGROUND CONTEXT: Patients with adult degenerative scoliosis (ADS) demonstrate an altered gait pattern. Age related changes such as progressive and asymmetric degeneration of the disc and facet joints are associated with degenerative adult scoliosis and lead to segmental instability, deformity and stenosis. Psychological clinical outcome questionnaires (FABQ and TSK) are a reliable and valid measure of the fear of movement related to chronic lower back pain. Self-report measures are routinely used in the clinical setting to capture data related to back and leg pain symptoms, function and perceived disability.

BACKGROUND CONTEXT: Low back pain (LBP) is a common and challenging issue. While many patients with LBP respond to treatments such as physical therapy, oral analgesics and spinal injections, others continue to experience symptoms, yet those with degenerative disc disease (DDD) in the absence of significant disc disruption or herniation, scoliosis, stenosis or spondylosis are poor surgical candidates. Recent investigation has revealed spinopelvic misalignment (SPM) as a potential etiology of chronic refractory LBP in individuals with DDD without surgical pathology on lumbar magnetic resonance imaging (MRI).

There was tenderness in the left paravertebral muscle at the lower lumbar level. X-ray and computed tomography revealed congenital scoliosis and an L6 hemivertebra. Short tau inversion recovery magnetic resonance imaging showed a fluid collection at the left L6-S1 facet joint. We performe...

BOSTON (CBS) – Healing your back with the help of yoga. It is a simple solution for people suffering from chronic back pain. A new study, conducted right here in Boston, has found yoga may be an easy answer for some. Judith Zaborowski, who has significant arthritis in her spine, takes yoga. The 74-year-old says the practice helps ease her back pain. (WBZ-TV) “I’m much more comfortable with movement,” Judith explains. Now a new study from Boston Medical Center backs that up. Researchers looked at more than 300 low-income patients with chronic lower back pain. Some took yoga classes designed for back...
