Abstract
OBJECTIVE Spinal cord stimulation (SCS) is effective for relieving chronic intractable pain conditions. The Dorsal spInal cord STImulatioN vs mediCal management for the Treatment of low back pain study evaluates the effectiveness of SCS compared with conventional medical management (CMM) in the treatment of chronic low back pain in patients who had not undergone and were not candidates for lumbar spine surgery. METHODS AND MATERIALS Patients were randomized to passive recharge burst therapy (n = 162) or CMM (n = 107). They reported severe pain and disability for more than a decade and had failed a multitude of therapies. Common diagnoses included degenerative disc disease, spondylosis, stenosis, and scoliosis-yet not to a degree amenable to surgery. The six-month primary end point compared responder rates, defined by a 50% reduction in pain. Hierarchical analyses of seven secondary end points were performed in the following order: composite responder rate (numerical rating scale [NRS] or Oswestry Disability Index [ODI]), NRS, ODI, Pain Catastrophizing Scale responder rate, Patient Global Impression of Change (PGIC) responder rate, and Patient-Reported Outcome Measure Information System-29 in pain interference and physical function. RESULTS Intention-to-treat analysis showed a significant difference in pain responders on NRS between SCS (72.6%) and CMM (7.1%) arms (p < 0.0001). Of note, 85.2% of those who received six months of therapy responded on NRS compared with 6.2% of those with CMM (p < 0.0001). All secondary end points indicated the superiority of burst therapy over CMM. A composite measure on function or pain relief showed 91% of subjects with SCS improved, compared with 16% of subjects with CMM. A substantial improvement of 30 points was observed on ODI compared with a CONCLUSIONS This study found substantial improvement at six months in back pain, back pain-related disability, pain-related emotional suffering, PGIC, pain interference, and physical function in a population with severe, debilitating back pain for more than a decade. These improvements were reported in conjunction with reduced opioid use, injection, and ablation therapy. CLINICAL TRIAL REGISTRATION The Clinicaltrials.gov registration number for the study is NCT04479787.

Abstract
Ballet dancers are vulnerable to various stress-related injuries; foot and ankle injuries are the most common. This study determined if the pressure across the foot could be more evenly distributed by wearing various modified technique shoes padded with PPT, Spenco, or Sorbathane, alone or in combinations. A professional ballet dancer performed a jump by taking a single step on his left foot, jumping and landing with his right foot on the force and pressure plates with each modified shoe plus one unmodified shoe. The results of this study revealed: (1) total force cannot be reduced, (2) center of gravity and the majority of the pressure is maintained over the first and second metatarsal heads, and (3) the modified technique shoe can more evenly distribute pressure to the medial arch and away from the toes, metatarsal heads, and heel.
