Energy Cost of Slow and Normal Gait Speeds in Low and Normally Functioning Adults
Objective Slow walking speed paired with increased energy cost is a strong predictor for mortality and disability in older adults but has yet to be examined in a heterogenous sample (i.e. age, gender, disease status). The purpose of this study was to examine energy cost of slow and normal walking speeds among low- and normal-functioning adults. Design Adults 20-90 years old were recruited for this study. Participants completed a 10-m functional walk test at a self-selected normal walking speed, and were categorized as low-functioning (LF) or normal-functioning (NF) based upon expected age and gender adjusted average gait speed. Participants completed two successive 3-minute walking stages, at slower than normal and normal walking speeds, respectively. Gas exchange was measured, and energy cost per meter (ml.kg-1.m-1) was calculated for both walking speeds. Results Energy cost per meter was higher (p<0.0001) in the LF group (n=76; female=59.21%; age 61.13±14.68 years (mean±SD)) during the slower than normal and normal (p<0.0001) walking speed bouts compared with the NF group (n=42; female=54.76%; age 51.55±19.51 years). Conclusion Low-functioning adults rely on greater energy cost per meter of walking at slower and normal speeds. This has implications for total daily energy expenditure in low-functioning, adult populations. Corresponding Author: Scott J.

The Feasibility and Effects of Acupuncture on Muscle Soreness and Sense of Well-being in an Adolescent Football Population
Objective To assess the feasibility of performing acupuncture on multiple adolescent athletes in a warm weather, high intensity training environment. To measure perceived effects of acupuncture on delayed-onset muscle soreness (DOMS) and sense of well-being. Design Prospective feasibility study, registered clinical trial (NCT03478800). 42 healthy male participants, ages 13-18 years, were involved in at least one of five treatment days for a total of 147 individual treatment sessions. Fifteen-minute treatments of traditional needle acupuncture were administered at the football field. Time, cost, side effects, and participant to provider ratio were observed. Effect on DOMS and sense of well-being were measured via pre- and posttreatment VAS (0-10) rating analyses. Results Time required by research staff on treatment days, 75 minutes; total cost, $700 temperature range, 21-28°C; largest participant to acupuncturist ratio, 7-10:1. No major side effects occurred; 55% reported minimal side effects such as mild focal numbness or tingling. Overall pre- to posttreatment effect on DOMS (average over 5 days) demonstrated significantly improved posttreatment scores (pre 4.6 ± 2.0; post 2.9 ± 2.2, p<.001). There was no significant effect on sense of well-being (p=0.12). Conclusion Effectively providing acupuncture to multiple adolescent football players in their training environment is feasible with appropriate staff and resources. Despite mild side-effects, treatment was well tolerated. This study provides guidance on acupuncture delivery to other athletes in their training environments.

Hyperbaric oxygen improves functional recovery of the injured spinal cord by inhibiting inflammation and glial scar formation
Background Inflammation and glial scar formation determine the recovery process after spinal cord injury (SCI). Hyperbaric oxygen (HBO) is used as a rehabilitation therapy for various clinical diseases, including SCI. However, the relationship between HBO therapy and inflammation or glial scar is not fully understood. Objective The aim of this study was to investigate the therapeutic effect and molecular mechanism of HBO on SCI. Methods A total of 54 developing female Sprague-Dawley (SD) rats were randomly divided into sham group, SCI group and HBO group, with 18 rats in each group. The model of SCI was established using Allen's method. HBO therapy was administered once a day until the rats were sacrificed. Results The results demonstrated inflammation and glial scar formation are involved in secondary SCI. After HBO treatment, there was a notable improvement of the locomotor function in rats. HBO reduced the inflammatory reaction and glial scar formation by inhibiting inflammation-related factors iNOS and COX-2, and glial scar-related components GFAP and NG2. This process may be achieved by inhibiting AKT and NF-kB pathways. Conclusion HBO effectively promotes the recovery of SCI by inhibiting inflammation and glial scar formation.

Cognitive characteristics associated with device adoption, skill retention, and early withdrawal from a study of an advanced upper limb prosthesis
Objective To examine the role of cognition in device adoption, skill retention, and withdrawal from a study of an advanced upper limb prosthesis (the DEKA Arm). Design T-tests and Wilcoxon rank-sum tests were used to compare test performance among study completers and non-completers. Multivariable regression analyses were used to predict study withdrawal and DEKA Arm skill retention. Results Compared to self-withdrawn participants, those who were withdrawn by study staff performed significantly worse on tests indexing processing speed, set-shifting, and memory encoding. DEKA Arm configuration (transradial, transhumeral, shoulder – based on amputation level), was a stronger predictor of skill retention than neuropsychological test performance. Conclusion Frontally-mediated cognitive skills may influence the successful adoption of the DEKA Arm. DEKA arm configurations at higher amputation levels (e.g., shoulder) appear to be more strongly associated with prosthetic skill retention than users' cognitive status. This may be due to non-cognitive user demands (e.g., device weight) statistically masking the discrete influence of cognitive status on skill retention at higher configuration levels. Neuropsychological assessment warrants consideration as a valuable tool in rehabilitation settings to assist in functional device candidacy evaluations.

Trunk and Head Control During Walking in Patients with Unilateral Vestibular Hypofunction: Effect of Lower Limb Somatosensory Input
Objectives To investigate (1) postural control, especially trunk and head control, in patients with unilateral vestibular hypofunction (UVH) and healthy controls (HCs) during walking on firm and foam surface; (2) the difference between the impact of left and right-side UVH, and correlation between trunk/head control and vestibular function in the patients. Design 13 patients and 13 HCs were recruited. Vestibular function was examined based on the canal paresis value. Participants walked on a treadmill on firm and foam surface. Peak-to-peak trunk (Troll and Tpitch) and head roll and pitch angle (Hroll and Hpitch) were calculated as primary outcome measures. Results In the UVH group but not HCs, Troll was significantly higher on foam than firm surface (p=0.03). Tpitch was significantly higher on foam than firm surface in both groups (p=0.02). Patients had significantly lower Hroll (p=0.03), Hpitch (p=0.02) and lower head-trunk correlation in both medio-lateral (p=0.05) and antero-posterior direction (p=0.03) than those in the HC group. Conclusion Patients with UVH appeared to rely more on lower limb somatosensory input for trunk control especially in the medio-lateral direction compared to HCs. Lower head sway and head-trunk correlation may suggest a more independent and successful head control strategy in patients.

Bilateral Quadriceps Muscle Strength and Pain Correlate with Gait Speed and Gait Endurance Early after Unilateral Total Knee Arthroplasty : A Cross-Sectional Study
Objective The objective of this study was to determine the correlations between objective performance-based physical function, self-reported physical function, quality of life, and gait function at 1 month after unilateral total knee arthroplasty (TKA). Design Cross-sectional data from 195 patients who underwent unilateral primary TKA were analyzed. The isometric knee extensor and flexor strength of both knees, gait parameters, 6 minute walk test (6MWT), timed up-and-go (TUG) test, timed stair climbing test (SCT), knee flexion and extension range of motion (ROM) of surgical knee, Western Ontario McMaster Universities Osteoarthritis Index (WOMAC) pain, stiffness, and functional levels, EuroQol five-dimensions (EQ-5D) questionnaire and visual analog scale (VAS) for knee pain were assessed. Results In bivariate analyses, both postoperative gait speed and gait endurance hadsignificant positive correlations with postoperative peak torque (PT) of the extensor and flexor of both knees, cadence, stride length, and significant negative correlation with TUG, SCT-ascent, SCT-descent, VAS, WOMAC pain, stiffness, and function levels.In the linear regression analyses, postoperative PT of the extensors of both knees and VAS for knee pain were factors correlated with postoperative gait speed and gait endurance. Conclusion Quadriceps muscle strength of both knees and knee pain were important factors correlated with gait function early after TKA. Please address all correspondence to: Bo Ryun Kim, MD. Ph.

Making patients fit for surgery: introducing a four pillar multimodal prehabilitation program in colorectal cancer
Background Considering the relation between preoperative functional capacity and postoperative complications, enhancing a patients functional capacity prior to surgery with a prehabilitation program may facilitate faster recovery and improve quality of life. However, time before surgery is short, mandating a multimodal and high-intensity training approach. This study investigated feasibility and safety of a prehabilitation program for colorectal cancer. Methods Multimodal prehabilitation was offered to patients eligible for participation. They were assigned to an intervention or control group by block randomisation. The prehabilitation program consisted of four interventions: in-hospital high-intensity endurance and strength training, high-protein nutrition, smoking cessation and psychological support. Program attendance, patient satisfaction, adverse events and functional capacity were determined. Results Fifty patients participated in this study (prehabiilitaiton 20, control 30). Program evaluation revealed a high (90%) attendance rate and high level of patient satisfaction. No adverse events occurred. Endurance and/or strength were improved. 86% of patients with prehabilitation recovered to their baseline functional capacity 4 weeks post-operatively, 40% in the control group (p<0.01). Conclusions Multimodal prehabilitation including high-intensity training for colorectal cancer patients is feasible, safe and effective. A randomized controlled trial (NTR5947) was initiated to determine whether prehabilitation may lower morbidity and mortality rates in colorectal surgery.

Evaluating Physician Knowledge of Commonly Prescribed Inpatient Rehabilitation Unit Discharge Medication's Costs: An Observational Study
The objective of this study was to assess physiatrists' knowledge of the cost of medications commonly prescribed at discharge from inpatient rehabilitation units across the spectrum of practice experience from residents to attending physicians. Investigators contacted 92 pharmacies across 4 major regions of the United States (U.S.) and averaged the cash price of each medication. An electronic survey was created highlighting 17 medications in which physicians estimated the cost of a medication per pill and per month for a 30-day supply. Surveys were sent to all ACGME-accredited programs across the U.S.; 43 participants responded to the survey. Most respondents overestimated the cost of the medications chosen for the survey. There was no significant difference between medication cost knowledge and practice experience (p = 0.497) or post-graduate year of training (p = 0.593). This raises awareness that physiatrists may not know the cost of medications they commonly prescribe at discharge, which may have implications on patient medication compliance, quality of care and patient satisfaction.

Clinical Practice Guidelines for the Rehabilitation of Lower Limb Amputation: An Update from the Department of Veterans Affairs and Department of Defense
Between 2015 and 2017, the US Department of Veterans Affairs (VA) and the US Department of Defense (DoD) developed a Clinical Practice Guideline (CPG) for Rehabilitation of Lower Limb Amputation to address key clinical questions. A multidisciplinary workgroup of VA and DoD amputation care subject-matter-experts was formed and an extensive literature search was performed which identified 3,685 citations published from January 2007 through July 2016. Articles were excluded based upon established review criteria resulting in 74 studies being considered as evidence addressing one or more of the identified key issues. The identified literature was evaluated and graded utilizing the National Academies of Science GRADE criteria. Recommendations were formulated following extensive review. Eighteen recommendations were confirmed with four having strong evidence and workgroup confidence in the recommendation. Key recommendations address patient and caregiver education, consideration for the use of rigid and semi-rigid dressings, consideration for the use of microprocessor knees, and managed lifetime care that includes annual transdisciplinary assessments. In conclusion, this CPG utilized the best available evidence from the past 10 years to provide key management recommendations to enhance the quality and consistency of rehabilitation care for persons with lower limb amputation.
