Effects of elastic resistance exercise after total knee replacement on muscle mass and physical function in elderly women with osteoarthritis: A randomized controlled trial OBJECTIVE Knee osteoarthritis (KOA) and age are associated with high sarcopenia risk, especially in patients who have received total knee replacement (TKR). The purpose of this study was to identify the effects of elastic resistance exercise training (RET) after TKR on muscle mass and physical outcomes in older women with KOA. DESIGN Sixty older women who received unilateral primary TKR surgery were randomized to an experimental group (EG), which received 12 weeks of postoperative elastic RET, or a control group (CG), which received standard care. The outcome measures included physical function performance (i.e., Timed Up & Go [TUG], gait speed [GS], forward reach, single-leg stance, timed chair rise), appendicular lean mass (ALM), and the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC). The assessment time points were 2 weeks prior to surgery (T0), 1 month after surgery (T1; before RET), and 4 months after surgery (T2; upon completion of RET). RESULTS After 12 weeks of postoperative elastic RET, the EG exhibited a significantly greater change in ALM (mean difference [MD], 0.81 kg; P = .004) than the CG. Elastic RET also exerted significant effects on TUG and GS with MDs of 0.28 m/s (P < .001) and -2.66 s (P < .001), respectively. CONCLUSION A 12-week elastic RET program after TKR exerted benefits on muscle mass, mobility, and WOMAC functional outcomes in older women with KOA.

Disparities in Health Care for Hispanic Patients in Physical Medicine and Rehabilitation in the United States: A Narrative Review In the United States, the number of people with Hispanic backgrounds is rapidly increasing. This growth, along with other factors, may put them at increased risk for healthcare disparities. Thus, Physical Medicine and Rehabilitation (PM&R) should evaluate disparities in health services through the lens of the evidence base. To our knowledge, this is the first review describing the literature on healthcare disparities for Hispanic patients in the field of PM&R. This review explores healthcare utilization, risk factors, access, and health conditions specific to Hispanic populations. Articles used in this narrative review were collected over a 10-year span (2009-2018) from online databases. Our findings highlight disparities across common conditions and injuries in the PM&R literature, including post stroke rehabilitation, hip fracture treatment and rehabilitation, spinal cord injury, and traumatic brain injury. Our review suggests that Hispanic patients may be at risk for worse outcomes following these conditions, due to low access to rehabilitation services and disparities in the referral process. Similar results are reported for pain management and Parkinson’s disease. As we strive to provide optimal care to an increasingly diverse patient population, researchers and clinicians must consider effects of race and ethnicity on access to and utilization of rehabilitation services.

Role of Instruction Adherence During Highly Structured Robotic Arm Training on Motor Outcomes for Individuals after Chronic Stroke The aim of this study was to examine the effects of instruction adherence on upper extremity motor outcomes after highly structured intervention. A secondary data analysis was completed using mixed linear modelling design. Thirty chronic stroke survivors with moderate-to-severe arm impairment were assigned explicit movement instructions and completed 12 robotic therapy sessions over four weeks. Instruction adherence was measured weekly using the Manipulation Check Questionnaire (MCQ). Motor outcomes were measured at baseline, discharge, and at 4-week follow-up using the Fugl-Meyer Assessment-Upper Extremity (FMA-UE) and Wolf Motor Function Test–Functional Ability Scale (WMFT-FAS). There were no effects of adherence-related variables on upper extremity motor outcomes (p values > .2). Participant scores improved for both FMA-UE and WMFT-FAS from baseline to follow-up (p values < .001). Participants improved motor function after 12 weeks of robotic training, however, instruction adherence did not affect motor improvement. Adherence to explicit information may play a limited role in motor learning for stroke survivors with moderate-to-severe arm impairment during highly structured training protocols.

Multiple Accessory Lower Limb Muscles Identified Using Ultrasonography in An Asymptomatic Individual No abstract available |
Effects of Upper Limb Loss or Absence and Prosthesis Use on Postural Control of Standing Balance Objective Persons with upper limb loss or absence (ULL/A) experience a high prevalence of falls. While upper limb prostheses help perform upper extremity tasks, fall likelihood increases by six times with prosthesis use. The effects of ULL/A and prosthesis use on postural control are poorly documented. Design Static posturography characterized postural control of standing balance between persons with unilateral ULL/A not wearing a prosthesis and wearing either a customary prosthesis or prosthesis that matched the mass, inertia, and length of their sound limb. Able-bodied controls were also compared to persons with unilateral ULL/A not wearing a prosthesis. Center-of-pressure anterior-posterior range, medial-lateral range, and sway area was measured, as well as weight-bearing symmetry. Results Persons with ULL/A display greater standing postural sway than controls. While wearing a prosthesis improved weight-bearing symmetry, this condition increased postural sway, which was pronounced in the medial-lateral direction. Conclusion The presence of ULL/A increased postural control demands as reflected in greater postural sway than able-bodied individuals, which was further exacerbated with the use of prosthesis. Results suggest that ULL/A and prosthesis use may affect the internal models that guide motor commands to maintain body center-of-mass position equilibrium. The relatively greater postural control demands might help explain the increase fall prevalence in this patient group.

Variability of Steady State Oral Baclofen Dosing in Pediatric Patients with Cerebral Palsy The primary objective of this study was to identify oral baclofen dosing variability at steady state based on weight and Gross Motor Functional Classification System (GMFCS) level using a retrospective cross-sectional study design. The medical records of 500 pediatric aged patients (age 1-21) were reviewed to obtain 144 pediatric patients who met inclusion criteria. One way ANOVA tests revealed increasing mean doses in baclofen (in mg/kg) with higher GMFCS levels (p=0.001). Post-hoc Tukey analysis showed patients with higher ambulatory ability (GMFCS I-II) received a lower total daily dosage than did patients with less ambulatory ability (GMFCS III-V). A moderate correlation was observed with increasing oral baclofen dose as weight increased (r=0.43, p<0.0001). Due to the variability in dosing between GMFCS levels, prescribing oral baclofen for pediatric patients with CP may not follow the traditional model of weight-based dosing seen in other pediatric conditions.
