Aquatic exercises are widely used for rehabilitation or preventive therapies in order to enable mobilization and muscle strengthening while minimizing joint loading of the lower limb. The load reducing effect of water due to buoyancy is a main advantage compared to exercises on land. However, also drag forces have to be considered that act opposite to the relative motion of the body segments and require higher muscle activity. Due to these opposing effects on joint loading, the load-reducing effect during aquatic exercises remains unknown...

OBJECTIVES: While generic protocols exist for gait rehabilitation using robotic orthotics such as the Lokomat(®), several settings - guidance, body-weight support (BWS) and velocity - may be adjusted to individualize patient training. However, no systematic approach has yet emerged. Our objective was to assess the feasibility and effects of a systematic approach based on electromyography to determine subject-specific settings with application to the strengthening of the gluteus maximus muscle in post-stroke hemiparetic patients...

This study investigated the protective role of lotus seedpod oligomeric procyanidins (LSOPC) and synbiotics (Bifidobacterium Bb-12 and xylo-oligosaccharide) against high fat and streptozotocin (STZ)-induced diabetes. Administration of LSOPC or synbiotics have no effect on blood glucose in normal mice. Treatments with LSOPC for 12 weeks markedly reduced blood glucose, FFA, endotoxin, GHbA1c and improved glucose homeostasis, lipid metabolism and insulin level. In addition, administration of LSOPC significantly reversed the increase of mTOR and p66Shc in liver, skeletal muscle and white adipose tissue (WAT)...

Cutaneous reflexes are important for rapidly responding to perturbations, correcting limb trajectory and strengthening support. During locomotion, they are modulated by phase to generate functionally appropriate responses. The goal of the present study was to determine if cutaneous reflexes and their phase-dependent modulation are altered with increasing speed and whether this is accomplished at a spinal level. Four adult cats that recovered stable hindlimb locomotion following spinal transection were implanted with electrodes to chronically record hindlimb muscle activity and to electrically stimulate the superficial peroneal nerve to evoke cutaneous reflexes...

Hypermobility syndrome usually causes pain in limbs from extension type injuries. The authors report on a 16-yr-old female adolescent with incapacitating chest pain secondary to extreme hypermobility of the chest. This pain led the patient to see multiple specialists without improvement or diagnosis. Physical examination results revealed a very hypermobile patient who was able to internally rotate her shoulders inward until her elbows touched. This unusual hyperextension maneuver was achieved by holding the shoulders in anteversion with her hands on her hips (see figures in the article)...

This case report highlights a novel approach to strengthening the repair of a split peroneus brevis tendon tear with a peroneus quartus muscle autograft. We describe a 51-year-old woman with a longitudinal split tear of the peroneus brevis tendon confirmed by magnetic resonance imaging. Intraoperatively, a peroneus quartus muscle was appreciated, resected, and used as an autograft in the repair of the peroneus brevis tendon. Use of a peroneus quartus muscle as an autograft in peroneal tendon repair has not been documented in the literature, to our knowledge...

Persons unable to exercise due to old age, immobility or medical condition may develop low bone density, decline in muscle contraction, blood pooling or clot. Due to musculoskeletal fragility caution is required in bone and muscle strengthening. Similarly, caution is required to use anticoagulant drug to prevent blood clot due to side effect, and compression devices are not as effective as drug. This paper presents a transcutaneous muscle fiber excitation system adaptable for use in seated, walking or lying position...

Interventions that can produce targeted brain plasticity after human spinal cord injury (SCI) are needed for restoration of impaired movement in these patients. In this study, we tested the effects of repetitive cervicothoracic transspinal stimulation in one person with cervical motor incomplete SCI on cortical and corticospinal excitability, which were assessed via transcranial magnetic stimulation with paired and single pulses, respectively. We found that repetitive cervicothoracic transspinal stimulation potentiated intracortical facilitation in flexor and extensor wrist muscles, recovered intracortical inhibition in the more impaired wrist flexor muscle, increased corticospinal excitability bilaterally, and improved voluntary muscle strength...

Aging is associated with an unavoidable decline in muscle mass, known as sarcopenia, leading to neuromuscular declines, muscle weakness, and subsequent disability. One particular measure utilized by rehabilitative professionals in evaluating functional declines in older persons is sit-to-stand (STS) capacity. The purpose of this investigation was to determine the role of activation intensity requirements of the thigh musculature in limiting a multi-joint STS endurance task. To do so, surface EMG signals of the quadriceps femoris (QF) and hamstrings (biceps femoris; BF) and their co-activation ratios (H:Q) were collected in young (18-35 years; n = 12) and older (60-75 years; n = 12) adult participants who repeatedly stood from a seated position until exhaustion...

The Finnish recommendations for health-enhancing physical activity (PA) for adults (≥18 years) recommend: (i) ≥150 minutes of moderate to vigorous-intensity physical activity (MVPA); and (ii) activities that develop muscle strength and balance ≥2 days per week. However, adherence to these recommendations among the Finnish adults is currently unknown. This paper reports on the self-reported adherence to the PA recommendations and associations with sociodemographic factors among Finnish adults. Data were used from the Finnish 'Regional Health and Well-being Study'...
