Roux-en-Y versus one-anastomosis gastric bypass (RYSA study): weight loss, metabolic improvements, and nutrition at 1 year after surgery, a multicenter randomized controlled trial.

Objective: Although it has been suggested that one-anastomosis gastric bypass (OAGB) is metabolically superior to the "gold standard," i.e., Roux-en-Y gastric bypass (RYGB), there is little robust evidence to prove it.

Tendon Length, Calf Muscle Atrophy, and Strength Deficit After Acute Achilles Tendon Rupture: Long-Term Follow-up of Patients in a Previous Study.

Background: In this prospective study, we used magnetic resonance imaging (MRI) to assess long-term Achilles tendon length, calf muscle volume, and muscle fatty degeneration after surgery for acute Achilles tendon rupture.

Methods: From 1998 to 2001, 60 patients at our center underwent surgery for acute Achilles tendon rupture followed by early functional postoperative rehabilitation. Fifty-five patients were reexamined after a minimum duration of follow-up of 13 years (mean, 14 years), and 52 of them were included in the present study.

Soleus Atrophy Is Common After the Nonsurgical Treatment of Acute Achilles Tendon Ruptures: A Randomized Clinical Trial Comparing Surgical and Nonsurgical Functional Treatments.

Setting: An outpatient centre-based setting.

Augmented compared with nonaugmented surgical repair of a fresh total Achilles tendon rupture. A prospective randomized study.

Background: Augmented and nonaugmented techniques have been used for the operative repair of a fresh complete Achilles tendon rupture. Augmented techniques have been favored for their stronger pullout strengths but have been avoided because of the risk of wound complications. If proven to be equally good, the nonaugmented technique would be the method of choice.

Early functional treatment versus early immobilization in tension of the musculotendinous unit after Achilles rupture repair: a prospective, randomized, clinical study.

Background: The aim of our prospective, randomized, clinical study was to compare two postoperative regimens after Achilles rupture repair and determine whether early functional treatment will give a better result than early immobilization in tension of the musculotendinous unit.

Methods: Fifty patients with acute Achilles tendon rupture were randomized postoperatively to receive either early movement of the ankle between neutral and plantar flexion in a brace for 6 weeks or Achilles tendon immobilization in tension using a below-knee cast with the ankle in a neutral position for 6 weeks. Full weight bearing was allowed after 3 weeks in both groups.

Temporomandibular disorders, occlusion, and neck pain in subjects with facial pain: a case-control study.

The etiology of facial pain is multifactorial. Based on the results of a questionnaire included in the study of the 1966 Northern Finland Birth Cohort, performed in 1997-98, we found an association of facial pain with subjective symptoms of temporomandibular disorders (TMD), neck pain and with occlusal factors reported by 5,696 subjects. The aim of the present study was to examine these associations clinically.

Risk factors for recurrent stress fractures in athletes.

Our aim was to identify factors predisposing athletes to multiple stress fractures, with the emphasis on biomechanical factors. Our hypothesis was that certain anatomic factors of the ankle are associated with risk of multiple stress fractures of the lower extremities in athletes. Thirty-one athletes (19 men and 12 women) with at least three separate stress fractures each, and a control group of 15 athletes without fractures completed a questionnaire focusing on putative risk factors for stress fractures, such as nutrition, training history, and hormonal history in women.

Delayed-onset muscle soreness and motor performance of the upper extremity.

The purpose of this study was to examine the effects of delayed-onset muscle soreness after a strength-training session on the motor performance of the upper extremities, including the reaction time, speed of movement, tapping speed and coordination. In addition, muscle strength, electromyographic (EMG) activity, creatine kinase (CK) and soreness responses were measured. The study was a randomised cross-over intervention study, where 30 subjects (divided into two groups, A and B) performed a 1-h muscle strength-training session of the upper extremities, and the responses were measured 48 h after that.

Strength training for 1h in humans: effect on the motor performance of normal upper extremities.

It has been found that one session of intense muscle strength training decreases muscle strength temporarily and causes neuromuscular fatigue in the trained muscles, but little attention has been given to the effects of neuromuscular fatigue on the other components of motor performance. The purpose of this study was to examine in normal healthy volunteers the effects of a 1-h strength training session on the motor performance of the upper extremity, including reaction time, speed of movement, tapping speed and coordination. Group of 30 healthy female volunteers, aged 29-47 years, were randomly divided into sub-groups, (A and B, n = 15 per group).

A 10-week strength training program: effect on the motor performance of an unimpaired upper extremity.

Objective: Muscle strength training is one of the most common therapy methods in physical therapy programs, and the usual goal of this treatment is to improve muscle strength. Little attention has been paid, however, to the effects of strength training on the other components of motor performance. This study examined the effects of a 10-week strength training program on the motor performance of the hand, including reaction time, speed of movement, tapping speed, and coordination in normal healthy volunteers.

The effect of strapping on the motor performance of the ankle and wrist joints.

The purpose of this study was to examine the effect of strapping on different components of motor performance of wrist and ankle joints. The subjects were 14 healthy volunteers (12 females, two males), aged 21-33 years, with no known previous injuries of the ankle and wrist joints. The measurements were made with the HPM/BEP system and Isokinetic Lido Active Multi-joint system.

Isokinetic evaluation of calf muscle performance after Achilles rupture repair.

The purposes of this study was 1) to assess the plantar flexion and dorsiflexion peak torques (PT) of the ankles at 30, 90 and 240.. s-1 in 101 patients (86 men, 15 women) who had been operated on for unilateral, complete closed Achilles tendon (AT) rupture at Oulu University Hospital, Oulu, Finland, in the period 1987-1992, 2) to determine whether comparison between the legs shows any impairment, 3) to study whether the weakness is speed-dependent, 4) to determine at what angular displacement of the ankle the weakness is manifested, 5) to study how the results correlate with age, type of operation and follow-up time.

Quantification of muscle strength in recessive myotonia congenita.

In order to quantify muscle strength in recessive myotonia congenita (MC) the peak and average peak torques (PT and APT, respectively) of knee flexion and extension of 19 MC patients were measured at speeds of 60 degrees/s and 200 degrees/s. Muscle endurance was measured at a speed of 200 degrees/s. No differences were found between the patient and control groups for PT and APT values for flexion at the high speed, nor were there any differences between the patients and the controls for PT and APT measured at the low speed for knee flexion and extension or muscle endurance at the high speed.
