SUMMARY This study investigated changes in knee extensor and flexor strength of 17 mildly involved adolescents with cerebral palsy response to an eight‐week isokinetic strength‐training program. Peak torque work were used as outcome measures. Subsequent gross motor function walking efficiency evaluated. The significant gains 21 25 per cent observed similar magnitude those previously reported for able‐bodied individuals. A number subjects showed increase ability. However, velocity unchanged....

The relationships between isometric and isokinetic-concentric knee extensor flexor strength, quadriceps hamstring cross-sectional area (CSA) were determined in young (n = 13, M 24.5y) elderly 12, 70.7y) men. Quadriceps CSA was by computed tomography. Knee strength at 0°/s 120°/s on a kin-corn isokinetic dynamometer. Compared to the men, men had significantly smaller muscles weaker (22–32%) flexion extension both angular velocities. Strength:CSA ratios similar 0°/s, but decreased for...

One hundred sixty patients (mean age, 68 ± 8 years) having primary total knee arthroplasty were assigned randomly to two rehabilitation programs: (1) clinic-based provided by outpatient physical therapists; or (2) home-based monitored periodic telephone calls from a therapist. Both programs emphasized common home exercise program. Before surgery, and at 12 52 weeks after no statistically significant differences observed between the clinic- groups on any of following measures: score Knee...

Study Design Prospective intertester reliability study investigating the ability of 2 therapists to agree on a low back pain diagnosis using examination techniques and classification system described by McKenzie. Objectives To investigate agreement in determining McKenzie diagnostic syndromes, subsyndromes, presence, relevance spinal deformities. Background Reliability approach for categories is unclear. Previous studies have been characterized inconsistency test protocols, criterion...

Variable definitions of outcome have been used in the past to assess results after total joint replacement surgery. These differ their approach measurement but all must be valid (they measure what they are designed measure), reliable (the consistently produce same score), and responsive (able detect changes that may occur during a period). Responsiveness is crucial distinguish those patients who benefit from procedure do not, more test will theoretically able identify subtle patient status....

One hundred patients with osteoarthritic knees were randomized either to have their patella resurfaced or not using the same total knee replacement. These assessed preoperatively and a minimum 2 years postoperatively disease-specific (Knee Society Clinical Rating System) functional capacity (30 second stair climbing flexor extensor torques) outcome measures. Two in group required reoperation because of anterior pain. At years' followup, had significantly less pain better torques than did...

This study compared the strength of knee extension and flexion muscles in groups young elderly women under two conditions: eccentric exercise which were lengthened while subjects tried to resist an external force, versus concentric contractions shortened. Twenty-six females, aged 20 29 (Mean 25 ± 3 SD), 26 women, 66 89 73 6 tested at angular velocities movement, 45° 90°ls, on a kinCom isokinetic dynamometer. Elderly had significantly lower peak average torque values all comparisons with...

The purpose of this study was to determine the relationships among measures knee extensor and flexor strength, walking efficiency, gross motor abilities in adolescents with cerebral palsy. Seventeen (mean age 16 ± 3 years) completed isokinetic tests for extension flexion (concentric–no pause–eccentric muscle action cycles at 90-degrees per second angular velocity) efficiency (Energy Expenditure Index or EEI) on two occasions, 1 week apart. Gross ability assessed using components Motor...

Background Despite a lack of evidence for their effectiveness, functional knee braces are commonly prescribed to patients after anterior cruciate ligament (ACL) reconstruction. Purpose This trial was conducted compare postoperative outcomes in using an ACL brace and neoprene sleeve. Hypothesis Patients will have superior than those Study Design Randomized controlled clinical trial; Level evidence, 1. Methods One hundred fifty were randomized receive (n = 76) or sleeve 74) at 6-week visit...

The primary objective of the present study was to compare effect a neoprene sleeve on knee joint position sense during sitting open kinetic chain test and supine closed test. Young (24 2 years old), healthy subjects (18 men 18 women) performed angle replication tests extension (sitting) leg press (supine with an axial load 15% body weight) before after application over dominant knee. improvement in ability replicate angles (sleeve effect) significantly less (0.3° 1.4°) than (1.2° 1.1°)....

Objective. To evaluate the effects of a functional knee brace specifically designed for patients with varus gonarthrosis on measures proprioception and postural control.

Abstract Neuromyelitis optica (NMO) is a severe inflammatory demyelinating disease of the central nervous system with exacerbations involving optic nerves, spinal cord, or both. This study explores utility maintenance plasma exchange (mTPE) as therapy in patients relapsing, corticosteroid‐refractory, NMO. retrospective case series presents data on who were diagnosed NMO using currently accepted criteria. These refractory to high‐dose corticosteroids and received mTPE. Seven met criteria for...

To determine the effectiveness of balance exercises in acute post-operative phase following total hip arthroplasty or knee arthroplasty.Patients who had (n = 30) 33) were seen their residence 1-2 times per week for 5 weeks. At first home visit, patients randomly assigned to either typical (TE, n plus (TE + B, exercise groups. The TE group completed seven surgery-specific joint range-of-motion and muscle strengthening exercises, while B three exercises. Patients assessed before weeks after...

The authors report the results of a prospective randomized clinical trial using continuous passive motion after total knee arthroplasty. One hundred twenty patients were assigned randomly to one treatment group: No (Group I), from 0 °to 50 °and increased as tolerated II), and 70 110 °(Group III). was initiated in recovery room maintained for maximum 24 hours at which point all began identical postoperative physiotherapy regimens. Patients assessed preoperatively, during their hospital stay,...

Although previous investigators have observed that knowledge of performance via visual feedback tends to enhance during an isokinetic test, the time frame over which remains advantageous is unclear. The purpose this study was compare knee extensor torques produced by and no groups on three occasions, completed a 2-week period, at 4 weeks after third test. Healthy, sedentary subjects were each randomly assigned either or group (N = 10 males females per group). Visual consisted viewing...

Although a relative preservation of eccentric (ECC) strength with age has been reported previously, this phenomenon not studied in lower leg muscles. Concentric (CONC) and ECC plantar (PF) dorsiflexion (DF) healthy active older women (OW; n = 16, 67 ± 4 years) younger (YW; 27 were studied. Passive resistive torque the flexors average rate development (RTD)for both DF PF also measured. The OW had CONC peak torques that 74% 89% YWfor DF, whereas 97% 100% YW. patterns almost identical for...

The purpose of this study was to compare dynamic pushup (DPU) and plyometric push-up (PPU) training programs on 2 criterion measures: (a) the distance achieved a sitting, 2-handed medicine ball put, (b) maximum weight for 1 repetition chest press. Thirty-five healthy women completed 18 sessions over 6-week period, with time repetitions matched DPU (n 5 17) PPU 18) groups. Dynamic push-ups were from knees, using 2-second-up‐2-second-down cadence. Plyometric also subjects allowing themselves...
