Design Pre- (t1) and post- (t2) exercise therapy experimental design. Setting Hospital. Participants Subjects with chronic low back pain (LBP group) (n=24) and healthy subjects (control group) (n=24) were evaluated. Intervention Exercise program. Main Outcome Measures The control group was evaluated once, and the LBP group was evaluated before (t1) the exercise therapy program and 28 days thereafter (t2). The maximal load lifted, total work, and total power were determined using the PILE test. Continuous-wave near-infrared spectroscopy was used to measure OXY and blood volume during the PILE test. Results The maximal load lifted, total power, and total work were significantly lower in the LBP group (−42%+5%, −46%+6%, and −67%+6% at t1, respectively; P<.05 than the control group. in lbp subjects these parameters improved significantly after exercise therapy program and p at each submaximal power of maximal load lifted t1 oxy blood volume were higher t2 t1. one-half recovery time for was group subjects.> Conclusions The findings in this study suggest that LBP subjects present an impairment in their capacity to deliver oxygen at the level of the erector spinae muscle, which can be partly restored by an exercise therapy program."

Comparison of Muscle and Skin Perfusion Over the Ischial Tuberosities in Response to Wheelchair Tilt-in-Space and Recline Angles in People With Spinal Cord Injury / Yih-Kuen Jan in Archives of Physical Medicine and Rehabilitation, 2013/10 (2013)

Design Repeated-measures and before-after trial design. Setting University research laboratory. Participants Power wheelchair users with SCI (N=20). Interventions Six combinations of wheelchair tilt-in-space and recline angles were presented to participants in a random order. The testing protocol consisted of a baseline 5 minutes sitting with no tilt/recline and 5 minutes positioned in a tilted and reclined position at each of 6 conditions, including: (1) 15° tilt-in-space and 100° recline, (2) 25° tilt-in-space and 100° recline, (3) 35° tilt-in-space and 100° recline, (4) 15° tilt-in-space and 120° recline, (5) 25° tilt-in-space and 120° recline, and (6) 35° tilt-in-space and 120° recline. Main Outcome Measures Muscle and skin perfusion were assessed by near-infrared spectroscopy and laser Doppler flowmetry, respectively. Results Muscle perfusion was significantly increased at 25° and 35° tilt-in-space when combined with 120° recline, and skin perfusion was significantly increased at 3 tilt-in-space angles (15°, 25°, 35°) when combined with 120° recline and at 35° tilt-in-space when combined with 100° recline (P<.05 even in the positions of increased muscle perfusion and skin tilt-in-space combined with recline amount change was significantly lower than> Conclusions Our results indicate that a larger angle of tilt-in-space and recline is needed to improve muscle perfusion compared with skin perfusion. A position of 25° tilt-in-space combined with 120° recline is effective in enhancing muscle and skin perfusion of weight-bearing soft tissues at the ischial tuberosities.

Microcirculatory Assessment of Arterial Below-Knee Stumps: Near-Infrared Spectroscopy Versus Transcutaneous Oxygen Tension—A Preliminary Study in Prosthesis Users / Davy Laroche in Archives of Physical Medicine and Rehabilitation, 2017/6 (2017)  

[article]  inArchives of Physical Medicine and Rehabilitation > 2017/6 (2017) . - pp. 1187–1194 Titre : Microcirculatory Assessment of Arterial Below-Knee Stumps: Near-Infrared Spectroscopy Versus Transcutaneous Oxygen Tension—A Preliminary Study in Prosthesis Users Type de document : Article Auteurs : Davy Laroche ; José-Luis Barnay ; Bastien Tourlonias Année de publication : 2017 Article en page(s) : pp. 1187–1194 Langues : Anglais (eng) Descripteurs : HE Vinci Rééducation et réadaptation Mots-clés : Amputation stumps  Moignons d'amputation  Blood Gas Monitoring  Transcutaneous  Mesure transcutanée des gaz du sang  Spectroscopy  near-infrared  Spectroscopie proche infrarouge Résumé : Objective To examine metrologic properties of near-infrared spectroscopy (NIRS) versus transcutaneous oxygen tension (TcPO2) for microcirculatory assessment of vascular transtibial stumps at the stabilized period of prosthesis fitting, as a preliminary step before exploring its ability to predict stump healing, considering the previously identified limits of TcPO2 (borderline area between 15 and 35mmHg). Design Prospective single-center observational study. Setting University-based rehabilitation center. Participants Individuals with unilateral transtibial amputation for peripheral artery disease, at the definitive stage of prosthesis fitting, able to perform a 2-minute walk test (N=30). Interventions Not applicable. Main Outcome Measures Test-retest, with the stump being evaluated in supine and inclined positions, first by NIRS (tissue saturation index [TSI], oxyhemoglobin, deoxyhemoglobin, and total hemoglobin) and second by TcPO2. Subjects carried out a 2-minute walk test and visual analog scales (wound healing and pain). Results Feasibility and tolerance of NIRS were satisfactory. The reliability of NIRS and TcPO2 values was good (intraclass correlation coefficient >0.7; P<.05 no significant relation was found between nirs and tcpo2. responsiveness vs supine reported>.05). A significant relation between TSI and the 2-minute walk test (r>.49, P<.05 was found.> Conclusions NIRS is painless, complication-free, and feasible, with good reliability. NIRS evaluates others domain than TcPO2 that are more linked to metabolic adaptation. Its capacity to predict stump healing and tolerance to early prosthesis fitting is therefore interesting to estimate in future studies.
