Abstract

Objectives: To estimate the effects of low level laser therapy in combination with a programme of exercises on pain, functionality, range of motion, muscular strength and quality of life in patients with osteoarthritis of the knee.Design: A randomized double-blind placebo-controlled trial with sequential allocation of patients to different treatment groups.Setting: Special Rehabilitation Services.Subjects: Forty participants with knee osteoarthritis, 2-4 osteoarthritis degree, aged between 50 and 75 years and both genders.Intervention: Participants were randomized into one of two groups: the laser group (low level laser therapy dose of 3 J and exercises) or placebo group (placebo laser and exercises).Main measures: Pain was assessed using a visual analogue scale (VAS), functionality using the Lequesne questionnaire, range of motion with a universal goniometer, muscular strength using a dynamometer, and activity using the Western Ontario and McMaster Universities Osteoarthritis (WOMAC) questionnaire at three time points: (T1) baseline, (T2) after the end of laser therapy (three weeks) and (T3) the end of the exercises (11 weeks).Results: When comparing groups, significant differences in the activity were also found (P = 0.03). No other significant differences (P > 0.05) were observed in other variables. In intragroup analysis, participants in the laser group had significant improvement, relative to baseline, on pain (P = 0.001), range of motion (P = 0.01), functionality (P = 0.001) and activity (P < 0.001). No significant improvement was seen in the placebo group.Conclusion: Our findings suggest that low level laser therapy when associated with exercises is effective in yielding pain relief, function and activity on patients with osteoarthritis of the knees.

Abstract

OBJECTIVE:

The aim of this study was to investigate if laser therapy in combination with pulsed electromagnetic field therapy/repetitive transcranial magnetic stimulation (rTMS) and the control of reactive oxygen species (ROS) would lead to positive treatment results for hyperacusis patients.

BACKGROUND DATA:

Eight of the first ten patients treated for tinnitus, who were also suffering from chronic hyperacusis, claimed their hyperacusis improved. Based upon that, a prospective, unblinded, uncontrolled clinical trial was planned and conducted. ROS and hyperacusis pain thresholds were measured.

MATERIALS AND METHODS:

Forty-eight patients were treated twice a week with a combination of therapeutic laser, rTMS, and the control and adjustment of ROS. A magnetic field of no more than 100 microT was oriented behind the outer ear, in the area of the mastoid bone. ROS were measured and controlled by administering different antioxidants. At every treatment session, 177-504 J of laser light of two different wavelengths was administered toward the inner ear via meatus acusticus.

RESULTS:

The improvements were significantly better in the verum group than in a placebo group, where 40% of the patients were expected to have a positive treatment effect. The patients in the long-term follow-up group received significantly greater improvements than the patients in the short-term follow-up group.

CONCLUSION:

The treatment is effective in treating chronic hyperacusis.

Il marchio K-Series è sinonimo di “terapia laser avanzata” e si distingue da tutti i laser che ci sono in commercio grazie all’altissima qualità dei diodi laser, alla massima affidabilità delle apparecchiature dotate di elevato rendimento di potenza e grazie anche alla sua semplicità e praticità d’uso, in quanto la gestione incorporata della fibra ottica e l’alimentazione con batterie ricaricabili, la rendono unica ed incomparabile.

La linea K-Series è composta da due dispositivi: il K-Series 1200 è stato pensato per coloro che vogliono lavorare al top, con la massima potenza di 12 W in emissione continua e 15 W in ISP (Intense Super Impulse), ed è dotato di due lunghezze d’onda, 800 e 970 nm; il K-Series 900 viene consigliato non solo agli esperti in materia laser, ma anche per chi si trova al suo primo approccio con tale tecnologia, ha una potenza di 8 W in emissione continua e 10 W in ISP, ed è dotato di una sola lunghezza d’onda (970 nm)

Terapia rapida ed efficace
Il sistema ISP permette di ottenere una massima efficacia in quanto il laser modula automaticamente i parametri di emissione nel corso del trattamento, garantendo una biostimolazione controllata dei tessuti.

Manipolo zoom
Lo speciale ed unico manipolo zoom permette di selezionare un’area di lavoro ottimale in modo sicuro e pulito. L’ergonomico manipolo con pulsante a pressione permette l’azionamento del laser e la regolazione della potenza in modo semplice per mezzo del rivoluzionario sistema PRC.

Software intuitivo
La K-Series è stata studiata con un sistema intelligente che si avvale di un software intuitivo che garantisce una guida sicura e veloce tramite un comodo touchscreen.

Trattamenti ed applicazioni
Nella medicina moderna l’utilizzo dei laser K-Series per la terapia del dolore acuto e cronico si è rilevato altamente efficace, garantendo tempi di guarigione estremamente ridotti. I laser K-Series offrono la soluzione ideale nei seguenti trattamenti della terapia riabilitativa: cevricalgie, dolori di spalla, edemi post-traumatici, lombalgie e lombosciatalgie, fibromialigie, ferite, piaghe da decupito, artrosi, neuriti, tendiniti, contratture, stiramenti e strappi muscolari, distorsioni, contusioni, borsiti, meta-tarsalgie, fasciti plantari.
