“…17 In this study, though treatment with IST was given twice weekly, there was an appreciable improvement in the primary and secondary outcome measures. A study by Aiyegbusi et al 16 suggested that twice daily treatment was more effective in augmenting healing than once daily treatment. Further studies are needed to determine if a once daily or twice daily treatment with IST would have an even better effect on the clinical and functional outcome measures.…”

“…The intrasound massager was plugged in, set at the most comfortable intensity for the subject 16 and moved over the affected part of the knee joint in circular motion for 10 minutes with KY-Jelly as a coupling medium. The subjects reported a fine feeling of micromassage and vibrations during the procedure.…”

“…14 Prior studies also found it to be effective and superior to low-intensity pulsed ultrasound in tendon healing when used in animal models. 15,16 The intrasound machine has simplicity of operation as it does not have complicated choices of treatment parameters when compared with other electrophysical gadgets such as TENS. The intensity is increased by turning the radial knob anti-clockwise and can be given at any comfortable intensity for the patient.…”

“…The intensity is increased by turning the radial knob anti-clockwise and can be given at any comfortable intensity for the patient. 16,17 There have been subjective reports of the IST as being beneficial in ameliorating the symptoms associated with knee OA, but there is a dearth of clinical trials to ascertain this. This work was therefore a preliminary study to investigate the therapeutic effects of intrasound in OA knee.…”

Intrasound therapy (IST) has been found to improve healing in acute injuries in animal models but no clinical study has been conducted on chronic degenerative conditions in human subjects. The purpose of this study was to investigate and compare the effects of IST and transcutaneous electrical nerve stimulation (TENS) in the management of knee osteoarthritis. Twenty-four patients were randomly assigned into three groups: IST, TENS, and the control group. Subjects in Group 1 had low-intensity IST for 10 minutes and closed-chain exercises, Group 2 subjects had TENS at a frequency of 100 Hz, a pulse width of 150 µs, continuous mode for 15 minutes and closed-chain exercises, while the control group patients had only closed-chain exercises. Treatment was given for eight weeks, twice weekly. Western Ontario and McMaster Universities Arthritis Index (WOMAC) scores, the distance covered in the 6-minute walk test, and knee range of motion were evaluated before and after the treatment. Data were analyzed using paired t-test and analysis of variance. Level of significance was set at P , 0.05. The clinical outcome measures improved significantly in the posttreatment of the three groups. Subjects in the three groups had significant differences in the mean change in the outcome variables for the WOMAC score (TENS = 29.13 ± 3.83; IST = 28.0 ± 1.72; and control = 13.71 ± 2.52). The post hoc analysis between IST and TENS showed no significant differences but IST had better clinical outcome than TENS.The results of this study suggest that IST may be an alternative to TENS as an adjunct therapy in the management of osteoarthritis of the knee.

| Background: The application time of therapeutic ultrasound is an infrequently studied dosimetric variable that affects tissue repair. Objectives: The aim of this study was to evaluate the effects of different treatment times of therapeutic ultrasound (US) on the organization of collagen fibers in the tendons of rats. Method: Forty Wistar rats were selected (300±45 g), and the rats were divided into five groups (n=8 for each group): Control, without tenotomy or any treatment; tenotomy group, with tenotomy and without treatment; US groups (US1, US2, and US3), subjected to tenotomy and treated with US for one, two, or three minutes per area of the transducer, respectively. The animals were sacrificed on the 12th post-operative day, and the tendons were surgically removed for analyses of the collagen fiber organization by means of birefringence analysis. Results: The collagen fibers exhibited better aggregation and organization in the US3 group compared with the tenotomy group (p<0.05). Conclusions: The findings suggest that US applied for three minutes per treated area improves the organization of collagen fibers during rat tendon repair.Keywords: therapeutic ultrasound; Achilles tendon; physical therapy; collagen; wound healing.

Effects of Low‐Intensity Pulsed Ultrasound in Tendon Injuries

Tendon injuries are the most common soft tissue injuries, caused by tissue overuse and age‐related degeneration. However, the tendon repair process is slow and inefficient due to the lack of cellular structure and blood vessels in the tendon. Low‐intensity pulsed ultrasound (LIPUS) has received increasing attention as a non‐invasive, simple, and safe way to promote tendon healing. This review summarizes the effects and underlying mechanisms of LIPUS on tendon injury by comprehensively examining the published literature, including in vitro, in vivo, and clinical studies. This review reviewed 24 studies, with 87.5% showing improvement. The application of LIPUS in tendon diseases is a promising field worthy of further study.

Abstract: Intrasound therapy has a better morphological effect on the healing tendon than LIPUS and may be an option to consider in the treatment of acute tendon injuries.
