Effects of tinnitus retraining therapy on patients with tinnitus: a systematic review of randomized controlled trials.

PURPOSE: This review aims to explore the influences of tinnitus retraining therapy (TRT) on patients with tinnitus. METHODS: PubMed, MEDLINE, EMBASE, CINAHL, PEDro, SCOPUS, and Web of Science were screened for randomized controlled trials (RCTs) that explored the effects of TRT on patients with tinnitus from inception to June 30, 2024. The methodological quality of the included RCTs was evaluated using the physiotherapy evidence database (PEDro) scale. RESULTS: Fifteen studies met our eligibility criteria. A total of 2069 patients with tinnitus (mean age 52.93 years; 66% male) were involved in the present review. The quality of the selected studies ranged from 5 to 8 on the PEDro scale, with a median score of 7. TRT did not provide superior effects in treating patients with tinnitus compared to tinnitus masking (TM), tinnitus educational counselling (TED), TRT with open ear hearing aids, Tailor-made notched music training (TMNMT), partial TRT, usual care, and smart TRT. CONCLUSIONS: TRT intervention is considered a treatment option for patients with tinnitus. Combining TRT with other interventions, such as cognitive-behavioral therapy, pharmacotherapy, or tDS, may show even greater efficacy. Additional studies are strongly required to recognize the long-term effects of TRT on tinnitus, determine who most likely would benefit from the intervention regarding tinnitus type and severity, and identify the optimal treatment protocol.

The efficacy of transcranial random noise stimulation in treating tinnitus: a systematic review.

PURPOSE: This review aims to examine the effects of transcranial random noise stimulation (tRNS) on tinnitus and to determine the optimal treatment parameters, if possible. METHODS: A comprehensive search, including MEDLINE, PubMed, EMBASE, CINAHL, SCOPUS, and PEDro, was conducted to determine experiments studying the effects of tRNS on tinnitus from inception to March 1, 2024. The Physiotherapy Evidence Database (PEDro) scale was used to evaluate the quality of the included studies. RESULTS: Seven studies met the eligibility criteria. A total of 616 patients with non-pulsatile tinnitus (mean age 50.93 years; 66% males) were included in this review. The included studies ranged from 3 to 8 out of 10 (median = 7) on the PEDro scale. The results showed that tRNS is an effective intervention in reducing tinnitus symptoms. CONCLUSIONS: The evidence for the effects of tRNS on people with chronic non-pulsatile tinnitus is promising. Administering tRNS with an intensity of 1-2 mA, high-frequency (101-650 Hz), using a 35 cm² electrode size over the auditory cortex and DLPFC, for 20 min with eight sessions may demonstrate the desired tRNS effects. The tRNS stimulation should be contralateral for unilateral tinnitus and bilaterally for bilateral tinnitus. Combining tRNS with other concurrent interventions may show superior effects in reducing tinnitus compared to tRNS alone. Further high-quality studies with larger sample sizes are strongly needed.

Gufoni maneuver for treatment of horizontal canal benign paroxysmal positional vertigo: a systematic review of randomized controlled trials.

PURPOSE: This review aims to investigate the effects of the Gufoni maneuver on horizontal semicircular canal benign paroxysmal positional vertigo (HC-BPPV). METHODS: A comprehensive search, including PubMed, PEDro, REHABDATA, SCOPUS, EMBASE, and Web of Science, was conducted to determine randomized clinical trials (RCTs) studying the effects of the Gufoni maneuver for HC-BPPV from inception to March 1, 2024. The quality of the included studies was estimated using the Physiotherapy Evidence Database (PEDro) scale. RESULTS: Ten randomized controlled trials (RCTs) were included in this review with a total of 1025 HC-BPPV patients (mean age = 58.58 years; 63% female; 55% right-side HC-HBPPV; 49% geotropic HC-BPPV). The included RCTs ranged from 4 to 9 out of 10 (median = 6.5) on the PEDro scale. The included studies showed that the Gufoni maneuver revealed efficacy when compared to the sham maneuver but not when compared to other maneuvers such as the Barbecue roll maneuver, the Appiani maneuver, the Mastoid oscillation, the head shaking, and the modified Gufoni maneuver. CONCLUSIONS: The Gufoni maneuver is considered an option for treating patients with geotropic or apogeotropic HC-BPPV. Precise diagnosis of the BPPV, the subtype of HC-BPPV, symptom duration, history of previous BPPV attacks, the applied methods of maneuver and the proficiency of the clinician performing the maneuver, proper diagnosis, presence of any underlying health conditions are critical for successful treatment. Further studies are strongly warranted.

Semont maneuver for posterior canal benign paroxysmal positional vertigo: a systematic review of randomized controlled trials.

PURPOSE: This review aimed to examine the effects of the Semont maneuver on posterior canal benign paroxysmal positional vertigo (BPPV). METHODS: PubMed, PEDro, SCOPUS, REHABDATA, EMBASE, and Web of Science were searched comprehensively from inception to January 2024. The Physiotherapy Evidence Database (PEDro) scale was employed to evaluate the quality of the selected studies. RESULTS: In total, 18 randomized controlled trials met the eligibility criteria. A total of 2237 participants with BPPV (mean age = 58.10 years) were included in this review. Among them, 37.5% were males, and 58% presented with right-sided BPPV. The included studies ranked from 5 to 9 out of 10 (Median = 7), suggesting good to excellent quality on the PEDro scale. The available literature revealed that the Semont maneuver is effective in improving posterior canal BPPV symptoms. CONCLUSION: The Semont maneuver is considered a standard option for treating posterior canal BPPV, with a high success rate of around 80%. It is suggested as the primary option for managing posterior canal BPPV in individuals who complain of cervical or lumbar problems, severe cardiac or respiratory conditions. Further studies are strongly needed to understand the long-term effects of the Semont maneuver and to identify the recurrence rate.

Effectiveness of brandt-daroff exercises in the treatment of benign paroxysmal positional vertigo: a systematic review of randomized controlled trials.

PURPOSE: This review aims to examine the effects of Brandt-Daroff exercises (BDEs) on individuals with posterior canal Benign Paroxysmal Positional Vertigo (BPPV) and to provide recommendations for future research on this topic. METHODS: PubMed, MEDLINE, PEDro, SCOPUS, REHABDATA, EMBASE, and Web of Science were searched from inception to November 2023. The Physiotherapy Evidence Database (PEDro) scale was used to assess the methodological quality of the included studies. RESULTS: In total, ten randomized controlled trials met our eligibility criteria. A total of 880 individuals with BPPV (63.6% females) were included in this review. The included studies were ranked "good quality" on the PEDro scale. The available literature showed that BDEs do not significantly reduce symptoms or promote recovery in people with posterior canal BPPV compared to other interventions, such as Epley and Semont maneuvers. CONCLUSIONS: The evidence for the effects of BDEs on patients with BPPV is limited. Further high-quality studies with long-term follow-ups are strongly required to investigate the long-term effects of BDEs in posterior canal BPPV, define the optimal application of BDEs, and identify the factors associated with treatment response and recovery.
