Local ozone (O2-O3) versus corticosteroid injection efficacy in plantar fasciitis treatment: a double-blinded RCT.

PURPOSE: To compare the efficacy of local ozone injection versus corticosteroid in plantar fasciopathy treatment. PATIENTS AND METHODS: This double-blinded randomized trial was performed on 44 adult patients with plantar fasciopathy. One group (23 patients) received local injection of 40 mg methylprednisolone, while a local injection of 3 cc oxygen-ozone solution was performed for the other group (21 subjects). Severity of pain, functional level, and pressure-pain threshold (PPT) were measured before treatment and 1, 4, and 12 weeks after injection using VAS, Foot and Ankle Ability Measure (FAAM) questionnaire, and algometer for PPT, respectively. RESULTS: The majority (65.9%) of the total 44 patients analyzed, were women. Both treatments efficiently relieved patients' pain and improved their functions at 1 and 3 months follow-up time-points. But one week after injection, the improvement in VAS (p<0.001) and FAAM (p<0.001) was significant only in the corticosteroid group. During the first month, VAS (p=0.35) and PPT (p=0.003) were still better in the corticosteroid group. However, FAAM revealed no remarkable difference between the two groups (p=0.083). Eventually, at the third month of follow-up, there was no remarkable preference between the treatments regarding any of the outcome measures (p>0.05). Nevertheless, both methods efficiently improved patients' symptoms, ie, over the 50% of pain reduction and 30% improvement in functional status. CONCLUSION: The present results showed no remarkable superiority between the two groups. In other words, although ozone injection showed a slower efficacy than methylprednisolone, it could be used in plantar fasciitis management as an appropriate alternative.

Comparison between the effects of progesterone versus corticosteroid local injections in mild and moderate carpal tunnel syndrome: a randomized clinical trial.

BACKGROUND: The objective of this study was to compare the short-term effects of progesterone and corticosteroid local injections in the treatment of female patients with carpal tunnel syndrome. METHODS: A randomized clinical trial was used for this study, 60 hands with mild and moderate Carpal Tunnel Syndrome categorized in two groups were used for this study. Patients were treated with a single local injection of triamcinolone acetonide in one group and single local injection of 17-alpha hydroxy progesterone in the other group. Variables such as pain (based on Visual Analogue Scale), symptom severity and functional status (based on Bostone/Levine symptom severity and functional status scale) and nerve conduction study were evaluated before and 10 weeks after the treatments. RESULTS: Ten weeks after treatment, pain severity and median nerve sensory and motor latencies decreased while patients' functional status increased meaningfully in both groups. However, there were no meaningful differences between two groups regarding mentioned variables. Pain severity was milder and duration of post-injection pain was shorter in the corticosteroid group. The rates of patient satisfaction were also meaningfully higher in the corticosteroid group. CONCLUSIONS: Both treatments were effective in the short-term management of mild and moderate disease, clinically and electrophysiologically. There were no significant differences in therapeutic effects between two groups. TRIAL REGISTRATION: Current controlled trials IRCT2013101313442N4.

Does intra articular platelet rich plasma injection improve function, pain and quality of life in patients with osteoarthritis of the knee? A randomized clinical trial.

We designed a randomized clinical trial with control group, to investigate the effects of platelet rich plasma (PRP) on pain, stiffness, function and quality of life in patients with knee osteoarthritis. Patients were randomly divided in two groups. For both groups of participants, therapeutic exercise was prescribed. In the PRP group, two courses of leukocyte rich PRP (5.6 fold higher platelet concentration) with a 4-week interval was injected. For each participant, Western Ontario and McMaster University's Arthritis Index (WOMAC) and the SF-36 questionnaire (Farsi version) were filled at the baseline and 6 months after treatments. Thirty-one patients in the PRP group and 31 patients in the control group were studied. Mean changes of total WOMAC, physical component summery and mental component summery of Short Form-36 in PRP group showed better improvement than control group (P<0.05). This study showed that intra articular PRP knee injection combined with therapeutic exercise can be more effective in pain reduction and improvement of stiffness and quality of life, compared with therapeutic exercise alone.

The pattern of muscle involvement in ulnar neuropathy at the elbow.

OBJECTIVE: To determine the pattern of muscle involvement in patients with ulnar neuropathy at the elbow. MATERIALS AND METHODS: This study evaluated all patients referred for upper limb electrodiagnostic study (EDX) during 2007-2011 and included. patients with clinical signs and symptoms of ulnar neuropathy at the elbow. All patients had nerve conduction studies (NCS) for ulnar neuropathy. Needle electromyography (EMG) of four ulnar innervated muscles, flexor carpi ulnaris (FCU), flexor digitrom profoundus (FDP), first dorsal interosseous (FDI) and abductor digiti minimi (ADM)) was evaluated. RESULTS: During the study period 34 (23 males and 11 females) patients were diagnosed with ulnar neuropathy at the elbow and three of them had bilateral involvement. Muscle involvement by EMG was as follows: FDI: 91.9%, ADM: 91.3%, FCU: 64.9% and FDP: 56.8%. CONCLUSION: In this study, EMG abnormalities of nerve damage were presented more commonly in the FCU muscle than in the FDP in patients with ulnar nerve lesion at the elbow.
