Of the many bizarre complications of administration of the COVID 19 vaccine, adhesive capsulitis is almost unheard of, although shoulder injury related to vaccine administration, which by definition has symptom onset within 48 hrs and is caused by faulty injection technique, has been rarely reported. Nine cases of adhesive capsulitis, five males and four females with a mean age of 48.7 ± 12.7 yrs, presenting within 1 mo of intramuscular Covishield vaccine on the ipsilateral deltoid and fulfilling the standard UK FROST Multicenter Study diagnostic criteria are reported. The mean time interval from vaccination until symptom onset was 12.3 ± 3.1 days, and mean symptom duration was 9.4 ± 2.4 wks. Conventional treatment with nonsteroidal anti-inflammatory drugs, followed by intra-articular steroid injection coupled with suprascapular nerve steroid block, improved the pain score and range of movement in 8 wks. The exact pathogenesis remains an enigma, although mechanisms such as local spread via deltoid muscle microvasculature, nerves, or shoulder injury related to vaccine administration causing secondary adhesive capsulitis have been hypothesized. While adhesive capsulitis is a very common diagnosis in the physiatric outpatient setting, the possible association with Covishield vaccination, the Indian version of the Oxford AstraZeneca recombinant ChAdOx1 nCoV-19 vaccine, is almost absent in existing literature and hence likely to be missed by clinicians, which necessitates this report.
IntroductionPlantar fasciitis is a degenerative condition of the plantar fascia that leads to heel and sole pain. Physical modalities, physiotherapy, medication, and orthoses have been tried before as treatments. Extracorporeal shockwave therapy (ESWT) and the injection of autologous platelet-rich plasma (PRP) are generally effective in the treatment of plantar fasciitis, which might be resistant to other conservative measures. The present study compares the efficacy of ESWT and PRP injection in respect of symptomatic relief, functional improvement, and change in plantar fascia thickness (PFT).
MethodsSeventy-two patients were enrolled and randomized into two groups. Patients in the first group received ESWT, whereas patients in the second group received PRP injections. Patients were evaluated using the Visual Analog Scale (VAS) and the American Orthopedic Foot and Ankle Society (AOFAS) score, along with PFT measurement (using ultrasonography) before the treatment and at days 15, 30, and 90 after the treatment. The X 2 test was used to compare qualitative variables, and the paired T-test was used to evaluate quantitative data. Quantitative variables had a normal distribution with a standard deviation, and the significance level was set at P-value=0.05.
ResultsOn day 0, the mean VAS of the ESWT and PRP groups were 6.44±1.11 and 6.78±1.17, respectively (p=0.237). On day 15, the mean VAS of the ESWT and PRP groups were 4.67±1.45 and 6.67±1.35, respectively (p<0.001). At day 30, the mean VAS of the ESWT and PRP groups were 4. 97±1.46 and 4.69±1.39, respectively (p=0.391). On day 90, the mean VAS of the ESWT and PRP groups were 5.47±1.63 and 3.36±0.96 (p<0.001). On day 0, the mean PFTs of the ESWT and PRP groups were 4. 73±0.40 and 5.19±0.51, respectively (p<0.001). At day 15, the mean PFT of the ESWT and PRP groups were 4.64±0.46 and 5.11±0.62, respectively (p<0.001) which changed to 4.52±0.53 and 4.40±0.58 at day 30 (p<0.001), and to 4.40±0.50 and 3.82±0.45 at day 90 (p<0.001).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
