Arthroscopic Debridement Versus Platelet-Rich Plasma Injection: A Prospective, Randomized, Comparative Study of Chronic Lateral Epicondylitis With a Nearly 2-Year Follow-Up.

PURPOSE: The purpose of this prospective, randomized study was to compare the efficacy of autologous platelet-rich plasma (PRP) injections and arthroscopic lateral release in treating chronic lateral epicondylitis (LE). METHODS: Patients who had a clinical diagnosis of LE confirmed by ultrasound (US) were included in this study. A total of 101 patients received arthroscopic release (n = 50) or US-guided PRP injections (n = 51). Outcomes were assessed using a visual analog scale for pain, the Patient-Rated Tennis Elbow Evaluation (PRTEE), and a calibrated hand dynamometer for grip strength. RESULTS: Both patient groups experienced significant improvement in all measures. Between-group comparisons showed a significantly higher value in the PRP group only for grip strength at week 8 (P = .0073); all other significant differences were in favor of arthroscopy: overall pain (P = .0021), night pain (P = .0013), and PRTEE score (P = .0013) at week 104 and grip strength at weeks 24, 52, and 104 (all P < .0001). Consumption of rescue pain medication was not significantly different between the groups. CONCLUSIONS: The present findings suggest that (1) PRP injections and arthroscopic extensor carpi radialis brevis release are both effective in the short and medium term; (2) PRP patients experienced a significant worsening of pain at 2 years; (3) arthroscopic release ensured better long-term outcomes in terms of pain relief and grip strength recovery; and (4) both procedures were safe and well accepted by patients. LEVEL OF EVIDENCE: Level II, prospective comparative study.

Assessment of the ability of wheelchair subjects with spinal cord injury to perform a specific protocol of shoulder training: a pilot study.

BACKGROUND: a regular program of exercises in subjects with spinal cord injury (SCI) can contribute to reduce the risk of upper extremities injuries. METHODS: in this prospective laboratory study we tested the hypothesis that a training machine developed for able-body users is suitable for a shoulder training protocol in 11 paraplegic subjects with SCI. Overall subjects were assessed with the SCIM III, CS, DASH and standard shoulder examination. We set a protocol of shoulder exercises performed with a training machine. Overall subjects were able to perform the protocol but 2 did not complete the exercises n° 6 and 7. The position of the wheelchair during each exercise was recorded. Wheelchair position/loading level were significantly correlated with the protocol n° 2, 3 and 5 as well as BMI/loading level for the exercises n° 5 and 9 and age/loading level for the exercise n° 7. Clinical scores were neither correlated with loading nor with anthropometric data. RESULTS/CONCLUSIONS: FROM THE ANALYSIS OF DATA COLLECTED IN THIS STUDY ARISED THAT: 1) the training machine needs some adjustments for paraplegic subjects, 2) the training protocol was appropriate except for the exercises needing a torso-rotation and 3) the template for wheelchair position may be a valid guide for an optimal paraplegic shoulder training.

Instruments and techniques for the analysis of wheelchair propulsion and upper extremity involvement in patients with spinal cord injuries: current concept review.

The correct functionality of the upper limbs is an essential condition for the autonomy of people with disabilities, especially for those in wheelchair. In this review we focused on the biomechanics of wheelchair propulsion and we described the instrumental analysis of techniques for the acquisition of wheelchair propulsion.
