92Topical NSAIDs Are Effective for Tennis Elbow Without Oral Side Effects
Cochrane Database of Systematic Reviews (2013) · Pattanittum P, Turner T, Green S, Buchbinder R
This Cochrane systematic review analyzed 15 trials with 759 participants to evaluate the effectiveness of topical and oral NSAIDs for treating lateral elbow pain, commonly known as tennis elbow. The review found that topical NSAIDs were significantly more effective than placebo for short-term pain relief, with a number needed to treat of 7, meaning that for every 7 patients treated with topical NSAIDs, one additional patient experienced significant pain relief compared to placebo. Participants using topical NSAIDs also reported better overall treatment effectiveness at 28 days. Adverse effects from topical NSAIDs were minimal, with only mild skin reactions such as rash reported in 2.5% of users, compared to 1.3% with placebo. For oral NSAIDs, the evidence was conflicting. One trial found significant pain improvement compared to placebo while another found no difference, and neither showed improvement in function. Notably, oral NSAIDs were associated with an increased risk of gastrointestinal side effects, and several participants had to discontinue treatment due to GI issues. The review found no trials that directly compared topical and oral NSAIDs head to head. These findings support the use of topical NSAIDs as a first-line option for conditions like tennis elbow, where the anti-inflammatory medication can be delivered directly to the injured tendon without exposing the gastrointestinal system to the risks associated with oral NSAIDs. For patients who do use oral NSAIDs, the evidence suggests limiting duration to the short term.

21Low-Level Laser Therapy Effectively Treats Tennis and Golferâs Elbow
Journal of Clinical Laser Medicine & Surgery (1998) · Z. Simunovic, T. Trobonjaca, Z. Trobonjaca
This multicenter, double-blind, placebo-controlled study evaluated the effectiveness of low-level laser therapy (LLLT) in 324 patients with medial (n=50) or lateral (n=274) epicondylitis. Patients received either trigger point laser therapy, scanner-based laser therapy, or a combination of both. The combination treatment resulted in complete pain relief and improved functional ability in 82% of acute and 66% of chronic cases. The study highlights the importance of proper dosing, technique, and therapist expertise in optimizing LLLT outcomes for epicondylitis.

49Muscle Damage from Sustained Isometric Contractions
European Journal of Applied Physiology (2017) · Morgan DL, Proske U, Allen TJ
This study investigated how muscle damage accumulates during sustained isometric contractions of the human elbow flexors. Results showed that the majority of damage occurred during the plateau phase of the contraction, not the initiation or relaxation phases. Although mechanical strain was continuous, pain and muscle tenderness did not appear until later, during movement or physical activity. These findings reinforce the concept that tissue injury from isometric strain may not be perceived until after the event, aligning with delayed symptom onset in joint conditions like bursitis.

4Effects of Far-Infrared Radiation Lamp Therapy on Recovery from Muscle Damage
European Journal of Sport Science (2023) · Trevor C. Chen, Yuh-Chuan Huang, Tai-Ying Chou, Sheng-Tsung Hsu, Mei-Yen Chen, Kazunori Nosaka
This study examined the effects of far-infrared radiation (FIR) lamp therapy on muscle damage and proprioception following eccentric exercise of the elbow and knee flexors. In a controlled experiment, 24 sedentary women received either FIR therapy or a sham treatment. The FIR group showed significantly faster recovery in muscle strength and proprioception, reduced muscle soreness by 55-60%, and lowered peak plasma creatine kinase activity by 45-89%. FIR therapy accelerated recovery from exercise-induced muscle damage more effectively than previously studied interventions.

12Shortwave Diathermy Enhances Recovery in Lateral Epicondylitis
Journal of Bodywork & Movement Therapies (2020) · A. Babaei-Ghazani, B. Shahrami, E. Fallah, T. Ahadi, B. Forough, S. Ebadi
This study evaluated the effectiveness of continuous shortwave diathermy (SWD) in treating chronic lateral epicondylitis (tennis elbow). Fifty patients were assigned to either an SWD + exercise group or a sham diathermy + exercise group. The SWD group received 15 minutes of 40-60 W continuous SWD along with specific exercises. Pain, function, and grip strength were measured at baseline, after 5 and 10 treatment sessions, and at 3 months. The SWD group showed significantly greater improvements in all outcomes compared to the control group. These findings suggest that SWD enhances pain relief and functional recovery in lateral epicondylitis.

85Corticosteroid Injections Help Short Term but Worsen Outcomes Long Term
Lancet (2010) · Coombes BK, Bisset L, Vicenzino B
This systematic review of 41 randomized controlled trials with 2,672 participants evaluated the clinical efficacy and safety of injection therapies for tendinopathy. The study found that corticosteroid injections reduced pain in the short term (within 4 weeks) compared to other interventions, showing a large effect size. However, this benefit was reversed at intermediate term (13 to 26 weeks) and long term (52 weeks and beyond). For example, in treating lateral epicondylalgia (tennis elbow), corticosteroid injections showed a large positive effect in the short term but actually performed worse than no intervention at all by the intermediate and long-term follow-up. This means that patients who received corticosteroid injections were ultimately worse off than if they had done nothing. The study also found that the short-term efficacy for rotator cuff tendinopathy was not clear. Among 991 participants who received corticosteroid injections, one case of tendon rupture was reported. These findings demonstrate that while corticosteroid injections provide temporary pain relief, they do not support long-term healing and may actually delay recovery. The reversal of benefit over time is consistent with the concern that pain masking leads to further tissue damage, as patients overuse the injured area while unable to feel the warning signs of strain.

62Early Motion After Rotator Cuff Repair May Increase Retear Risk
Journal of Shoulder and Elbow Surgery (2017) · Saltzman BM, Zuke WA, Go B, Mascarenhas R, Verma NN, Cole BJ, Romeo AA, Forsythe B
This systematic review analyzed 9 meta-analyses comparing early motion versus delayed motion rehabilitation after arthroscopic rotator cuff repair. The researchers found no clear superiority in functional outcomes for either approach. While early motion provided slightly better range of motion in the first year, there was concern that it may lead to higher retear rates, particularly in patients with larger tears. Tendon healing results either showed no difference or favored delayed motion. The findings suggest that rushing back to movement after rotator cuff repair may increase the risk of reinjury without providing meaningful long-term benefits.

64Delayed Rehabilitation Produces Better Healing for Larger Rotator Cuff Tears
Journal of Shoulder and Elbow Surgery (2012) · Cuff DJ, Pupello DR
This randomized controlled trial enrolled 68 patients with full-thickness supraspinatus tears to compare early passive motion versus delayed rehabilitation after arthroscopic rotator cuff repair. While both groups showed similar overall outcomes, the delayed rehabilitation group demonstrated significantly better tendon healing rates, particularly for larger tears. The study found that early motion did not improve functional outcomes and that a more conservative approach with delayed movement allowed better tissue repair. These results support the concept that giving the rotator cuff adequate rest after injury or repair promotes better healing than rushing into exercise.

65Continuous Cold Therapy Reduces Pain After Shoulder Surgery
Journal of Shoulder and Elbow Surgery (2001) · Singh H, Osbahr DC, Holovacs TF, Cawley PW, Speer KP
This prospective randomized study evaluated the effectiveness of continuous cryotherapy (cold therapy) after shoulder surgery in 70 patients. Patients were assigned to either a continuous cryotherapy group or an age-matched control group receiving no cold therapy. On the first day after surgery, patients receiving cryotherapy reported significantly less pain during sleep, greater comfort in bed, and more restful sleep than control subjects. The pain-reducing benefits of cold therapy persisted throughout the recovery period. These findings demonstrate that continuous cold therapy is an effective method for managing pain and improving comfort after shoulder surgery.

66Cold Therapy Reduces Pain and Narcotic Use After Rotator Cuff Repair
Journal of Shoulder and Elbow Surgery (2026) · Xiao AX, Trotter M, Sampson H, Cole EW, Feeley BT
This study assessed the impact of a standardized cold therapy protocol on pain and opioid consumption following arthroscopic rotator cuff repair. Patients who used cold therapy units after surgery experienced significantly lower pain levels and required fewer narcotic pain medications compared to those who did not use cold therapy. The findings demonstrate that cold therapy is an effective non-pharmacological approach to pain management after rotator cuff surgery, reducing both suffering and reliance on pain medications during recovery.

72Rotator Cuff Tears Increase With Age and Are Often Asymptomatic
Journal of Shoulder and Elbow Surgery (2014) · Teunis T, Lubberts B, Reilly BT, Ring D
This systematic review pooled data from 30 studies encompassing 6,112 shoulders to determine how common rotator cuff abnormalities are across different age groups. The researchers found that rotator cuff tears become increasingly common with age, rising from 9.7% in people aged 20 and younger to 62% in those aged 80 and older. Crucially, a high percentage of these tears were found in people with no symptoms at all, suggesting that many rotator cuff tears exist without causing pain. The prevalence of asymptomatic tears was high enough that the authors concluded rotator cuff degeneration should be considered a normal aspect of human aging, making it difficult to determine when a tear is new or the actual cause of symptoms.
